There is no good theory that gets gravity in the right fit, if in the formulas at all. String theory is still stalled:-http://www.newscientist.com/article/dn18612-knowing-the-mind-of-god-seven-theories-of-everything.html?full=true -And the Chicxulub asteroid is again back as the favored candidate for dinosaur extinction:-http://www.sciencedaily.com/releases/2010/03/100304142242.htm

I've read that the volcanic activity seen worldwide was a consequence to this asteroid.

The fine structure constant, also called alpha, may not be constant across the universe!! This does not fit relativity:-http://www.newscientist.com/article/mg20827830.900-constant-change-are-there-no-universal-laws.html?page=1-Only available for two more days. Sorry I'm so late with it.-An excerpt:-Webb, who is at the University of New South Wales (UNSW) in Sydney, Australia, first raised physicists' hackles about a decade ago, when he found some strange results after using the Keck telescope in Hawaii. He had been looking at quasars, which are extremely bright galaxies in the far reaches of the cosmos. As the quasar light passed through clouds of magnesium and iron atoms on its 12-billion-year journey to Earth, some of the light had been absorbed by the metal atoms.-Oddly, though, Webb's analysis said the atoms had taken up the wrong kind of light. The wavelengths of light absorbed by magnesium and iron can be predicted using the equations of quantum electrodynamics, but the ones Webb recorded were different. Twelve billion years ago, it seems, iron and magnesium absorbed photons of different energies than the ones they absorb today.-Webb did have an explanation, though. The observations fitted perfectly if he changed one of the fundamental constants of nature, known as the fine-structure constant, or alpha. This is a central pillar in quantum electrodynamics and dictates, among many other things, which photons certain atoms will absorb.-Today's value of alpha is approximately 1/137. But Webb's work showed that, billions of years ago, it must have been around one part in a million smaller.-Nobody believed the result was right, but neither could they find any flaws in Webb's analysis (Physical Review Letters, vol 82, p 884). The only other explanation was that something peculiar to the Keck telescope was to blame. So Webb turned to the Very Large Telescope (VLT) in Chile, and analysed the quasar light that it picked up.-Webb's PhD student, Julian King, has just completed the analysis. "When I started I quietly hoped we'd find the same thing Keck found," says King. "The worst case would have been no effect; then we would have had to start searching for the flaw at Keck."-King's worries were unfounded. There was an effect: as with the Keck observations, the VLT found a slightly different alpha from the accepted value. But the big surprise was that this time the constant was bigger, not smaller (arxiv.org/abs/1008.3907).

Sir Roger Penrose has a new book, 'Cycles of Time', in which he proposes that our universe is cyclical. One paragraph in the folowing website shows how delicately balanced is the Big Bang:-"In the 2007 interview (at the 6:00 mark) Sir Roger opines that the big mystery of the BB, is that all this organized universe (which includes galaxies, stars and us) must in some sense be higher in entropy, more disorganized, more random than the BB, making the BB a truly awesome state of order. One, just one, of many such organized features, is that the expansion rate of the BB would be disturbed if the universe, the entire universe, had so much as one sand grain more or less. Stephen Hawking calculated that at 1:10^60. In this tape, Sir Roger ups the ante to 1:10^123, "an absolutely ridiculously small number" he says. So we are all agreed, the BB is an exquisitely ordered explosion.-The host interjects (at 6:12), "That almost prompts the question, "Who organized it?" Sir Roger sidesteps the question in classic materialist fashion. "Some might put it that way. But I prefer to look at things in a scientific view." Ahhh, so Sir Roger has already determined that the ID question is not science. And this is the root of his crazy theory on how to explain the information in the BB while avoiding the "Who?" question. At this point everything else in his theory becomes mere justification and details, for the assumptions are laid bare."-http://procrustes.blogtownhall.com/2010/11/01/mr_hoyle,_call_your_office.thtml

"Toms has shown that quantum gravity causes asymptotic freedom in all the gauge couplings. This is handy if you want to show that all forces unify in a single (very weak) force at very high energies." David, What does this mean, every force is unified into ONE force, altho weak, at very high energies? What is a force and what is very high energy? Speaking in layman's terms of course to the best of your understanding.

What is a force and what is very high energy? Speaking in layman's terms of course to the best of your understanding.-This is a discussion of very complex higher cosmologic math in particle physics. The theory is that at the highest (electrical) energies all the 'forces' become one, and eventually that should include gravity, the weakest force. Forces: 'strong' holds the nucleus together; 'weak' allows decay of an element that is radioactive, i.e., carbon 14. Electromagnetism is another force, and Weinberg, et. al. showed years ago that it joins with the weak at higher energies, for the Nobel prize. Gravity is the last 'force' and,so far, mathematically, it won't behave in the equations to prove unification of forces, as was present in the plasma just after the Big Bang. Tom has advanced the math!
Cosmology: Earth in goldylocks zone; dangerous

A planet must be in the goldylocks zone if life is to start. But in that zone the space around the earth has a WEATHER produced by the sun that is very unhospitable to life and inanimate electronics. On Earth we are protected by ozone layer, the atmosphere itself and the magnetic field around the Earth caused by the nickel-iron core of the Earth, liquid and sloshing around inside. Everything must be perfectly tuned.-http://physicsworld.com/cws/article/indepth/44191

We don't have enough information. Claims like that are like the sheep joke I love:-An astronomer, a physicist and a mathematician decide to vacation in Scotland. In the countryside, suddenly the astronomer called out, "By jove, a black sheep! All sheep in Scotland must be black!"-The physicist replied, "No, statistically speaking only some sheep in Scotland are black!"-The mathematician looked skyward for a moment than intoned "In Scotland, there exists a field, and in the field, exists a sheep, of which at least one side is black!"-You're being an astronomer, David!

I don't know if they have life, if they crossed that enormous threshold. They are all perfectly tuned. My sheep are on Earth. None of us know if they are elsewhere.-The point of my entry was the dangerous universe and how we are locally protected.

The recent neutron stars in collision point out how dangerous our universe really is. If such a collision occurred close to use the result is disastrous:
https://www.scientificamerican.com/article/a-nearby-neutron-star-collision-could-cause-...
"A kilonova, [two neutron stars colliding] however, has different physics at play. Neutron stars are a few dozen kilometers in radius rather than a few million like a typical stars. When these dense objects merge, they tend to produce jets that blast out gamma rays from their poles.
“'[W]hat it looks like to us, and the effect it has on us, would depend a lot on whether or not one of the jets was pointed directly at us,” Frank says. Based on its distance and orientation to Earth, a kilonova’s jets would walk the fine line between a spectacular light show and a catastrophic stripping away of the planet’s upper atmosphere. If a jet is pointed directly at us, drastic changes could be in store. And we probably wouldn’t see them coming. A kilonova begins with a burst of gamma rays—incredibly energetic photons that, by definition, move at light-speed, the fastest anything can travel through the universe. Because nothing else can move faster, those photons would strike first, and without warning.
“'What [the gamma rays] would do, probably more than anything else, is dissolve the ozone layer,” says Andrew Fruchter, a staff astronomer at the Space Telescope Science Institute. Next, the sky would go blindingly white as the visible light from the kilonova encountered our planet. Trailing far behind the light would be slower-moving material ejected from the kilonova—radioactive particles of heavy elements that, sandblasting the Earth in sufficient numbers, could still pack a lethal punch.
"That’s if the kilonova is close, though—within 50 light-years, give or take. At a safer distance, the gamma rays would still singe the ozone layer on the facing hemisphere, but the other side would be shielded by the planet’s bulk. “Most radiation happens very quickly, so half the Earth would be hidden,” Fruchter says. There would still be a momentarily blinding light. For a few weeks, a new star would burn bright in the sky before gradually fading back into obscurity.
"Don’t let all this keep you up at night. Kilonovae are relatively rare cosmic phenomena, estimated to occur just once every 10,000 years in a galaxy like the Milky Way. That’s because neutron stars, which are produced by supernovae, hardly ever form as pairs. Usually, a neutron star will receive a hefty “kick” from its formative supernova; sometimes these kicks are strong enough to eject a neutron star entirely from its galaxy to hurtle at high speeds indefinitely through the cosmos. “When neutron stars are born, they’re often high-velocity. For them to survive in a binary is nontrivial,” Fruchter says. And the chances of two finding each other and merging after forming independently are, for lack of a better term, astronomically low."
Comment: The universe is dangerous but we are in the goldilocks zone where little seems likely to happen. In answer to the inevitable question of why God might have allowed this danger, I will note that these explosions make the heavier elements like gold and on up to uranium in the periodic table. God obviously evolved the universe and the available elements in this way. We do not know, and will never know, whether He chose this method or it was the only way He could do it.

For the benefit of the few people who may be following these discussions, let me correct any misleading impression they may get from such posts. Obviously the universe evolved in this way. There is absolutely nothing “obvious” in the claim that God did it. And if God exists, it doesn’t say much for his “full control” if there was no other way. There are more such problems under “causality weirdness”:
DAVID’s comment: As weird as ever. Quantum mechanics is the basis of the universe. How can we understand God if His mechanics are so illogical?
There are many unexplained phenomena in the universe. Firstly, the puzzles are not solved by introducing another puzzle in the form of a sourceless, unknowable, invisible, conscious being, and secondly the seeming illogicality of quantum mechanics is no reason to believe in illogical explanations of evolution and to reject logical explanations.
DAVID: (under “all over Africa"): I'm still with Adler. God is a person like no other person. Which means our human logic doesn't apply.
dhw: If God is pure conscious energy that is capable of creating a universe, he is not a person anyway. But that doesn’t mean your humanly illogical explanations are right and my humanly logical explanations are wrong!
DAVID: Thank you for accepting that God is different!
dhw: If he exists, of course he’s not a human being. God being “different” is no reason for believing an illogical hypothesis and rejecting a logical one.
DAVID: Your 'logic' is not my logic.
You admit that my logic explains mysteries that your logic can’t solve, but you say “our human logic doesn’t apply”. So you can believe your illogical human logic, and you reject my logical human logic. Not much logic in that!

The theories we are discussing are THEISTIC: you can’t explain why your God made the universe so big, or why he designed eight stages of whale, or why with his ability for instantaneous speciation he had to design the weaverbird’s nest and the skull-shrinking shrew and umpteen hominins and hominids before he produced the one species he really wanted to produce.

Evolution never invented anything. Only organisms can invent. That leaves you with a stark theistic choice: Do you think your God preprogrammed mussel fibre stretching 3.8 billion years ago (as part of his effort to keep life going till he could produce the brain of Homo sapiens), personally intervened to teach mussels how to do it, or provided them with the intelligence to work it out themselves?

A hypothesis is not a description, it is an explanation! We both agree on the history: the bush of life exists, it resulted from evolution, life needs energy if it is to continue. In the context of this particular discussion, we are both looking for a THEISTIC explanation of this history. Your theistic explanation or, in most cases, non-explanation is that God evolves his purposes except when he doesn’t (instantaneous creation of species at the start of the Cambrian); God specially created eight stages of whale, though you don’t know why; God specially designed the weaverbird’s nest in order to keep life going until he could fulfil his prime purpose of producing the brain of H. sapiens, though life would have kept going anyway without the whale and the nest; God specially created the large universe but you don’t know why; and God’s logic is not ours. By contrast, my theistic hypothesis provides an explanation for the whole history, as you acknowledge.

I don’t know what word you expect me to take. We agree on the history, and we both offer a THEISTIC explanation of that history. The theistic viewpoint I offer is that of a God creating life as an ever-changing spectacle, part of which is human behaviour. Your viewpoint is that God created the ever-changing spectacle in order to produce humans who would think about him and have a relationship with him. I propose a free-for-all set in motion by God’s design, and you propose total control. I’m afraid that calling my hypothesis “descriptive” does not make it any less of an explanation of history from God’s viewpoint than your own.

And I suggest that a God who invents a mechanism that can produce the whole bush of life is no less inventive than a God who invents each and every innovation, lifestyle and natural wonder individually, either through a 3.8-billion-year computer programme or by means of personal dabbling.

DAVID: Please take my word for it. I view your hypothesis as descriptive of the history we know. I explain history as I see it from god's viewpoint. Yours is a viewpoint from non-acceptance of God.
dhw: I don’t know what word you expect me to take. We agree on the history, and we both offer a THEISTIC explanation of that history. The theistic viewpoint I offer is that of a God creating life as an ever-changing spectacle, part of which is human behaviour. Your viewpoint is that God created the ever-changing spectacle in order to produce humans who would think about him and have a relationship with him. I propose a free-for-all set in motion by God’s design, and you propose total control. I’m afraid that calling my hypothesis “descriptive” does not make it any less of an explanation of history from God’s viewpoint than your own.
Yes, the bush of life offers a spectacle for us in its marvelous diversity. That doesn't mean God has to view it that way. All I accept is God created it. But it was on the way to a greater creation in the human brain. You see God as having enjoyment. I see Him as purposeful, while 'enjoyment' is an unknown proposition. You take what we see beyond an way of proving your suppositions. All I know is what I see He created and presume that was His purpose.
dhw: So let’s just be clear: God personally dabbled mussel fibre stretching, or preprogrammed it 3.8 billion years ago, because without it life could not have gone on to enable him to produce the brain of Homo sapiens.DAVID: No it is a side event of an eco-niche.

Neither of us can prove any of our hypotheses (there are no suppositions, except in your case the existence of God.) You keep talking about purpose. My theistic hypothesis, like yours, is that he purposely created what he created (in mine, he purposely created a free-for-all, with the option of dabbling). But the question is the purpose of his creating what he created! Enjoyment is a purpose, but the only purpose you have offered us for the whole vast bush of life extant and extinct is the production of the human brain so that we can think about God and have a relationship with him. Hardly a purpose for specially designing the eight-stage whale, the weaverbird’s nest, the toxin-swallowing snake, or the skull-shrinking shrew.

Enjoyment is a concept, not material, and therefore just theory, which is probably not real in any sense. The human brain is here, it is real and doesn't need to be here from a survival standpoint. What more proof do you need?

Yes indeed, if God exists and invented the mechanism, then it must be a God-invented mechanism. And yes indeed he is still in charge and in control if he chooses to dabble, but otherwise the whole point of the mechanism would be to give cell communities autonomous physical control over themselves (as they adapt to or exploit the environment), just as you maintain he has given humans autonomous psychological control over themselves (free will). He sacrifices control when it suits his purposes, but may possibly also dabble when it suits his purposes.

"Toms has shown that quantum gravity causes asymptotic freedom in all the gauge couplings. This is handy if you want to show that all forces unify in a single (very weak) force at very high energies." > > David, What does this mean, every force is unified into ONE force, altho weak, at very high energies? What is a force and what is very high energy? Speaking in layman's terms of course to the best of your understanding.-To add to David's explanation; the state of ultra-high energy is what the universe was immediately after 'ground zero' of the big bang. All mass and energy that exists was compressed into a kind of "container" that was too big to hold it; too hot and too energetic for atoms. This is when our universe was made of the stuff smaller than quarks and neutrinos.

David has alerted us to the latest sensation in physics, and calls it "a possible BIG step to a unified theory".-I struggle with the physics, but in all these sensational new discoveries there is usually a sting in the tail that is obvious even to the layman. This one is no exception: -"That must be good news for physicists working in unification."-"Sort of. Toms has shown that quantum gravity causes asymptotic freedom in all the gauge couplings. This is handy if you want to show that all forces unify in a single (very weak) force at very high energies. However, he treated quantum gravity by simply quantizing Einstein's general theory of relativity. This approach breaks down at the very energies that unification is expected to occur. To take things further, physicists would need to integrate more exotic aspects of quantum gravity such as additional dimensions and supersymmetry."-All you need for your unified theory, then, is confirmation of various other theories in such a way that you can unify them.

Cosmology: Latest theories of everything

Hi David: Thanks for the comment on Crazy Cosmology. Though I must admit to a general, rather casual use of terminology, I disagree with the view that atheism is not an ideology. It is a doctrine, an orientation that characterises the thinking of a group or nation, or an Imaginary or visionary theorization of a Universe without a God. That is an ideology!
I was quite appalled to read some very rude and rather nasty remarks made about people who support the modern, fact based standard physics of cosmology, rather than a fevered rhetoric about the sanity of latter day thinkers who question the establishment version/function of redshift. Questioning the professional capability of Halton Arp, a very distinguished astronomer, who was a protégé of Edwin Hubble and a senior observer at the Palomar Telescope for 20 years, is of itself, puerile.
His life was ruined when he displayed a photo of two neighbouring galaxies linked by redshift, thus questioning its interpretation. NASA then engaged in demonstrating that might is right (shades of Hitlerism) and only NASA could be right, by forcing him out of work and consequently out of the USA! Their cohorts, Sagan and others had tried it on with a great and original thinker, Immanuel Velikovsky. They ‘caught a cold’ with that one and made him a millionaire!
More nasty comments were directed at the ideas promoted by the Electric Universe people (very happy to be among them!) that space is far from empty and is composed of the fourth state of matter: plasma. Sadly, for them, even NASA accepts that it is fact!
Dr Dennis Gallagher, a plasma physicist at NASA's Marshall Space Flight Center, says "Very little material in space is made of rock like the Earth."
Plasma is not a gas, liquid, or solid - it is the fourth state of matter. Plasma often behaves like a gas, except that it conducts electricity and is affected by magnetic fields. On an astronomical scale, plasma is common. The Sun is composed of plasma, fire is plasma, fluorescent and neon light of the Universe is made up of plasma https://science.nasa.gov/science-news/science-at-nasa/1999/ast07sep99_1
The visible universe is 99.999% plasma. So quite simply, if you don't know how cosmic plasmas behave, you don't know the Universe. And astrophysical plasmas https://www.plasma-universe.com/Astrophysical_plasma may behave differently to terrestrial plasmas.
It is worth noting that all cosmic plasma carries a magnetic field and electric currents. Even plasmas that are less than 1% ionised, may behave as a plasma, as do dusty plasmas (ie. "dust grains can be the dominant current carrier").
https://www.plasma-universe.com/99.999%25_plasma
I ask ‘him’ to answer one question – without calling upon imaginary forces emanating from a totally imaginary pre-existing Universe, God or whatever.
Here it is:
How can the current Universe of millions of huge galaxies have been condensed into a ‘Singularity’? Failure to show how this can be done automatically destroys Big Bang theory.
Calling upon the notion that assumptions are proof, rather than as the subject of discussion, signals the bankruptcy of that whole scenario.
Moving on: Sir Roger Penrose is selling a book. This class of book flourishes by proposing, rather than solving ‘mysteries. His opinions are – I fear – clouded by the equivocation that so often characterises the views of ‘experts’, who are primarily motivated so as not to aggravate their relations with other ‘such experts’.
I have no such impediment!
The mathematical analysis made Stephen Hawking has about the same theoretical as did Ptolemy's model of the solar system! I.E. None.
Penrose avoided the question because he is out touch with reality. Like Hawking, he has no proper answer as to how and why evolution seems so directed by Mother Nature. I do!
He cannot ‘explain’ the Big Bang, primarily because it didn’t happen! For it to have happened, there must first have been a Singularity! More equivocation!
The Universe looked at as Eternal, with Redshift – as suggested by Hubble in his 1936 lectures - as a new principle of Nature and NOT representing utterly incredible speeds of recession would leave a virtually unchanging Universe.
But: in an eternally stationery Universe, none of current ‘theology’ would be even considered! AND no research money from commercial interests!
The many ‘new’ effects that have been claimed as ‘evidence, would be more correctly interpreted only in the light of the already proven physical law. There is page after page of such rational explanation, which also acknowledges that they too are, as yet unproven ideas. That is real science and the ‘Establishment’ are scared stiff of it.
Its acceptance will entail (hopefully) the collapse their current fairy tale cosmology and their replacement by new age science and scientists.

Although I share reblak’s scepticism concerning the Big Bang theory, I am in no position to take an active part in this discussion. However, David, since you have always prided yourself on your independence of mind (I doubt if many folk agree with you that your God preprogrammed or privately dabbled every innovation, lifestyle and natural wonder for the sole purpose of producing humans), may I gently suggest that reblak’s arguments should be treated on their merits and not on what the scientific Establishment currently favours.

Thank you for the reference. It leads to several others which I have read, which lead back to Hubble's own doubts about the meaning of the red shift, and that the color change can be due to other factors as the light passes through space. The Big Bang, of course, is a theory, not a fact. The raising of controversial points is he best way science works.

"But I don't understand the 'commercial interests' comment. We are not going to colonise the universe." No -hopefully! Virtually all astronomy is supported by private interests. This is so for NASA who’s funding is controlled by those same commercial interests that in practice control government funding. Billions of dollars are involved.If you imagine that commercial interest is not involved, try telling that to the Marines! Universities have 'chairs' etc funded in a similar manner. Consequently, the public purse etc.will not countenance any suggestion that the heart of cosmology lives up a gum tree! If you need an example of ‘commercial interest’, try ‘Boeing Defense, Space & Security’ for starters!
If you doubt the power of money (particularly in the USA), look at their sociologically insane Gun Law!
It was mentioned that Biology does not work by the accretion atomic structures.I most definitely disagree! I feel sure that you didn't mean what you said. Everything works that way - everything. The place where things change and progress in advanced biology is within the gene bank, influenced at times by outside forces that may damage or destroy tissue but sometimes have a positive result in reordering the gene bank and so fostering a new species.
The same rules apply - any modification must be atomically acceptable by the existing structure or no 'modification' can result. The probably intrinsic nature of the outcome dictates and limits the next acquisition - and so on. Simple because Nature can manage only tiny steps and does not'do' arithmetic.
Like it or not, what I here demonstrate (in layman's terms) accounts for Evolution. The origin of life itself poses a possibly unanswerable problem. However, the same class of problem applies to the origin of the constituent parts of atoms. The answer is the same as before. Matter is eternal, as are its effects. We cannot ‘make’ an atom without using bits of other atoms. Perhaps life is also an eternal ‘element’. The trouble with this idea is that unlike atoms we cannot take life apart. So, it remains an enigma!
Once you see how this can work (accepting for a moment my thesis), the next steps will only be possible if sensitive, chemical awareness has been attained. This ability is demonstrated in even the most primitive life forms. An organism can live on sunlight but must develop a form of photo synthesis to do so. In this case, sunlight acts as an ‘exterior force’ that directly influences its botanical recipient to select further advantageous chemical (atomic!) structures. Thus is born the level of photo synthesis we see and love.
This magical assemblage is called life because it has the ability to regenerate itself into distinct and separate offspring. It should be noted that every cell in any offspring is itself distinctly alive and dies principally because the blood supply has been cut off.If it cannot do this, it is not alive. In a very marginal way, the inorganic material called crystal can also reform itself, but these seeming ‘additions’ have no independent existence and are most definitely not alive!
The variety of life forms is extraordinary, whereas the inorganic formations are few. To offer an analogy, perhaps Mother Nature is the peasant sowing her field with dormant seed which will bloom in the Spring. A nice picture but it will find few buyers!
Now for the 'pebble' etc. “Out of the Blue” is a euphemism that, I suggest, betrays an attitude of mind that has chosen not to accept that the laws of nature entail influences that ‘open doors’ to a range of possible and automatic outcomes. If they didn’t there could be no mechanism for any change – at all! If you dispute this please suggest an alternative!
In the ‘polemic’, much is made of some meaningless drivel. I think I agree with the laughing off those silly ideas and the conclusions he draws, but his wording rather confuses me. My ideas stem from my adoption as a child of the atheist ideology, which I freely admit was extensively discussed with my atheist father. One of his big points was his insistence that I take nothing for granted, even his ideas. This led me to read every word in my school version of the Bible. I achieved top marks in every test. The religion mistress asked me “Why”? I said that for me not to believe something I needed to know and understand what is wrong with it.
This has proved to be of fantastic value to me in arriving at my personal idea of logical opinions rather than being drawn into 'joining the crowd’. I find, (sadly in my opinion) few thinkers, especially the religious, approach what are - in truth mind problems - using only logic.
Human emotions readily affect our thinking (and quite rightly so) but we need to see that we do not use them to override our reasoning.
The concept of ‘use’ has no place in natural activity. Evolution simply allows nature to evolve as its potential dictates. Therefore a discard in whole or in part must surely entail distinct processes that, eventually, so act.
More to come!

John: "But I don't understand the 'commercial interests' comment. We are not going to colonise the universe." No -hopefully! Virtually all astronomy is supported by private interests. This is so for NASA who’s funding is controlled by those same commercial interests that in practice control government funding. Billions of dollars are involved.If you imagine that commercial interest is not involved, try telling that to the Marines! Universities have 'chairs' etc funded in a similar manner. Consequently, the public purse etc.will not countenance any suggestion that the heart of cosmology lives up a gum tree! If you need an example of ‘commercial interest’, try ‘Boeing Defense, Space & Security’ for starters!
I certainly can see that aspect of the commercial side you point out.
John: It was mentioned that Biology does not work by the accretion atomic structures.I most definitely disagree! I feel sure that you didn't mean what you said.....Simple because Nature can manage only tiny steps and does not'do' arithmetic.
You are apparently not aware of Gould's punctuated equilibrium theory to explain the huge gaps in the fossil record. Tiny steps have not been demonstrated. Darwin hoped the Cambrian Explosion could be explained by finding intermediate forms. So far with new areas in Canada and China from that period, nothing fills the gap.
John: The origin of life itself poses a possibly unanswerable problem. However, the same class of problem applies to the origin of the constituent parts of atoms. The answer is the same as before. Matter is eternal, as are its effects. We cannot ‘make’ an atom without using bits of other atoms. Perhaps life is also an eternal ‘element’. The trouble with this idea is that unlike atoms we cannot take life apart. So, it remains an enigma!
On the other hand biologic research has taken cells apart so the mechanisms are known. Cells are like giant factories, constantly in production of proteins, following instructions from their individually modified genomes.
John: Once you see how this can work (accepting for a moment my thesis), the next steps will only be possible if sensitive, chemical awareness has been attained. This ability is demonstrated in even the most primitive life forms.
Yes, even bacteria are constant factories, in general reproducing themselves every 20 minutes
John: This magical assemblage is called life because it has the ability to regenerate itself into distinct and separate offspring. It should be noted that every cell in any offspring is itself distinctly alive and dies principally because the blood supply has been cut off.If it cannot do this, it is not alive.
Actually cell death in multicellular organisms is constantly programmed, with planned replacement, not related to blood supply.
John: The variety of life forms is extraordinary, whereas the inorganic formations are few.
We here all agree and refer to the bush of life with many strange and exotic branches
John: Now for the 'pebble' etc. “Out of the Blue” is a euphemism that, I suggest, betrays an attitude of mind that has chosen not to accept that the laws of nature entail influences that ‘open doors’ to a range of possible and automatic outcomes. If they didn’t there could be no mechanism for any change – at all! If you dispute this please suggest an alternative!
By laws of nature do you mean natural selection? Without a copy of a reference to what you are referring, I don't follow what you wrote..
John: In the ‘polemic’, much is made of some meaningless drivel. I think I agree with the laughing off those silly ideas and the conclusions he draws, but his wording rather confuses me. My ideas stem from my adoption as a child of the atheist ideology, which I freely admit was extensively discussed with my atheist father.
That certainly explains your atheism background.
John: Human emotions readily affect our thinking (and quite rightly so) but we need to see that we do not use them to override our reasoning.
I've always accepted the fact that emotions get in the way of logic.
John: The concept of ‘use’ has no place in natural activity. Evolution simply allows nature to evolve as its potential dictates. Therefore a discard in whole or in part must surely entail distinct processes that, eventually, so act.
More to come!
Does that comment mean you do not accept the theory of natural selection?

Here is some more! The vexed question regarding the existence of any god is paramount for atheists, agnostics and believers. It is a prime example of the 'difficulty' encountered in proving a negative. Whilst I can show reasons to believe that something isn't there, this falls short of proof positive. There is always the 'what if' brigade to contend with. The most I can offer is as follows.
The real presence of something is made plain in at least two or three ways. We may see, feel or hear it. With modern technologies, we can 'see' the invisible!
We cannot 'see' something that isn't there - or is insubstantial - such as an idea, though we can detect the energy waves that indicate its process.
God is classed as physically 'insubstantial', so its presence cannot be detected. Other than by claims made by its ardent proclaimers, no evidence whatever is available that proves its existence. One may say that any ongoing peculiarity that presently remains unexplained is only explicable by the acts of God. This line of reasoning presently has (as its mainstay) the enigmas of an obviously positively, directed evolution and of life itself.
I maintain that my explanation of evolution (whatever its theoretical faults) is fundamentally sound and removes this feature from rational discussion. It adds an enormous dose of reality to the atheist argument. Life itself may be perhaps an element, like every other force of nature, but requiring specific conditions to become apparent.
So – (I maintain ) – the argument boils down to choice. Either you (emotionally) go for a religious stance and damn the consequences, or you adopt sit on the fence agnosticism. If this latter does not cut the mustard, it’s the dreaded atheism for you!
What I see as ‘consequences’ is that you honour a belief in a God that is Almighty, unlimited in any way, that permits evil/misguided men (principally) to commit unspeakable cruelties upon all and sundry. It allows the decent peoples of (particularly) the western ‘democracies’ to wallow in comfort while watching TV reports of children dying in their hundreds of thousands. To think it ‘tough titty’ for desperate folk to drown fleeing their persecutors and so on.
In my opinion, no God - having created the Universe - would permit these insults to its integrity, not for a second. Nor require humanity to worship or ‘adore’ it (or even believe in it). The perhaps most notable attributes plastered on to the godhead, are the straight up and down political requirements of human dictatorship. Damn all to do with the wishes and purposes of an Almighty God, but wonderfully handy for a dictator!
I come back to why I am an atheist. I have Nature all around me and I understand that Mother and in Nature has achieved all this aided only by pre-existing physical laws. The plethora of conflicting ideologies are very adequately resolved and any others disposed of by using Occam razor.
The atheist argument was amusingly exemplified by Dave Allen many years ago. His story featured an atheist arguing with a Pope. After hours of fruitless discussion, the Pope says, “You are like a blindfold man in a lightless room looking for a black cat that isn’t there.”
The atheist replied, “No! It’s you who is like a blindfold man in a lightless room looking for a black cat that isn’t there. Only - You Found It!”
There is nothing wrong with Agnosticism as a medium in which you may consider what is, for yourself at least, an unresolved question. In that sense, we can logically widen the scope of agnosticism to include controversies such as those concerned with politics. Religion is in my opinion deeply rooted in politics.
“... it is the separate coming into being of the living, self-reproducing primeval organisms, the hitherto unthought-of even if the primeval eye, ear, nose, lung, heart, penis, vagina, etc., that presents the problem. Darwin himself understood this, and so refrained from discussing such origins.”
Darwin laboured without our modern day knowledge and his thinking hampered by a gradually diminishing religious belief. That can leave a thinker in a disturbed state of mind.
I (at least) am confidently aware of the natural and automatic way that Mother Nature performs these amazing acts of creativity. The simple proof of my explanation is the total absence of any other natural alternative! Chance – a mathematical concept – has little bearing on the works of Mother Nature. Dawkins and co. are plain wrong. Numbers can often lead to a likely conclusion – they do not create the events they may explain in terms of human understanding. One example will do.
Flipping a coin will get heads or tails. 100 flips should be 50-50 but that is highly unlikely as the force that produces heads will not produce tails! In the absence of a full understanding we employ chance to cater for uncertainty.
Natures forces do not obey laws invented by man!

john: God is classed as physically 'insubstantial', so its presence cannot be detected.

One may say that any ongoing peculiarity that presently remains unexplained is only explicable by the acts of God.

This is certainly the way to look for evidence of God in his works as the Quran states.
John: I maintain that my explanation of evolution (whatever its theoretical faults) is fundamentally sound and removes this feature from rational discussion. It adds an enormous dose of reality to the atheist argument. Life itself may be perhaps an element, like every other force of nature, but requiring specific conditions to become apparent.
We have no idea how life began, but it certainly required 'specific conditions', which are the organic chemistry of life coming together, and it seems miraculous.
John: What I see as ‘consequences’ is that you honour a belief in a God that is Almighty, unlimited in any way, that permits evil/misguided men (principally) to commit unspeakable cruelties upon all and sundry.
The cruelty of humans exists because God gave humans free will. The cruelty is no God's fault.
John: “... it is the separate coming into being of the living, self-reproducing primeval organisms, the hitherto unthought-of even if the primeval eye, ear, nose, lung, heart, penis, vagina, etc., that presents the problem. Darwin himself understood this, and so refrained from discussing such origins.”
And it an issue that cannot be avoided in any consideration of life and evolution.
John: Darwin laboured without our modern day knowledge and his thinking hampered by a gradually diminishing religious belief. That can leave a thinker in a disturbed state of mind.
I don't think Darwin was disturbed. In my view he became agnostic, but he certainly labored without much real knowledge of what we now know.

You still have not explained your concept of 'Mother Nature'., or where the laws of nature come from.

We don't invent, but find reasonable laws of our reality which rationally fit how nature works.

I have selected this particular statement as I think it epitomizes the problem I have with your approach. As an agnostic, I cannot find a satisfactory explanation for the “amazing acts of creativity”. David attributes them to a sourceless supernatural being who consciously designs them. Most atheists I know attribute the original spark of creativity to unconscious chance. You attribute it to Mother Nature. But if Mother Nature is neither a conscious being nor chance, what is she? What do you mean by “natural and automatic”? Are you saying that life, consciousness, and the eye, ear, nose, lung etc. were the inevitable consequence of the existence of matter in which atoms combine, so they don’t need explaining? I would regard this theory as requiring just as much faith as belief in a god or in chance.

Well now! Are you pulling my leg? Here I was thinking how well I had made my point. OK – OK. I’ll give it another go.
The laws of nature are spoken of as such simply to describe how all that we see around us came into being. Some see it as an act of God – others, like myself, believe that it is solely what I think of as nature. To describe this as being the work of nature is a virtually universal practice. All I am doing is giving the workings of the natural world a very common name, a euphemism – Mother Nature. For me this is a desirable ‘humanising’ of the abstract idea of nature, making for ease of expression when conveying abstract ideas.
It has absolutely nothing to do with faith – in the religious sense. For an atheist, faith means that, in the absence of absolute proof, we believe that the ideologies we accept, will indeed eventually lead to that absolute confirmation. This is the logical acceptance of rational expectation.
Many heroic people have endured years of unjust conviction and cruelty while imprisoned, sustained by faith in their ability to survive. That is not some mystic belief, simply real belief in their power to survive. So, when I say ‘Mother Nature’ did this or did that, or works like this (or that!), I refer to purely physical actions. The term Mother Nature (which I am quite certain you fully understood!) is a long term favourite of mine.
Chief among those actions is how Mother Nature deals with evolution. As I do not see any problem with “amazing acts of creativity”, I must assume that some extra degree of explanation will help.
Forgive me if I prove repetitious.
First off, Mother Nature has, of course, no ‘awareness. ‘She’ is simply the (euphemistic) character I have described.
So, the laws of physics determine the outcome of atomic activities. Let’s me be clear on this. ALL physical actions are the result of the engagement of atomic activity. Molecules, cells etc are complex structures and are themselves affected and altered either by the acquisition of atoms or other biological ‘structures’ created by simple atomic conjunction. Unless you favour some God or other, what other possible manner of creation can there be?
Mother Nature is not subject to any other kind of influence.Therefore, (surely ) any actions these forces of nature engage in must be automatic. If you don’t accept this you are obliged to call on some magical power or some enormously powerful natural intelligence. I have previously, at length, described how it simply must work, using a simple analogy such as the unquestionably automatic formation of water as base point example.
It is of no extra importance whether a single celled ‘being’ or the final addition to the most complex structure in a human brain is being formed, only the simplest possible (at this stage) atomic/molecular ‘addition’ can be made.
I don't see any rational alternative.
I quite expect that my theory will soon see the ‘scientific’ light of day, just explained in more accurate, more biologically correct scientific terms.
There’s faith for you!
As I may have already suggested, these ‘write ups’ take hours of typing, revising, struggling to be unambiguous, leaving me going to bed at insanely late hours (00.10 now), but I will find some web stuff you asked for.

Thank you, reblak, for your detailed response. I am going to cherrypick and juxtapose a few quotes in order to explain the problem that I have with your theory. I appreciate how time-consuming this is. I also spend far more time than I should on these discussions, but I also learn a great deal from them, and so perhaps you will contribute to the hoped-for enlightenment, and perhaps the rest of us might even give you something new to think about as well.
reblak: The laws of nature are spoken of as such simply to describe how all that we see around us came into being. Some see it as an act of God – others, like myself, believe that it is solely what I think of as nature.
So all that we see is the product of Nature, which is impersonal, unconscious, and acts automatically. No problem with the definition of Nature.
reblak: It has absolutely nothing to do with faith – in the religious sense. For an atheist, faith means that, in the absence of absolute proof, we believe that the ideologies we accept, will indeed eventually lead to that absolute confirmation. This is the logical acceptance of rational expectation.
You believe that your ideology is correct. So does a theist. Your irreligious faith is that life is the product of an impersonal, unconscious force. Again no problem of definition.
Reblak: Chief among those actions is how Mother Nature deals with evolution. As I do not see any problem with “amazing acts of creativity”, I must assume that some extra degree of explanation will help.
This is where the alarm bells ring for me, because I do have a problem with “amazing acts of creativity”. While adhering to my agnosticism for very different reasons, I am acutely aware of and mystified by the complexities of living things. However, I also accept the following:
reblak: So, the laws of physics determine the outcome of atomic activities. Let’s me be clear on this. ALL physical actions are the result of the engagement of atomic activity. Molecules, cells etc are complex structures and are themselves affected and altered either by the acquisition of atoms or other biological ‘structures’ created by simple atomic conjunction. Unless you favour some God or other, what other possible manner of creation can there be?
The fact that all organisms are composed of tiny pieces added to and interacting with one another does not help me to understand how they are able to reproduce, to evolve, to acquire consciousness or, in our case, an extreme form of self-awareness. Even we, with our extraordinary intelligence, have so far been unable to put atoms together and create a living being that combines all these attributes. If we do one day succeed, that will hardly prove that an intelligent mind is not needed! And this leads to your next point:
reblak: Mother Nature is not subject to any other kind of influence.Therefore, (surely ) any actions these forces of nature engage in must be automatic. If you don’t accept this you are obliged to call on some magical power or some enormously powerful natural intelligence.
Absolutely right. If Nature is unconscious and automatic and Nature produced life, then the complexities of life have been produced unconsciously and automatically. But that is your faith. And if someone rejects your faith, he must believe in some kind of God. And that will be his faith. See my summary below.
reblak: It is of no extra importance whether a single celled ‘being’ or the final addition to the most complex structure in a human brain is being formed, only the simplest possible (at this stage) atomic/molecular ‘addition’ can be made.
Yes, the process entails the addition of atoms/molecules, but the fact that you believe the process is unconscious and automatic is totally separate from the fact that complexity arises out of additions.
reblak: I don’t see any rational alternative.
To sum it up: there are two possibilities (I’ll ignore my own panpsychist alternative). 1. The complexities of life came about through an unconscious (natural) process of combining atoms. But even we highly intelligent humans are not yet able to understand or reproduce this process, and if we could, that would be the result of genius-scale intelligence and not of unconscious natural processes. Belief in the creative genius of unconsciousness requires faith. 2. The complexities of life came about through a conscious mind combining atoms. But belief in an unseen, sourceless conscious mind so vast and powerful that it can create a universe etc. etc. (I needn’t preach to an atheist) requires faith.
I see both possibilities as requiring irrational faith. That is why I remain an agnostic.

Faith: “strong or unshakeable belief in something, esp. without proof or evidence” (Encarta). Don’t get me wrong on this. I am not attacking faith. But it is obvious that the evidence either way is not strong enough to support a general consensus on the subjects we discuss and since, as you say, none of us can KNOW the truth, there has to come a point at which belief abandons reason. Hence irrationality. Faith is NOT the only alternative left. The alternative to faith is to remain open-minded. That obviously applies to the choice between chance and design, but I am even open-minded enough to consider forms of design that do not depend on David’s personal concept of a god.

Again I must stress that I am not attacking your faith, and I find your arguments concerning design perfectly logical. However, you believe in a supernatural being large and powerful and knowledgeable enough to create a universe and life, you haven’t a clue how it could have come into existence but you assume it has always been there for ever and ever, even though you’ve never seen it because it deliberately hides itself, and you acknowledge that you can’t know any of its attributes. Do you really think this belief is rational? Something brought life into existence. That is as far as reason can take us. Your faith that the “something” could be an unknown and unknowable superbeing is as irrational as the faith that it could be a stroke of luck.

Yes, something brought life into existence. What you skip in your discussion is that the biochemistry of life is so complex to create it logically requires a planning mind. The ID logic never goes any further. Can you go that far?

No, the complexity of the biochemistry of life requires a planning mind to develop and design it. We all can identify design when we see it. Design requires a designer.

And I have said many times over, I find this argument perfectly logical. I have not skipped it. But as I have said many times over, there is another argument that counterbalances it: the sheer incredibility, not to mention the lack of evidence, of a single sourceless mind that can create and encompass a universe, is unknown and unknowable and, according to you, deliberately hides itself. In two of your posts today (concerning water and our special position in the Milky Way), you make the point that we are a very special planet. True. So if you can believe in conscious energy that is eternal and infinite, why should you not believe in eternal and infinite matter and energy endlessly forming an INFINITE number of different combinations until at last it produces one that is “special” – the atheist’s stroke of luck? In fact, I would expect other planets to be capable of harbouring life, but not necessarily to have life. The really big stroke of luck would be the formation of the first living cells. But no, I don’t believe it. I find it as difficult to believe in as a single hidden, universe-encompassing, omniscient mind that never came from anywhere. And yet, as I have said many times over, one of these equally incredible hypotheses must be nearer the truth than the other: the agnostic’s dilemma.

DAVID: There can only be chance or design. dhw hunts for third ways which don't exist.
DHW: Faith: “strong or unshakeable belief in something, esp. without proof or evidence” (Encarta). Don’t get me wrong on this. I am not attacking faith.

That obviously applies to the choice between chance and design, but I am even open-minded enough to consider forms of design that do not depend on David’s personal concept of a god.
Ah, but my old friend, even the option of remaining open-minded is a form of FAITH. It is FAITH that we WILL eventually have enough information to be able to, not make a choice, but to not NEED to make a choice because the answer is utterly obvious. And that is, to me, where your logic fails.
If Agnosticism is a type of Faith, then we have three types of Faith:
- Faith that there is a God of some form.
- Faith that there is NOT a God of some form.
- Faith that one day we will KNOW if there is a God of some form.
Now, if you have no Faith in God, and are not Agnostic, then your only recourse is Evolution. if you have faith that we will one day KNOW, you withhold making a choice, then you do not WANT to make a choice. The question becomes WHY don't you want to make a choice. Obviously, Evolution does not hold up to critical inspection. But the alternative is God. So the question is, if evolution is discarded because of lack of evidence, and the only alternative is God, then WHY are you afraid to commit to there being a God? Is it because if you have to commit to acknowledging that there is a God, then you must also make a choice between a Personal God or a Nebulous God?
Having to make that choice leads to another choice that must be made. If it is a nebulous God, why did he do it? If it is a Personal God, why did he let things get to this state? The idea of a Nebulous God is, in its own way, as terrifying as Evolution, because it means there is no point to any of this. And if there is no point, you have to answer hard questions about pain and suffering. What could possibly be worth all the pain and suffering in the world if all of this is pointless? Why bother?
The choice of a personal God is even more terrifying, because then comes the question of accountability. Were we wrong? Did we make choices that make us too unworthy as to be be beyond redemption? Why did he allow all of this pain and suffering? What kind of special asshole must he to let it go on like this?
So, I would like to know why YOUR brand of faith is better or worse, in your eyes, then other brands of faith. And yes, it IS better in your eyes because it is the brand of faith YOU CHOSE. (I don't mean that to sound as caustic as it does, but I know no better way to phrase the question.)

Ah, but my young and very dear friend, I’m sorry, this is a basic premise I totally repudiate. I have absolutely no faith that we will eventually have enough information etc. etc. If there is no God, which I regard as a 50/50 possibility, then I can see no way I can ever possibly know the truth. That’s it. There is no faith whatsoever, because I simply do not know what to believe. But if I have a revelation during my remaining years, I'll let you know!
TONY: Now, if you have no Faith in God, and are not Agnostic, then your only recourse is Evolution.
I’m sorry again, but this is a complete non sequitur. Evolution has nothing whatsoever to do with the existence of God. It is a theory concerning how different forms of life developed from earlier forms, as opposed to their having been separately created. It does not in any way preclude the existence of God, who may well have invented the whole system. Who says so? Darwin himself: “I see no good reason why the views given in this book should shock the religious feelings of any one.” (Origin of Species) You have fallen for atheistic neo-Darwinism, which I as an agnostic plus millions of your co-theists reject.
TONY: WHY are you afraid to commit to there being a God? Is it because if you have to commit to acknowledging that there is a God, then you must also make a choice between a Personal God or a Nebulous God?
I am not afraid to commit. I am unable to commit. But during our discussions on the hypothetical nature of a hypothetical God, I am happy to discuss its possible nature.
TONY: The idea of a Nebulous God is, in its own way, as terrifying as Evolution, because it means there is no point to any of this. And if there is no point, you have to answer hard questions about pain and suffering. What could possibly be worth all the pain and suffering in the world if all of this is pointless? Why bother?
Why do you find it terrifying? The world is as full of beauty and love as it is of pain and suffering. I deplore the pain and suffering, but I do not see my love for my family and friends as pointless, or human attempts to relieve pain and suffering as pointless, or life itself as pointless even if it ends when we die. I would rather be happy now than unhappy. Why is my, your, and everybody else’s quest for personal happiness pointless?
TONY: The choice of a personal God is even more terrifying, because then comes the question of accountability. Were we wrong? Did we make choices that make us too unworthy as to be be beyond redemption? Why did he allow all of this pain and suffering? What kind of special asshole must he to let it go on like this?
Good questions, and one cannot discount the terrifying possibility of a sadistic God, just as one cannot discount the possibility of a loving God or an indifferent God. But what stops me from making a choice is that none of the arguments for and against the existence of God are sufficiently convincing for me to take the leap of faith required to make a decision. I don’t know why this is so difficult for both theists and atheists to understand.
TONY: So, I would like to know why YOUR brand of faith is better or worse, in your eyes, then other brands of faith. And yes, it IS better in your eyes because it is the brand of faith YOU CHOSE. (I don't mean that to sound as caustic as it does, but I know no better way to phrase the question.)
No faith involved, as explained above. And I do not regard my inability to choose as better than your choice or the choice of an atheist. However, when theists or atheists present their arguments, I try to explain why I can’t share their faith, just as you try to explain to atheists and different brands of theists why you can’t share their faith.

It seems to me, not surprisingly perhaps, that atheism presents an unambiguous view of nature. Together with the extension of its logic in considering the state of ‘matter’ and other basic configurations, I suggest that following the path it sets will be the preferred choice for a rational thinker.
In this sense, a 'rational thinker' is one who seeks logical advances that employ no help from a 'superpower'.
In support of my view, I make the following points:
1. This first point is absolutely fundamental. The Universe is composed of the material we call ‘Matter’.
2. Matter can be neither created nor destroyed. There is nowhere for Matter to come from or ‘disappear’ into.
3. On this point, if you fantasise some other place, you face only more problems! Where is this other place? How does the Matter become destroyed? How then does it get fed into that ‘other place’? But - It still hasn't ‘disappeared'. It lives on in some invented ‘other place’!
So - even in fantasy - this bit of Matter is neither destroyed nor disappeared. Even the ancient Greeks knew this.
4. Eternity: Quite a few people have a problem with this as an understandable idea. The idea has been around for thousands of years. The religious have always claimed eternity for their God. So, if God is eternal, why has he delayed (near eternally!) creating the Universe for so long? If he has existed forever previously and - the pundits claim our Universe is only 13-15 billion years old - and surely ‘his’ Universe would be perfectly formed in every way.
Here I need to make the point that, as an atheist, I maintain that the Universe is indeed a perfect place, which is why everything works so well.
We should now (unless religious) be at least in agreement that Matter is indestructible and therefore eternal.
That being so, and as the Universe is composed of Matter, it also is, therefore, indestructible, so it too must be eternal. Case proved – in Spades!
It really makes little difference what machinations you may choose to 'explain’ its existence, you can never get rid of it!
Some may perhaps say “Ah! But you never know! Maybe there’s something out there we know nothing of, that can do all these things that presently are impossible for us to even conceive.”
On this basis, of what if?, they will doubtless consider something like the Big Bang. If they do – there’s a problem!
Where did the Big Bang come from? (Refer here back to the indestructibility of Matter, Eternity etc.)
Whether you choose some sort of multi universe scenario, or stick as I do, with the one we’ve got, the whole thing is (eternally) pretty well the same story over and over, an endless roundabout. ETERNITY!
5. This conclusion, viewed now (by me) as a certainty, indicates that no superpower has any useful place in the Universe nor is it needed. Considering it at all, from a research angle is a complete waste of time. as it leads nowhere other than to yet another cosmological gum tree!
These considerations make a nonsense of gods etc., exposing these superstitions for what they are – superstition.
6. This allows us to consider ideas in a rational and logical manner. The Big Bang proposes that our present Universe manifested itself, theoretically, from ‘another outside universe’ that was able to invest all the Matter necessary to constitute our present Universe into a miniscule point called a Singularity. No information as to how this could be achieved is available! What led early 20th century astronomers into this fairyland was that having only recently (c.1915ish) discovered the Universe, they saw a red light emanating from the most distant stars. They designated this as ‘redshift’ and interpreted it as evidence that these stars were receding from us at speeds only exceeded by light itself. On this basis, they ‘concluded’ that the universe is expanding. If so, it must earlier have been smaller. Here enters the Singularity. Eventually, they decided that they could only ‘suppose’ a force capable of expanding the Singularity at such speed, so they did!
7. There is no definite evidence that the Universe is expanding. The meaning of Redshift is strongly disputed. I will cover this in a further post.The world renowned Astronomer Royal, Sir Fred Hoyle denounced the expanding Universe in a radio broadcast in the 1940’s and sneeringly called the whole idea the Big Bang! He later introduced an alternative idea he named as the Steady State. Unfortunately, he became mentally unwell and could not handle the stress he was subject to.
8. It is a shame (for me) that space on this site limits the length and breadth of my case which will later include web references that further support the case against the shoddy ‘science’ that presents supposition, unsupported by real evidence, as proven fact. Outrageous abuse of position and authority. The underlying motive force is (of course) money and professional position in a greedy world.

The essence of this forum is discussion. You have addressed your latest post to me, and I agree with much of what you say, but you have completely ignored my response to your previous post! Perhaps you missed it, and so forgive me if I repeat some of the points I put to you last time. Let’s tackle one issue at a time, and then we can move on.
reblak: It has absolutely nothing to do with faith – in the religious sense. For an atheist, faith means that, in the absence of absolute proof, we believe that the ideologies we accept, will indeed eventually lead to that absolute confirmation. […]
dhw: You believe that your ideology is correct. So does a theist. Your irreligious faith is that life is the product of an impersonal, unconscious force.
reblak: I do not see any problem with “amazing acts of creativity”. […]
dhw: This is where the alarm bells ring for me, because I do have a problem with “amazing acts of creativity”. While adhering to my agnosticism for very different reasons, I am acutely aware of and mystified by the complexities of living things. However, I also accept the following:
reblak: So, the laws of physics determine the outcome of atomic activities. Let’s me be clear on this. ALL physical actions are the result of the engagement of atomic activity. Molecules, cells etc are complex structures and are themselves affected and altered either by the acquisition of atoms or other biological ‘structures’ created by simple atomic conjunction. Unless you favour some God or other, what other possible manner of creation can there be?
dhw: The fact that all organisms are composed of tiny pieces added to and interacting with one another does not help me to understand how they are able to reproduce, to evolve, to acquire consciousness or, in our case, an extreme form of self-awareness. Even we, with our extraordinary intelligence, have so far been unable to put atoms together and create a living being that combines all these attributes. If we do one day succeed, that will hardly prove that an intelligent mind is not needed! And this leads to your next point:
reblak: Mother Nature is not subject to any other kind of influence.Therefore, (surely ) any actions these forces of nature engage in must be automatic. If you don’t accept this you are obliged to call on some magical power or some enormously powerful natural intelligence.
Absolutely right. If Nature is unconscious and automatic and Nature produced life, then the complexities of life have been produced unconsciously and automatically. But that is your faith. And if someone rejects your faith, he must believe in some kind of God. And that will be his faith. See my summary below.
reblak: It is of no extra importance whether a single celled ‘being’ or the final addition to the most complex structure in a human brain is being formed, only the simplest possible (at this stage) atomic/molecular ‘addition’ can be made.
Yes, the process entails the addition of atoms/molecules, but the fact that you believe the process is unconscious and automatic is totally separate from the fact that complexity arises out of additions.
reblak: I don’t see any rational alternative.
To sum it up: there are two possibilities (I’ll ignore my own panpsychist alternative). 1. The complexities of life came about through an unconscious (natural) process of combining atoms. But even we highly intelligent humans are not yet able to understand or reproduce this process, and if we could, that would be the result of genius-scale intelligence and not of unconscious natural processes. Belief in the creative genius of unconsciousness requires faith. 2. The complexities of life came about through a conscious mind combining atoms. But belief in an unseen, sourceless conscious mind so vast and powerful that it can create a universe etc. etc. (I needn’t preach to an atheist) requires faith.
I see both possibilities as requiring irrational faith. That is why I remain an agnostic.

Well now – and there I was thinking my ‘explanation’ could hardly be clearer nor more factually supported! Like it or not, awareness - of some sort - comes with the package!
A faith - relying upon established fact may well be wrong - it cannot possibly be ‘irrational’!
To exist at all, life must be a composite of several elements. These must include reproduction and a measure of ‘contact’ control ('rules of engagement') that itself probably constitutes the most primitive possible level of awareness. There is nothing we know of that can explain how life came about. This ‘absence’ gives no credence to engaging some sort of magic (God) as being the solution. Magic simply begs the question.
By a process of simple atomic acquisition, much as in my H2O example – (evolution is an inherent feature of nature and includes inorganic materials), these basic facilities mark life as a survivor. That is, to me an ‘unarguable’ fact, though the actual process I have suggested is not! The fact is – however you choose to describe it - that this process is and must be an automatic function created either by Mother Nature – or maybe, like atomic energy, is a fundamental physical reality. I do not believe life fits in this idea (first mooted by Sir Fred Hoyle).
Here is where the formative processes of sensation began. I ‘know’ this because there’s simply no other rational conclusion. They must have a start and this was it. To create an offspring demands extra energy and materials, so whatever passes as food (probably sunlight) must be absorbed. These functions must also be part and parcel of initial life or it could not survive.
It seems certain that the first organisms were botanical sea-life. Initially a very simple floating being, individuals began, by making slightly different ‘additions’ to follow paths that each led to a different outcome.
Mobility, albeit limited to floating on currents, opened wide many doors and presented possibilities that had huge potential and happened to make sense of acquired ‘additions’. Many of these would lead nowhere, but eventually ...
These developments were entirely automatic at each and every stage. A false step was actually as likely as a progressive one and led nowhere. A false step results in death or stagnation. Along the way, an organism becomes complex and its different parts become partially independent in their property of acquisition, but only if their actions are acceptable under the 'rules of engagement'. Thus may be acquired some useless but ‘tolerable’ extra something. In this instance the useless ‘part’, simply by its presence in the scheme of things closes down or diverts energy away from a useful direction.
It is well established that observation can lead to conclusions that are later verified. Mendel’s work is a prime example. He conducted experiments to prove already formulated intellectual conclusions as well as improving his ability to correctly forecast actual complex results.
I maintain that in acts of comprehension, the final absolute certainty of the truth of a matter may not need (and may never get) a total confirmation. Analogy again: a nut on a thread can travel only in a circular motion and – automatically – cause either up or down movement along the thread. Unless a correct thread is available the function of the nut is restricted by its nature in pursuit of any other function.
It may not find one: it will atrophy or be discarded. We can know for certain only that at the end of the thread the nut will cease to turn, fall off, return or stop. If we can discover the reason for the existence of the nut and bolt, a correct conclusion may be drawn. Without positive information concerning the purpose of this mechanism, no useful conclusion can be drawn.
This example typifies the case. You may ask what prompted the existence of the nut and thread in the first place and which came first, etc. The answer is – neither!
First came a nebulous need by a newly acquired ‘addition’. Here may I remind you that atoms automatically attract others. This attraction is itself a basic lead to awareness! In attracting other atoms a foundation is created. This will attract any additions that are acceptable under the 'rules of engagement'. Each such addition will amend these rules and determine the limits of possible outcomes.
Almost certainly, ‘awareness’ at this level is an atomic/chemical effect. In my H2O example, this form of atomic awareness changes the individual structures to operate favourably with each other. Such engagement, entailing this new effect, is a form of awareness of their attachment. This is a new ‘state’ of being and this ‘effect’ is what will, eventually, allow a development into conscious awareness.
More follows.

Once again, I shall have to cherry-pick statements in order to explain why I have problems with your faith.
reblak: A faith - relying upon established fact may well be wrong - it cannot possibly be ‘irrational’!
All our explanations “rely on” established facts. The mechanisms of life are a factual starting point. David argues rationally that they are too complex to be the product of chance, and so he believes in a designer. However, there are rational objections to belief in a designer:
reblak: There is nothing we know of that can explain how life came about. This ‘absence’ gives no credence to engaging some sort of magic (God) as being the solution.
Agreed. But you don't have a rational explanation yourself. As you say, nobody does.
reblak: By a process of simple atomic acquisition, much as in my H2O example – (evolution is an inherent feature of nature and includes inorganic materials), these basic facilities mark life as a survivor. That is, to me an ‘unarguable’ fact, though the actual process I have suggested is not!
Of course it’s a fact that life survives. But that is not the problem. The problem is how life and its mechanisms originated, and if you truly (and I would say irrationally) believe that it is a matter of “simple atomic acquisition”, I challenge you with all the intellectual powers at your disposal to create from scratch a living being that can reproduce and evolve.
reblak: The fact is – however you choose to describe it - that this process is and must be an automatic function created either by Mother Nature – or maybe, like atomic energy, is a fundamental physical reality. I do not believe life fits in this idea (first mooted by Sir Fred Hoyle).
Again, once you dismiss the irrational idea of a conscious designing mind, you place your faith in the equally irrational idea of unconscious Mother Nature’s creative genius.
You go on to talk about the necessity of food for survival, first life occurring in the sea, and additions leading to different outcomes, by which I presume you mean the vast bush of species extant and extinct. No problem here.
reblak: These developments were entirely automatic at each and every stage.
You have now moved to the mechanics of evolution itself and abandoned the problem of the origin of life and its mechanisms, as if it’s enough to say we don’t know what it is and that proves it must be automatic. I agree that evolution proceeds by additions (increased complexity, as in totally new organs) and I would add rearrangements (as in adaptations, and in existing structures changing their function: e.g. fins to legs), but I see all these as being too varied and too complex to be "automatic". Each one seems to me to require some form of responsive, organizing intelligence, perhaps seated in the cell itself, which combines – as you say – with other living cells to create the vast variety. (Intelligence is not synonymous with success, of course. Hence extinctions.) However, even this hypothesis would not solve the mystery of the origin of the intelligent cell.
reblak: I maintain that in acts of comprehension, the final absolute certainty of the truth of a matter may not need (and may never get) a total confirmation.
Of course we can’t get absolute certainty, but both you and David have taken the leap of faith that enables you to ignore all the rational objections to your beliefs.
I don’t find your nut analogy as helpful as the generalizations it is meant to illustrate, so I will move onto those:
reblak: First came a nebulous need by a newly acquired ‘addition’.
In the context of evolution, the need is far from nebulous. The most immediate need is for survival in a particular environment, but I would argue that there is a built-in intelligence that also looks for improvement. That explains why life has moved beyond survival (bacteria have survived perfectly well from earliest times).
reblak: Here may I remind you that atoms automatically attract others. This attraction is itself a basic lead to awareness! In attracting other atoms a foundation is created.
The rest of this paragraph seems to me to echo the hypothesis I offered you in my response on Monday 17 July at 09.07 under “Reasons why ID must be considered”. I’ll repeat the relevant paragraph to save you the trouble of searching.
This brings us back to the problem of how organic life and intelligence arose from inorganic materials – a question nobody can answer. But instead of your “Mother Nature” or David’s God, one can perhaps speculate that even the simplest of materials also have a form of intelligence – far more rudimentary than that of organic cells, but nevertheless endowing them with the ability, as you say, to combine atoms with atoms and form new materials. This idea, as you probably know, is a form of panpsychism, which seems to be enjoying a bit of a revival. What it comes down to basically is life and consciousness evolving bottom up from its most rudimentary forms to its most sophisticated. Some forms of panpsychism are theistic – but one might just as well have faith in a zillion bottom-up evolving consciousnesses as in a single top-down creative consciousness that has existed for ever. I’ll stop here to see whether these ideas have any resonance with you.
And I’ll stop again in the hope of a direct response to all of the above.

I have ‘abandoned’ no enquiry, nor any field we have discussed. The necessarily limited space is still a problem for me. So I will cherry pick!
1) “...as if it’s enough to say we don’t know what it is and that proves it must be automatic...
For so long as the secret of life remains undiscovered, we can only surmise. No help is presently gained by appealing to logic (atheism), praying to a God or sitting (like Humpty Dumpty), precariously balanced on a wall (fence).
You call upon me to accept that my atheism is an irrational faith and therefore carries no greater authority than pretty well any other faith, in that all ‘faith’ is irrational. I am at a loss trying to make sense of this. It has hitherto been my understanding that any belief that results entirely logically from known facts is a rational belief, while beliefs not so founded may well be irrational.
I have no difficulty in viewing both my adoption of atheism and my belief in the absolute perfection of the universe as prime examples of rational belief (yes, yes, belief!) Both views employ only known facts in support of their proven efficacy in understanding and solving problems. To define them as irrational, simply because they cannot (yet) explain how life has appeared, or to disparage them as vehicles for rational thought seems itself irrational – In Spades!
Challenging me by asking me to show how life can be created, as if my inability to do so were some criterion of the value of my thoughts, of atheism, or some sort of proof that logical explanation is not possible, does not advance my understanding. This ‘failure’ has bedevilled all thinkers since time immemorial. Does that mean that the thoughts of many great and original minds are all irrational?
Atheism, by definition, proposes that in seeking to understand the workings of nature conclusions should be drawn on the basis of known fact. Religion relies entirely on some superpower whose behaviour cannot be properly understood by man. This mythology, lacking any physical explanation, endows the putative God with magical powers (ad nauseam) but excludes any questioning or proof. The Agnostic sees merit on both sides but is convinced by neither.
Dhw suggests that a degree of awareness may exist in cells. My view is similar, but I propose that all the cells inherit awareness from much earlier – i.e. day one!
In parallel with my realisation that evolution has progressed by the automatic process of accumulating only atoms that were compatible, came my understanding that this action of itself constituted subatomic awareness. Eventually, with an advancing biology, came chemical awareness. All organisms are chemically aware, but it seems only mobile life has conscious awareness.
David says that biology “Does not work by adding atoms.”
Sorry, David – nothing can form without this process. I respect your authority in explaining the complexities of cellular evolution, but in creating complex parts, previously formed bits and pieces (I am no biologist!) are required. I cover this by pointing out that the initial process becomes infinitely more complex over time. Even in highly advanced life forms, gradual change applies, refining additions.
A point is reached when DNA etc. has almost total control but can be influenced by external forces which can rearrange things so that a new species may be formed or cause dreadful damage. However, this is highly controversial and not being discussed here.
I entirely agree that the successful advances in biology require some measure of intelligent direction. This is provided, right from the outset by the nature of physics. As I have made so plain, there are a lot of things that can, or cannot happen when Mother Nature gets to work.
I do not attempt correct scientific wording in my posts. I don’t think it makes a jot of difference in understanding the logic that I suggest as a reasonable and rational way to understand that nature can, really and actually ‘do the business’ without the aid of some mysterious ‘supervisor’ poking his invisible, frankly unbelievable, nose in!
Mother Nature didn’t need it, so - just how does having ‘directed intelligence’ magically solve this problem? It doesn’t!

I will accept that you are not a biologist and from you general statements I see that you have no concept of the workings of organic chemistry. Organic molecules are not put together by adding one atom at a time. There are giant enzymes that literally force the reactions to occur. How the process of chance evolution was able to construct these amazing enzyme molecules made up of thousands of atoms (to use your terms) is on of the unanswered problems Darwinism cannot answer. They are very specific in the way the strings of amino aids are placed and in the proper folding of the overall molecule.
The physical chemistry of organic chemistry has nothing to do with forming living organisms with all the cooperating organic molecules. Can you quote an article for me to support your contention? I can quote several which refute your 'physics makes biology' concept. The reason no one can explain the start of life is bsecause the initial cell had to be highly complex when it started. Almost 70 years of origin of life research and is no further than when the research began.
reblak Mother Nature didn’t need it, so - just how does having ‘directed intelligence’ magically solve this problem? It doesn’t!
Your blanket statement about Mother Nature and magic requires as much faith as an atheist can muster.

Hello David: If I accept (for the purposes of discussion only) that God generated the spark of life, that leaves me with a few questions.
1) Was it life only or was it the whole shebang?
2) In ‘guided’ evolution is the guiding permanent or spasmodic? For example only in fine tuning the brain.
3) If you believe that God was the creator of all this, how did he/she/it do it?
4) If you accept evolution in its present form, do you agree that God, having made it, has no need to interfere at all? Surely it must be perfect.
5) Would that mean that since the very first moment of God’s creation, that the Universe - being wholly ‘His’ work, has been designed to advance only on a Darwinian ‘slowly, slowly’ basis?
6) Does it also mean that – being Almighty – God knows of and is accountable for the all suffering endured by billions of ’His’ creations over billions of years and latterly inflicted on mankind. I note in this concept that although lesser life has no ‘freewill’ ascribed to its behaviour, it parallels our own in merciless killing and self-first intentions.
7) Do you believe in ‘freewill’? If yes, can you explain how mankind can make decisions that are independent of the creator and yet would be already known to ‘Him’ before we are born! An Almighty must inevitably know and fully understand how his creations will think and behave, else he is not all-knowing nor Almighty. If He did not know, he would actually know little (if any) more than a human psychiatrist. Any need to defend 'His' choices suggests that 'His' powers are not ‘Almighty’!
8) Do you limit God’s power? If not 'His' powers are limitless. How do you explain why it has taken 3 or 4 billions of years to arrive at even the earliest proto-humanoid? Was he just arsing around, experimenting until he made a more correct, more finely tuned product – us?
If the Universe he created has experienced one, possibly more Big Bangs, this presents his work as incomplete, inaccurate and in need of total reconstruction! Doesn’t sound likely to me!
9) What actually was so wrong that it was necessary to use his magical powers to reinvent the whole thing?
10) Were I a believer, I would not so insult my God with such banal questions. Such a misfit could not possibly fill the role I would attribute to him if he were capable of making mistakes, let alone bodge ups. What is your position on this?
11) Where do you stand in relation to the criticism that there is no ‘evidence’ of the existence of God?
This next comment may answer Dhw rather than yourself.
One of you wrote that he could not see that atheism, of itself, proved that the Big Bang did not happen - well here’s the why and wherefore. If you accept atheism there can be no God, so - to exist - the Universe must be an unalterable entity, there being nothing ‘else’ to adjust it (other than fairy tales). If you accept the Big Bang, are you saying He may have been messing about with other Universes and we are resident in His latest version?
There can, logically, be no ‘other’ (Superpower) either! It would first be necessary for nature to ‘do the business’ without help. Even if you assume that an intelligence has been formed that can now ‘guide’ nature, it has no place because nature doesn’t need it, because for it to exist 'Mother Nature' must first have given life to Superman and all else!
You say that biology does its work without recourse to a need to engage atoms in its structure of advancing highly complex processes. You state that larger molecules force change upon smaller molecules thus creating a new composite which – of course – can and does produce good, bad, indifferent or fatal results.
Whilst that is true, it needs a closer look. All molecules get that way as the direct result of the earlier atomic changes, not by some conjuring trick.
No atom, no molecule gives way to arbitrary change by force. Only ‘sympathetic’ structures (which may turn out well or badly) will allow a conjunction.
I maintain that the construction of mankind, by 'Mother Nature', fills the gap between the 'natural' and the more complex i.e. artefacts.
Artefacts are things 'Mother Nature' makes by using her newish tool, mankind, to add an intelligence directed mover to her own unconscious, ceaseless efforts to improve outcomes – for she cannot stand still.
Matter is eternal and all possible outcomes are intrinsic in and of its being. Were that not so, nothing would exist. Consequently, ongoing nature cannot be stilled. Automatism is paramount, automatically producing unceasing activity – including us.
I was asked how I feel about LIGO and gravitational waves. There will be more on this. The problem rests in the interpretation of what was seen, much as in the drivel spoken about the so called Higgs thing, a black cat that wasn’t there - but they found it! It doesn’t begin to explain mass. An immensely costly posturing act that has wasted £illions and £illions and an ocean of time! This triviality has been virtually ignored since its acclaimed discovery.

Hello David: If I accept (for the purposes of discussion only) that God generated the spark of life, that leaves me with a few questions.
Hi John. You written so much I'll limit myself to your numbered questions.
1) Was it life only or was it the whole shebang?
Whole shebang.
2) In ‘guided’ evolution is the guiding permanent or spasmodic? For example only in fine tuning the brain.
All of evolution
3) If you believe that God was the creator of all this, how did he/she/it do it?
I have no idea
4) If you accept evolution in its present form, do you agree that God, having made it, has no need to interfere at all? Surely it must be perfect.
I do not accept that God is pure perfection
5) Would that mean that since the very first moment of God’s creation, that the Universe - being wholly ‘His’ work, has been designed to advance only on a Darwinian ‘slowly, slowly’ basis?
God obviously chose to evolve the universe and life.
6) Does it also mean that – being Almighty – God knows of and is accountable for the all suffering endured by billions of ’His’ creations over billions of years and latterly inflicted on mankind.
It's a tradeoff, when He gave us free will, He gave up control of us.
7) Do you believe in ‘freewill’? If yes, can you explain how mankind can make decisions that are independent of the creator and yet would be already known to ‘Him’ before we are born! An Almighty must inevitably know and fully understand how his creations will think and behave, else he is not all-knowing nor Almighty. If He did not know, he would actually know little (if any) more than a human psychiatrist. Any need to defend 'His' choices suggests that 'His' powers are not ‘Almighty’!
Yes, and I don't think He anticipates our actions.
8) Do you limit God’s power? If not 'His' powers are limitless. How do you explain why it has taken 3 or 4 billions of years to arrive at even the earliest proto-humanoid? Was he just arsing around, experimenting until he made a more correct, more finely tuned product – us?
He chose to evolve the universe and humans.
If the Universe he created has experienced one, possibly more Big Bangs, this presents his work as incomplete, inaccurate and in need of total reconstruction! Doesn’t sound likely to me!
We don't know if there was only one or more. It is possible if there were many, each is complete when humans appear.
9) What actually was so wrong that it was necessary to use his magical powers to reinvent the whole thing?
As above, perhaps not wrong.
10) Were I a believer, I would not so insult my God with such banal questions. Such a misfit could not possibly fill the role I would attribute to him if he were capable of making mistakes, let alone bodge ups. What is your position on this?
I am not a believer in the sense you imply. Religions say God is all-powerful, but all knowing in the present and the future may not be the case.
11) Where do you stand in relation to the criticism that there is no ‘evidence’ of the existence of God?
I think He is inferred by what we see in our created reality.
John: All molecules get that way as the direct result of the earlier atomic changes, not by some conjuring trick. No atom, no molecule gives way to arbitrary change by force. Only ‘sympathetic’ structures (which may turn out well or badly) will allow a conjunction.
You are confusing the way atoms make molecules. Only molecules do the work of life. Atoms are just building blocks of molecules.
John: Matter is eternal and all possible outcomes are intrinsic in and of its being. Were that not so, nothing would exist.
All matter is a form of energy. They are interchangeable and eternal.

Thank you, David. I think ambivalent best describes your religious belief. I won’t quarrel over your answers because by now you will have heard it all before.
What surprised me is your willingness to imagine limitations to God’s powers. This means you are not bound by any particular formal theism but are your ‘own man’ on these matters. I applaud your judgment.
Perhaps you can advise me as to why you have such a reserved view of His powers. At one point you say, “All matter is a form of energy. They are interchangeable and eternal.”
If that means that, post God’s work, the universe can ‘do’ everything, we are in agreement except perhaps in defining the nature of matter. So the term ‘Energy’ is perfectly acceptable to me. It also allows that - under His supervision - nature has been granted the ability to generate life!
This implies that the finished state of the universe is as good as He could make it. Not much point in creating an imperfect universe that is eternal!
How can you see a limit to an intelligence that created an entire Universe complete with its phenomenal integral powers and ‘built in’ evolution?
As you know, I most adamantly believe that the universe is absolutely perfect. This automatically rules in the propagation of life and rejects unnecessary (and impossible) revision.
My own conviction is reinforced by a list of published mathematical, observational and experimental works which show why this is so. All are on the net (eg: The Electric Universe etc.)
I see an increasing flood of agreement that (as I maintain) awareness is ‘there’ from the kick-off, but no process is suggested. Here I remain ahead of the field!
It appears in our discussion of biology and atoms that my view may not be quite understood. My premise is that - initially – the process of building any entity can be achieved by only the very simplest of steps, literally one at a time. The initial formation seems likely to take a relatively long time, the 'rules of engagement' being quite primitive at that point.
The paths open will be virtually endless in number and will remain so, even after allowing for the continuing automatic limitation of those paths by new 'rules of engagement' created when accepting more conjoining atoms (later, molecules etc.) This development will allow a huge and slightly more complex range of ‘home made’ acceptable possibilities to become available.
Only very limited 'rules of engagement' will exist at first, consequently, nothing very complex can arise at an early stage of development. When a sufficient complexity is achieved then the 'rules of engagement' will foster a measure of parallel development by parts of the structure. That means that together with the main structural control, there are semi independent 'rules of engagement' that allow the (now) organism to grow its structures in parallel.
This will allow molecules, then cells to gain in function but each will still require access to additional atoms in erecting ‘improvements’ – they don’t come complete. How these ‘additions’ are added is probably by extraction from food and other forces that are capable of penetrating the body. Either way, it is not a ‘closed shop’.
Eventually, a true complexity is formed and the path of an evolution is laid.
My principal purpose is to show that the myriad possibilities of evolution live within the compass afforded to 'Mother Nature' by the structure and nature of the material Universe.
It is as if the Universe is an encyclopedia. Under every heading is a list of atoms that - strung together - make a particular structure that when completed may be not simply a fish, but a particular type. Other pages would list the needs for other fish, animals and so on – a rather big book!
What I am saying is that there is available, a potential route for the evolution of a successful organism. Once entered upon, whether for good or ill, life or death, the process must proceed along paths set by the conjunctions of underlying atomic processes. One way to think of this is a very long, very winding road with endless turnings at each side. These side roads also harbour endless side roads ad-Infinitum!
So - in understanding my proposition - the true mechanics of what does what and when it does it, is I think, intensely interesting, but immaterial here.
My purpose is basic. I wish to bridge the yawning gap between Dawkins pathetic and silly idea that pure luck, in the face of absolutely incredible odds, has fathered (along with 'Mother Nature'!) our wonderful Universe and contrast it with my own simple and logical tale of an automatic, but not quite blind, driven evolution.
It is, to me, obvious that just because we cannot ‘explain’ life yet, casting 'Mother Nature' as having been ‘lucky’ is, to say the least, improbable as she doesn’t do chance or arithmetic. The Universe has produced the idea of arithmetic, but arithmetic cannot produce, alter or negate the Universe.
'Mother Nature' works with what is, not what might be.

My comment about energy means nothing of the sort about a natural ability to create life. Matter is energy. Think if atom bombs, simply uranium releasing energy inside it. As for God, religions make all sorts of assumptions about Him, which I do not know are true.
John: This implies that the finished state of the universe is as good as He could make it. Not much point in creating an imperfect universe that is eternal!
Energy is eternal. The universe appeared 13.78 billion years ago from energy.

The initial formation seems likely to take a relatively long time, the 'rules of engagement' being quite primitive at that point.
I don't agree. Anything which is being built to have a purpose (in this case life) must have a visualization of the result in order to propose and design a plan of formation. Atoms do nothing but come together to make molecules. Two hydrogen atoms are joined to make the gas.
John: This will allow molecules, then cells to gain in function but each will still require access to additional atoms in erecting ‘improvements’ – they don’t come complete. How these ‘additions’ are added is probably by extraction from food and other forces that are capable of penetrating the body. Either way, it is not a ‘closed shop’.
I don't think you understand organic chemistry. Molecules that make life are very large and will not react together to make a new molecule product unless driven by an activating enzyme, which is a separate giant specially formed protein molecule that forces the two molecules to join.
Eventually, a true complexity is formed and the path of an evolution is laid.John: It is as if the Universe is an encyclopedia. Under every heading is a list of atoms that - strung together - make a particular structure that when completed may be not simply a fish, but a particular type.

It is accepted by many researchers that evolution runs on supplied information.

I have to agree with you that chance did not produce evolution and the amazing bush of life topped by humans with their amazing brains.
John: It is, to me, obvious that just because we cannot ‘explain’ life yet, casting 'Mother Nature' as having been ‘lucky’ is, to say the least, improbable as she doesn’t do chance or arithmetic.

You imply that the natural structure of the universe allows for life to develop, I assume automatically. Obviously I strongly disagree, unless you come around to the concept that the parallel image of your idea is God directing everything in the background.

I am NOT saying that atheism is an irrational faith. Atheism is simply rejection of belief in God. (As an agnostic, I neither accept nor reject the belief.) Atheism is not a faith at all. But like most atheists I know, you go beyond rejecting belief in God, which takes us to the secret of life. Yes, we can only surmise. We are not talking about “help” but about belief. In my view, faith is strong belief in something without proof, i.e. NOT resulting “entirely logically from known facts”. That is why I think belief in an unproven, sourceless, omniscient being can be called irrational faith. You confirmed your belief that “living beings can be produced by an impersonal and unconscious force which works automatically”.

I prefer to call atheism the rejection of a belief rather than a belief (see above), but that's not the point here. I agree that rejection is rational. I do not agree that belief in the creative powers of an unconscious force is rational. I still have no idea what you mean by the “absolute perfection” of the universe. If your Mother Nature were to drop a giant asteroid on our Mother Earth, killing me and a few billion others,I'm afraid my dying words would not be “I believe in the absolute perfection of the universe”, but since I don’t know your criteria I really don’t see your point. It certainly has nothing to do with theism or atheism.
Reblak: Challenging me by asking me to show how life can be created, as if my inability to do so were some criterion of the value of my thoughts, of atheism, or some sort of proof that logical explanation is not possible, does not advance my understanding.[...]
Your understanding of what? Of course my challenge won’t advance your understanding of how life came into existence. Your telling me you believe it arose through unconscious automatic processes won’t advance my understanding either. That does not devalue your thoughts on other subjects. Please, please do not take one disagreement to indicate dismissal of all your thoughts! On the contrary, I share your scepticism concerning the Big Bang (but regard this as irrelevant to theism versus atheism), and as regards your next comment (which contradicts your earlier characterization of “Mother Nature”) I had already suggested something similar in my reply to you on 17 July under "Reasons why ID must be considered"(not an apt heading for your debut on this forum!) but you never responded:
Reblak: Dhw suggests that a degree of awareness may exist in cells. My view is similar, but I propose that all the cells inherit awareness from much earlier – i.e. day one!
Dhw: (July 17 @ 09.07): "This brings us back to the problem of how organic life and intelligence arose from inorganic materials – a question nobody can answer. But instead of your “Mother Nature” or David’s God, one can perhaps speculate that even the simplest of materials also have a form of intelligence – far more rudimentary than that of organic cells, but nevertheless endowing them with the ability, as you say, to combine atoms with atoms and form new materials. This idea, as you probably know, is a form of panpsychism, which seems to be enjoying a bit of a revival. What it comes down to basically is life and consciousness evolving bottom up from its most rudimentary forms to its most sophisticated. Some forms of panpsychism are theistic – but one might just as well have faith in a zillion bottom-up evolving consciousnesses as in a single top-down creative consciousness that has existed for ever. I’ll stop here to see whether these ideas have any resonance with you."
I’m delighted to have at least a degree of support for this hypothesis, though I should add that I do not regard it as any more fact-based (rational) than the God hypothesis or the hypothesis that life originated automatically via an impersonal, unconscious force called Mother Nature.
Cosmology: Latest theories of everything
by BBella , Sunday, July 30, 2017, 22:10 (2672 days ago) @ John Kalber
It seems to me, not surprisingly perhaps, that atheism presents an unambiguous view of nature. Together with the extension of its logic in considering the state of ‘matter’ and other basic configurations, I suggest that following the path it sets will be the preferred choice for a rational thinker.
In this sense, a 'rational thinker' is one who seeks logical advances that employ no help from a 'superpower'.In support of my view, I make the following points:
1. This first point is absolutely fundamental. The Universe is composed of the material we call ‘Matter’.
2. Matter can be neither created nor destroyed. There is nowhere for Matter to come from or ‘disappear’ into.
3. On this point, if you fantasise some other place, you face only more problems! Where is this other place? How does the Matter become destroyed? How then does it get fed into that ‘other place’? But - It still hasn't ‘disappeared'. It lives on in some invented ‘other place’!
So - even in fantasy - this bit of Matter is neither destroyed nor disappeared. Even the ancient Greeks knew this.
4. Eternity: Quite a few people have a problem with this as an understandable idea. The idea has been around for thousands of years. The religious have always claimed eternity for their God. So, if God is eternal, why has he delayed (near eternally!) creating the Universe for so long? If he has existed forever previously and - the pundits claim our Universe is only 13-15 billion years old - and surely ‘his’ Universe would be perfectly formed in every way.
Here I need to make the point that, as an atheist, I maintain that the Universe is indeed a perfect place, which is why everything works so well.
We should now (unless religious) be at least in agreement that Matter is indestructible and therefore eternal.
That being so, and as the Universe is composed of Matter, it also is, therefore, indestructible, so it too must be eternal. Case proved – in Spades!
It really makes little difference what machinations you may choose to 'explain’ its existence, you can never get rid of it!
Some may perhaps say “Ah! But you never know! Maybe there’s something out there we know nothing of, that can do all these things that presently are impossible for us to even conceive.”
On this basis, of what if?, they will doubtless consider something like the Big Bang. If they do – there’s a problem!
Where did the Big Bang come from? (Refer here back to the indestructibility of Matter, Eternity etc.)
Whether you choose some sort of multi universe scenario, or stick as I do, with the one we’ve got, the whole thing is (eternally) pretty well the same story over and over, an endless roundabout. ETERNITY!5. This conclusion, viewed now (by me) as a certainty, indicates that no superpower has any useful place in the Universe nor is it needed. Considering it at all, from a research angle is a complete waste of time. as it leads nowhere other than to yet another cosmological gum tree!
These considerations make a nonsense of gods etc., exposing these superstitions for what they are – superstition.
6. This allows us to consider ideas in a rational and logical manner. The Big Bang proposes that our present Universe manifested itself, theoretically, from ‘another outside universe’ that was able to invest all the Matter necessary to constitute our present Universe into a miniscule point called a Singularity. No information as to how this could be achieved is available! What led early 20th century astronomers into this fairyland was that having only recently (c.1915ish) discovered the Universe, they saw a red light emanating from the most distant stars. They designated this as ‘redshift’ and interpreted it as evidence that these stars were receding from us at speeds only exceeded by light itself. On this basis, they ‘concluded’ that the universe is expanding. If so, it must earlier have been smaller. Here enters the Singularity. Eventually, they decided that they could only ‘suppose’ a force capable of expanding the Singularity at such speed, so they did!
7. There is no definite evidence that the Universe is expanding. The meaning of Redshift is strongly disputed. I will cover this in a further post.The world renowned Astronomer Royal, Sir Fred Hoyle denounced the expanding Universe in a radio broadcast in the 1940’s and sneeringly called the whole idea the Big Bang! He later introduced an alternative idea he named as the Steady State. Unfortunately, he became mentally unwell and could not handle the stress he was subject to.
8. It is a shame (for me) that space on this site limits the length and breadth of my case which will later include web references that further support the case against the shoddy ‘science’ that presents supposition, unsupported by real evidence, as proven fact. Outrageous abuse of position and authority. The underlying motive force is (of course) money and professional position in a greedy world.
Thanks for taking the time, reblak, to share and give us your view, much of which fits in with my own, though I do have thoughts on a few points you make, but hope those points may come back around or be addressed or clarified sooner or later as you continue to share - or I may bring them back around later when I can put my thoughts into more than just a few words at a time.
Cosmology: Inflation theory under attack
by David Turell , Wednesday, August 02, 2017, 00:54 (2670 days ago) @ BBella
There are problems with the theory:
https://evolutionnews.org/2017/08/cosmic-inflation-theory-loses-hangups-about-scientifi...
"Two features of our universe puzzle cosmologists: One is the horizon problem: The universe looks the same in all directions and the cosmic microwave background radiation is about the same temperature everywhere. As String Theory for Dummies puts it, “This really shouldn’t be the case, if you think about it more carefully.” Assuming that current measurements are correct, the radiation must have exceeded the speed of light if it really communicated in this way, but that is forbidden by the standard Big Bang model of the universe.
"Then there is the “flatness problem”: “The matter density and expansion rate of the universe appear to be nearly perfectly balanced, even 14 billion years later when minor variations should have grown drastically” (Dummies). Inconveniently, the apparent 1:10^66 fine-tuning of the Big Bang, of which horizon and flatness are features, is frequently used as an argument for the existence of God.
"Cosmic inflation theory, first proposed by Alan Guth in 1981, modified the Big Bang theory (the Standard Model) by proposing that the universe, instead of unfolding at a steady pace, expanded rapidly shortly after it was created, which could account for apparent fine-tuning.
***
"The “bouncing cosmology” was initially proposed by Steinhardt and others in 2001, and fleshed out in 2014. When BICEPS II failed to find evidence of inflation in 2014, Michael Slezak crowed at New Scientist “Inflation is dead, long live inflation! The very results hailed this year as demonstrating a consequence of inflationary models of the universe — and therefore pointing to the existence of multiverses – now seem to do the exact opposite. If the results can be trusted at all, they now suggest inflation is wrong, raising the possibility of cyclic universes that existed before the big bang.” Some were willing to trade the shadowy multiverse for (at least) one other (past) universe, however modest.
"An exchange of letters followed, between the three authors (IS&L) and 33 cosmologists who defended early rapid inflation, among whom readers may recall Alan H. Guth, Sean Carroll, Andrei D. Linde, Stephen Hawking, Lawrence Krauss, Martin Rees, George F. Smoot III, Leonard Susskind, Alexander Vilenkin, and Steven Weinberg.
"The 33 signatories pointed to the fact that 14,000 papers that use the word “inflation” or “inflationary” in their titles or abstracts have been written by 9,000 scientists. They were stung by the accusation that inflationary cosmology “cannot be evaluated using the scientific method” and that some proponents have proposed discarding a defining property of science: “empirical testability.” They retort that “it has been subjected to a significant number of tests and so far has passed every one.” That would settle the matter except that, as they admit, “Inflation is not a unique theory but rather a class of models based on similar principles.” Empirical science, they concluded with a flourish, “is alive and well!”
***
"IS&L replied that “The claim that inflation has been confirmed refers to the outdated theory before we understood its fundamental problems,” including the fact that generic inflation leads to eternal inflation and, in consequence, a multiverse: “And if inflation produces a multiverse in which, to quote a previous statement from one of the responding authors (Guth), ‘anything that can happen will happen’—it makes no sense whatsoever to talk about predictions. Unlike the Standard Model, even after fixing all the parameters, any inflationary model gives an infinite diversity of outcomes with none preferred over any other. This makes inflation immune from any observational test.”
***
"All parties to the dispute assume, as a metaphysical stance, that science cannot address the possibility that the universe shows evidence of design. Even if design turns out to be the best explanation and the most fruitful for progress, it cannot be accepted, as a matter of first principles."
Comment: Inflation explains much of why the universe looks as it does, but not without problems. A cyclic universe gets rid of the origin problem but keeps the Big Bang. It also gets rid of the multiverse. A cyclic universe doesn't get rid of a first cause.

Reblak has mentioned the red shift problem too, and perhaps he will explain this in more detail.
On this forum we have repeatedly discussed the unanswerable question of what preceded the Big Bang if the Big Bang ever happened. The concept of eternal energy and matter as first cause would allow for any number of universes before this one, or for this one itself being eternal and constantly changing.
Cosmology: standard universe model confirmed
by David Turell , Thursday, August 03, 2017, 19:03 (2668 days ago) @ dhw
A new study of new and old galaxies using dark matter evidence confirms the standard model of the universe and analysis of its aging:
https://phys.org/news/2017-08-standard-universe-precise-dark-energy.html
"Astrophysicists have a fairly accurate understanding of how the universe ages: That's the conclusion of new results from the Dark Energy Survey (DES), a large international science collaboration, including researchers from the Department of Energy's SLAC National Accelerator Laboratory, that put models of cosmic structure formation and evolution to the most precise test yet.
"The survey's researchers analyzed light from 26 million galaxies to study how structures in the universe have changed over the past 7 billion years - half the age of the universe. The data were taken with the DECam, a 570-megapixel camera attached to the 4-meter Victor M. Blanco Telescope at the Cerro Tololo Inter-American Observatory in Chile.
***
"KIPAC faculty member Risa Wechsler, a founding member of DES, said, "For the first time, the precision of key cosmological parameters coming out of a galaxy survey is comparable to the ones derived from measurements of the cosmic microwave background. This allows us to test our models independently and combine both approaches to obtain parameter values with unprecedented precision."
"The standard model of cosmology, called Lambda-CDM, includes two key ingredients. Cold dark matter (CDM), an invisible form of matter that is five times more prevalent than regular matter, clumps together and is at the heart of the formation of structures such as galaxies and galaxy clusters. Lambda, the cosmological constant, describes the accelerated expansion of the universe, driven by an unknown force referred to as dark energy.
"Astrophysicists need precise tests of the model because its ingredients are not completely certain. Dark matter has never been directly detected. Dark energy is even more mysterious, and it's not known whether it actually is a constant or changes over time.
"DES has now succeeded in carrying out such a precision test. The scientists used the fact that images of faraway galaxies get slightly distorted by the gravity of galaxies in the foreground - an effect known as weak gravitational lensing. This analysis led to the largest map ever constructed for the distribution of mass - both regular and dark matter - in the universe, as well as its evolution over time.
"'Within an error bar of less than 5 percent, the combined Planck and DES results are consistent with Lambda-CDM," Wechsler said. "This also means that, so far, we don't need anything but a constant form of dark energy to describe the expansion history of the universe."
***
"Another key to the creation of the mass distribution map was to accurately determine the distances to the observed galaxies - information that is usually derived from independent surveys that analyze the properties of light coming from those objects or from exploding stars.
"'We've shown that we can use the color of certain red galaxies - red is the color they would have if you were right in front of them - to determine how far they are away," said SLAC staff scientist Eli Rykoff, who had a leading role in this part of the analysis. "It turns out that if we map where these red galaxies are in the sky, we can use them to calibrate the distances of the lenses and background galaxies used in the study.'" (my bold)
Comment: Note the bold. The study uses the red shift which reblak (John) thinks is wrong. Most cosmologists, however, fell they have solidified the standard model of the universe. I agree.

The problem with red-shift is that it assumes a constant, uniform speed of light, when experimentation shows it can be bent, its path manipulated by gravity, which would by necessity alter travel time.
The math is pretty hairy, but there is some weirdness in the logic. If the CMB is the 'outer elipse' of our universe, it is moving faster than we are because it is further along in its expansion which makes it travel further faster.
- Our universe is accelerating AND expanding, which means that older objects are traveling FASTER than we are.
- Not only do you have to know where we are in relation to the 'origin', but also where we are relative to the expansion/acceleration cycle of the universe as a whole.
- What's more you have to KNOW how fast the outside edges are ACTUALLY moving. (Otherwise you can't know how fast the universe is actually expanding.)
- We do not KNOW the origin point of the universe, we assume it.
- We do not KNOW our position relative to the origin, because we do not know the origin.
- We can not accurately measure WHERE the CMB is, because we do not have a confirmed point of Origin, only an assumption.
- If the radiation from the CMB is what we are detecting, how fast is that radiation travelling by the time it reaches us?
- What is the time shift(think doppler effect) on the light because of the fact that it's source is moving away from us at an ever increasing and unknowable speed?
- Add to it that the path of light can be 'bent' around one or more objects and gravitational wells, and it no longer can be seen as a straight line distance.
- If we do not not know WHAT objects altered its path, or how far it deviated from it's original path, we can not assume a fixed point of origin. If we can not assume a fixed point of origin, we can not determine relative speeds etc, blah blah.
Basically, that theory is still a bunch of "We don't know but we assume that.,..." and "Because we assume our initial assumptions are true, we assume that this information we have confirms our initial assumptions, none of which can, at this point be proven."

Thank you for a great exposition of the problems. A Hubble constant for expansion has been calculated and re-corrected several times. The universe and its parts are expanding. It is not static.

Tony has gone to a great deal of trouble to explain the possible scientific flaws in the whole theory, for which he has my thanks. I’m sure reblak will support this scientific debunking, and reblak is an atheist. But of course Tony thinks God did whatever happened – he is a theist – and of course we don’t know how everything came about, and of course you can believe in God whatever anybody else’s theory may be. In the great quest for knowledge – one of the most admirable manifestations of the indomitable human spirit – we come up with all kinds of nebulous theories to explain the things we do not understand: dark matter, dark energy, strings, multiverses, Mother Nature, God…But giving them a name doesn’t make them real. A quote from Dawkins has stuck firmly in my mind as a wonderful example of blinkered faith: “If there is something that appears to lie beyond the natural world as it is now imperfectly understood, we [= atheists] hope eventually to understand it and embrace it within the natural.” (The God Delusion, p. 14).

Absolutely not. My alternative to your eternal pure energy inexplicably conscious of itself is eternal energy and matter forever transmuting themselves and inexplicably evolving consciousness.

DAVID's comment: Inflation explains much of why the universe looks as it does, but not without problems. A cyclic universe gets rid of the origin problem but keeps the Big Bang. It also gets rid of the multiverse. A cyclic universe doesn't get rid of a first cause.
Reblak has mentioned the redshift problem too, and perhaps he will explain this in more detail.
On this forum, we have repeatedly discussed the unanswerable question of what preceded the Big Bang if the Big Bang ever happened. The concept of eternal energy and matter as first cause would allow for any number of universes before this one, or for this one itself being eternal and constantly changing.
A cyclic Universe may well be a good suggestion and reflects somewhat my own view. How this cycle works is totally unknown. Proponents of other multiple universe ideas totally fail to accept that as Matter is unconscious it must work in accord with existing intrinsic universal physical law.
What is knowable is that there is no ‘first cause’. Eternity doesn’t include first causes! Everything has always existed, on and off, at different times and circumstances. In our perfect Universe, conditions at any point denote outcomes. Its inherent capacity allows any and every possible variation over time.
What it may include is an ongoing process of collapse and regeneration. That behaviour may possibly occur as a result of widespread supernovas. We may never know the definite truth. Such regeneration may entail a ‘rolling’ effect that is always afoot from place to place throughout the Universe. However, there can be no change in the actual makeup. The ‘laws’ have no capacity for change. An automatic process cannot change – it is immutable!
This process thereby totally precludes any pre-existing form of Universe. Such a view is a grossly misguided failure to understand that we have already a perfect Universe. Were it imperfect it would never have existed. This factor removes any possibility of any Big Bang or its attendant Black Holes and invisible Dark Fairies. Any re-formation absolutely must occur only within pre-exist [now also current] universal physical laws.
Automatic processes are part and parcel. To go on about the possibility of unknown and unknowable forces as real contenders to justify theoretically unprovable modern Big Bang cosmology is nothing short of a disgrace!
The concept of energy and Matter as somehow preceding itself [when possessing powers different from anything we can imagine] and ‘choosing’ everything we know of is utter nonsense. All Matter, all energy, is and can only be, integral to the whole.
Otherwise, how could energy exist? Sorry folks, imagination, magic or rubbish in rubbish out computer scenarios just don’t cut the mustard!
The question remains. Why do highly educated, intelligent scientists keep allowing their research to be influenced by what are ridiculous, utterly impossible, fairyland assumptions involving Big Bang theory, Dotty Dark Matter and Energy. Oh! I forgot, Multiple Universes!
Not one jot of actual proof has been advanced in support of these ideas. Instead, millions are spent creating scenarios where they might exist - without achieving anything other than well-off scientists!
To see why this so requires knowledge covering the machinations of the scientific hierarchy over the past century and longer. What now follows will shock the average reader and may be met with incredulity, even disbelief. I ask you to accept that the substance is accurate, though its interpretation [by me] reflects my own shocked and deeply resentful feelings with regard to the damage being done to the advancement of science.
The policy of the Royal Society still reflects the impact of the 24 years Pharaoh ideology residency of Sir Isaac Newton, a deeply religious, great man. His legacy has disallowed any known atheist access to this honour. Even the great Sir Fred Hoyle, the ‘Queen’s Astronomer’ was denied. It is a mistake to underestimate the ongoing power of this kind of influence.
It was around 1916 that it was discovered that the Milky Way was only a galaxy and not the entire Universe. Edwin Hubble suggested that distant reddish light [Redshift] might be interpreted as very high-speed motion away and could mean that the Universe is expanding.
Sadly, as in every ‘age’, the scientific establishment has twisted and turned [and lied] in an endeavour to resist new views.
So, the scientific leadership happily insisted this was proof, not possibility ¬- Hubble had proved it! This reinforced Newtonian ideology because it posited a beginning and allowed the notion of creation [i.e. God] so it was a socially acceptable explanation and considered a proven actuality – which it was not!

In 1937 Hubble delivered another such lecture. This time his view was different. He compared the two views and said that either could be right and more research was needed. He also said that redshift may represent an entirely new phenomenon.
No such research was made.
The assumption that redshift represents high-speed expansion became a mantra, requiring of students that it be acknowledged as fact [otherwise] no pass in examinations.
It was then reasoned that the Universe is expanding at colossal speed. This meant that it must originally have been very much smaller. But this didn’t work mathematically so it was ‘decided’ that the Universe had started out as Matter compressed into a tiny point called a Singularity. This was produced by a pre-existing Universe whose physics allowed this otherwise totally impossible compression.
Then, at some point, the Singularity expanded violently into a massive cloud of particles. After about millions of years, it started condensing into the Universe we now have and began expanding at colossal speed.
Sir Fred Hoyle, in a 1947 BBC radio broadcast jeeringly coined the phrase “Big Bang” in dismissing this totally unevidenced, damn silly idea! He proposed an alternative ‘Steady State’ solution that offered an eternal, endless Universe.]
Because of [principally] redshift, it was claimed that this must lead to these incredible conclusions!
Wishful thinking in Spades!
No evidence, let alone proof is required! These ‘ideas’, [for that is all they are!] proved unsustainable because the only force credited with galactic wide effect is gravity. This is the weakest natural force and is not up to the job! Therefore some mechanism was needed to intensify gravity!
Jules Verne steps up: “Got it! There must be Black Holes!” These [imaginary] areas of highly condensed Matter might produce the necessary. Then – oh dear – there was not enough Matter. 90% plus was missing! Jules Verne to the rescue once again. “There must be ‘Dark Matter. I name it so because you cannot see it or find it, but - it answers the call, so shut up about silly old proof!”
Oh dear again. It’s not enough. Up steps our saviour once more, “Not a problem. Dark Matter gives off Dark Energy! You cannot trace this so no-one can prove it isn’t there.” Together, these [imaginary] elements seemed to finally solve the problem but, it hasn’t.
So I, [and umpteen thousand others] are not content with ‘Jules Verne’ or ‘Alice in Wonderland’ solutions.
All these fantasies fade from view when true functioning physics are applied. These are detailed on the Electric Universe websites. They principally advocate the application of electricity and electromagnetism in explanation, no mystical powers needed.
Both ‘sides’ claim markedly conclusions drawn from the same telescopic observations.
The underlying difference is that the authors do not claim their views to be proven fact but provide a rational basis for understanding and further discovery. I am an E.U. fan.
The grounds for the Electric Universe theory were born in what is known as ‘The Velikovsky Affair’ that followed his 1950 publication of ‘Worlds in Collision’.
Velikovsky claimed [along with evidence supporting widespread mythology] that the planet Venus was ejected from Jupiter c.1500BC with amazing, Earth-shaking, near collisions with Earth. He presented new ideas that meant that the sciences of cosmology and geology were in dire need of revision.
The ‘Establishment’ went crazy, issuing hysterical complaints that Velikovsky was a fraud, another Von Daniken. They threatened to boycott his publisher, who was forced to sell off this million dollar goldmine to pacify its clientele.
All this shocking behaviour resulted in the immediate expulsion of any student who dared to raise his theories in discussion. I had personal experience of this belligerent attitude.
Velikovsky was the first to claim that Venus would be very hot [in opposition to then scientist ........who said that Venus was Earth-like.]. When a space capsule proved Velikovsky right and ......... completely wrong, this man said, insultingly “Give Enough monkeys typewriters and ...!”
How dare he? This, however, revealed the depth of enmity poisoning the anti-Velikovsky atmosphere.
All this because of a new and different viewpoint? Yes. But...
The real reason was that accepting his findings, as even just discussion points, would open wide closed doors, releasing suppressed information that would bring down highly paid international figures.
That could not be allowed. So afraid were they, no avenue of abuse was too much. This behaviour made Professor Alfred De Grazia write ‘The Velikovsky AffairUS: Scientism vs. Science’ detailing the whole scandal in 1967 – 256 pages!
Nowadays, we are being advised of amazing new discoveries that disclose in nearby galaxies proofs of the alternative scenario proposed by Velikovsky. Not a word about Velikovsky. No attribution whatever. These people have probably never even heard of him.

At root here is the continuing influence of Royal Society dogma. Both Hoyle and Velikovsky [the fathers of modern revolutionary cosmology] had ideas that are the basis of Electric Universe theory. On those grounds, the ‘establishment’ pour scorn upon their research and publications. They refuse even to debate the issues. If they should publicly do that they fear upsetting their professional and financial masters.
Millions in cash are involved – not least in U.S.government funding of NASA. Should the government be presented with doubts the anti lobby would easily succeed in jettisoning NASA and its expensive space research and its staff, possibly bankrupting huge, dependent companies.
Here it becomes even clearer why ‘top’ science prefers promoting a ‘status quo’ for establishment cosmology! The more mystical they can make it ...
I have neglected the ‘Redshift. It comes shortly.
“Heigh-ho ho Silver!” Oh no, it’s not Roy Rogers it’s Redshift!
Either way, it is, allegorically a bucking bronco!
As poor old Hubble’s ‘findings’ have been distorted to satisfy establishment wishes, it becomes desirable to present relevant material from his 1937 Royal Society lecture.
This lecture can be viewed by right-clicking: The Observational Approach to Cosmology
If necessary r/clk this link: https://ned.ipac.caltech.edu/level5/Sept04/Hubble/paper.pdf
The idea of an expanding universe was invented independently by the Russian scientist Alexander Friedmann and by the Belgian cosmologist Georges Lemaıtre, with their solutions of Einstein’s theory of general relativity applied to the cosmic fluid. Their pioneering papers on the subject were published in 1922 and 1924, as well as 1927 and 1931. The redshift: apparent magnitude (or distance) relation discovered by Edwin Hubble in 1929, fitted nicely the new theoretical picture. The so-called Hubble’s law was precisely the one predicted by both Friedmann’s and Lemaıtre’s models. It was immediately raised to the status of an “observational” discovery of the expanding universe.
This, of course, is not the case.
The idea of an expansion is, first of all, a theoretical idea — a strange “effect” in the earlier, empty de Sitter model. Hubble’s observations are consistent with the idea but are not necessarily a proof of it. Hubble himself was aware of this and sought all his life for the correct answer to the question posed by his discovery: What does cause redshifts? The two possibilities considered by him were the expanding relativistic models and the tired-light paradigm.
“... The features, however, include the phenomena of red-shifts whose significance is still uncertain. Alternative interpretations are possible, and, while they introduce only minor differences in the picture of the observable region, they lead to totally different conceptions of the universe itself.”...
“...The small volume of the universe is another strange and dubious conclusion. The familiar interpretation of red-shifts as velocity-shifts very seriously restricts not only the time scale, the age of the universe but the spatial dimensions as well. On the other hand, the alternative possible interpretation, that red-shifts are not velocity-shifts, avoids both difficulties and presents the observable region as an insignificant sample of a universe that extends indefinitely in space and in time...”
“...But the essential clue, the interpretation of redshifts, must still be unravelled. The former sense of certainty has faded and the clue stands forth as a problem for investigation. Larger telescopes may resolve the question, or theory may be revised to account for the new data. But with regard to relativistic cosmology in its present form, and the observations now available, the conclusion can be stated quite simply. Two pictures of the universe are sharply drawn. Observations, at the moment, seem to favour one picture, but they do not rule out the other. We seem to face, as once before in the days of Copernicus, a choice between a small, finite universe, and a universe indefinitely large plus a new principle of nature...”
Leaving aside subsequent observations [the proofs needed have not been found and for clarity of purpose, we need to understand the ‘Newton attitude’ prevailing at that time.
Hubble was totally unsure as to the verity of Redshift and was very upset by having his words and evidence being falsely presented as actual proof of either theory.
There is no proof by Hubble that Redshift denotes an expanding Universe.That theory should of course be the subject of research and debate but it is unpardonable that it is claimed as proven by Hubble – that is a deliberate lie. At some point he retracted that view but never found its way into ‘scientific’ circles. What a surprise! You may now see understand how such an ‘attitude’ together with absolutely huge financial implications can develop into a near criminal conspiracy, ruining peoples lives with, for the perpetrators, no escape plan.

Hubble is long dead. It seems 99%+ of all cosmologists accept the red sift as connoting an expanding universe. The supernova study of several years ago indicated the speed is even faster than thought.

David: How do you know our universe is perfect? It is certainly very dangerous to life, except where it seems protected on Earth.
This is easily dealt with. For something to be seen as imperfect requires a comparison. In a comparison, we may be able to select weak points. The Universe stands alone so cannot be ‘compared’. It has no faults as far as I can see. Being virtually automatic, it has no consciousness, beyond a measure of ‘direction’ generated in sub-atomic and chemical awareness in differing states of being. Until the advent of life, there could be no conscious awareness.
As the several levels of awareness demonstrated in nature are all there is, the inevitable outcome [in the case of life] must place the need for food and survival above all else.
That applies equally to mankind. Nature’s functions do not include exemption from danger, only some well-meaning, all powerful God could so manipulate natural events. Further evidence that He doesn’t exist.
Many animals are born with teeth and claws that are used to kill their prey. Learning the skills of hunting are mandatory. An example springs to mind: a kitten captures and plays with a mouse, enjoying its terrified attempts to escape until it finally kills it. Horror for mousie, hunt practice for the kitten.
What part does this murder play in suggesting that God set the rules? Surely no God would settle for a maximum of cruelty being inflicted on terrified, quite innocent victims.
It’s is all 'Mother Natures' work and this ‘behaviour’ is the only possible way. Only ‘blind’ nature would allow literally any form of life the chance of survival. It can’t avoid it.
David posits his God as the creator who uses evolution as the medium of creation. That surely means, leaving God to one side for a moment, that since its 'creation' there has been no need for God to intervene. He must have set the laws that guide nature in all its functions.
This leaves 'Mother Nature' appearing to be doing it unaided, but – for some, that is not so. They believe God implemented all the 'know how' at outset.
Nonetheless, David chooses to believe that his God is not actually all knowing, all powerful, nor absolutely perfect! That seems a fair representation of David's view.
This is, in my view, an unusual opinion. How can David know God has limitations? I bet my life he doesn't hear voices or see visions and is a sane, normal person. He adheres to the idea that God granted us free will and is therefore not responsible for mankind's often cruel behaviour. This presents [for him] an unusual degree of 'soul searching'.
I'm sure he believes this but - it is simply an idea - a way of defending his particular version of God from involvement in elements of human behaviour that are indefensible.
Critically, this does not exclude God from responsibility for the carnage wreaked upon the animal world. Almost all animal life spends a huge amount of time killing other creatures in the hunt for food or safely.
Neither does it account for the evolution of homo sapiens through a very long period of hominids. Was this God entertaining itself, mucking about with early such lifeforms for millions of years until hitting upon making us? Or was it 'Mother Nature' wending her tortuous, largely automatic way through a web of possibility [which is still in progress].
Almost all animal deaths are a terrifying, agonising and unavoidable experience that can include being eaten alive. Harshly cruel death by thirst and hunger is the fate thrust upon many humans [particularly coloured people - is God a racist?] as well as upon animals, fish etc. All these brutal realities can serve only to support an atheist view.
A rational approach to thinking of these things will end by accepting that these outcomes are simply the rule of 'Mother Nature’, exemplified in the well-known phrase, “Red in tooth and claw.” I can see no difference [in outcome] whether God exists or not.
David may be satisfied by resolving this endless terror with invented rationalization [such as freewill] in sustaining his belief. I am not!
That being so and as nature’s actions can be proven, whereas God’s [if any] cannot, there is no cause, beyond wishful thinking, to introduce any superpower. It is no good complaining that, in acts of nature, we are unable to identify the initial process of life so -“There must be a God and He makes life. Not nature.”
How the blazes can anyone know what a God, who never reveals himself, thinks, feels or does. Faith alone is not an answer. There must first be something demonstrably provable to have faith in!
So - it’s twaddle. All it means is that, for emotional convenience, by simply assuming God’s existence, we can attribute solutions we cannot otherwise find - to a mythical godhead that we invent and empower. Pure superstition – no evidence – just magic. Curiously, apply these assumptions of ‘arcane’ ability directly in favour of 'Mother Nature' and the problems disappear! Well – almost!

Reblak appears not to read my responses to his posts (which are a mixture of agreement and disagreement), but as his reply to David touches on many of the points I have also raised, I hope you'll both forgive me for sticking in my agnostic oar – sometimes for and sometimes against his arguments.
David: How do you know our universe is perfect? It is certainly very dangerous to life, except where it seems protected on Earth.
Reblak: This is easily dealt with. For something to be seen as imperfect requires a comparison. In a comparison, we may be able to select weak points. The Universe stands alone so cannot be ‘compared’. It has no faults as far as I can see.
“It has no faults as far as I can see” depends on your personal definition of perfection, imperfection and faults. You are quite right that there can be no comparison. That is why there is absolutely no point in imposing any of these concepts on it. I’ll repeat what I said in my earlier response: The universe is what it is and does what it does. That’s it.
Reblak: Being virtually automatic, it has no consciousness, beyond a measure of ‘direction’ generated in sub-atomic and chemical awareness in differing states of being. Until the advent of life, there could be no conscious awareness.
Here you have touched on another subject I have raised in my responses: panpsychism, and the crucial question is precisely the degree of awareness or consciousness (I am not talking of human self-awareness) that may or may not be present in all materials. Do you believe it is sufficient to put together all the components necessary for the enormously complex mechanisms of life, reproduction, and the capacity for evolution leading from bacteria to the human brain? Such belief requires ignorance of these complexities (which seems unlikely in someone as learned as yourself) or a mighty degree of faith.
Reblak: What part does this murder play in suggesting that God set the rules? Surely no God would settle for a maximum of cruelty being inflicted on terrified, quite innocent victims. It’s is all 'Mother Natures' work and this ‘behaviour’ is the only possible way. Only ‘blind’ nature would allow literally any form of life the chance of survival. It can’t avoid it.
Since you clearly find this “maximum of cruelty” as repugnant as I do, I wonder how you square it with your personal concept of a “perfect” universe.
Reblak: David posits his God as the creator who uses evolution as the medium of creation. That surely means, leaving God to one side for a moment, that since its 'creation' there has been no need for God to intervene. He must have set the laws that guide nature in all its functions.
This, as David says, is a deist interpretation of God, and provides a theistic explanation for all the cruelties, which I for one find perfectly logical. Once more, then, the question of whether he exists or not boils down not to his possible nature but to whether you have sufficient faith in what you call “sub-atomical and chemical awareness” to believe that it is capable of producing the mechanisms described above – a question which you consistently ignore. NB This is a major factor in my own agnosticism, since I do not have that faith.
Reblak: This leaves 'Mother Nature' appearing to be doing it unaided, but – for some, that is not so. They believe God implemented all the 'know how' at outset. Nonetheless, David chooses to believe that his God is not actually all knowing, all powerful, nor absolutely perfect! That seems a fair representation of David's view.
David has replied that his God may have limits. At other times he says his God is in total control. His view appears to change according to whatever objections are raised to his hypotheses.
Reblak: Neither does it account for the evolution of homo sapiens through a very long period of hominids. Was this God entertaining itself, mucking about with early such lifeforms for millions of years until hitting upon making us? Or was it 'Mother Nature' wending her tortuous, largely automatic way through a web of possibility [which is still in progress].
A point I have made over and over again, and to which David is unable to give what I would regard as a logical reply.
Reblak: So - it’s twaddle. All it means is that, for emotional convenience, by simply assuming God’s existence, we can attribute solutions we cannot otherwise find - to a mythical godhead that we invent and empower. Pure superstition – no evidence – just magic. Curiously, apply these assumptions of ‘arcane’ ability directly in favour of 'Mother Nature' and the problems disappear! Well – almost!
A lovely final twinkle. But from my view on the agnostic fence, it's not even “almost”! You are suggesting that the solutions we cannot otherwise find (especially to the problems of origin outlined above, but also to unexplained psychic phenomena) lie in blind, unconscious, chance-directed “Mother Nature”. Once more, if you believe that, you need just as much faith as you need to believe in “Mother Nature’s” other identity as a seeing, conscious, purpose-directed God.

If you agree that the processes can be out of his control although he can dabble (nudge) if he wants to, then it makes perfect sense to suggest that he actually wants them to be out of his control (i.e. allows the process to run freely) but can dabble (nudge) if he wants to. And that is the theistic scenario I have suggested and you have rejected.
DAVID: Balance of nature is logical for me.
dhw: Balance of nature means that life goes on so long as there are living organisms. It does not explain why your God, who according to you is capable of instantaneous creation of species (the Cambrian), and whose prime purpose was to create Homo sapiens, spent millions of years “mucking about” with all those hominins and hominids.
DAVID: Simple answer: God uses evolutionary processes, as history shows.
And so you jump from the irrelevance of “balance of nature” to evolution. You and I both believe history shows that all multicellular organisms, including humans, evolved. According to you, your God preprogrammed or dabbled “instant” species (the Cambrian) but for some unknown reason chose to “muck about” (reblak) with loads of hominins and hominids before producing the one species he really wanted: Homo sapiens. This apparently is explained by the fact that God’s logic is different from ours.
DAVID’S comment (on “energy and shrew brains”): Brains use lots of energy. This is an unusual adaptation to for the problem, but there is less food in winter. How the adaptation developed is unknown, but it involved reabsorption of skull plates which may have forced brain shrinkage. It is so massive a change it is akin to speciation. Research into this mechanism may unearth some information about speciation. And, if God arranges for new species, this may afford an insight into His methods.
Marvellous how organisms adapt. Looks to me like the work of those damned intelligent cell communities finding ways to cope with environmental conditions. If God exists, this would be a great example of his method of giving control to organisms to work out their own means of survival. But I suppose you will tell us that he controlled the shrewy shrinkage by dabbling or preprogramming it 3.8 billion years ago, so that life would continue until he could fulfil his primary purpose of producing the brain of Homo sapiens.

Why would He want to dabble if He doesn't want control. Your idea makes no sense.

Evolution requires balance of nature. You agree to that. The evolution of Cambrians showed development of new species over millions of years, no different than a few million years for human development. Evolution is evolution whenever and for how long it happened. 'Mucking' all along, don't you notice.

Shrewdly the shrews adapted either epigenetically, by a mechanism provided by God, or He stepped in. Either is possible, Only more research may tell us in the future.

Of course it makes sense. He sets the free-for-all process in motion, but if he doesn’t like what he sees, or gets tired of it, he intervenes. In other words, he only takes control if he wants to. On the other hand, looking at your scenario, if he is NOT in full control, how can he dabble and be sure to get what he wants?

Evolution can only take place if life goes on. Nobody could possibly disagree. “Balance of nature” means nothing more than that at different times different organisms are able to cope with different environmental conditions and therefore to survive.

Dabble and evolve.” Now apparently there is nothing special about the Cambrian after all – no almighty dabble, just evolution going the same old way. I’m happy with that. It fits in perfectly with my hypothesis that speciation of all kinds “mucks along” as different organisms devise different organs and strategies in the constant drive for survival and/or improvement. No overall plan, and especially no plan that links whales, nests and shrinking shrew skulls to the production of Homo sapiens’ brain.

Yes, the mechanism of cellular intelligence that organizes epigenetic adaptation, which as you say is “akin to speciation”, may have been provided by your God.

What you have left out is that everyone does NOT get to eat as a result, because 99% of species go extinct. The balance constantly changes in a manner that even you cannot link to the production of H. sapiens’ brain.

It’s difficult for me to remember something you left out. Of course the original forms evolved. I thought your argument was that the “abrupt start” was the result of your God dabbling to create instant species, as the original forms do not appear to have had any precedents. Hence Darwin’s big problem. So do you think the “original forms” were instant creations or not?
DAVID: As for humans, upright posture appeared, muscles reduced in size and then the brain grew. Each segment of evoluton had to start somewhere as God logically progresses with his plan.
That is precisely the sequence I am suggesting: upright posture resulted in new requirements, and the brain grew in order to fulfil the new needs. The exact opposite of your theory that your God expanded the brain in order to prepare for future tasks.

It’s good to see the gradual evolution of your concept from the H sapiens brain being the ONLY goal to its being the PRIMARY goal to its being A MAJOR goal. I agree that it is A MAJOR advance in evolution, and if God exists, I might even accept that after 3.X billion years he may have done a dabble. I have enormous difficulty in accepting that this major advance in evolution was THE or even the PRIMARY reason for the whole higgledy-piggledy bush of life on Earth. Can I think of another major goal? Yes indeed: the whole higgledy-piggledy bush of life on Earth, which provides an ever-changing spectacle and indeed a continuous source of wonderment. And before you make your complaint about “humanization”, remember that your hypothesis concerning the purpose of the brain was your God wanting a relationship with us and wanting us to think about him, which is just about as human as one can make him.

Limits and control are two different aspects of God. Of course He may have to use one method rather than another if limited in creation technique, but if He watches and steps in to dabble for course correction, He is in FULL control.

dhw: What you have left out is that everyone does NOT get to eat as a result, because 99% of species go extinct. The balance constantly changes in a manner that even you cannot link to the production of H. sapiens’ brain.
The link is enough energy to allow for enough time for evolutionary process to reach the complexity of the human brain. Without eating it doesn't survive to get there.

We must admit that since we share consciousness with Him, or as a part of Him, we have similarities in personality. He just isn't us.

The universe is expanding and the Hubble constant is narrowed to a small range now measured by three different methods, each of which has to make some estimates:
https://www.quantamagazine.org/colliding-neutron-stars-could-settle-cosmologys-biggest-...
"Scientists have hotly debated the cosmic expansion rate ever since 1929, when the American astronomer Edwin Hubble first established that the universe is expanding — and that it therefore had a beginning. How fast it expands reflects what’s in it (since matter, dark energy and radiation push and pull in different ways) and how old it is, making the value of the Hubble constant crucial for understanding the rest of cosmology.
"And yet the two most precise ways of measuring it result in different answers, with a curious 8 percent discrepancy that “is currently the biggest tension in cosmology,” said Dan Scolnic of the University of Chicago’s Kavli Institute for Cosmological Physics. The mismatch could be a clue that cosmologists aren’t taking into account important details that have affected the universe’s evolution. But to see if that’s the case, they need an independent check on the measurements.
"Neutron-star collisions — newly detectable by the Laser Interferometer Gravitational-Wave Observatory (LIGO) and Virgo detectors — seem to be just the thing.
***
:In an expanding universe, the farther away an astronomical object is, the faster it recedes. The Hubble constant says how much faster. Edwin Hubble himself estimated that galaxies move away from us 500 kilometers per second faster for each additional megaparsec of distance between us and them (a megaparsec is about 3.3 million light-years). This was a gross overestimate; by the 1970s, astrophysicists favored values for the Hubble constant around either 50 or 100 kilometers per second per megaparsec, depending on their methods. As errors were eliminated, these camps met near the middle. However, in the past year and a half, the Hubble trouble has reheated. This time, 67 stands off against 73.
***
"Each jump from one rung to the next risks miscalculation. And yet, in 2016, a team known as SH0ES used the cosmic distance ladder approach to peg the Hubble constant at 73.2 with an accuracy of 2.4 percent.
"However, in a paper published the same year, a team used the Planck telescope’s observations of the early universe to obtain a value of 67.8 for the current expansion rate — supposedly with 1 percent accuracy.
***
"The similarity of the two Hubble measurements “is amazing” considering the vastly different approaches used to determine them, said Wendy Freedman, an astrophysicist at the University of Chicago and a pioneer of the cosmic distance ladder approach. And yet their margins of error don’t overlap. “The universe looks like it’s expanding about eight percent faster than you would have expected based on how it looked in its youth and how we expect it to evolve,” Adam Riess of Johns Hopkins University, who led the SH0ES team, told Scientific American last year. “We have to take this pretty darn seriously.”
"The 67-versus-73 discrepancy could come down to an unknown error on one side or both. Or it might be real and significant — an indication that the Planck team’s extrapolation from the early universe to the present is missing a cosmic ingredient, one that changed the course of history and led to a faster expansion rate than otherwise expected.
***
"From the first neutron-star collision alone, Holz and hundreds of coauthors calculated the Hubble constant to be 70 kilometers per second per megaparsec, give or take 10. (The major source of uncertainty is the unknown angular orientation of the merging neutron stars relative to the LIGO detectors, which affects the measured amplitude of the signal.) Holz said, “I think it’s just pure luck that we’re smack in the middle,” between the cosmic-distance-ladder and cosmic-microwave-background Hubble estimates. “We could easily shift to one side or the other.”
"The measurement’s accuracy will steadily improve as more standard sirens are heard over the next few years, especially as LIGO continues to ramp up in sensitivity. "
Comment: Reblak take notice. We now have three ways to measure expansion, and they generally agree. The universe is expanding and therefore had a beginning. I condensed a very long article which explains the problems with each type of measurement.

Hello again. I fear that old age is a wearisome time. My mind still works well but transferring thoughts into typewritten script is a mentally exhausting one finger job – takes hours. This includes constant revision, back and forth until I am satisfied. This is reflected in my apparent failure to understand the Ag Web filing system. I can rarely locate the right location to post my reply – you have doubtless noticed.
I write fairly promptly my questions and answers, but then cannot find the relevant ‘reply’ box. So, I reply to some alternative entry. I have ended up simply not knowing whether I have actually sent what I wrote or not. This leaves me wide open to irritating, energy-wasting repetition and boring my audience.
I write all this only to explain that I never ever deliberately avoid any question.
I feel I have written and argued virtually all I need to about atheism and religion, so will conclude with two points that relate to evolution and cosmology.
First: I absolutely refute the idea that intelligence is required for 'Mother Nature' to do ‘her thing’. ‘She’ being intrinsically guided by automatic inbuilt responses that I designate as the 'Rules Of Engagement'. Nor is it correct to say that if how I describe the machinations of evolution is [more or less] correct, it should be relatively simple for man to unravel and trace back.
The clearest ‘analogical’ picture I can draw goes to show how [comparatively] easy it may be to initiate and complete a process and the hugely difficult problem faced by those who wish to unravel this by working back from completion to initiation.
So: Imagine a spread of undistinguished land at least ten miles square. On this land, our hero, a very average, ‘educationally disadvantaged’ Joe Bloggs, who is fed up with being belittled by the local Mr Smartiepants, decides to build a maze. On this empty tract he sets out a very convoluted pathway [tedious but easy]. He adds adjoining dead ends by the dozen. He then erects the usual impediments to visual range. After a very long time and many mistakes, he is satisfied and challenges Mr Smartiepants to enter the maze at the end and find his way to the beginning.
This proves exhausting - both mentally and physically. He not only cannot find his way but has to persuade Joe to rescue him! Eventually, Mr S invents all the things necessary to solve the problem – a helicopter and camera – all chewing up Mr S financially.
Here we see that being highly intelligent and the genius displayed in finally solving the problem has nothing whatsoever to do with the level of intelligence required to create it!
Second: The ‘Redshift’ problem.
Briefly, conventional cosmology holds that Redshift seen by astronomers represents light from star systems [galaxies] travelling out from the Universe at speeds in excess, in some cases, of an incredible 50,000 miles per second and may actually be increasing! [Eh! What?]
This ‘proves’ [assumption has now replaced fact!] that the Universe is expanding so it must have started out very much smaller. If you make it smaller you are compressing it. For a number of reasons, it was concluded that to make some sort of sense, the presently existing ‘model’ must have been compressed by a pre-existing universe into an incredibly tiny spot they chose to call a ‘Singularity’. At some point, the ‘Singularity’ suddenly expanded with huge force, forming a very large cloudy of gaseous matter. After about 13.5 billions years it had condensed into its present form. During the interregnum, it had been a more or less stationary ball of indeterminate size, busy generating galaxies. This suddenly expanded at what must have been a terrific speed. They know this by simply divining[!] the speed required to get that far away in the time allowed!
However, relying as they do, entirely upon the power of dear old gravity [the weakest known force] they could not make this fairyland physiology work. Undaunted, they tackled this by inventing Black Holes with incredible gravitational power.
Still a ‘no go’. Not enough Matter! Oh dear.
But – not to worry! The Matter must be there or the whole ideology would not exist – we just cannot see it. Thus are born Dark Matter and Dark Energy. However ...
Finally, it is realised that a lot is needed so they are promoted to about 96% of this Universe.
None of this can be explained by existing physical law and we cannot know what laws may have pertained in a previous universe but... they must have allowed this process.
Writing about this tripe is emotionally sickening. How anyone can swallow such invented balderdash really shocks me.
Whilst all ideas should be open to discussion, this one isn’t. ‘They’ maintain that it is [however difficult to believe], yet another wonder of scientific discovery and is the only possible solution!
This further encourages other airy-fairy ‘possible’ worlds and well-paid science magazine writers. And little else!
More needs to be said, so it will need another post

As regards your problems with the website, all you have to do is locate the relevant post(s) under the heading you are dealing with. If I want to reply to a post, I either print it out, or copy and paste it onto Word, and then edit it down to the points I wish to respond to.
Reblak: I feel I have written and argued virtually all I need to about atheism and religion, so will conclude with two points that relate to evolution and cosmology.
First: I absolutely refute the idea that intelligence is required for 'Mother Nature' to do ‘her thing’. ‘She’ being intrinsically guided by automatic inbuilt responses that I designate as the 'Rules Of Engagement'.
You are purporting to answer my post of 23 October, in which I expressed my agreement with much of what you wrote. However, you have ignored those sections with which I did not agree, which include the all-important problem of intelligence (see below). Joe Bloggs and the maze are no help, and the red shift argument to which you devote so much time is one I have repeatedly accepted on philosophical grounds (I can’t comment on the science). It is David not me who is defending the Establishment view. All I can do now is select and repeat the other problems I have with your arguments and hope that this time you will give me direct answers:
David: How do you know our universe is perfect? It is certainly very dangerous to life, except where it seems protected on Earth.
Reblak: This is easily dealt with. For something to be seen as imperfect requires a comparison. In a comparison, we may be able to select weak points. The Universe stands alone so cannot be ‘compared’. It has no faults as far as I can see.
“It has no faults as far as I can see” depends on your personal definition of perfection, imperfection and faults. You are quite right that there can be no comparison. That is why there is absolutely no point in imposing any of these concepts on it. I’ll repeat what I said in my earlier response: The universe is what it is and does what it does. That’s it.
Reblak: What part does this murder play in suggesting that God set the rules? […]
Since you clearly find this “maximum of cruelty” as repugnant as I do, I wonder how you square it with your personal concept of a “perfect” universe.
Reblak: Being virtually automatic, it has no consciousness, beyond a measure of ‘direction’ generated in sub-atomic and chemical awareness in differing states of being. Until the advent of life, there could be no conscious awareness.
Here you have touched on another subject I have raised in my responses: panpsychism, and the crucial question is precisely the degree of awareness or consciousness (I am not talking of human self-awareness) that may or may not be present in all materials. Do you believe it is sufficient to put together all the components necessary for the enormously complex mechanisms of life, reproduction, and the capacity for evolution leading from bacteria to the human brain? Such belief requires ignorance of these complexities (which seems unlikely in someone as learned as yourself) or a mighty degree of faith.
Dhw: Once more, then, the question of whether he exists or not boils down not to his possible nature but to whether you have sufficient faith in what you call “sub-atomical and chemical awareness” to believe that it is capable of producing the mechanisms described above – a question which you consistently ignore. NB This is a major factor in my own agnosticism, since I do not have that faith.
Reblak: This leaves 'Mother Nature' appearing to be doing it unaided, but – for some, that is not so. They believe God implemented all the 'know how' at outset. Nonetheless, David chooses to believe that his God is not actually all knowing, all powerful, nor absolutely perfect!
I know what others believe. I am challenging your own belief.
Reblak: So - it’s twaddle. All it means is that, for emotional convenience, by simply assuming God’s existence, we can attribute solutions we cannot otherwise find - to a mythical godhead that we invent and empower. Pure superstition – no evidence – just magic. Curiously, apply these assumptions of ‘arcane’ ability directly in favour of 'Mother Nature' and the problems disappear! Well – almost!
A lovely final twinkle. But from my view on the agnostic fence, it's not even “almost”! You are suggesting that the solutions we cannot otherwise find (especially to the problems of origin outlined above, but also to unexplained psychic phenomena) lie in blind, unconscious, chance-directed “Mother Nature”. Once more, if you believe that, you need just as much faith as you need to believe in “Mother Nature’s” other identity as a seeing, conscious, purpose-directed God.

dhw: You are purporting to answer my post of 23 October, in which I expressed my agreement with much of what you wrote. However, you have ignored those sections with which I did not agree, which include the all-important problem of intelligence (see below). Joe Bloggs and the maze are no help, and the red shift argument to which you devote so much time is one I have repeatedly accepted on philosophical grounds (I can’t comment on the science). It is David not me who is defending the Establishment view.
I'm simply presenting the latest science news, but the red shift is real as I've shown in my post: Friday, October 27, 2017, 22:57 It is estimate4d in three different methods with closely grouped results.

Hi again dhw
I have not ignored your queries.
You have plainly long been well aware of many of the ideas I support . I am glad that, at whatever level, we have an area of agreement. Nonetheless, it is this that makes it hard to understand why you choose to sit on the fence about aspects of religious belief. In the case of evolution you assume limits to the power of 'Mother Nature', in that ‘She’ may not be solely responsible for the emergence of ‘life and everything’, yet you consider, without a shred of evidence, attributing that power to a made up God you cannot actually believe in!
Not that it matters, we just hold different views,
Of fundamental importance [in understanding my beliefs] is to accept that the Universe encapsulates every form of every possible thing. No exceptions –none!
The way this functions is by being played out over time in ever changing conditions. This alone presents any researcher with presently insoluble problems. We may well have no verifiable awareness of those conditions at any particular point [including the present]. No problem for what I choose to call 'Mother Nature' which operates principally on automatic response mechanisms. Whilst there are various levels of intelligence extant at all times, they act in subordination to nature not its ‘direction’.
You may question my ideas because I maintain that all these things are eternal and therefore pre-existant. I do, but I also think that ‘local’ parts of the Universe are subject, over massive periods of time, to reconstruction. This perhaps reconstitutes an area, destroys the past and restarts the cycle. What is ‘ever present’ is the inate potential for whatever that can exist to reappear in suitable conditions.
Quite how this may occur is not as yet understood. My principal reason for thinking this is that geological formations show that some materials have been formed before others and all inorganic Matter preceded life. This suggests to me that the earliest life acts as a ‘marker’in a reconstituted area.
That the Universe is endless is also suggested by the probability that what is presently assumed to be the most distant edge has already had 13.5 +/- extra billions of years to move on from there!
I am pleased that we agree that a varying degree of awareness must exist in what I have described as the 'rules of engagement'. This is demonstrated especially in lifeforms. The flower ‘knows chemically’ that a visiting bee will act, albeit unconsciously, as a pollinator. Such an awareness was, almost certainly, first gained over umpteen thousands of years in an earlier life in the sea. It creates nectar which attracts pollinators. This a result of an extended period of chemical awareness in the plant – not a lucky chance.
Experience forms chemical memories tucked away in the genes [veritable giant libraries of intensely concentrated information]. Again, the elements of such information must work on the basis that each little bit engages automatically with the next in just one way, with inbuilt ‘instructions’ that dictate an unavoidable path. Conscious awareness is totally unnecessary.
The ideas I use to describe how nature uses this facility are offered, not as confirmed reality, but as a guidance that – leaving proven scientific fact on one side [no-one yet has this level of information] suggests strongly that this is [at least roughly] how my dear old 'Mother Nature' performs her magic. It expresses a logical base with which ‘She’, with automatic inevitability, ‘does the business’.
If, as I maintain, there is not, nor can there be any superpower involved, surely – surely there can be no other possibility but that nature, employing only physical law, must be fully responsible. A different natural process may well exist.
You surprise and disappoint me by dismissing my ‘maze’ analogy illustrating that working backwards to solve a problem can be far more difficult than working forwards. Consequently, this proves the falsity of the idea that when high [genius?!] levels need to be applied in solving a problem [e.g. my maze] they do not necessarily prove that high intelligence was needed to create it.
Dhw: “I’ll repeat what I said in my earlier response: The universe is what it is and does what it does. That’s it.”
That tells me nothing. You do not accept that nature does everything, especially life. Why wouldn’t it? How the Dickens can you know?
Dhw: ... [the]crucial question is precisely the degree of awareness or consciousness (I am not talking of human self-awareness) that may or may not be present in all materials. Do you believe it is sufficient to put together all the components necessary for the enormously complex mechanisms of life, reproduction, and the capacity for evolution leading from bacteria to the human brain? Such belief requires ignorance of these complexities... (or a mighty degree of faith).
This comment has been answered in the affirmative by my 'rules of engagement' theory.
To be continued.

Continuing:
My views are rational suppositions that employ physical reality. Faith is belief in defiance of reality. We will never agree on this. Frankly, it matters little – to paraphrase you – what is, is!
For Nature to do its work, the required components must be individually selected in the correct order and - critically - in suitable circumstances. We do not yet know what those circumstances are. Each step is going to result in a different outcome, one of many thousands.
A correct path to the human brain has consumed the lives of millions of intermediate creatures over millions of years, finally to follow the hominid path that has led to several types of near humans that culminated in Neanderthals, Cro-Magnon and Homo Sapiens Sapiens. Only we survived.
When a potentially more complex route is followed the viable outcomes are million fold, offering countless variations even within a species. In building brain parts, the existence of a complexity promotes its acceptance only of further ‘sympathetic’ additions until no further advantage is available.
The 'rules of engagement' to build an infant human are detailed in every reproductive system, sperm and egg. Those same or similar rules came about on Earth under conditions we do not know. If, as I affirm, these ‘building blocks are supplemented automatically, nothing in the way of a directing intelligence is required. No planning is involved, nor even remotely needed. No design factor can exist in these circumstances.
If you made a blank puzzle, its pieces would join together in one way only. A multiplicity of outcomes would arise if a few multi-fit pieces and differently shaped pieces are included. The Universe in and of its nature has plenty of these, so when the puzzle begins to form suitable new pieces are there and will eventually be harnessed to the organism. This process creates bumper harvests of successes, dead ends and failures. And can take millions of years entirely because it is not ‘designed’. In this sense, the choice of route includes an element of chance [or more likely, simply conditions] as to its further advance.
For a superpower to perform like this would make it a super idiot. Further comment would be pointless.
Dhw: Once more, then, the question of whether he exists or not boils down not to his possible nature but to whether you have sufficient faith in what you call “sub-atomical and chemical awareness” to believe that it is capable of producing the mechanisms described above – a question which you consistently ignore. NB This is a major factor in my own agnosticism, since I do not have that faith.
Here we go again. How can you say I have ignored your question yet quote part of my answer? I wrote at length of how I maintain that the conditions in which both inorganic and organic systems come about are intrinsic in a methodology that allows progressive automatic and systematic evolution, no matter how complex the process may become.
If I didn’t believe it, I would not propound it.
You are suggesting that the solutions we cannot otherwise find (especially to the problems of origin outlined above, but also to unexplained psychic phenomena) lie in blind, unconscious, chance-directed “Mother Nature”. Once more, if you believe that, you need just as much faith as you need to believe in “Mother Nature’s” other identity as a seeing, conscious, purpose-directed God.
Nature is not chance directed and there is no reason to think she is. Whilst consciousness does not pertain there is always an element of atomic and chemical awareness at work. Perhaps I should reaffirm my position yet again in the context of my stated views on how the natural world functions.
Everything – everything, exists by virtue of capability extant in the Universe and nowhere else! There isn’t an ‘anywhere else’ anyway!
Each and every nuance of feeling, imagination, emotional stress or psychic phenomena are directly created by the activities of the brain, perhaps in reaction to some stimulus, internal or external, which may [obviously] be affected by outside influences. Whilst we can discuss or write detailed reviews of them, they cannot be seen or felt outside a brain.
There is also an ‘aura’ that surrounds every living being. This is caused by radiation of the bodies energy and has been shown on camera. I do not know its limitations but it may be possible that we know of it when ‘auras’ are in contact. People don’t like it when ‘their space’ is invaded, a feeling that suggests that their own aura has ‘sensed’ another and the brain interprets this contact as ‘undesirable’.
It may be possible that an ‘extended’ aura may contact, for example, a hidden enemy. This could [if true] account for the awareness sometimes claimed for the prowess of some hunted/hunting creature. The ‘awareness’ would be an electrical exchange only capable of reception by the brain. There is no possibility that mental power can exert any force to move any object – telekinesis.

To my way of interpreting what you propose: an inorganic universe exists and somehow is purposely directed to produce organic living mater which ends up in big brained humans, all not by chance but through some sort of intrinsic mechanisms, filled with information. You don't explain where the purposeful direction comes from, nor do you identify the origin of the information that some how arose from an inorganic universe. Information is immaterial. You are accepting all of this on faith as a proposed explanation of our reality. Is that a fair summary? I find your beliefs the equivalent of my God.

Hi reblak. Before I respond to your post, may I please ask you to be more direct and concise in your own responses. If I reproduce and respond to every point you raise, we shall have Parts One, Two, Three and Four! Apologies if this sounds schoolmasterly, but it makes for more manageable discussion if we narrow the focus and stay within the given framework (approx. 900 words maximum).
reblak: In the case of evolution you assume limits to the power of 'Mother Nature', in that ‘She’ may not be solely responsible for the emergence of ‘life and everything’, yet you consider, without a shred of evidence, attributing that power to a made up God you cannot actually believe in!
I don’t “assume” anything. You have said ‘She’ is unconscious, though there is a “sub-atomic and chemical awareness in differing states of being”. I asked you if you thought this awareness was “sufficient to put together all the components for the enormously complex mechanisms of life, reproduction and the capacity for evolution leading from bacteria to the human brain.” You have described organismal "awareness", apparently sourceless in-built instructions and rules of engagement that make those complexities automatically, and then conclude that if there is no superpower involved, your unconscious Nature “must be fully responsible”. Of course, if you are right, you are right. Again in Part Two: “If, as I affirm, these building blocks are supplemented automatically, nothing in the way of a directing intelligence is required.” That is the IF I am questioning! I’ll come back to this later, but there is no scientific evidence for your belief that there is a sub-atomical and chemical awareness which can in time automatically produce organs and organisms so complex that our finest minds are still trying to unravel their workings. This is pure faith. I am not propagating any belief of my own – I remain open-minded because I can’t accept ANY of the basic premises (David’s conscious God, the creative genius of chance, or that of your unconscious ‘Mother Nature’). Not accepting does not, however, mean rejecting.
Dhw: “The universe is what it is and does what it does. That’s it.”
Reblak: “This tells me nothing. You do not accept that nature does everything, especially life. Why wouldn’t it? How the Dickens can you know?”
Firstly, you have taken my remark completely out of context. You say the universe is perfect, and then tell us: “It has no faults as far as I can see.” What is your point in calling it “perfect”? Your comment is clearly subjective and based on no conceivable criterion. THAT is why I said the universe is what it is. Secondly, as above, I do not know if blind, unconscious nature can or can't produce all the complexities of life. You are the one with the fixed belief.
Reblak: Nature is not chance directed and there is no reason to think she is. Whilst consciousness does not pertain there is always an element of atomic and chemical awareness at work.
I have several times mentioned my panpsychist hypothesis, but you have never responded. This may be a point in common between us, but I find your own hypothesis somewhat confusing – for instance, organisms (and chemicals) are aware but not conscious. I see the terms as synonymous, but awareness/consciousness exists in different degrees. Basically, the proposal is that all matter has some form of mental component, or consciousness/awareness. In inorganic materials this is rudimentary, but it entails consciousness of the presence of other materials, and of interactive effects. This consciousness is enhanced as materials combine and experience new effects, and in due course it reaches the point at which combined materials produce the intelligence (ability to use the information of which they are conscious) to create rudimentary forms of life which can reproduce and crucially – in time – combine into other forms of life. From then on, evolution is directed by the interaction between random environmental changes and organisms that either adapt, perish, or invent new combinations to exploit new opportunities. In contrast to top-down theistic evolution, it is a natural bottom-up progression. But the hypothesis depends entirely on the belief that inorganic matter has a degree of consciousness which can expand so much as to eventually produce our own human degrees of self-consciousness. Does this correspond to your own hypothesis or not? If not, what are the differences? (NB for me it is a hypothesis, not a belief.)
The subject of whether “each and every nuance of feeling” etc. is created by the brain is that of dualism v materialism, which we have discussed at great length on this forum, and which David and I are still discussing on two current threads; the subject of the “aura” links up with the much discussed work of Sheldrake and others, but again I don’t know why you mention it here. Telekinesis and other psychic powers are another fascinating subject we have discussed and will continue to discuss, but we can’t cover everything at the same time! Hence my plea to keep these posts concise and geared to particular points. (There are three here: faith in the ability of rudimentary awareness and automatic “rules of engagement” to produce the complexities of life; the pointlessness of calling the universe “perfect”; the hypothesis of rudimentary consciousness in materials evolving into organic intelligence.)

Sorry I overstepped the mark in my last episodic post.
Surely, in the absence of proof, any claims made, whether religious or not, can be degraded as ‘sourceless’! In point of fact my claims are sourced in the only knowable entity. My conclusions [possibly illusions – I am most certainly not infallible!] have the quality of obedience to known physical laws and not the wholly invented capacities of an unproven, completely imaginary God or superbeing. That alone makes my ideas credible by comparison.
Dhw: I asked you if you thought this awareness was “sufficient to put together all the components for the enormously complex mechanisms of life, reproduction and the capacity for evolution leading from bacteria to the human brain.”

Secondly, as above, I do not know if blind, unconscious nature can or can't produce all the complexities of life. You are the one with the fixed belief.
Whilst my beliefs are firmly held they are far from ‘fixed’. They have altered dramatically in several areas of study. There is a high degree of understanding as to how atomic particles combine by entirely natural processes. These processes themselves are altered when conjunctions are made. It cannot be that they remain fully independent when acting in joined group. H2O becomes water, a qualitative change that reflects new 'rules of engagement' that not only rule that configuration but set conditions governing whether and what type of future acquisitions can be made. This latter condition will probably at some point, become capable of engaging with other [system compliant] tiny organisms that may introduce the prospect of advance in the same or yet another direction.
Were this not so, the diversity we see could not exist. There is a reasonable understanding of how atomic particles combine by natural processes. These combinations are altered when conjunctions are made. It cannot be that they remain fully unaltered and independent when acting in joined groups.
H2O becomes water, a qualitative change that reflects new 'rules of engagement'. They not only rule that configuration but also set conditions governing whether and what type of future acquisitions can be made. This latter condition will, at some point, have become capable of engaging with other [system compliant] tiny organisms that may introduce prospect of advance in the same or yet another outcome.
As only Nature is known to exist it acts alone. Introducing outside forces that ‘might’ exist is palpable nonsense.
My [contradictory?] remarks about nature being perfect were simply a recognition that my views are not known to be correct. I of course, feel completely certain they are right on the money! The ‘point’ of my comment is to counter the baseless idea that it is not perfect. Whilst I am not at all keen on arguing whether an idea is a faith or belief, I do care that it should be reasonably possible and conform with natural law. If it does it is discussable, if not...
I don’t care what you choose to call it. In substance I agree your synopsis. I cannot see why you have such difficulty in ‘allowing’ the interaction of inorganic materials to qualify as the precursor of ‘awareness’. Something must - it hasn’t sprung, fully formed out of thin air!
I maintain [as you may have noticed!] that everything flows in automatic succession, from the immutable laws of the Universe. Therefore logic dictates that whatever pre-exists mankind, such as awareness, is an ‘advantage’ heralded by awareness.
The border between organic and inorganic material is crossed when a purely atomic ‘sense’ becomes {probably first in plant life] a chemical awareness. Were I able to cogently prove this I would be the most scientifically advanced human on Mother Earth!
In animal [fishy] evolutions in the sea, this perhaps still initially chemical awareness was insufficient, but informed the genetic structure that greater sensitivity [consciousness] was a paramount need. Quite how these properties formed is unknown, but form they have!
I mention it because you queried “each and every nuance of feeling” as being experienced exclusively in the brain. All feeling lives in the brain. I mentioned aura etc to obviate its being introduced as an out of body experience.

reblak: Surely, in the absence of proof, any claims made, whether religious or not, can be degraded as ‘sourceless’!
I presume you are referring to my comment on your “in-built instructions” and “rules of engagement”. Yes, if you cannot identify a source, then it is sourceless, and your response below that the source of these instructions and rules is “known physical laws” is pure tautology!
reblak: In point of fact my claims are sourced in the only knowable entity. My conclusions [possibly illusions – I am most certainly not infallible!] have the quality of obedience to known physical laws and not the wholly invented capacities of an unproven, completely imaginary God or superbeing. That alone makes my ideas credible by comparison.
My focus throughout has been on the complexities of life. What known physical law automatically leads to life? It is no defence of your claim to say that God is unproven when your own hypothesis is also unproven. I am not asking you to believe in God. I am challenging the assumptions underlying your own faith. You then quote my post. The first point is as above. You tell us “how atomic particles combine by entirely natural processes” and continue: “H2O becomes water, a qualitative change that reflects new 'rules of engagement' that not only rule that configuration but set conditions governing whether and what type of future acquisitions can be made. This latter condition will probably at some point, become capable of engaging with other [system compliant] tiny organisms that may introduce the prospect of advance in the same or yet another direction.” This is an astonishing leap from inanimate water to living organisms! So let me ask again: what known physical law automatically leads from inorganic matter to living cells endowed with the ability to reproduce themselves and to respond consciously and actively to their environment?
The second point concerned your calling the universe “perfect”. Your reply is:
"My [contradictory?] remarks about nature being perfect were simply a recognition that my views are not known to be correct. I of course, feel completely certain they are right on the money! The ‘point’ of my comment is to counter the baseless idea that it is not perfect."
There are no criteria for the perfection or imperfection of the universe.'Perfect' is just as baseless as ‘imperfect’. Where is this meant to lead? It certainly has nothing whatsoever to do with your claims that blind, unconscious Mother Nature created everything automatically according to known laws. I’ll be happy to drop this "perfection" subject, though, as I simply don't see the point.
The third subject was my panpsychist hypothesis, and I asked you if it fitted in with your own – though I found yours confusing, especially with its unexplained distinction between awareness and consciousness.
reblak:In substance I agree your synopsis. I cannot see why you have such difficulty in ‘allowing’ the interaction of inorganic materials to qualify as the precursor of ‘awareness’. Something must - it hasn’t sprung, fully formed out of thin air!
My hypothesis does not treat the interaction as a precursor - it suggests that inorganic materials already have a rudimentary awareness which becomes enhanced through their interaction until they reach a point where they produce the first rudimentary forms of life. As I tried to make clear, however, even this rudimentary awareness is pure speculation, and the idea that it might become “intelligent” enough to create living, self-reproducing organisms is equally speculative. I would reverse your comment: I cannot see why you have such difficulty in recognizing that belief in such speculations has no basis in science and requires a leap of faith akin to that of belief in a God or belief in the blind, unconscious creative genius of ‘Mother Nature’. However, you continue as follows (edited):
reblak: The border between organic and inorganic material is crossed when a purely atomic ‘sense’ becomes [probably first in plant life] a chemical awareness. Were I able to cogently prove this I would be the most scientifically advanced human on Mother Earth!
I don’t want to haggle over the terms you use, because broadly speaking this fits in with my panpsychist hypothesis. The point I am making is that it IS only a hypothesis. It’s no use talking of “known physical laws” and automatic processes when we know of none that can account for any sort of awareness, any sort of life, any sort of reproduction.
Reblak: Quite how these properties formed is unknown, but form they have!
Precisely. Nobody is denying that life, reproduction and consciousness formed. How they formed is the whole point of this discussion. I have suggested that your hypothesis is based on faith in certain sourceless, unproven, perhaps even unprovable assumptions. I have the same objection to faith in a God, and to faith in chance. I appreciate your earlier acknowledgement of your fallibility, but if you say you could be wrong, and if you cannot provide any evidence - apart from your personal assumptions - that your explanations are correct, perhaps the dismissal of other people’s beliefs as “palpable nonsense” might be seen as a case of pots and kettles. Personally, I would avoid such terms, but I speak of course as an agnostic!
Cosmology: forming universe structures
by David Turell , Monday, April 27, 2020, 23:02 (1670 days ago) @ John Kalber
A new complex computer study on galaxy formation and placement:
https://phys.org/news/2020-04-elegant-solution-reveals-universe.html
"A 10-year survey of tens of thousands of galaxies made using the Magellan Baade Telescope at Carnegie's Las Campanas Observatory in Chile provided a new approach to answering this fundamental mystery.
***
"The first galaxies were formed a few hundred million years after the Big Bang, which started the universe as a hot, murky soup of extremely energetic particles. As this material expanded outward from the initial explosion, it cooled, and the particles coalesced into neutral hydrogen gas. Some patches were denser than others and, eventually, their gravity overcame the universe's outward trajectory and the material collapsed inward, forming the first clumps of structure in the cosmos.
"The density differences that allowed for structures both large and small to form in some places and not in others have been a longstanding topic of fascination. But until now, astronomers' abilities to model how structure grew in the universe over the last 13 billion years faced mathematical limitations.
***
"'A key goal of our survey was to count up the mass present in stars found in an enormous selection of distant galaxies and then use this information to formulate a new approach to understanding how structure formed in the universe," Kelson explained.
***
"Doing this revealed that denser clumps grew faster, and less-dense clumps grew more slowly.
They were then able to work backward and determine the original distributions and growth rates of the fluctuations in density, which would eventually become the large-scale structures that determined the distributions of galaxies we see today.
"In essence, their work provided a simple, yet accurate, description of why and how density fluctuations grow the way they do in the real universe, as well as in the computational-based work that underpins our understanding of the universe's infancy."
Comment: There is no change in theory but a much better understanding of the universe's evolution.

Redshift: This is of fundamental importance in seeking evidence that may prove vital to the fate of scientific cosmological theory. If it relates only to speed of recession, I and everything I have to say is wrong. Even so, the puted effect may have another, physically rational explanation. HoweverI don’t think so. Let’s get at it.
The work of the American astronomer Edwin Hubble [1889–1953)] has been at the centre point of the Redshift controversy. In 1925 he demonstrated the existence of other galaxies besides the Milky Way, profoundly changing the way we look at the universe. Later, in 1929, he definitively demonstrated that the universe was expanding, (considered by many as one of the most important cosmological discoveries ever made), and formulated what is now known as Hubble's Law [this states that the greater the distance between any two galaxies, the greater their relative speed of separation] to show that the other galaxies are moving away from the Milky Way at a speed directly proportionate to their distance from it. He has been called one of the most influential astronomers since the times of Galileo, Kepler and Newton.
Hubble: “But these lectures will present a remarkable situation. The familiar interpretation of red-shifts seems to imply a strange and dubious universe, very young and very small. On the other hand, the plausible and, in a sense, familiar conception of a universe extending indefinitely in space and time, a universe vastly greater than the observable region, seems to imply that red-shifts are not primarily velocity-shifts.
In view of this possible conflict, whether of facts or theories or speculations, the observer is inclined to keep an open mind and to adopt parallel working hypotheses for the interpretation of his explorations. He may assume, first, that red-shifts are velocity-shifts, or, secondly, that red-shifts result from some unknown principle that does not involve actual motion, and always, of course, he will search for some empirical, critical test for distinguishing between the two assumptions, between motion and no motion.”
Neither here or later does Hubble state that the Redshift phenomenon is proven -either way.
So, this suiting their procreation stance, establishment science announced at once that their interpretation of Redshift [that ‘proved’ the Universe is expanding] had been established as correct by the great Hubble! Behind the scenes, Hubble objected but was pressured into silence. Many were not deceived but soon learned that if they did not shut up their jobs could disappear or promotions be blocked. No university would defy the hierarchy.
Most shut up.
In 1950, Immanuel Velikovsky published the volume, 'Worlds in Collision' and sent a shockwave ricocheting through a whole range of research and scientific belief. This nasty “You are to be ostracised if you so much as mention it!” attitude can be compared to Herr Doctor Joseph Goebbels - but he wasn’t as effective! He had to kill people, the scientific hierarchy just gets you sacked, life and reputation destroyed – you move from a laboratory or a giant telescope onto the street – dustcart and broom optional extras!
Returning to Redshift:
Postwar it has been NASA that keeps this iron like control over what scientists are allowed think, let alone say!
A renowned professional astronomer, Halton Arp [29 years at the Palomar telescope] authored an amazing, highly accurate catalogue of unusual galaxies titled Atlas of Peculiar Galaxies, which was first published in 1966. Arp realized that astronomers understood little about how galaxies change over time, which led him to work on this project. This atlas was intended to provide images that would give astronomers data from which they could study the evolution of galaxies. Arp later used the atlas as evidence in his debate on quasi-stellar objects (QSOs).
Based on its citation by other astronomers, Arp's atlas is recognized now as an excellent compilation of interacting and merging galaxies. Many objects in the atlas are referred to primarily by their Arp number. Many of these objects (particularly Arp 220) are also used as spectral templates for studying high-redshift galaxies.

reblak: Redshift: This is of fundamental importance in seeking evidence that may prove vital to the fate of scientific cosmological theory. If it relates only to speed of recession, I and everything I have to say is wrong. Even so, the puted effect may have another, physically rational explanation. HoweverI don’t think so. Let’s get at it.
The work of the American astronomer Edwin Hubble [1889–1953)] has been at the centre point of the Redshift controversy. In 1925 he demonstrated the existence of other galaxies besides the Milky Way, profoundly changing the way we look at the universe. Later, in 1929, he definitively demonstrated that the universe was expanding, (considered by many as one of the most important cosmological discoveries ever made), and formulated what is now known as Hubble's Law [this states that the greater the distance between any two galaxies, the greater their relative speed of separation] to show that the other galaxies are moving away from the Milky Way at a speed directly proportionate to their distance from it. He has been called one of the most influential astronomers since the times of Galileo, Kepler and Newton.
Hubble: “But these lectures will present a remarkable situation. The familiar interpretation of red-shifts seems to imply a strange and dubious universe, very young and very small. On the other hand, the plausible and, in a sense, familiar conception of a universe extending indefinitely in space and time, a universe vastly greater than the observable region, seems to imply that red-shifts are not primarily velocity-shifts.
In view of this possible conflict, whether of facts or theories or speculations, the observer is inclined to keep an open mind and to adopt parallel working hypotheses for the interpretation of his explorations. He may assume, first, that red-shifts are velocity-shifts, or, secondly, that red-shifts result from some unknown principle that does not involve actual motion, and always, of course, he will search for some empirical, critical test for distinguishing between the two assumptions, between motion and no motion.”Neither here or later does Hubble state that the Redshift phenomenon is proven -either way.
So, this suiting their procreation stance, establishment science announced at once that their interpretation of Redshift [that ‘proved’ the Universe is expanding] had been established as correct by the great Hubble! Behind the scenes, Hubble objected but was pressured into silence. Many were not deceived but soon learned that if they did not shut up their jobs could disappear or promotions be blocked. No university would defy the hierarchy.
Most shut up.
In 1950, Immanuel Velikovsky published the volume, 'Worlds in Collision' and sent a shockwave ricocheting through a whole range of research and scientific belief. This nasty “You are to be ostracised if you so much as mention it!” attitude can be compared to Herr Doctor Joseph Goebbels - but he wasn’t as effective! He had to kill people, the scientific hierarchy just gets you sacked, life and reputation destroyed – you move from a laboratory or a giant telescope onto the street – dustcart and broom optional extras!
Returning to Redshift:
Postwar it has been NASA that keeps this iron like control over what scientists are allowed think, let alone say!
A renowned professional astronomer, Halton Arp [29 years at the Palomar telescope] authored an amazing, highly accurate catalogue of unusual galaxies titled Atlas of Peculiar Galaxies, which was first published in 1966. Arp realized that astronomers understood little about how galaxies change over time, which led him to work on this project. This atlas was intended to provide images that would give astronomers data from which they could study the evolution of galaxies. Arp later used the atlas as evidence in his debate on quasi-stellar objects (QSOs).
Based on its citation by other astronomers, Arp's atlas is recognized now as an excellent compilation of interacting and merging galaxies. Many objects in the atlas are referred to primarily by their Arp number. Many of these objects (particularly Arp 220) are also used as spectral templates for studying high-redshift galaxies. Arp 220 is the result of a collision between two galaxies which are now in the process of merging. [Wikipedia].
NASA has used this map continuously, confident that it is accurate. Despite this, when in
1972 Arp showed that Redshift was clearly active between these galaxies and therefore could not represent only speed of recession. He was immediately black-balled by NASA, who forced him to be sacked, denied telescope access in the USA and driven to find work in Germany.NASA claimed Arp had incompetently confused ‘inline’ galaxies with colliding galaxies! Arp was outraged by this blatant lie, but the NASA ‘nazis’ are, even today, ruthlessly dominant – twaddle like Big Bang and its spinoffs must not be questioned! This fantasy will soon now fall like the Berlin Wall!

I'm sorry you think I have ignored anything, let alone a brand new posting I knew nothing of.
My answer to Hubble's Law together with Einstein's 'Constant' is that they are neither laws nor constant.
They are figments of imagination born of a false interpretation of how the Universe works. Both men were intense observers of the mysteries of our perfect Universe and sought explanations that might throw light into a veritable 'darkness'. They have made us think.
Both men subsequently cast doubt upon their 'findings'.
Their theories reflect [particularly Einstein] a tremendous effort to rationalize a universe that they thought to be finite and expanding. Einstein's Constant is bedevilled as being in 'constant' need of revision! Hubble's Law insists that the further away galaxies are, the faster they recede!
Quite irrational. Irrational because no feasible explanation for this [cubist?] behaviour exists. Until it can be actually proved [not opined!] that my lovely Universe is not eternal but came out of nothing, I will sustain my ‘belief’.
What power has held together so many galaxies that are billions of years old and thousands of light years across? Why are they of so many different shapes and differing densities?
These questions suggest that ‘local’ conditions vary widely. Were this not so and galaxies are doing a ‘Louis Hamilton’, they like racing cars would look virtually identical!
I do not believe that galaxies can rush off at speeds in excess of 50,000 miles per second. Nor do I accept that gravity [the weakest force] can hold even a stationary galaxy together.
I ask that if, as propounded, we are all rushing away how the heck can galaxies collide? To collide they must first form elsewhere, then travel [outwards?] towards each other on a narrowing path. But, curiously, only a few do this. It introduces a new parameter – direction of travel!
If I am right I can hardly be expected to believe in what are nothing more than ‘ideas’ -minus substance – i.e. superstitions grounded in financially rewarding science fiction! Sad to say religious belief still dominates the higher reaches of most disciplines and distorts the view. This attitude sanctifies and accepts the impossible because there might be a God at work. Unbelievable! [But true].
Einstein, a truly brilliant original thinker, struggled to understand the basic’s of the Universe. Telescopy was in its infancy as a tool of cosmology. He correctly concluded that the interpretation of time and space dominate any ideas we may have. All of which seemed wrong anyway. He decided to introduce a totally new conception – Space-Time – as a physical reality. With a physical reality, you can do physical things and generate physical outcomes. He found Space-Time susceptible to grooving by planets and it is this, not gravity, that we experience. This offended against Newtonian physics and was not welcomed [it is also a rubbish theory!]
Other aspects were greeted as marvellous and ‘proven’ in research, becoming the establishment’s scientific truth.
But for the sceptic, it is an impossible scenario. In 1905 space was a word used to mean an area surrounding us that is basically empty. We now know that is wrong – but Einstein didn’t. You cannot bend space. Gravitational effects bend the paths of ‘physicalities’ through space. Space is insubstantial so cannot ‘bend’.
Time is an invented ‘ruler’ that we use to measure the distance between events. No events, no time. So, ‘Space-Time’ is nothing and non-existant. Consequently, ideas so founded are going to be wrong – guaranteed!
I have yet to see a proposition actually proved using Einstein’s theories. Lauded ‘proofs’ are all open to different interpretations. Tragically, latter-day science is riddled with phony ‘evidence’and what can only be seen as deliberate suppression and distortion intende to support a rigid ‘establishment’ position.
I have noticed that over the past year or two, articles in scientific magazines now occasionally discuss physics that challenge [albeit mildly] concepts such as gravity, Black Holes and Dark Matter. Time has carried off the original power boys and ‘old’ ideas are harder to suppress. A pity I will not see it so late in my lifetime.
Those who would like more scientific evidence should spend time trawling the internet seeing what people such as Wal Thornhill [of the Electric Universe] have to say. There are many video presentations on Utube. No outrageous claims, just logical, alternative interpretations.

If you would watch the daily entries you could follow the discussion and the new articles I present. Yesterday's answer to you gave you the reference. It discussed three methods of measuring the expansion all of which were in fairly close agreement.

The Cosmologic constant is revised because of new measurements. That it is expanding faster was shown by the supernova studies.

Without Einstein we could not send rockets to anywhere. We slingshot them around planets! Arthur Edington's 1919 proof has been validated many times since.

From gravitational waves and light:
https://www.livescience.com/64191-einstein-graviton-live-science.html?utm_source=ls-new...
"In 2017, astronomers for the first time detected both gravitational waves and light from a single event: a neutron star collision. Now, researchers are using data from that event to confirm some basic facts about the universe.
"In a paper first uploaded Nov. 1 to the preprint server arXiv (which Live Science first saw reported on ScienceAlert), researchers announced that they found no evidence of "gravitational leakage." Scientists had thought it was possible for gravity to penetrate high dimensions (those beyond the four that humans experience — up/down, side to side, forward/backward, time) even though light does not. If that happened, the force of gravity would lose more of its energy than light does while passing through space. But comparing the light and gravitational waves from that neutron star collision showed that this wasn't happening.
"All our dimension's gravity appears to be staying right where it belongs, as Albert Einstein predicted in his theory of general relativity.
" In this illustration, a hot, dense, expanding cloud of debris gets stripped from neutron stars just before they collide.
"Gravity is big and weird and difficult to study. It moves through space as a wave, sort of like how light does. But these waves are subtle and difficult to detect. They occur in measurable amounts only after massive events, like the collision of black holes. Humanity didn't spot its first gravitational wave until 2015. Then, in 2017, astronomers for the first time detected both gravitational waves and light from a single event: a neutron star collision. Now, researchers are using data from that event to confirm some basic facts about the universe.

"The researchers in the new study also analyzed gravitational waves to see whether the graviton — the theoretical particle that carries gravity — might have mass, like other particles do. If there was such a thing as a "massive graviton," gravitational waves would also have mass, and if these waves had mass, they would exhibit signs of momentum, unlike light particles, which are massless. That would also be a violation of general relativity. But, again, it didn't happen.
"Overall, researchers found, Einstein's theories of gravity remain basically intact. Someday, that might change. But it hasn't yet, even after two neutron stars slammed into each other."

A wobbly presessing proves it again:
https://www.sciencenews.org/article/wobbling-orbit-pulsar-proves-einstein-right-again-r...
"Over those two decades, the orbit of the pulsar has been slowly precessing, astronomers report. The precession isn’t much — the orbit’s tilt drifts by just 0.0004 degrees per year. But it matches what researchers expect if the neighboring white dwarf whips up spacetime as it spins.
***
"This finding isn’t the first time that researchers have observed frame dragging. Satellites in Earth’s orbit have captured the relatively puny effect around our planet (SN: 11/24/15). And astronomers also have observed fluctuations in the frequency of X-ray light coming from a black hole, where frame dragging should be quite intense, suggesting that gas may be precessing around it.
"The new observation “is much more direct than mine,” says Adam Ingram, an astrophysicist at the University of Oxford who studied the black hole. “I can only infer that something is precessing in black hole systems, whereas the precision radio observations presented here leave little room for ambiguity.'”
Comment: Right again.

Another report with a good explanation:
https://cosmosmagazine.com/physics/catching-frame-dragging-in-action?utm_source=Cosmos+...
"Scientists studying tiny changes in a pulsar’s signal have proven that massive rotating objects drag surrounding spacetime around with them as they spin.
"The process, called frame dragging, was predicted more than a century ago by Austrian mathematicians Josef Lense and Hans Thirring, as a consequence of Einstein’s Theory of General Relativity.
***
"Prior efforts to measure it had been conducted via satellite experiments in the gravitational field of the rotating Earth. But the Earth simply isn’t massive or rapidly rotating enough to make the best laboratory.
"Instead, Bhat and colleagues from Australia, Germany, Denmark and New Zealand turned to an unusual astronomical pulsar known as PSR J1141-6545, which researchers have been studying for 20 years via Australia’s 64-metre Parkes radio telescope.
"Pulsars are tiny, hyper-dense stellar remnants that emit very, very regular radio signals.
“Pulsars are cosmic clocks,” says Vivek Venkatraman Krishnan, from the Max Planck Institute for Radio Astronomy, Germany, the corresponding author of a paper in the journal Science.
"PSR J1141-6545 is no ordinary pulsar, however. It’s a pulsar in orbit around an extremely rapidly rotating white dwarf star – itself only the size of the Earth, but 300,000 times denser.
***
"To measure it, the team studied the arrival times of PSR J1141-6545’s pulsar signals for 20 years. What they found was a slow change – in the order of 1.5 parts in 3.5 million – indicating that the pulsar’s orbit was slowly changing orientation in response to the frame-dragging effect of the nearby white dwarf.
“'It essentially changes the orientation of the pulsar’s orbital track, but by an extremely tiny bit,” Bhat says, adding that this was why it took 20 years of “patient monitoring” to spot it.
"But the result, he says, was worth the effort.
“'[This] is yet another stunning verification of Einstein's theory of gravity, which is undeniable shining even a century after its formulation,” he says. “No other theories have been explored or proven to that depth and rigour.
“'[Einstein’s theory] is most definitely the theory of gravity we should continue to adopt. It is also the foundation theory we use to understand how the Universe works, how it has come about, and how it evolves.”
"And how best to describe this concept of frame dragging? "If you are after a useful analogue, visualise a spinning ball in a bowl of thick syrup – here the ball is like white dwarf and syrup is like the fabric of space-time," Bhat suggests. "
Comment: Of course Einstein is right, amazingly right on the button. Where does this leave the quantum gravity theories, like string theory? Einstein uses spacetime which means time is more than a series of events.

Using black hole measurements:
https://phys.org/news/2020-10-einstein-description-gravity-harder.html
"Einstein's theory of general relativity—the idea that gravity is matter warping spacetime—has withstood over 100 years of scrutiny and testing, including the newest test from the Event Horizon Telescope collaboration, published today in the latest issue of Physical Review Letters.
"According to the findings, Einstein's theory just got 500 times harder to beat.
***
"We expect a complete theory of gravity to be different from general relativity, but there are many ways one can modify it. We found that whatever the correct theory is, it can't be significantly different from general relativity when it comes to black holes. We really squeezed down the space of possible modifications," said UArizona astrophysics professor Dimitrios Psaltis
***
"To perform the test, the team used the first image ever taken of the supermassive black hole at the center of nearby galaxy M87 obtained with the EHT last year. The first results had shown that the size of the black-hole shadow was consistent with the size predicted by general relativity.
***
"'Using the gauge we developed, we showed that the measured size of the black hole shadow in M87 tightens the wiggle room for modifications to Einstein's theory of general relativity by almost a factor of 500, compared to previous tests in the solar system," said UArizona astrophysics professor Feryal Özel, a senior member of the EHT collaboration. "Many ways to modify general relativity fail at this new and tighter black hole shadow test.'"
Comment: It seems that quantum considerations will have to be added to any new theory while the general relativity will hold its position.

The latest study gets the same result:
https://phys.org/news/2021-01-astronomers-universe-billion-years.html
"From an observatory high above Chile's Atacama Desert, astronomers have taken a new look at the oldest light in the universe.
"Their observations, plus a bit of cosmic geometry, suggest that the universe is 13.77 billion years old—give or take 40 million years. A Cornell University researcher co-authored one of two papers about the findings, which add a fresh twist to an ongoing debate in the astrophysics community.
"The new estimate, using data gathered at the National Science Foundation's Atacama Cosmology Telescope (ACT), matches the one provided by the standard model of the universe, as well as measurements of the same light made by the European Space Agency's Planck satellite, which measured remnants of the Big Bang from 2009 to '13.
***
"'Now we've come up with an answer where Planck and ACT agree," said Simone Aiola, a researcher at the Flatiron Institute's Center for Computational Astrophysics and first author of one of two papers. "It speaks to the fact that these difficult measurements are reliable.'"
Comment: Nice to know a definite estimate. And remember the Milky Way started at 1.8 billion years later
Cosmology: Einstein general theory time is relative
by David Turell , Tuesday, April 12, 2022, 18:39 (955 days ago) @ David Turell
Depends on motion and gravity:
https://bigthink.com/starts-with-a-bang/time-dilation/?utm_source=mailchimp&utm_med...
"No matter where you are in the Universe, time always passes at precisely the same rate for any observer: one second per second. But when it comes to how time passes at one location relative to another, both your speed and how deep inside a gravitational potential well you are affect the rates at which clocks run. As a result, there not only is no absolute time, but time passes faster at higher elevations on Earth than lower ones. From space to mountaintops to tabletops, we've measured the difference, and Einstein had it exactly right.
***
"...if you have two different clocks, you can compare how time flows under different conditions. If one clock remains stationary while the other travels quickly, the fast-moving clock will experience a smaller amount of time passing than the stationary clock: that’s the rule of time dilation in special relativity.
"What’s even more counterintuitive, however, is that the relative flow of time also depends on the difference between how severely space is curved between two locations. In General Relativity, this corresponds to the strength of gravity at your particular location, which means that your feet actually age at a different rate than your head when you’re standing up. Here’s the physics of how we know.
***
"...the laws of physics remain the same at all times and all places, and so these transitions that emit or absorb photons always occur at the same energy. However, if the emitter of a photon and the (potential) absorber of a photon aren’t located at the same time and place as one another, there’s a good chance that they won’t agree on the energies they observe.
When it’s because the objects are in relative motion with respect to one another, we know this effect as a Doppler shift.
***
"...here’s where things get weird: this same type of shift should also occur — even if everyone is stationary — when your gravitational field strength changes from one location to another.
***
"Just as you can have Doppler redshifts and blueshifts for light, you can also have gravitational redshifts and blueshifts. For example, if you send a photon from the Sun to the Earth, because the Sun’s gravitational field dominates the Solar System and is stronger near the Sun than farther away, that photon will lose energy (and become “redder”) as it travels from the Sun to the Earth. If it were to go in the opposite direction, from the Earth to the Sun, the photon would gain energy and become “bluer” in color.
***
"The overall lesson is this: for every meter of height that you gain, you need a Doppler shift of ~33 nanometers-per-second to compensate for it. It’s like being lower on the surface of the Earth requires you to be in motion at a certain rate just to have time pass at the same rate as it would if you were higher. In other words, without an extra little speed boost at your feet — without an extra amount of time dilation added in — time passes more quickly at higher elevations in Earth’s gravitational field.
"Your head, to be blunt, ages more quickly than your feet do."
Comment: God made our world counterintuitive in relativity and quantum mechanics. And folks like dhw wish to analyze God and outthink Him, complaining about what He has created and the way He did it, ignoring the factual history God created along the way. We have only a smidgeon of His mental capacity. We cannot fathom those depths.
Cosmology: gravitational waves scar spacetime
by David Turell , Friday, December 10, 2021, 20:05 (1078 days ago) @ David Turell
They leave a permanent distortion which changes information:
https://www.quantamagazine.org/gravitational-waves-should-permanently-distort-space-tim...
"The “gravitational memory effect” predicts that a passing gravitational wave should forever alter the structure of space-time. Physicists have linked the phenomenon to fundamental cosmic symmetries and a potential solution to the black hole information paradox.
"The first detection of gravitational waves in 2016 provided decisive confirmation of Einstein’s general theory of relativity. But another astounding prediction remains unconfirmed: According to general relativity, every gravitational wave should leave an indelible imprint on the structure of space-time. It should permanently strain space, displacing the mirrors of a gravitational wave detector even after the wave has passed.
"Since that first detection almost six years ago, physicists have been trying to figure out how to measure this so-called “memory effect.”
“'The memory effect is absolutely a strange, strange phenomenon,” said Paul Lasky, an astrophysicist at Monash University in Australia. “It’s really deep stuff.”
"Their goals are broader than just glimpsing the permanent space-time scars left by a passing gravitational wave. By exploring the links between matter, energy and space-time, physicists hope to come to a better understanding of Stephen Hawking’s black hole information paradox, which has been a major focus of theoretical research for going on five decades. “There’s an intimate connection between the memory effect and the symmetry of space-time,” said Kip Thorne, a physicist at the California Institute of Technology whose work on gravitational waves earned him part of the 2017 Nobel Prize in Physics. “It is connected ultimately to the loss of information in black holes, a very deep issue in the structure of space and time.”
***
"According to the memory effect, after the passing of the wave, the circle should remain permanently deformed by a tiny amount. The reason why has to do with the particularities of gravity as described by general relativity.
***
“'The memory is nothing but the change in the gravitational potential,” said Thorne, “but it’s a relativistic gravitational potential.” The energy of a passing gravitational wave creates a change in the gravitational potential; that change in potential distorts space-time, even after the wave has passed.
***
"...space-time has the potential to store information, which could be the key to solving the infamous black hole information paradox. Briefly, the paradox is this: Information cannot be created or destroyed. So where does the information about particles go after they fall into a black hole and are re-emitted as information-less Hawking radiation?
"In 2016, Andrew Strominger, a physicist at Harvard University, along with Stephen Hawking and Malcolm Perry realized that the horizon of a black hole has the same supertranslation symmetries as those in asymptotically flat space. And by the same logic as before, there would be an accompanying memory effect. This meant the infalling particles could alter space-time near the black hole, thereby changing its information content. This offered a possible solution to the information paradox. Knowledge of the particles’ properties wasn’t lost — it was permanently encoded in the fabric of space-time.
***
"Lasky and Schmidt have independently predicted that they’ll need over 1,000 gravitational wave events to accumulate enough statistics to confirm they’ve seen the memory effect. With ongoing improvements to LIGO, as well as contributions from the VIRGO detector in Italy and KAGRA in Japan, Lasky thinks reaching 1,000 detections is a few short years away."
Comment: So a black hole does not destroy information. That may solve the information paradox related to black holes. dhw should be willing to wait for research results, but unfortunately he isn't and constantly complains about God's deeds before they are understood..

Reblak’s three posts constitute a detailed account of the argument against red shift and hence the theory of the Big Bang and the expanding universe. He also recounts the sordid history of how the scientific establishment has vilified its opponents, and has attempted to cover up or distort the evidence against its own theories. This is a very important contribution to our discussions. Having been a long-standing member of the Society for Interdisciplinary Studies (though I resigned some time ago for reasons I shan’t go into here), I am familiar with much of the material but as a non-scientist am in no position to pass judgement on the science itself. I can only say that the arguments are sufficiently persuasive to bolster my philosophical doubts about the Big Bang and expansion. In this post I shall therefore only discuss the non-specialist points Reblak makes at the beginning. I would like however, to express my gratitude for this most informative account.
DAVID's comment: Inflation explains much of why the universe looks as it does, but not without problems. A cyclic universe gets rid of the origin problem but keeps the Big Bang. It also gets rid of the multiverse. A cyclic universe doesn't get rid of a first cause.
dhw: Reblak has mentioned the redshift problem too, and perhaps he will explain this in more detail.
On this forum, we have repeatedly discussed the unanswerable question of what preceded the Big Bang if the Big Bang ever happened. The concept of eternal energy and matter as first cause would allow for any number of universes before this one, or for this one itself being eternal and constantly changing.
reblak: A cyclic Universe may well be a good suggestion and reflects somewhat my own view. How this cycle works is totally unknown. Proponents of other multiple universe ideas totally fail to accept that as Matter is unconscious it must work in accord with existing intrinsic universal physical law.
What is knowable is that there is no ‘first cause’. Eternity doesn’t include first causes! Everything has always existed, on and off, at different times and circumstances. In our perfect Universe, conditions at any point denote outcomes. Its inherent capacity allows any and every possible variation over time.
I regard ‘first cause’ as a philosophical con trick. The philosopher thinks of a logically convincing term and then develops it to fit his theories, so when someone opposes the theories, he can accuse them of defying the logic of the term. ‘Intelligent design’ is another such device. Your own theory is simply a different ‘first cause’ from Aquinas’s God - namely, an eternal (= always existed), ever changing “everything”/universe/combination of energy and matter, as I indicated above in the comment you quoted.
reblak: What it may include is an ongoing process of collapse and regeneration. That behaviour may possibly occur as a result of widespread supernovas. We may never know the definite truth. Such regeneration may entail a ‘rolling’ effect that is always afoot from place to place throughout the Universe. However, there can be no change in the actual makeup. The ‘laws’ have no capacity for change. An automatic process cannot change – it is immutable!
This is a problem for me. What laws, what “automatic process”, can account for the appearance of living cells capable of evolving from bacteria into the complexities of conscious human beings? I raised this question before, and drew your attention to a certain form of panpsychism that tied in with some of your ideas, but you never responded. Evolvable life and consciousness (in all its manifestations) for me are two major stumbling blocks to acceptance of atheistic materialism. (NB non-acceptance is not the same as rejection, which applies equally to my views on theism).
reblak: This process thereby totally precludes any pre-existing form of Universe. Such a view is a grossly misguided failure to understand that we have already a perfect Universe. Were it imperfect it would never have existed.
See below for a pre-existing form. I find your belief in an eternal universe very acceptable, but “we may never know the definite truth” applies to most aspects of our discussions! I am bewildered by your reference to “perfection”. I have asked you about this before, but you never answered. There are no criteria for you to judge by. What, for instance, would you regard as perfect about a comet smashing into Planet Earth and destroying every living thing? The universe is what it is and does what it does, and that’s all we know. Why muddy the waters with indefinable "perfection"?
reblak: This factor removes any possibility of any Big Bang or its attendant Black Holes and invisible Dark Fairies. Any re-formation absolutely must occur only within pre-exist [now also current] universal physical laws.
But an ongoing process of collapse and regeneration ties in with a cyclic universe, which you say somewhat reflects your own view. How does this remove the possibility of a “pre-existing form of Universe” or even a Big Bang? Doesn’t it simply mean that instead of new universes starting from scratch, you have one universe changing itself into another, as I suggested before?
Once again, I must stress that I greatly appreciate the rest of your post, and the above relates only to those aspects that I feel able to discuss and would like to see clarified.

Reblask: It seems to me, not surprisingly perhaps, that atheism presents an unambiguous view of nature. Together with the extension of its logic in considering the state of ‘matter’ and other basic configurations, I suggest that following the path it sets will be the preferred choice for a rational thinker.
In this sense, a 'rational thinker' is one who seeks logical advances that employ no help from a 'superpower'.
Right here, you lost me. By classifying a 'rational thinker' as only people who agree with you, you label anyone that disagrees with you as 'irrational', i.e. thinking without reason or rational thought. Yet, as a theist, I HAVE a rational, reasoned approach to my belief in God, and that belief is formed much like our belief in gravity. We can not measure it directly, but we can measure the indirect evidence and follow the
Reblask: In support of my view, I make the following points:
1. This first point is absolutely fundamental. The Universe is composed of the material we call ‘Matter’.
2. Matter can be neither created nor destroyed. There is nowhere for Matter to come from or ‘disappear’ into.(Bold Italics mine)
3. On this point, if you fantasise(sic) some other place, you face only more problems! Where is this other place? How does the Matter become destroyed? How then does it get fed into that ‘other place’? But - It still hasn't ‘disappeared'. It lives on in some invented ‘other place’!
Your logic fails here. You talk about matter not 'disappearing', but ignore the more fundamental question of how did it appear from nothing if it can neither be created nor destroyed? If you fantasize that it comes from nowhere and from nothing, you only face more problems.
(...blah blah nothing can disappear and you are crazy irrational if you think it does.. blah blah..)
Reblask: 5. This conclusion, viewed now (by me) as a certainty, indicates that no superpower has any useful place in the Universe nor is it needed. Considering it at all, from a research angle is a complete waste of time. as it leads nowhere other than to yet another cosmological gum tree!
These considerations make a nonsense of gods etc., exposing these superstitions for what they are – superstition.
6. This allows us to consider ideas in a rational and logical manner. The Big Bang proposes that our present Universe manifested itself, theoretically, from ‘another outside universe’ that was able to invest all the Matter necessary to constitute our present Universe into a miniscule point called a Singularity. No information on how this can be achieved...
...
8. It is a shame (for me) that space on this site limits the length and breadth of my case which will later include web references that further support the case against the shoddy ‘science’ that presents supposition, unsupported by real evidence, as proven fact. Outrageous abuse of position and authority. The underlying motive force is (of course) money and professional position in a greedy world.
Site limits don't matter. As it currently stands, this argument is still born because you can not explain the existence of matter or energy that 'can neither be created nor destroyed'. It had to come from somewhere, no matter how many regressions you make.

What is the purpose of living? How about, 'to reduce needless suffering. It seems to me to be a worthy purpose.

For your better understanding, I would say, (were I religious) that God created the Universe just as it is, with its own logic and knew that humanity would eventually emerge.

‘My’ Godhead would need no aid nor human toadying worship. For believers, a major downside to this is that an incredibly Almighty God is allowing monstrosities to be committed by humans in his name and permitting nonsenses such as freewill (a purely human invention) to be presented as an excuse to explain ‘His’ inaction. The reality is that all the above is simply us transferring some of our human, rather nasty behaviour, into the mind and behaviour of a being who, if he exists, is way, way, beyond our understanding.
An Almighty who does not know as much as I do of the nature of humanity (which ‘He’ ostensibly created!) falls a long way short of being Mighty, let alone ‘Almighty’!

How delightful to meet someone who despite the gulf between our different views of religion, sees so clearly the direction of my thinking - and agrees - all the way to a final point, where we each favour an alternative solution. Thank you again, you have cheered me up when I was beginning to think that no-one would understand what I am trying so hard to make clear!

Forgive my intrusion, but firstly I don’t see why we must choose (what happened to open-mindedness?), and secondly I don’t see why the existence of God and the language of physics should be a “one or the other” choice: if God exists, could he/would he not have used the language of physics, chemistry and biology his “wonders” to perform?

Hello dhw
Very happy to see your input – the more the better ! Unfortunately, as is so often the case, my remarks are misread or misunderstood (presumably I am at fault in some way).
You posted this
“Forgive my intrusion, but firstly I don’t see why we must choose (what happened to open-mindedness?), and secondly I don’t see why the existence of God and the language of physics should be a “one or the other” choice: if God exists, could he/would he not have used the language of physics, chemistry and biology his “wonders” to perform?
My answers are:
The question of choice must always be a personal decision. However – ‘sitting on the fence’ has little appeal for me – one gets stabbed by too many unwanted metaphorical splinters that way! I take the view that, from any standpoint, where in the course of research one avenue seems more likely than the other/s, my mental energy is going to be concentrated more on the one than any other. Note that I say ‘more’- not entirely.
The alternative is to sit back and wait upon the views of others. I do that as well! Choice!
Your second point:
“... if God exists, could he/would he not have used the language of physics, chemistry and biology his “wonders” to perform?
In my post I made very clear my position on this. I wrote:
For your better understanding, I would say, (were I religious) that God created the Universe just as it is, with its own logic and knew that humanity would eventually emerge.
I mentioned somewhere else that if God created the Universe, it is - must be - perfect. I have no belief (in this regard) other than in the efficacy of Mother Nature and am utterly, immovably convinced that the Universe is totally and absolutely perfect. Its very perfection precludes – in my perception of logic – any ‘previous configuration’ at all. The Universe functions entirely within its 'rules of engagement' and these particular 'rules of engagement' are all embracing and cannot be modified or disregarded in any manner.
Whilst there is a multiplicity of other cast iron reasons for dismissing Big Bang theory, on this basis alone I feel fully justified in claiming that the whole Big Bang philosophy is, to coin a phrase, “Up the pictures!”
While there is insufficient space left to say as much as I would like I will content myself with what there is.
The scientific establishment has generated their opinion on the basis of one unproven assumption, that redshift displays as evidence that the Universe is expanding and that therefore it must have evolved from another Universe, after taking the form of a tiny Singularity (into which our entire Universe had been compressed).
The Singularity goes on to expand with incredible power into a cloud of ‘gases’ for about 400 millions of years, then finally, (bored stiff of condensing into solid stars or whatever), it gears itself up and springs into action, racing out into empty (???!!!) ‘space’ for around some 13.5 billion years, in every direction, at absolutely astonishingly speed. Again, this fantastic, inexplicable rate is forced on them so as to ‘explain’ their now assumed distance, in the time allowed. Presumably, galaxies were built en route as there are millions of them.
This raises the question of Matter being continually produced from nowhere!
“And now, ladies and gentlemen, in my next trick, a real execution by guillotine, you will notice that at no time does my head leave my neck!” Impossible, you say? No no! I am a Cosmologist!
What our own galaxy was doing for the putative billions of years, is carefully avoided.
Despite their agreeing that ‘obviously’ the chances of our being at the centre of this Universe are remote to the point of absurdity, they claim that in all ‘directions’ the farthest stars are ‘reshifted’ and at similar distances!
Eh! But ‘they’ agree that we are not in the middle!
If this (virtually a certainty) is so, the redshift cannot possibly be (at every whichway) the actual ‘edge’ of the Universe. What we cannot ‘see’, as it were, behind us, must be a lot more Universe! This of itself makes conclusions about the age of the Universe totally uncertain and purely speculative.
On top of these few pointers, those who propound this utterly irrational scenario can offer absolutely no vestige of evidence nor reasonable hypothesis. They resort to the (undeniable) fact that we can know nothing of something that pre-existed our Universe!
Yet, here they are, inventing a wholey different Universe, packed with Dark Matter, Black Holes etc, ad Infinitum, all because their potty ideas keep falling apart without them! Black Holes became necessary to invent a way to increase the power of gravity when they realised that the Big Bang would not work with true gravity being the weakest known force.
The phenomena they propound as ‘evidence’ can all be explained by the use of known physical laws and effects. What appears to be their problem is the result of an apparent determination to see what they want, not what is logically explainable in another way.

I'd like to drop in for some comments and questions.
John: This raises the question of Matter being continually produced from nowhere!
Matter and energy are two aspects of the same thing. The universe is filled with energy.
John: What our own galaxy was doing for the putative billions of years, is carefully avoided.
Our galaxy is thought to be 5 billion years old and has organized since then into its spiral arms.
John: If this (virtually a certainty) is so, the redshift cannot possibly be (at every whichway) the actual ‘edge’ of the Universe. What we cannot ‘see’, as it were, behind us, must be a lot more Universe! This of itself makes conclusions about the age of the Universe totally uncertain and purely speculative.
What is your opinion of the cosmic microwave background which has been carefully studied by the Planck satellite as a remnant of the Big Bang?
John: Yet, here they are, inventing a wholey different Universe, packed with Dark Matter, Black Holes etc, ad Infinitum, all because their potty ideas keep falling apart without them! Black Holes became necessary to invent a way to increase the power of gravity when they realised that the Big Bang would not work with true gravity being the weakest known force.
When the LIGO found, more than once, colliding black holes gravitational waves, did you believe the results?
John: The phenomena they propound as ‘evidence’ can all be explained by the use of known physical laws and effects. What appears to be their problem is the result of an apparent determination to see what they want, not what is logically explainable in another way.
Didn't scientists find those 'known physical laws'? How did they lose their way?

I must also thank both you and BBella, as I fear my own welcome may have seemed a little ungracious. I also agree with a lot of what you say, but on this forum we all tend to focus on matters where there is disagreement. This should never be taken personally, and sometimes it does lead to greater clarity even if not to agreement. That may be the best we can hope for!
dhw: Forgive my intrusion, but firstly I don’t see why we must choose (what happened to open-mindedness?), and secondly I don’t see why the existence of God and the language of physics should be a “one or the other” choice: if God exists, could he/would he not have used the language of physics, chemistry and biology his “wonders” to perform?

Undoubtedly choice is a personal decision. Once you have taken your choice (atheism), of course you will concentrate your energy more on proving that your choice was right. David, one of our theists, follows the same principle, but I’m pleased to note that like him you are prepared to consider the views of others.
Reblak: Your second point:
“... if God exists, could he/would he not have used the language of physics, chemistry and biology his “wonders” to perform?” In my post I made very clear my position on this. I wrote:
For your better understanding, I would say, (were I religious) that God created the Universe just as it is, with its own logic and knew that humanity would eventually emerge.
You also wrote that our ignorance of how life came about “gives no credence to engaging some sort of magic (God) as being the solution", and that we must choose between “the unquestionable will/act of God” and a full explanation in the language of physics”. (My bold.) I don’t see why you can’t have both (no magic involved) since they are perfectly reconcilable. Forgive me, but your views on what a possible God may have done, or known in advance, is hardly an answer.
Reblak: I mentioned somewhere else that if God created the Universe, it is - must be - perfect. I have no belief (in this regard) other than in the efficacy of Mother Nature [...]
I see no difference between God creating perfection and Mother Nature creating perfection. A pantheist is still a theist. (I wonder what the criteria are for perfect universes, but let that pass.) The split occurs if you tell us Mother Nature is an impersonal and unconscious force which works automatically according to the laws of matter. David bombards us with articles describing the complexities of our biology (there are two more today), you have admitted that “there is nothing that we know of that can explain how life came about”, and I have pointed out that despite our own conscious intellect, we still cannot create a living being from scratch. And yet you believe that living beings can be produced by an impersonal and unconscious force which works automatically. That, in my view, requires a great deal of faith (which I define as strong belief without evidence, and hence irrational), and it is a major reason why I continue to sit on my fence, which I can assure you is not at all painful!
Reblak: Its very perfection precludes – in my perception of logic – any ‘previous configuration’ at all. The Universe functions entirely within its 'rules of engagement' and these particular 'rules of engagement' are all embracing and cannot be modified or disregarded in any manner.
Most theists would probably agree with the last part of this statement but would argue that the “rules”, just like biological complexity, denote design. I don’t have a problem with atheist arguments concerning faith in some supernatural being, but I do have a problem with faith in the astonishing inventive powers of an unconscious Mother Nature. You have not yet commented on the third, panpsychist hypothesis I have proposed.
You have devoted the rest of your post to once more debunking the Big Bang theory, and as I myself am sceptical about it and take very seriously both your own and Tony’s (balancemaintained) scientific arguments, I shan’t make any further comment. Tony, incidentally, is a theist, so the Big Bang theory has nothing to do with the question of whether there is or isn’t a God.

Sadly, I tend to lose track of which post is which. Used to have a memory like a steel trap, but at 86 it just isn't so. I have saved my answers but can't find the questions! I like to write in Word where I can usually save stuff OK. When I punt around, the question (it seems to me!) has become lost somewhere in the fantastic threads you manage!
I am very keen to continue using your site and it is important (to me) that I maintain the highest ethics in correspondence. Just saying this so you know why sometimes your points may seem to have passed unregarded.
I have few, if any inhibitions, having served as a uniform PC at Bow Street, Greys Inn Road and West End Central until my promotion to Sergeant in 1959. I then spent 7 action filled years at the long closed Commercial Street station (Brick Lane, Jack the Ripper and the insane Kray twins - plus a whole lot more violence, scumbags etc. Thousands of busy bustling people with pickpockets abounding in Petticoat Lane and Spitalfields market - I think they are all gone now. That is enough about me at this point anyway.
Coming to your points: I don’t see why you can’t have both (no magic involved) since they are perfectly reconcilable. Forgive me, but your views on what a possible God may have done, or known in advance, is hardly an answer.
A theist may have both, but an atheist cannot. Here I must say that my comment is being mangled a bit. My remark was just about as hypothetical as my atheism can get in trying to give some sympathetic understanding of a sensible religious belief. Were I to embrace religion at some point that would quite probably reflect my then belief.
Perfection is ‘perfect’ regardless of its origin. The baseless imagining of criteria for ‘perfect Universes’ is, frankly, very silly. This sort of ‘diversionary’ suggestion should live only in science fiction. Nothing ‘wrong’ with enjoying impossible tales but they have no place in a reasoned discussion.
Our Universe must, unavoidably, be accepted as perfect because there is no possible way we can genuinely and honestly, even in imagination, envisage an alternative – we have absolutely no ‘criteria’ for this whatsoever. You can talk until the cows come home but that is the ‘everything’ of what you can do! If you think I am closing the door on that issue, you are 100% right!
You, of course, may open any door you choose, but I see no prospect that I would follow.
“ And yet you believe that living beings can be produced by an impersonal and unconscious force which works automatically”.
Of course I do! The only force known in absolutely any form of creation are the acts of what I, rather lovingly, denote as Mother Nature. Whilst I am open to consideration of future possible discoveries, they will not be found by illogical imagination.
Until some properly evidenced discovery is made logic suggests that Mother Nature does it alone and unaided by any other than the known laws of our rather marvellous Universe.
The ‘rules’ operating our Universe are simply the intrinsic effects of a complex but complete unity. The presence of an author is neither needed nor possible. We get hooked up on a fantasy treading that path.
There are indeed no ‘rules’ as such. The ‘rules’ we speak of are purely human descriptive inventions, explaining how things work in terms we can understand and use to accomplish what we may wish to do – nothing more.
You have admitted that “there is nothing that we know of that can explain how life came about”, and I have pointed out that despite our own conscious intellect, we still cannot create a living being from scratch.
Thank you for pointing this out. This was a mistake in presentation. Our present abilities reflect the level of our present society. That has so very little to do with our potential capabilities.
Yesterday only birds could fly – need I say more?
You decry faith, cracking on that it bespeaks an irrationality. In some cases that is so, but I declare that if it is entirely dependent on already established fact, it is a totally rational premise and - this type of faith - is often rewarded with (sometimes) irrefutable proof thus demonstrating that particular faith as having been rational in the first place!
A last point: the Big Bang, contrary to your suggestion, is – consciously or unconsciously – a product of the religious tendency imbued into the Royal Society by Sir Isaac Newton during his 20 years reign as President. To be more than a ‘possibility’ it requires the intervention of a God’s almighty powers, overturning all known physical laws. This is reflected in the superstitious idea that there may be ‘something’ out there.
The leading scientist of his day, Sir Fred Hoyle (of Steady State theory) was blackballed because of his publically avowed atheism. Were it otherwise, he would have acceded to President of this religion dominated Society.

May I suggest, then, that you save the questions as well! Thank you for your very interesting biography, and your willingness to engage in debate. On a formal point, when you are quoting other people, would you please put the quotes in italics. Otherwise, it’s very difficult for readers to know who said what. As follows:
dhw: I don’t see why you can’t have both (no magic involved) since they are perfectly reconcilable. Forgive me, but your views on what a possible God may have done, or known in advance, is hardly an answer.
Reblak: A theist may have both, but an atheist cannot.
You had said that “we must choose between the unquestionable will/act of God” and a “full explanation in the language of physics”. That implies the two are incompatible, and they are not. Obviously someone who has made up his mind that there is no God will not “have” God, but that does not mean the rest of us “must choose” between God and science.
You wrote that you were “immovably convinced that the Universe is totally and absolutely perfect”. Now you say “The baseless imagining of criteria for ‘perfect Universes’ is, frankly, very silly.” And “Our Universe must, unavoidably, be accepted as perfect because there is no possible way we can genuinely and honestly, even in imagination, envisage an alternative – we have absolutely no ‘criterion whatsoever.” I’m afraid I can see no connection between “perfection” and our inability to envisage an alternative. If there are no criteria, why bother to talk of “perfection” at all? What is your point in doing so?
Dhw: And yet you believe that living beings can be produced by an impersonal and unconscious force which works automatically”.
Reblak: Of course I do! The only force known in absolutely any form of creation are the acts of what I, rather lovingly, denote as Mother Nature. Whilst I am open to consideration of future possible discoveries, they will not be found by illogical imagination.
Until some properly evidenced discovery is made logic suggests that Mother Nature does it alone and unaided by any other than the known laws of our rather marvellous Universe.
You use the term “Mother Nature” just as theists use the term “God”, to explain everything, but this simply makes you into a pantheist. What you actually mean is that a blind, unconscious, unthinking force automatically “does it alone”. But so far the only arguments you have offered for this irrational faith are that you don’t believe in God, and that one day you will be proved right. (See the next point:)
Dhw: You have admitted that “there is nothing that we know of that can explain how life came about”, and I have pointed out that despite our own conscious intellect, we still cannot create a living being from scratch.
reblak: Thank you for pointing this out. This was a mistake in presentation. Our present abilities reflect the level of our present society. That has so very little to do with our potential capabilities.
In other words, you have faith that with our wonderful intellect we humans will eventually crack all the codes, and what will that prove? Only that it requires a wonderful intellect to crack the codes. And how does that prove that you don’t need any intellect at all to create the codes?
Reblak: The ‘rules’ operating our Universe are simply the intrinsic effects of a complex but complete unity. The presence of an author is neither needed nor possible. We get hooked up on a fantasy treading that path.
Of course you don’t need an author if you have irrational faith that the complexities of life can be created by an unconscious force that hasn’t a clue what it is doing. But I agree that belief in a sourceless eternal consciousness also requires irrational faith. Fortunately, we are not compelled to choose between two irrational faiths, but are blessed with the alternative of keeping an open mind.
Reblak: You decry faith, cracking on that it bespeaks an irrationality. In some cases that is so, but I declare that if it is entirely dependent on already established fact, it is a totally rational premise and - this type of faith - is often rewarded with (sometimes) irrefutable proof thus demonstrating that particular faith as having been rational in the first place!
We are talking specifically about faith in a supernatural being and faith in blind, unconscious Mother Nature being capable of designs which are so complex that we highly conscious humans cannot explain, let alone replicate them. Both faiths “depend on” an already established fact – namely, that life exists. It is belief in one particular explanation, not the fact, that requires irrational faith.
reblak: A last point: the Big Bang, contrary to your suggestion, is – consciously or unconsciously – a product of the religious tendency imbued into the Royal Society by Sir Isaac Newton during his 20 years reign as President. […]
There are now thousands of scientists who believe in the Big Bang theory, and you know as well as I do that they are not all theists! Just like evolution, the theory is open to theistic and to atheistic interpretation, and both sets of proponents twist it to their liking.
Cosmology: space is quantum foam
by David Turell , Tuesday, August 08, 2017, 18:27 (2663 days ago) @ dhw
Virtual particles are everywhere is what research has found. It is a false vacuum, not a true vacuum with important implications for the physics of the universe:
https://www.livescience.com/60053-is-space-full-of-quantum-foam.html?utm_source=ls-news...
"Quantum physicists aren't average people, however. Armed with theoretical microscopes, they keep on magnifying, gazing deeper and deeper into empty space until out of nothing, they suddenly see something.
"That something is a roiling collection of virtual particles, collectively called quantum foam. According to quantum physicists, virtual particles exist briefly as fleeting fluctuations in the fabric of spacetime, like bubbles in beer foam.
"'The 'bubbles' in the quantum foam are quadrillions of times smaller than atomic nuclei and last for infinitesimal fractions of a second—or in 'quantum-speak', the size of a Planck Length for a Planck Time," Eric Perlman, a Professor of Physics and Space Science at Florida Institute of Technology, says.
"Something so utterly small has obviously not been directly observed. So why can we be very sure this quantum foam exists? One of the greatest pieces of evidence for it was predicted back in 1947 by Dutch physicists Hendrik Casimir and Dirk Polder. Fermilab senior experimental physicist Don Lincoln explained the so-called "Casimir Effect" for PBS:
"If the quantum foam was real, they reasoned, then the particles should exist everywhere in space. Further, since particles also have a wave nature, there should be waves everywhere. So what they imagined was to have two parallel metal plates, placed near one another. The quantum foam would exist both between the plates and outside of them. But because the plates were placed near one another, only short waves could exist between the plates, while short and long wavelength waves could exist outside them. Because of this imbalance, the excess of waves outside the plates should overpower the smaller number of waves between them, pushing the two plates together. Thirty years after it was first predicted, this effect was observed qualitatively. It was measured accurately in 1997.
"The idea that space is, at its very foundation, a frothy, chaotic mess has huge ramifications for our understanding of the universe.
"'It is on such short distance scales that we encounter the fundamental incompatibility between general relativity and quantum mechanics," string theorist and Columbia University professor Brian Greene wrote in his book The Elegant Universe. "The notion of a smooth spatial geometry, the central principle of general relativity, is destroyed by the violent fluctuations of the quantum world on short distance scales."
"Thus, conclusively demonstrating that quantum foam does or does not exist would be very useful in sorting out the true nature of reality. But, as happens frustratingly often in science, recent experiments disagree. A possible way to test for the presence of quantum foam is to measure how long it takes photons erupting from stellar explosions to travel great distances. If spacetime is flat and boring, two photons ejected from the same source should take the same time to travel a set distance. But if spacetime is foamy, then one photon might get slowed by the slight perturbations. A 2009 analysis found that high-energy and low-energy photons from the same gamma-ray burst arrived at a set location at different times, but two subsequent analyses of other bursts showed little to no variance, indicating that spacetime is smooth, or at least not as foamy.
"None of the experiments, however, can measure with fine enough detail to rule out quantum foam on the tiniest of scales. We might just have to wait for a microscope that can see down to 1.6 x 10^-35 meters – the Planck length – to be certain, and constructing such a device would be a tall task indeed."
Comment: Note the article says there is indirect proof in 1997, but no direct proof since. Quantum gravity theories, an attempt to combine general relativity and quantum theory, depends upon the interpretation of space as foamy filled with virtual particles. The basis of our reality is quantum mechanics. God likes to work in mysterious ways.
Cosmology: Latest theories of everything

May I drop in to comment, the Big Bang Theory, is the result of running the expanding universe backward, according to Einstein's general relativity theory, and he was agnostic, not theistic. If the universe had a starting point, we still cannot have any idea what came before the BB as a first cause, but it must be something, and not quantum fluctuations, because that just takes us back to one further preceding step.
Cosmology: universe not lumpy
by David Turell , Tuesday, August 08, 2017, 19:03 (2663 days ago) @ David Turell
The latest mapping of the universe shows that lumpiness is not present:
https://www.scientificamerican.com/article/cosmic-map-reveals-a-not-so-lumpy-universe/?...
"The new results, part of the ongoing Dark Energy Survey (DES), charted the distribution of matter in part by measuring the way that mass bends light, an effect known as gravitational lensing. The Universe was extremely smooth, with matter evenly distributed in its infancy nearly 14 billion years ago, but mass has been clumping together ever since into galaxies, gas clouds and other structures. Data released by the DES team on August 3 suggest that the clumping has happened more slowly than indicated by earlier estimates, which were based on baby pictures of the Universe made by measuring the cosmic microwave background, the afterglow of the Big Bang.
"The difference in the results produced by the two techniques is still within the margins of error in both sets of measurements, say the survey leaders. A smaller gravitational-lensing survey, the Kilo Degree Survey (KiDS) also found a similar discrepancy last year.
"Either way, the results show that DES is now reaching levels of precision that make it competitive with microwave-background surveys—including those by the European Space Agency's Planck satellite — says survey leader Joshua Frieman,
***
"The latest study was based on the first year of data collection, in which DES mapped 26 million galaxies in the southern sky and measured their apparent shapes. The team then calculated the amount of gravitational lensing in each part of the sky to reconstruct the density of matter. The results confirm what has become the ‘standard model’ of cosmology, in which ordinary matter constitutes only 4% of the Universe’s contents. But the researchers find a slightly smaller amount of dark matter — about 26% — than Planck’s 29%, with the rest being taken up by ‘dark energy’, the stuff believed to be pushing the cosmos apart at an accelerating speed.
"Galaxies and dark matter are not spread uniformly across the Universe, and instead have been concentrating, under the pull of gravity, into a weblike structure of clusters and filaments, with enormous voids in between. The level of concentration measured by DES is 7% lower than what the standard model of cosmology predicts, based on Planck's data from the primordial Universe.
"If confirmed, this gap could mean that mass has been clumping at a lower pace than predicted, potentially revealing new physics. For example, it could point to unexpected interactions between dark matter and dark energy, or to new types of neutrinos.
***
"Overall, researchers are excited to have an additional tool to probe the cosmos in ever-greater detail. “My own view of all of these measurements is that they are stunning tests of the cosmological model, and the precision and accuracy only keep getting better and better,” says astronomer Wendy Freedman of the University of Chicago.
"The latest map is based on DES's first round of observation, which began in 2013, and it covers about one thirtieth of the full sky, three times larger than a preliminary map the survey released in 2015. The final survey, due to conclude in 2018, will cover one-tenth of the sky; the results might appear some time in 2020, Frieman says. Ultimately, the goal of the DES is to map a large-enough region to see how the influence of dark energy has evolved over the Universe's recent history."
Comment: The smoothness finding is in favor of the inflation theory.
Cosmology: universe not lumpy; another take
by David Turell , Tuesday, August 08, 2017, 19:52 (2663 days ago) @ David Turell
Another article with a slightly different point of view:
https://www.newscientist.com/article/2143103-new-sky-survey-shows-that-dark-energy-may-...
"The fate of the universe just became a little less certain. That’s due to a disagreement between a map of the early universe and a new map of today’s universe. If the mismatch stands the test of future measurements, we might have to rewrite physics. But that is a pretty big if.
"The new results, which are part of the ongoing Dark Energy Survey (DES), charted the distribution of matter across 26 million galaxies in a large swathe of the southern sky.
***
"It is so powerful because knowing the distribution, or clumpiness, of galaxies helps us better understand the cosmic game of tug of war as dark energy – a mysterious force that causes the universe to accelerate – pulls each galaxy apart, and dark matter – a theoretical but still unseen form of matter – pushes each galaxy together.
***
"In 2013, astronomers revealed the results of charting the universe’s dark contents across the early cosmos – 380,000 years after the big bang, to be exact – with the help of the Planck satellite.
“'We’ve had really good baby pictures of the universe and now, with this, it’s like the first time we’ve had really good selfies,” Scolnic says.
"Comparing the two allows us to piece together how the universe evolved from its early state to the present – and make predictions about the future. Many astronomers believe that dark energy is a constant force and didn’t think these results would change over time. DES’s first findings, however, might suggest otherwise.
"Take dark matter, for example. Planck pegged it at 34 per cent of the energy of the early universe, but DES finds that today it only amounts to 26 per cent. That could mean dark matter is losing the cosmic game of tug of war to dark energy – a result that would force a radical rewrite of physics.
“'If [the two different answers] don’t go away, we’re seeing the first signs of what could be a very serious problem in the cosmological model,” says David Spergel at Princeton University.
"Astronomers are hesitant to make too grandiose a claim based on the first data set. Statistically speaking, there’s only a slight tension between the results relating to today’s universe and the early universe. But Scolnic points out that this tension is one in a line of many tensions. Results from the South Pole Telescope, for example, similarly disagree with Planck.
“'It’s hard to believe that this is a coincidence,” Scolnic says. And if it isn’t a coincidence, the results could mean that dark energy actually grows stronger with time – an idea that has wild implications for our future.
"Before, we assumed that although the universe would continue to expand, galaxies would remain forever bound. But should dark energy increase with time, then one day galaxies – plus stars, planets and even the atoms within us – will also expand until they are torn to shreds.
“'That would be a disturbing conclusion,” Spergel says. But he advises against panicking just yet.
"The latest mismatch could mean that one or both of the measurements is wrong. If so, it might disappear with more data. Then again, it might not. And the fate of the universe hangs in the balance."
Comment: This DES study is in its first phases. Further study may well smooth out some the other differences with the Planck findings. Only time and more analysis will tell.
Cosmology: snowball Earth advanced life
by David Turell , Thursday, August 17, 2017, 17:42 (2654 days ago) @ David Turell
Earth had two episodes of being a giant snowball, covered with ice. The last one starting over 700 million hears ago and lasting about 60 million years set the stage for algae to appear and supply oxygen to the atmosphere:
https://cosmosmagazine.com/geoscience/how-snowball-earth-gave-rise-to-complex-life
"Now research from scientists at the Australian National University published in Nature has an answer to the when and why, dating the “rise of algae” to 659–645 million years ago. It is a surprisingly narrow interval, falling between the Earth’s second-last and last great ‘snowball’ glaciation episodes, when the oceans froze and the planet’s surface was covered in ice up to several kilometres thick.
"As much as ice-age conditions would seem inhospitable to life, the ANU research team led by Jochen Brocks and Amber Jarrett suggest the Earth’s penultimate snowball phase, known as the Sturtian glaciation, set the scene for the proliferation of algae through the grinding work of glaciers, which moved mountains into the oceans, pouring into the water a feast of mineral nutrients – notably phosphorus – that was too much for bacteria to devour. On the leftovers, in a way, did algae thrive.
"The Sturtian glaciation – the longest in Earth’s history, lasting about 60 million years between 717 million and and 660 millions years ago – is named after geological evidence unearthed from Sturt River Gorge in South Australia. This new evidence comes from Australia’s Northern Territory. The scientists analysed the ancient sedimentary rocks for molecular evidence of steroid alcohols, or sterols, which only eukaryotes can produce. They discovered a marked Increased in steroid diversity and abundance that pointed to a rapid rise of marine planktonic algae, known as archaeplastida.
“'In these rocks we discovered striking signals of molecular fossils,” says Jarrett, “We immediately knew we had made a ground-breaking discovery that snowball Earth was directly involved in the evolution of large and complex life.”
***
"Algae did not, however, conquer the oceans immediately following the end of the Sturtian. “In the post-snowball greenhouse world, tropical sea surface temperatures may have reached 50 to 60 °C, which is above the growth optimum even of extremely thermophilic algae, but well within the range of cyanobacterial picoplankton. Thus, we propose that cyanobacteria persisted in the tropics as dominant primary producers, and algae were only able to radiate once temperatures dropped after several million years.”
"Drawing on the modelling of modern planktonic ecosystems, the authors suggest the immediate response to rising phosphate probably saw cyanobacterial picoplankton densities rise to levels sufficient to sustain bacterivorous grazers, which then capped cyanobacterial cell numbers so that accessory nutrients became available for the eventual expansion of the larger algae.
"The radiation of algae, in turn, would have created a “more efficient biological pump” to drive up organic carbon and nutrients in the ocean: “We posit that permanent burial of hydrocarbon-rich algal biomass caused a step-increase in the sedimentary ratio of organic carbon to phosphorous, a key parameter ultimately controlling the net release of oxygen to the atmosphere. Thus, higher nutrient levels, a more efficient biological pump and the emergence of degradation-resistant algal biopolymers would have caused permanently increased rates of carbon burial and oxygen release to the atmosphere.”
"Says Brocks: “These large and nutritious organisms at the base of the food web provided the burst of energy required for the evolution of complex ecosystems, where increasingly large and complex animals, including humans, could thrive on Earth.'”
Comment: Obviously massive photosynthesis conversion of the Earth' atmosphere to a large porton of oxygen was crucial to the development of advanced forms of life.
Cosmology: multiverse craziness
by David Turell , Wednesday, August 23, 2017, 00:53 (2649 days ago) @ David Turell
Science should be based on evidence. String theory and multiverse proposals have no evidence at all. Shouldn't they be abandoned?
https://evolutionnews.org/2017/08/the-multiverse-is-sciences-assisted-suicide/
"Eugene Lim insisted at The Conversation in 2015 that parallel universes are science: “Whether we will ever be able to prove their existence is hard to predict. But given the massive implications of such a finding it should definitely be worth the search.” Very well, but some people research ghosts on the same basis. What makes the multiverse quest “science” but the ghost hunt “anti-science,” once evidence no longer matters as much as it used to?
"Cosmologists sense the problem and strive to rescue their multiverse from the nagging demands for evidence. Pop science media offer a window into major trends.
"One is cosmic Darwinism. Lee Smolin has advocated a cosmic version of Darwinian natural selection in which the most common universes will be those most suitable for producing black holes, as our universe does. Is Darwinism the cause? In “The Logic and Beauty of Cosmological Natural Selection” (Scientific American, 2014), Lawrence Rifkin admitted that the main problem with the hypothesis is lack of direct evidence:
"But keep in mind that from a direct evidence perspective, cosmological natural selection is no worse off at this point than proposed scientific alternatives. There is no direct evidence that universes are created by quantum fluctuations in a quantum vacuum, that we live in a multiverse, that there is a theory of everything, or that string theory, cyclic universes or- brane cosmology even exist.
***
"Physicist Ethan Siegel counsels at Forbes that we must not “doubt the Multiverse’s existence without considering the very good, scientific reasons that motivate it.” But “very good scientific reasons” are precisely what we lack, unless the term “scientific reasons” now includes immunity to “experimental and observational tests.” Similarly, physicist Brian Cox told us in 2016 that the “idea of multiverses is not too big a leap” from cosmic inflation. But he is dealing with leaps of the imagination, not of physics discoveries.
"Earlier this year, skeptical mathematician Peter Woit fretted with science writer John Horgan at Scientific American, “The problem with such things as string-theory multiverse theories is that ‘the multiverse did it’ is not just untestable, but an excuse for failure.”
Commenting elsewhere on Zeeya Merali’s A Big Bang in a Little Room (2017), he noted that she contemplates “the possibility that “string theory and inflation may be conspiring against us in such a way that we may never find evidence for them, and just have to trust in them as an act of faith.” He would describe it as “a scientifically worthless idea.”
"With a clash of world views, where to begin? Woit and Horgan assume that post-modern science is a quest to understand reality, just as traditional science has been. It is not.
"For many people today, post-modern science is more of a quest to express an identity as believer in science, irrespective of evidence. Cosmologist Paul Steinhardt got a sense of this in 2014, when he reported that some proponents of early rapid cosmic inflation “already insist that the theory is equally valid whether or not gravitational waves are detected.” It fulfilled their needs. In 2017, cosmologist George Ellis, long a foe of post-modern cosmology, summed it up: “Scientific theories have since the seventeenth century been held tight by an experimental leash. In the last twenty years or so, both string theory and theories of the multiverse have slipped the leash.”
"We have so much more data now. But it provides no evidence for a multiverse. That’s nothing unusual historically (think phlogiston and ether for great ideas that did not work). We used to just adjust. But today, increasing numbers of science-minded people demand a post-modern science that adapts to their needs. After all, we evolved to survive and pass on our genes, not to understand reality.
"As a result, many cosmologists and science writers speak as if the multiverse merely awaits routine administrative clearance to morph into textbook science, absent evidence.
Characteristically, they see themselves as fighting a conservative (fuddy-duddy) establishment which clings to a role for mere evidence.
***
"The multiverse has only ever existed, so far as we know, in the mind of man. Its most promising research programs, string theory and early rapid cosmic inflation theory, have bounced along on enthusiasm alone, prompting ever more arcane speculations for which there may never be any possibility of evidence.
"But like so many other empty ideas, the multiverse has consequences. If we accept it, we abandon the view that science deals with the observed facts of nature. We adopt the view that it tells us what we want to believe about ourselves. In other words, the multiverse is science’s assisted suicide."
Comment: On this site we will be sure to use evidence from confirmed findings only!

Thank you for this superb article! We have frequently pointed out the absurdity of unproven and unprovable theories masquerading as science, while at the same time certain scientists sneer at theism because it is an unproven and unprovable theory "prompting ever more arcane speculations" etc. Three cheers for the much maligned agnostic, who can recognize Tweedledum and Tweedledee when he sees them.
Cosmology: another type of quantum gravity
by David Turell , Thursday, September 21, 2017, 18:56 (2619 days ago) @ dhw
A new theory assumes there are quanta in space that collapse their wave function and produce gravity:
https://www.newscientist.com/article/mg23531444-600-spontaneous-collapses-may-show-how-...
"HOW do you reconcile the two pillars of modern physics: quantum theory and gravity? One or both will have to give way. A new approach says gravity could emerge from random fluctuations at the quantum level, making quantum mechanics the more fundamental of the two theories.
"Of our two main explanations of reality, quantum theory governs the interactions between the smallest bits of matter. And general relativity deals with gravity and the largest structures in the universe. Ever since Einstein, physicists have been trying to bridge the gap between the two, with little success.
"Part of the problem is knowing which strands of each theory are fundamental to our understanding of reality.
"One approach towards reconciling gravity with quantum mechanics has been to show that gravity at its most fundamental comes in indivisible parcels called quanta, much like the electromagnetic force comes in quanta called photons. But this road to a theory of quantum gravity has so far proved impassable.
***
"In quantum theory, the state of a particle is described by its wave function. The wave function lets you calculate, for example, the probability of finding the particle in one place or another on measurement. Before the measurement, it is unclear whether the particle exists and if so, where. Reality, it seems, is created by the act of measurement, which “collapses” the wave function.
***
"One solution ...is a so-called GRW model that was developed in the late 1980s. It incorporates “flashes”, which are spontaneous random collapses of the wave function of quantum systems. The outcome is exactly as if there were measurements being made, but without explicit observers.
"Tilloy has modified this model to show how it can lead to a theory of gravity. In his model, when a flash collapses a wave function and causes a particle to be in one place, it creates a gravitational field at that instant in space-time. A massive quantum system with a large number of particles is subject to numerous flashes, and the result is a fluctuating gravitational field.
"It turns out that the average of these fluctuations is a gravitational field that one expects from Newton’s theory of gravity (arxiv.org/abs/1709.03809). This approach to unifying gravity with quantum mechanics is called semiclassical: gravity arises from quantum processes but remains a classical force. “There is no real reason to ignore this semiclassical approach, to having gravity being classical at the fundamental level,” says Tilloy.
“'I like this idea in principle,” says Klaus Hornberger at the University of Duisburg-Essen in Germany. But he points out that other problems need to be tackled before this approach can be a serious contender for unifying all the fundamental forces underpinning the laws of physics on scales large and small. For example, Tilloy’s model can be used to get gravity as described by Newton’s theory, but the maths still has to be worked out to see if it is effective in describing gravity as governed by Einstein’s general relativity.
"Tilloy agrees. “This is very hard to generalise to relativistic settings,” he says. He also cautions that no one knows which of the many tweaks to quantum mechanics is the correct one.
Nonetheless, his model makes predictions that can be tested. For example, it predicts that gravity will behave differently at the scale of atoms from how it does on larger scales.
Should those tests find that Tilloy’s model reflects reality and gravity does indeed originate from collapsing quantum fluctuations, it would be a big clue that the path to a theory of everything would involve semiclassical gravity."
Comment: This means we still have to find gravitons, as the necessary quanta.
Cosmology: another predicted particle found
by David Turell , Wednesday, October 04, 2017, 22:59 (2606 days ago) @ David Turell
As part of the standard model a particle, antiparticle was found 80 years ago and is now identified:
http://bigthink.com/paul-ratner/scientists-discover-the-angel-particle-that-is-both-mat...
"A team of scientists found first evidence for the existence of a Majorana fermion, a hypothetical particle proposed 80 years ago that is its own antiparticle.
"In 1928, physicist Paul Dirac predicted that every fundamental particle has an antiparticle - a twin that has an opposite charge. If a particle and antiparticle were to meet, they would be annihilated while releasing a burst of energy. But in 1937, physicist Ettore Majorana added the prediction that a class of particles exists known as fermions, which would include particles that are their own antiparticles.
"Now the researchers from Stanford University and University of California found the Majorana fermion in a series of lab experiments on exotic materials.
***
"The fermion observed by the team is known as a “chiral” fermion as it moves in just one direction along a one-dimensional path.
The experiment that resulted in the find involved looking for a special half-speed signature of Majorana quasiparticles, which are “excitations” that come from how electrons behave in superconducting materials. While these are special entities that have some properties of particles but are not actually particles found in nature, quasiparticles are still regarded as real Majorana fermions.
"The researchers applied electricity to stacks of superconducting materials and topological insulators in a chilled chamber. A topological insulator conducts current along its surface or edges only, not through the middle. A magnet was then used to control the behavior of generated electrons as they sped along the edges of the surface. The electrons were slowed down, stopped and their direction changed. This cycle continued until the scientists identified the Majorana quasiparticles that emerged by by their unique speeds.
"The practical implications of this discovery are well in the future, with potential for use in quantum computing, where it can help overcome environmental noise. Zhang calls the newly-found particle the “angel particle,” referring to Dan Brown’s bestseller “Angels and Demons” which featured a matter/anti-matter time bomb as part of the plot."
Comment: Chalk up an other one for the theoretical particle physicists. It adds another proven part to the standard model.
Cosmology: how the universe evolved
by David Turell , Monday, October 16, 2017, 20:14 (2594 days ago) @ David Turell
The latest discovery is a combination of gravitational waves and electromagnetic waves from two neutron stars in collision, which produces a spread of heavy elements around the universe. Production of elements starts with hydrogen and then compression into the heavier elements one after another until all the original 92 are present:
https://phys.org/news/2017-10-neutron-star-smash-up-discovery-lifetime.html
"It had been theorised that mergers of two such exotic bodies would create ripples in the fabric of space-time known as gravitational waves, as well as bright flashes of high-energy radiation called gamma ray bursts.
"On August 17, detectors witnessed both phenomena, 1.7 seconds apart, coming from the same spot in the constellation of Hydra.
"'It was clear to us within minutes that we had a binary neutron star detection," said David Shoemaker, another member of LIGO, which has detectors in Livingston, Louisiana and Hanford, Washington.
***
"We witnessed history unfolding in front of our eyes: two neutron stars drawing closer, closer... turning faster and faster around each other, then colliding and scattering debris all over the place," co-discoverer Benoit Mours of France's CNRS research institute told AFP.
"The groundbreaking observation solved a number of physics riddles and sent ripples of anticipation through the scientific community.
"Most jaw-dropping for many, the data finally revealed where much of the gold, platinum, mercury and other heavy elements in the Universe came from. (my bold)
"Telescopes saw evidence of newly-forged material in the fallout, the teams said—a source long suspected, now confirmed.
"It makes it quite clear that a significant fraction, maybe half, maybe more, of the heavy elements in the Universe are actually produced by this kind of collision," said physicist Patrick Sutton, a member of the Laser Interferometer Gravitational-Wave Observatory (LIGO) which contributed to the find. (my bold)

I thought your explanation for the Cambrian was an almighty dabble of instant creation, since species appeared to spring from nowhere. But I may have misunderstood.

Cosmology: our galaxy is an oddball

Our galaxy is different from the others we observe. Our solar system differs from others. Our Earth is not like other planets. And we live here to see all of this:
https://www.newscientist.com/article/2150955-why-our-freakish-galaxy-has-got-cosmologis...
"The Milky Way remains the prime example of such cosmic populations, with astronomers able to map, in detail, the stars, gas and dust that circle the supermassive black hole at its heart. This remains central to ideas of galaxy evolution. But while many of its observed properties agree with expectations, a number do not. Prominent on this list is the population of dwarf galaxies that accompany the Milky Way in space.
"Hints of oddness have been building for years. At the end of the 1990s, theoretical models predicted that our galaxy should have thousands of orbiting dwarf galaxies, but far fewer were seen. This problem came with another: the apparent lack of large satellite galaxies orbiting the Milky Way. Astronomers concluded that the complexities of star formation in the early universe could have messed up the formation process, resulting in what we see today.
"More recently, the small number of accompanying dwarfs and the Milky Way’s companion galaxy, Andromeda, were found to lie on well-defined planes, again at odds with theoretical expectation. The physics of gas in the early universe cannot account for these, with some questioning our underlying ideas of galaxy evolution.
"Now comes the latest blow. The Satellites Around Galactic Analogs (SAGA) Survey, has muddied the waters even further, showing that the dwarf galaxies orbiting Milky Way-like galaxies beyond our group of galaxies are actively forming new stars, while our own dwarfs appear to be sedately ageing with no new stars.
"Does this mean that our local environment is somehow quiet, and not representative of the wider universe? That observations of our backyard have little to say about the vast bulk of the cosmos?
"It is too early to say for sure, but we are increasingly faced with a dilemma, as our telescopes will continue to reveal distant galaxies in more detail, and it is likely that each will be, in some way, peculiar.

We know that our galaxy allows life. But if it is likely that “each galaxy will be, in some way, peculiar”, your God must have had some reason for making ALL of them different. Can you think of a reason why he would do that, when all he really, really wanted was to produce a galaxy that would enable him to produce us? Alternatively, of course, one can argue that an infinite universe chucking its bits and pieces around for eternity would have produced an infinite number of different galaxies, and sooner or later it was bound to have come up with the right combination for life.

You have morphed the discussion into the same arguments as multiverses. It is reasonable except our universe is not dealing with an infinity of galaxies. I think the odds require that. Obviously we are here because all the conditions are correct.

We know this universe had a beginning and expanded to beyond the CMB. It therefore is limited and its galaxies are not infinite. Previously, if He has made many universes, which I don't doubt, there is probably an infinity of galaxies. I stated above 'this' universe.

A cyclical coming and going allows for an eternal universe, and unless I am much mistaken, it also allows for the CMB. You seem already to have forgotten your own theory, according to which you have no doubt that your God has made many universes and there is “probably an infinity of galaxies”.

It makes no difference to the argument. Firstly, you have not explained why you think your God created all these individually different galaxies if his aim was to produce one that would allow life (same problem as the whale and the weaverbird’s nest, if his aim was to produce Homo sapiens). Secondly, quite apart from the fact that we don’t know if THIS universe is finite or not, you can still have an infinity of cycles and galaxies, which means that eventually there is bound to be one that can meet the requirements for life. I am not saying this is so. I am merely defending the atheist case against your theistic proposal.

Agreed, but according to the article, “it is likely that each [galaxy] will be, in some way, peculiar”. So each galaxy is likely to be special. And if this is true, and if we are faced with the possibility of an infinite number of different galaxies, the odds are that eventually at least one of those different galaxies would produce the special conditions necessary for life.

Of course we don’t know. Nor do we know if there is a God. That is why we put forward all these different hypotheses, and then try to test their logic. Even you acknowledged that if your God existed, you had no doubt that he would have made many universes and so “there is probably an infinity of galaxies.” You have no idea why the universe is so big if all God wanted was to create the brain of Homo sapiens. So maybe that wasn’t all he wanted. Or maybe he isn’t even there.

The Milky Way dose not look like the other ones we see:
https://www.nature.com/articles/d41586-018-07591-8?utm_source=briefing-dy&utm_mediu...
"... as the menagerie of young planetary systems grows, researchers are struggling to square their observations with current theories on how our Solar System and others formed. Such ideas have been in turmoil ever since astronomers started discovering planets around distant stars — a list that now numbers in the thousands. The Solar System has rocky planets near the Sun and giant gas balls farther out, but the panoply of exoplanets obeys no tidy patterns. And the rule book for world-building is getting more complicated as researchers find evidence of planets in the process of being born. Still, astronomers hope that witnessing such birth pangs will shed light on how all planetary systems, including our own, came to be. “We see all kinds of structure in these disks, even at very young ages,” says Follette. “Even younger than we classically thought planets should form.”
***
"As if theorists did not already have enough to grapple with, observations of planetary nurseries continue to pile up. The latest findings lend weight to the idea that planets are forming early in the lives of their stars, and at distances from them that vary widely.
"And it’s not just ALMA that’s been supplying images. Astronomers have also turned to the SPHERE instrument mounted on the ESO’s Very Large Telescope. This, too, is in the Atacama desert, about a six-hour drive south of ALMA. SPHERE has a system that can cancel out the blurring effects of the atmosphere and a filter that blocks starlight. In April, astronomers announced that they had used it to capture a diverse array of disks around eight young Sun-like stars2. Some resembled wide platters, some had distinct racetrack-like ovals, and one resembled a galaxy with jets streaming from its centre. Such diversity suggests that planet-forming is a complex process yielding many possible outcomes.
***
"With the observation of protoplanetary disks still in its infancy, the full story of planet-making will probably be more complicated than anyone expects, and ideas could well be overturned and then overturned again. “Case in point, it looks like the Solar System isn’t even the most common-looking system out there. We’re a little weird,” says Clement. “It turns out there is a lot of complexity out there.'”
Comment: More of the same. Our planet is very different and very special and so is our Galaxy. God the designer/creator at work

Agreed (with my theist’s hat on). So you do think the Cambrian explosion was a dabble of instant creation. And yet you “have always stated that God uses evolution in every process”. So now we have God capable of instant creation, but the one species he really, really wants to create has to evolve in lots of different stages, and very strangely so does the whale. And all these different stages of human and whale are necessary in order to keep life going until he can produce the one species of human he really, really wants to create, which is Homo sapiens, although he is perfectly capable of instantly creating species when he feels like it.

Cosmology: fine tuning revisited
by David Turell , Tuesday, November 21, 2017, 00:29 (2559 days ago) @ David Turell
The multiverse excuse is stupid:
https://evolutionnews.org/2017/11/ids-top-six-the-fine-tuning-of-the-universe/
"The term “Big Bang” conjures images of an explosion, and usually when we think of an explosion we imagine a highly chaotic, stochastic event that destroys any order that is present rather than creating or preserving order. The Big Bang was not that kind of an “explosion.” It’s much better understood as a “finely tuned expansion event,” where all the matter and energy in the universe were expanding from an unimaginably high energy state. However, matching that energy was control and guidance through natural laws that were designed to produce a habitable universe, a home for life.
"Consider some of the finely tuned factors that make our universe possible:
"If the strong nuclear force were slightly more powerful, then there would be no hydrogen, an essential element of life. If it was slightly weaker, then hydrogen would be the only element in existence.
"If the weak nuclear force were slightly different, then either there would not be enough helium to generate heavy elements in stars, or stars would burn out too quickly and supernova explosions could not scatter heavy elements across the universe.
"If the electromagnetic force were slightly stronger or weaker, atomic bonds, and thus complex molecules, could not form.
"If the value of the gravitational constant were slightly larger, one consequence would be that stars would become too hot and burn out too quickly. If it were smaller, stars would never burn at all and heavy elements would not be produced.
"The finely tuned laws and constants of the universe are an example of specified complexity in nature. They are complex in that their values and settings are highly unlikely. They are specified in that they match the specific requirements needed for life.
"The following gives a sense of the degree of fine-tuning that must go into some of these values to yield a life-friendly universe:
"Gravitational constant: 1 part in 10^34
Electromagnetic force versus force of gravity: 1 part in 10^37
Cosmological constant: 1 part in 10^120
Mass density of universe: 1 part in 10^59
Expansion rate of universe: 1 part in 10^55
Initial entropy: 1 part in 10^ (10^123)
"The last item in the list — the initial entropy of the universe — shows an astounding degree of fine-tuning. What all this shares is an incredible, astronomically precise, purposeful care and planning that went into the crafting of the laws and constants of the universe, gesturing unmistakably to intelligent design.
" As Nobel laureate in physics Charles Townes stated:
"Intelligent design, as one sees it from a scientific point of view, seems to be quite real. This is a very special universe: it’s remarkable that it came out just this way. If the laws of physics weren’t just the way they are, we couldn’t be here at all. The sun couldn’t be there, the laws of gravity and nuclear laws and magnetic theory, quantum mechanics, and so on have to be just the way they are for us to be here.{"
"Some scientists respond, “Well, there must be an enormous number of universes and each one is a little different. This one just happened to turn out right.” That’s a postulate, and it’s a pretty fantastic postulate — it assumes there really are an enormous number of universes and that the laws could be different for each of them. One would like to get a look at the universe-generating machine responsible for this abundance. The other possibility is that our universe was planned, and that’s why it has come out so specially."

dhw: It’s good to see you defending evolution against instant creation. It is the bedrock of Darwin’s theory.
DAVID: I have always stated God uses evolution in every process.
dhw: I thought your explanation for the Cambrian was an almighty dabble of instant creation, since species appeared to spring from nowhere. But I may have misunderstood.
REBLAK: The only unquestionable certainty is that the Universe exists. As there is neither evidence nor reason to imagine the existence of a God (or other such superpower) the simple fact is that the Universe is an eternal state of being. Eternity has no beginning and no end.
Everything known (without exception) is generated by the natural forces and material substance inherent to the Universe. Whether we can or cannot yet simulate all its actions is immaterial and has no bearing whatever on its capacity to achieve.
To claim the existence of God is mere superstition. To endow this phantom with overarching power that can create something from nothing is to be party to Wizardry. If you cannot believe in the capacity of Nature (known to exist), yet acknowledge as real something that is, most decidedly, not known to exist and simply claim it has supernatural powers, well ...
To believe that you can deduce that your God chose to build the Universe a bit at a time and that you can rationally divine that choice, beggars belief!

Welcome back! We need a good dose of atheism to re-establish the balance of this website, but I wish you had addressed your post to David and not to me, as he is the theist. I am the one who stands in the middle and rejects both his certainty and yours. My scepticism in relation to your version of events is based partly on the fact that living organisms (I include single cells) are so complex that one needs faith to believe they could assemble themselves spontaneously without any form of consciousness to guide them. (A single cell is so complex that it not only lives, but can also reproduce itself, adapt itself, and in due course evolve into multiple forms of life.) If you think that Nature is conscious, you are on the road to pantheism, which can be taken as a form of theism (i.e. God is Nature). The mystery of consciousness itself compounds the problem, and I do not exclude psychic experiences from the list of mysteries I cannot solve by way of materialism. The belief that materialistic science will eventually solve them is itself a faith. But this scepticism is balanced by the argument that we do not solve a mystery by creating another mystery. “God did it” is no more acceptable to me than it is to you, and in discussion with you, I needn’t dwell on the problems associated with such a concept. David will no doubt present his case for theism, but I will happily chip in to say why my belief is beggared both by your faith in the creative powers of chance and unthinking materials and by his faith in a sourceless and seemingly limitless conscious mind he calls God. (But I know I am wrong one way or the other.)

I guess we should ignore the Big Bang. The only alternative has been a series of Bangs in which each universe has a beginning. A single universe is not eternal.
Cosmology: multiverse craziness per Peter Woit
by David Turell , Saturday, January 27, 2018, 18:50 (2491 days ago) @ David Turell
He skewers the theory again:
http://inference-review.com/article/theorists-without-a-theory
"In his essay, George Ellis does an excellent job of explaining how some highly publicized speculative claims about theories involving a multiverse have “slipped the leash” of experiment, leading this area of theoretical physics to a strange place. One where the question of what is and what is not science has become open to debate. Here I would like to argue that it is important to recognize the extent to which it is not new and subtle issues about the relation of theory and experiment that are relevant. What is going on is something much simpler: the theorists do not actually have a theory.
***
"A crude summary of the situation is that a well-defined theory exists for supersymmetric strings propagating in a fixed flat ten space-time dimensional background. This is supposed to be just one limit of a conjectural theory (M-theory) with other conjectured solutions exhibiting four large space-time dimensions. It is these conjectural solutions that are the string vacua, and our physical laws are supposedly determined by the choice of such a solution. All evidence from work on such conjectures is that the known constraints on such string vacua provide no significant predictions about observable physics.
"An actual theory of string vacua would characterize them as solutions of some equations defined on some space parametrizing string-theory backgrounds. No such theory exists. Both the space of backgrounds and the equations remain unknown. To get anything that looks like known physics, quite complex choices of background data need to be made, with no indication that one is doing anything other than producing ad hoc ugly constructions designed to match observations, but with no predictive power. While the lack of predictions from this activity is sometimes attributed to the difficulty of the calculations, the real problem is the lack of a theoretical framework capable of giving non-empty results.
***
"The inability of the multiverse paradigm to make any predictions is sometimes attributed to the measure problem: one cannot put a measure on an infinite set giving equal weight to each element. One problem here is the equal weight assumption, which is a reflection of the lack of an actual theory. A well-defined theory would, in principle, allow one to calculate what probabilistic weight to assign to each possibility in the infinite set, giving a consistent measure. Even before getting to this measure problem though, there is a much more serious problem: one does not even know what space it is that one is supposed to be looking for a measure on. One lacks a viable theory that would describe the set of possible universes—the string vacua in the string theory framework—and is thus unable to even specify the measure problem at hand, much less hope to resolve it.
"The strongest evidence for a multiverse is generally taken to be the apparently successful Weinberg argument for the anthropic explanation of the value of the cosmological constant (CC).4 Without going into the subtleties of this story, one can see here the lack of any actual physical theory. With no underlying theory in which the statistical distribution of values of the CC is calculable, an assumption is made of a flat distribution; prior to invoking anthropics, any value of the CC is equally likely. As a theory of the physics of the CC, this is effectively exactly the same as my own personal theory, which is that I have absolutely no idea whatsoever about what the physics is determining the CC, so any value is equally likely. An accurate characterization of the situation is that neither I nor those invoking the Weinberg argument have a viable theory of the physics at issue here; there’s no scientific theory to test, so no issue about scientific testability."
Comment: Rationally, a multiverse is pie in the sky. A mathmatical invention to avoid the obvious. We can only know this universe and we can measure it.
Cosmology: lots of planets out there.
by David Turell , Sunday, January 28, 2018, 22:23 (2490 days ago) @ David Turell
Some could be Earth-like but most of those are close to their suns:
https://www.nasa.gov/mission_pages/kepler/news/17-percent-of-stars-have-earth-size-plan...
"The quest to determine if planets like Earth are rare or common is taking another stride forward on the journey. Using NASA's Kepler spacecraft, managed by NASA Ames Research Center, astronomers are beginning to find Earth-sized planets orbiting distant stars. A new analysis of Kepler data shows that about 17 percent of stars have an Earth-sized planet in an orbit closer than Mercury. Since the Milky Way has about 100 billion stars, there are at least 17 billion Earth-sized worlds out there."
Could there be life?
https://www.nbcnews.com/mach/science/simple-math-shows-how-many-space-aliens-may-be-out...
"This is an uncertain business but not a new one. In 1961 astronomer Frank Drake devised a simple equation for estimating the number of "technically active" societies in our galaxy. That bit of easy math is known as the Drake Equation, and it's often said to be the second most famous formula in science (the first being Einstein's E = mc2).
"If you look up the formula online, you'll see that it takes into account the odds that there are habitable planets around other stars, the likelihood that life will arise, and the probability that biology will occasionally evolve to produce clever beings. But even without wrestling with the Drake Equation, we can use similar reasoning to gauge the plentitude of alien societies.
"We start with recent research showing that one in six stars hosts a planet hospitable to life. No, not one in a million. One in six. So let's take that number and run with it. Next we have to make a few assumptions. In particular, if you were given a million Earth-size worlds, what fraction do you think would ever beget technically sophisticated inhabitants?
'Life on our planet began quickly: random chemical activity in 350 million trillion gallons of ocean water spawned a reproducing molecule within a few hundred million years. So maybe biology doesn't need much of a goad to get started. I don't think it's unreasonable to figure that at least half of all planets suitable for life actually produce it.
***
"How how close are the nearest signaling extraterrestrials? If we're going to pay good money to fire up the warp drive and visit some bumpy-headed aliens, how far do we have to travel? Well, the average distance between stars in our part of the galaxy is 4.2 light-years (the distance to Proxima Centauri). That is, for every cube of space that's 4.2 light-years on a side, you'll find (on average) one star. Now imagine a bigger box, 2,000 light-years on a side. It will contain 100 million star boxes, and one sophisticated civilization.
"By this rough and ready calculation, the nearest aliens are probably between one and two thousand light-years away. In other words, no closer than the three bright stars of Orion's Belt. Sure, alien neighbors might be farther — or closer. But this order-of-magnitude estimate tells us that they're not next door. They haven't heard our news reports, and they're not likely to have any incentive to visit. They simply don't know we're here.
"By the way, we probably aren't going to visit them either. Today's fastest rockets would take at least 20 million years to get there, by which time you're going to be awfully tired of on-board pretzels.
"Yes, the aliens are likely around, and 10,000 societies could inhabit our galaxy (not to mention those other galaxies!) They're not close. But they may be discoverable. That's why we continue to search the sky for radio signals launched into the ether long ago by our cosmic brethren."
Comment: We are not likely to contact any of them, but if they sent out signals thousands of years ago we might hear from them.
Cosmology: what the CMB reveals
by David Turell , Tuesday, January 28, 2020, 18:46 (1760 days ago) @ David Turell
It includes estimates of dark matter and dark energy:
https://www.quantamagazine.org/how-the-cosmic-microwave-background-reveals-the-universe...
"The team announced their first results in February 2003. Their map of the “cosmic microwave background” (CMB), which they refined in subsequent years, indicated that the familiar matter of planets, gas and stars makes up just 4.6% of the cosmos, while unseen dark matter comprises 24%. The remaining 71.4% of the cosmic pie chart had to be dark energy, which is thought to infuse the fabric of space itself. The numbers changed only a little when WMAP’s successor, the Planck satellite, took an even sharper image of the CMB 10 years later.
***
"No one has identified dark matter particles, yet the CMB reveals the large-scale behavior of the elusive substance. Ali-Haïmoud likens the situation to premodern scientists understanding buoyancy and pressure even without knowing that the chemical formula for water was H2O. Any attempt to explain away the apparent influence of dark matter, such as by tweaking the laws of gravity, will have to match the particular pulsations of the primordial fluid. No model has yet risen to the challenge.
"Dark energy, meanwhile, played a negligible role in the universe’s youth. Its presence can be inferred from the CMB’s indication that the universe is flat today. The measured quantities of dark and visible matter just don’t have the muscle to flatten space. But add 71.4% dark energy to the modern universe, and everything balances.
"This picture isn’t perfect, as recent astronomical observations have suggested that today’s universe is expanding at a faster clip than the CMB recipe implies it should be. But WMAP and Planck data have set a high bar for theorists seeking alternative, non-dark explanations for the motions of stars and galaxies. “Now that we have these detailed maps,” Dodelson said, “the CMB by itself is pretty damn good at getting almost everything.'”
Comment: The value of the CMB continues to help current theories.
Cosmology: quark gluon plasma
by David Turell , Saturday, February 01, 2020, 21:21 (1756 days ago) @ David Turell
In the very first microseconds of the universe:
https://www.sciencedaily.com/releases/2020/01/200131114737.htm
"Physicists believe that in the Universe's first ten microseconds free quarks and gluons filled all of spacetime, forming a new phase of matter named 'quark-gluon plasma' (QGP). Experimental and theoretical work at CERN was instrumental in the discovery of this hot soup of primordial matter, which is recreated today in accelerator-based lab experiments. To discover QGP in such experiments, the observation of exotic 'strange' quarks is very important. If QGP is created, strangeness is readily produced through collisions between gluons."
Another explanation:
http://www.physicscentral.com/explore/action/gluon.cfm
"A millionth of a second after the Big Bang, the universe was an incredibly dense plasma, so hot that no nuclei nor even nuclear particles could exist. The plasma consisted of quarks, the particles that compose nucleons and some other elementary particles, and gluons, the massless particles that “carry” the force between quarks (See Nuclei Knockdown). Gluons are the particles that quarks exchange as they interact, or, in the language of modern physics, gluons “mediate” the strong force between quarks. Since quarks make up protons and neutrons, this leads to the force that holds protons and neutrons together in a nucleus.
"A plasma (see Plasma Power) is an ionized gas, like the matter in a spark or a lightning bolt. But unlike these plasmas, as its name implies, the abovementioned quark-gluon plasma is made of exotic particles. Moreover, the way that quarks and gluons interact is unlike any other particles—at low temperatures and densities, they attract each other more strongly as they are separated, which explains why free quarks are not found in nature."
Comment: Plasma is like a soup. To form an organized universe, something has to guide it. Designer required.
Cosmology: gravity still unexplained
by David Turell , Monday, June 15, 2020, 19:42 (1621 days ago) @ David Turell
No answer on how it works. The curvature of spacetime is a partial explanation, no more:
https://www.quantamagazine.org/why-gravity-is-not-like-the-other-forces-20200615/
"Our current framework for understanding gravity, devised a century ago by Albert Einstein, tells us that apples fall from trees and planets orbit stars because they move along curves in the space-time continuum. These curves are gravity. According to Einstein, gravity is a feature of the space-time medium; the other forces of nature play out on that stage.
"But near the center of a black hole or in the first moments of the universe, Einstein’s equations break. Physicists need a truer picture of gravity to accurately describe these extremes. This truer theory must make the same predictions Einstein’s equations make everywhere else.
***
"We asked four different quantum gravity researchers. We got four different answers.
"Claudia de Rham, a theoretical physicist at Imperial College London, has worked on theories of massive gravity, which posit that the quantized units of gravity are massive particles:
"As one approaches the singularity at the center of a black hole, or the Big Bang singularity, the predictions inferred from general relativity stop providing the correct answers. A more fundamental, underlying description of space and time ought to take over. If we uncover this new layer of physics, we may be able to achieve a new understanding of space and time themselves.
"If gravity were any other force of nature, we could hope to probe it more deeply by engineering experiments capable of reaching ever-greater energies and smaller distances. But gravity is no ordinary force. Try to push it into unveiling its secrets past a certain point, and the experimental apparatus itself will collapse into a black hole.
***
"Daniel Harlow, a quantum gravity theorist at the Massachusetts Institute of Technology, is known for applying quantum information theory to the study of gravity and black holes:
"Black holes are the reason it’s difficult to combine gravity with quantum mechanics. Black holes can only be a consequence of gravity because gravity is the only force that is felt by all kinds of matter.
***
"Our understanding of the other forces of nature is built on the principle of locality, which says that the variables that describe what’s going on at each point in space — such as the strength of the electric field there — can all change independently.
***
"experiments confirming locality at this scale are not possible. And quantum gravity therefore has no need to respect locality at such length scales.
***
"Juan Maldacena, a quantum gravity theorist at the Institute for Advanced Study in Princeton, New Jersey, is best known for discovering a hologram-like relationship between gravity and quantum mechanics:
***
"Out of these fluctuating fields and their interactions, the vacuum state emerges. Particles are disturbances in this vacuum state. We can picture them as small defects in the structure of the vacuum.
"When we consider gravity, we find that the expansion of the universe appears to produce more of this vacuum stuff out of nothing. When space-time is created, it just happens to be in the state that corresponds to the vacuum without any defects. How the vacuum appears in precisely the right arrangement is one of the main questions we need to answer to obtain a consistent quantum description of black holes and cosmology. (my bold)
***
"Sera Cremonini, a theoretical physicist at Lehigh University, works on string theory, quantum gravity and cosmology:
"To capture these features accurately we need a new theoretical framework. This is precisely where string theory or some suitable generalization comes in: According to string theory, at very short distances, we would see that gravitons and other particles are extended objects, called strings. Studying this possibility can teach us valuable lessons about the quantum behavior of gravity."
Comment: four opinions, no answers. Note the bold and what expansion of the universe means. How does that work?
Cosmology: age of universe confirmed again
by David Turell , Sunday, July 19, 2020, 22:49 (1587 days ago) @ David Turell
Still 13.8 byo:
https://www.sciencedaily.com/releases/2020/07/200715170541.htm
"Now new research published in a series of papers by an international team of astrophysicists, including Neelima Sehgal, PhD, from Stony Brook University, suggest the universe is about 13.8 billion years old. By using observations from the Atacama Cosmology Telescope (ACT) in Chile, their findings match the measurements of the Planck satellite data of the same ancient light.
***
"'In Stony Brook-led work we are restoring the 'baby photo' of the universe to its original condition, eliminating the wear and tear of time and space that distorted the image," explains Professor Sehgal, a co-author on the papers. "Only by seeing this sharper baby photo or image of the universe, can we more fully understand how our universe was born."
"Obtaining the best image of the infant universe, explains Professor Sehgal, helps scientists better understand the origins of the universe, how we got to where we are on Earth, the galaxies, where we are going, how the universe may end, and when that ending may occur.
"The ACT team estimates the age of the universe by measuring its oldest light. Other scientific groups take measurements of galaxies to make universe age estimates.
"The new ACT estimate on the age of the universe matches the one provided by the standard model of the universe and measurements of the same light made by the Planck satellite. This adds a fresh twist to an ongoing debate in the astrophysics community, says Simone Aiola, first author of one of the new papers on the findings posted to arXiv.org.
"'Now we've come up with an answer where Planck and ACT agree," says Aiola, a researcher at the Flatiron Institute's Center for Computational Astrophysics in New York City. "It speaks to the fact that these difficult measurements are reliable."
Comment: Whether it started by a Big Bang or some other way, we have a good idea of its beginning age.
Cosmology: Milky Way North and South giant bubbles
by David Turell , Wednesday, January 06, 2021, 23:41 (1416 days ago) @ David Turell
These are gamma ray and x-ray bubbles:
https://www.quantamagazine.org/space-telescope-shows-galaxy-size-bubbles-over-the-milky...
"He published simulations in 1977 that produced digital clouds lining up with the spur, and ever since then he has told anyone who would listen that the spur actually hovers tens of thousands of light-years above the disk. He described it as an expanding shock wave from a galactic calamity dating back millions of years.
***
"Then in 2010, the Fermi space telescope caught the faint gamma-ray glow of two humungous lobes, each extending roughly 20,000 light-years from the galaxy’s center. They were too small to trace the North Polar Spur, but they otherwise looked just like the galactic-scale clouds of hot gas Sofue predicted. Astronomers began to wonder: If the galaxy had at least one pair of bubbles, perhaps the spur was part of a second set?
***
"The new images have further cemented the change of opinion. They came from eROSITA, an orbiting X-ray telescope that launched in 2019 to track dark energy’s effect on galaxy clusters. The eROSITA team released a preliminary map in June, the fruit of the telescope’s first six months of observations.
"The map traces X-ray bubbles that stand an estimated 45,000 light-years tall, engulfing the gamma-ray Fermi bubbles. Their X-rays shine from gas that measures 3 million to 4 million degrees Kelvin as it expands outward at 300 to 400 kilometers per second. And not only does the northern bubble align perfectly with the spur, its mirror image is obvious as well, just as Sofue predicted. “I was particularly happy to see the southern bubble clearly exhibited, so similar to my simulation,” he said.
***
"But the meaning of eROSITA’s mushroom clouds is clear: Something went bang in the center of the Milky Way around 15 million to 20 million years ago, around the same time hyenas and weasels were emerging on Earth.
“I think now [the debate] is done, more or less,” said Predehl, who spent 25 years developing eROSITA.
"What exploded? Based on the energy required to make the clouds so big and so hot, there are two plausible sources.
***
"The ... culprit is the supermassive black hole that sits at the galaxy’s heart. The 4-million-solar-mass leviathan is relatively quiet today. But if a large cloud of gas once strayed too close, the black hole could have switched on like a spotlight. While feasting on the hapless passerby, the black hole would have gobbled down half the cloud while energy from the other half sprayed out above and below the disk, inflating the X-ray bubbles and perhaps the Fermi bubbles too (although the two pairs could also represent separate episodes of activity, Predehl noted).
"Astronomers have long observed other galaxies that shoot out jets above and below their disks, and they’ve wondered what makes the central supermassive black holes in those galaxies churn so much more violently than ours does. The Fermi bubbles, and now the eROSITA bubbles, suggest that the main difference may simply be the passage of time."
Comment: It all gets complexer and complexer and God has not explained why all the weirdness. But is always tums out the weird is necessary, and makes us agree God knows what He is doing and how everything we see must be necessarily designed for creation.
Cosmology: Milky Way has a churning dangerous core
by David Turell , Sunday, February 28, 2021, 04:23 (1364 days ago) @ David Turell
The giant core is filled with activity:
https://www.universetoday.com/150287/the-core-of-the-milky-way-is-an-extreme-place/
"One of the violent places that astronomers love to study is the center of our Milky Way galaxy.
***
"The area of the galaxy they studied, known as the “central molecular zone” (CMZ) spans the 1600 light years closest to the supermassive black hole at the center of the Milky Way. That is approximately 16 times closer to the galactic center than our own sun is. Almost everything about this part of the galaxy is more “intense” than the further out reaches. The molecular gas clouds that comprise it have higher magnetic fields, radiation, and even pressures and temperatures.
***
"These types of extreme conditions are ideal places for stars to form, though there are several evolutionary steps the molecular gas clouds must go through before ending up as a ball of nuclear fusion. First, the molecular gas must form into “clumps” between 1 and 10 light years in diameter. If enough material accretes into a given clump, it can move on to the next stage, where it forms what is known as a “core”. Cores are about 10% the size of a clump, but contain all the same material, and therefore have much higher temperature and pressure than their predecessors. Cores then occasionally give birth to individual stars.
"This process is extremely slow and can take millions of years to transition from one state to another. To truly grasp how these transitions might happen, it is best to study as many distinct clumps as possible to watch discrete points in the evolution of the systems. Foreground and background emissions (i.e. noise) have so far made it extremely difficult to assess the prevalence of clumps or cores anywhere near the center of the galaxy, however.
"What was needed to tease the signal from the noise was a significant amount of time on a very powerful telescope. That is just what the research team received by obtaining 550 hours of observing time on the Submillimeter Array (SMA). With their data in hand, the team scoured it to find 285 new stand-alone cores that could eventually begin to form a star. Additionally, there are 531 other potential core candidates in the data, but their presence was not conclusive enough to include them in the total count without further confirmation first.
"Confirmation of another interesting observation was also hidden in the data – that cores form stars as a much lower rate than would be expected via modeling. In fact, the data from the SMA point toward star formation being as common elsewhere in the galaxy as it is in the cores at the violent center of the galaxy. That puzzles astronomers, as the higher pressures and temperatures in the center of the galaxy should be more conductive to the formation of stellar objects."
Comment: So we have a giant galaxy which is presenting puzzles when compared to theories based on other galaxies. Are we just different or special? Noted again, our Earth is way far away from all that dangerous activity. By design I would think, to protect life.
Cosmology: Milky Way still growing

Absorbing tiny satellite galaxies:
http://www.sci-news.com/astronomy/pontus-galaxy-10564.html?utm_source=feedburner&ut...
"Our Milky Way Galaxy began forming around 12 billion years ago. Since then, it has been growing in both mass and size through a sequence of mergers with smaller galaxies.
Perhaps most exciting is that this process has not quite finished, and by using Gaia data, astronomers can see it taking place.
***
“'If this process goes slowly, the stars from the merging galaxy will form a vast stellar stream that can be easily distinguished in the halo.”
“'If the process goes quickly, the merging galaxy’s stars will be more scattered throughout the halo and no clear signature will be visible.”

Perhaps most exciting is that this process has not quite finished, and by using Gaia data, astronomers can see it taking place.

Cosmology: Milky Way's violent history
by David Turell , Thursday, September 28, 2023, 23:26 (421 days ago) @ David Turell
Adding new parts:
https://www.quantamagazine.org/in-the-milky-ways-stars-a-history-of-violence-20230928/
"A supermassive black hole churns at its center, surrounded by the “bulge,” a knot of stars containing some of the galaxy’s oldest stellar denizens. Next comes the “thin disk” — the structure we can see — where most of the Milky Way’s stars, including the sun, are partitioned into gargantuan spiraling arms. The thin disk is encased in a wider “thick disk,” which contains older stars that are more spread out. Finally, a mostly spherical halo surrounds these structures; it is mostly made of dark matter, but also contains stars and diffuse hot gas.
***
"Everything changed in 2016, when the first data from the European Space Agency’s Gaia satellite came back to Earth. Gaia precisely measures the paths of millions of stars throughout the galaxy, allowing astronomers to learn where those stars are located, how they move through space, and how fast they are going. With Gaia, astronomers could paint a sharper picture of the Milky Way — one that revealed many surprises.
"The bulge is not spherical but peanut-shaped, and it’s part of a larger bar spanning the middle of our galaxy. The galaxy itself is warped like the brim of a beat-up cowboy hat. The thick disk is also flared, growing thicker toward its edges, and it may have formed before the halo. Astronomers aren’t even sure how many spiral arms the galaxy really has.
***
"In the intervening century, astronomers have calculated that the Milky Way’s bulge is about 12,000 light-years across, that the disk spans 120,000 light-years, and that the halo of dark matter and ancient star clusters extends hundreds of thousands of light-years in every direction.
"A recent observation found that some halo stars are scattered as far as 1 million light-years away — halfway to Andromeda — which suggests that the halo, and therefore the galaxy, is not quite an island universe unto itself.
***
"In work published on September 14, Han and his team also showed that the dark matter halo might be tilted by about 25 degrees, causing the entire galaxy to look warped.
"And while that might seem weird enough, the tilt itself may be evidence of the Milky Way’s violent past.
***
"The first hints of violence came when astronomers peering through the storied 200-inch telescope at Palomar Observatory (which Hubble was the first to use) found evidence in 1992 that the Milky Way was ripping apart some of the globular clusters in its halo. The Sloan Digital Sky Survey confirmed that observation, and radio telescopes later found that the galaxy was also inhaling streams of nearby gas.
***
"As astronomers pored over the detailed motions and positions of about a billion stars, signs of a major disturbance in the galaxy emerged — they saw galactic wreckage in the halo. There, some stars orbit at extreme angles and have different compositions than others, suggesting that they originated somewhere else.
"Astronomers took these oddball stars as evidence of a titanic collision between the Milky Way and another galaxy. The merger, which probably happened between 8 billion and 11 billion years ago, would have catastrophically disrupted the young Milky Way, ripped the other galaxy to shreds, and sparked a firestorm of new star formation.
"The colliding galaxy’s remains are now called Gaia-Sausage-Enceladus, a result of two teams independently discovering the remnants of the merger.
***
"When Xiang and Rix used those clues to infer the migration histories of a quarter of a million subgiant stars, they found that the thick disk formed earlier than expected in galaxy formation theories — 13 billion years ago, barely an eye-blink after the Big Bang.
***
"The evidence for Gaia-Sausage-Enceladus continues to pile up. But what astronomers still don’t understand is why things have been calm ever since. The Milky Way’s chemical history and structural history seem atypical, Lu said.
"Andromeda, for instance, has a much more violent history than the Milky Way. It would be odd for our galaxy to be left alone so long, considering other galaxies’ histories and the prevailing cosmological model that says galaxies grow by smashing into each other, Wyse said. “The merging history is unusual, and the assembly history. Whether we are actually unusual in the universe … I would say is still an open question,” she said.
***
"Here, around one particular star on the Local Arm, eight planets formed around the sun — four rocky and four gaseous. But other arms may be different. Those environments might produce different populations of stars and planets in the same way that specialized flora and fauna evolve on continents with distinct biospheres.
“'Maybe life can only arise in a really quiet galaxy. Maybe life can only arise around a really quiet star,” said Jessie Christiansen, an astronomer at the California Institute of Technology who studies galactic conditions and their effects on planet-building." (my bold)
Comment: we are here on Earth going 'round a quiet star. In a very special galaxy. Serendipity, contingency or design? Only one cause must exist.

News study finds evidence of flowing water:
https://phys.org/news/2021-07-earth-orbit-enabled-emergence-complex.html
"Scientists at the University of Southampton have discovered that changes in Earth's orbit may have allowed complex life to emerge and thrive during the most hostile climate episode the planet has ever experienced.
"The researchers—working with colleagues...studied a succession of rocks laid down when most of Earth's surface was covered in ice during a severe glaciation, dubbed 'Snowball Earth', that lasted over 50 million years.
***
"The research team ventured into the South Australian outback where they targeted kilometre-thick units of glacial rocks formed about 700 million years ago. At this time, Australia was located closer to the equator, known today for its tropical climates. The rocks they studied, however, show unequivocal evidence that ice sheets extended as far as the equator at this time, providing compelling evidence that Earth was completely covered in an icy shell.
"The team focused their attention on "Banded Iron Formations", sedimentary rocks consisting of alternating layers of iron-rich and silica-rich material. These rocks were deposited in the ice-covered ocean near colossal ice sheets.
***
'The team's results help explain the enigmatic presence of sedimentary rocks of this age that show evidence for flowing water at Earth's surface when this water should have been locked up in ice sheets. Dr. Gernon states: "This observation is important, because complex multicellular life is now known to have originated during this period of climate crisis, but previously we could not explain why".
"'Our study points to the existence of ice-free 'oases' in the snowball ocean that provided a sanctuary for animal life to survive arguably the most extreme climate event in Earth history", Dr. Gernon concluded."

Another study in China:
https://www.sciencedaily.com/releases/2021/08/210827121450.htm
"Around 650 million years ago, the Earth entered into the Marinoan glaciation that saw the entire planet freeze. The 'Snowball Earth' impeded the evolution of life. But as it warmed, biotic life began to flourish. A research team has now analyzed rock samples from China to tell us more about this transition.
"A research team from Tohoku University has unveiled more about the evolutionary process of the Marinoan-Ediacaran transition. Using biomarker evidence, they revealed possible photosynthetic activity during the Marinoan glaciation. This was followed by photosynthetic organisms and bacteria entering a period of low productivity. However, as eukaryotes expanded during the early Ediacaran period, they blossomed.
***
"Bacteria and eukaryote biomarkers demonstrate that bacteria dominated before the glaciation, whereas steranes/hopanes ratios illustrate that eukaryotes dominated just before it. However, the relationship between the biosphere changes and the Marinoan glaciation is unclear.
***
"Kaiho believes we are one step closer to understanding the evolutionary process that occurred before and after Snowball Earth. "The environmental stress of closed ocean environments for the atmosphere followed by high temperatures around 60°C may have produced more complex animals in the aftermath." Their findings show that bacterial recovery preceded eukaryotes' domination."
Comment: The Ediacaran diversity that appeared is very simple compared to the later Cambrian Explosion animals. This shows part of the evolutionary process that finally created our current biosphere.

More snnowball Earth information:
https://www.smithsonianmag.com/science-nature/how-animals-may-have-conquered-snowball-e...
"Planet Earth used to be something like a cross between a deep freeze and a car crusher. During vast stretches of the planet’s history, everything from pole to pole was squashed beneath a blanket of ice a kilometer or more thick. Scientists call this snowball Earth.
"Some early animals managed to endure this frigid era from roughly 720 to 580 million years ago, but they had their work cut out for them. Despite their valiant successes, the repeated expansion and contraction of giant ice sheets pulverized the hardy extremophiles’ remains leaving almost no trace of them in the fossil record and scientists with little to no idea of how they managed to survive.
“'It’s basically like having a giant bulldozer,” says Huw Griffiths of the British Antarctic Survey. “The next glacial expansion would have just erased all that and turned it into mush, basically.”
"Despite the lack of direct evidence thanks to all that glacial churning, Griffiths argues it is reasonable to propose that a diverse range of animal life inhabited snowball Earth. He suggests that this flourishing would have pre-dated the so-called Cambrian explosion, a period around 540 million years ago when a great and unprecedented diversity of animal life emerged on Earth. “It’s not a huge leap of imagination that there were much smaller, simpler things that existed before that,” Griffiths says.
***
"The team considered three different frozen periods. The first was the Sturtian snowball Earth, which began about 720 million years ago. It lasted for up to 60 million years. This is a mind-blowingly long time—it’s nearly as long as the period between the end of the dinosaur era and today. Then came the Marinoan snowball Earth, which started 650 million years ago and lasted a mere 15 million years. It was eventually followed by the Gaskiers glaciation around 580 million years ago. This third glaciation was shorter still and is often called a slushball rather than a snowball Earth because the ice coverage was likely not as extensive.
"Though the ice smushed most of the fossils from these periods, scientists have found a handful of remnants. These rare fossils portray the weird animals that existed around the time of the Gaskiers glaciation. Among these ancient slushball-Earth dwellers were the frondomorphs—organisms that looked a bit like fern leaves. Frondomorphs lived fixed to the seafloor beneath the ice and possibly absorbed nutrients from the water as it flowed around them.
"Short on direct evidence, Griffiths and his colleagues instead argue that the survival strategies of animals during the great freezes of the past are likely echoed by the life that dwells in the most similar environment on Earth today—Antarctica.
***
"One of the challenges that inhabitants of a snowball Earth faced was the possible lack of oxygen, both because the oxygen levels in the air were low and because there was limited mixing from the atmosphere into the water. But oxygenated meltwater high in the water column might have supported animals that depended on it. Some denizens that live on the Antarctic seafloor today, such as certain species of feather star, solve this problem by relying on water currents to bring a steady flow of oxygen and nutrients from the small areas of open water at the surface to deep below the ice shelves. There’s no reason to think this didn’t happen during the Gaskiers slushball Earth period, too.
***
"Andrew Stewart, assistant curator at the Museum of New Zealand Te Papa Tongarewa who also wasn’t involved in the paper, has studied countless species from harsh Antarctic environments. Many of these organisms cope in incredibly dark, cold, or chemically toxic places. For Stewart, Antarctic extremophiles are a reminder of how robust life on Earth really is—and perhaps always has been.
“'It’s just the most amazing place,” he says. “You go, No, bollocks, nothing can survive there! Well, actually it can.'”
Comment: of course, life survived these snowball periods. And the question of low oxygen is answered in previous entries as being adequate. A good research paper has as full review of the literature; this one obviously did not find my entries. The major point, however, is that it reenforces my view that God doesn't control every nuance of climate change but can respond with DNA alteration in new species. God is in total control of evolutionary destiny!!! A totally different an analysis than dhw's contrary distortions of my theory.

A new review and study:
https://www.sciencealert.com/snowball-earth-may-not-have-been-an-endless-frozen-wastela...
"Long before complex life crawled from the oceans to make itself at home on dry land, Earth endured an ice age like no other. On two separate occasions, fingers of ice stretched far from the poles, turning the planet into a frozen wasteland.
"Just how far glaciers reached has been a matter of debate. Some contend the runaway deep freeze extended across all latitudes, completely coating Earth in a thick coat of ice as far as the equator.
"Others argue equatorial latitudes may have been relatively ice-free. Evidence buried in the fossil record also suggests there might have been patches of exposed ocean, enough for oxygen and light to permeate the waters and allow complex life to flourish.
"In that vein, a new study by researchers from China and the UK is the latest to suggest 'Snowball Earth' wasn't completely covered in ice – and might have even exhibited habitable open-ocean conditions far away from the equator.
"Just what caused Earth to suddenly dip into an extended cold snap around 700 million years ago isn't all that clear. A drop in sunlight perhaps, or a loss of greenhouse gases, followed by a feedback of ice reflecting heat, creating yet more ice.
***
"While this may have helped kick-start a biodiversity explosion, times would have been tough for complex life trying to survive in cold waters cut off from the atmosphere in the midst of the extreme ice age. Starved of oxygen, life should, in theory, have been dominated by simple anaerobes and deep-dwelling chemotrophs.
"Only that isn't what the fossil record shows. Black shales buried in the Nantuo Formation of South China preserve traces of sediments shed by the Marinoan glaciers. Within them are macroscopic traces of surprisingly complex organisms, interpreted as a kind of algae.
"Being photosynthetic means a reliance on sunlight, meaning Snowball Earth might have been speckled with patches of ice-free ocean where life could stare up at the sky and soak up the rays.
"As far as evidence of exposed ocean during the Marinoan glaciation goes, questionable fossils of macroscopic algae leave plenty of room for debate.
"By analyzing the chemistry of the Nantuo Formation shale, the team behind this latest investigation hoped to uncover additional evidence that would help determine whether areas of the surface remained ice-free during this important period in Earth's history.
"Examining the nature of the material's iron content, for example, provided data on redox reactions that described levels of oxygen at the interface between sediment and the water above. By studying the mix of nitrogen isotopes, the team could get a better sense of the aerobic nitrogen cycle occurring near the water's surface.
"Putting the results into context provided by numerous other studies, it appears at least some of the planet's surface was ice-clear towards the close of the Marinoan, providing a warm oasis for photosynthesizing organisms.
"Importantly, based on the location of the fossil beds in South China more than half a billion years ago, these ice-free islands of open water would have appeared at mid-latitudes, far from the equator.
"Though it's possible meltwater ponds in the glaciers could have provided similar access to oxygen and light, the researchers argue it's unlikely such lakes would have had sufficient organic matter to keep carbon and nitrogen cycles churning.
"Being more of a 'slushball' than a completely frozen ball of ice would mean Earth's more complex life forms had refuges from the inhospitable darkness, allowing them to rebound more quickly once the planet warmed."
i
Comment: there were simple forms that survived. We are here after all that adversity. This supports my theory God did not control environmental events. An all-powerful God allowed this is happen, but it didn't get in His way.
Cosmology: snowball Earth possible cause

New research on an old theory:
https://www.science.org/content/article/massive-lava-outburst-may-have-led-snowball-ear...
"About 717 million years ago, a climate catastrophe struck the planet, as temperatures plunged and glaciers enveloped the globe. The cause of this “Snowball Earth” episode has been mysterious, but it took place around the same time as a massive outburst of volcanism. Many researchers thought there might be a connection. But the timing was uncertain.
"Now, more precise dates, reported last month in Earth and Planetary Science Letters (EPSL) and in November 2022 in Science Advances, show the eruptions preceded the Snowball Earth event by 1 million to 2 million years. The lag points to a particular way the fire could have triggered the ice: through a chemical alteration of the fresh volcanic rocks known as weathering, which sucks carbon dioxide (CO2) from the atmosphere, turning down the planetary thermostat. The studies highlight the power of weathering as a key driver behind shifts in Earth’s climate, and how components of the planet as disparate as rocks and the atmosphere are inextricably linked, says EPSL study co-author Galen Halverson, a sedimentary geologist at McGill University. “Nothing can be understood in isolation.”
"Geoscientists debating the cause of the so-called Sturtian glaciation, which lasted 57 million years, have pointed to a number of possibilities—meteorite strikes, biologic activity, shifts in Earth’s orbit, and more. But recent studies have zeroed in on one of the largest volcanic outbursts ever, preserved today across northern Canada in what’s called the Franklin large igneous province (LIP). The eruptions spewed lava across an area at least the size of Argentina—and perhaps bigger than China.
"Volcanism can trigger cooling in two main ways. In one, eruptions release sulfur-rich gases, which form aerosols that block sunlight and cool the planet. A section of the Franklin lava likely even burst through rocks full of sulfur-rich minerals that could have supercharged the plumes. The other mechanism is weathering. Lava rocks are particularly susceptible to the reactions, in which CO2 in rainwater reacts with the rocks, ultimately forming minerals that precipitate in the ocean.
***
"By measuring the ratios of trace amounts of uranium and lead trapped in tiny crystals of the mineral zircon—and knowing how fast uranium decays to lead—the teams discovered that the Franklin LIP formed in just 2 million years or so, much faster than most previous estimates. And the primary pulse of volcanism happened 1 million to 2 million years before Snowball Earth, which has been dated through analysis of rocks scoured up by glaciers and eventually deposited in the ocean.
"That’s exactly the sort of time frame required for weathering to cause the cooling. “They’re just stunning the extent to which [the dates] all line up,” Halverson says. Additional analysis by Pu and her colleagues suggest the Franklin LIP formed a broad volcanic highland that would have been battered by wind and water, speeding up the weathering.
"Pu says other factors may have dialed up the weathering enough to cause a Snowball Earth event. For starters, all of Earth’s landmasses at the time were located near the equator, where temperatures were warm and rain frequently pelted the surface. The floods of lava also emerged during the breakup of the Rodinia supercontinent, which exposed fresh rocky surfaces to weathering and may have already begun to cool the global climate. And Gumsley says other large eruptions probably took place at this time in Siberia, China, Africa, and Antarctica, adding to the overall weathering effect.
"Case closed? Not for Harvard University geologist emeritus Paul Hoffman, a coauthor on the Science Advances study who led much of the early work on Snowball Earth. Even if the timing of the Franklin LIP has improved, that of the global glaciation remains slightly uncertain, he says. Forming the ice-scoured rock that marks the start of the episode requires the flow of thick ice at sea level, a process that may not have started until several hundred thousand years after the oceans froze over.
"Other Snowball periods remain mysterious. Some 650 million years ago, not long after the Sturtian glaciation, the planet plunged into another deep freeze—but no volcanic outburst preceded it, notes Linda Sohl, a paleoclimatologist at Columbia University who was not part of the study teams. Still, Halverson says weathering may have been a key factor then, too, because all the scouring by glaciers during the earlier Snowball would have exposed fresh rock.
"For the Sturtian glaciation at least, the case for a weathering trigger has grown, Sohl says. “In the very least, a revisit with weathering models seems in order,” she says. “The snowball glaciations are such fascinating events that are going to keep all of us quite busy for years to come.'”

Low CO2:
https://www.sciencedaily.com/releases/2024/02/240207194410.htm
"Inspired during field work in South Australia's Flinders Ranges, geoscientists have proposed that all-time low volcanic carbon dioxide emissions triggered a 57-million-year-long global 'Sturtian' ice age.
***
"'We now think we have cracked the mystery: historically low volcanic carbon dioxide emissions, aided by weathering of a large pile of volcanic rocks in what is now Canada; a process that absorbs atmospheric carbon dioxide."
***
"The extended ice age, also called the Sturtian glaciation after the 19th century European colonial explorer of central Australia, Charles Sturt, stretched from 717 to 660 million years ago, a period well before the dinosaurs and complex plant life on land existed.
"Dr Dutkiewicz said: "Various causes have been proposed for the trigger and the end of this extreme ice age, but the most mysterious aspect is why it lasted for 57 million years -- a time span hard for us humans to imagine."
"The team went back to a plate tectonic model that shows the evolution of continents and ocean basins at a time after the breakup of the ancient supercontinent Rodina.
***
"They soon realised that the start of the Sturtian ice age precisely correlates with an all-time low in volcanic CO2 emissions.
"In addition, the CO2 outflux remained relatively low for the entire duration of the ice age.
"Dr Dutkiewicz said: "At this time, there were no multicellular animals or land plants on Earth. The greenhouse gas concentration of the atmosphere was almost entirely dictated by CO2 outgassing from volcanoes and by silicate rock weathering processes, which consume CO2."
"Co-author Professor Dietmar Müller from the University of Sydney said: "Geology ruled climate at this time. We think the Sturtian ice age kicked in due to a double whammy: a plate tectonic reorganisation brought volcanic degassing to a minimum, while simultaneously a continental volcanic province in Canada started eroding away, consuming atmospheric CO2.
"'The result was that atmospheric CO2 fell to a level where glaciation kicks in -- which we estimate to be below 200 parts per million, less than half today's level."
***
"Dr Dutkiewicz said: "Whatever the future holds, it is important to note that geological climate change, of the type studied here, happens extremely slowly. According to NASA, human-induced climate change is happening at a pace 10 times faster than we have seen before.'"
Comment: So, in view of the fact that CO2 is an important friend who keeps us warm, CO2 is not an enemy. Obviously volcanic outgassing plays a major role in CO2 levels along with the human input. We certainly do not want another glacial period. And we must understand all the simulations of future climate temperatures are extremely inaccurate. Is current alarmism necessary?
Cosmology: snowball Earth from methane drop
by David Turell , Saturday, April 06, 2024, 17:27 (230 days ago) @ David Turell
Less methane, more cold with less greenhouse gas:
https://bigthink.com/starts-with-a-bang/oxygen-killed-life-on-earth/?utm_source=interna...
"The cyanobacteria, experiencing the massive success of having an unlimited nutrient source wherever sunlight strikes the surface of the ocean, evolved into microbial mats in short order. Once they began producing oxygen, the early presence of that molecule systematically removed the early methane from Earth’s atmosphere, as oxygen reacts with methane to produce carbon dioxide and water. The loss of that early methane — a fabulously efficient heat-trapping molecule — greatly decreased the greenhouse effect from Earth’s early atmosphere: causing global temperatures to begin to drop.
***
"The Sun’s energy output, like that of all stars, was much lower in the early stages of its life, and so the large abundance of atmospheric methane was the only thing keeping Earth warm enough to have liquid water on its surface. With the oxygen destroying that powerful greenhouse gas, the planet couldn’t retain its heat nearly as well. This spawned the greatest ice age in history, leading to Snowball Earth conditions that lasted for approximately 300 million years.
"The geological evidence is overwhelming for incredibly cold conditions covering the entire planet at this time. Glacial deposits throughout northern North America (but also found as far away as Australia) display multiple sedimentary layers that show evidence for this frozen period persisting for long periods of time, spanning ages that correspond to being between 2.5 and 2.0 billion years ago. Evidence for past glaciation events, where glacial deposits must have been made even at then-tropical (i.e., equatorial) latitudes, has been very strong for more than half a century.
***
"Once you cool the Earth and remove its heat-trapping atmospheric layers, further cooling appears to be a runaway process. If ice sheets advance far enough down below the polar regions, it increases the total reflectivity of the planet, which translates into less solar energy being absorbed by the Earth overall. The further cooling leads to the formation of even more ice, which can eventually cover the entire surface of the planet — continents and oceans both included — in a global layer of ice. That’s what a “Snowball Earth” set of conditions looks like.
***
"It was geology, however, and not biology, that eventually led to the end of these Snowball Earth conditions. Even as the planet remained frozen, plate tectonics continued, as continental drift, seafloor spreading, earthquakes, and volcanic eruptions all persisted. In particular, volcanoes continued to erupt beneath the ice, spewing those volcanic gases upward, where they would lead to cracks and fissures in the ice sheets. As volcanoes add copious amounts of carbon dioxide to the atmosphere, they began increasing the strength of the planet’s greenhouse effect once again, while the simultaneous production of ash began to decrease the reflectivity of Earth. Eventually, after approximately 300 million years, our planet finally broke out of this glaciation era.
***
"Although much remains to be learned about the evolutionary process during these Snowball Earth conditions, it’s arguable that human-like life would never have arisen if oxygen had never destroyed our methane-rich atmosphere and given life the opportunity to evolve in this spectacular, unique direction.
"The period of time corresponding to 2.5 billion years ago in Earth’s natural history may yet represent the greatest mass extinction our planet has ever faced. Even at this primitive stage, however, life remained ubiquitous and resilient, with the destruction of the pre-existing dominant species enabling other, new organisms to evolve and rise to prominence, filling those now-vacant ecological niches. The Great Oxygenation Event was a transformative occurrence in Earth’s history, and may have paved the way for complex and differentiated life on our world. Without it, life may never have achieved the diversity it now boasts today, and the tree of life may not have been capable of giving rise to intelligent, advanced organisms like us."
Comment: this description of the history and causes of snowball Earth presents us with an amazing set of improbable contingencies which allowed us to appear. The logical explanation is a designer God.
Cosmology: snowball Earth's last disappearance

From studies of specialized rock:
https://www.sciencedaily.com/releases/2024/09/240918165736.htm
"Some of the most dramatic climatic events in our planet's history are "Snowball Earth" events that happened hundreds of millions of years ago, when almost the entire planet was encased in ice up to 0.6 miles (1 kilometer) thick.
"These "Snowball Earth" events have happened only a handful of times and do not occur on regular cycles. Each lasts for millions of years or tens of millions of years and is followed by dramatic warming, but the details of these transitions are poorly understood.
***
"The study recently published in Nature Communications focuses on ancient rocks known as "cap carbonates," thought to have formed as the glacial ice thawed. These rocks preserve clues to Earth's atmosphere and oceans about 640 million years ago, far earlier than what ice cores or tree rings can record.
"'Cap carbonates contain information about key properties of Earth's atmosphere and ocean, such as changing levels of carbon dioxide in the air, or the acidity of the ocean," said lead author Trent Thomas, a UW doctoral student in Earth and space sciences. "Our theory now shows how these properties changed during and after Snowball Earth."
"Cap carbonates are layered limestone or dolomite rocks that have a distinct chemical makeup and today are found in over 50 global locations, including Death Valley, Namibia, Siberia, Ireland and Australia. These rocks are thought to have formed as the Earth-encircling ice sheets melted, causing dramatic changes in atmospheric and ocean chemistry and depositing this unique type of sediment onto the ocean floor.
"They are called "caps" because they are the caps above glacial deposits left after Snowball Earth, and "carbonates" because both limestone and dolomite are carbon-containing rocks. Understanding their formation helps explain the carbon cycle during periods of dramatic climate change. The new study, which models the environmental changes, also provides hints about the evolution of life on Earth and why more complex lifeforms followed the last Snowball Earth.
"'Life on Earth was simple -- in the form of microbes, algae or other tiny aquatic organisms -- for over 2 billion years leading up to Snowball Earth," said senior author David Catling, a UW professor of Earth and space sciences. "In fact, the billion years leading up to Snowball Earth are called the 'boring billion' because so little happened. Then two Snowball Earth events occurred. And soon after, animals appear in the fossil record."

"Eventually, carbon dioxide built up in the atmosphere to the point where it trapped enough solar energy to raise global temperatures and melt the ice. This let rainfall reach the Earth, and let freshwater flow into the ocean to join a layer of glacial meltwater that floated over the denser, salty ocean water. This layered ocean slowed down ocean circulation. Later, ocean churning picked up, and mixing between the atmosphere, upper ocean, and deep ocean resumed.
"'We predict important changes in the environment as Earth recovered from the Snowball period, some of which affected the temperature, acidity and circulation of the ocean. Now that we know these changes, we can more confidently figure out how they affected Earth's life," Thomas said."
Comment: the disappearance of snowball Earth set the stage for the first animals to appear perhaps by setting up a nutrient supply. Ediacaran and Cambrian animals followed
Cosmology: the mysterious neutrino

It can be three things at once:

"Neutrinos are fundamental to the construction of the Universe. They are tremendously abundant, outnumbering atoms by about a billion to one. They modulate the reactions that cause massive stars to explode as supernovas. Their properties provide clues about the laws governing particle physics. And yet neutrinos are among the most enigmatic particles, largely due to their reticent nature: they have no electric charge and practically no mass, so they interact only extremely weakly with ordinary matter. Some 65 billion of them stream through every square centimetre of your body – an area the size of a thumbnail – every second, without your ever noticing them.
"Through elaborate sleuthing, physicists have identified three distinct types of neutrinos, which differ in their subtle interactions with other particles. Stranger still, the neutrinos can ‘oscillate’ between types, shedding one identity and adopting another as they travel through space. That discovery led to a significant expansion of the standard theory of how particles behave. Now neutrinos and their subtle oscillations have helped physicists prove an even deeper mystery of matter.

"The core of the Sun is a massive nuclear reactor, and theories of nuclear physics yielded a highly precise prediction of the neutrino flux that the Sun should produce. However, more sensitive follow-up experiments to the original Reines-Cowan test had found only about one third the expected number of solar neutrinos. During the early stirrings of US-USSR détente in the late 1960s, Pontecorvo was able to share his latest ideas directly with colleagues in the West. He now calculated that neutrinos should oscillate among three distinct flavours. If so, the solar neutrino detectors, which were only sensitive to one of the flavours, should register the readings of the neutrino flux that the experimentalists kept finding.
***
"The origin and nature of neutrino mass remains a major ongoing area of exploration. Physicists also continue to test whether only three flavours of neutrinos exist in nature. Any more than three would provide decisive evidence that the Standard Model of particle physics – a theory which has successfully described every experiment involving elementary particles for more than forty years – is incomplete.
***
"According to quantum theory, neutrinos’ flavour-changing ways are directly analogous to Schrödinger’s half-dead/half-alive cat, making neutrino oscillations a powerful way to explore the validity of superposition. My colleague Joe Formaggio realized that we could analyze how the mix of neutrino flavours changes as the particles travel, finally settling into a single flavour (equivalent to a definitive verdict of a ‘dead’ or ‘alive’ cat) when measured.
***
"Quantum effects like superposition are usually only manifest over incredibly short distances of tens or hundreds of nanometers, but our test demonstrated unmistakable quantum strangeness over a span of 735 kilometres. And that may be just the beginning. The world is awash in neutrinos that have traveled 150 million kilometres from the Sun, and cutting-edge experiments like the IceCube Neutrino Observatory at the South Pole can now detect primordial neutrinos that have been traveling through space for billions of years, ever since the Big Bang. Perhaps neutrinos like these can also be coaxed to reveal tell-tale signs of quantum superposition. Then we could test this central feature of quantum theory across the vastness of cosmic distances.
"In the meantime, by puzzling through the strange dance of oscillating neutrinos, my colleagues and I have found that, for all of the apparent fairytale strangeness of quantum mechanics, its predictions hold up at human scales. Perhaps it is fitting that the neutrinos’ journey from Fermilab to the Soudan mine is about the same distance that Pontecorvo himself traveled during his storied lifetime, bounding from Rome to Paris or sneaking from Helsinki to Moscow. Across distances like these, we can say with confidence that we really do live in a world of strange superpositions."
Comment: More evidence that the basis of the universe is quantum mechanics. What is more amazing is that big brained H. sapiens could predict the neutrino and then start to understand what they mean to the standard model. It takes the big brain, which started out 300,000 years ago not knowing what it did not know. Size first, obviously.

What is more interesting to me is that research into Quantum Physics implies that these particles alter their 'reality' based on OBSERVATION. The ACT of OBSERVING them changes the way they behave. We have all heard that. It is part the logic behind Schrodinger's Cat, Quantum Entanglement, and Superposition. What I find interesting is that no one that I have heard of ever asked the most interesting question of all:
If quantum particles respond to observation, and they are older than any known existing consciousness, whose conscious observation were they responding to during the formation of our universe? What 'LAW' governs that they respond to observation, and why would that law even exist in nature if there were nothing to observe them? No other fundamental law requires pre-existing consciousness to have meaning at time of implementation. i.e. At T0, all other natural laws that we know of (more or less) make sense in and of themselves, without the need for any external validation. This effect ONLY makes sense in the presence of pre-existing consciousness, unlike all other 'natural laws'.

What is the purpose of living? How about, 'to reduce needless suffering. It seems to me to be a worthy purpose.

Your point makes mine that quantum mechanics strongly suggest the existence of a universal consciousness (God).
