There is no problem conving David or myself of this, but both Tony and dhw have expressed differing degrees of skepticism. (scepticism for our british friend, but then how do we pronounce "scepter?")-Quote:-" Light from objects so distant has been stretched toward longer wavelengths as it travels across the expanding universe, and astronomers and cosmologists use the degree of stretching, or redshift, as a measure of distance traveled. In the case of SXDF-NB1006-2, the redshift implies that the object existed nearly 13 billion years ago."- http://blogs.scientificamerican.com/observations/2012/06/07/astronomers-identify-very-d... the big bang never happened, then why does correcting for the rate of expansion allow us to find results such as this?

There are other models I have linked before, such as the electric universe model, that also account for these same type of result. More to the point, there are a lot of assumptions being made not only about what they are seeing, but about what those sightings really indicate. That is why the article is filled with phrases like 'seem to be', 'seem to indicate', 'implies', and other vagaries. -All of that being said, my biggest issue with the BBT is that it suffers from the same problem as evolution. It is being read as Fact instead of Theory. Even in scientific terms there is a difference between the two. Unfortunately, modern science often seem to confuse the two, and put on their blinders.-Is it wrong to hope that scientist would keep an open mind?

If the electric universe theory had been proposed at the same time as BBT, we might well have a reversed scenario. -I say this because of this quote from Paul Davies:- "In spite of its Velikovskian flavour, the Bally-Harrison electric universe unfortunately does not lead to any obviously important astrophysical consequences."-This means that yes, indeed, it can explain the same phenomenon as BBT, however, because it doesn't do a fundamental thing:-1. Explain everything BBT explains, plus a phenomenon that BBT doesn't explain.-It isn't a valid candidate (at this time) to replace BBT, spend Billions rewriting textbooks, and all the other difficult things we need to do when a major theory is overturned.-Here's criticism of the theory of unknown origin, but some learned insights:- http://neutrinodreaming.blogspot.com/2011/09/electric-universe-theory-debunked.html-(Ap... there are things I hadn't looked at when you originally posted the links. I'm less inclined to agree with Davies than I was moments ago.)- [EDIT]-I will tie this back to our discussion that science is model building. Science needs to document theories like this, but pragmatically, since the theory doesn't really do anything new, it doesn't need that much scrutiny. Science is about moving forward, and fixing mistakes as they're made. You might not like it, but its the way it was designed to work from the beginning.

Actually, that's classic textbook "how scientists are always supposed to talk." > -Yes, agreed. Vagaries are classic textbook science jargon. Of that there was never a doubt. The doubt comes when the vagaries become touted as fact to the public. That, as I have always maintained, is a crucial sticking point for me, and will continue to be so.- > > What I don't think you realize is that science works, by giving credit to the first theory out of the gate. If the electric universe theory had been proposed at the same time as BBT, we might well have a reversed scenario. > -Perhaps, but then you are admitting the failure of the scientific method. The scientific method does not work by giving credit to the first one out the gate, it gives credit to the one that a) explains the observations best, b) offers the most predictable, testable results, and c) has not yet been directly disproven.- > I say this because of this quote from Paul Davies: > > "In spite of its Velikovskian flavour, the Bally-Harrison electric universe unfortunately does not lead to any obviously important astrophysical consequences." > -First, I was mistaken about something. Plasma Cosmology is the spin off from the Electric Universe Theory, and the one I am more satisfied (though not completely). Most of the rebuttals too it are straw man arguments, such as:-"Standard Newtonian gravity can't explain the observed rotation speeds of galaxies. The right answer is that there is dark matter in those galaxies; we know this is the right answer because there is a whole lot of other evidence for dark matter. However, MOND was introduced as a way of modifying Newtonian gravity, rather than by introducing a new component to galaxies, to explain the flaw."-Sure, say your model is right and the other is wrong because you have theoretical evidence of a theoretical substance that can never be observed.-> > 1. Explain everything BBT explains, plus a phenomenon that BBT doesn't explain. > -A) It doesn't have to explain everything that the first theory does, and truth be told, no new theory ever will. Why? Because old theories like the BBT have had decades of research poured into them, and when the observations didn't fit the predictions the theory was shored up with adhoc non-sense that became the common parlance. A hypothesis MUST go through the vetting and iterative refinement process of the scientific method. How else are the kinks supposed to get worked out? And how is that supposed to happen when new theories are dismissed out of hand simply because they are new.- B) The theory DOES do some new things. Originally I linked a whole slew of predictions made by this model that were not able to be accounted for by the bbt. Some of these predictions have been tested, by NASA no less, and shown to be valid, where as the predictions made by the bbt of the same event failed. That is something new. That explains something the old theory doesn't. It also accounts for numerous planetary phenomena that are also likewise inexplicable under the bbt paradigm, and requires no imaginary substances to do it.- > > > [EDIT] > > I will tie this back to our discussion that science is model building. Science needs to document theories like this, but pragmatically, since the theory doesn't really do anything new, it doesn't need that much scrutiny. Science is about moving forward, and fixing mistakes as they're made. -Yes, fix mistakes. Not cover them up with froo froo mathematical models with no observational backing in the real world.

Yes, fix mistakes. Not cover them up with froo froo mathematical models with no observational backing in the real world.-All models are wrong, but some are useful. George EP Box.-That is one of the points of building models so that we can test them. Just think we would never do anything if we did not build models, mathematical or physical.-It's OK to be skeptical of froo froo models - but before discarding them what is your observational evidence that they don't fit?-We built the first aircraft (model or otherwise) to see if we could fly. If these froo froo models don't fit the existing observational data then no one is going to buy into them anyway.->Matt - how do we pronounce "scepter?" The same way we pronounce "sceptre"?

> > 1. Explain everything BBT explains, plus a phenomenon that BBT doesn't explain. > > > > A) It doesn't have to explain everything that the first theory does, -Yes it does. If you're going to wholesale replace a model with a new one, ALL of the old observations need to be explained with the new model. It's not enough to just say "we explain a couple things you can't."-Science is about utility, and BBT hasn't expensed its usefulness yet.-You're arguing like a String Theorist here. -If you want electric universe to "work," at least go as far as String Theorists have done and demonstrate how electric universe math accounts for all the other phenomenon explained by the BBT.-That link I posted tells you all you need to tie in.-Ball's in your court....-It's up to the new guy to make his case and build support for his theory. Not the guys who already did that for their own.

You are arguing that the BBT explains a bunch of stuff, and to a certain extent it does, but a lot of its 'explanatory power' comes from either ignoring known physics, or using unobservable phenomena as a place holder. How is that ok?-I am not even saying that everything about the BBT is wrong, and in fact not even the Plasma Cosmology model says that everything about the BBT is wrong. There are areas where it is wrong, though, and there are areas where its predictions flat out fail. Here are a few good articles with supporting links.-http://www.nowpublic.com/tech-biz/big-bang-vs-plasma-cosmology-competing-approaches-cosmos-In short, the recent literature on physics makes one nostalgic for anything as reasonable as a witch trial.-I am not even saying that the plasma model is correct, only that given the number of failed predictions, and the amount of froo froo framework being needed to prop up the existing model, isn't it time to consider that maybe, just maybe it is wrong?

As for discarding the BBT, the only anomaly at present is dark matter. (This is coming from a non-astrophysicist such as myself.)-Before moving to something as earth-shaking, It would be much simpler to abscond the cosmological principle, and state that dark matter can be explained by statistical anomolies.-(at work. will read those links when I get home.)

These are needed, though unobserved and unobservable, to explain away the places where predictions made by the BBT flat out fail.

Obviously, indirectly, lol, but that moved from hypothesis to accepted fact within the last 20 years.-Dark matter and dark energy however... -To my knowledge we've only "discovered" these in the last 10 or so. I still say that we can just abandon the cosmological principle and the problem of dark matter/energy disappears entirely.

I can now reveal the closely guarded secret that British orthography is the foundation stone of chaos theory. Or should that be khaos? MATT (quoting):" Light from objects so distant has been stretched toward longer wavelengths as it travels across the expanding universe, and astronomers and cosmologists use the degree of stretching, or redshift, as a measure of distance traveled.
