> dhw: Which of you should I believe? David says photons are pure energy. GK says they don't know what photons are. He says waving is important ... so is there a link between waving and pure energy? GK says quantum mech is based on "probability". Probabilities seem to change with every new discovery ... see below.-GK and I are the same. With appologies to him, I don't think English is his first language, so he expresses himself slight askew. A photon is a wave and a particle, and really a smudge in afield. (Strassler)-> 
> dhw: I'm not going to pretend that I understand all this, but it might help me if you could tell me what part of the process constitutes "pure energy". -The history of the universe is what I keep directing you toward. The hot bb was a plasma of energy which as it cooled formed the particles that have been discovered so far. It is these energy particles that formed atoms, which formed elements which made the matter we know.
> 
> dhw:You describe this unproven theory as "the whole outline of our universe's history". If the scientists themselves have such reservations, shouldn't we? -Of course it is all theoretical history, but the theory led to the atom bomb.-> 
> dhw:But can atomic energy be produced without matter?-In a way, yes, but actually we are working the universe's history backward from the radioaactive matter we have to work with. Ordinary matter cannot be exploded or put in nuclear electric plants or submarines.-
> dhw; These scientists, whose article you have recommended, favour the multiverse theory, and the use of the present perfect certainly does not preclude universes in the past. But there cannot be a past without time. Ergo, we cannot state with any certainty that time began with the origin of OUR universe.-I'm using the article to educate you. If something existed without change before our universe appeared, there was no sequesnce of events to produce the illusion of time.

> GATEKEEPER: I could write a book on this stuff relating to "god", basically the book would be title "it is ok to believe using real science".

> dhw:David is too modest to mention that he has already beaten you to it. He has just published a book called The Atheist Delusion ... Science IS Finding God. I recommend it, even to my fellow agnostics and to those atheists whose minds are not yet fully closed.-Thank you.
