Title: Did the Big Bang create dark matter?
Post by: thedoc on 11/07/2016 15:49:14: If the Universe is comprised of 96% of dark matter/dark energy, do we have concrete proof the big bang actually created dark matter/dark energy?

Could it not be the case dark matter/dark energy already existed, and it was an interaction with an unknown particle and dark matter/dark energy which caused the big bang to occur?

If dark matter/dark energy is so dominant within the Universe, why should be hypothesize the big bang created dark matter/dark energy? We are basing this hypothesis on the 4% of matter we can see.

Title: Re: Do we have proof that the big bang created dark matter?
Post by: Atomic-S on 08/04/2016 07:25:03: Every discussion of dark matter and dark energy that I have ever seen, presupposes the existence of space and time in which they occur. A key question is whether, prior to the big bang, space and time even existed. If they did not, then the existence of dark matter and dark energy also become doubtful.
