Ever her of the inflationary theory?
So one day a couple of the universes bumped into each other, heat was created and that precipitated the hadrons.
We live in one of those infinite, ageless universes. We are adjacent to all the others as well.
There is no beginning beyond the creation. Everything we have observed is merely the operation of a very small part of it. At the moment we are basking in the light which was created AFTER the first creation.
In fact, the "stars" we see today were mostly all created long after the original creation of the very large hydrogen fusion reactions that created the heavier elements found in all of today's stars.
Ever her of the inflationary theory?
Sure. Just read a good article on it in the Economist. It is a descriptive theory of what happened (space increased in size) without explaining how or why it expands. It just says that it does. There is no empirical reason for it to expand--it just fits with observation with no rationale for the motive power behind it that offsets gravity.
Now there are also theories of negative gravity and a fifth force that counteracts it--but no experimental evidence for them.
