The whole thing makes my head hurt. When was the beginning of reality? Matter just always existed? It's all exploding outward for billions of years until what, it starts receding back in for billions of years until its a big hot ball of goo again? Are we just trapped in the Battlestar Galactica universe, this has all happened before and it will all happen again?

I need a nap.

Im casting my vote for it’s already happened and will again. If we ever develop the ability to travel far enough I wouldn’t be surprised if we discovered evidence predating our expectations of the Big Bang.

I heard an astronomer explaining the eventual heat dealthbifbtue universe will leave it full of protons and nothing else. He then said that because photons don't 'experience' space, that such a state would be indistinguishable from the conditions thought to exist immediately before the big bang.

I'm probably misexplaining it, but it was quite mind-blowing.
