What wasbefore the big bang?
This is where you have to be able to comprehend time and infinity.
Time began with the big bang, so nothing could have happened before the big bang, because it was the first thing to have happened.
One possibility is that the universe existed before the big bang. Depending on the critical mass of the universe (which we don't know yet) the universe could begin to colapse on itself, creating the big crush, which is basicaly the opposite of the big bang, and the universe would end as it started. Once the universe has colapsed, the big bang will happen again, and things will play out exactly the same as they did last time.
So we have all been here an infinate number of times before, reborn.
Actualy, due to the nature of time, this is both the first time, the last time, and everything between, all at once.
Realy weird to think of that isn't it?
But that's just a possibility, we don't know if there is enough mass in the universe so that gravity pulls us back into one centre point again.
Just thought I'ld give you lot a little science lesson there.
