This leads to the Big Question: why is all this stuff here?
The problem with this question, is that it presupposes a reason. There is no reason, it's just there. Chances are we will never find out what preceded and caused the big bang.

Dmitri wrote:(to continue to derail this even further...) I bet it's infinite (in time and space), i.e. Big Bang wasn't "the beginning" of everything. If anything (pun intended ), it was a beginning of a cyclical expansion of the part of the universe that we happen to be capable of observing. When I was in my teens, a friend and I had visualized this model of infinite collection of "bubbles" (each bubble being what we deem "observable universe"), pulsing between the BB state and the state of having expanded to the point where various forces would start pulling it all back together, until it reached the BB-level super-dense "dot". Back and forth, forever.
