Discuss this further, I still like that whole Big Bang theory. But I don't think humans will EVER figure out what the VERY beginning was, because I think there has been something going on forever, as with both of our preferred theories, something caused the whole atomic stuff to hit the fan, causing the big bang, which therefore something had to have caused it. Same with your Black Hole thing, something had to have caused the explosion.
Also, I don't think the whole Black Hole theory your talking about is right, because if there was nothing before the black hole, then the black hole couldn't exist, because black holes are created by the death of a star gone supernova, or something like that.
