Was there a black hole at the big bang?
I was wondering about big black holes and whether or not before the Big Bang if there was a big black hole there?
No one actually knows what preceded the Big Bang. All we know is that when the Big Bang happened there was this massive amount of energy in a tiny amount of space. It appears that space itself has been expanding since the big bang so before then as far as we know there was no space. So we have no idea what was going on before the big bang.
Whether all of the mass all in one place at the big big should have created a black hole, or whether we would know if it did, I'm not sure.
