Why couldn't there be a build-up of matter BEFORE the big bang? (There is no need to imagine black holes in the creation process)Quote from: sophiecentaurIt could be simply a matter of Energy. If there was enough kinetic energy 'inside' your imagined 'black hole' then the black hole could still have expanded into a non-black-hole. Most of what we say about black holes involves their formation from 'conventional' material falling in whereas the BB was a non standard situation.You have found the key.  The BB was a non-standard situation. It didn't follow our standard rules of nature.
