The Big Bang Theory attempts to explain the formation of the universe. What do you think the universe looked like before the Big Bang? What made the universe "bang?"

I think that brfore the Big Bang happened there were other nebulas and planets that we know nothing about because there was a black hole in the center of everything and the blach hole exploded and maybe distroied all of the planets that were already existing, but created the galexies that we see today.
