Asked by Janine Crockett
The Big Bang is said to represent a space-time singularity – the point in a black hole where space-time curvature is at a maximum and a point where no solid object can survive – but it didn’t originate from a black hole.
Instead, when you think about it – the Big Bang has more of a resemblance to the reverse of a black hole, called a white hole, since everything that we see today originated from that small point rather than being pulled into it. However, the Big Bang isn’t a white hole either.
What we do know, though, is that black holes are responsible for phenomena such as quasars rather than the Big Bang – so we shouldn’t expect any miniature Big Bangs occurring in the universe.
