The discussion clarifies misconceptions about the Big Bang Theory and black holes. The Big Bang Theory does not propose a singular creation event but describes a hot, dense state of the universe that evolved over time. It emphasizes that the early universe was characterized by rapid expansion, preventing the matter and radiation from collapsing into a black hole. The distinction between the expanding universe and the nature of black holes is critical to understanding why we do not live inside one.

It is unfortunate that you "know" that, since it's not true.Narasoma said:We know the Big Bang Theory states that our universe was started from a hot-dense point.
I suggest a forum search. the question has been answered here dozens of times as to why we don't live in a black hole.Narasoma said:But should't it became black hole and every matter and radiation pulled to singularity? We would not be her if that is the case.
A black hole is a vacuum spacetime. The Big Bang is based on a spacetime with matter everywhere. They are not equivalent.Narasoma said:But should't it became black hole and every matter and radiation pulled to singularity?
No. The matter and radiation in the early universe was expanding very rapidly. Far too rapidly for any of it to collapse to a black hole, even at the very high densities of the early universe.Narasoma said:should't it became black hole and every matter and radiation pulled to singularity?
