The discussion revolves around the question of why the universe, which began in a hot-dense state as described by the Big Bang Theory, did not collapse into a black hole. Participants explore the implications of the Big Bang Theory and the nature of spacetime in relation to black holes.
Participants express differing views on the nature of the Big Bang and its implications for black hole formation, indicating that multiple competing perspectives remain without consensus.
There are unresolved assumptions regarding the definitions of the Big Bang and black holes, as well as the conditions of the early universe that may affect the discussion.
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?
