“The idea of all the matter in the universe being compressed to a singularity that somehow did not collapse into a black hole from which no matter could escape was always completely unscientific. It’s merely a religious creation myth dressed up in scientific language.”
Luckily, that is not what is proposed by the Big Bang theory, so you can stop worrying about it.
“Luckily, that is not what is proposed by the Big Bang theory...”
No? So you are saying that Big Bang theory does not propose that all the matter in the universe could be contained within a space smaller than the Schwartzchild radius of all the matter in the universe, and then later escape that radius?
