IF all the matter in the universe had ever been agglomerated into a point, it would still be there; that would amount to the biggest black hole of all time and nothing would ever escape from it. Big-bang is nothing more than a necessary artifact of an inadequate physical model based on a total misinterpretation of redshift phenomena, and nobody with brains or talent still believes in it any more than they do santa claus or the easter rabbit.
ROTFLMAO!!!
It is not even clear what time is at that point, let alone the claim that "that" is a blck hole. Also, it is a misconception that nothing can escape the black hole.
