Because the speed of light cannot be exceeded, when the big bang happened, the matter that flew out could not have come out at the same time. If it did, the universe would be so crouded in it's first second, it would instantaniously create a large number of black holes swallowing most of the matter. Would it be logical to conclude the singularity from our big bang was a black hole in a larger universe, that did not truely explode at once, but rather over a period of time, possibly right at this moment... A white hole? I was watching long documentaries, and this concept just came in to my head. What do you people think? Am I thinking about it the wrong way?
