A lot of people talk about the big bang, saying it created something from nothing - it is even used against the big bang. People say "it is impossible to create something from nothing." However, to my understanding, the big bang never created something from nothing. I have read it in many book and websites the the universe started of as an (arguably) infinitely dense point that contained everything, and that makes sense. George LeMaitre, who I think discovered to big bang, said that the universe had a beginning because if Hubble found that it is expanding, then it must have been smaller. Therefore it makes sense that the universe started of as a tiny point of infinite density, a singularity. So why do most people seem to think the big bang created something from nothing. Is it some kind of pop science over simplification?
