Talk:White Hole Creation/@comment-3568954-20170925094544/@comment-34372069-20180304061207

Actually, according to futurism and the very definition, of a white hole, literally pushes you away by spitting material at you. This is the reverse of a black hole: A white hole spits out everything and nothing goes in. So while a black hole has an event horizon that, once you get close enough, you can never escape, a white hole has an event horizon that you can never even get close to (and that is not even counting the burning that you would get when you try!).

However, one of the theoretical consequences of general relativity is the existence of "closed singularities", points where space (and matter contained in that space) is sucked into an infinitely small point where time comes to an end. These objects are known as black holes. Mathematically, the opposite situation can be envisioned, '''where space (and matter) is spewed forth from an infinitely small point where time begins. '''Again, for symmetry reasons, these hypothetical objects are referred to as "white holes". Because gravity attracts, rather than repels, it is easy to see how black holes would form, but not a white hole. The only "white hole" in existence that ever fits that description is the Big Bang, the even from which all space, time, matter, and energy originated, thereby creating the universe. Why there should have been a Big Bang, or any universe at all, is a question that science cannot answer yet. Basically, general reletivity is what hinders the possibility of a white hole existing.
