The Big Bang singularity gave rise to the entire universe, which includes Space, Time and all the matter that fills it. A similar type of singularity is a white hole – a theoretic object that arises in Einstein’s Theory of Gravity. It’s essentially a black hole in reverse. A point of singularity where matter is ejected. Consequently, some scientists have wondered if the universe could have been created from a white hole. The Universe s2e2: Cosmic Holes, History 2007
Physicists speculate that if nature uses white holes then they could have been an important element in the earliest stages in the universe. Perhaps even in the formation of the universe itself. ibid.
As a black hole collapses and matter falls into it perhaps the matter is blown out the other side in a white hole. Doesn’t that sound like the Big Bang? Professor Michio Kaku, interview How the Universe Works
According to the Big Bang theory all the universe suddenly sprang from a point of nothing. Could black holes be the key to explain how this happened? ... Instead of sucking everything in, a reverse black hole explodes out in a shower of Space, Matter and Time. Exactly as the Big Bang theory predicts. Professor Stephen Hawking
Black holes might even be gateways to other universes. On the other side of a black hole there could even be a big bang. How the Universe Works s1e2: Black Holes, Discovery 2010
