Stephan Hawking states that there could have been a so called "Pre-Universe" or a universe before the Big Bang. Now Black holes he states can lose their mass because matter is somewhat able to escape. Thats why when you look at pictures of black holes you see that there is matter streaming at the poles at high speeds. Now when to much of this matter is ejected out the smaller the mass of the black hole. Now it is "said" that when the black hole finally loses all its mass and then implodes. Now this implosion is also said to release most of the matter in which the black hole ate. Well what if the big bang was actually a black hole in which it was born from a big star. Or it could be the merging of other black holes to create a massive black hole. Well its just a thought and if you guys have anything to say go ahead. This is just one of my bizzare ideas.
