Some cosmologists speculate that black holes end their lives by transforming into their exact opposite — so-called 'white holes' that pour all the material they gobbled up back into space. A new theory based on quantum gravity could explain how this is possible.
It's mind blowin' time! According to a new theory, every black hole contains a smaller alternate universe. And our universe might just exist inside a black hole in a much larger universe. Ah-whaaaaaa?
