I was trying to fall asleep last night and began to ponder about the universe. This isn't something unusual, it helps me sleep. But I came across a thought that stood out from the previous ones that I simply discarded. Shortly after reading a few chapters of "A brief history of time" I became focused on black holes. And I previously read a few articles on super-black holes....the ones found at the center of a galaxy. Anyways, I began to ponder, what if all the matter being taken-into a black hole is merely being pushed out the "other end". What if a duplicate universe exists on the other side of a black hole, one that expulses the matter taken from our universe, into another. This could explain why our galaxy revolves around such a mass, and where it goes..... Just a thought, was wondering if you can support/discard this theory? Seems to follow most of the previous theories....other than the ever-expanding universe.....which could still fall into the bigger picture though.
