Sometime in 1979 while gazing at the poster of the Andromeda galaxy in my bedroom, it suddenly dawned on me that a spiral galaxy looks something like water going down a drain. Water went down the drain; matter goes down the black hole "drain." Seemed pretty obvoius at the time. Now it looks like that most, or evan all galaxies contain central "feeding" black holes. To take it a step further, eventually all galaxies will gobble up thier matter, until there's nothing left but black holes. What next? Black holes moving away from eachother forever? Or finally attracting eachother, and combining into one single super-duper-massive black hole? Maybe that event causes a recurring big bang?
Yeah, maybe too simplistic.
