Uh, I don't think universal movement works that way. Wouldn't the black hole have moved by the time we are where it was?
If I'm correct on how this works, it's a basic impossibility for us to ever be om-nom-nom'd by a Black Hole because everything within this Galaxy is constantly moving. Unless I'm wrong, I don't think anything in our path is a static we have to magically dodge.
What I'm getting at is, after the course of traveling through 50 million light years, to the point where this little black hole is, we aren't suddenly going to fall into it. Wouldn't it have moved by then, too?
Happily correct me if I'm wrong about this, but I read somewhere that the only way for us to randomly get screwed by a black hole is for one to magically pop up in our solar system.
