The world revolves around...a black hole?

Well, not just the world, but our entire galaxy, actually. I know it sounds weird, but hey, black holes are really cool! I mean, the only objects that can actually trap light?! How cool would it be if you could actually see one? (though technically if no light leaves it, you can't see one, but you could see the absense of light which would tell you where one is).

The thing that facinates me about this, even more than the black hole is that astronomers can see into the center of the galaxy, even through all the stars and space "stuff" like dust and debries between us and the center. It's technology amazing?!
