What's All this Shit Going on in Congress?

first of all, yes, the galazy does rotate.

That's an interesting theory, and you could be right, but I think the reason why black holes don't keep growing is because they're surrounded by the vacuum of space. They already pulled in all the matter that they could, and there's nothing left in range for them to pull. By "in range", I mean the gravitational radius, which is proportional to the black hole's gravitational pull. Even with an infinite amount of time, everything wouldn't necessarily get pulled into the center of the galaxy, because the gravity is only enough to create an orbital effect similar to the one for our solar system...or hold us in place. Does the galaxy spin? I'm not really sure.

whlie that would be a truthful statement, it fails to compensate for the additional mass gained by the assimilation of matter unto the black hole. with this additional material, the gravitational field grows and can therebye pull at thigns from a greater distance which is then absorbed into the mass, again increasing the gravitational field; thus the theory of exponential growth. and also even space is not a total vacuum, or so i've read.
