Black Holes and Galaxies

Black holes have the same gravitational pull as any other object of the same mass. If the Sun was collapsed into a black hole Earth's orbit wouldn't change. The weird stuff only happens when you start to get closer to the center of gravity than you would have been able to before (since you'd hit the surface, and then part of the mass would be behind you).
