But wouldn't that throw everything out of balance? Shouldn't we be seeing some physical effects of the enormous amounts of gravity that would be involved in that. Shouldn't our solar rotation be affected by such a thing?

Don't take this the wrong way, but you clearly have no concept of the scale of the universe and how physics in general works. If there was a giant black hole, let's say 1 trillion solar masses, sitting 150-250 million light years away, our solar system would continue going about its business without nary a care. Only once it got to within a few hundred light years would there start to be destabilizing effects. At 10^12 solar masses, it would need to be within 10^6 AU to exert as much gravity upon the Earth as our sun does. That's roughly 6 light years. Certainly our orbit would become unstable long before that, perhaps at several hundred light years. But I suppose the outer planets would be perturbed once it got within a few thousand light years. Still, a few thousand << 150-250 million.
