The only thing stopping the whole of the rest of the universe being swallowed up into it instantly would be the "speed of gravity". No other finite gravities would matter anymore.
However, if there were competing black holes all with infinite gravity, everything would get sucked into the nearest one.
Since none of this has happened, they can't be infinite
I just made all that up, I'm not qualified to answer. But that is my guess, based on observation. What the theoretical problems are I have no idea. E=m*c*c, it would be an infinite amount of energy. Not cool I guess.
That sort of makes sense, but apparently there is a super massive black hole at the center of most galaxies, and the gravity is strong enough to keep the entire galaxy orbiting it, so even Earth is affected by the black hole at the center of the milky way. I would also think that the universe expanding is the reason why a blackhole can't just swallow everything. Black holes also expel beams of energy which I guess is just the matter they swallowed up converted into energy to keep things balanced.
