Do things really need to be limited?

[robvalue]

I suppose if the gravity was infinite, it would no longer matter how far away an object is from the black hole, the pull would be an infinitely large force. 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.
