That's a pretty interesting question. I asked a friend of mine who is doing a Ph.D. in theoretical physics that question and his answer was "I don't know". It seems that a black hole distrupts space-time so much that it is hard to do Quantum Field theory in its neighborhood. It is field theory that will tell you what a graviton might do. Oh well. If you don't worry about gravitons, gravity from a black hole can be thought of as a massive distortion of space-time due to the hole's great mass. Another guy said that physist's knew the answer, but are keeping everybody in the dark. - Dwight -
