   The question is why can gravitons (if they exist) escape from
black holes.  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.
