How does gravity escape a black hole?

Nothing escapes black holes, gravitons mediate gravity, so why do black holes gravitate?

My question is, "where is the hole (no pun intended!) in the above understanding?"

    Relevant Note: We do not yet have a generally accepted theory of quantum gravitation. – resgh Dec 05 '12 at 15:11
  • @DmitryBrant Thanks, I was unable to find that question. Should I delete this one? – user12345 Dec 05 '12 at 15:11
  • @user16307 The link works fine for me and points to a duplicate question for which many answers were posted. I would recommend this one be removed. – twistor59 Dec 05 '12 at 15:21
  • Sorry, there was a misunderstanding. "I was unable to find that question"... and that's why I made this one. But, when you (kindly) showed me the other question, I realised mine was redundant and so I asked if I should delete it. – user12345 Dec 06 '12 at 00:16

It is always virtual particles that "mediate" the interactions, not real ones. You imply real gravitons, not virtual ones; this is a hole in your reasoning.
