10. According to some models, all forces must be mediated by particles
In these models, I believe that gravity is assumed to be mediated by a "graviton", although nobody has ever identified such a particle.

Now, I'm pretty sure that particles cannot escape the event horizon of a black hole (ignoring Hawking radiation).

So, is the gravity that we perceive around a black hole from gravitons that are created outside the event horizon? It seems as though they must be. Otherwise, the particle model of gravity must be a bit dodgy.

Then again, my grasp on particle physics is most definitely dodgy. Any physicists out there to straighten me out?
