## Main Question or Discussion Point

First, a question. I assume that a photon can be captured into a stable orbit around a black hole. It seems it would just be a function of the radius of the event horizon and the velocity of the photon (always

If my first assumption is correct, that would indicate that there is a "shell" of photons in stable orbit around any black hole. Now, say there was some matter falling into the black hole. As it approached the event horizon, it would collide with and scatter these orbital photons. Would that account for some of the light emitted from a black hole as it consumes matter? It seems that for any black hole of significant age, there would be an unfathomable amount of energy locked in orbit around the black hole in the form of gamma and x-rays, not to mention visible light and radio waves. When that collided with infalling material, it seems like it would make a great show :)

*c*I know but the vector is the important part). Where would this stable orbit be in regard to the event horizon? Would it be some small distance away from the event horizon, or at the very limit?If my first assumption is correct, that would indicate that there is a "shell" of photons in stable orbit around any black hole.
