I have a little question: If the light cannot escape out of the black hole, how is it possible that there are planets and stars spining around them? The cause of this spinning is the force of gravity. Taking into account it is said that gravitational interaction is transported via gravitons (virtual particles). This particles go at light velocity. If this light cannot escape, the body spinning around black holes should not know this black hole is there, because black hole couldn't emit gravitons.

It seems to me an enigma!.
