My question is are these photons stationary? Or are they falling back into the singularity? If they fall back, that means the acceleration of the gravitational field exceeds that of the speed of light, which is not possible under our current scientific understanding. If the escape velocity is exactly the speed of light, that means there are photons sitting stationary inside the event horizon.

I'm sure something is amiss here. I'm probably using mechanics to explain relativity...
