On earth we have a high escape velocity. This amounts to 11.2 kilometers per second. Yet we have relative freedom of movement perpendicular to the gravitational field. Inside the event horizon should be similar. Perpendicular travel should be easier with one caveat. The g forces will act to draw mass to the singularity at a greater rate than can be achieved by perpendicular motion. However, at the horizon the escape velocity, being equal to c will allow photons to travel across the surface of the horizon. With g forces at any one point being less than escape velocity the photon should be able to remain in a stable orbit. This light would still be invisible to outside observers and the object would still be entirely black. The surface of the horizon, if it comprised of a mass would be considered a perfect absorber. None of the light would emit and would be absorbed by electrons at the surface. This in itself should show that no mass can be present at the event horizon as electrons would gain unlimited amounts of energy over time. When this is taken into consideration it can be determined that collapse does in fact continue beyond the horizon.
