The surface gravity of a Schwarzschild black hole is said to be inversely proportional to the mass of the black hole. But if the event horizon represents the "point of no return" even for light, then I would have thought that the surface gravity must have a fixed relationship to the speed of light, and hence should be the same for all black holes regardless of mass. Why am I wrong?
