What is the velocity of a photon in a black hole?
That's interesting. Can you explain why the velocity of a photon in a black hole is different than other objects?
Sure. A black hole is a region of space where the compressive force of gravity is so strong that nothing, not even light, can escape. That's why the velocity of a photon in a black hole is limited to the speed of light.
