What is the speed of a photon falling in a black hole?
Can you tell me what is the speed of a photon falling in a black hole?
According to Einstein's theory of relativity, the speed of light remains constant in any reference frame. However, near a black hole, the gravitational force is so strong that it can bend the path of the light. As the light travels through the curved space-time near the black hole, it appears to slow down from an observer's perspective. But in reality, the light is still traveling at the speed of light.
