The discussion centers on the misconception that photons possess mass, which would imply they cannot travel at the speed of light. Participants clarify that black holes do not prevent light from escaping due to photon mass, but rather because of the curvature of spacetime caused by gravity. This curvature dictates that light follows a geodesic, reinforcing that photons are massless particles. The consensus is that the inability of light to escape black holes is not related to mass but to the nature of spacetime itself.
PREREQUISITESStudents of physics, astrophysicists, and anyone interested in the fundamental properties of light and gravity, particularly in relation to black holes.
No, that is not the reason that they cannot escape. Take a look at some of the similar discussions below or ZapperZ's statement in this thread.ganguly pranav said:If black holes were able to stop light from escaping , then would it mean that photons do have a certain mass (no matter how much negligible it is )
This issue has been discussed to death in several threads in both the Quantum physics forum, and the SR/GR forum. Please do your search there and figure out how gravity is a spacetime curvature, and why light follows the "geodesic" of that spacetime curvature. It has NOTHING to do with light having a mass.
