Can the speed of light be slowed down
WebLight slows down in a medium. Basically, the electric fields of the atoms slow down the light's propagation. What special and general relativity rely on is the speed of causality to be the same for all observers. The speed of causality is the fastest possible speed that any two things can interact at.
