Has the speed of light changed
WebAug 15, 2024 · 1. The simplest explanation: Light consists of photons, sub-atomic particles of light. These photons have no mass. Special Relativity tells us that any massless object has to travel at the speed of light. It cannot travel at any other speed whatsoever. That is why the photons travel only at the speed of light (in vacuum), and no other speed.
