Why do massless particles not experience time?
In: Physics
Relativity plays a role here. The faster an object goes, the slower it traverses through time. Objects with mass require energy to accelerate them, thus their velocity through space is limited and they will experience at least some passage through time. A massless object is not bound by this and can have the highest velocity in space that we currently believe is possible (the speed of light), and at that velocity, passage through time ceases.
