Einstein’s Theory of Relativity states that light (as it is travelling obviously at the speed of light) is so fast that it experiences no (zero) time. Obviously light does move a distance, as thats how we see things as the light bounces off of objects into our eyes, but surely with the equation ‘distance = speed\*time’ and time being zero it implies light doesn’t travel any distance?
In: Physics
Time isn’t zero. Time experienced by somebody sitting on a photon would be zero (or near zero – in the actual universe light often doesn’t travel at the speed of light). But photons travels within the frame of reference of the observer where d=st operates as usual. Photons travel in time – they just don’t ‘know’ that they’re doing it.
