Why does light move?
From the theory of relativity, we learn that time is relative to the observer. And that time starts going slower and slower as the observer (reference point) moves faster and faster. And if the reference point reaches the speed of light (c), time stops, and if it theoretically surpasses it, time would go backwards.
Now, light travels at the speed of light, so if we consider a photon as the reference point, isn't time still for it? And if time is stopped, how does the photon ever get anywhere?
