Do photons experience time? If they move at the speed of light then special relativity states that they do not, but then does that mean they do not move forward in time which means the distance they travel is instantaneous (thus it is infinitely fast), which we know is not true (as they move at the speed c). Furthermore, what happens when a photon ceases to exist? How does it cease to exist? Does it hit my body and 'poof' it is gone? what is process by which photons end their life.
