Is a photon completely massless? If not does light actually travel 99.9999......9% the quot;speed of lightquot;?Why does a photon travel at the speed of light? What cause it constantly be moving? Why isn't light static?
Why isn't light static? I suppose because it travels over distance, and that involves time. Light cannot travel at less than the speed of light (QED) so a photon is massless - if theories disagree, we have to chose one. Let me think! Static light? Consider that light, to you and me (and cameras etc), is a sensory perception. Yet a sensory perception exists between the plates of a capacitor without movement - it is tension, not movement. Light is tension, therefore is static.
