First of all in physics there is no concept of massless body at rest.
Moreover the moving body always possess a mass along with it weather it is a photon or whatever
Photon has rest mass = ZERO(0)
But photon is never at rest
Moreover, photon in motion (quanta of light particle moving with
velocity c in vacuum) always has mass asscociated with it and
mass of the photon is given by m = hf/c^2

The Scientist does not study nature because it is useful; he studies it because he delights in it, & he delights in it because it is beautiful. If nature were not beautiful, it would not be worth knowing, life would not be worth living. Ofcourse I do not here speak of that beauty that strikes the senses, the beauty of qualities & appearances; not that I undervalue such beauty, far from it, but it has nothing to do with science; I mean that profounder beauty which comes from the harmoniuos order of the parts, & which a pure intelligence can grasp. |
