Why scientists think photon is mass-less ?
There are a bunch of values from various experiments that can be said to be a measured value of the mass of the photon .. A photon mass ranges from 10^{-7} eV – 10^{-27}. With such wide range of a mass we still have a firm founding on why photon can not be taken to…
