Photon's mass is zero?(adsbygoogle = window.adsbygoogle || []).push({});

-----------------------------------

According to the SR's equation : m=m0/√(1-v2/c2), if the photon's velocity is the speed of light, then the photon's mass should be zero in value, but recently scientists have measured the photon having mass, but I forget the very long value of the photon mass.
