Photon has mass

WebSummary. The energy has a mass and it can be massless also. The energy that a particle possesses is due to its mass and momentum. For the massless particle, the energy that it gains is from the momentum and the speed of such particles which are massless moves with a speed equal to light particles. ← Previous Post. WebRegardless of the photon generator characteristics, onboard photon rockets powered with nuclear fission and fusion have speed limits from the efficiency of these processes. Here it is assumed that the propulsion system has a single stage. Suppose the total mass of the photon rocket/spacecraft is M that includes fuels with a mass of αM with α < 1
