WebApr 1, 2014 · If a particle has no mass ( m = 0) and is at rest ( p = 0), then the total energy is zero ( E = 0). But an object with zero energy and zero mass is nothing at all. Therefore, if an object with no mass is to physically exist, it can never be at rest. Such is the case with light. WebJul 16, 2024 · And this was all well and good until Einstein came along a few decades later and realized that the speed of light had nothing to do with light at all. With his special theory of relativity ...

If they have mass (you can never measure something exactly), it has to be extremely tiny. Jan 4, 2015 #12 my2cts 362 26 Two more things: WebThis equation has been verified by many, many experiments and as far as we know is correct. The fact that momentum carries energy is even true in classical E & M where electromagnetic fields are involved. Since photons have zero rest mass then their energy is simply E = pc. The fact that light carries momentum is also verified by experiment. churchofann
