WebJan 12, 2014 · This explains why nothing can travel faster than light – at or near light speed, any extra energy you put into an object does not make it move faster but just increases its mass. Mass and... WebSep 12, 2024 · the speed of EM waves is c in vacuum, when measured locally. EM waves have a speed in denser media less then c, because the wavefront slows down, but individual photons still travel at speed c, because they always travel in the vacuum between atoms in the material. this is why historically it is called speed of light.

The latest results from the Planck Collaboration et al. (2024) yielded a velocity of 369.82±0.11km/s which is slightly more than 0.1% of the light speed. Since Earth orbits the Sun with some 30km/s there's a small, biannual correction to this result. tainc
