Comment on Could we send electric data across time?
robolemmy@lemmy.world 9 months agoAs I understand it, massless particles always have to move at the speed of light in the medium through which they’re moving. The catch is that it varies depending on the medium. The speed of light is only equal to c in a vacuum. Even in optical fibers, light speed is < c.

If I remember correctly only massless particles that travel through space are photons. Photons are what make up light so to say they travel at that speed is a little redundant.
