Hey, well I've just been having a discussion with someone this minute, about traveling at the speed of light. We said that for something to travel at the speed of light, the partcile will need to be massless, but when I looked it up, I found that a particle has to have mass? Does a photon have a mass? It can be made to go faster than the speed of light? How does that work? I mean, how can something with mass, travel faster than the speed of light?
