Hey is light made of electrons or protons? I know that all matter in existence is made up of a combination of those two. I figure it is one of each that way that the total charge is 0 and it's all neutral and stuff (and due to the symmetry of the universe and all that) but i'm not sure. I tried to look it up but it wasn't really clear it said online that it was a photon but I know that's just a sci-fi kind of term (that they use in Star Trek and stuff). So can anyone clear this up?
