I saw a very old post where someone asked where an electron gets it's charge. Where does the charge come from? Doesn't it arise from the interaction with photons? My understanding is that electric charge and magnetism can not exist without photons, and the electron itself most likely could not exist independent either, a kind of relativistic quality. Can a single photon ever exist in a void without electrons? I don't think so. I suppose that the electromagnetic force is created by an exchange of photons between charges, but is the charge itself also created by this photon interaction?
