          • VIRTUAL PHOTON


            from Rod Siddall Added 118 0 0

            A PHOTON JUMPS BETWEEN TWO ELECTRONS. To conform to the law of conservation of energy, the photon is of course a virtual photon. Two charge-carrying elementary fermions (in this case electrons) are mediated by a force-carrying elementary boson (in this case a photon.) Therefore its path is sealed within the image, between the electrons, in accordance with classic Feynman diagrams, which we've sketched in generically to keep things simple. So crucial to existence yet so hard to visualise...if anyone can do a better job filming/representing this QED phenomenon, let us know!
