| photon |
a quantum of electromagnetic radiation, usually considered as an elementary particle (boson) that is its own antiparticle and that has zero rest mass and charge and an experimentally measured spin of one. The propagation of a photon (retarded wave EM quanta) requires the presence of its time reversed conjugate (advanced wave EM quanta) which must propagate backwards through time from the target. ...
