The Photon and Magnetic Monopoles
  The Energy-Length Rule implies the following properties for a transversal isolated system : on one side energy multiplied with zero component of x = both sign of ch, on the other side the sine of the p perpendicular to x, representing the helicity of the photon, is positive and negative. It corresponds to the sign of zero component of x, referring to the two cones which define respectively system and antisystem. The energy is obviously positive for both of them. Keeping p orthogonal to x implies right and left handed circular polarization simultaneously .Then in our interpretation the isolated real photon hides what we call the two monopoles. They are manifested in the real polarized photons being independent but united through their root as system and antisystem.
