Evidence for nonzero mass photons associated with a vacuum-induced dissipative red-shift mechanism

Laboratory observations that suggest a frequency anisotropy in the direction of the Leo constellation of delta nu / nu >or=10/sup -6/ can be interpreted in terms of a nonzero photon mass m/sub gamma / equivalent to 10/sup -65/ g. If one then accepts the theory of light (considered as real Maxwellian waves and photons simultaneously) of Einstein and de Broglie, the experimental justification of the existence of real Maxwellian displacement currents implies the existence of m/sub gamma />0 and of a vacuum dissipative mechanism which can interpret a part (or the totality) of Hubble's cosmological red shift.<
