A detailed analysis of the Michelson-Morley ether drift experiment (from 1887 to 1926) contradicts the classical law of addition of velocities. The small ether drifts first observed by Michelson are not compatible with Newtonian Mechanics. This result paved the way for the first form of the Theory of Relativity in which light velocity is always equal to c in all directions, and no such drift is possible. It is shown in this letter that the introduction of a small photon mass mg ~ 10-65 gr. by Einstein, Schr?dinger, de Broglie et al implies a small anisotropy in the velocity of light (at each frequency) and the reintroduction of an observable absolute inertial frame. Consequently, in conjunction with Dirac's chaotic covariant ether distribution, this provides a relativistic interpretation of Michelson's 8.1 km/s absolute earth ether drift observation, later confirmed by Miller in 1933. More recent results are briefly discussed.
Six samples of objects have been analyzed in order to check whether the redshift asymmetry discovered by Rubin et al. is a general effect. The results for all samples are consistent with the existence of the asymmetry. Its average magnitude is = 1300 + 210 km/s. The asymmetry vanishes at large distances. Various interpretations of the effect have been discussed. Arguments are given in favour of a non-Doppler redshift occurring in the intergalactic space within the Local Supergalaxy and other concentrations of galaxies.
This article was written in 1975, and has remained unpublished until now. It is published here in the hope that it will stimulate fresh thinking on the controversial issue of non-velocity "cosmological" redshifts.
