On R.T. Cahill’s Re-analysis of the Michelson-Morley Experiment

Authors: Henok Tadesse

R.T. Cahill has been advancing a new approach to the analysis of the Michelson-Morley experiment. He proposed that length contraction completely cancels the effect of absolute motion only in vacuum (n=1).He has proposed a re-analysis of the experiment by taking into account the refractive index of the medium (air), thereby explaining the origin of the small fringe shifts observed in the Michelson-Morley and the Miller experiments. In this paper we present two cases against Cahill’s theory. 1. He may have overestimated the velocity predicted by his own theory by a factor of about 1.4. 2. His theory cannot explain the ‘null’ result of the Kennedy-Thorndike experiment, even in vacuum.
