(Continuation of article on Home page) Maurice Allais, initially, carried out his own experiments which led him to observe the existence of phenomena incompatible with the commonly accepted theories. He drew from them his own conclusions according to which the velocity of the light does not have a constant value but varies (slightly) according to the direction. This approach led him to show the existence of ether (in ancient times known as "aether"), the upper regions of air which fills up space beyond the clouds, and of the anisotropy of space (space exhibits properties with different values when measured in different directions). In a second time and to consolidate his own results, Maurice Allais was brought to reexamine the detail of the results of the experiments which had been carried out in the past on the same subject in the USA by Michelson and Morley in 1887, by Morley and Miller in 1902, 1904 and 1905, and by Miller in 1925, 1926 and 1930. Allais then could observe that these results contain the same anomalies which were not noticed at the time by the experimenters or were neglected. Maurice Allais affirms today with force that these anomalies are real and indisputable and that they call into question the laws of relativity, discovered by Lorentz and Poincaré, and more known under Einstein.
