Machine Systematics in Dayton Miller’s “Ether Drift” Interferometer Revealed by Analysis of Variance

Authors: Simon WW Manley

The copious data records from Dayton Miller’s heroic experiments have been analyzed and re-analyzed for nearly a century by authors wishing to reinstate some version of an ether theory with a preferred frame of reference. These authors claim that a small but significant signal at the period of half a rotation in the Miller data represents anisotropy in the propagation of light, the “ether drift” effect sought in Michelson and Morley’s 19th century experiment. The analysis of variance presented in this paper, however, shows a component at the period of a full rotation, which can only be a systematic in the machine or the observer. The magnitude of the systematic matches that of the component at the half-rotation period. The remarkable aspect of the story is that the implications of the full rotation systematic, which comprehensively invalidates the claim that the data reveals an “ether drift,” or any other meaningful physics, has gone virtually unnoticed for nearly 100 years.
