Michelson–Morley Experiments cover

"The book should be an interesting read for advanced students within the field and for experts working in it."

Contemporary Physics

In 1887, Michelson and Morley tried to observe in laboratory the "ether drift" by measuring a small difference in the velocity of two perpendicular light beams. The result of their measurements, however, was much smaller than the classical prediction and interpreted as a "null result". This was crucial to stimulate the first pioneering formulations of relativity and, as such, it represents a fundamental step in the history of science. Since then, many repetitions of that original experiment have been performed with better and better sensitivity and the standard conclusion has been always the same: no genuine ether drift has ever been detected. However, in the authors' new scheme, the small irregular residuals observed in laboratory show surprising correlations with the direct observations of the Cosmic Microwave Background (CMB) with satellites in space. This opens the possibility of finally linking the CMB to a fundamental reference frame for relativity, with substantial implications for the interpretation of non-locality in the quantum theory. The importance of the issue would require new dedicated experimental tests and significant improvements in the data analysis. Otherwise, without such more stringent checks, these crucial experiments will remain forever as an enigma for physics and the history of science. The book illustrates the many facets of this research together with historical accounts on some leading scientists involved in these measurements.

"Starting with a fascinating, well-researched history of the notion of ether and attempts to detect its influence, the authors detail the Michelson-Morley experimental results before transitioning into a discussion of more recent ether-drift measurements."

CHOICE

"This book has the great and uncommon virtue of combining the fascinating tale of a crucial step in the history of science with the related research sections, where the substantial contributions made by the authors themselves in this exciting field are reviewed. While the tutorial part of the book has a captivating style, suitable to entertain a general readership, the research chapters expose in a critical approach, based on the authors’ thorough research work, the fundamental implications that Michelson-Morley’s (MM) experiments in their more recent versions are having on present astroparticle physics and cosmology. "
