For more than a century, the Michelson–Morley experiment has stood as a cornerstone of modern physics — the “crucial experiment” that seemed to disprove the existence of the ether and paved the way for Einstein’s theory of relativity.

Yet, what if Michelson’s famous null result did not mean the absence of the ether, but rather the limits of classical optics?

In this groundbreaking study, Dimitrie Olenici and Ștefan Bogdan Olenici-Crăciunescu revisit Michelson’s experiment through the lens of kinetic optics — a new approach in which light reflected by moving mirrors behaves differently than in static conditions. Through detailed calculations, experimental data, and a critical re-examination of Michelson’s assumptions, the authors show that the absence of fringe shifts can be fully explained by the phenomenon they call kinetic reflection.

Combining historical analysis, theoretical rigor, and original experimental results, this book invites readers to reconsider one of the most iconic experiments in the history of science — not as a failure, but as a door toward a deeper understanding of light, motion, and the nature of space itself.
