Modern Tests of Special Relativity

Physics Today, 1987
From our perspective one hundred years after the fact, the null result of the Michelson-Morley ether-drift experiment clearly marked the beginning of the end for the Newtonian notions of absolute space and time. At the time, however, it took 20 years of work by H. A. Lorentz, Henri Poincaré and others for most physicists to come to the same conclusion.

Tests of Special Relativity

, 2017
With the mass-energy \(m=E(v=0)/c^{2}\) relation, all pivotal properties of special relativity have been now derived and we consider the related status of SR tests. 1) There are direct tests exploring i) the speed of light in different context, ii) the time dilation, iii) the body contraction, and iv) mass-energy relation.

Modern Optical Tests of Special Relativity

2007 European Conference on Lasers and Electro-Optics and the International Quantum Electronics Conference, 2007
In this paper, the authors give a detailed report on a specific such clock comparison, which can be viewed as a modern descendant of the classical Michelson-Morley experiment testing the isotropy of the speed of light.

NEW OPTICAL TESTS OF SPECIAL RELATIVITY

Laser Spectroscopy, 2004
Special Relativity (SR) is a fundamental theory that underlies all established models of the forces of nature, from the gravitational and electromagnetic to the weak and strong nuclear forces. Violations of SR, however, seem to be a common feature of many proposed models of quantum gravity, like string theory and loop gravity.

Significance of precision tests of special relativity

Physics Letters A, 1993
Abstract Recent experiments using two-photon absorption and phase comparison of masers can set bounds on Lorentz-violating preferred-frame alternatives to special relativity, but cannot give empirical knowledge concerning the one-way speed of light, since the latter depends on the synchronisation convention.

Tests of special relativity using the Doppler effect

Proceedings of the IEEE, 1976
The classical and relativistic Doppler shifts are compared for light incident at any angle upon a perfectly reflecting mirror moving in any arbitrary direction. It is shown that experiments designed to test the theory of special relativity in reflecting systems must be accurate up to third order in v/c.
