The Mansouri–Sexl theory is a well known test of the theory of relativity. The main test theories of special relativity (SR) are named after their authors, Robertson (Rev. Mod. Phys. 21, 378 (1949)) and Mansouri and Sexl (Gen. Rel. Grav. 8, 497 (1977); 8, 515 (1977); and 8, 809 (1977)). These test theories can also be used to examine potential alternate theories to SR — such alternate theories predict particular values of the parameters of the test theory, which can easily be compared to values determined by experiments analyzed with the test theory. The existing experiments put rather strong experimental constraints on any alternative theory. Mansouri and Sexl promised an electromagnetic version of their theory, but for some reason that part was never delivered. In the following paper, we will construct the electromagnetic version and will demonstrate its application to constraining light-speed anisotropy. PACS No.: 03.30.+p

Special Relativity Theory

Between 1937 and 1953 the industrial physicist Herbert E. Ives pursued an extended research program with the aim of challenging the acceptance of relativity theories, and became the most important American opponent of Einstein during that era. As part of his anti-relativistic efforts Ives also performed the famous Ives-Stilwell experiment. Usually interpreted as the first direct confirmation of the time dilation formula of special relativity theory, this experiment was regarded by Ives as proof of what he called the Larmor-Lorentz theory. Ives’s heterodox views about relativity were mainly ignored by the scientific community during his lifetime. After his death, however, his criticisms of what the majority of physicists took for granted helped spark philosophical discussions in the late 1950s concerning the conventional stipulation of distant simultaneity in special relativity theory. Ives’s anti-relativistic beliefs and actions allow for an analysis of the heterodox efforts of an accredited member of the scientific community and the subsequent process of his professional marginalization in a specific historical and scientific context. This paper has three aims: to uncover the epistemic roots of Ives’s opposition to relativity; to analyze Ives’s rhetorical strategies and the reasons why he failed to persuade his peers; and to reveal the divergence between the public network of allies Ives built in scientific publications and the hidden network of allies present in his correspondence. It will become clear that the hardening of Ives’s tone against relativity and Einstein can be understood in light of his progressive marginalization and loss of recognized socioprofessional identity due to his unorthodox ideas. Ives’s case is illuminating for the historical, philosophical, and sociological perspectives it provides on the complex mechanisms by which the margins interact with the mainstream of science, both in the production of certified knowledge and in the contextually contingent redefinition and reconfiguration of the boundaries of acceptable scientific discourse.

Anisotropy Measurement

The Mansouri–Sexl theory is a well-known test theory of relativity. In the following paper we demonstrate a novel way of detecting second-order effects in terms of both lab and ion speed for light speed anisotropy detection. Prior literature15,18–21 has shown the way of constraining the Mansouri–Sexl parameter "a" via the Ives–Stilwell experiment, however, the prior approaches have proven to be incomplete in managing to constrain only one parameter, the "a" parameter. In the current paper we will take the unprecedented step of reconstructing the Mansouri–Sexl formalism for the Ives–Stilwell experiment and by showing how to improve on the theoretical and experimental bases such as to constrain both the parameter "a" and the parameter "b". Our paper is organized as follows: in the first section we give a new and more complete derivation of the Mansouri–Sexl Doppler effect. In the second part, we apply the newly expanded Mansouri–Sexl Doppler formalism in order to revise the principles of the Ives–Stilwell experiment. We continue by showing how the revised experiment is to be used in order to constrain both the parameter "a" and the parameter "b" in a measurement of light speed isotropy. This turns the Mansouri–Sexl Ives–Stilwell experiment into a very powerful tool for constraining light speed anisotropy.
