We report relativity tests based on data from two simultaneous Michelson-Morley experiments, spanning a period of more than 1 yr. Both were actively rotated on turntables. One (in Berlin, Germany) uses optical Fabry-Perot resonators made of fused silica; the other (in Perth, Australia) uses microwave whispering-gallery sapphire resonators. Within the standard model extension, we obtain simultaneous limits on Lorentz violation for electrons (5 coefficients) and photons (8) at levels down to 10…

Direct terrestrial test of Lorentz symmetry in electrodynamics to 10−18

Over the past 25 years, a spaced based test has been been proposed to measure nearly every aspect of General Relativity from gravitational waves to tests of Einstein’s Equivalence Principle. To date,…
