2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/201661We report Relativity tests based on data from two simultaneous Michelson-Morley experiments, spanning a period of more than one year. 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 $10^{-16}$, improved by factors between 3 and 50 compared to previous work.5 pages revtex, 2 figuresClassical PhysicsGeneral Relativity and Quantum CosmologyHigh Energy Physics - PhenomenologyHistory and Philosophy of Physicstext
