Results of a New Test of Relativity

Abstract

A modernized version of the classical Michelson-Morley experiment has recently been performed. The purpose of the experiment was to test the constancy of the velocity of light over a long baseline with light propagated one-way instead of back-and- forth. This was performed with instrumentation of the National Aeronautics and Space Administration Deep Space Network (DSN). In particular, measurements were made of the phases of two hydrogen maser frequency standards separated by 29 kilometers by propagating a laser signal over a highly stable fiber optics cable. Presented are the results obtained for measurements performed continuously during a full rotation of the Earth.
