Michelson-Gale experiment

C) Sagnac loop from the counterclockwise (A) loop [17]. It follows that the phase difference observed with platform at rest in the Sagnac effect [47] cannot be described by U(l) electrodynamics. This result is also consistent with the fact that the traditional phase of U(l) electrodynamics is invariant under T as discussed already in Section (III). The same result applies for the Michelson-Gale experiment [48], which is a Sagnac effect. 

This result is true for all matter waves and also in the Michelson-Gale experiment, where it has been measured to a precision of one part in 1023 [49]. Hasselbach et al. [51] have demonstrated it in electron waves. We have therefore shown that the electrodynamic and kinematic explanation of the Sagnac effect gives the same result in a structured vacuum described by 0(3) gauge group symmetry. 

In 1926 the Michelson-Gale experiment was confirmed by Pogany [14], who determined the surface velocity of the rotating earth by a closed optical...
