Precision test for the new Michelson-Morley experiments with rotating cryogenic cavities
M. Consoli
Abstract
A new ether-drift experiment in Düsseldorf is currently measuring the relative frequency shift of two cryogenic optical resonators upon active rotations of the apparatus. I point out that the observed fractional amplitude of the sidereal variations of the signal in February, Csid (11 2) 10-16, is entirely consistent with the expectations based on Miller's observations in the same epoch of the year. This leads to predict that, with future data collected in August-September, the observed sidereal variations should increase by + 70 %, i.e. up to Csid (19 2) 10-16 retaining the present normalization. This would represent clean experimental evidence for the existence of a preferred frame.
