Precision test for the new Michelson-Morley experiments with rotating cryogenic cavities

TL;DR

This paper analyzes a new cryogenic optical resonator experiment testing ether drift, showing that observed sidereal variations align with historical Miller data and predicting increased signals in future measurements, supporting the existence of a preferred frame.

Contribution

It provides a precision test of ether drift using rotating cryogenic cavities and correlates current results with historical Miller observations, predicting measurable future variations.

Findings

Observed sidereal variations are consistent with Miller's historical data.

Predicted increase in sidereal variation amplitude in upcoming measurements.

Supports the hypothesis of a preferred frame in physics.

Abstract

A new ether-drift experiment in D\"usseldorf 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, C_sid \sim (11 \pm 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 \sim + 70 %, i.e. up to C_sid \sim (19\pm 2) 10^{-16} retaining the present normalization. This would represent clean experimental evidence for the existence of a preferred frame.
