Observation of Highly Significant Correlations Between Earth Motion and Fringe-Shifts in a Stationary Michelson-Morley Experiment During the Period 2003-2005
Hector A. Munera
The fringe-shifts produced in a stationary Michelson-Morley (MM) interferometer were recorded every minute in each session lasting from 24 hours to a week; more than 40 sessions were carried out during the period from the end of 2003 to the beginning of 2005. Diurnal variations of the fringe-shifts were observed in all cases; after subtraction of environmental pressure, temperature and humidity contributions the residual curves still depict similar cyclic behavior. Both the uncorrected and the residual fringe-shift curves were correlated against the projection of earth's velocity on the plane of the interferometer. The earth velocity at each instant was calculated using the value of solar velocity obtained from the COBE observations. The declination of solar motion that maximizes the correlation with our data is obtained. For comparison, a similar exercise is carried out for Miller's velocity.
