These figures were explained as
only a simple error of observation, or as being caused by differences in ambiant
This quasi-uncertainty allowed
Einstein to present his famous report on the Theory of Relativity, and the basis of the
hypothesis of the constancy of the velocity of light and the denial of the
existence of an ether.
However, it should be noted that after the new experiments
of Miller, Einstein wrote in a supplement of the Review Sciences in 1925 : "If
the observations of Dr. Miller are confirmed, the Theory of Relativity should be at fault.
Experiment is the only judge ".
Professor Allais, after having terminated his optical experiments of
sightings on sighting-marks, which confirmed the difference in velocity, then undertook a
statistical study of the important work of Miller.
It appeared that the observations of Miller were much
richer than had been estimated at the time of their publication, when they had gone almost
That's what brought Professor Allais to issue two important
notes on this subject. These notes were finally published by the French Academy of
Sciences, after two years of long discussions.
These two notes prove - in all cases - that
the results of Miller's experiments are positive and absolutely cannot be explained
as some alterations caused by variations of temperature.
