Einstein’s doubt:

Einstein: “I believe that I have really found the relationship between gravitation and electricity, assuming that the Miller experiments are based on a fundamental error. Otherwise, the whole relativity theory collapses like a house of cards.” (Letter to Robert Millikan, June 1921 in Einstein: The Life and Times, p. 400).

 

Einstein to astronomer Erwin Freundlich in 1913: “If the speed of light is in the least bit affected by the speed of the light source, then my whole theory of relativity and theory of gravity is false” (ibid., p. 207).

Einstein: “My whole theory of relativity and theory of gravity is false.”  And so, they are Einstein.  Miller was right pace the first quote, and Sagnac was right confirming the second quote

Einstein’s house of cards

Georges Sagnac’s experiments, which disproved the constancy of the speed of light, and proved an ether, were rather miraculously, incorporated, and consumed by ‘The Science’ to support time dilation and STR!  Sagnac’s effect, which is used in GPS, measurement, and gyroscope technologies, disproved STR of course.  Sagnac proved there are absolutes when measuring light speed and the ether which STR does not support.  Experiments using Sagnac’s method which followed his 1913 effort, also found the same.  Not a single Relativist can point to an experiment disproving Sagnac. 

Sagnac never confronted Einstein and his fantasy-world directly.  But Dayton Miller did.  Miller like those before him who registered negative results when trying to prove STR and the Earth’s orbit around the Sun, was a Copernican Sunworshipper.  He was a very well-known American physicist and a key figure in the US science establishment.  He was not a man to be ignored.

Dayton Miller’s biography in summary:

·       PhD in science in 1890 from Princeton University

·       President of both the American Physical Society (1925-1926) and Acoustical Society of America (1913-1933)

·       Chairman of the division of Physical Sciences of the National Research Council (1927-1930)

·       Chairman of the physics department of Case School of Applied Science (aka: Case Western University)

·       Active member of the National Academy of Sciences.

During a 31-year period from approximately 1902-1933, Miller produced over 300.000 experimental tests which confirmed the 19^th and early 20th century’s interferometer measurements including Sagnac’s, that no mechanical mobility or motion of the Earth could be detected, and there appeared to be an ether.  Miller’s experimentation is the most thorough and detailed study in history of trying to prove heliocentricity and the Earth’s movement through an ether.  All he found was that the Earth appeared immobile and that an ether acted on the Earth. 

Miller Time

So, what did Miller do?

Dayton Miller constructed (to paraphrase Joe Biden), the most extensive and sophisticated interferometer experiment in history.  Miller built the largest and most sensitive collection of equipment ever devised to record and measure the ‘interference’ readings of light beams.  As a devout Copernican he was simply trying to prove the theory of heliocentricity and STR.

Miller took great care with his creation.  At extraordinary cost he floated the interferometer device on a pool of mercury to eliminate friction.  He employed different bases including, wood, metal and concrete.  Miller performed tests at different times of the day, different seasons of the year, different altitudes, including the Mount Wilson observatory near Pasadena California, and at different latitudes with differing light sources.  He produced his observations over a 3 decade long period. 

Miller also took precautions against thermal distortions by insulating the apparatus in one- inch cork and by applying uniform parabolic heaters and taking account of human body heat.  He covered the interferometer in glass so that drift would not be inhibited.  He used a 50x magnification telescope to observe the fringes, which allowed him to see down to the hundredth scale.  Miller even switched to an interferometer made of aluminum and brass to eliminate possible effects from magneto-constriction.

It was a comprehensive and largely incorruptible setup.  Beyond reproach or critique. 

The first round of testing ensued from 1902-1916, when Miller performed over 200,000 different readings.  By contrast, the 1887 Michelson-Morley had a total of 36 readings on an apparatus that was much smaller and less accurate.  The second round occurred between 1921 and 1933, when Miller performed over 100,000 trials (D. C. Miller, “The Ether-Drift Experiment and the Determination of the Absolute Motion of the Earth,” Reviews of Modern Physics 5, 352-367, 1933). 

In total we have some 300.000 measurements.
