The Michelson–Gale–Pearson experiment (1925) is a modified version of the Michelson–Morley experiment and the Sagnac-Interferometer.It measured the Sagnac effect due to Earth's rotation, and thus tests the theories of special relativity and luminiferous ether along the rotating frame of Earth.
The Michelson–Gale–Pearson experiment was a very large ring interferometer, (a perimeter of 1.9 kilometer), large enough to detect the angular velocity of the Earth. The outcome of the experiment was that the angular velocity of the Earth as measured by astronomy was confirmed to within measuring accuracy.
1925 – the Michelson–Gale–Pearson experiment produces a positive result while attempting to detect the effect of Earth's rotation on the velocity of light. The significance of the experiment remains debated to this day, but this planetary Sagnac effect is measured by ring laser gyros and taken into account by the GPS system.

Albert Abraham Michelson (surname pronunciation anglicized as Michael-son; December 19, 1852 – May 9, 1931) was a German-born American physicist known for his work on measuring the speed of light and especially for the Michelson–Morley experiment.
Michelson and Morley created an improved version of the Michelson experiment with more than enough accuracy to detect this hypothetical effect. The experiment was performed in several periods of concentrated observations between April and July 1887, in the basement of Adelbert Dormitory of WRU (later renamed Pierce Hall, demolished in 1962).

So this experiment either dismisses SR and an entrained aether, or it is consistent with both. Thanks, Hosh1313 ( talk ) 16:44, 23 September 2011 (UTC) [ reply ] Upon further thought, this is actually very embarrassing for Michaelson and, for the last 86 years, the entire physics community.
