The Michelson–Morley experiment was an attempt to measure the motion of ... This is in large part due to predictions of quantum gravity that suggest that special ...
The Kennedy–Thorndike experiment. The effects of special relativity can phenomenologically be derived from the following three fundamental experiments: [8] Michelson–Morley experiment, by which the dependence of the speed of light on the direction of the measuring device can be tested. It establishes the relation between longitudinal and ...
The predictions of special relativity have been confirmed in numerous tests since Einstein published his paper in 1905, but three experiments conducted between 1881 and 1938 were critical to its validation. These are the Michelson–Morley experiment, the Kennedy–Thorndike experiment, and the Ives–Stilwell experiment.
A big challenge for the Lorentz ether theory was the Michelson–Morley experiment in 1887. According to the theories of Fresnel and Lorentz, a relative motion to an immobile aether had to be determined by this experiment; however, the result was negative.
In 1925–1926, Dayton Miller performed interferometric observations at Mount Wilson, similar to the Michelson–Morley experiment, that appeared to reflect a measurable drift of the Earth through the luminiferous aether, in apparent contradiction with other experiments of that type and with relativity's prediction that no aether should be ...
Many tests of special relativity such as the Michelson–Morley experiment and the Kennedy–Thorndike experiment have shown within tight limits that in an inertial frame the two-way speed of light is isotropic and independent of the closed path considered. Isotropy experiments of the Michelson–Morley type do not use an external clock to ...
A much more precise experiment of this kind was conducted by David H. Frisch and Smith (1962) and documented by a film. [8] They measured approximately 563 muons per hour in six runs on Mount Washington at 1917m above sea-level. By measuring their kinetic energy, mean muon velocities between 0.995 c and 0.9954 c were determined.
An experiment to test the theory of relativity cannot assume the theory is true, and therefore needs some other framework of assumptions that are wider than those of relativity. For example, a test theory may have a different postulate about light concerning one-way speed of light vs. two-way speed of light, it may have a preferred frame of ...
