The Pound–Rebka experiment of 1959 measured the gravitational redshift in spectral lines using a terrestrial 57 Fe gamma source over a vertical height of 22.5 metres. This paper was the first determination of the gravitational redshift which used measurements of the change in wavelength of gamma-ray … See more In physics and general relativity, gravitational redshift (known as Einstein shift in older literature) is the phenomenon that electromagnetic waves or photons travelling out of a gravitational well (seem to) lose See more Astronomical observations A number of experimenters initially claimed to have identified the effect using astronomical measurements, and the effect was … See more • Tests of general relativity • Equivalence principle • Gravitational time dilation See more Uniform gravitational field or acceleration Einstein's theory of general relativity incorporates the equivalence principle, which can be stated in various different ways. One such statement is that gravitational effects are locally undetectable for a … See more The gravitational weakening of light from high-gravity stars was predicted by John Michell in 1783 and Pierre-Simon Laplace in 1796, using See more WebAs explained above, when this equation is coupled with gravitational redshift experiments, it shows that antimatter must fall down with an acceleration within 0.04% of that of ordinary matter. Start with a chunk of matter and a chunk of antimatter, each of mass m (mass is always understood here to mean inertial mass), at the top of a tower of ...

The redshift is: This was tested by Pound and … WebNov 26, 2024 · Mössbauer effect to verify the gravitational redshift. "The tower used by Pound and Rebka in 1960 to exploit the Mossbauer effect is only about h = 20 meters high, and so the effect (gravitational redshift) is only ( G M / ( R c 2)) ( h / R) ∼ 10 − 15! How would one of do the experiment?”.
In the years subsequent to the series of measurements performed by the Pound lab, various tests using other technologies established the validity of gravitational redshift/time dilation with increasing precision. A notable example was the 1976 Gravity Probe A experiment, which used a space-borne hydrogen maser to increase the accuracy of the measurement to about 0.01%. From an engineering standpoint, after the launch of the Global Positioning System (which depen…
