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
