In general relativity, this remaining precession, or change of orientation of the orbital ellipse within its orbital plane, is explained by gravitation being mediated by the curvature of spacetime. Einstein showed that general relativity [3] agrees closely with the observed amount of perihelion shift. This was a powerful factor motivating the ...
The Eddington experiment was an observational test of general relativity, organised by the British astronomers Frank Watson Dyson and Arthur Stanley Eddington in 1919. The observations were of the total solar eclipse of 29 May 1919 and were carried out by two expeditions, one to the West African island of Príncipe , and the other to the ...

These three experiments justified adopting general relativity over Newton's theory and, incidentally, over a number of alternatives to general relativity that had been proposed. Further tests of general relativity include precision measurements of the Shapiro effect or gravitational time delay for light, measured in 2002 by the Cassini space probe.
In a 1964 article entitled Fourth Test of General Relativity, Irwin Shapiro wrote: [1] Because, according to the general theory, the speed of a light wave depends on the strength of the gravitational potential along its path, these time delays should thereby be increased by almost 2 × 10 −4 sec when the radar pulses pass near the sun. Such a ...
So far, all tests of general relativity have been shown to be in agreement with the theory. The time-dependent solutions of general relativity enable us to talk about the history of the universe and have provided the modern framework for cosmology, thus leading to the discovery of the Big Bang and cosmic microwave background radiation.
[p 1] [p 2] It was proposed by Robert Pound and his graduate student Glen A. Rebka Jr. in 1959, [p 3] and was the last of the classical tests of general relativity to be verified. [ p 4 ] The measurement of gravitational redshift and blueshift by this experiment validated the prediction of the equivalence principle that clocks should be ...
