WEB10 May 2024 · General Relativity makes specific predictions about how the light emitted from material in the inner-most regions around a black hole is distorted and gravitationally redshifted. Detailed observations of that light will provide stringent tests of strong gravity.
Tests of general relativity - Wikipedia
WEB2 days ago · Tests of general relativity serve to establish observational evidence for the theory of general relativity. The first three tests, proposed by Albert Einstein in 1915, concerned the "anomalous" precession of the perihelion of Mercury, the bending of light in gravitational fields, and the gravitational redshift.
