General relativity - Wikipedia
WEB1 day ago · General relativity, also known as the general theory of relativity and Einstein's theory of gravity, is the geometric theory of gravitation published by Albert Einstein in 1915 and is the current description of gravitation in modern physics.
Tests of general relativity - Wikipedia
WEB1 day 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.

WEB28 May 2024 · Example of General Relativity. An excellent example of General Relativity in action is the phenomenon of gravitational lensing. Gravitational lensing occurs when the gravitational field of a massive object, such as a galaxy or a cluster of galaxies, bends the path of light from a more distant object behind it.
Relativistic Lagrangian mechanics - Wikipedia
WEB1 day ago · Examples in general relativity General relativistic test particle in an electromagnetic field. In general relativity, the first term generalizes (includes) both the classical kinetic energy and the interaction with the gravitational field. For a charged particle in an electromagnetic field, the Lagrangian is given by
