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.

In the general theory of relativity, the Einstein field equations (EFE; also known as Einstein's equations) relate the geometry of spacetime to the distribution of matter within it.
c =. speed of light in a vacuum (a universal, and apparently unchanging constant) The greater the speed of the moving observer, the closer the ratio v2/c2 is to one, the closer the denominator √ (1 − v2/c2) is to zero, the more the time dilates, stretches, enlarges, or expands.
May 2, 2024 · General relativity follows from Einstein’s principle of equivalence: on a local scale it is impossible to distinguish between physical effects due to gravity and those due to acceleration. Gravity is treated as a geometric phenomenon that arises from the curvature of space-time.

The Einstein Field Equations are ten equations, contained in the tensor equation shown above, which describe gravity as a result of spacetime being curved by mass and energy. is determined by the curvature of space and time at a particular point in space and time, and is equated with the energy and momentum at that point.
General relativity is Einstein's theory of gravity, in which gravitational forces are presented as a consequence of the curvature of spacetime. In general relativity, objects moving under gravitational attraction are merely flowing along the "paths of least resistance" in a curved, non-Euclidean space.
