Einstein field equations - Wikipedia
WEBIn 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.
General relativity - Wikipedia
WEBGeneral relativity generalizes special relativity and refines Newton's law of universal gravitation, providing a unified description of gravity as a geometric property of space and time or four-dimensional spacetime. In particular, the curvature of spacetime is directly related to the energy and momentum of whatever matter and radiation are ...
Einstein Field Equations (General Relativity) - The University of …
WEBWhat Does It Mean? 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 …
General Relativity - University of Cambridge
WEBGeneral relativity is the theory of space and time and gravity. The essence of the theory is simple: gravity is geometry. The effects that we attribute to the force of gravity are due to the bending and warping of spacetime, from falling cats, to orbiting spinning planets, to the motion of the cosmos on the grandest scale. The purpose of
How to understand Einstein’s equation for general relativity
WEBSep 15, 2021 · In general relativity, the fact that we have four dimensions (three space and one time) as well as two subscripts, which physicists know as indices, means that there is not one equation, nor...

WEBThe first is actually a set of equations called Einstein's field equations; the left-hand side encodes the curvature of spacetime while the right-hand side encodes the matter/energy content. The second, called the geodesic equation, governs how the trajectories of objects evolve in a curved spacetime.

Einstein Field Equations (Chapter 3) - The General Theory of Relativity
WEBEinstein used three principles to develop his general theory of relativity. 1. Mach's Principle: Ernest Mach gave some ideas without any proof and arguments that are known as Mach's principle. There are several forms of Mach's principle. Some forms are executed in general relativity and others are not.
