Einstein equation for gravity
The Einstein field equations (EFE) may be written in the form: where is the Einstein tensor, is the metric tensor, is the stress–energy tensor, is the cosmological constant and is the Einstein gravitational constant. The Einstein tensor is defined as where Rμν is the Ricci curvature tensor, and R is the scalar curvature.

WebMar 24, 2024 · To answer, Einstein made use of his new, powerful theory that described gravity as the curvature of spacetime around a mass. The more massive a body, the more warped the geometry around it is, and the slower time ticks. Einstein’s reasoning was crystal clear. Since his theory allowed him to calculate how the Sun’s mass bends space … WebNewtonian gravity is an instantaneous force, i.e., action at a distance, coupled to gravitational mass (conceptually different from inertial mass ). General Relativity is a local theory (no action at a distance). Einsteinian gravity is the curvature of spacetime and the coupling is between mass-energy and geometry; "matter tells spacetime how ...

General relativity replaces Newton's theory of universal gravitation as the most complete theory of gravitation. Newton and Eddington were English. Einstein was German. 1919 was the first year after World War I. Anti-German sentiment was still high in Europe.
