Theory of relativity/General relativity - Wikiversity
Web5 Apr 2023 · General relativity ( GR ), also known as the General Theory of Relativity, is an extension of special relativity, dealing with curved coordinate systems, accelerating frames of reference, curvilinear motion, and curvature of spacetime itself. It could be said that general relativity is to special relativity as vector calculus is to vector algebra.

Web20 Feb 2022 · 28.1: Einstein’s Postulates. Relativity is the study of how different observers measure the same event. Modern relativity is correct in all circumstances and, in the limit of low velocity and weak gravitation, gives the same predictions as classical relativity. An inertial frame of reference is a reference frame in which a body at rest ...

WebThis is a general feature of Special Relativity: in the limit where the speed of light is effectively infinite these effects are unobservable and common sense prevails. This prediction of Special Relativity has been experimentally confirmed many times. For example the muon is a type of cosmic ray formed in the upper atmosphere. It is unstable ...

Web12 Jun 2015 · Confirmed by Arthur Eddington (1882–1944) England in 1919. 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.

WebSpecial relativity also produced the most famous equation ever written: E = mc2. It says that the energy ( E) associated with an object – an atom, a person or a whole galaxy – is equal to its total mass ( m) multiplied by the square of the speed of light (c). As the speed of light is about 300,000 km s -1, this means there is a whole lot of ...
