WebField Equations & Equations of Motion (General Relativity) Velocity is a vector (tensor) or vector (tensor) field. In familiar notation, the velocity v is represented by v = v e where v represent the components of the velocity, and e represent basis (unit) vectors in the selected coordinate system.

WebMar 27, 2024 · In the equation, the increased relativistic mass ( m) of a body times the speed of light squared ( c2) is equal to the kinetic energy ( E) of that body. Explaining E … General relativity has emerged as a highly successful model of gravitation and cosmology, which has so far passed many unambiguous observational and experimental tests. However, there are strong indications that the theory is incomplete. The problem of quantum gravity and the question of … See more 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 See more General relativity can be understood by examining its similarities with and departures from classical physics. The first step is the realization that classical mechanics and … See more General relativity has a number of physical consequences. Some follow directly from the theory's axioms, whereas others have become clear only in the course of many years of research … See more Gravitational lensing The deflection of light by gravity is responsible for a new class of astronomical phenomena. If a massive object is situated between the astronomer and a distant target object with appropriate mass and relative … See more Soon after publishing the special theory of relativity in 1905, Einstein started thinking about how to incorporate gravity into his new relativistic framework. In 1907, beginning with a … See more The derivation outlined in the previous section contains all the information needed to define general relativity, describe its key properties, and … See more Neo-Lorentzian Interpretation Examples of prominent physicists who support neo-Lorentzian explanations of general relativity are Franco Selleri and Antony Valentini See more Webgeneral relativity an extension of special relativity to a curved spacetime. The third key idea is that mass (as well as mass and momentum flux) curves spacetime in a manner ...
