Invariant (physics) — In mathematics and theoretical physics, an invariant is a property of a system which remains unchanged under some transformation.The gravitational field of the Sun is invariant under a change of time (from, say, now to tomorrow). It is also… … Wikipedia
Speed of gravity — Bei der Aberration der Gravitation handelt es sich um einen Effekt, der aufträte, wenn man das newtonsche Gravitationsgesetz unter bestimmten Bedingungen mit einer endlichen Gravitationsgeschwindigkeit kombiniert. Dieses Problem wurde schließlich … Deutsch Wikipedia

Variable speed of light — The variable speed of light (VSL) concept states that the speed of light in a vacuum, usually denoted by c , may not be constant in some cases. In most situations in condensed matter physics when light is traveling through a medium, it… … Wikipedia
Lorentz transformation — A visualisation of the Lorentz transformation (full animation). Only one space coordinate is considered. The thin solid lines crossing at right angles depict the time and distance coordinates of an observer at rest with respect to that frame; the … Wikipedia
History of special relativity — The History of special relativity consists of many theoretical and empirical results of physicists like Hendrik Lorentz and Henri Poincaré, which culminated in the theory of special relativity proposed by Albert Einstein, and subsequent work of… … Wikipedia
Maxwell's equations in curved spacetime — Induced spacetime curvature In physics, Maxwell s equations in curved spacetime govern the dynamics of the electromagnetic field in curved spacetime (where the metric may not be the Minkowski metric) or where one uses an arbitrary (not… … Wikipedia
