General Theory of Relativity


General Theory of Relativitysearch for term

"Space tells mass how to move" while "mass tells space how to curve" -- J.A. Wheeler. A mathematical model created by Albert Einstein in the years 1909-1916. It describes gravity as curvature in space-time, the four-dimensional fabric of our universe. His theory is the best model for gravity so far, and has been confirmed in experiments and observations. According to the theory, measurements made in time and space are not absolute, but relative to an observer's particular point of view, or reference frame. However, regardless of point of view (as measured by speed and direction), the speed of light is unchanged. The consequences of the laws of General relativity include concepts such as black holes, parallel universes, worm holes, and space-time.
