Einstein's theory of gravity, in which the force of gravity is reinterpreted as a curvature of spacetime in the vicinity of a massive object.
a generalization of special relativity to include gravity (based on the principle of equivalence)
Einstein's theory that matter, space, and time are linked. The gravity of any mass, such as our Sun, deforms or warps the space-time around it and this in turn will alter the path taken by any objects (or light) that pass close by.
Einstein's version of the laws of physics, when there is gravity. Building on the Special Theory of Relativity, this theory generalizes Einstein's work so that the laws of physics must be the same for all observers, even in gravity. Einstein showed that gravity is best understood as a warping of the geometry of spacetime, rather than as a pulling of objects on each other. The crucial idea is that objects move along geodesicsâ€”which are determined by the warping of spacetimeâ€”while spacetime is warped by massive objects according to the formula = 8 Ï€
states that all physical laws can be formulated so as to be valid for any observer, regardless of the observers motion
It formulates how gravity bends space-time and it is used to explain and understand the large-scale structure of the universe.
the geometric theory of gravitation developed by Albert Einstein, incorporating and extending the theory of special relativity to accelerated frames of reference and introducing the principle that gravitational and inertial forces are equivalent. The theory has consequences for the bending of light by massive objects, the nature of black holes, and the fabric of space and time.
Einstein's generalization of special relativity that makes all observers, whatever their sates of motion, essentially equivalent. Because of the equivalence principle, general relativity is necessarily a theory about gravity.
"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. See also Einstein, Albert Special Theory of Relativity
