Taylor and John Archibald Wheeler Addison Wesley Longman Albert Einstein told us that a star or other massive object distorts spacetime in its vicinity. Sufficient distortion makes it impossible to describe matter and motion with the single "inertial reference frame" used in Newton's theory of mechanics and Einstein's theory of special relativity. General relativity describes the distortion of spacetime near a star, white dwarf, neutron star, or black hole and predicts the resulting motion of stones, satellites, and light flashes. Learning general relativity usually requires mastering Einstein's field equations, which are expressed in the complicated mathematics of tensors or differential forms. But big chunks of general relativity require only calculus if one starts with the metric describing spacetime around Earth or black hole. Expressions for energy and angular momentum follow, along with predictions for the motions of particles and light. Students study the Global Positioning system, precession of Mercury's orbit, gravitational red shift, orbits of light and deflection of light by Sun, the gravitational retardation of light, and frame-dragging near a rotating body.

General relativity From Wikipedia, the free encyclopedia. Two-dimensional visualization of space-time distortion. The presence of matter changes the geometry of spacetime, this (curved) geometry being interpreted as gravity. General relativity (GR) or general relativity theory (GRT) is a geometrical theory of gravitation and cosmology published by Albert Einstein in . In this theory: Spacetime is treated as a curved 4-dimensional Lorentzian manifold Spacetime is curved by the presence of mass energy and momentum (or stress-energy ) within it; The relationship between stress-energy and the curvature of spacetime is governed by the Einstein field equations ; and Inertial motion occurs along timelike and null geodesics of spacetime. In general relativity, gravitation is not due to a force . Instead, phenomena that in classical mechanics are ascribed to the action of the force of gravity (such as freefall orbital motion, and spacecraft trajectories ) are taken in general relativity to represent inertial motion in a curved spacetime. So what people standing on the surface of the Earth perceive as the 'force of gravity' is a result of their undergoing a continuous physical acceleration caused by the mechanical resistance of the surface that they are standing on.

Home First Prev [ 1 Next Last In general relativity Einstein's field equations can be derived from an action principle starting from the Einstein-Hilbert action where g is the ( pseudo Riemannian metric R is the Ricci scalar n is the number of spacetime dimensions and k is a constant which depends on the units chosen (see below). In Brans-Dicke theory k is replaced by a scalar field. In general relativity, the action is assumed to be a functional of the metric only, i.e. the connection is given by the Levi-Civita connection . Some extensions of general relativity assume the metric and connection to be independent however and vary with respect to both independently. The Einstein-Hilbert action is said to have been written down first by the german mathematician David Hilbert 1 Derivation of Einstein's field equations The Einstein-Hilbert action as stated above will actually yield the vacuum Einstein equations.
