Educational level : this is a secondary education resource. Educational level : this is a tertiary (university) resource. Subject classification : this is a physics resource . General Relativity , also known as the General Theory of Relativity , is an extension of special relativity , dealing with curved coordinate systems, accelerating frames of reference, curvilinear motion, and curvature of spacetime itself. It could be said that general relativity is to special relativity as vector calculus is to vector algebra. General relativity is best known for its formulation of gravity as a fictitious force arising from the curvature of spacetime. In fact, "general relativity" and "Einstein's formulation of gravity" are nearly synonymous in many people's minds. The general theory of relativity was first published by Albert Einstein in 1916.

General relativity Mathematical Physics index History Topics Index Version for printing General relativity is a theory of gravitation and to understand the background to the theory we have to look at how theories of gravitation developed. Aristotle 's notion of the motion of bodies impeded understanding of gravitation for a long time. He believed that force could only be applied by contact; force at a distance being impossible, and a constant force was required to maintain a body in uniform motion. Copernicus 's view of the solar system was important as it allowed sensible consideration of gravitation. Kepler 's laws of planetary motion and Galileo 's understanding of the motion and falling bodies set the scene for Newton 's theory of gravity which was presented in the Principia in 1687. Newton 's law of gravitation is expressed by F G M M d where F is the force between the bodies of masses M M and d is the distance between them. G is the universal gravitational constant. After receiving their definitive analytic form from Euler Newton 's axioms of motion were reworked by Lagrange Hamilton , and Jacobi into very powerful and general methods, which employed new analytic quantities, such as potential, related to force but remote from everyday experience.

References Derivation of Einstein's equations In what follows, we set . We will obtain Einstein's equations by varying the Einstein-Hilbert action with respect to the metric . We will also denote the contribution of matter to the action by , i.e., where Variation of Ricci scalar First, we need to develop some variational equations starting from the Riemann tensor whose variation is On the other hand, recalling the transformation law for the Christoffel symbols giving the Palatini identity The variation of the Ricci tensor is found by contracting indices Now, the Ricci scalar is , so that Here we have made use of the metric compatibility condition . Furthermore, the last term is a divergence , and will lead to a boundary term when integrated. Let us therefore write Variation of determinant Using Jacobi's formula for the derivative of a determinant , we find that Therefore Variaton of action Varying the action, we find

General relativity or the general theory of relativity is the geometric theory of gravitation published by Albert Einstein in 1916. It is the state-of-the art description of gravity in modern physics . It unifies special relativity and space and time, or spacetime. In particular, the curvature of spacetime is directly related to the four-momentum ( mass-energy and linear momentum ) of whatever matter and radiation are present. The relation is specified by the Einstein field equations, a system of partial differential equations The predictions of general relativity differ significantly from those of classical physics, especially concerning the passage of time, the geometry of space, the motion of bodies in free fall, and the propagation of light . Examples of such differences include gravitational time dilation, the gravitational redshift of light, and the

Special and General Relativity The special theory The general theory of relativity took seven years of work by Einstein, the final two to three being years of intense and exhausting labor. No one else was even close to Einstein's ideas. Had he not worked on them, they would most probably not have emerged then. We may not even have them today. In some ways, Einstein's theory is conservative. It is the last "classical" field theory in the sense that "classical" can mean "non-quantum." In another sense, it is anything but conservative. The theory is quite different from any theory before or after. It treats a force by means of geometry and eventually leads to startling notions: black holes, other universes and the bridges to them and even the possibility of time travel. All other theories of forces have been readily swept into quantum theory. General relativity has resisted and the problem of bringing general relativity and quantum theory together remains one of the most difficult, outstanding puzzles of modern physics.
