general relativity

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 gravity is a consequence of matter causing a curvature in spacetime.


(ˌrɛl əˈtɪv ɪ ti)

1. the state or fact of being relative.
a. Also called special relativity. the first part of Einstein's two-part theory, based on the axioms that physical laws have the same form throughout the universe and that the velocity of light in a vacuum is a universal constant, from which is derived the mass-energy equation, E = mc2.
b. Also called general relativity. the second part, a theory of gravitation based on the axiom that the local effects of a gravitational field and of the acceleration of an inertial system are identical.
3. dependence of a mental state upon the nature of the human mind.

According to this theory, dynamical phenomena occurring in a curved space-time like black holes can be described by a theory on a flat space-time, just as a hologram can record the information of 3D objects on a plane.

Extensions of these standard formalisms are then examined, including grand unified theories, scalar-tensor theories of gravity, quantum field theory in curved space-time, supersymmetry and supergravity, and models of phase transitions during the primordial universe, and their different implications for primordial cosmology are explored.
He developed the principle of equivalence so that he could proceed mathematically; this resulted in a curved space-time.
