General Relativity
General relativity is a geometric theory of gravitation that describes gravity as the curvature of four-dimensional spacetime shaped by mass, energy, and stress.
Overview
In this framework, mass, energy, momentum, and pressure curve spacetime, while freely falling objects and light follow geodesics through that geometry. The equivalence principle posits that gravitational acceleration is locally indistinguishable from inertial acceleration. Einstein's field equations formally relate the metric curvature of spacetime to the stress-energy tensor.
Why it matters
The theory accounted for anomalies such as Mercury's perihelion precession and predicted gravitational deflection of light, gravitational redshift, and gravitational waves. It provides the theoretical basis for modern relativistic astrophysics and relativistic cosmology.
