General relativity - Wikipedia
WEB1 day ago · These decompositions show that the spacetime evolution equations of general relativity are well-behaved: solutions always exist, and are uniquely defined, once suitable initial conditions have been specified. Such formulations of Einstein's field equations are the basis of numerical relativity. Global and quasi-local quantities
General relativity | Gravitational Waves, Spacetime & Cosmology
WEB2 May 2024 · The solution of the field equations that describe general relativity can yield answers to different physical situations, such as planetary dynamics, the birth and death of stars, black holes, and the evolution of the universe.
Maxwell's equations - Wikipedia
WEB3 days ago · The covariant formulation (on spacetime rather than space and time separately) makes the compatibility of Maxwell's equations with special relativity manifest. Maxwell's equations in curved spacetime, commonly used in high-energy and gravitational physics, are compatible with general relativity.
Tests of general relativity - Wikipedia
WEB3 days ago · Gravitational-wave astronomy can test general relativity by verifying that the observed waves are of the form predicted (for example, that they only have two transverse polarizations), and by checking that black holes are the objects described by solutions of the Einstein field equations.

WEB4 days ago · Mathematics of Gravitational Waves in General Relativity. References. What are Gravitational Waves? To say that gravitational waves are propagating disturbances in the curvature of spacetime means that gravitational waves affect the distances measured between objects as they pass through them.
