Gowdy solution

Gowdy universes or, alternatively, Gowdy solutions of Einstein's equations are simple model spacetimes in general relativity which represent an expanding universe filled with a regular pattern of gravitational waves. ^[1]

Einstein field equations

The Einstein field equations (EFE; also known as Einstein's equations) comprise the set of 10 equations in Albert Einstein's general theory of relativity that describe the fundamental interaction of gravitation as a result of spacetime being curved by mass and energy.

Expansion of the universe

The expansion of the universe is the increase of the distance between two distant parts of the universe with time.

General relativity

General relativity (GR, also known as the general theory of relativity or GTR) is the geometric theory of gravitation published by Albert Einstein in 1915 and the current description of gravitation in modern physics.

Gravitational wave

Gravitational waves are the disturbance in the fabric ("curvature") of spacetime generated by accelerated masses and propagate as waves outward from their source at the speed of light.
