3Einstein Field Equations
A set of ten equations in General Relativity that describe the fundamental interaction of gravitation as a result of spacetime being curved by matter and energy.
Gravitational Waves
Ripples in spacetime caused by some of the most violent and energetic processes in the Universe.
Black Holes
A region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it.
