Gravitational Waves: Ripples in Spacetime
Gravitational waves are ripples in the fabric of spacetime caused by violent cosmic events, such as colliding black holes or exploding stars. They were first predicted by Albert Einstein in 1916 as a consequence of his general theory of relativity. Gravitational waves carry information about the origins of the universe, providing a new way to understand gravity and explore the cosmos.
