Gravitational Waves are 'Ripples' in spacetime caused by massive objects moving at high speeds, like black hole mergers.
Predicted by Einstein’s general theory of relativity in 1915, gravitational waves carry energy across the universe.
Detectors like Laser Interferometer Gravitational-Wave Observatory (LIGO) use laser interferometry to measure tiny distortions in spacetime caused by passing waves.
Gravitational waves stretch and compress spacetime by incredibly small amounts (smaller than a proton’s width).
These waves are generated by violent cosmic events such as black hole collisions or neutron star mergers.
In 2015, LIGO made the first-ever detection of gravitational waves, confirming Einstein’s century-old prediction.
