  • Gravitational Waves: Ripples in Spacetime

    Introduction Gravitational waves are ripples in the fabric of spacetime, predicted by Einstein’s General Theory of Relativity (1915) and first directly detected in 2015 by LIGO (Laser Interferometer Gravitational-Wave Observatory). These waves are generated by the most violent cosmic events—merging black holes, neutron stars, and supernovae—and provide a new way to observe the universe. 1.…
