Gravitational waves, elusive ripples in space-time predicted by General Relativity, offer a captivating window into unraveling the mysteries of the universe. These subtle disturbances of the fabric of space-time, produced by cataclysmic cosmic events, were once thought impossible to detect, However, a century after their conception, the discovery of gravitational waves by the Laser Interferometer Gravitational-wave Observatory (LIGO) opened a new era of exploration. Gravitational waves emanating from the collision of massive black holes and neutron stars are now providing unparalleled insights into the cosmos, and working together with photons and neutrinos they gained a multi-sensory prospective of our understanding of the cosmos. The recent discovery from the pulsar timing array network has further expanded the reach of gravitational wave astrophysics to a new wavelength regime. This talk highlights the discovery of gravitational waves, explores their revelations about black holes, neutron stars, and cosmic history, and outlines future possibilities in gravitational wave astrophysics.
