Gravitational waves are ripples in the curvature of spacetime, generated by the acceleration of massive objects, such as merging black holes or colliding neutron stars. These propagating distortions cause space itself to stretch and squeeze perpendicular to the direction of wave travel. The detection of these waves is achieved using highly sensitive instruments, often advanced interferometers that measure minute changes in the distance between separated mirrors. The observation of these waves represents a crucial tool in astrophysics, enabling scientists to study extreme cosmic events and probe the structure of the universe through methods independent of traditional electromagnetic radiation.
