Gravity waves ripple through spacetime
Massive cosmic events like black hole mergers create gravitational waves, stretching and compressing the fabric of spacetime itself as they propagate.
Gravitational waves are disturbances in spacetime, much like ripples on a pond, generated by accelerating massive objects. Predicted by Albert Einstein over a century ago, these waves carry energy away from their source at the speed of light. Their direct detection in 2015 by the LIGO experiment, from the collision of two black holes, revolutionized astronomy, opening a new window into the universe.
