Discovery of Gravitational Waves

The discovery of gravitational waves was like detecting ripples in spacetime caused by massive cosmic events, such as merging black holes. Predicted by Einstein a century ago, these waves are distortions traveling through the universe. Scientists used highly sensitive detectors, like LIGO, to observe tiny changes in the distance between mirrors caused by passing waves. In 2015, LIGO directly observed gravitational waves for the first time, confirming Einstein’s prediction and opening a new way to observe the universe. This breakthrough provides insight into extreme astrophysical phenomena and expands our understanding of the fundamental nature of gravity.
