History

Historical Context

In 2015, the LIGO observatory made a groundbreaking discovery by detecting gravitational waves, confirming Einstein's 1916 prediction. This event marked the first direct observation of such waves, resulting from the merger of two black holes. The detection, announced on February 11, 2016, initiated a new era in astrophysics, enhancing our understanding of cosmic phenomena and leading to the establishment of the Gravitational Wave Transient Catalog.
