History's Most Significant Gravitational Wave Detections

The landmark events that moved gravitational wave physics from theoretical prediction to a primary tool for observational astronomy.

The top 3

1. GW150914: The First Direct Detection: The 2015 detection of binary black hole merging confirmed Albert Einstein's 1915 prediction, marking the birth of gravitational wave astronomy.
2. GW170817: First Multi-Messenger Observation: The collision of two neutron stars observed in both gravitational waves and electromagnetic light, revolutionizing our ability to map cosmic events.
3. The Nanograv 15-Year Background Signal: A 2023 breakthrough providing evidence for a persistent hum of gravitational waves originating from supermassive black hole binaries throughout the universe.
