LIGO Scientific Collaboration
The LIGO Scientific Collaboration (LSC) is a group of scientists focused on the direct detection of gravitational waves, using them to explore the fundamental physics of gravity, and developing the emerging field of gravitational wave science as a tool of astronomical discovery.

Exceptional tests of general relativity with GW250114
In January 2025, the LIGO-Virgo-KAGRA collaboration observed an exceptionally loud gravitational-wave signal: GW250114. It stands out as the clearest one observed thus far, about three times louder than the first detection in 2015. The signal matches what is expected when two black holes of nearly equal mass and low spin spiral together, collide, and settle into a single, larger black hole. Because of… Read More
