The Laser Interferometer Gravitational-wave Observatory (LIGO) is no stranger to making history and breaking records. In 2015, its twin detectors based in Livingston, Louisiana, and Hanford, Washington, made the first ever detection of gravitational waves.

New gravitational wave findings from the LIGO-Virgo-KAGRA Collaboration report the discovery of the largest black hole merger ever. It could lead to evidence of an extremely rare type of black hole.

A physics conference has received a report of the gravitational wave from the heaviest pair of black holes we’ve so far observed merging. The result is larger than theoretical models allow through straight-forward means,
