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.

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.

A puzzling gravitational wave was detected, and astronomers have determined that it comes from a record-breaking black hole merger
