An international team of physicists discovered the largest-ever merger of 2 black holes through a phenomenon known as gravitational waves.

The powerful merger, designated GW231123, produced an extremely large black hole about 225 times the mass of our Sun.

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