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

The black holes – one roughly 140 times the mass of the Sun and the other about 100 solar masses – fused into one pit of infinitely deep darkness 225 times larger than our Sun. The event, called GW231123, took place possibly billions of years ago about between two and 13billion light-years away.
