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

Scientists have observed the largest black hole merger ever detected, marking a historic breakthrough in astrophysics. The colossal event occurred around 10 billion light-years from Earth and was observed through powerful gravitational waves picked up by detectors like

The event is the most massive black hole merger ever recorded by gravitational wave detectors and has forced physicists to rethink their models of how the enormous objects form. The signal was recorded when it hit detectors on Earth sensitive enough to detect shudders in space-time thousands of times smaller than the width of a proton.
