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

Astronomers have recorded gravitational waves from the largest ever black hole collision detected. Two behemoths merged in a cataclysmic event 10 billion light years from Earth. The cosmic giants, weighing 103 and 137 times the mass of our sun,

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.
