Astronomers have detected the signal of a colossal black hole in deep space that likely formed when two already-large black ...

Two colossal black holes—among the most massive ever seen—collided in deep space, creating gravitational waves that rippled across the cosmos and shook the foundations of astrophysical theory.

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

“It’s the most massive [merger] so far,” says Mark Hannam, a physicist at Cardiff University, UK, and part of the LVK ...
