- The Scientists detected the most massive black hole merger ever recorded using gravitational wave detectors.
- The colliding black holes were 103 and 137 times the mass of the Sun.
- They are merging into a single black hole 265 times more massive than the Sun.
- The event occurred 10 billion light years from Earth and caused space-time ripples detected by LIGO.
- The black holes were spinning about 400,000 times faster than Earth.
- Scientists believe the black holes may have been formed from previous black hole mergers, explaining their large mass and rapid spin.
- So far, around 300 black hole mergers have been recorded, and this is the most massive and possibly most complex.
