Scientists Record a Black Hole Collision They Weren’t Sure Was Possible
WASHINGTON AND LOUISIANA, JUL 16 – The merger produced a black hole about 225 times the Sun's mass, doubling the previous record and challenging existing black hole formation theories, scientists said.
- On November 23, 2023, LIGO detected gravitational waves from the most massive black hole collision recorded, occurring far beyond the Milky Way.
- This event happened as two black holes, each over 100 times the sun's mass and spinning rapidly, merged during LVK's fourth observing run.
- Scientists report that the collision resulted in a black hole with a mass estimated to range from approximately 190 to 265 times that of the sun, exceeding the previous heaviest observed black hole of around 140 solar masses from event GW190521.
- Professor Mark Hannam stated that this newly detected pair of black holes is the largest discovered through gravitational wave signals to date, posing significant questions for existing models of black hole formation.
- Researchers expect this discovery to deepen understanding of black holes, but Gregorio Carullo said it will take years to unravel the signal’s complex features.

The resulting black hole is 225 times the mass of the Sun. The colliding black holes were also remarkably massive.
Cosmic Heavyweights Collide – LIGO Detects Largest, Fastest-Spinning Black Holes Yet
A gravitational wave has revealed the biggest black-hole merger ever recorded—so massive and extreme, it defies current astrophysical models. The clash formed a 225-solar-mass monster, possibly made from black holes that had already merged before. Einstein’s rules may need revisiting. Record-Breaking Black Hole Collision The LIGO-Virgo-KAGRA (LVK) Collaboration has observed the most massive black hole [...]
The Most Massive Black Hole Merger Ever
Astronomers using the LIGO-Virgo-KAGRA gravitational wave detectors announced the most massive black hole merger ever seen. Two black holes crashed together, producing a final black hole with approximately 225 times the mass of the Sun. Designated GW231123, it was detected during the 2023 observing run, and appears to be from the collision of 100- and 140-stellar-mass black holes. Black holes this massive are hard to get through standard stellar…
