US EditionTwo Monster Black Holes Just Collided — It’s so Massive, It Shouldn’t Exist
GLOBAL NETWORK OF LIGO (USA), VIRGO (ITALY), AND KAGRA (JAPAN) OBSERVATORIES, JUL 15 – The GW231123 merger formed a 225-solar-mass black hole, exceeding previous records and challenging current stellar evolution and black hole formation models, scientists said.
- On November 23, 2023, the LVK Collaboration observed a record-breaking black hole collision that combined two black holes, around 100 and 140 times the Sun’s mass, producing a single black hole estimated at approximately 225 solar masses.
- This merger involved black holes of around 100 and 140 solar masses, which challenge standard stellar evolution models and suggest complex formation scenarios.
- The detection occurred during LVK's fourth observing run, using gravitational waves to observe ripples in spacetime caused by the collision of these enormous black holes.
- Physicist Mark Hannam remarked that this black hole binary is the largest detected so far through gravitational waves, while Gregorio Carullo highlighted that deciphering the complex signal will require several years of analysis.
- This breakthrough advances our knowledge of how black holes form and highlights the importance of enhancing gravitational-wave detectors and refining models of stellar evolution.

WDC TV NewsTwo monster black holes just collided — it’s so massive, it shouldn’t exist
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. Detected by the LIGO-Virgo-KAGRA observatories, this record-breaking merger has stunned scientists not only because of its size, but also due to the black holes’ extreme spins, challenging our current understanding of how such behemoths form.
When massive stars collapse, black holes can be created. However, it can also be different. This suggests a signal of gravitational waves measured in the USA.
Biggest Black Hole Merger Ever Detected May Reveal a Missing Link in the Universe
Scientists have detected the biggest black hole merger. Credit: 852278-MCS / CC BY-SA 4.0 In what may be a breakthrough in astrophysics, scientists have observed the biggest black hole merger ever recorded—an event that could offer the strongest evidence yet for a long theorized and rarely glimpsed class of black holes. The collision occurred near the edge of the Milky Way galaxy and produced a single black hole estimated to be about 225 times t…
Largest black hole merger ever observed found by LIGO-Virgo-KAGRA gravitational wave detectors
The largest black hole merger ever observed has resulted in a new black hole about 225 times the mass of our Sun. The collision was detected using the LIGO gravitational wave observatories.

These waves, first postulated by Einstein in his general theory of relativity, are ripple…
