by Two black holes are collided far beyond the distant edge of the Milky Way, which has caused the greatest fusion that has ever been recorded by gravitational shaft detectors.
The two phenomena, more than 100 times the sun, gathered each other before they collided violently from earth about 10 billion light years.
Scientists from the Observatorios Ligo Hanford and Livingston discovered on November 23, 2023 when the two American detectors twitched in Washington and Louisiana at the same time.
In addition to its huge masses, the signal, which was called GW231123 after its discovery date, also showed the black holes, according to the researchers.
“This is the most massive black hole that we have observed through gravitational waves, and it is a real challenge for our understanding of black hole formation,” said Professor Mark Hannam from Cardiff University and member of the Ligo Scientific Collaboration.

Gravitation wave observatories have recorded around 300 mergers of the black hole.
Before GW231123, the most difficult identification was GW190521, the combined mass of which was 140 times the sun. The latest merger produced a black hole up to 265 times more massive than the sun.
“The black holes seem to turn very quickly – near the border through Einstein’s theory of general theory of relativity,” said Dr. Charlie Hoy from the University of Portsmouth.
“It makes it difficult to model and interpret the signal. It is an excellent case study to promote the development of our theoretical tools.”
“It will take years for the community to completely design this complicated signal pattern and all its effects,” said Dr. Gregorio Carullo, assistant professor at the University of Birmingham.
“Despite the most likely explanation that remains a black hole grip, more complex scenarios could be the key to decrypting its unexpected characteristics. Exciting times ahead!”
Facilities such as Ligo in the USA, Jungfrau in Italy and Kagra in Japan are constructed in such a way that they recognize the smallest distortions in space -time through violent cosmic events such as black hole fusions.
The fourth observation run began in May 2023, and the data is to be published later this summer by January 2024.
“This event leads our functions for instruments and data analyzes to the edge of the currently possible border,” says Dr. Sophie Bini, postdoctoral at CalTech.
“It is a powerful example of how much we can learn from the gravitational wave astronomy-and how much more there is to uncover.”
GW231123 is to be held together as a GR-AMALDI meeting in Glasgow at the 24th International Conference for General Relativity and Gravitation (GR24) and the 16th Edoardo Amaldi Conference on gravitational waves from July 14th to 18th.
