Two black holes, each of which is larger than 100 floors of the Sun, began to turn into the orbit of each other billions of years ago, and eventually collided and formed a new black hole with a mass of approximately 265 times the Sun. The collision took place about 10 billion light years from Earth.
The gravitational waves were recorded at the same time at the laser entrepreneurial gravitational wave observation (LIGO) stations in Washington and Louisiana states of Washington and Louisiana on 23 November 2023.
The signal was perceived only for one period of salice, and the united black holes caught the damping phase called “ringing ..
President of the Institute of Gravity Research at the University of Cardiff “These are the most violent events we can observe in the universe, but when they reach Earth, they turn into the weakest signals we can measure.”
Unusual black hole masses
According to The Guardian; The analyzes showed that the united black holes were in the mass of 103 and 137, respectively and returned 400 thousand times faster than Earth.
These values coincide with a mass range in which the formation of black holes is not expected. Hannam, “There are many reasons to think that black holes should not occur in this mass range,” he expressed his astonishment.
According to physicists, these extraordinary black holes are probably the product of other combines that have probably realized.
The rotation moment, which emerged during the black hole combinations, is transferred to the newly formed black hole. “We’ve seen some signs about it before, but this may be the extreme example, Han Hannam said.
Gravitational waves change our view of the universe
Until the 1990s, scientists could only observe the universe through electromagnetic radiation – visible light, infrared and radio waves.
Thanks to the gravitational wave observations such as LIGO, events that cannot be seen with light can now be detected.
Approximately 300 black holes have been detected so far. The largest merger observed before, resulted in a black hole with a mass of 140 times the Sun. This last collision doubled the record, reaching 265 sun mass. The findings will be presented at the Gr-Amaldi conference held in Glasgow, Scotland today.
Prof. “In science, you usually discover unexpected things when you start to look at the universe with a different eye, and all your perspective changes,” Hannam said. “New detectors to be built in the next 10–15 years, we will be able to see all the black hole mergers in the universe, and maybe we will encounter surprises that we never imagined.”
