For Black holes, A collision should not be a one-time experience of a lifetime, new research suggests.
On April 12, 2019, scientists discovered a new black-hole merger using a trio of gravity-wave detectors. Astronomers had previously discovered such phenomena, but this time there was something different about the signs: there were two colliding black holes. Incredibly unequal matches, With three times the size of the smallest. Scientists did not expect such an unbalanced merger between black holes, and now, they think they can understand the unusual phenomenon.
“This event is a dubbed ball that the universe has thrown at us,” said a physicist at the Massachusetts Institute of Technology and author on new research. Said in a statement. “But nothing happens in the universe just once. And something like that, though rare, we’ll see again, and we’ll be able to say more about the universe.”

Vital and his colleagues suspect that a bizarre collision after a large black hole was the product of a black-hole merger. The initial incident sent a huge black hole around which there was a surge in people around Packed with black holes, This hypothesis runs, enabling unequal collisions.
It’s a very different story than the two main scenarios of the scientists for the black-hole merger, which also gives a fair boost to both matches. Vitaly and his colleagues used two different models to evaluate whether conventional merger conditions could create an event similar to an unbalanced merger. No aspect.
“What we do, we can’t easily build this event into these more common creation channels,” Vitaly said.
So the team turned to a process called hierarchical merging, in which the result of a black-hole merger continues to merge again. And this time, the M models dello seems meaningful. Vital said, “You do the math, and it turns out that the remaining black holes will have a spin that is very close to the total spin of this merger.”
Coincidentally, gravitational wave researchers published other research this week that also points to merging hierarchies. On Wednesday (Sept. 2), the scientists behind the gravitational-wave detectors LIGO (short for “Laser Interferometer Gravity-Wave Observatory”) and Virgo announced that in May 2019, they will have a The black hole that was big How stars are formed by explosions rather than scientists. The suspicion is that this large black hole, if not both of the original members of the event, was the result of a previous merger.
Scientists behind the new paper analyzing unequal collisions suspect that the hierarchical merger may not just take place anywhere, but should be in a relatively close neighborhood, where black holes can easily communicate with each other.
“This merger should come from an unusual place,” Vital said. “As Lego and Virgo continue to explore new things, we can use these discoveries to learn new things about the universe.”
The research is described A paper Physical Review Letters Journal 2 Sept.
