Physos find the biggest combination of collision with black holes. Discover has major implications for understanding researchers how the bodies of the universe is progressing.
“This is the most interesting,” says Priyamvada Natarajan, a theoretical astrophysicist at Yale University in New Hindn, Connecticut, which is not involved in research. Combining between black holes with mass greater for physicists to easily explain. “We saw it forbidden black black holes,” he said.
The discovery is made of Laser interferometer gravitational-wave observatory (Ligo), a facility involving two US detectors. It will come at a time when US funding for gravitational-wave detection is facing with broken cuts. The results, released As a preprint of Arxiv series1presented to GR-AMALDI Gravitational-waves meetings in Glasgow, UK, 14 July.

Prohibited mass
Ligo knows gravitational waves by firing lasers in height, l-shaped arms. Minuscule changes at arm’s length reveals throwing gravitational waves on the planet. The waves are cut into space-time, because of the many bodies facilitates, such as if two striking black holes or neutron stars fit.
Hundreds of equations were observed using gravitational waves since Ligo’s first detection in 2015. But this most recent detection, made on November 2023, is the greatest. By modeling the signal found by Ligo, scientists have been calculated that activity, called GW2311123, due to two black holes with a final hole weight of about 225 solar mass.
“This is the greatest (mergers) so far,” says Mark Hannam, a physical constant lvk gravitations detectors Ligo, Virgo in Italy and Kagra in Japan. It’s “about 50% more than the previous record holder”, he said.
Most events that Ligo gets involved in stellar masses of black holes – those from several to 100 times the masses of the day – which thinks their lives as supernovae. However, both black holes involved in GW231123 fall into or near a predicted range, with 60-130 solar masses, that this process is not expected that the stars should be removed. “So they may not be formed by normal mechanism,” Hannam said.
However, both black holes are likely to be formed from the first events of union – hierarchical mergers of many bodies found in the bath, which is estimated to have occurred in the bath, which is estimated with 0.7 to 4.1 billion years of light).
It is like “four grandparents who combine two parents
Models of black holes also suggest that they raise easy – about 40 times per second, close the general theory of relativity in black holes. “They entered very close to the highest storage allowed,” Weinstein said.
It is the same as waste and the masses can signs on how black holes in the universe is growing. One of the largest astronomical questions is how the largest black holes, found supermussive black holes in galaxies like the milky way, growing in the first cosmos.
Even if there is a lot of evidence for the existence of stellar masses of black holes and supermssive black holes – those more than a million mass of solar – Intermediate masses of black holes In the range of 100 to 100,000 solar masses are more difficult to find. “We couldn’t see them,” says Natarajan.
The most recent detection can tell us that “these intermediate black holes in some hundred masses of solar, maybe by hierarchical clears, may also be hierarchical cleans, may also increase the hierarchical galaxies, maybe in the hierarchical hierarchical clears, mahimo usab nga madugangan ang mga hiernam sa mga galaksiya, nga tingali ang Misa, ingon usab ang mga hierarchical mergers, tingali pinaagi sa mga hierarchical clear, mahimo usab nga madugangan ang mga hierarchical sa mga galaksiya, mahimo usab nga madugangan ang mga hierarchical sa mga galaksiya, nga tingali ang Misa, mahimo usab ang Misa, sa mga mirm, sa mga messengling nga itom. “Just slow, we build a list of the kind of black holes that are there,” he said.
Cluts forward
That development of knowledge can be prevented from the US Donald Trump president and the proposed cutting of the US National Science Foundation, which runs ligo. Under the proposal, one of two gravitational-wave observations in the bath close.
At the time of this seeing November 2023, Virgo and Kagra did not operate. Without the two detectors, uncertain scientists make them a true detection of two united black holes, as Hannam. “Because we had two detectors, we saw the same blips at the same time,” he said.
The closure of one of the observators can be “catastrophic”, says Natarajan. “It can’t be discovered if an arm is killed.”
Planned to upgrade to the bath in the coming years, and the addition of new detectors around the world, including one in IndiaIt may increase the capabilities of the physicist of the gravitational-wave research, an astronomical area still in its youth.
“We can see thousands of black holes in the next few years,” Hannam said. “It has a great investment that has been done, and it just starts to pay.”
