Black hole is colliding with ‘ringing’ throughout the space and time, Hawking proves to be correct
Once again, it turned out that the famous theoretical physicist Stephen Hawking was correct. Oh, and Albert Einstein too.
Scientists of the US National Science Foundation’s laser interferometer gravity-wave observator (Ligo) detected a gravitational wave, a wave in space-time that is caused by highly energetic processes, such as two black holes or two thick neutron stars are merged.
It turns out that the gravitational wave occurred about 1.3 billion light years away from the earth due to two black holes, with about 30 times mass compared to our sun, colliding with another black hole and designation with GW250114.
It’s not uncommon Ligo detectorOne is located in Hanford, Wash, the other is Livingstone, La. In, which has been found to be close to 300 of these violent interactions. But this time, researchers were able to learn much more than before.
Predictions
The merger of these special black holes created what scientists referred to as “ringing”, which produced two different tones, allowing researchers to confirm that a black hole could be defined using only two properties: Mass and spin, something that was predicted by Roy Carr in 1963.
One of the co-writer of the study, Jess McIver said, “One of the unique qualities to a black hole is that … such as if you hit a tuning fork, it especially rings on the frequencies, and they will have specially vacancy,” Jess McMar said, Jes Mcivar said, one of the co -itrants of the study, one of the co -itractor of the study.
“It is like a fingerprint of a black hole. So because it was very loud, so grand, loud indication, we were really able to resolve those people.”
Max ISI, an assistant professor at Columbia University, and co-writer of the study, Journal published in physical review lettersExplained it more.
“There are two personal ways of oscillations, two tons: a fundamental tone and one overtone,” he said.
Because tons used to match, they say, this is proved to be a solution. If the tons were different, it would mean that other qualities are necessary to describe the black hole.
This proved both Kerr and Einstein right about their predictions for Black Hole. Einstein’s principle of general relativity predicted the existence of black holes. And in the case of Kerr, their calculation was particularly concentrated around the spinning of the black hole.
Hawking area theorem
The merger also confirmed the theory of Hawking, stating that when two black holes merge, the event horizon – or the area around the black hole, no light or radiation can survive – can never be reduced, only growth.
After the merger of two black holes, scientific phenomena were able to use ringing to determine the final size of the horizon – the surface area of ​​the black hole was also considered. Before the merger, each black hole had a surface area of ​​about 240,000 square kilometers. Subsequently, the new black hole had a surface area of ​​400,000 square kilometers, which proved Hawking right.
“I think for Hawking, Black Hole and Space and Time have been studied as theoretical mathematical essence for decades. And finally, being able to see these processes, you know, it’s surprising,” ISI said.
“I mean, it’s amazing to me, and I cannot imagine him, you know, doing our whole life on it. So it’s unfortunate that we could not do it while living.”
Now, when the surface area increased, the mass of the black hole actually decreased, which the principle suggests that.
“The area of ​​the phenomenon horizon, it can only grow,” said Janna Levin, a theoretical astronomer physicist and Professor of Astronomy at Bernard College, Columbia University, who was not involved in research.
“And if I was thinking of absorbing the other as an original black hole, it can only grow, but its mass is not the sum of two mass. It is actually low. It loses that E = MCR energy into gravity waves.”
Each black hole was about 33 times the mass of the sun. After the merger, the black hole had 63 times more mass of the sun.

Really away, but really loud
A similar analysis of almost identical black holes merger – long ago It was revealed in 2015 – Was done in 2021. However, it did not provide the same strong evidence that this new analysis did.
The ISI explained that because the signal for that black hole was weak, scientists were still quit to guess, but the signal for the recent merger was four times stronger.
He said, “You can see that 2021 paper as a performance that something will be possible in this way, like the proof of the principle,” He said, this merger was “real, incompatible” proof.
The 2015 detection of a gravitational wave received researchers to receive the Nobel Prize in Physics in 2017, as part of the Ligo-Virgo cooperation. Today, in Japan, there are more observatories that detect gravitational waves including one, which create Ligo-Virgo-Kagra cooperation.
Both MCIVER and ISI are excited that future improvements in detectors will help them find them.
The Mciver says that Einstein, Kerr and Hawking predicted, no matter to checking the signal to check the signal against it, it makes no difference to this data in different ways “
“As detectors continue to improve, our confidence will improve, or potentially we will reveal something really interesting that we are not expecting.”
