There was a collision of two black holes in space.
Never before has a human being been able to observe such a process.
Pasadena - Black holes pose a mystery to science (*Merkur.de reported).
How are they created?
What is hidden inside?
Science has been searching for answers to these questions for decades.
Now researchers have been able to observe something that has never been observed by humans before: the collision of two black holes, whose collision was so violent that it released unimaginable energy into space.
“It is the largest bang that mankind has ever observed since the Big Bang,” Alan Weinstein, an astronomer at the California Institute of Technology, told US magazine Popular Science.
He was part of the team that discovered the colliding black holes.
The scientist hopes that his discovery will provide clues as to why the universe looks the way it does.
Merger of two black holes
The black hole collision occurred at a distance of around seven billion light years from Earth.
The two massive celestial objects merged to form a new black hole.
The energy released was so enormous that it caused a disruption in the cosmos.
This is the first sighting of a medium-sized black hole formed by a merger.
It is 142 times larger than the Sun.
The results of the discovery were published in Physical Review Journals.
The fusion signal from the collision only lasted a tenth of a second
The effects of the collision can also be detected here on Earth.
Because: The space-time continuum expanded due to the released energy, collapsed and vibrated, creating gravitational waves that measurably reached our home planet on May 21, 2019.
There is no photo of this newly created black hole*.
The researchers were able to determine the noise.
The signal, called “GW190521,” lasted only a tenth of a second and was unexpected for the researchers.
It was only in 2015 that a similar signal was measured from the collision of two other black holes.
However, compared to its sound, which resembled a deep chirping, the new noise was higher pitched.
Two black holes combine to form a gigantic black hole
What was also new for the scientists was that the heavier of the two colliding black holes was in the so-called “pair instability” and still had a mass of 85 suns.
However, according to Alan Weinstein, a star that collapses “should not be able to create a black hole in the range of 65 to 120 solar masses.”

The reason for this is “that the most massive stars are wiped out by the supernova that accompanies the collapse.”
The astronomer still has a possible explanation for the phenomenon, which is related to the theory of so-called hierarchical mergers.
According to them, light black holes initially merge with the star mass.
Editor's note: This text has already appeared in the past. Many readers were particularly interested in it. That's why we're offering it again.
“They consolidate until they become gigantic black holes,” says Alan Weinstein, who is excited about future observations: “We need to look for more exotic events like this.
And after exotic events the likes of which we have never seen before.
Wouldn’t that be great?”
