Surprising collisions could be the result of a chain reaction of collisions, the researchers say.
About seven billion years ago, two monster black holes of such magnitude spread simultaneously in a catastrophic space invasion, shooting the pulse of gravitational waves across the universe. Surprisingly, those gravitational waves arrived on Earth just over a year ago, and astronomers now believe they have discovered the most powerful black hole collision ever: an event that dubbed GW190521.
🌌 You love our Bedas universe. So we do. Let’s explore it together.
U.S. In May 2019, researchers at the Laser Interferometer Gravitational-Wave Observatory (LIGO) and the Coorg Observatory in Italy first discovered ripples in the wave space-time fabric in May 2019. And 66 and times 85 times larger than our Sun, astronomers reported in two papers published last week. Physical Review Letters And Astrophysical Journal. When they collided, they formed a black hole about 142 times larger than our Sun.
Not only is this potentially the most powerful eruption recorded, but it also proves the existence of a rare class of black holes: the intermediate-mass black hole. “Now we can dispose of the case and say that intermediate-mass black holes exist,” said Christopher Barry, a ligo astrophysicist at Northwestern University. National Geographic.
Theoretically our sun should not have a black hole 85 times larger. Theories about how those stars die do not resonate well with researchers. Stars that normally burn all of their fuel from a few times to 60 times the mass of our sun and eventually fall on themselves, creating a “conventional” black hole.
Stars that are about 60 to 130 times larger than our Sun, but they do not usually form black holes. Instead, they form something called a pair-instability supernova. Is the heat that comes during the compression of the star So Powerful, out-of-the-box content is destroyed. According to current theory, it cannot simply be a black hole. (Like the supermassive black hole photographed in the middle of the M85, our sun is numbered from the stars to the billions.)
Daniel Holz, a member of the LIGO team, a theorist at the University of Chicago, said Jemmy’s discovery was both disappointing and exciting. New York Times. “On the one hand, one of our favorite beliefs has been proven wrong. On the other hand, there’s something new and unexpected here, and now there’s a race going on to try to figure out what’s going on.”
So how did this huge collision come about? Some researchers suggested to black holes that they were primitive surrounded by each other, meaning that they lived shortly after the Big Bang and follow their own set of global guidelines. The second theory suggests that these mysterious intermediate-mass black holes formed from a black hole merger that formed earlier.
For this view to work, location is the key. When black holes collide, the gravitational waves they produce repel them, pushing them out of their galaxy. But to meet these two large black holes, the galaxy in which their previous collision occurred must be incredibly crowded and have a gravity bridge to keep the black holes relatively close.
Astronomers are not sure where the massive collision occurred. There is a key. In June, researchers at the Zwicky Transient Observatory in California discovered about a quarter of the flames in the same sky. This bright flash may be the result of a shockwave produced by a black hole designed during the GW190521 event. But more needs to be done to link these two events.
In any case, this is a waterless moment in astrophysics. Discoveries at the King’s Observatory and the LIGO, Washington twin observatories in Washington, D.C., and Louisiana, respectively, reshaped our understanding of the universe, and researchers there received the Nobel Prize. The work on these observations has allowed astronomers to gradually unravel the most mysterious mysteries of our universe. They are not finished yet.
