What’s at the center of a black hole? Scientists have a sobering answer.
They are science fiction, science paradox and probably the key to understanding the universe.
Scientists have been trying to understand the mysterious powers of black holes for decades, but so far seems to have found more existential questions than answers.
In Priyamvada, a theoretical astrophysicist at Yale University, Natarajan, we know that a black hole is so heavy that it creates a kind of divot in the geometry of the gravity universe.
“A black hole is so intense that space/time causes a bit deep drilling. At the end of the madman, there is something called singularity in which all known nature laws are disintegrated. There is nothing we know at this point.”
Understanding what science knows about black holes, mysterious little red spots, the formation of galaxies and the spAGETIFICATION (unpleasant thought experiment on what will happen to a unlucky enough to be drawn to the black hole).
First, good news: Black holes are not outside to get us. They do not whisper around the universe looking for galaxies, suns and planets for dinner.
Davis, Professor of Physics and Astronomy at the University of California, Lloyd Knox, said, “They are not only hidden in a dark street,” he said.
However, our understanding of the many foundations of the universe has been transformed by new telescopes and sensors that allow scientists to see more black holes and their lives in the last decade.
Natarajan said, “We understand the role of black holes, they are an important part of the formation of galaxies,” he said.
Which cosmic secrets emerge here:
This picture shows a flow of material shining from a star because it is swallowed by a super -mass black hole. When a star passes through a certain distance of a black hole – close enough to deteriorate as gravity – the star material is stretched and compressed as it falls into the black hole.
A new kind of black hole and a new proven theory
The original understanding of how black holes occur is that when a large enough sun (about 10 times or larger than our sun) reaches the end of his life, he can then explode a supernova that falls into a black hole. The problem can collapse for something for just a few miles, become so intense, gravity is too strong to escape anything that is not even lightweight. Star mass is called black hole.
However, in the last twenty years, new types of black holes have been seen and astronomers are starting to understand how they were formed. Named Super Mass Black HoleThey were in the center of almost every galaxy and the mass of our sun is one hundred thousand to billion times.
But how did they create?
“The original idea was the formation of small black holes and then they grew up.” He said. “But then there is a timing crisis to explain the monsters in the early universe. Even if they were pulling the star gas down, they had time to grow so much? This was an open question even 20 years ago.”
In 2017, from the early beginning of the universe, these super -mass black holes, when the galactic gas clouds collapsed directly to themselves, when the star completely jumped the stage, and directly from the gas to a large black hole seed, then can grow later.
“Then guess what happened? James Webb Telescope in 2023 I found these objects,“He said.” To make a guess and see that a scientist lives. “
These composite images were shown side by side with two different clusters of galaxies with a central black hole, each surrounded by patches and gas filaments. The galaxy clusters, known as Perseus and Centaurus, are two of the seven clusters observed as part of an international study by Santiago de Chile University.
Black holes do not suck everything
Since they have such a large gravity, black holes are forcing star gases and something that approaches them very much. But it is not an endless process that results in the absorption of the whole universe.
People are sometimes worried that black holes are these large vacuum cleaners that draw everything visible. “Not like a jacuzzi that drives everything into everything,” Knox said.
Black holes are like other mass concentrations, whether the sun or planet. They have their own gravity, but not endless.
“If you are just far away, you’ll feel from a planet, just if you feel from a planet,” Brenna Mockler, a post -doctoral man at Carnegie observations at the Carnegie Institute of Carnegie in California. He said.
This image shows the location of the newly discovered binary star D9, which rotates Sagittarius A*, the super -mass black hole in the center of our galaxy. The first star pair near a super -mass black hole.
If you fall into a black hole, ‘you will be spagnetized’
Natarajan said that all substances caused a diving or pit in space/time. A black hole is so heavy that gravity creates a kind of divot in the geometry of the universe.
“The larger the mass, the greater the pit,” he said. “At the end of the explosion, there is something called singularity in which all known nature laws are broken. There is nothing we know at this point.”
These puncture tips are unknown.
“This is a clear question,” Natarajan said. “We don’t think this might be another universe, because we don’t know where to go in our universe. But we don’t know.”
What if a person falls into the black hole? Astrophysicists have a word for this – spAGETIFICATION.
Natarajan said, “If you were going to fall into a black hole, it would be intense enough to be different, extended and spagnetized in gravity between your head and toes.” He said.
Our sun will never be a black hole
Knox is not afraid that our own sun will be a black hole. Not big enough.
“Lower mass stars burn their hydrogen to make helium and then begin to burn the helium into the carbon. And then it only separates itself at some point.” He said.
“Our sun will end and wrap the world at the end and destroy – but in 5 billion years, so you have some time to prepare. But there will be no black holes.”
A mystery still unanswered – ‘Little Red Points’
NASA’s super -powerful James Webb Space Telescope started its scientific mission in 2022 and received almost something that no one could explain: small red objects that look plenty of cosmoda.
Dubbing “Small red dots“These objects have astronomers. Very intense, highly star galaxies.
Davis, a professor who came at the University of California, Mockler, “Or very early universe collected super -mass black holes can be.” He said.
