The concept of black hole and white hole, strictly speaking, is just a conjecture made by the scientific community. What people did not expect is that in 2019, the existence of black holes was successfully observed by humans, which also shows that all th

Objects at rest in the ergosphere of a rotating black hole travel faster than the speed of light. This sentence sounds quite contradictory: how can an object be both static and faster than the speed of light? In order to understand the real situation beh

As we all know, a black hole can devour everything around it with extremely strong gravitational force, even light cannot escape. And we also know that there is not only one black hole, but also many types. Today, let’s talk about the Schwarzschild black

Black holes have always been a mysterious existence, and no one has ever seen them. They only exist in science fiction films and Hawking's papers. The picture of the black hole we see is a sky area that can devour all planets, whose density and volume can

In the vast universe, all kinds of magical things are possible. Scientists have also been exploring the mysteries. The phenomenon of black holes swallowing stars that I told you today is also a spectacle in the universe. What will happen when black holes

Everyone has heard of black holes, because of the huge gravitational force, any matter that approaches a black hole will be swallowed up, and even light cannot escape. Previously, scientists have observed the whole process of the black hole eating the sun

What is a Kerr black hole? At first, like many netizens, I didn’t know it. Until a few days ago, I accidentally saw a report about a Kerr black hole a few years ago. The report said that a physicist from the University of Washington in the United States

In countless sci-fi films, the black hole is a mysterious existence. The black hole is actually the entrance to the universe and enters another dimension. A primary black hole is a hypothetical black hole that was created during the Big Bang. Unlike other

The mysterious existence of black holes has attracted countless astronomers. It is naturally impossible to reach outer space, so astronomers are looking for alternatives to various black holes. Man-made black holes are made through particle accelerators,

Vy Canis Major, once the largest planet in the universe, had a radius about 2,000 times the radius of the sun, but it was found that it has already reached the end of life. A large amount of mass is lost every year, and the mass is only 40 times that of t

We know that there are black holes, white holes and wormholes in the universe. So what are gray holes? In the past, Hawking was famous all over the world for proposing the theory of black holes, but later Hawking said that there are no real black holes in

According to reports, the United States discovered the largest black hole in the universe in observations. This is the largest and oldest black hole discovered so far, with a mass 18 billion times that of the sun. There is also a small black hole next to

The word black hole appears in various large-scale space adventure films, and many protagonists encounter black holes in the plots, which are close to death. People's understanding of black holes is estimated to be that it can swallow everything and even

As long as the cosmic stars are mentioned, I believe that many people will be excited. After all, this is something that our current technology can only see but cannot touch. However, in recent years, human technology is developing. With the rapid develop

Recently, a terrifying news about a black hole eating the sun has spread in the astronomy community. Many people don't know if the news is true or not? Do black holes really exist? Black holes have always been mysterious in everyone's cognition. It is sai

Black holes have always been unrecognized things before, that is, scientists actually confirmed their existence a few months ago. At that time, it was really hot on Weibo. Black holes were divided by scientists according to their properties. Three types,

The black hole has always been a very magical existence. So far, human beings have nothing to do with it. Although they are studying it every day, this behemoth is really difficult to study. It is rumored that the black hole is a door connecting two world

A giant black hole is a celestial body formed by the collapse of a star with a larger mass after its energy is exhausted. The maximum mass it can have is about 10 times that of the sun. Even black holes with billions of times the mass of the sun. At prese

For the first time, researchers have observed the precession effect of a star's orbit around a giant black hole, proving yet again that Einstein's theory of relativity is correct. An artist's impression of the precession of a star's orbit around the supe

We all know that the gravity of a black hole swallows everything, including light. But that's for objects right near the black hole, for the accretion disk right next to the black hole, where light can escape. Scientists have found that this is actually
