Scientists have found a supermassive black hole, 290 million light-years away from the earth, spinning at 50% of the speed of light

The universe is vast, in addition to our common stars, planets, neutron stars and other celestial bodies, there are some special objects without entity, such as black holes. Black hole can be said to be the most special and mysterious celestial body in the universe. Scientists still don’t know what a black hole is. They only know that its gravity is super strong and can devour any matter.

Modern science believes that black holes are evolved from the death of massive stars, and the center of black holes may be a singularity with infinitesimal size and super large mass. Its super large mass brings huge gravity and forms the event horizon of black holes around it. This singularity may also rotate at a high speed, and the range of the event horizon driven by it is also rotating at a high speed, and any person who enters the event horizon will enter the event horizon All the surrounding material will be swallowed, including stars.

According to the different mass, black holes can be divided into stellar black holes, galaxies and black holes. Stellar polar black holes are common black holes and exist more in the universe. Their horizons are generally not large. However, we should not underestimate such black holes. Although they are small, their power is not weak at all. It is possible to devour stars, but it takes a long time.

Galaxy level black hole is what we call supermassive black hole. For example, a * in Sagittarius, the center of the galaxy, is a galaxy level black hole. Its horizon is very large. The strong gravity can affect the whole galaxy. Supermassive black holes in the universe are much less than stellar black holes. They are basically galactic centers like the Milky way, which manage the operation of the whole galaxy with super strong gravity.

Black holes are basically in high-speed motion, and the rotation speed is not too exaggerated. However, some time ago, scientists discovered an unimaginable supermassive black hole. The reason why it surprised scientists is not because of its mass, but because its rotation speed is too fast, at least 50% of the speed of light.

It’s incredible to see a black hole rotating at more than half the speed of light. You know, although the black hole does rotate at a high speed, the rotation speed can’t be compared with the speed of light. The faster rotating objects in the universe belong to pulsars. Pulsars are the fastest rotating objects discovered by human beings. They generally rotate at a high speed, but there are no pulsars with the fastest rotation It’s 50 percent light speed.

This huge black hole is 290 million light-years away from the earth, and its horizon is about 300 times larger than that of the earth. In such a wide range, it takes only two minutes for the earth to rotate one cycle, while it takes 24 hours for the earth to rotate one cycle. The faster the rotation speed of a black hole, the stronger its gravity may be. This supermassive black hole may have much stronger gravity than other black holes of the same mass.

So how did scientists discover this huge black hole? You know, black holes are special mysterious tianxiuyi, they have no entity, plus super phagocytic power, even light, so we can’t directly observe black holes. Only when a black hole devours a huge celestial body, can it be observed through the energy emitted by the tearing of the celestial body.

This supermassive black hole, 290 million light-years away from the earth, can be found by human observation equipment. The main reason is that it tears a star close to it. When the star decomposes, it emits bright energy light. After a long journey, the energy wave radiation reaches the solar system and is discovered by optical telescopes. Therefore, the black hole scenario we are observing now is actually a black hole 290 million years ago. It is not known what it will become now.

The mass of this supermassive black hole is 0-10 million times that of the sun, similar to that of Sagittarius A * in the center of the galaxy. However, because the black hole rotates too fast, far faster than the black hole in the center of the galaxy, its gravity may be much stronger than that of Sagittarius A *. Using NASA’s Chandra and Hubble space telescopes and other instruments, scientists have studied the supermassive black hole system of asassn-14li and determined the spin rate of the black hole, which is a basic property that astronomers have been difficult to measure.

This kind of rotation speed is impressive, but it is not the only one in the universe. There are still black holes in the universe with rotation speed of more than 33% of the speed of light, but it is relatively rare. Some black holes can rotate more than 80% of the speed of light. As for whether there are black holes with rotation speed of more than the speed of light in the universe, it is not known.

The universe is so big that there are all kinds of strange things. There are only things that we can’t think of. There is no universe that doesn’t exist. Compared with the vastness of the universe, human beings have too little knowledge of the universe. Our rapid development of science is only about a hundred years old. It’s amazing to have the present achievements. It is believed that with the rapid development of human science and technology, we will know more about the universe and black holes in a few hundred or several thousand years.

At present, the research on black holes is still in the stage of exploration and conjecture, and there is no final conclusion on what is the essence of black holes. They are still in the exploratory stage. To really understand the nature of black holes, we may need to get close to them or even go deep into them, but this kind of thing is far beyond our imagination. You know, these supermassive black holes are very far away from us.

The black hole in the center of the galaxy nearest to the earth is 26000 light-years, and it will take 26000 years for a spaceship to fly at the speed of light. Therefore, if we want to get close to such a black hole, the speed of the spaceship must reach the speed of super light, and if we want to go deep into the black hole, we need to develop the technology that can counteract the gravity of the black hole. For human beings, it will take a long time, which may be thousands of years or tens of thousands of years.
