There are numerous celestial bodies in the vast universe, and these celestial bodies are mainly stars and planets, which can be said to be the mainstream of celestial bodies in the universe. Under the mainstream objects, there are also some non mainstream special objects, such as neutron stars, pulsars, black holes and so on.
The non mainstream celestial bodies are often the most mysterious and powerful group in the universe, and the leader of this group is the black hole. No celestial body can be stronger than the black hole. At least in the current space exploration of human beings, no more powerful celestial body has been found than the black hole. It can be called the overlord of the universe. Even stars are the food of black holes. Even photons flying at the speed of light can hardly escape once they enter the horizon of black holes.
It is because of the powerful phagocytic ability of black holes, even light does not let go, so it is difficult for us to directly observe the existence of black holes through the reflection of light. However, the powerful phagocytic ability of black holes is often difficult to really hide themselves, especially supermassive black holes. Their phagocytic ability is extremely strong. It is as easy to phagocytize stars as drinking water. In the process of phagocytizing stars, the resistance of stars will burst out a strong flash.
We can determine the existence of supermassive black holes by the presence of these flashes, which are bright accretion disks. Of course, for those small and medium-sized black holes, we can hardly observe them. They have no obvious accretion disk, and the flash is very weak. Unless they are very close to us, generally, we can’t find small and medium-sized black holes.
With the current scientific and technological strength of human beings, only supermassive black holes can be observed and discovered. Sagittarius A * in the center of the Milky Way galaxy is a supermassive black hole with a mass about 4 million times that of the sun. However, the supermassive black hole in the center of the galaxy is a relatively gentle existence in the supermassive black hole family of the universe.
Some supermassive black holes, whose mass can reach tens of billions of times that of the sun, are really terrible cosmic black holes. One of the most interesting objects for scientists to explore and observe the starry sky is supermassive black hole, which is the most mysterious and powerful object in the universe. If we can study the mystery of black hole, we may be able to uncover many mysteries of the universe, even the origin of the universe and some ultimate Mysteries are related to black hole.
Another powerful attribute of black holes is crazy rotation. Different black holes rotate at different speeds, and some even reach 99% of the speed of light. On November 22, 2014, scientists observed a mysterious flash from the depths of the universe. According to analysis, the flash originated from the tidal tearing event of a supermassive black hole (about 1 million times the mass of the sun) in the center of a galaxy 300 million light-years away.
Tidal tearing event refers to the process of the black hole devouring stars. When the stars enter the horizon of the black hole, they will be torn up by the strong tidal force, and then they will continue to devour and become the food of the black hole. Before a black hole feeds, it often forms an accretion disk around it. The stellar matter in the accretion disk will explode amazing flash because of being heated to ultra-high temperature, which is called tidal tearing flare.
The researchers found that this tidal tearing event is a good research sample, which is consistent with many theoretical predictions. Moreover, the X-ray bursts will take 131 seconds as a cycle and last for 450 days. It’s amazing that, according to their calculations, this supermassive black hole is spinning at 50% of the speed of light.
Although this speed is not the fastest in the family of supermassive black holes, it is already an incredible speed. The black hole in the center of the Milky Way galaxy is not as fast as this black hole, so the black hole in the silver center is very gentle. I believe many friends understand a truth, when an object or celestial body speed is higher and higher, it will also produce a very terrible gravity.
The reason why black holes are terrible is that they have very strong phagocytic power. In addition to their strong mass, there is also a very important factor, that is, they have super fast speed. According to Einstein’s theory of relativity, as the speed of an object continues to increase, time will continue to slow down. If the speed of an object is infinitely close to the speed of light, then time is infinitely close to stop.
From this, we can draw a conclusion that the space-time around the black hole is in a distorted state, not only the distortion of space, but also the distortion of time. If so, the black hole can also be regarded as a time machine, but this time machine can not go back to the past, only to the future. Maybe someone will say, how is that possible?
In fact, the ability of a black hole to travel through space-time depends on its extremely high speed, which is infinitely close to the speed of light. Imagine what would happen if our spaceship could ignore the gravity of the black hole and enter the black hole? At this time, the spacecraft may also rotate at a very high speed with the black hole, which may be infinitely close to the speed of light.
If the speed of the spaceship is infinitely close to the speed of light, then time will be infinitely close to stop. At this time, no matter how long the outside time has passed, for us inside the spaceship, it is just a moment. When the spaceship leaves the black hole and we return to the earth, the earth may have passed hundreds, thousands or even tens of thousands of years, that is to say, we have passed into the future.
Even if the rotation speed of the black hole is only 50% of the speed of light, our spaceship moving around the black hole at 50% of the speed of light will also slow down the time. When we return to the earth, we will also find that we have come to the earth in the future. Of course, a black hole can only let us go to the future, but it can’t let us return. Strictly speaking, it’s not a real time machine. It’s just that its ultra-high speed affects space-time and makes space-time distorted, and things in this distorted space-time will also slow down.
Scientists have seen the attribute of black hole as a super-high speed, so some scientists have put forward the idea of using black hole to go to the future. Of course, the idea is beautiful, but it’s not so easy to realize. We need to know that the super gravity of black hole can tear everything, and our spaceship can’t bear the pull of the gravity of black hole.
Even if material technology is more powerful in the future, it may not be able to resist the gravitational pull of the black hole. Therefore, if you want to enter the black hole and go to the future, it is important to have gravitational counteraction technology. In other words, through the power of science and technology, to hedge the gravity of the black hole, so that the spacecraft into which can be in a stable state.
This kind of technology seems incredible. In fact, it is also an application of gravity. I believe that with the rapid development of human science and technology, this kind of technology will be realized in the future. At that time, we can enter the supermassive black hole and go to the future in the distorted space-time. Of course, it’s a one-way journey. You can’t come back if you go.
In fact, our current understanding of black holes is very small. We can’t observe small and medium-sized black holes, so we can’t study them. And supermassive black holes are very far away from us. Even the nearest black hole in the center of the galaxy is 26000 light-years away from us. To reach the center of the galaxy, we need to achieve superluminal flight, but for human technology, it will take us many years to achieve subluminal flight.
Superluminal flight can be said to have subverted the existing physical system. Only when our basic physics can be subverted can we hope to explore and study the superluminal flight technology, which is also the key to future interstellar navigation. Without superluminal technology, we can’t even travel across the galaxy, let alone explore the universe.
