The universe is vast and vast, composed of countless galaxies, and each galaxy is composed of a large number of various celestial bodies. Although the number of celestial bodies in the universe is too large to be counted, there are not many types. The more common ones are stars and planets.
Stars are the earliest celestial bodies born in the universe. They can generate light and heat and bring some light and warmth to the universe. Of course, the role of stars is much more than just illuminating and heating. It also plays an important role in the universe’s refining and chemical plants.
We must know that the original universe had only basic elements such as hydrogen and helium. How did hydrogen evolve into other heavy elements? At this time, the important role of the star comes on the scene. Through internal nuclear fusion, it continuously evolves the hydrogen element into heavier elements such as oxygen and iron. The life span of a star is limited. The greater the mass, the shorter the life span. When the star reaches its end, the interior collapses and the exterior expands, so a supernova explosion occurs.
The explosion of stars at the end of life can not only evolve more important cosmic elements, but also transform them into other special celestial bodies, such as white dwarfs, neutron stars, and black holes. For white dwarfs and neutron stars, we can observe more detailed information through astronomical telescopes, but we know very little about such extremely powerful celestial bodies as black holes.
The powerful gravitational force of a black hole can not only swallow stars, planets and other celestial bodies, but even photons with speeds up to the speed of light can also let them in or out. As long as the photon enters the black hole horizon, it will not come out again, but will be swallowed by the black hole. It is precisely because of the powerful swallowing ability of the black hole that our telescope cannot observe the true face of this celestial body.
Although the powerful swallowing power of a black hole makes it the most domineering celestial body in the universe, this domineering exposure reaches a certain level, which will form an event horizon and expose its existence. When a black hole swallows matter such as stars, it will form an accretion disk around itself. The dust fragments inside the accretion disk continue to rub, generating powerful energy radiation.
The energy radiation of the accretion disk will diffuse into the universe, which gives us hope to see that as long as we discover the huge energy radiation emitted by this accretion disk, we can be sure that there is a massive black hole there. The number of black holes in the universe is also too large to be counted. There is basically a supermassive black hole in the center of every large galaxy like the Milky Way.
The gravity of a supermassive black hole is too strong, and a huge galaxy structure will slowly form where it exists. The Milky Way, Andromeda Galaxy and other large galaxies were born because of a massive black hole in the center. The black hole in the center has also become the key to maintaining the stability of the entire galaxy. Under its strong gravitational force, the star system in the entire galaxy can maintain stable operation.
In fact, the role of massive black holes is somewhat similar to that of stars. The solar system has a star, the sun, and eight planets orbit around it, forming a stable solar system. As long as the sun does not undergo major changes, the entire solar system will not collapse and can continue to operate stably.
The same is true of the Milky Way. All star systems move around the galactic center, which is actually orbiting around this supermassive black hole. As long as this black hole does not have a major situation, then the Milky Way will not have major disturbances, and the solar system will continue to exist. But there is no absolute thing in this world. The life of the sun is also limited. After 5 billion years, the sun will expand and a supernova will erupt, and the entire solar system will usher in chaos and turbulence.
The expansion of the sun will engulf the earth. Even if we can move the earth’s orbit outward a little, the entire solar system is in a state of chaos. If the earth wants to exist, it can only leave the solar system. This is the terrible consequence of the end of the sun’s life span for the entire solar system.
The star system will be in chaos due to the huge changes in the stars, so will the Milky Way also experience huge chaos and changes due to the large state of the black hole in the center? The answer is also yes. Some people may say that the black hole in the center of the Milky Way has been very calm and will not undergo major changes. This worry is completely unnecessary. Is it really the case?
I believe everyone knows that black holes are relatively tough, especially supermassive black holes, which have a very grumpy temper. However, this massive black hole in the center of the Milky Way is 26,000 light-years away from the solar system and its mass is 4 million times the mass of the sun. Such a powerful black hole appears to be somewhat gentle. You must know that with the powerful phagocytic ability of a massive black hole, its accretion disk is extremely bright, even if it is tens of millions of light years apart, we can still observe it.
The galactic center is only 26,000 light-years away. As long as the black hole at the galactic center behaves more strongly, we can easily get more data about the black hole. It is a pity that this black hole was too quiet in the past. Although there is an accretion disk, it is not bright, and our observational understanding of it is very scarce.
It is because it is too quiet and too inactive, so the first photo of a black hole by mankind is not it, but a supermassive black hole 55 million light-years away from us, with a mass about 6.5 billion times the sun. For such a distant black hole, because it is too active, the energy released by the accretion disk is very powerful, so we also successfully took a picture of it.
Of course, from the perspective of human survival, we don’t want a bad temper, too active black hole in the silver heart. On the contrary, a relatively quiet and gentle black hole only needs to provide strong gravitation, which is our better choice. Therefore, we should be grateful that the black hole in the center of the galaxy is a gentle and good girl.
However, no matter how gentle the child is, there will be changes, and the black hole in the center of the galaxy has a situation. According to the latest observational data of astronomers, the black hole in the center of the galaxy has begun to wake up, and the huge swallowing power is more than three times that of the previous one. This is not good news.
The awakening of the galactic black hole is indeed not good news for the Milky Way, and more people are concerned about whether it will affect the survival of mankind? Some people may think that this black hole is 26,000 light-years away from us, which is very far away. After it wakes up, it will not have much impact on the solar system and the earth. Will it really be the case?
We must understand that behind all the order of the universe is gravity at work. The black hole is undoubtedly the overlord of the gravitational celestial body, and its swallowing power is so powerful that it makes the universe afraid. In the early stage of the awakening of the silver-hearted black hole, its swallowing power has been increased three times, and no one can be sure that its awakening is only temporary or will become stronger.
If its phagocytic power continues to increase and eventually becomes a fully active massive black hole, then it will first swallow a large number of stars around the galactic center. You must know that more than half of the stars in the entire galaxy are concentrated near the galactic center. Once these stars are swallowed by black holes, the galaxy structure of the Milky Way will inevitably appear in a big chaos.
Although the solar system is 26,000 light-years away from the Galactic Center, it is a relatively remote location. However, the entire galaxy system is in chaos, and the solar system cannot be left alone. The most serious consequence predicted by scientists is that the entire silver system may eventually be completely swallowed by this black hole and become a cosmic void.
You know, scientists have discovered through a large number of starry sky observations that there are many holes in the universe, some of which can reach hundreds of millions of light-years in diameter. How are these holes formed? Scientists speculate that it may be caused by the continuous engulfing and fusion of black holes.
If the solar system is unable to take care of itself, it will also usher in a huge disaster, then the earth will naturally not be immune. When that day comes, the only way for mankind is to leave the Milky Way to live in other galaxies. Of course, to achieve this goal, we need to master space tracking or wormhole technology. Otherwise, within the scope of the Milky Way, we don’t have it. Way to leave.
Of course, scientists have only observed the awakening of the silver-hearted black hole and found that its swallowing power has become more than three times stronger. As for whether it will continue to become active in the future, there is no conclusion yet. Only by collecting data through continuous observation can we know how it will evolve in the future.
Even if the growing trend of the galactic black hole cannot be changed, we do not need to worry too much. This is an extremely long period of time, which may be millions of years, tens of millions of years, or even hundreds of millions of years. In such a long time, with the development speed of human technology, it may have become a powerful interstellar civilization. At that time, humans will not only cross the Milky Way, but also have our presence in other large galaxies. Even if the Milky Way cannot survive a catastrophe, we can abandon the Milky Way and move to other galaxies.
