Chapter 19 The Destruction of Heaven and Earth 3
Amitabha continued: "For the first time, the Oriental Immortal photographed a spectacular scene of a massive black hole tearing and devouring stars and spewing out jets. This rare scene is one of the most intense phenomena in the world. This black hole, which can be called a 'space monster', is located in the middle of a distant galaxy, nearly 4 billion light-years away from Earth. After devouring the star, the black hole emits a spectacular plasma stream. Such a spectacular scene is caused by star fragments swallowed up by black holes, which had never been observed by Eastern foreign immortals before. Plasma jets produced by black holes are called 'relativistic jets' and can reach hundreds of thousands of light-years in length. Most galaxies have supermassive black holes in the center of which are equivalent to millions or even billions of suns and devour all nearby matter with powerful gravity.
"The oriental fairy thousand-mile mirror observed the scene of stars being swallowed up by supermassive black holes. The star was finally destroyed because it was too close to the giant black hole. Some oriental foreign immortals have said that the chemical analysis of bright ultraviolet flash shows that the flash comes from substances swallowed up by black holes. The size of this black hole is equivalent to one million suns. And pointed out: 'We think we have captured the scene of a supermassive black hole jet relativistic jet.'
"Oriental Immortals believe that in a galaxy, the event of black holes devouring stars occurs every 100 million years. As the devouring star gains more mass, the energy of this black hole is further improved. Devouring stars or other black holes is an important driving force for the 'growth' of black holes, which also breeds supermassive black holes. The mass of a massive black hole can be equivalent to billions of suns. Black holes are out of reach and humans will not be killed in seconds.
"The great pessimistic immortals of the Western Immortals are all pessimists and a handful of pessimists in the East have agreed that in the center of the vast Tianhe system, there is a super black hole constantly devouring the surrounding matter. In addition, there are hundreds of medium-sized black holes in the Tianhe system, which are also absorbing matter crazily. Black holes have a powerful gravitational field, and even light can't escape. One day, the earth will be sucked in by black holes, and human beings and their created civilizations will never come back...
"Contrary to my silent immortals in the west, the vast majority of oriental immortals are optimists. Oriental optimist immortals believe that the idiom of 'unfounded worry' tells them that they can have a sense of worry, but it is ridiculous to exaggerate certain worries and even evolve into panic. Worrying about the 'black hole' and thinking that it will impact, threaten and even destroy the earth in the near future is just an unfounded act. Oriental foreign optimist immortals advocate preparing for a rainy day, but refuse to worry about the sky. Optimist immortals in the East believe that exploring the unknown world should not rely on worry or fear, but should use the beacon of practice to guide the way. Of course, it's just that they themselves think of immortality. In fact, they are wrong. They only live a long life in millions of years. Even if life expectancy is equivalent to a star, there will eventually be a day of extinction. In the past 100 years, immortals in the East have benefited from the progress of detection equipment and the improvement of astronomical observation methods. News about the discovery of black holes are common, such as 'a certain fairy found a ten-year-old black hole', 'some fairy found a 20-year-old black hole', and some fairy found a three-year-old fairy. Ten-year-old black hole, cloud. And a variety of simulation studies have been taken, claiming to have come to a definite conclusion that there may be more than 1,000 medium-sized black holes and clouds in the Tianhe system. Because black holes have a powerful gravitational field that devours the interstellar matter around them, some people worry about whether black holes will also swallow our earth, and some people even associate black holes with the upcoming 'Great Catastrophe' of a certain year...
"The following is the whole process of an interview with an oriental fairy:
Q: When it comes to a black hole in the world, people's first reaction is that its mass is so large that it will devour all objects around it. Why do black holes inhale interstellar matter, and how is this achieved?
Answer: Mainly through the powerful gravitational field. Generally speaking, black holes are usually referred to objects that are small enough and have a strong enough gravitational field after the collapse of massive stars. As long as matter enters a certain area near it, the black hole can absorb anything, including light, making it impossible for them to escape by any physical mechanism.
Q: Why can stars shrink and collapse into black holes?
Answer: After the formation of stars, like the sun in their prime, there is a violent nuclear fusion reaction inside, showing an outward expansion or ejection of material, which is also constantly consuming its own energy; at the same time, it also shows a trend of contraction under its own gravity. After hundreds of millions to billions of years of evolution, the energy of fusion inside the star is gradually exhausted, and the collapse effect of gravity gradually plays a leading role. Strong collapse may trigger an explosion and be accompanied by the ejection of star material. When the mass of the remaining material is greater than three solar masses, the star will continue to collapse, and the huge gravity will cut off the connection between all matter in the star and the outside world, and eventually form a black hole.
Q: Is the 'black' of the black hole due to the 'no light'? Since no matter can come out, how do we know its existence?
Answer: Black holes are first seen by successful immortals with 'sky eyes'. Of course, not all people who practice heavenly eyes can see the existence of black holes, and the vast majority of people who practice heavenly eyes can't feel the existence of black holes at all. A thousand years ago, there was an oriental fairy who practiced well and thought that there was a star that could attract all substances, including light and not allow it to escape. It would look like a dark hole. This fairy just felt that there was a star that would look like a dark hole, 500 A year later, another oriental exortal who has been cultivated into heaven claims to be able to analyze a space-time region with strong gravity, which is the 'black hole'. When a strong gravity causes a star to shrink to a certain critical radius, this means that any radiation, including light, will be completely inescapable. The existence of black holes is mainly indirectly determined by the gravitational field outside the visual interface.
Q: Will interstellar matter be swallowed up by black holes as soon as they enter the circumference of this radius?
Answer: Yes, in fact, the area within this radius is a one-way membrane area. As long as any substance enters this radius, there is no chance of 'outward' movement. Therefore, this radius is the critical point of two completely different space-time attribute areas, which is also known as the 'visual field'. The area within the horizon is a black hole.
Q: The power of black holes will also devour the earth, right?
Answer: In terms of the strength of the gravitational field alone, a black hole can devour any matter, including a star, as long as it is close enough to the characteristic 'vision' of the black hole. Therefore, there is no doubt that black holes can devour the earth as an ordinary planet in the solar system. The earth is only the most common star in the ten-square world - the planet of the sun, which can be described as a drop in the ocean in the ten-square world. If a sufficiently large black hole appears close enough to the solar system, even if the solar system is not within the event horizon of the black hole, the gravity generated by the black hole may break the balance of forces between the planets in the solar system and pull the planets away from their orbit, which must be a disaster for humans living on Earth. Q: Where is the nearest black hole to our earth? I heard that there is a supermassive black hole in the center of the Tianhe system?
Answer: Through observation, it is found that there are tens of billions of stars in the Tianhe system, all of which rotate at high speed around the center of the Tianhe system. What force can drive these stars to rotate? There must be an extraordinary great gravity pulling these stars. We can't see the interior of this center directly, but by observing the trajectory of the star, we can calculate the mass of its center. It is speculated that it is likely to be a supermassive black hole with a mass of about 5 million times that of the sun, but it occupies a small space and continues to grow by devouring the surrounding interstellar gas. At present, the nearest black hole observed to the earth should be in the Milky Way. The diameter of the Milky Way is 280,000 light-years, while the sun is about 380,000 light-years away from the center of the Milky Way, so in fact we are not far from the central black hole of the Milky Way. In other stellar systems near the solar system in the Tianhe system, it is likely that there are stellar black holes, and they may be closer to us. However, the black hole is not terrible, and its impact on us is nothing more than the effect of gravity. Although it has a strong gravitational field, it should be close enough. In fact, isn't it terrible for the earth to fall directly to the sun if it doesn't revolve? However, the revolution of our earth brings pleasant four seasons, and the right distance between the sun and the earth just provides the source of all life and energy on earth.
Q: Is it possible for some people to worry about whether our earth will be sucked into by black holes?
Answer: Whether it is a supermassive black hole or a star black hole at the center of the Milky Way, there seems to be no sign of any abnormal impact on the earth. Black holes can indeed swallow the earth, but the problem is that our earth and even the solar system are not within such a black hole to devour and attract, just like a shark can eat people, but how can a shark eat you in the mountains of land?
Q: Can't black holes reach the earth?
Answer: Yes, this is from the point of view of 'space'. In terms of time, the general process of the formation of black holes has just been introduced. Astronomical events such as the birth and formation of black holes are calculated for tens of millions or even billions of years. In comparison, human beings are too small and short, so even if there is any change in the black hole 'close' to the earth, it is extremely slow. It is difficult to make any major changes on the scale of the next millennium, and it will not have any substantial impact on the earth. Even if a black hole in the Milky Way or other galaxies is newly observed, it has already existed there, and there will be no abnormal changes because you find it. The formation and evolution of celestial bodies in the ten directions of heaven and earth are similar to the birth and demise of life on our earth, but the time and space scale are larger, which is very common. We don't have to worry about discovering black holes, because our astronomical observations can see a distance of billions or even tens of billions of light years. Whether black holes are found is just whether we know more about the ten-way world.
Q: If black holes continue to devour objects, will the mass and gravity increase, and the scope of the event horizon become larger and larger? Will black holes die once they are formed?
Answer: According to the current theoretical research results, if black holes continue to devour objects, their mass and gravity will increase, and the range of event horizons will become larger and larger, but such a process cannot continue endlessly. There are two reasons for this. First, whether there is more matter 'fed' around the black hole. If the matter is gone or if the matter rotates around the black hole long enough at a large enough speed, the phagocytosis process will end. Second, a fairy with great achievements predicted as early as 300 years ago, considering its In the quantum effect near the horizon, black holes can produce 'thermal radiation' and then return their energy to the ten squares in the form of 'black body thermal radiation', and even eventually disappear.
