There are countless celestial bodies in the vast universe, and stars are the most common and common kind of celestial bodies. Stars are very important celestial bodies in the universe. Perhaps many people are limited to the simple cognition that stars can emit light and generate heat, and can bring some light and warmth.
But in fact, stars determine the evolution of the universe. We all know that the universe was born in the Singularity Big Bang 13.8 billion years ago. At the moment of the Big Bang, energy was transformed into the most basic elements such as hydrogen and helium under the action of ultra-high temperature. Among them, the hydrogen element accounts for the mainstream, reaching more than 90%.
If the universe had only the basic elements of hydrogen and helium, it would not be possible to form the colorful universe in the future. The evolution of the universe, the formation of planets, galaxies, and life all require the coordination of multiple elements. There are currently as many as 118 cosmic elements discovered by mankind, and there are more than 60 elements that make up the human body.
In addition to the elements of hydrogen and helium in the universe, how did the other 110 kinds of elements come from? Here we have to mention the star, which is an important element refinery in the universe. Soon after the birth of the universe, the first batch of massive stars formed. They converted hydrogen and helium into some heavy elements through nuclear fusion. The masses of these stars are very large, and their life spans are naturally very short, perhaps only tens of millions of years.
Supernova explosions will occur after the star’s lifespan is reached. In this process, a variety of heavy elements will be formed, and the elements of the universe will continue to be enriched in this way. With multiple elements, planets, galaxies, life, etc. can be born. Therefore, in a sense, stars can be regarded as the mother of life. Without it, there would be no living planets or the birth of intelligent life.
The star is also the bright light of the universe, and the light and heat it burns brings some light and warmth to the dark and cold universe. After human beings walked out of the earth, an important helper in exploring the universe is the star. If there is no photon emitted by the star, our astronomical telescope is a blind man and cannot observe the existence of any celestial body.
It is with countless stars that continuously emit light that we can observe the starry sky tens of billions of light-years away. Therefore, after human beings walked out of the earth, they began to mark the stars in the universe and formed a stellar table. In the old stellar table, scientists marked a total of 150,000 stars.
With the continuous improvement of human observation technology, the number of observed stars is also increasing, and the star table is constantly updated.
The stars in the new stellar table should theoretically contain all the stars in the old stellar table, but in a computer comparative analysis. Scientists discovered that 100 stars only appeared in the old table, but not in the new table. This shows that these 100 stars have mysteriously disappeared. Where did they go?
Some people may say that stars have a lifespan, and these 100 stars may disappear in the universe after their lifespans. Is this really true? In fact, this explanation doesn’t make sense. You must know that the lifespan of stars is generally more than billions of years, and the lifespan of yellow dwarfs like the sun is even more than 10 billion years.
Even after stars evolve to the end, they will explode in supernovae. And this is a very powerful release of energy, the entire state of explosion can last for tens of thousands of years, so even if the star will die, it is a continuous process and will not suddenly disappear from the universe. And these 100 stars are not distributed in one area, but distributed in all directions of the starry sky and at different distance scales.
Therefore, after analysis, scientists believe that they can basically be ruled out. If it doesn’t disappear naturally, what will happen? At this time, scientists thought of the Dyson sphere theory proposed by Freeman Dyson in 1960.
I believe that many of my friends have heard of the Dyson Sphere theory. In many science fiction works, it is also a kind of advanced civilization artificial device that often appears. To put it simply, this is a super-giant man-made device that can envelop a star. The purpose is to perfectly absorb the energy of the star.
We all know that the rapid development of human science and technology cannot do without the support of energy. The amount of energy, the strength and weakness, directly determine the strength and development speed of a civilization. With the rapid development of human science and technology, our energy requirements and levels are constantly increasing. It is foreseeable that in the near future, the earth’s energy will not be able to meet the needs of human development.
At this time, we need to go to space to mine energy. What energy is the most powerful in the solar system? It is undoubtedly the huge star sun at the center. If we can absorb 100% of the energy from the sun, then human development will no longer worry about energy.
Human beings will think of using the energy of the sun, so other intelligent civilizations in the universe can naturally also think of. Dyson believes that when a civilization develops to the second stage of civilization, it needs the powerful energy of stars to support it, and to absorb the energy of stars more efficiently, a huge device around the sun is needed. This device is the Dyson sphere. .
Therefore, if the 100 stars that disappeared suddenly did not die out naturally, then there is a great possibility that they were covered by the Dyson sphere. The energy radiation emitted by the star is absorbed by the Dyson sphere, and naturally there is no bright energy released into the universe, and we naturally cannot observe it.
Such discoveries and speculations undoubtedly make us more convinced of the existence of alien civilization. You know, after leaving the earth, human beings have been trying to find alien civilizations. However, more than half a century has passed and we have not found anything. The reason for this is not to say that alien civilization does not exist, but because humanity’s scientific and technological strength is still very weak, and we have not been able to truly explore other galaxies.
In the past, we used various methods such as spacecraft and radio telescopes to find extraterrestrial civilization, but to no avail. Later, some scientists proposed that extraterrestrial civilization could be discovered by searching for Dyson spheres, so scientists began to track and analyze a large number of stars marked by humans, which really allowed us to discover a lot of anomalies.
The sudden and mysterious disappearance of 100 stars this time undoubtedly boosted our confidence in the search for alien civilization. Compared with these 100 mysteriously disappearing stars, the light and dark changes of some stars often occur regularly and abnormally. For example, the Tabby star in the constellation Cygnus 1500 light-years away is even more outstanding. Its light and dark changes are unusually obvious, and it is also the star that scientists believe is most likely to have a Dyson sphere device.
If scientists are correct in their speculation about the disappearance of these 100 stars, it means that the universe is very lively, civilizations are everywhere, and humans are not alone. At the same time, it also tells us that mankind may face more space challenges in the future. Even if the dark forest law does not exist, the principle of being weak and being beaten is also applicable in the universe.
The human beings are also very envious of the Dyson ball, and hope that humans can also build a sun to enclose the sun in the future. But in fact, to build a Dyson ball is far from as simple as we thought, technology is only a small aspect, and more importantly, we need huge construction resources.
We must know that the mass of the sun accounts for 99.86% of the total mass of the entire solar system. To enclose the sun, it is not enough to add up all the celestial bodies except the sun. We need to mine the resources of other galaxies outside the solar system, and it is even more difficult to mine resources outside the system. We need to achieve preliminary interstellar voyages.
Therefore, to build a Dyson ball, the technology may be mastered before the second level civilization. But to truly build, we may need to develop to the middle and late stages of the second-level civilization or enter the third-level civilization before we can hope to achieve it. Human beings are currently only level 0.7, which is far away from the second-level civilization or even the third-level civilization. We still need a longer development time.
