Chapter 497: Dyson Ball

Even during the Spring Festival, many people voluntarily stick to their posts.
In this era, it is undoubtedly painful for many people. From the beginning of the last days, the corpse is full of corpses, and it is completely devastated. To the precarious era of the reconstruction area, it struggles for survival and has a strong sense of insecurity, always lingering in the heads of all people.
Even in today's era of technological explosion, society has once again become temporarily stable, but the wolf will flee to the reality, still a sense of anxiety in the human heart.
Fortunately, this kind of anxiety is not all bad. It makes human beings work harder and pay more attention to selfless dedication. This is especially obvious among the researchers. About 60% of them are still in the normal business. Work, even about 10% of people, did not go home on the day of the Spring Festival.
Of course, this also has the special reason of this kind of people. For scientific research work, it is a basic quality to sink the heart. Most of them, almost every day, deal with cold instruments and boring numbers. People who are patience will be eliminated first. And for them, there is no more project that will break through, it will be tempting and addictive. At this time, even the family should be put aside.
As the highest level of Luo Yuan, there is no leisure.
On the third day of the Spring Festival, the Foreign Intelligence Service sent an e-mail, and the specific information about Bolivia has been sorted out.
The Extraterritorial Intelligence Service is affiliated with the foreign intelligence organization directly under Luo Yuan. It is an important part of the spaceship space army. It is responsible for collecting all nearby satellite information, including but not limited to capturing signals from extraterrestrial civilizations, planning safe satellite routes and investigating nearby areas.工具 Earth-based planet for the future.
However, the most important task at the moment is to collect information about Bolivia and analyze the technological level of Bolivia.
............
The spacecraft is in the control room.
"The mayor, Zhinao has very few information about the glass star, this is the only video we found on the spacecraft brain!" Wu Xinfan, director of the Extraterrestrial Intelligence Department, transferred the video to the three-dimensional screen of the spacecraft control cabin. Originally a professor of university astronomy, after the establishment of the extraterritorial intelligence office, he was recruited here and served as the director.
In fact, many people in this department are like this. Because of their strong professionalism and lack of academic ability, they do not adapt to this position. Many people here are originally academics, including mathematics, astronomy and The largest number of physical fields, not so much an intelligence service, is better than a special research institution.
Luo Yuan patiently looked at it for a while. This is a video of a Bolivia man who is about to land on the spaceship. There are many people around the world, surrounded by countless Bolivia people. The scene is quite lively.
He can imagine the kind of fanaticism at the time.
For the Bolivia, this expedition is undoubtedly of great significance. This is a leap of their civilization, representing the first step from the civilization of the stellar system to the development of interstellar civilization, and the first time the aliens launched a war, but unfortunately the final The ending is not good.
The video was shot with a starburst.
Luo Yuan looked at it for a long time and couldn't see which one it was. For their appearance, Luo Yuan had a serious face blindness. This did not help much with the abnormal memory, but this Bolivia was obviously killed by it. One of them, and seeing it in the crowd of people, the prosperous prestige, should be the captain undoubtedly.
However, Luo Yuan is not paying attention to this. The location here is obviously not on the planet. Through the transparent wall like glass, Luo Yuan sees a dark space outside.
"This is a space mooring port! Look at these few small points!" Wu Xinfan explained next to him.
Wu Xinfan pointed to a few invisible spots on the corner of the screen: "This is a few spaceships that are about to stop, indicating that their space navigation is very common."
Luo Yuan nodded, but he was not astonished. In the dream of the Boshien, he has seen many scenes of the Bolxing society. It has long been strange, this is a highly prosperous civilization, powerful technology, let Space navigation has long been a common mode of transportation.
Otherwise, no interstellar spacecraft will be created. Just like humans, shallow sea navigation has long been popular before sailing into the ocean.
Wu Xinfan pointed to the picture and continued: "Fortunately, the angle of the video is very good and very clear. We can see the stars not far away, that is, the sun of the star."
Luo Yuan discovered that maybe the other party was a teacher for a long time. When he explained, there was always a taste of martyrdom, but he did not urge him. Obviously, the other party will soon talk about the key moment.
"We can see that its brightness is very high. According to estimates, its brightness is one-three times that of the sun."
Immediately, Wu Xinfan removed the video and replaced it with a pattern: "This is a stellar map of the star we shot. After the compensation and correction of the light source, we basically restored the scene of the star system!

Luo Yuan discovered that in the galaxies, he saw three planets like the blue and white of the Earth. He could not help but interrupt: "Which is a glass star?"
He doesn't know much about astronomy, but he knows that this color is distinct, and part of it is still a blue planet. Most of the climate is stable, the temperature is right, and there is a lot of water.
"It is still impossible to distinguish, because these three planets are all inhabitable planets. The Bolivians already have the ability to transform the planet!" Wu Xinfan replied, saying that one of the planets was enlarged, and Luo Yuan suddenly saw the planet floating outside. A lot of black spots, can also see the ups and downs of the terrain on the surface of the planet, many places have traces of artificial exploitation.

Can you continue to zoom in?

Wu Xinfan shook his head: "The mayor, zooming in is meaningless, there are nearly thirty light years away from here, the exact distance is 28.5 light years (previously modified), and then huge objects, even planets, at such a long distance It becomes smaller than the tip of the needle.
In addition, the light of the planet is much weaker than that of the stellar light. Even if the spacecraft's advanced optical detection system captures the image, it is still in a state of severe distortion. The scene we see now is only the compensation and correction of the light source. As a result, the larger the release, the more severe the distortion, and can only be used as a reference at most.

Luo far nodded.
Wu Xinfan continued the previous topic: "By comparing images and patterns, we found an important piece of information. The actual brightness of this star is brighter than what we observed.
Originally, we didn't care much. After all, there was always some distortion in the distance. Even the intelligent light source compensation of this optical detection system could not be restored perfectly. Until recently, we compared the images taken a year ago and finally confirmed one point.

Luo Yuan frowned and asked: "What do you think is the reason?"

There are many reasons, such as the sudden stellar flares when shooting recently, or the last time the image was blocked by asteroids, but the biggest possibility is to artificially cover a part of the sun.

"What are you talking about Dyson?" Luo Yuan thought sharply and suddenly thought of a famous theory.
"There is such a possibility, we have found some key evidence for this!" Wu Xinfan expanded the stars in the two patterns taken one year apart.
Luo Yuan took a closer look and immediately found that there was a black spot on the surface of the two patterns. If it was only a pair, it might be thought of as a meteorite, or something else, but two of them, and one year apart, It is already obvious.
What's more, compared to the recent shooting, the black spot is obviously bigger than the former.
......
Dyson Ball is a theory that Freeman Dyson proposed in 1960. The theory holds that the planets such as Earth have very limited energy resources, which are far from enough to support the development of civilization to the advanced stage. In a stellar-planetary system, most of the energy – radiation from stars is wasted.
The sun radiates 2,860 billion megawatts of light per second, and it can supply humans for 270,000 years, which is more than the history of mankind, based on the total amount of energy consumed by the seven billion productive activities of the last human race. Long, this is only the energy emitted by the sun for a second. If it is a day, if it is a year, it will be a terrible astronomical number.
Therefore, this theory holds that a highly developed civilization must have the ability to surround the sun with a huge spherical structure, so that most of the radiant energy of the sun is intercepted. Only in this way can the civilization be supported for a long time, so that it can develop enough. height.
Once this theory was put forward, it was immediately recognized by many scientists as a step that must be experienced for civilizations to get out of the star system. However, in any case, this is only a hypothesis. The scientific and technological capabilities of human beings are far from being verified. I think that I can see it today.
Although this black spot is not large, it is only about one-fifth of the area of ​​the cross section of the star, and it is far from being able to achieve the complete Dyson ball. But this star is 28.5 light years away from the Earth, even if it is now shot, They are also historical pictures of 28.5 years ago. After so many years, I am afraid it is no longer the original appearance.
The total amount of energy produced and applied by a civilized race often reflects the level of science and civilization of a civilization, from the coal-fired era of the human industrial revolution, to the next era of thermal power, to the current era of nuclear fusion, and The total amount of energy used is almost geometrically increasing.
And even if the Bolivia is still incomplete Dyson's ball, the energy it produces is also desperate for humanity. Its power is far more than the strength of a spaceship, and even one in ten thousand.
This is undoubtedly a blow to Luo Yuan, who is thinking about revenge on Bose.
"For this Dyson ball, technical demonstration and feasibility analysis, maybe not needed now, will certainly be used in the future." Before leaving, Luo Yuan said with a dignified look.
