Epoch of Twilight

Even during the Spring Festival, there are still many people who voluntarily stick to their posts.

In this era, it is undoubtedly painful for many people. From the beginning of the end of the world, corpses littered the fields and fell to the precariousness of the reconstruction zone era, struggling for survival, and a strong sense of insecurity always haunts everyone.

Even in today's era of technological explosion, society has once again become temporarily stable, but the anxiety that is about to escape to reality still lingers in the hearts of human beings.

Fortunately, this kind of anxiety is not all a bad thing. It makes human beings work harder and pay more attention to selfless dedication. This is especially obvious in the group of scientific researchers. About 60% of people are working as usual. Work, even about 10% of people did not go home on the day of the Spring Festival.

Of course, this is also due to the particularity of this type of people. For scientific research, calmness is the most basic quality. Most of them deal with cold instruments and boring numbers almost every day. Those who are patient will be eliminated first. And for them, there is no project that is about to break through, which will be heart-wrenching and addictive. At this time, even the family must be put aside first.

And Luo Yuan, who is at the top, also has no time to be idle.

On the third day of the Spring Festival, the Extraterrestrial Intelligence Office sent an email, and the specific information about Boxing had been sorted out.

The Extraterrestrial Intelligence Department belongs to the foreign intelligence organization directly under Luo Yuan. It is an important part of the spacecraft space force. It is responsible for collecting all nearby star field information, including but not limited to capturing signals of extraterrestrial civilizations, planning safe star route routes, and scouting nearby The terrestrial planets in the star field are preparing for future voyages.

However, the most important task at the moment is to collect information about Boxing and analyze the technological level of Boxing people.

…………

In the control room of the spaceship.

"Mayor, the intelligence brain has very few data images about Boxing. This is the only video we found on the spacecraft intelligence brain!" Wu Xinfan, director of the extraterrestrial intelligence department, transferred the video to the 3D screen of the spacecraft control cabin. He was originally a professor of astronomy at the university. After the establishment of the Extraterrestrial Intelligence Division, he was recruited here and served as the director.

In fact, many people in this department are like this, because they are extremely professional and do not have certain academic ability, so they are not suitable for this position at all. The largest number in the field of physics, it is not so much an intelligence department as it is a special research institution.

Luo Yuan watched it patiently for a while. This is a video of the Bosingians about to land on the spacecraft. There are huge crowds of people around, surrounded by countless Bosingians, and the scene is quite lively.

He could imagine the frenzied scene at that time.

For the Boxing people, this expedition is undoubtedly of great significance. This is a leap forward for their civilization, representing the first step in the development from the civilization in the star system to the interstellar civilization, and it is also the first time to launch a war against aliens. Unfortunately, in the end It didn't end well.

The video was shot with a Bostian as the main character.

Luo Yuan looked at them for a long time but couldn't tell which one it was. Regarding their appearance, Luo Yuan had severe face blindness, which didn't even help much with his perverted memory, but this Boxing man was obviously killed by it. One of them, and seeing that it is popular among the crowd, and its costumes are popular, it should be the captain without a doubt.

But Luo Yuan didn't pay attention to these. The location here is obviously not on the planet. Through the transparent glass-like wall, Luo Yuan saw a dark space outside.

"This is a space mooring port! Look at these small dots!" Wu Xinfan explained beside him.

Wu Xinfan pointed to a few imperceptible light spots in the corner of the screen: "These are a few spaceships that are about to dock, indicating that their space travel is very common."

Luo Yuan nodded, but he was not amazed by it. He had seen many scenes of the Bosing society in the dream of the Bosing people, and he had long been familiar with it. This is a highly prosperous civilization, powerful technology, so that Space travel has long been a common form of transportation.

Otherwise, interstellar spaceships would not be manufactured. Just like humans, shallow sea navigation has long been popularized before embarking on ocean voyages.

Wu Xinfan pointed to the screen and continued: "Fortunately, the angle of the video is very good and very clear. We can see a star not far away, which is the sun of Boxing."

Luo Yuan found that maybe the other party had been a teacher for a long time, and when he explained, there was always a sense of eloquence, but he didn't urge him, obviously the other party was about to talk about the critical moment.

"We can see that its brightness is very high. According to calculations, its brightness is 1.3 times that of the sun."

Immediately, Wu Xinfan removed the video and replaced it with a pattern: "This is a picture of the star system where Bosar is located. After compensation and correction of the light source, we have basically restored the scene of the star system! "

Luo Yuan found that he saw three blue and white planets similar to the earth in the star system map, and couldn't help but interrupted: "Which one is a glass star?"

He doesn't know much about astronomy, but he also knows that this kind of planet has distinct colors, and some of them are blue. Most of them have a stable climate, a suitable temperature, and a lot of water.

"It is still impossible to tell the difference, because these three planets are all habitable planets, and the Boxing people already have the ability to transform planets!" Wu Xinfan replied, zooming in on one of the planets, Luo Yuan suddenly saw the planet floating outside There are many black spots, and the undulations of the terrain can also be seen on the surface of the planet, and many places have traces of artificial development.

"Can you continue to zoom in?"

Wu Xinfan shook his head: "Mayor, it's meaningless to zoom in. It's nearly 30 light-years away from here, and the exact distance is 28.5 light-years (the previous article has been modified). No matter how huge an object is, even a planet, at such a far distance , becomes smaller than the tip of a needle.

In addition, the light of planets is much weaker than the light of stars. Even the advanced optical detection system of the spacecraft, the images captured by it are still in a state of serious distortion. The scene we see now is only the compensation and correction of the light source. As a result, no matter how large the amplification is, the more serious the distortion will be, and it can only be used as a reference at most. "

Luo Yuan nodded knowingly.

Wu Xinfan continued the previous topic: "Through the comparison of images and patterns, we discovered an important piece of information, the actual brightness of this star is brighter than what we observed.

Originally, we didn't pay much attention to it. After all, there will always be some distortion due to the long distance. Even with the intelligent light source compensation of this optical detection system, it is impossible to restore it perfectly. It wasn't until recently, when we compared images taken a year ago, that we finally confirmed that. "

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

"There are many reasons, such as the sudden stellar flare during the recent shooting, or the possibility that the last image was blocked by an asteroid, but the biggest possibility is that part of the sun was artificially blocked."

"You mean the Dyson sphere?" Luo Yuan thought sharply, and suddenly thought of a famous theory.

"It's very possible, and we have found some key evidence for this!" Wu Xinfan enlarged the stars in the two pictures 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 just one pattern, it might be a meteorite or other sunspots, but both patterns were there, and they were separated by a year. Already obvious.

What's more, compared to the recent one, the black spots are obviously bigger than the former one.

...

The Dyson sphere is a theory proposed by Freeman Dyson as early as 1960. The theory believes that the energy contained in a planet like the earth itself is very limited, which is far from enough to support the development of civilization on it to an advanced stage; and In a star-planetary system, the vast majority of energy - radiation from the stars - is wasted.

The sun radiates 2,860,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 of which can supply humans for 270,000 years, which is more than human history. Long, this is only the energy emitted by the sun in one second. If it is a day, if it is a year, this will be an extremely terrifying astronomical figure.

Therefore, this theory believes that a highly developed civilization must have the ability to surround the sun with a huge spherical structure, so that most of the sun’s radiant energy can be intercepted. Only in this way can this civilization be supported for a long time and develop enough high.

As soon as this theory was put forward, it was immediately recognized by many scientists, who believed that it was a necessary step for civilization to go out of the star system. However, in any case, this is just a hypothesis, and the scientific and technological capabilities of human beings are far from being verified. Imagine being able to see it with your own eyes today.

Although this black spot is not large, it is only about one-fiftieth of the cross-sectional area of ​​the star, and it is far from being a complete Dyson sphere, but the star is 28.5 light-years away from the earth, even if the image taken now, They are also historical pictures from 28.5 years ago. After so many years, I am afraid that it is no longer what it used to be.

The total amount of energy produced and used by a civilized race often reflects the technological level and civilization level of a civilization. From the era of coal steam in the human industrial revolution, to the era of thermal power and electricity, and now to the era of nuclear fusion, the energy produced and The total amount of energy used increases almost geometrically.

And even if the Boxing people are still an incomplete Dyson sphere, the energy it generates makes human beings desperate. Its strength is far beyond that shown by a spaceship, and it may not even have one ten-thousandth of it.

This is undoubtedly a blow to Luo Yuan who still wants to take revenge on Boxing one day.

"The technical demonstration and feasibility analysis of this Dyson sphere may not be needed now, but it will definitely be needed in the future." Before leaving, Luo Yuan said solemnly.
