Among the population of 100,000, about 40,000 live on the Spark spacecraft. This includes 36,000 minors, as well as 4,000 teachers, childcare, security, scientific research and other personnel, as well as some floating populations, such as visiting relatives and taking vacations.
All the remaining 60,000 people live on Sedna, supporting the industrial system on Sedna. In these years, in addition to the already completed human city, Zhao Changxing also built a larger earth city that can accommodate 15,000 people. There are still 40,000 people left, so they can only temporarily make do with the numerous comprehensive bases and live in collective dormitories.
During this period, the private economy has quietly emerged, and there are vague signs of division into social classes. Specifically, people living in the human city and the earth city are vaguely one class, and those living in the collective dormitories of the comprehensive base are another class.
Zhao Changxing showed a high degree of vigilance about this.
Zhao Changxing always remembers his mission, and he always believes that the fruits of civilization's development must benefit everyone, so that a civilization can maintain long-term vitality. Therefore, he reluctantly began to clean up some bad phenomena that appeared in society.
The result of the purge was the emergence of the first prison in the history of new humanity - which housed 37 people. Also, 4 people were executed under his direct order.
In the process of signing for execution, he hesitated several times and was so sad that he could not even write with the pen in his hand. Because in his opinion, everyone is his own child, but now, he wants to put his own child to death.
But he finally gave the order.
Appropriate punishment is also a necessary means to maintain the healthy functioning of society.
Now, the development of the entire civilization has entered a certain stage of balance. The population is steadily increasing, the industrial level is steadily improving, and the number of various buildings, such as various bases, is also increasing.
Before the total population reaches 200,000, there are no insurmountable obstacles.
Here on Sedna, the annual death rate of the total population is about one percent.
This ratio is about twice what it was before the disaster in the Earth era. The main reason is that the medical technology here on Sedna is still insufficient and the harsh environment has led to too many accidental deaths.
There is no way to reduce this ratio for the time being.
This means that once the total population reaches 200,000, normal mortality will result in a loss of approximately 2,000 people per year, which is equal to the annual increase in population.
If the number of new people cannot increase again, the total population of human civilization cannot exceed the number of 200,000.
To increase the number of new people again, it is no longer feasible to continue to expand the Spark spacecraft.
Now, a total of 55 circles have been connected to the main axis of the Spark spacecraft, which is simply more candied haws than a candied haws. If you add more circles, the spindle will break. The only way is to directly build new ones. And the current technology is temporarily out of reach.
But that’s for the future. There are still several decades before the population reaches the upper limit of 200,000.
During this period, the task of building human civilization is still arduous. Based on the concept that "the development of civilization must benefit everyone", Zhao Changxing once again presided over the construction of a larger third city with more complete facilities - Sun City.
The floor height of Sun City is as high as 60 meters. For the first time, the internal construction method is mainly based on buildings. A large number of 8-story buildings with a floor height of 5 meters have been built, directly increasing the city's population carrying capacity to 100,000 as never before. Several parks have been built in the city, and various supporting facilities such as supermarkets, medical centers, and subways are also available.
Now, anyone who has just grown up without parents can afford a house in the city. Those who can't afford it in Sun City can always afford old houses in Human City and Earth City.
People who are born through artificial wombs and have no savings from their parents can always afford a house as long as they work hard with the support of various policies specially formulated by Zhao Changxing.
After Sun City, Zhao Changxing had no plans to build any more large cities for the time being, but instead put all his energy into the industrial zone.
The previous open-air, fragmented and scattered industrial concentration method is being slowly abandoned by him. He plans to build special industrial concentration areas according to different industrial categories.
These industrial concentration areas will also adopt an urban-type construction method. The internal working environment can directly support people's survival and be as spacious as possible. Different concentration areas are connected by railways, which can facilitate the flow of materials and people.
When this work was completed, it was already the 216th year of the New Calendar. Zhao Changxing didn't stop and immediately started planning for the next mission.
"The current technical reserves are almost enough. Let's build a space elevator."
Facing the heads of different departments such as the Industrial Department and the Scientific Department, Zhao Changxing said this.
Over the years, there have been countless changes in the heads of different departments, so many that Zhao Changxing almost lost count. But it doesn't really matter. All Zhao Changxing needs is someone who can take on tasks within this category.
After all, it is too inconvenient to assume the responsibility of connecting space and the ground through a spacecraft. If you want to enter space on a large scale, a space elevator is essential. Because only it can complete the transportation of huge amounts of materials economically, quickly and conveniently.
"Yes, leader."
The heads of various departments agreed at the same time.
But just when the space elevator was still in its early stages of demonstration, another sudden news disrupted Zhao Changxing's arrangements.
This piece of news comes from Xiaoxi.
"Captain, so far, I have received a total of more than 1,000 radio signals of unknown meaning from the direction of Cygnus. Because there are enough specimens, I have completed part of the deciphering of these messages."
Zhao Changxing's expression immediately became serious.
"Show it to me."
Xiaoxi's principle of deciphering unknown information is to first set each individual waveform to an unknown number, such as X, X1, X2, A1, etc. In this way, a piece of information can be turned into a string composed of many unknown numbers.
After that, it will first "guess" the piece of information, or the meaning of the statement. For example, if a sentence consisting of three waveforms "X, B, F" is guessed as "1 is smaller than 2", but the sentence "F, B, X" appears in another sentence, then it will be very difficult. Obviously it proves that the previous guess is wrong, and this meaning can be eliminated.
During the actual deciphering process, Xiao Xi would first give it possibly tens of millions of meaning guesses for each sentence, and then use these guesses to fit the rest of the sentences. During this process, the vast majority of guesses will be eliminated, and only a small number of guesses can be retained. By repeating this process, you can finally get a deciphering result that is close to the truth.
There is a prerequisite for deciphering in this way, that is, the number of specimens must be sufficient. Only with enough specimens can we achieve the goal of eliminating wrong guesses. This is also the reason why Xiao Xi has not completed the preliminary deciphering until now.
Of course, in the process of deciphering, the possibility of meaningless sentences, incorrectly structured sentences, etc. must also be taken into consideration. Real algorithm design is extremely complex and can even be expanded into a professional book. Zhao Changxing didn't know much about this, but he knew that Xiao Xi had this function.
At this moment, the results of Xiaoxi's preliminary deciphering were presented in front of Zhao Changxing.
There are a large number of characters "***XX" in the deciphering result, which is obviously the part that Xiaoxi failed to complete. The "()" that follows is Xiaoxi's guess about the meaning of this part of the sentence.
"XXX (suspected quantifier) star is being swallowed by black hole XXX (verb, suspected)."
"There is no value for XXX (suspected noun) here."
"Wandering XXX (Unknown), you can stay here, we XXXX (Unknown)."
"Our XXX (suspected vehicle) was damaged to XXX (suspected degree description),"
"We are the last XXX (unknown) of XXX (suspected noun), we XXX (unknown)."
…
Zhao Changxing looked serious and looked at these deciphering results without saying a word for a long time.
This information seems to describe a "collective" that wandered and fled in space for an unknown number of years, and lost an unknown amount of manpower and resources. When it was about to perish, it finally arrived at this place being swallowed by a black hole. For another galaxy that has no value to the "collective", it plans to survive here, regain its strength, and then start another escape.
"Could it be that there has always been another civilization near us? The survivors of that civilization are just like us, trying to rebuild civilization..."
This information cannot determine distance. But since the message mentioned "stars and black holes", and the sun was being swallowed by that black hole at the moment, Zhao Changxing couldn't help but suspect that they were in the solar system, near the Sedna star.
"Concentrate all your efforts and launch an all-out search in the direction of Cygnus."
"OK."
At this moment, human civilization already has considerable industrial strength, which is enough to build space telescopes with considerable accuracy. Driven by Zhao Changxing, in just a few years, up to twenty new space telescopes entered space and joined the search.
The results appeared in the fifth year.
"Captain, 63 million kilometers away from us, I discovered a dwarf planet that humans have never discovered before. And... it has a certain atmosphere."
A dwarf planet that is so far away from the sun, so cold, and so tiny cannot have what is called an atmosphere in a macro sense. But now that it has it, the only explanation is that there is something special on it, most likely the activities of intelligent life that caused this phenomenon.
Just like the heat released by human activities on Sedna, it will also cause dry ice, solid gas, thorin, etc. to sublimate, causing Sedna to have a thin atmosphere for a short time.
