Among the population of 100,000, about 40,000 live on the Spark spacecraft. This includes 36,000 minors, 4,000 teachers, childcare, security, scientific research and other personnel, as well as some floating population, such as visiting relatives.
Vacation and the like.
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 one that can accommodate 15,000 people.
In the Earth City where humans live, there are still 40,000 people left, so they can only temporarily make do with living in dormitories among the many comprehensive bases.
During this period of time, the private economy has quietly emerged, and there are vague signs of division into social classes. Specifically, people living in Human City and Earth City have vaguely become one class, and those living in the collective dormitories of the comprehensive base have become one class.
Human beings 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 started to deal with some bad phenomena that appeared in society.
Cleaned.
The result of the purge was the emergence of the first prison in the history of new mankind - 37 people were imprisoned in it. In addition, 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. Because in his opinion, everyone is his own child, but now, he wants to execute his own child.
.
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 that before the disaster in the Earth era. The main reason is that the medical technology 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, the normal mortality rate 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 figure 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 shaft of the Spark spacecraft, which is even more than a candied haws of sugar. If more circles are added, the main shaft will break. The only way is to directly build a new one. And the current technology
It is temporarily unreachable.
But that's for the future. There are still several decades before the population reaches the upper limit of 200,000.
During this period of time, the task of building human civilization was 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, supermarkets, medical centers, subways and other supporting facilities have been built in the city.
Now, anyone who has just grown up without parents can afford a house in the city. Those who cannot afford to buy an old house in Sun City, Human City, and Earth City can always afford it.
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 and 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, separate and scattered industrial concentration method is slowly being 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 will be connected by railways, which can very conveniently transport materials and materials.
Movement of personnel.
When this work was completed, it was already the 216th year of the New Calendar. Zhao Changxing worked non-stop and immediately started planning for the next task.
"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, I don’t know how many heads of different departments have changed, so many that Zhao Changxing can hardly remember them clearly. But it doesn’t really matter. All Zhao Changxing needs is someone who can handle the tasks within this category.
Just bear it.
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 indispensable. Because only it can complete the transportation of huge amounts of materials economically, quickly and conveniently.
"Yes, leader."
The heads of each department 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" this piece of information, or the meaning of the statement. For example, if a statement consisting of three waveforms "X, B, F" is guessed as "1 is smaller than 2", the result is another
If the sentence "F, B, X" appears in a sentence, it obviously proves that the previous guess is wrong, and this meaning can be eliminated.
In the actual deciphering process, Xiao Xi will 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. In this process, most of the guesses will be eliminated.
Only a few guesses can be retained. By repeating this, you can finally get a deciphering result that is close to the truth.
There is a prerequisite for using this method to decipher, that is, the number of specimens must be sufficient. Only with enough specimens can the purpose of eliminating wrong guesses be achieved. This is why Xiao Xi has only completed the preliminary decipherment until now.
Of course, in the process of deciphering, the possibility of meaningless sentences, structurally incorrect sentences, etc. must also be considered. The real algorithm design is extremely complicated and can even be expanded into a professional book. Zhao Changxing doesn’t understand this very well, but
He just knows that Xiaoxi has this function.
At this moment, Xiao Xi initially completed the deciphering results and presented them 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 decryption. 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 extent description),"
"We are the last XXX (unknown) of XXX (suspected noun), we are 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 the distance. But since the information mentions "stars and black holes", and the sun is being swallowed by that black hole at this moment, Zhao Changxing cannot help but suspect that they are in the solar system, in Seder
Naxing is near.
"Concentrate all your efforts and launch an all-out search in the direction of Cygnus."
"OK."
At this moment, human civilization has considerable industrial strength, which is enough to build space telescopes with considerable precision. Under Zhao Changxing's promotion, up to twenty new space telescopes have entered space in just a few years, joining the
Searching.
The result 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 does, the only explanation is that there are some things on it.
Specially, it is very likely that the activities of intelligent life have 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, thus allowing Sedna to have a thin atmosphere for a short time.
