The last human in the universe

Chapter 46 Deciphering
Out of a population of 10, about 4 live on the Tinder spacecraft.This includes 3.6 minors, 4000 teachers, childcare, public security, scientific research personnel, and some floating population, such as visiting relatives and taking vacations.

The remaining 6 people all live on Sedna, supporting the industrial system on Sedna.During these years, in addition to the already completed Human City, Zhao Changxing also built a larger Earth City that can accommodate 1.5 people.There are still 4 people left, so they can only temporarily make do in the numerous comprehensive bases and live in collective dormitories.

During this period of time, the private economy has quietly emerged, and there are also signs of division of social classes.Specifically, the people living in Human City and Earth City vaguely form a class, and the people living in the collective dormitory 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 development of civilization must benefit everyone, so that a civilization can maintain long-term vitality.So, for some bad phenomena that appeared in the society, he reluctantly began to clean up.

As a result of the cleansing, the first prison in the history of the new mankind emerged—in which 37 people were imprisoned.And, 4 people were executed by his direct order.

During the process of signing the execution, he hesitated several times, and was so sad that he couldn't even write with the pen in his hand.Because in his view, 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 benign functioning of society.

Now, the development of the entire civilization has entered a certain stage of balance.The population is steadily increasing, the level of industry is steadily improving, and the number of various buildings, such as various bases, is also increasing day by day.

Before the total population reaches 20, there are no insurmountable obstacles.

Here on Star Sedna, the annual death rate of the total population is about [-]%.

This ratio is about twice what it was before the catastrophe of the Earth era.The main reason is that the medical technology here on Sedna is still insufficient, and the harsh environment has caused too many accidental deaths.

There is no way to lower this ratio for the time being.

And this means that once the total population reaches 20, the normal death rate will result in a loss of about 2000 people per year, which is equal to the annual increase in population.

In the case that the new population cannot be increased again, the total population of human civilization cannot exceed the number of 20 by too much.

To increase the number of new population again, it is no longer feasible to continue to expand the Tinder spacecraft.

Now, a total of 55 circles have been connected to the main axis of the Tinder spacecraft, which is even more candied haws than candied haws.Add more circles, and the main shaft will break.The only way, is to build new ones directly.And the current technology can't reach it for the time being.

But that's for later.It is still many decades before the population reaches the upper limit of 20.

During this period of time, the task of building human civilization is still arduous.Based on the idea that "the development of civilization must benefit everyone", Zhao Changxing once again presided over the construction of the third city, Sun City, which is larger and has more complete facilities.

The storey height of Taiyang City is as high as 60 meters. For the first time, the building-based construction method was adopted in the interior of Sun City. A large number of buildings with 8 floors and 5 meters in height were built, directly increasing the urban population carrying capacity to 10 unprecedentedly.Several parks have been built in the city, and various supporting facilities such as supermarkets, medical centers, and subways are also readily available.

Now, as long as you are not a young adult without parents, you can afford a house in the city.If you can't afford Sun City, you can always afford old houses in Human City and Earth City.

Those born through artificial wombs without the accumulation of their parents, with the support of various policies specially formulated by Zhao Changxing, can always afford a house as long as they work hard.

After Sun City, Zhao Changxing has no plans to build a large city for the time being, but puts all his energy on the industrial zone.

The previous open-air, fragmented and scattered industrial concentration method is being slowly abandoned by him.He intends to build specialized industrial concentration areas according to different industrial categories.

These industrial concentration areas will also adopt the construction method of urban type, and the internal working environment can directly sustain people's survival, and it should be as spacious as possible.The different concentrated areas are connected by railways, which can facilitate the flow of materials and personnel.

When this work is also completed, the time has come to the 216th year of the new calendar.Zhao Changxing didn't stop, and immediately started planning 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 Industry Department and the Science Department, Zhao Changxing said so.

During these years, I don't know how many heads of different departments have changed, so many that Zhao Changxing can hardly remember.But it doesn't really matter, what Zhao Changxing needs is someone who can undertake the 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 be economical, fast and convenient to complete the transportation of a large amount of materials.

"Yes, leader."

The heads of all departments agreed at the same time.

But when the space elevator was still in the initial demonstration stage, another sudden news disrupted Zhao Changxing's arrangement.

This message came from Xiaoxi.

"Captain, so far, I have received more than 1000 radio signals of unknown meaning from the direction of Cygnus. Because there are enough specimens, I have partially deciphered these messages."

Zhao Changxing's expression immediately became serious.

"Show me."

Xiaoxi’s principle of deciphering unknown information is to first set each individual waveform as an unknown number, such as X, X1, X2, A1, etc.In this way, a piece of information can be transformed into a string composed of many unknowns.

After that, it will first "guess" this piece of information, or the meaning of the sentence.For example, if you guess a sentence consisting of three waveforms of "X, B, F" as "1 is smaller than 2", but the sentence "F, B, X" appears in another sentence, then it is very easy. Obviously, it proved that the previous guess was wrong, and this meaning can be ruled out.

In the actual deciphering process, Xiaoxi will first give it tens of millions of guesses about the meaning of each sentence, and then use these guesses to cover the rest of the sentences.In this process, most of the guesses will be eliminated, and only a small part of the guesses can be kept.By repeating this, a deciphering result that is finally close to the truth can be obtained.

There is a prerequisite for deciphering in this way, that is, there must be a sufficient number of specimens.Only with enough specimens can the goal of eliminating wrong guesses be achieved.This is also the reason why Xiaoxi has not completed the preliminary deciphering until now.

Of course, in the process of deciphering, the possibility of meaningless sentences, sentences with wrong structures, etc. must also be taken into consideration.The real algorithm design is extremely complex, and can even be expanded into a professional book.Zhao Changxing doesn't know much about this, but he knows that Xiaoxi has this function.

At this moment, Xiaoxi's preliminary deciphering results were presented to Zhao Changxing.

In the deciphering result, there are a large number of characters ***XX", which is obviously the part that Xiaoxi failed to complete the deciphering. The following "()" 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 to be swallowed)."

"There is no value here for XXX (suspect noun)."

"Wandering XXX (unknown), you can stay here, we are XXXX (unknown)."

"Our XXX (suspected vehicle) was damaged XXX (description of degree of suspicion),"

"We are the last XXX (unknown) of XXX (suspect noun), we are XXX (unknown)."

……

Zhao Changxing looked serious, watching these deciphering results in silence for a long time.

This information seems to describe a "collective" that wandered and fled in space for an unknown number of years, lost an unknown amount of manpower and resources, and finally arrived at this place that was being swallowed by a black hole when it was about to perish. For another galaxy that is "collectively" worthless, I plan to linger here, recover my strength, and then start another escape.

"Could it be that another civilization has always existed near us? The survivors of that civilization are trying to rebuild civilization just like us..."

This information cannot determine the distance.But since "stars, black holes" are mentioned in the information, and the sun is being swallowed by that black hole at the moment, Zhao Changxing has no choice but to suspect that they are in the solar system, near the Sedna star.

"Concentrate all forces and launch a full search in the direction of Cygnus."

"Ok."

At this moment, human civilization already has considerable industrial strength, enough to build space telescopes of considerable precision.Under Zhao Changxing's promotion, in just a few years, as many as [-] new space telescopes entered space and joined the search.

As a result, it appeared in the fifth year.

"Captain, at a distance of 6300 million kilometers from us, I discovered a dwarf planet that humans have never discovered before. And...it has a certain atmosphere."

It is impossible for a dwarf planet so far away from the sun, so cold, and so tiny to have what is called an atmosphere in a macro sense.But now it has it, so the only explanation is that on it, some special, most likely the activities of intelligent life have caused this phenomenon.

Just like the heat released by human activities on Sedna Star, it will also lead to the sublimation of dry ice, solid gas, Thorin, etc., so that Sedna Star has a thin atmosphere for a short time.
