Li Yu is installing the Linear Collider with the assistance of the robot, and thanks to the use of force field acceleration and constant superconducting materials, the Linear Collider can achieve only 30 meters, and can accelerate to 99.9999999999% of the speed of light in just a dozen meters.

Miniaturization means the integration of more components, and the assistance of robots can greatly reduce Li Yu's workload.

Lin Wanbai was assisting on the side, more in learning.

"Li Yu, do you value that Fang Qianmo very much? She also went to Tokai to attend her company's opening ceremony. Lin Wanbai took the opportunity to ask Li Yu this question that had been hidden in her heart for several days.

"Of course, Fang Qianmo is also a genius like us, our type of people are relatively rare in this world, and it is one to be able to win one as a friend." Li Yu explained to Fang Qianmo his concept of choosing friends.

Fang Qianmo was a little incomprehensible, "But I don't think Fang Qianmo is as genius as you say!" ”

"This, Fang Qianmo has gone the wrong way, she has put more energy into business and family, and she has not invested enough energy in scientific research, so she has less achievements in scientific research. But during the time I worked with her at school, I found out that she was still very talented. ”

"But I believe that one day she will wake up, and she will find that scientific research is the ultimate destination of her life."

Lin Wanbai understood a little, "Just like I wasted my energy in anime and TV series before?" I also feel that wasting time is a pain and a stain on my life. ”

Li Yu snorted, and the follow-up began to concentrate on work.

After the crystal grows, Li Yu transformed and upgraded the space probe, and Li Yu reopened the space probe.

Li Yu strengthened the detection of the signal, so when the space probe was activated, the space wave signal was clearly received. It can be seen that this signal is a long-wave signal, so it took Li Yu and Lin Wanbai three days to collect the space wave signal completely.

In order to ensure the integrity and reliability of the data, when the data of this signal was repeated five times, Li Yu stopped receiving the signal and analyzed the data of this signal with Lin Wanbai.

"Huh! This is... Is this kind of signal wave really not generated by the movement of space and celestial bodies, but by artificial space waves and amplitude modulation space waves containing information after signal modulation? Li Yu said a little disgraced.

Space exists in the form of energy, and all things in the universe interact with it to produce secondary energy waves and fields of various frequencies, which is the external manifestation of space energy, and Li Yu studies space through this secondary energy wave and field.

It's not that Li Yu doesn't want to study space directly, it's that the equipment and materials limit Li Yu's ability to study space, and he can't directly study space.

So Li Yu doesn't have the idea of using space waves as a communication carrier now, because it doesn't make sense. Make a space wave communicator and contact whom?

The wave that Lin Wanbai found that was filtered as clutter turned out to be an artificially modulated signal wave, which is of great significance. Although the content contained in this signal wave has not yet been deciphered, based on the existence of this signal wave itself, Li Yu and Lin Wanbai can deduce a lot of information.

The existence of aliens can be determined in the first place. Secondly, the technological level of aliens is not ordinarily high, and their communication methods have been based on space.

The civilization level of this alien must be much higher than that of the earth, at least, human beings have not yet left the solar system, and have not even carried out colonization operations in the solar system.

Human beings themselves are still mainly based on radio, and at most the laboratory has black technologies such as quantum communication, but compared with space wave communication, it is not a level of technology at all.

Li Yu forgot about his unexpected example, the level of civilization on the earth is not high, and he is not in touch with the mysteries of space?

Is Earth ready for contact with extraterrestrial civilizations? Or is it still such an advanced civilization? Li Yu and Lin Wanbai have no bottom in their hearts.

Now, they have to think about it because aliens have appeared and they can't turn a blind eye.

Li Yu didn't have the idea of announcing this matter in his mind at all, and Lin Wanbai didn't have it. In the hearts of the two, apart from them, no one else on Earth has this ability to communicate with aliens.

After hesitating for a while, Li Yu and Lin Wanbai glanced at each other, they must contact! This is an opportunity, miss this opportunity, and don't know when you will be in contact with aliens.

Now that the decision is made, Li Yu has to think about how to communicate with alien civilizations.

Communication is the key to communication between the two civilizations. According to Li Yu and Lin Wanbai's speculation, the communication methods within each civilization are very different, let's just say that there are thousands of languages on the small earth.

So what should be the communication between civilizations when they first meet each other?

Li Yu didn't know, and Lin Wanbai had no clue. They had never thought about it before.

Li Yu let go of the thousands of thoughts in his heart and asked Bu Wei to try to decipher the signal contained in this space wave, but as expected, Xiao Wei failed, and the information extracted by Xiao Wei from the signal wave was garbled, and Xiao Wei couldn't identify the information in it.

According to the amount of information contained in the signal, combined with Xiao Wei's analysis, Li Yu believes that the information contained in this space wave should be mainly text information, supplemented by a small amount of picture information.

Based on its own signal form, Li Yu speculated that if it contained video content, this signal wave should be more complex.

Faced with this result, Li Yu and Lin Wanbai had to seriously think about how the two different civilizations could communicate.

This proposition is relatively big, and Li Yurang let go of Xiao Wei's permission, allowing her to move freely on the Internet to find answers in this regard. And he and Lin Wanbai kept putting forward hypotheses, verifying, proposing, verifying, and verifying in the laboratory, and so on.

For this work, Li Yu stopped all the work that could be stopped in the laboratory.

In the end, Li Yu found the most likely way, using mathematics. Mathematician Francis Goldon pointed out that mathematics is the core of civilization, and if language can be expressed mathematically, it is most acceptable to aliens. The rigor and logic of mathematics make it one of the possibilities to communicate in language.

The rules of the entire universe are consistent, and the laws of nature are universal in the universe. The knowledge obtained from the exploration of the universe may be expressed differently by each civilization, but they will eventually converge on a single point, which is the law of the universe itself.

Thinking about it from this perspective, if a civilization wants to communicate with another civilization, if it uses mathematics as the core, then the signals it sends should contain the dictionary of its own civilization written by its own civilization according to the laws of the universe it knows.

For example, elements in a contemporaneous table can be mathematically expressed.

The degree of civilization that emits space wave signals should be able to recognize this problem, so from this direction, it is not a problem to decipher the signal, but only a matter of time.

Of course, if this signal is only communication within civilizations, there is a high probability that it does not contain a dictionary. However, how do you know if you don't try?

Of course, Lin Wanbai supported Li Yu's opinion, and the first thing the two of them had to do was to compile a set of dictionaries of earth civilization, and then translate them with each other's comparisons.

Compiling a dictionary is not an easy task, but for Li Yu and Lin Wanbai, it is not an impossible task.

The mathematical expression of the dictionary, Li Yu chose binary. Binary has many advantages, which are more suitable for the situation faced by Li Yu. Human beings themselves are accustomed to the decimal system, and it is human beings who are more accustomed to the decimal system because they have ten fingers.

With the direction, the speed of compiling the dictionary is still quite fast, and it took half a month for Li Yu and Lin Wanbai to divide and cooperate to compile the dictionary. Li Yu was in charge of the trunk of the dictionary, Lin Wanbai added the content, and finally they checked it together.

Of course, the language of the dictionary is based on Chinese characters. Although binary is more suitable for Latin English, who made the writers Li Yu and Lin Wanbai. Chinese characters are the mainstay, supplemented by English, mainly Latin characters are more convenient in the expression of formula symbols, and Li Yu and Lin Wanbai are more accustomed to it.

In the process of compiling the dictionary, once Lin Wanbai suddenly came over with a terminal and said happily: "Li Yu, look at it, I have drawn a lot of aliens, guess the alien who seems to be sending the signal this time." ”

Li Yu curiously took the terminal in Lin Wanbai's hand, and saw more than a dozen strange-looking monsters painted on it. Lin Wan's unbridled imagination made Li Yu stunned: This blade queen is okay, but why add nine tails? The flower fairy has become a blue fairy, and her wings have been replaced with bats, so she doesn't look like an avatar. These two are at least human-shaped, and the ones behind them are almost a combination of various animals and plants, Li Yu complained in his heart, how can a girl like these monsters.

This is an episode, and it also reflects a certain hidden worry in Li Yu and Lin Wanbai's hearts, are aliens friendly?

Worried that it would not stop a scientist's vigorous thirst for knowledge, the dictionary was quickly written, and after checking it a few times, Li Yu entered the words into Xiao Wei's database and asked her to start deciphering the signal according to this dictionary.

With Xiao Wei's computing speed, it also took two days to decipher the information contained in the space wave.

"Hello!"

Just such a short sentence.

When Xiao Wei showed this result in front of Li Yu and Lin Wanbai, they rubbed their eyes at the same time, how could this be?

Li Yu and Lin Wanbai have made a lot of assumptions, for example, this signal is the contact signal between the aliens exploring outside and the mother planet; a communication signal in a remote area of an alien; The extraterrestrial alliance of advanced civilizations broadcasts in the universe, used to guide low-level civilizations, and other conjectures.

I just didn't expect that the information contained in this signal seems to be the same as the first time humans make a telephone, and they can carefully make the first hello through the phone line!

It's not scientific! Li Yu and Lin Wanbai looked at each other.
