Blue Star Sea Diamond

Lango said: "It sounds interesting, have you seen such a signal?"

Cheng Ruomi said, "No, I'm just making an analogy."

Lango said: "So similar, like a signal from wisdom."

Cheng Ruomi said: "It is difficult for us to find a certain frequency or direction, and extract it from all the received bands."

Lango said: "Then how do you extract and do you want to do analysis?"

Cheng Ruomi said: "To be honest, I am in a mess. I am still looking for such a method, and this matter must be carried out in both directions. We have to guess what kind of signal the living body sends."

Lange said: "It stands to reason that numbers are unavoidable."

Cheng Ruomi said: "Yes, this is an important part."

Lango said: "He initially wanted to send a large number of signals, and for the signal itself, what is the probability that the aliens will use binary numbers?"

Cheng Ruomi said: "This will be very big. But there will also be life forms that use the base 3, because the use of the e base is the most efficient, and e is approximately equal to 2. 7, rounded to close to 3, so there is this Possibility, the possibility of balanced ternary is higher than that of binary, and the possibility of ternary or higher is very small and cannot be completely negated. Therefore, if you generally judge whether the source is a living body, you should first see if the signal is 2 The base is still 3 base."

Longo said: "Then it is either 2 or 3, then the scope can be narrowed, but other possibilities should be prevented."

Cheng Ruomi said, "That's right."

Lango said: "In addition, we need to explain a few things to b. If a is an earthling, earthlings prefer to show off their geometry, chemistry, music, etc., to show that they have a certain level of technology. This is one aspect. There is a model of the solar system in the Explorer of the Earthlings. Therefore, if aliens can receive that kind of disk, they must first study the solar system. According to the solar system, In order to identify where a life body will live. B needs to identify which direction a is coming from and how far away it is. In fact, it is easy to detect the signal of a in the entire sky on planet b. The direction of is definitely the strongest, so the direction with the strongest signal is the direction of the life body a."

Cheng Ruomi said: "The CD-ROM issued by Challenger No. 1 mentioned some of these situations. If there are any complications later, more patience is needed to analyze."

Longo said: "But what do you mean by the 1500 light-year signal?"

Cheng Ruomi said: "The antenna array I used detected a suspected valuable pulse signal. The format of this signal is cracked in multiple layers. It is definitely not natural to encrypt it. The content inside is a time signal in the front, and a time signal in the back. Bytes are repeated regularly. I named this character code H, and understood the content signal by myself. There are the following situations: 1. It may be a call for help, I am in danger or lack something. Resources; 2. It may be a greeting, and I want to find out if there are other lives besides myself. For me, it is unlikely that there is anything else, because in addition to the time signal, it is just a simple repeated code . But after a long time there were some seemingly repeated codes, and then a lot of repeated original H codes. I started to collect codes other than H codes and record them, and see if they are the same when they appear next time After about five times of collection, I was surprised to find that these five characters are roughly the same, but the details are different. I named the five characters J1, J2, J3, J4, J5. He began to speculate that these five codes should be the interpretation of the H code."

Lange said: "If the five-character code is to be interpreted, how can I understand the other party without knowing the other party's language?"

Cheng Ruomi said: "You need to understand linguistics. First of all, the signal does not need to be encrypted. If it is for help, it is likely to be a dead horse as a living horse doctor. If it is a rescuer, it can be saved. If it is harmful Then we will encounter a major disaster. So we began to use the current H and J languages ​​as the standard. Started to learn linguistics. Started to try to find the most frequent words in the signal, find the suspected first, second, and third person, and find Suspected punctuation marks, find some suspected information like numbers, find suspected verbs, find suspected words that may be calling for help."

Lango said: "Then have you responded?"

Cheng Ruomi said: "I started to manufacture and operate the same waveband transmitters, feedback some signals, and the time is based on the other party's standards."

Longo said: "If it is 1500 light years away, it will be received after 1500."

Cheng Ruomi said: "And there is no guarantee that they will not waste time sending or deciphering. It needs to be deciphered, analyzed, explained, and later. If the secondary signal is placed in the ranks of the candidates for sending the vital signal, then you can try to give back. , And then see if the other party’s signal will react to a certain extent because of my feedback."

Lange said: “If you want to communicate normally remotely, you must build on the basis that the communication can arrive in time, otherwise you will receive some long archaeological letters from each other.”

Cheng Ruomi laughed and said: "How to judge the strange suspected signal? Does the other party give back, or no feedback, or the signal is returned instead of a physical reaction? If it is really a signal of life, then there will always be a signal. Characteristics. Finding this kind of characteristics is not too complicated. After finding those characteristics, you can list them. Then, after you feed back the same level of signals, you can compare the changes in the signal characteristics of the other party. During the psychological contest, the other party should also analyze our signals in this way, and therefore compare and feedback our signals. We also need to feedback our own characteristic signals, and it takes a long time to capture such signals."

Lange said: "It seems that the graphic transformation of stock analysis has seen a life signal, how life grows, how to sleep, how to eat, how to die, I have researched, these are ridiculous digressions."

Cheng Ruomi said: "There is a basis for selecting the unnatural signals of life. Because no matter how the unnatural periodic signals are converted, although it is troublesome, it is enough, and that is a living body. We humans are being greatly affected. The various natural cycles fit and superimpose. If the signal is like that, I don’t care about any dynamic system, it is enough for a living body. Moreover, a living body, my definition is a living body and psychology, So we have the ability to ponder their psychology. If this is the case, we have to think that they have this ability. From this we have to think that we need to capture this signal, analyze this signal, and therefore we must continue to send this signal."

Lango said: "You can launch the following in that direction, add the other party's time, and then add the "I'll be here" signal."

Mi Pang was stunned by what the two people said, "Have you been doing this thing for many years?"

Cheng Ruomi said: "Yes, I have been doing it since my teacher Xia Ziqi. My teacher Xia Ziqi played for Kong Qiuming, and he was very good."
