They inadvertently mentioned the disaster, and Professor Shen Wei said: "We should not be satisfied with the current level of science and technology and observation ability, but should think and talk openly." Garvid has a point, prehistoric humans may have gone extinct for some reason of their own. Just like 900 years ago, my generation almost went extinct. ”

"Professor, can we reply to this message?" Lin Shanshan asked.

"Not for now. First, we don't know the situation, is it sent to people on the earth? We hastily reply that maybe they received it wrongly and it would cause disaster. Second, even if it is sent to earthlings, we don't know what their situation is, and we can't reply. 3. I don't know when this message was sent, maybe tens of thousands of years ago, and there is no point in replying today. Observe and observe first and see if there is a follow-up. Professor Shen Wei said.

"Okay. Lin Shanshan said.

Professor Shen Wei then made three decisions: first, to isolate the electronic signals of the two walls, in case one of them is attacked, it will not affect the other, and then to re-receive the video information from "Tianhua-1"; second, he should immediately go to the National Academy of Astronomical Sciences to report this information from 15 billion light-years ago to the higher authorities, and try to have the Academy of Astronomical Sciences take the lead in organizing expert discussions and come up with authoritative opinions as soon as possible; third, during the time that Professor Shen Wei left the laboratory, the disciples continued to keep an eye on "Tianhua-1" And the news from 15 billion years ago, the laboratory work was temporarily handed over to Xu Jiawei.

Xu Jiawei is Professor Shen Wei's most proud disciple, although he is less than 30 years old, his academic level is already well-known in the domestic astronomical community. He said to Professor Shen Wei, "But Tianhua Xiaozhi only listens to your instructions, what if there is any request?"

"I've been here for a maximum of half a month, and Tianhua Xiaozhi still has two instructions to complete, one is to take a map of Proxima Centauri's close-up planetary system and calculate a series of data, and another is to fly to the middle of the three substars to calculate a series of data. These two tasks could not be completed in less than a month. So don't worry about it begging for instructions, ha. Professor Shen Wei said with a smile.

"Well, please rest assured, Professor, I promise to do a good job. Xu Jiawei said.

"You continue to discuss, and I will listen to a report on the results of your discussion when I return. Shen Wei went out after explaining his work.

Soon after Professor Shen Wei left, technician Ma Biao separated the electronic transceiver system on the two walls, and the video information from the "Tianhua No. 1" was restored on the wall.

This is a young team, the eldest Ma Biao is only 33 years old, and the youngest Lin Shanshan is only 27 years old, they are the top young talents selected by Professor Shen Wei from all over the country, and the research direction is to find energy in outer space - not to find a place to live, that is the task of another team. The earth's energy will run out one day, and since the oil was drained 900 years ago, people have adopted combustible ice as a new source of energy. At a World Science and Technology Conference held 400 years ago, Chinese scientists resolutely put forward a topic -- "looking for energy outside the earth", he said at the meeting: "We can't keep our eyes on the earth, because the reason why the earth is the earth is because it is composed of many reasonable substances, and if we consume its reasonable substances, it will definitely take revenge on us human beings." Before it is possible to immigrate to other planets, we will act in unison as soon as possible to find energy sources outside the planet. Our country has already made some bold and useful explorations in this regard, and I might as well decipher it here, we captured and brought back an asteroid with a diameter of about 100 meters in the asteroid belt outside Mars, and through laboratory research, it has been confirmed that the material extracted from it can withstand flying at the speed of light, which cannot be found on Earth. What kind of concept is this? This shows that the asteroid belt has a lot of materials that we need, and the asteroid carries so much material, why don't we mine it for our own use? This kills two birds with one stone, which not only provides us with a steady stream of energy, but also eliminates the consequences of collisions. "Scientists from all over the world are very interested in China's initiative, after the arrogant country M was destroyed by the all-round intelligent man designed and manufactured by itself, the world is peaceful, in such a big issue related to the survival of the earth and the continuation of mankind, scientists are in unison, and actively respond to the initiative of Chinese scientists, believing that as long as this achievement becomes a reality, human beings no longer need to mine energy on the earth, let alone move, man and nature will be extremely harmonious, the universe is so big, there is an inexhaustible source of energy. At the meeting, it was quickly agreed that the wisdom of the world would first create a local living environment on Mars, and then mine the asteroids nearby.

Staring at the two walls like this is a bit boring, Lin Shanshan said: "Let's find something to talk about, you say, what will be the research results of the experts when the professor goes to the National Astronomical Academy this time?"

Ma Biao said: "The result is nothing more than two kinds, contact, no contact......"

Lin Shanshan said: "Isn't it the same as not saying it?"

"In fact, the professor's voice is very strong, and the professor basically has the final say whether he is connected or not. Ma Biao said.

Lin Shanshan said: "Xu Jiawei, you know the professor's mind best, you can talk about it." ”

Xu Jiawei smiled and said, "The professor asked us to discuss the next step, and as a result, we discussed the professor's ideas. ”

"The professor only asked us to discuss, not to say what we were asked to discuss, and our discussion of the professor's ideas is also a kind of discussion, haha. Chen Jie, who was sitting on the side and drinking tea, said.

"Okay, everyone said to discuss the professor's idea, so let's discuss this first. Xu Jiawei also wanted to break the dull atmosphere and drive away the boredom of the laboratory, saying, "I'll say it first, and you have to say it too." I guess the professor's first feeling is that he wants to get in touch, and the reasons are, first, have you noticed, he was very excited when he first saw this message, and then he calmed down, and then he actually began to analyze it in his heart; second, he wanted us to let go, he wanted to hear our point of view, he wanted to get some inspiration from us, our professor has always been very modest, never imposed his own point of view on us, if he wanted to give up contact, he didn't need to listen to us so much, and he himself didn't need to make three decisions not to contact for the time being, just deny it; third, so anxious to go out and report, research, which means that he advocates connection. ”

"Then does he want to find a reason to get in touch?" Mr. Chen said.

"No, he is looking for reasons why he can't be contacted, only to find out the reasons why he can't be contacted, and then deny them one by one, and the rest is to connect. Xu Jiawei said.

"I agree. The professor's style is like this, using counter-evidence to prove his point of view. Especially on such a big issue, even if there is a reason why it cannot be contacted, the professor will not agree to contact. Lin Shanshan said.

"That's right, at that time, I said that I would replace Tianhua Xiaozhi, and the professor used such a counter-evidence method to deny a reason why I couldn't go, even if I had thousands of reasons to go, he wouldn't agree to let me go. Xu Jiawei sighed.

"Then, Jia Wei, what about your opinion? to contact or not to contact?" Lin Shanshan said.

"Contact, not only contact, I also want to fly over!"

"Huh?!"

"What's so surprising about this?" Xu Jiawei said, "I believe this information is true, that spaceship must be there, if people can go, why can't we go?"

"Maybe it doesn't take 15 billion light years for other people's planets to get there, and there are other people's technology that is faster than ours, and we are only 10 times the speed of light that we are mature now, and we can only reach it in 1.5 billion years at this rate, not to mention whether people are still waiting for you in this position after 1.5 billion years, can you live for 1.5 billion years?" Lin Shanshan said.

"Your point of view has great limitations, first, you only look at the problem from the standpoint of the earth, living on the earth, human life expectancy is limited, once out of the earth, living in space in a state of superluminal speed, maybe people will stop growing and developing, so that people's life expectancy will not be extended? Second, the experiment of 100 times the speed of light is also successful?" Xu Jiawei said optimistically.

"100 times the speed of light is still in the laboratory, even if it is immediately applied, it will take 150 million light years for you to go there one way, and when you come back, I don't know if the earth exists, and even if it exists, human beings may also die out, in case the new generation of creatures is not a person in the current sense, maybe people will treat you as an extraterrestrial visitor, locked in the laboratory for future new creatures for experiments. If the earth is gone, then you will become a ghost wandering in space forever. Ha ha. Lin Shanshan teased.

"It's reasonable, it's reasonable, haha, thank you for the reminder, otherwise a thought will become a hatred for eternity. Xu Jiawei also joked.

Chen Jie took a sip of tea and said slowly: "In my opinion, it doesn't hurt to get in touch, what if the other party has a faster path to provide us? ”

"If this message was just passing by, and not sent to us, wouldn't it be a disruption to people's normal communication by replying rashly. Ma Biao said.

"Ma Biao, is it possible that the message we sent makes people unable to figure out our specific location?" Mr. Xu said.

"Why?"

"If it's a malicious message, and someone is testing our location and then attacking us, then we're doomed. I'm very disgusted that a thousand years ago, our ancestors told the extraterrestrial beings about the location of the Earth through what Voyager 2 carried, which is not a good thing, and it may bring disaster to the Earth. Xu Jiawei said.

"Technically. Ma Biao said.

"Why is it possible that this is a malicious message, I think so, since people can send text messages, why not send video and audio at the same time?" Xu Jiawei said.

Lin Shanshan said: "Jia Wei, I think you are becoming more and more like a professor, and you have thought about some things that seem unnecessary and impossible so thoroughly. Hearing you say this, I also think it's a little weird, and my opinion is not in a hurry, and I will send it after coming up with a foolproof plan to ensure that it is correct, but in the end I still agree to contact, but this process must be cautious. ”

Xu Jiawei said happily: "Then our opinions are unanimous, and the general direction is to agree to contact, but there is no hurry." ”

"Not true. Lin Shanshan said.
