Professor Shen Wei asked everyone to think about how to rescue scientists who were 15 billion light-years away, perhaps tens of millions of years ago. After the professor left, Xu Jiawei asked everyone to go back, leaving him alone on duty in the laboratory, Lin Shanshan said: "I know that you are not only on duty, but also to come up with a satisfactory plan, because in the laboratory, you think about problems while thinking, and you are more efficient in thinking about problems." ”

"Hehe, Shanshan, our disciples have characteristics in thinking about problems, and I am used to thinking while pacing. You unconsciously lie on the recliner at every critical moment, and the recliner in the unit seems to be specially equipped for you. Chen Jie held a teacup in his hand and drank and spoke slowly, Ma Biao is very good at execution, and he will do what the professor says. ”

"Jiawei, you have analyzed it well, then I will lie down in my chair, and I will leave it to you here. Lin Shanshan went out with a smile.

The next day, in the small conference room next to the laboratory, everyone including Professor Shen Wei talked about their opinions, and the meeting was very enthusiastic.

Xu Jiawei's speech is different from the past, this time he is no longer thoughtful, thinking and talking, obviously confident, he said: "I have five questions here that need to be clarified, namely the task, the carrier, the speed, the path and the goal. First of all, what is the task of our rescue this time, whether it is a simple rescue or another task, my opinion is to bring another task, the reason is: at the end of the day, it is urgent to say that it is not urgent or urgent, just as the professor said that saving people is like fighting fires, of course, it is a very urgent matter, but there is no substantial difference between the two of them coming back a few years earlier and a few years later, so it is not a very urgent matter. It is not easy for human beings to go to outer space, it takes a lot of cost, my suggestion is to take some other tasks, such as going to Proxima Centauri Planet 2 to see, I have long wanted to go up, this time I watched the video sent back by Tianhua Xiaozhi, there are suspected signs of life, I want to go up and investigate it in person, in order to get first-hand information. ”

Professor Shen Wei has always attached great importance to Xu Jiawei's point of view, after Xu Jiawei said the first point, he directly agreed to add other tasks when going to the rescue, but he agreed in principle whether it was directly down to the relevant planet, but he still had to make arguments to ensure that nothing went wrong.

"I know that the professor is thinking about my safety and the safety of this mission, and I think the necessary arguments are also needed. The second is the carrier. We currently have two kinds of spacecraft to choose from, one is a very mature 10 times the speed of light spaceship, and the other is the upcoming 100 times the speed of light spaceship, if from the perspective of technical reliability, you should choose 10 times, you can use it with confidence. 10 times the one-way journey takes 1.5 billion light years, 100 times it takes 150 million light years, I don't think there is much difference between these two numbers, because just by this speed, even if it is 150 million years, it will be 300 million years later, our generation of human beings will definitely be gone, and after a few generations, it may not be human beings, even if they are human beings, we can't predict the extent of their technological progress. Of course, I don't have any advice on what speed to use, just opinions. There is also space for the spaceship, 10 or 12 people, I recommend 12 people, because I don't know if the spaceship can come back, it is best to come back, we can also conduct research, it will definitely only be good for us, but we must be prepared not to come back, so we should reserve 2 people in the design, and try to be larger, we have not seen the previous generation of humans, in case they are particularly tall. ”

Professor Shen Wei nodded approvingly and said, "I will suggest to them, when designing, we must also consider that the two spaceships can dock, otherwise how can the two of them get in, this technical difficulty is very difficult, because I don't know what the other spaceship looks like, and how to get the interface is a problem." ”

Xu Jiawei continued: "What the professor said is extremely true. The third is velocity, you have to find the acceleration, otherwise you don't have to go out. We need the help of other teams in this area, such as how to use the gravitational pull of stars, the magnetic field of black holes to accelerate us, and the wormholes that have been talked about for more than a thousand years but still haven't been found, and I firmly believe that there is a mysterious gravitational source in the universe. The last two are just conjectures, and the first two I think we can take some risks and let other research institutions provide us with the specific locations and relevant information of stars and black holes with strong gravitational fields, because our research direction is not this, this is our weakness. ”

"This point of view is in my mind, I have done a good job in this area, all the information is with me, of course not for the end of the day, this time I just happened to be able to use it. After the meeting, we studied it together, and by the time we set off, we had already studied the information thoroughly. Professor Shen Wei said.

"The fourth is the path, the general direction of the path is east, but in the design, we must consider the combination of other tasks and acceleration factors, try to take the wrong road as little as possible, and there can be no deviation, even if it is a slight deviation, the difference is thousands of miles, let alone 15 billion light years away. I suspect that Sissy and the others may have been unable to find the source of gravity that led to this situation. Fifth, the target, because the target is too small to be located, but after reaching the end of the sky in the east, can we effectively capture the target? This is also a big problem, if we still can't find it in the end, then all the work done will be wasted. ”

After Xu Jiawei said these five points, the professor took the lead in applauding, and everyone agreed that he thought very completely, he said: "I immediately synthesized the opinions of the students and reported them to the National Astronomical Academy, and the specific plan was made by them, because we could not coordinate all aspects of people and things." Jia Wei spoke very well today, as for the fifth point to capture a small target, it should not be a big problem, our Ma Biao captured a celestial body with a diameter of less than 3 meters at a place of 1 billion light years, so far away can capture such a small celestial body, not to mention that he is looking for a spacecraft at the end of the sky that is likely to be larger than 3 meters. If this celestial body happens to be on the edge of the spacecraft, you can take a closer look, ah, haha. ”

"I'll try as hard as I can. Ma Biao said.

"Not as much as possible, but as necessary. The professor said.

"After that, when we contacted them, we tried to find out what their ship was made of and how they got in, and the structure of the ship was described in as much detail as possible, so that we were prepared when designing the interface between the ship and theirs. Ma Biao said.

"You're absolutely right, we must do our work meticulously and practically, and solve everything we can think of before we set off. The professor praised.

"Professor, it's not about how good your classmates' opinions are, but more importantly, your opinions, don't always say that the grades are ours. Lin Shanshan said.

"You little girl. "Professor Shen Wei is very satisfied with this team.

"No, Professor. Xu Jiawei said with a serious face.

"What's wrong?" the professor was taken aback. Everyone also expressed surprise at Xu Jiawei's words.

"Professor, you are partial, Ma Biao has only said one word about going to heaven so far, and you have wanted him to go up in your heart, but I have been thinking about it for so long, and you haven't made it clear. When Xu Jiawei said this, everyone laughed, including Xu Jiawei himself.

"It turned out to be for this, haha, this time is different from the past, there are many places, everyone has a chance, whether it is led by us or not, our team itself is studying this related content, and it must be a priority. There are 8 places, and if we take the lead, we will recruit a group of volunteers. Professor Shen Wei said, "Of course, having said that, it is not that you will be able to go if you want to go, but also consider your physical condition, knowledge structure, adaptability, psychological quality, etc., on the contrary, if you don't want to go, then it will definitely be, as long as you have a little idea of not wanting to go, even if you are extremely good in all aspects, you will respect your wishes and will not send you to heaven." ”

After Professor Shen Wei finished speaking, the students applauded warmly.

"I'll send the information I just said to the share right away, and you can read it now. The professor said.

"What about the video that Hua Xiaozhi sent that day?" Mr. Xu said.

Professor Shen Wei knew that the disciples' interest in Tianhua Xiaozhi had decreased, but he still did not allow him to give up, and in the face of Xu Jiawei's questioning, he replied directly: "Keep an eye on it." ”

"Do you want to see it?"

"How can you not look at it, the current focus is still on Proxima Centauri, the basic work to go to the end of the sky can be done now, whether it can be done, it is still unknown, we must not forget the main work because of this. Professor Shen Wei said.

"Okay. Xu Jiawei said.

"And. Space exploration within 100 light years should also be highly valued, and this time a spacecraft with 100 times the speed of light was built, even if it does not go to the end of the sky, exploration within 100 light years still has to go, which is an ironclad thing. ”

"Okay, let's listen to the professor's arrangement. Everyone said unanimously.

"Let's go our separate ways, I'm going to the office. The professor went to his office.

Xu Jiawei's interest is not in Tianhua Xiaozhi, nor in the galaxy within 100 light years, but directly in the 15 billion light year range. Since Professor Shen Wei made the rescue decision and reported it to the superior unit for approval, he firmly believes that he will be approved, and he will definitely be able to let himself go, the physical condition, knowledge structure, adaptability, psychological quality, etc., the professor said, none of them do not meet the requirements, if there is one that does not meet the original professor, he will not let him enter the team. The only thing that will "drag him back" is the family, his father is a geography teacher, and space exploration is also his point of interest, although he will not agree to go to space, but the opposition will not be too strong, his mother is his biggest resistance, she will not agree with him to take this risk, how to convince his mother when the time comes? Mom is a person who does not listen to opinions, and it is not easy to get her to agree. Alas, I will talk about it later, the ship will go straight to the bridge gate, there will always be a way to solve it, first do the things in front of him well, he must pay close attention to study and research, and wait for the professor to come back from a business trip, and tell the specific actions one by one, so that the professor will be pleasantly surprised. The professor went out for a long time this time, it took a month, mainly to finalize the rescue plan, spaceship design drawings and other things that Xu Jiawei did not know. On the side of the laboratory, when he went out, he had already given a few instructions to Tianhua Xiaozhi, and the main task during this time was to receive. At the end of the day, the professor has designated Lin Shanshan to do it, so that he has more time to do what he wants to do. In fact, he also found that the other three students were also making preparations, but fortunately, there were 8 places this time, and everyone did not have to compete. Xu Jiawei studied the materials sent by the professor in the sharing article by article, studied the gravitational attraction of related stars and black holes, and listed many problems that he did not understand.

Xu Jiawei was nervous about work, and his younger brother Xu Jiaxuan called.
