Professor Shen Wei saw that Lin Shanshan had something to say, but he only started and immediately stopped and said, "Shanshan, if you have any ideas, say it boldly." ”

Lin Shanshan said: "Actually, I haven't thought about it yet, I won't know the answer until I find them, according to my guess, they originally designed to be the fastest for decades - that is, the people who sent them out can see them come back in their lifetime, even if they can't see them come back, they will also see them reach their destination, and the limit will be too late to let the younger generation of their peers see them back." Lin Shanshan said.

"Yes, is it normal for humans to be seen by at least a generation later than them? Fortunately, there is a later generation, and fortunately the later generation is still human, not for other creatures, and they happen to be able to read each other's information, otherwise they will never come back. There must be something wrong with this, and they must be flying faster than we can imagine, perhaps comparable to the speed of information exchange. For some reason, the flight speed was far from the requirements of the design, which caused the current situation. Xu Jiawei said.

Shen Wei admired Xu Jiawei's analysis and encouraged him to continue.

Xu Jiawei said: "There may be two reasons, one is that the technology is not mature enough to be used, and flying in space cannot achieve the experimental effect, and the other is that there are uncontrollable reasons encountered in outer space." Outer space travel is still very risky, after all, it is too far, measured in light years, and there is a hundred million words added to it, which is not as mature as our travel in the solar system. ”

"Hmph, then you still want to go out, the last time Proxima Centauri didn't let you go, I'm still haunted by it. Professor Shen Wei said.

"Two different things, two different things. It can't be said that if there is a risk, you can't go, I don't go to hell, who goes to hell. No matter how much risk there is ahead, I will go for it, the two at the end of the sky are my examples, even if there is a fate like theirs, I think it is worth it, after all, I have lived a generation more than humans, haha. When the time comes, I'll tell them that I'm millions or tens of millions of years old. Xu Jiawei said.

"I'll put this matter aside for a while and wait for news in 20 days. Now let's take a look at Tianhua Xiaozhi's performance, it has arrived in the large planetary system, last time it stayed in the middle of the three star stars for a while, sent back a lot of data, and also saw the planetary maps of the other two stars, and will do research when you have time. Professor Shen Wei said, "You see, there are too many planets here to count, and there are planetary moons, and a master like Tianhua Xiaozhi has not yet calculated the data." At a cursory glance, it is really a bunch of garbled codes, the orbits of the planets, if you don't look carefully, it seems to be irregular, and you will accidentally bump into it, and the way of rotation is also varied, and the preliminary judgment is related to the gravitational interaction of the three stars. ”

On the wall, the video transmitted back by "Tianhua-1", the large planetary system is like a bunch of garbled codes, irregularly, because it is taken at close range, the planets with atmospheres and the planets without atmospheres are clear at a glance. Professor Shen Wei asked everyone's attention to focus on terrestrial planets, because the possibility of gas planets having living organisms is extremely low, and the reserves of resources will not be greater than terrestrial planets.

"With so many planets, it feels like there's nowhere to start. Xu Jiawei said.

Professor Shen Wei faintly felt that the emotions of the disciples were a little wrong, they were not in the state at all, they were infinitely interested in discovering new planets before, even when they saw the planetary system of Proxima Centauri not long ago, they were very excited, they looked very carefully, they were also very involved in the discussion, and they were able to quickly put forward their opinions. What's going on today?

"Professor: I'm a little sleepy, can I rest. Lin Shanshan said.

Shen Wei looked at everyone's appearance, maybe he was tired, so he agreed, and said, "You all go out for activities, and I will be on duty here." ”

The disciples were not polite and went out immediately. After all, their concentration is not as strong as Professor Shen Wei, since the relationship with the end of the sky has been strengthened, their interest in "Tianhua No. 1" has been greatly reduced, if it were not for the professor's urging, their minds would all be on the end of the sky.

Xu Jiawei searched for stars within 100 light years. When he calmed down, he thought about what he hadn't finished thinking about that day, and he wanted Xixi and Nannan to go out to investigate, and if they went for thousands of years, it was certainly not the original intention of sending them, and where would the mistake in the middle be? Could it really be that there was a problem with the spaceship itself that he had guessed that day, and that the technology was not mature enough to go up? This possibility is almost none, and their technology is so advanced that there will not be such a low-level mistake. Then it is especially likely to be caused by uncontrollable and unpredictable reasons in space, where there are not only inexhaustible substances, but also mysteries that cannot be solved by endless research. From the perspective of our generation, their most fatal mistake is to let the west, south, south and south fall asleep, if they don't sleep, the situation will definitely be different, keep in touch at any time, and solve any problems at any time. So why let them go to sleep? Originally, it was most reasonable for two people to go up, so that one person could always stay awake and ensure the normal operation of the ship. I don't know if I go up on my own in the future, I must learn this lesson. Their ship must be fast, and the plan they designed must be back decades at most, otherwise it doesn't make sense. Why are they so fast? Is it the speed of their own spacecraft, or is it a clever borrowing of the mysterious gravitational pull of space to accelerate? The conjecture should be both, the speed of the spacecraft itself is faster than ours, far exceeding 100 times the speed of light, but they still want to use the mysterious gravity in space to accelerate, but due to unpredictable reasons, plus the two of them fell asleep and could not wake up the operation, they could not control it in the laboratory, and deviated from the original design route, resulting in the spacecraft unable to accelerate, and could only watch it fly in the universe at a normal speed, and then also had a premonition that there would be no goodbye. It must be so, definitely.

Xu Jiawei ran to Professor Shen Wei's office and reported the idea to the professor, who praised Xu Jiawei and encouraged him to continue thinking about the idea, and maybe solve a mystery. At the same time, these ideas are very useful and can be taken into account on the next manned excursion.

A few days later, the news came at the end of the day, which was very bad news, Xixi and Nannan said that according to the original design, they could not come back on their own, the spacecraft was controlled by the laboratory, and after the mission was completed, the laboratory automatically recalled them. Now that their generation is gone, then they will never come back. It could be seen that they were very frustrated, and they did not know the specific task of going here, so they said that they would be given it when they reached it.

Although sacrifice can happen at any time in the exploration of the scientific road, and everyone in this team is ready to sacrifice for science, the mood is still tragic in the face of the sacrifices of their predecessors. More than 1,000 years ago, the mysterious disappearance of Chinese scientist Peng Jiamu during an expedition to Lop Nur became a major event that shocked the scientific community at that time. In this way, there are no people in life and no corpses in death, not to mention the people at that time, now that a thousand years have passed, they are still so worried when they think about it. It is also recorded in the history books that when Apollo landed on the moon, there was almost an accident, there was no return, and the ground contact station almost closed the contact channel, and it is said that he could not bear to see the earthlings slowly dying on the moon.

What is happening in front of us is a very serious problem, two human lives, even though they are the last generation of human beings. But 15 billion light-years away, there is no way to rescue it with the current technology. I really want to save the powerless, and if I don't save my heart, what should I do?

It can be seen that Professor Shen Wei, who has always been calm, also looks a little uneasy at the moment.

"What about the professor, let's go to the rescue?" Xu Jiawei said.

"Technically, we're not capable yet, but I'll be there if we were to save it. Ma Biao said.

"How to save? With our current ability, we can't save each other at all, and we won't even reach the end of the day. Chen Jie said.

Seeing that the disciples were discussing, Professor Shen Wei said: "Students, I don't think there is any need to discuss the question of whether to save or not, saving is definitely to be saved, two lives, not to mention two scientists of the previous generation of human beings, as the saying goes, pity each other, if we are in such an environment, people will spare no effort to rescue." The question now is how to save it, and it is certainly unrealistic to save it at 100 times our speed of light years, and we have to think of another way. I am ready to send a message to the world and mobilize the whole world to rescue me. ”

"Professor, before we make an announcement to the world, do we have an idea of what kind of help we want people to provide, otherwise we will not be the one who will take the lead. Xu Jiawei said.

"Hmph, I don't care who the leader is, as long as I can rescue him, it's a victory, even if we are a small supporting role, I'm willing. However, I agree with what you said about thinking of an idea, no matter who takes the lead in the rescue, it is incumbent on us to come up with an idea. Professor Shen Wei said solemnly. It was rare for the disciples to see the professor look so serious.

After a moment of silence, Professor Shen Wei continued: "We immediately sent a message back to tell them that we had learned about their situation, and we were trying to pick them up and ask them to keep in touch, at least once a day, regardless of whether there was a new situation." You can do this work. ”

"Yes. Lin Shanshan said.

"Students, we all opened our minds and thought about how to rescue. One day, that is, this time tomorrow, we will focus on the discussion that saving people is like fighting a fire, the sooner the better. Everyone comes up with a solution, even if it's an idea, think completely open, don't limit yourself to the existing conditions, and don't consider whether the plan is complete. ”

"Professor, you are a little anxious, please calm down, otherwise it will affect your decision-making. Xu Jiawei said with a smile.

"Oh. Professor Shen Wei returned to his office.

"Let's go, let's go, you all go back to the office, I'll be on duty here. Xu Jiawei said.

"You want to sit here alone?"

"What's wrong, Shanshan?"
