"You're welcome. Not far from it is the tomb of Tianle's father, and later the joint tomb of Ji Renrui and his wife, I have always paid tribute to the dead of the three families at the same time. Three times a year: Qingming, October 1, and Spring Festival. She paused, frowned, and said, "Damn, I can't even remember the name of Tianle's own father, because there is no stone tablet or name on his grave either." After all, I'm 100 years old, and my memory is not good. Can you tell you my name? ”

"Absolutely. My name is He Ming, and I am He Xing's widow. ”

"He Ming, He Xing, I won't forget it this time." After saying these words, the two were silent. Yu Leshui didn't ask him what he was doing, he thought he would say it himself. Sure enough, the man spoke again:

"Forgive me for coming here late at night, I wanted to revisit my father's path and experience his state of mind at that time. Ms. Fish, I won't be as murderous as my father did. I'm here to tell you publicly that I will raise the anti-flag against Chu Tianle, a saint that everyone looks up to. ”

Yu Leshui suddenly realized that he remembered the name He Xing, the leader of a secret organization whose purpose was to oppose the "Sleeping Beauty" plan. The Friends of Joy and the United Nations had long been aware of the information, but had not taken any action. Because both organizations feel that in order to make the "Sleeping Beauty" plan as safe as possible, the existence of an anti-party organization is not harmful, and even beneficial. The police secretly learned about the members of this organization, including its leader He Xing, and believed that they were not ****, but down-to-earth intellectuals, and their opposition was out of a sense of responsibility to mankind. Therefore, the police did not embarrass them, but secretly continued to pay attention. She said calmly:

"Chu Tianle is by no means a saint. But I'd love to hear why you're against him. ”

"He predicted a catastrophe of the collapse of the human intellect, but purely using reasoning and analogy, without any empirical evidence. Now, human civilization is about to take the initiative to stop because of the order of one person, and return to the era of ignorance of slash-and-burn farming, and even the age of barbarism when wool and blood are drunk, which is ridiculous! In particular, this saint is now only a head, and he is imprisoned alone in a cell of neutron-like matter, and he may have been a madman for a long time! All those who agree to give him the power of human life and death are also insane! You might say that his orders must be countersigned by one and carried out by another, both of whom have the right of veto; The earth side can also be hacked in reverse. But these are too child's protections, if he has evil intentions, he can find a way to bypass these three protections and set back the earth's civilization by 10,000 years in an instant. He added, "I am a senior director of the China branch of the United Nations 'Sleeping Beauty' programme. As an insider, I understand these dangers better than anyone else. ”

After he finished speaking, Yu Leshui was silent for a while, and said softly: "I just finished talking to my husband not long ago. As is customary, we're going to take a quiz on the other person's mental state - no, don't say it's child's play, please be patient with me. But I didn't test his intelligence today, but I deliberately mentioned to him my affair with another man. You know why? ”

The other looked at her and did not answer.

"I deliberately tested his mental state with the most sensitive questions. I'm not saying that he's already had any dangerous changes, no, nothing so far, but it's always good to be cautious. You see, I have the same concerns as you, so the two of us are not hostile, but allies. ”

He Ming didn't expect Chu's loving wife to have such an attitude, and he was stunned for a while.

"We can do this together. Considering my advanced age and the fact that I have few days left, I intend to entrust you with the burden now. I have just finished writing my memoir, "A Hundred Years of Collecting Shellfish", which is a detailed account of our lives, which should be of great help to understanding his character as a person. I want to give it to you for safekeeping and use, so that you can establish a precise fixed coordinate system to compare his personality and behavior for any changes or deviations. Are you willing to accept it? ”

She turned and picked up the leather-covered journal from her desk. He Ming hesitated for a moment and then said, "Thank you." I accept. ”

Yu Leshui's attitude turned serious: "But you must be objective and fair in doing this. Frankly, from what you just said, I smell some extremism, which may be inherited from your father. I also smell the resentment that arises from your father's tragedy. These are unacceptable distractions for the mission you are trying to accomplish, and they must be completely discarded. Can you do it? ”

He Ming thought for a moment and said resolutely, "I can." ”

"Okay, let's shake hands, even if it's a verbal agreement."

The two shook hands and looked at each other, but neither spoke. He Ming took the diary and put it in his arms. Yu Leshui said: "You can go to the house to rest first, and when the morning comes, I will call a helicopter to see you off." If you don't want to alarm others, it's okay, the babysitter will be back tomorrow morning and can see you off with an aerial electric car. He Ming shook his head and said, "I still walk down the mountain like when I came, I just want to experience this state of mind." He said goodbye, and the sound of footsteps faded into the night.

Yu Leshui watched him go away, and at this time, the telephone rang in the house. She hurried back to the house and turned on the phone, it was UN Secretary-General Croswell. On the screen he says:

"Fish, we agreed in advance, tomorrow I will go to your place to celebrate your birthday. But I have just heard a piece of news, and I would like to tell you in advance, that in that case, I may hear a wise opinion tomorrow when I see you. It's a shame to say that in the thirty-three years since Mr. Chu left the earth, human society has been busy defending against the disaster of intellectual collapse, and there is almost no decent scientific exploration. You know, over the years, only one Mach 100 million spacecraft, the Limbo, started its test flight a month ago and just returned to Earth today. ”

"Is there any news from Willow Leaves? Or Ji Jichang or the other two fleets? ”

"Ha, you can't wait like me! Let me tell you, it's about Noah. One hundred and ten light-years away from the solar system, Limbo picked up a drifting bottle that they had cast. The thing was constantly emitting radio waves, but if it hadn't happened to be touched by the Limbo, it would have been a hundred years before Earth could have received the message. ”

He showed the actual bottle on the phone screen. The so-called drifting bottle is not bottle-shaped, but a mirror-like ball, which is not much bigger than a basketball compared to the human hand next to it. An antenna sticks out from the top and bottom of the ball. The power plant is not visible, perhaps hidden within the sphere. "What's the content? Good news or bad news? ”

The other party's answer was a little hesitant, "It's neutral." You might as well take a guess and let your imagination run wild! ”

Yu Leshui first thought of the joke that Ji Renrui had said, and asked with a smile: "Angel married an alien daughter-in-law?" ”

"Your conjecture is not science fiction. No, the contents of the letter should be considered a major theoretical breakthrough, but - I don't know if it's a blessing or a curse. ”

With the help of the screen, he showed the main content of the letter. Before the end, he said: "These messages were immediately notified to the 'Wild Goose Whistle', which was only less than fifty light minutes away from the earth at that time, so Mr. Chu Tianle already knew the details at this time. With that, the Secretary-General said goodnight and hung up.

Yu Leshui went back to bed and fell asleep. Tomorrow, many heads of state of the world will come to congratulate her on her birthday, and she tried her best to dissuade her, but to no avail, everyone said that this is the centennial birthday, and she must come in person no matter what. With so many people to socialize, I have to squint for a while tonight. But she couldn't sleep at this moment, and the contents of the letter played back and forth in her head.

Croswell was right that the contents of the letter should have been a major theoretical breakthrough. The gist is this:

In the relativistic system, when an object moves at high speed in ordinary three-dimensional space, the rate of time slows down. There is a simple relationship between the two, the Lorentz formula (which has the simplicity and beauty that Pauli Ai said). This relationship is classical, definite, and in accordance with the law of cause and effect. It can be called "the causal relationship of first-order space-time";

In the three-state vacuum theory, when an object flies with the help of a second-order vacuum bubble, it does not move relative to the local space, so its time rate is not affected by the relativistic effect and is still stationary time.

But now "Noah" has discovered that the conclusion about wormhole flight is only applicable to local space, and cannot be rashly generalized to non-local space. In other words, the time rate of the spacecraft is unchanged relative to the trumpet-shaped space inside the wormhole, but it may change relative to the large universe outside. How to change? Unfortunately, the relationship between speed and time is no longer classical, definite, and causal. It can only be described by the probability in quantum effects, which can be called "the probability relationship of second-order space-time". The error caused by Noah's observation of the cosmic expansion and contraction cycle was caused by this effect. As for whether there is a third-order and fourth-order space-time relationship, it is not yet possible to assert.

Specifically, when the wormhole spacecraft has experienced a long-term high-Mach flight, the spacecraft's time rate may be faster or slower than that of the larger universe. So, when these spaceships return to the big universe, they may go back to the present, or back to the past, or go to the future. However, according to theoretical calculations, three specific time points have the maximum probability, namely:

Now (relative to the "now" at the moment of departure, it is the median of that time period);

The beginning of the universe;

The end of the universe.

At the end of the letter there is a congratulatory message:

"Humans, bless us!"

After reading the congratulatory message, Yu Leshui was 100% sure that this letter was written by an angel - in his mind, earthlings and astronauts were already two separate species.

This theory is very intuitive, and Yu Leshui can easily understand it with its hundred-year-old declining intelligence, and with its declining intelligence in a low dense vacuum. She was speculating: After discovering this theory, will the "Noah" continue to fly? If you continue to fly, you will have a greater chance of deviating from the present and falling to the beginning of the universe and the end of the universe. Also, can other fleets make this discovery on their own? Is there a way for the Earth to notify them? It is difficult to inform that for those Mach 100 million spacecraft, even the method of "picking up the train" will not work. However, if these uninformed people keep flying in ignorance, then, due to their ultra-high speed (essentially due to the ultra-high second-order vacuum excitation intensity), their space-time coordinates are more likely to deviate from the median and fall to the beginning or end of time.

Croswell says that he wants to hear her wise opinion tomorrow, but unfortunately she doesn't, but Tianle probably does, he is a tide maker on the sea of reason, and likes to take on such challenges. Perhaps Croswell will come tomorrow with Tianle's reply in his pocket, a succinct and clear one.

I hope so. She lay down on the bed with this wish in mind.

It's hard to live. It is difficult for unintelligent creatures, it is difficult for ancestors with ignorant wisdom, and it is equally difficult for new humans who have almost entered the kingdom of scientific freedom. It's just that the content and degree of difficulty are different.

But no matter how hard it is, you have to live. To live is not to escape death, but to enjoy the pleasure (and pain) of living. When life is in a desperate situation, you can't despair, walk up first and then find the way. Yu Leshui gradually entered a state of chaos in these casual thoughts. She saw the hideous-looking Grim Reaper crouching on the top of the hill ahead, the peak at its feet made of countless dead bodies; But the Grim Reaper's expression was depressed, jealous, and miserable. It muttered that I killed all life, but in the end I lost.

In her hazy thoughts, the sky gradually brightened.

[Note 1] Cao Jingzong of the Liang Dynasty made many military exploits and was the general of the Right Guard. Once, Emperor Liang feasted and drank couplets in the Huaguang Palace, and did not let Jingzong participate, Jingzong was uneven, and Emperor Liang persuaded: "Qing has a lot of talents, and talents are heroic, why stop at a poem?" To put it bluntly: you are a military general, why should you be ashamed of writing poems? But Jingzong was drunk and forced to beg for it. So he gave him the rhyme of "competition and illness", but he didn't expect Jingzong to write it.
