Chapter 203 Poincaré Returns

After the interrogation of Tang Yun ended, the four finally gathered at the headquarters of the Planetary Security Agency again.

But it's not time to actually close the case yet. There is still one last formality that needs to be done.

Go to the Planet Security Research Laboratory and tell the researchers everything that happened from beginning to end, so that the researchers can archive the case and use it for subsequent research.

Just like last time, this time, the four people were still separated, each was questioned, and each told the entire story of the case from their own perspective.

This time, it was still Professor Ning who received Lu Ming.

"Hello, Lu Ming, congratulations to your second team for solving another problem."

After not seeing him for a while, Professor Ning is still in good spirits. Although his hair is a little gray, it is still neatly combed.

Seeing Professor Ning, Lu Ming felt slightly ashamed.

"This case is probably not solved by us. In fact, we can do very little in this case."

This is indeed the case. Whether the Death Star will hit the earth depends entirely on luck. The entire human world is powerless to interfere in this matter, let alone the second operation team.

"You can't say that."

Professor Ning shook his head: "Through your own analysis, you made the decision to recommend smaller-scale mobilization. As far as I know, your suggestion held a great weight in the final decision. You have avoided the consequences for our human world.

A lot of losses.”

"To be honest, I wasn't sure at the time."

Professor Ning smiled and did not dwell on this topic any more.

"Shall we get started?"

"good."

Lu Ming sorted out his thoughts, obtained the files from the very beginning, and launched an investigation into the crash of flight EU7655, to the subsequent soybean mutant blight, the leakage of chemical substances caused by the earthquake, etc., one by one, one by one, and here.

One’s own response and one’s own thoughts during the process

The examination, judgment, choice, and reasons, etc., were all told exactly as they were. Until now, based on the error of the Death Star's orbit, its possible impact point was deduced, and from this, the location of the Ark base was deduced and occupied.

As well as the final stage of the arrest and interrogation of Tang Yun.

It took Lu Ming two days to fully describe what happened. At this moment, beside Professor Ning, the researcher responsible for recording had already recorded hundreds of pages of documents.

"I'm done."

"good."

Professor Ning carefully read through the documents, while Lu Ming remained silent. Gradually, a thoughtful look appeared on Professor Ning's face.

"So, you don't have the answers to these two most critical mysteries: first, how does time travel happen, and second, since it is time travel, why are there errors?"

Lu Ming nodded: "Yes. And, I think there is a high probability that we will never be able to find the answer. But... I have some guesses."

"Guess? Tell me."

Lu Ming was silent for a moment and said: "I have always believed that time travel in the conventional sense cannot exist."

Professor Ning thought for a moment and said: "Indeed, your speculation makes sense. I also believe that there is only one timeline. Since it is the future, it has not happened yet, so it does not exist at all. Since there is no future timeline

, how to talk about traveling back from the future?"

Lu Ming always believes that there is neither past nor future, only the present exists.

You cannot travel back to the past from the present, and you cannot travel back to the present from the future.

"However, your interrogation also showed that 'time travel' did indeed occur in Tang Yun, or at least something similar to 'time travel' occurred."

"I have two conjectures. The first conjecture is that the so-called time travel is just an illusion.

There is some kind of existence that we don't know - it may be a god, it may be an alien. In short, it is an existence that has mastered some kind of power beyond our imagination. They were there decades ago, on the night when Tang Yun was sixteen.

, a future simulation was conducted based on Tang Yun at that time.

Because they have extremely strong technical strength, they can complete information collection with extremely high precision that we cannot imagine. Based on these data, they conducted a simulation of Tang Yun's future life.

In this simulation, they foresaw almost all of Tang Yun's life, including the future catastrophe caused by the Death Star hitting the earth, and Tang Yun's final death. After the simulation was completed, they would transfer this 'memory'

It was transplanted into Tang Yun's head. This created an effect similar to 'time travel'.

However, since it is a simulation, it is obvious that it will follow this rule: the closer the simulation is to time, the higher the accuracy. The further the time is, the lower the accuracy. From this, the existence of ‘error’ can be explained.”

There is no time travel. It is just a simulation. And since it is a simulation, there must be errors.

Therefore, there is a difference of two minutes between the predicted earthquake time and the actual earthquake time. Therefore, the predicted orbit of the Death Star deviates from the real orbit of the Death Star by more than a thousand kilometers, which leads to two very different endings.

Professor Ning nodded: "This is indeed a conjecture that can explain those two core issues. However, I remember that you denied this conjecture early on."

Lu Ming said: "Indeed. I don't think it is possible to make such precise predictions over such a long time span without touching the randomness at the bottom of the universe."

"The randomness at the bottom of the universe will make this kind of prediction completely unfeasible."

Lu Ming said: "Maybe there is some kind of physical law that we don't know that makes this kind of prediction feasible?"

At the current stage, the human world still knows too little about the universe. Although the physical knowledge that has been acquired so far has a high probability of not being wrong, but just not perfect, it cannot be said that this possibility does not exist at all.

Professor Ning said: "Lu Ming, you seem to be trying your best to convince yourself of this conjecture?"

Lu Ming frowned slightly, then relaxed after a moment: "Yes. Professor Ning. I am actually very conflicted in my heart. I know this conjecture is not reliable, but... I prefer this conjecture to the other conjecture.

That’s the real thing.”

Professor Ning was very interested: "Do you have another conjecture? That conjecture is terrible?"

Lu Ming shook his head: "It can't be said to be scary."

"What is it?"

Lu Ming sighed: "Poincaré is back."

"oh?"

Professor Ning's expression became serious unconsciously.

For a certain type of system, as long as a sufficiently long but finite time passes, it will definitely reach a state that is arbitrarily close to the initial state, or it will definitely return to the initial state itself.

This is the Poincaré regression theorem. A simpler and more popular description of it is that in a closed system, any particle must return to a position infinitely close to its initial position after a long period of time.

For the entire universe, at this moment, the distribution state of all particles in the universe, after a long enough time, at some point in the future, all particles in the universe will inevitably return to the position they are at at this moment.

(Infinitely close).

All phenomena in the universe are fundamentally just different distributions of particles.

Volcanoes, earthquakes, avalanches, the sun burning, black holes swallowing stars, asteroids hitting the earth, supernova explosions...

Everything is just a different distribution of basic particles. The distribution state of these many microscopic particles determines what the universe will look like.

Poincaré's regression theorem shows that at some point in the future, the universe will inevitably appear in a state that is almost completely similar to the current moment.

Of course, this time is very long, so long that it is completely meaningless to ordinary people. But no matter how long it is, it is still limited. Since it is limited, it will definitely happen.

At this moment, a bird caught a bug. At this moment, the girl abandoned the boy, and the boy was crying sadly. At this moment, someone won the lottery and was extremely happy. At this moment, deep in the universe, two neutron stars collided

Together, strong gravitational waves were released. At this moment, the black hole roared and swallowed a star...

At this moment, countless things are happening simultaneously in the universe.

But long enough in the future, after a Poincaré return time, it will all happen again.

What has happened before will happen again.

Professor Ning considered the language: "Lu Ming, are you saying that Tang Yun's memory about the future actually comes from the past - from a past before Poincaré returned to time? In that world,

Has everything we’ve been through happened?”

Lu Ming nodded.

"It's really a crazy guess."

Professor Ning sighed: "Then, how do you explain the existence of errors?"

Lu Ming took the paper and pen and drew two intersecting straight lines on the paper.

"There is a principle that different causes may lead to the same effect, and the same cause may lead to different effects. Cause and effect do not correspond."

Just like pressing a switch, the light may not always come on.

Professor Ning nodded: "Judging from the randomness at the bottom of the universe, this is indeed the case."

Lu Ming pointed to the piece of paper in front of him: "These two lines represent the process of our world and the process of the world before Poincaré's return time."

Professor Ning lowered his head and looked over.

Lu Ming continued: "Poincaré's return occurs at the intersection. At this moment, the two worlds are extremely similar. But it is only this moment."

"The 'causes' of the two worlds are different, but they lead to the same result, that is, the intersection. At the same time, later on, the same 'cause' of the intersection leads to subsequent different 'effects'. So.

, the two straight lines intersected only once, and since then they have moved away from each other, with no possibility of intersection again."
