Paranormal incident investigation notes

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 really close the case yet. There is 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 was a little gray, it was neatly combed.

Seeing Professor Ning, Lu Ming felt slightly ashamed.

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

And indeed it is. 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.

"let us start?"

"good."

Lu Ming sorted out his thoughts, obtained the files from the beginning, and launched an investigation into the crash of flight EU7655, to the subsequent soybean mutated blight disease, the leakage of chemical substances caused by earthquakes, etc., one by one, and here. During the process, our response, our thinking, judgments, choices, and reasons were all told exactly as they were. Until now, based on the error in the orbit of the Death Star, we have deduced its possible impact point, and from this The location, occupation, and final stages of Tang Yun's arrest and interrogation were revealed.

It took Lu Ming two days to tell the complete story. At this moment, the researcher in charge of recording beside Professor Ning has recorded hundreds of pages of documents.

"I'm done."

"good."

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

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

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 is impossible."

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 has always believed that there is neither past nor future, only the present.

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 unknown to us - 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 capabilities, 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 history, including the future catastrophe caused by the Death Star hitting the earth, and Tang Yun's final death. After the simulation was completed, they transplanted this 'memory' into Tang Yun's head. This creates 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 back in time, the lower the accuracy. From this, the existence of ‘error’ can be explained. "

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

Therefore, the predicted earthquake time differed by two minutes from the actual earthquake time. Therefore, the predicted orbit of the Death Star deviated from the real Death Star orbit by more than a thousand kilometers, resulting in 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 this 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 guess? Is that scary guess?"

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 elementary particles. The distribution state of these many microscopic particles determines what the universe will look like.

The Poincaré Regression Theorem states that at some point in the future, the universe will inevitably appear in a state almost exactly similar to the present 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 limited. Since it is limited, it will definitely appear.

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

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

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

What has happened before will happen again.

Professor Ning considered the words: "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, Everything we’ve been through has 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 flipping a switch, the light doesn't 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 different subsequent '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.”

Lu Ming nodded: "This is the source of the error."

Professor Ning said: "I understand. But do you have any evidence to support this conjecture?"

"There are some things that I don't know if they can be considered evidence."

Lu Ming said: "We interrogated Tang Yun. We found that some historical details of Tang Yun's 'previous life' were different from his current life. For example, the names of several famous historical figures differed by one word, and some historical events , the time is also off by several hours to several days.

After statistics, we found that the more distant the historical events, the greater the deviation. The closer the distance, the smaller the deviation. Until the moment of 'intersection', the two worlds basically coincide. But after the intersection, there are deviations in the course of the world, those errors that we observe. "

All of this is just like the two straight lines drawn by Lu Ming. They were originally far apart, but slowly got closer and eventually intersected. After intersecting, they moved further and further apart.

"This should be considered a support."

Professor Ning gave the conclusion.

Lu Ming nodded.

"Okay. Assuming that Poincaré has returned, how did the memory of Tang Yun in the previous life come to Tang Yun's head in this life?"

"I have no idea."

Lu Ming shook his head: "In fact, our theoretical system does not cover this possibility at all."

Professor Ning thought silently for a moment, and finally discovered that this kind of thing could not happen under the current theoretical system.

When Poincaré returned, all matter was reorganized and all information was lost. How could such a transmission happen?

"Perhaps...a high-dimensional world? The high-dimensional world obtained information from the observations at that time, and then returned the information today?"

"Not feasible."

Lu Ming shook his head and denied this conjecture: "If the high-dimensional world can observe our universe, then it either means that the high-dimensional world is part of our universe, and the Poincaré regression also involves the high-dimensional world, or it means that our universe The universe is not closed, so Poincaré’s return is out of the question.”

Poincaré regression only applies to isolated closed systems.

Professor Ning frowned and thought hard for a long time, and finally smiled bitterly and shook his head.

"Well, it seems that both of our conjectures have fatal flaws. The first conjecture will encounter random obstacles at the bottom of the universe. The second conjecture will encounter obstacles from particle reorganization and information loss."

"yes."

Lu Ming sighed: "So, I still can't figure out how those prophecies about the future come from."

"Okay, don't think about it anymore."

Professor Ning said: "You have done a good enough job. There are too many unknowns in this universe. With our current ability, there is really no way to figure everything out clearly. Maybe we are thinking about everything now. I don’t understand, but the truth is actually very simple? Maybe there are some deviations in our understanding of the universe. For some unknown beings, the universe may be very simple?

Maybe... this is just a prank by some boring alien passing by the earth? "

Lu Ming also laughed: "Indeed. It's better not to think about things you don't understand for the time being."

"So, do you have anything else to add?"

"there is none left."

"Okay. Let's do this for now."

Professor Ning stood up and shook hands with Lu Ming: "I hope to see you next time to tell me how you dealt with another trouble."

"There will be. Then, goodbye."

"goodbye."

Lu Ming left the Planet Security Research Laboratory and came to the office area of ​​Operation Team Two. Zhang Dingshan, He Wei, and Lu Qingliang were already waiting there.

"So, has everyone decided on a vacation?"
