After Asahi Na Shikuru finished speaking, Ah Xu was stunned.

However, he was not shocked by Asahina Shikuru's identity as a future person. He just couldn't fully understand the theories about time mentioned by Shikuru for a while.

——In fact, I had already learned from Nagato Yuki that Nagato was a cosmic man, Chu Xuan was a native of another world, and Ah Xu, who was a future man, was stunned for a moment and immediately accepted Mikuru's words.

However, before Ah Xu spoke, Chu Xuan, whose glasses were reflective, questioned what Shijiru had just said.

“Wait, I have a different view on what you said, ‘Because time is not continuous, even if I change history in this era, it will not affect the future.’

With the development of quantum physics, we have indeed realized that time is not a whole, but there is what you call "a fracture space that is approaching zero."

But don't forget that the characteristic of light quantum is "wave-particle duality".

Based on Einstein, de Broglie extended the "wave-particle duality" to all microscopic particles, entering and exiting the "de Broglie wave" - ​​that is, "matter wave".

The movement of a single quantum is indeed irregular, and it is meaningless to talk about its motion orbit, but a specific type of quantum motion has certain regularity - this is the 'probability wave'.

Time is just a conceptual quantity of the material world rather than a real matter. Its basis is matter, that is, all microscopic particles, so the characteristics of microscopic particles are also the characteristics of time.

The so-called "breaking space" in time is just the interval between all quantum movements in matter space, which is the "particle property" of time.

But at the same time, time has the properties of a ‘probability wave’, and it is continuous and regular from the perspective of the material world as a whole.

So what you said is inaccurate to change history without any impact on the future. It can only be said that changing history has no impact on the future of ‘original’, but in the moment of changing history, the world jumps to another route where the future is.”

"Hey? But that's how our theory is..."

Asahina Shikuru hesitated and said with a timid look on her face.

As for Ah Xu, he could not understand the two of them, so he could only look at the rippling waves on the river in a daze, allowing Chu Xuan and Shijiru to conduct academic exchanges between him, who was sitting in the middle.

The left ear was poured into a difficult theory, and the right ear was poured into another more difficult theory. Ah Xu felt that his brain had become a cloud of mucus.

"Is your theory really like this? Or maybe only theories you know are like this."

Chu Xuan asked expressionlessly, and then continued:

"If according to your theory, time and space are like cartoons, and drawing more strokes in several pictures has no effect on the subsequent paintings at all, then it ignores the 'wave-particle duality' of time and completely separates the connection between time and space.

In fact, time itself is a conceptual quantity that cannot exist. It is attached to the existence of matter, and matter - that is, space itself is continuous, so time must also have continuousness.

Similarly, the movement of matter is irreversible. For a cosmic space of a ‘plane’, ‘entropy’ always increases until the universe of that plane falls into silence.

Even time travel does not mean jumping directly from the end of a line to a point in the middle, but instead goes backwards at the end, then coincides with a point in the middle, and continues to walk from this point.

In this process, the movement of matter is not reversed - it does not retreat directly to its original position, but goes around a circle and then to the point that has been passed by in the past. In this process, the entropy of the universe has been increasing, rather than decreasing to the amount when it first passed this point.

If the time traveler has reached this point and chooses not to contact anyone or make any changes to the environment, and lets history move on the original route, it is equivalent to re-drawing along the line you walked before.

Although it seems that nothing has changed, it seems that it has really returned to the "past", in fact, this "past" is already a new "future" experienced by time travelers.

Because even if the re-drawn line coincides with the original line, it is not the original line after all.

The act of time traveler ‘returning’ to the past will have an impact on the past, so that the new line has a slight displacement at the beginning of ‘re-drawing’ and cannot truly coincide with the past line – because for the ‘real past’, there shouldn’t be a time traveler in that space during that time period.

If a time traveler reaches a certain point again from the end of the line and actively changes history, it is equivalent to choosing not to re-draw the past line, but to draw a new line.

Although the two lines may seem to be completely overlapping at the beginning, because the direction of moving forward again has an angle with the line in the past, even if the angle is small, the two lines are not parallel. If you keep drawing it, you can finally distinguish it with the naked eye.

This is a new future that is different from the future of the past."

Speaking of this, Chu Xuan looked at Shijiru, who seemed to be anxious, and continued:

“And, even if you analyze it from the perspective of human behavior alone, your statement is problematic and illogical at all.

If changing history really has no impact on the future, then everything you have done in the past is useless, so why should you send someone back to the past?

If observing the past is just to improve the space-time theory, find out the causes of the time fault three years ago and the reasons why Haruhi Suzumiya was able to block the past, then the monitors have committed the taboo of scientific observation activities in person to participate in the SOS team.

Or... In the ‘future’, is this behavior that you have participated in the development of history as a member of the SOS team already a part of ‘history’?

Then, what you said to change history has nothing to do with the future is even more contradictory.

Because if you, a future person, does not come back to participate in history, then the "future" you are in will not appear at all.

——I have said before that from the perspective of the entire material world, time is continuous and regular, otherwise there would be no causal relationship.

So, your time theory is simply impossible to be like you said, and your real task is not just to monitor Haruhi Suzumiya.

Future people return to the ‘past’ and must participate in history personally. If their purpose is not to change the past so that the future will change, then it can only prevent anyone from changing the past, so as to ensure that the future will not change.

In addition, there is another possibility, that is, your time theory itself is wrong, but in fact, the physical laws of the original plane are not like this, and you have actually entered a vicious cycle now:

The future invented the method of returning to the past - the future people return to the past - the future people participate in the past history to create the future - because the future people's efforts in the past finally arrived - the future indeed invented the method of returning to the past - the future is thus able to return to the past and let the past develop according to the "historical process"...

The time fault three years ago is the furthest point of this vicious cycle, and the future you are in a farthest point must have a farthest point. Not only can you not go to the "past" that is ahead of you than three years ago, but you can also not usher in a "future" that is further away than your future.

If you do not seek change and just let the past develop strictly according to "history", then you "future people" will not only lose the past, but also lose the future, just a group of undead who keeps spinning in place.

So—are you a person with ulterior motives or a futile necromancer?”

PS: This chapter may be more difficult to understand than the previous chapter. It is purely used to fool people, just like the scriptures in reality that teach people how to practice Taoism and alchemy.

We are just writing books instead of scientific research, and our hypothesis may not be correct, so if you read them carefully and think about other different theories, or find that the time theory we created is actually logically wrong, please don’t ask me to discuss it.

Such pure theoretical chapters will not appear again in this world.
Chapter completed!
