After Asahina finished speaking, Ah Xu was already dumbfounded.

However, he was not shocked by Asahina's future identity, he was just unable to fully understand the theories about time mentioned by Minoru for a while.

- In fact, I had already known from the mouth of Nagato Yuki that Nagato was a cosmic person, Chu Xuan was a person from another world, and Senior Sister Asahina was a future person, and Ah Xu, just took a slight look at it, and immediately accepted Shi Jiuru's words.

However, before Ah Xuan could speak, Chu Xuan, who had reflective glasses, preemptively questioned what Shi Jiuru had just said.

"Wait, what I said to you, 'Because time has no continuous surname, even if I change history in this era, it will not affect the future.'" There is a different view on this point.

With the development of quantum physics, we have indeed come to realize that time is not a whole, but that there is what you call 'breaking space close to zero'.

But don't forget that the special surname of light quantum is the 'wave-particle binary surname'.

On the basis of Einstein, de Brogyi extended the 'wave-particle duality' to all microscopic particles, entering and exiting the 'de Broglie wave', that is, the 'material wave'.

It is true that the motion of a single quantum is irregular, and it makes no sense to talk about its trajectory, but there is a certain regularity in the motion of a particular kind of quantum - this is the 'probability wave'.

Time is only a conceptual quantity of the material world and not a real substance, and its basis is matter, that is, all microscopic particles, so the special surname of microscopic particles is also the special surname of time.

The so-called "broken space" in time is nothing more than the interval between the movements of all the quanta in material space, which is the 'particle genus' of time.

But at the same time, time has the surname of 'probability wave', and from the perspective of the material world as a whole, it has the surname of continuity and law.

So it is not accurate to say that changing history has no effect on the future, you can only say that changing history has no effect on the future of the 'original', but the moment you change history, the world jumps to the route where another future lies. ”

"Huh? But that's what our theory is......"

Asahina Minoru pleaded in a timid expression.

As for Ah Xu, he couldn't understand the words of the two of them for a long time, so he could only look blankly at the sparkling waves on the river, allowing Chu Xuan and Shi Jiuru to have academic exchanges with him sitting in the middle.

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

"Is that really your theory? Or maybe only the theories you know are. ”

Chu Xuan asked expressionlessly, and then continued:

"If, according to your theory, time and space are like cartoons, and a few more strokes in one of the pictures have no effect on the subsequent paintings, then you ignore the 'wave-particle duality' of time and completely sever the connection between time and space.

In fact, time itself is a conceptual quantity that cannot be read, it is dependent on the existence of matter, and matter, that is, space itself, has a continuous surname, so that time must also have a continuous surname.

In the same way, the movement of matter is irreversible, and for the universe of a 'plane', the 'entropy' is always increasing until the universe of that plane falls into dead silence.

Even time travel does not jump directly from the end of a line to a point in the middle, but goes around the end in a circle, then coincides with a point in the middle, and continues from that point.

In this process, the motion of matter is not reversed - it does not retreat directly to the same place, but goes in circles and goes back to the point it has walked in the past, and in the process the entropy of the universe has been increasing, not decreasing to the amount it had first walked through.

If, after reaching this point, the time traveler chooses not to contact anyone or make any changes to the environment, and let history go the same way, then it is equivalent to re-drawing the same line that he has traveled before.

Although it may seem as if nothing has changed, as if you have really returned to the 'past', in fact, this 'past' is already a new 'future' experienced by the time traveler.

This is because even if the redrawn line coincides with the original line, it is not the original line after all.

The very act of the time traveler 'going back' to the past has an effect on the past, so that the new line has a slight displacement at the beginning of the 'redrawing', and cannot really coincide with the line of the past - because for the 'real past', there should not have been a time traveler in that space in that time period.

A time traveler who actively changes history after reaching a point again from the end of the line is choosing not to redraw the line from the past, but to draw a new one.

Although the two lines may seem to overlap completely at first, there is an angle between the direction of the next line and the past line, even if the angle is small, the two lines are not parallel, and there will be a time when you can tell them with the naked eye.

This is the new future that is different from the past future. ”

Speaking of this, Chu Xuan poked his head, his glasses glanced at Shi Jiuru, who seemed to be uneasy, and continued:

And, even from the point of view of human behavior alone, your rhetoric is very problematic and illogical.

If changing history really has no effect on the future, then everything you have done in the past is useless, so why send people back in time?

If the observation of the past is only to refine the theory of time and space, to find out the cause of the time fault three years ago and the reason why Haru Suzumiya was able to block the past, then the observer's personal participation in the SOS group has already committed a taboo in scientific observation activities.

Or is it ...... In the 'future', your participation in the development of history as a member of the SOS group is already part of 'history'?

Then your statement that changing history has nothing to do with the future is even more contradictory.

Because if you, the future, don't come back and participate in history, then the 'future' you are in will not exist at all.

- As I said before, from the perspective of the material world as a whole, time is continuous and regular, otherwise there would be no cause and effect.

So, your theory of time can't be what you say it is, and your real mission isn't just to spy on Haru Suzumiya.

If the purpose of the future is not to change the past so that the future can change, then it can only be to prevent anyone from changing the past and thus ensure that the future does not change.

There is also the possibility that your theory of time itself is wrong, and that is in fact that the physical laws of the Plane are not, and that you are now in a loop:

The future invents a way to go back to the past—the future people go back to the past—the future people participate in the history of the past to create the future—because the future people have worked hard in the past, so that the future has finally come—the future has indeed invented a way to go back to the past—the future people can return to the past and let the past develop according to the 'historical process'......

The time gap of three years ago is the farthest point of this loop, and the future you are in must have a farthest point in the future, and you will not only be unable to go to the 'past' that is higher than the one you were three years ago, but also the future that is further than the future you are in.

If you don't seek change, but just let the past develop strictly according to 'history', then you' 'future' people will not only lose the past, but also lose the future, and will just be a bunch of dead souls who keep spinning in place.

So - are you someone with ulterior motives, or a vain necromancy? ”

ps: This chapter may be more difficult to understand than the previous chapter, it is purely used by us to fool people, just like those scriptures in reality that teach people how to cultivate the Tao and refine the pill.

We are only writing books and not engaging in scientific research, and our hypothesis may not be correct, so please don't talk to me about it if you read it carefully and think about any other different theories, or find that the time theory we created is actually logically wrong.

Such purely theoretical chapters will not be found again in this world.
