The best director ever

Chapter 472 How Did I Travel Over Time?
high-dimensional space exists
Han Qiu couldn't help being a little shocked. Although he had seen Interstellar Crossing in his previous life, it was just a movie after all, and he still couldn't understand what kind of existence a high-dimensional space is.

"Principal, what does a high-dimensional space look like?" Han Qiu asked in confusion.

"Didn't you create a five-dimensional space in the outer space zone?" the principal asked back.

"That's just my imagination, and I don't know what the real five-dimensional space looks like."

"Hehe, I told you this, but you don't understand." The principal said: "In fact, theoretically speaking, the high-dimensional space is hidden in the universe, but we can't see it."

"Uh..." Han Qiu was stunned.

"How many dimensions do you think the world we live in is?" Xiao Zhang asked.

"Three-dimensional."

The principal nodded, then shook his head again: "That's incomplete. We live in a three-dimensional space, but we also live in a four-dimensional space-time."

"Four-dimensional?" Han Qiu was even more confused, "Isn't this three-dimensional, how did it become four-dimensional?"

"Pay attention to my words, space and time and space! For example, this room is a three-dimensional space. To be precise, it is a four-dimensional time and space!"

"Eh, what is one-dimensional?"

"Time!" The principal laughed: "Time is also a dimension, but it's just a pseudo-dimension. Its unit is different from the space unit. So it can be attached to any space. We live in three-dimensional space, plus time , it becomes a four-dimensional space-time.”

"Oh~~~" Han Qiu understood a little bit, "Does it mean that if animation is a two-dimensional space, and time is added, it becomes a three-dimensional space-time?"

"That's almost what it means." The principal nodded: "Time is an essential dimension of space. Without time, space is static. Just like the animation you said, without time, it is equivalent to a suspended state."

The principal continued: "Anime characters on paper are two-dimensional creatures living in three-dimensional time and space, while we humans are three-dimensional creatures living in four-dimensional time and space."

[-]D creature
Hearing this, Han Qiu always felt a little weird.Are you a three-dimensional creature?
Suddenly, he thought of something, his face changed, and he said in shock: "Then there are higher-dimensional creatures, such as four-dimensional creatures living in five-dimensional time and space?"

The headmaster looked at Han Qiu unexpectedly, but he didn't expect this kid to think of this.

"This is theoretically possible, but there is no actual evidence." The principal said, "No one knows what kind of form a four-dimensional creature exists, even if it does exist, even if it appears in front of you , you can't see it either."

Han Qiu looked at the principal suspiciously, damn, I'm not blind, how could I not see?

Seeing Han Qiu's expression, the principal knew what he was thinking. "Hehe, don't believe me, I'm serious, even if a four-dimensional creature appears in front of your eyes, you won't be able to see it."

"I do not believe."

The principal was not in a hurry, and slowly explained: "Do you know what our three-dimensional space looks like in the eyes of two-dimensional creatures? It is a plane, and we humans are like a compressed pie in their eyes. They have no way of knowing what we humans are like."

"Similarly, we humans look at four-dimensional creatures in the same way. Even if it appears in front of us, we have no way of knowing what it looks like. Simply put, they cannot be understood by 'seeing'."

The headmaster bit the word "look" very hard.

Han Qiu also understood a little bit, "Okay, but I still don't understand why we humans have to think so hard about these high-dimensional spaces. According to the theory, we are three-dimensional creatures, so what does those high-dimensional spaces have to do with us? "

The principal gave Han Qiu a blank look: "You are a director, of course you don't care about these things. Because we human beings want to use a unified theory or formula to explain all the natural phenomena that appear in the universe. But it is impossible now, just For example, some theoretical formulas are applicable on the earth, but they are not applicable in wormholes. Modern physicists study high-dimensional space in order to explain all this with a unified theory, so that the same formula can be used in all applicable to all circumstances.”

The principal said word by word: "In the eyes of these physicists who study high-dimensional space, they believe that only by standing on the highest dimension of the universe can there be a formula that can solve all natural phenomena. Some formulas cannot be applied to wormholes. , because the level is too low."

The headmaster wanted to continue talking, but Han Qiu's eyes were already dazzled.

Ahhh, I'm going to die, I'm going to die.

"Stop, stop." Han Qiu shouted immediately: "Principal, you don't need to tell me about these things. Let's talk about something related to movies."

The principal was speechless: "Well, I've said so much for nothing."

Han Qiu is also speechless, I have heard so much for nothing.

"Principal, tell me, is it really possible for the protagonist of the movie to change history through five-dimensional time and space?"

"Who knows? This kind of thing can only exist in sci-fi movies at present, at least it has not been proven in reality." The principal did not completely deny Han Qiu, "But there is nothing wrong with the direction of your idea."

"In the five-dimensional space-time, time is quantified into an observable existence. Just like what you said in your lines, going up the mountain is going to the future, and going down the mountain is going back to the past. Perhaps, four-dimensional creatures do have the ability to change history," said the principal. : "Just think about it, it can't be true."

"Oh." Han Qiu nodded.

Then, the principal picked up a piece of paper, marked A and B at both ends, and then drew a line to connect A and B.

"Remember the script you wrote?"

"Of course I remember." Han Qiu replied.In fact, after seeing the principal do this, he knew what the principal was going to do.

Isn't it just a wormhole folding jump?

"There is no problem with what you wrote in the script. If a two-dimensional creature wants to go from A to B, it would have to go through such a long distance." The principal pointed to the line segment AB, and then folded the paper at once, so that AB coincided, and at the same time Use a pen to poke a hole in the overlapping letters. "But folded up and passed through this wormhole, it will undoubtedly be much faster, and it will arrive almost instantly."

"In the eyes of two-dimensional creatures, a wormhole is a flat hole, but in the eyes of our three-dimensional creatures, a wormhole is just a ball." The principal gave Han Qiu an approving look, "The explanation in your script about this is quite different. The audience was not misunderstood."

"Hehe." Han Qiu pulled the corner of his mouth and laughed wordlessly.

"But have you ever thought about it"

"what?"

"I'm talking about hypotheses, hypotheses." The principal swallowed, pointed to the paper and said: "Our three-dimensional creatures can distort and splicing their space for two-dimensional creatures, so that they can go directly from A to B, so can four-dimensional creatures." Distorting and splicing the space of our three-dimensional beings."

Han Qiu nodded: "That's right, that's what I wrote in the script. Future humans go to high-dimensional space and create wormholes in modern times to help modern humans get out of trouble."

"Then have you ever thought about it? High-dimensional creatures created a wormhole in the past world to help past humans escape. In other words, they can not only distort space, but also distort and splice time." The principal said: "This is for It provides a basis for changing history and traveling through time and space."

After finishing speaking, the principal laughed dryly: "Hehe, of course, this is just a hypothesis. Aren't there many TV dramas and novels that travel back to ancient times? Maybe this theory can explain it. These time travelers may all be backed by high-dimensional creatures. Give them a hand."

"Uh, principal, do you also read these things?" Han Qiu looked shocked.

"I haven't seen it, but I've heard a lot about it." The principal shook his head.

"This is just novels and TV dramas. I heard some people say that they can't go back to the past? If they changed history, wouldn't it have an impact on the present? This is a paradox!"

"Time and space! It's a combination of time and space!" The principal said angrily, "Is high-dimensional space not only five-dimensional? The super-glare theory has reached eleven dimensions. In five-dimensional space-time, time can be distorted. Just like your outer space The space zone, in the five-dimensional space, isn’t it just a link of time points.”

"Our three-dimensional creatures can only see scenes at a certain time, while four-dimensional creatures can see scenes at all time points in the past and the future. What about higher dimensions? Not only can they see all time points, but they can also see other point in time."

"That's parallel space!"

The headmaster smiled and said, "Don't you young people like superficial novels and TV dramas? This is it. Four-dimensional creatures can travel back and forth in the past and future of a certain time and space. Higher-dimensional creatures can travel in different time and space. , walking in the past and future of every time and space."

"Perhaps, those people who have traveled to the past, or to other parallel time and space, which is what you young people call other worlds. Maybe those high-dimensional creatures are behind the scenes!"

boom!
Hearing this, Han Qiu was shocked!
Grandma's, Lao Tzu is a time traveler, and he has traveled to a parallel world with a slightly different trajectory in modern times.

Damn, wouldn't it be those high-dimensional creatures who did it?
Thinking of this, Han Qiu suddenly raised his head.
