Chapter 280 The shortest distance between two points
Someone involuntarily felt a sense of guilt in his heart. He quickly changed the topic and returned to his original destination and said: "I have gained some insights from my recent research, and I also have some questions. I would like to ask Lord Waldwal."
The named Bai Lu put away the screen of Water Mirror Technique, faced Lin, shook his head, snorted, and then said: "If you have any questions, please ask." For this man, his strength is greater than that of Wade.
In Wo's eyes, he is very weak and might not even be able to defeat the children in the tribe. However, he is quite favored by His Majesty the Demon King, and he does not dare to ignore him.
Not to mention that he was almost killed by His Majesty the Demon King before, but it was only because of this man's intervention that he escaped. You wouldn't be naive to think that the strongest warrior in the tribe, Thor, could fly away after just a few moves, but this man had
The strength to surely defeat the Demon King.
Since he asked a question today, His Majesty showed interest first, so of course Waldwal had to listen. The man just talked about his observations and discoveries during this period. Finally, he asked
: "Lord Waldwal, what is your opinion?"
But after listening to this man's words very carefully from beginning to end, Wadwo said: "Well, I only have one question, what are dimensions?"
A very powerful rhetorical question, which instantly made a certain man's face freeze up. The emotional report he just made was so frothy at the mouth that it turned out to be useless.
Lin Fenfeng turned his stiff neck and looked at the lich who had been working with this beast for several days. He wanted to say something, but he couldn't say it. He was afraid that as soon as he opened his mouth, he would end up having all kinds of sex. He took a deep breath and said to himself
You are very well-educated and not worth getting angry with a tree.
As if sensing that someone was about to go crazy, Fen playfully stuck out the tip of her tongue and said, "I forgot to teach you first."
"Some people don't learn the most basic mathematics, but instead learn programming. What's more, the algorithms you use for prediction now are completely based on mathematics... Are you doing what I'm talking about?"
Following someone's last sudden question, one person and one deer's eyes drifted outward, which only made Lin Da feel bad. He immediately wanted to ask what the hell they were doing, but Fen took the lead and pretended to open the water mirror screen.
, picked a file and threw it to Wadwo, and said: "This is mathematics. It is my experience from the basics to the present. Take a look and ask if you don't understand."
It seemed that they had colluded, and one person and one deer sang together, without giving Lin a chance to interrupt. Bai Lu sat down on the ground, opened the screen of Water Mirror Technique, and the words flowed upward like a waterfall in reverse flow. After a while, it was
When he saw the end of the page, Waldwall shivered, snorted again, and said:
"It turns out that the world I see looks like this in your eyes. I never understood why most wood elves or other species of Homo sapiens can't touch what I see.
Things. I originally thought it was because they were too weak, but in fact some strong people who even I found troublesome were in the same situation. They couldn't see what I saw. On the contrary, some magicians could spy on a small part of it.
, and these magicians are not necessarily staggeringly powerful. It’s just that there are some worlds that I can only see but cannot touch. However, you mentioned that the high-dimensional world that I can see and touch does not seem to be the same.
Equal; there are also things like I am growing towards a high-dimensional world, etc. But why do those magicians who study me always find the magic of the teleportation array in me, or some... Well, what's wrong with you?"
My heart was so tired. Lin moved to a corner of the tent and held his head against the pillars that set up the tent. He didn't want to see anyone. One second, he was still a math novice; the next second, he could already understand that even he hadn't fully figured it out yet.
clear theory.
"Okay, don't be depressed." Fen came to the man's side with a bit of teasing and said: "If you have time to feel down over there, why don't you come and explain to us whether what you observed is correct?
Those magicians are still right."
Looking back with extreme helplessness, what little self-esteem he had left had been completely beaten. Now looking at the two people looking at each other with hopeful eyes, Lin thought for a while and decided to use the most commonly used example to explain. He
He took out a piece of paper from his arms, laid it flat on the ground, took out a quill and dipped it in ink, then tapped a dot on both ends of the paper and asked:
"We know that there are two points on this piece of paper. What do you think is the shortest distance between these two points?"
For a question of this magnitude, Fen felt like she was being insulted. However, she still answered seriously: "Of course the shortest distance is the straight line distance between two points.──" At the same time, she hooked her finger, and the ink on the tip of the pen was like water.
It jumped out like a snake and finally landed on the paper. It was a straight, unskewed line between the two points drawn by Lin. "──Explain according to your weights and measures, the distance between the two points
It’s 16.717 centimeters.”
Seeing what Fen said was categorical, Lin looked at Bai Lu and asked, "Is this also your opinion?"
Let’s not talk about whether it is because of fear, so no matter what it is, no matter whether it is right or wrong, we always follow the footsteps of His Majesty the Demon King. But to the question Lin raised, I believe that the Demon King’s answer is the most perfect answer.
, there won’t be anything better. So he nodded firmly.
",You are all wrong."
Lin's words undoubtedly made everyone feel unconvinced. The white deer dug the ground with its front hooves and snorted; Fen put her hands on her hips, waiting for someone's explanation. If it was too far-fetched, she would definitely not give up.
I saw someone picking up the paper and folding both ends in half. After touching the two points together, he pierced the two points on the paper with the tip of the quill. "The shortest distance is no distance."
"Eh~!" One person and one deer looked at this cheating game. First they exclaimed, dumbfounded, and then they looked serious in thought. In fact, they had already understood many things, but they just didn't connect them together. At this time
As long as someone breaks the window paper, many things will be clear and obvious. But why?
Lin continued: "This has a name in physics, the Einstein-Rosen bridge." He put down the paper and used whiteboard writing skills to simulate a star, and changed his demonstration along with the explanation. "When the mass is large enough,
The end of a star's life is actually when it burns itself out and begins to collapse inward because it cannot resist its own gravity. At this time, the heavy elements inside will continue to increase due to pressure. After crossing the limit point, they will all burn again in an instant and
Causes expansion, and a supernova explosion will occur. At this time, after the second combustible element is burned out, the phenomenon of inward collapse will not stop, it will continue to reduce its size. Using mathematics as an analogy, there is a number
is 100, and will continue to decrease by 1 as time goes by. But 0 is not the end point. When it crosses 0, it will become a negative number and continue to decrease by 1. This star that has undergone the second explosion continues to expand due to gravity.
The phenomenon of shrinkage, when it shrinks to a size that cannot be smaller, it will break through the boundaries of space and begin to continue to twist 'inward'."
It's not a difficult explanation for older children who have some understanding of geophysics. Because even if they can't handle difficult physics textbooks, this is considered a bad subject in various science fiction novels and dramas. But Lin still left it to
Each of them had some time to think, and drank some water by the way. When their attention returned to themselves again, they continued:
"I call this thing that is constantly twisting inwards and swallowing matter a 'black hole'. So where do the swallowed things go?"
Lin showed the pierced paper again. On one side, the pen tip passed through the hole and was submerged into the plane of the paper, and the pen tip could not be seen. Turning over, you can see that the pen tip penetrated through the hole and penetrated the paper.
, but the pen body cannot be seen.
"What goes in must come out. At the other end of this twist, is there a 'white hole' that spits things out? In the end, it formed a phenomenon like this." Use the whiteboard technique to draw quills and thorns in the air.
To create a three-dimensional image through the paper, Lin then folded the paper from half to flat, but kept the pen body and nib on their respective planes.
And control the quill pen to move in and out, allowing it to extend and retreat on its own plane. Although the quill pen is divided into two parts from a flat paper, it is not a broken pen divided into two parts.
two places, but exist in two places at the same time while still being connected to each other.
Lin then showed some classic animations simulating high dimensions, and concluded: "When the dimensions of things increase, some things that seem impossible in our eyes will become natural. In a two-dimensional plane
The shortest distance in the three-dimensional world can be shortened through distortion, or even the distance is zero. Similarly, when we can access the higher-dimensional world, some things that seem impossible in the three-dimensional space can
In fact, it is not that difficult. Therefore, it can be said that teleportation is only one of the most superficial mysteries of World Tree."
"In other words, the bigger secrets on the World Tree are actually related to contact and going deep into higher dimensions. Does this have something to do with what you mentioned, that the world Waldwo saw is not the same as the world he touched?"
Regarding Fen's question, Lin used that simple metaphor to explain: "I'm not sure what the 'world' that can be observed by the World Tree looks like. But I'm guessing, does it feel like I can see the sky?"
, but it does not mean that you are in the sky. If you want to go to the sky, in addition to having a goal, you must also have a method. For Lord Waldwo, the goal is the high-dimensional world he sees,
There should be no doubt about this. Then the question is how to reach those worlds."
Hearing that it was related to him, Bai Lu raised his head and straightened his ears, seriously waiting for the follow-up. The person who originally planned to stop there, saw Bai Lu's appearance, thought that now he was living under someone else's roof, and any achievements had to be hidden.
It just doesn't make sense. Although those ideas are just speculations, not to mention that I came to them today just to brainstorm and discuss a feasible direction.
