Someone couldn't help but feel guilty. 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 Bailu 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 better than Wade. In Wo's eyes, he is very weak and might not even be able to defeat the children in the tribe. But he happened to be quite favored by His Majesty the Demon King, and he didn't even 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. One would not be so naive as to think that the strongest warrior in the tribe, Thor, could only fly after a few moves, but this man had the strength to defeat the Demon King.
Since he asked a question today, His Majesty showed interest first, so of course Waldwal had to listen. This man also talked about his observations and discoveries during this period of time. 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 instantly made a certain man's face freeze. Qing said that the experience report he just gave was so frothing at the mouth that it turned out to be useless.
Lin struggled to turn his stiff neck and looked at the lich who had been working with this beast for several days. I want to say something, but I just can't say it. I'm afraid that as soon as I open my mouth, it will be all kinds of nonsense. Take a deep breath and realize that you are well-educated and not worthy of being angry with a tree.
As if sensing that someone was about to go crazy, Fen playfully stuck out the tip of his 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, the eyes of one person and one deer 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, saying: "This is mathematics, it is my experience from the basics to now. Take a look and ask if you don’t understand.”
It seemed that there was collusion, one person and one deer, one person and one person singing together, without giving Lin a chance to interrupt at all. Bai Lu sat down on the ground and opened the screen of Water Mirror Technique. The words flowed upward like a waterfall. After a while, he saw the end of the page. Waldwall shuddered, snorted again, and said:
"It turns out that the world I see looks like this in your eyes. I have never understood why most wood elves or other homo sapiens species cannot 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. But you mentioned that the high-dimensional world that I can see and touch doesn’t seem to be the same. Equal; there are also things like I am growing towards a high-dimensional world, etc. But why do the magicians who study me always find the magic of the teleportation array in me, or some... Well, what's wrong with you?"
Exhausted. Lin moved to a corner of the tent and put his head on the tent pole, not wanting to see anyone. One second, he was still a math novice; the next second, he could already understand the theory that even he had not fully understood.
"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 not come and explain to us whether what you observed is correct? Those magicians are still right."
I turned around helplessly, and the little bit of self-esteem I had left had been completely beaten to pieces. Now seeing 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 took out a piece of paper from his arms, spread it flat on the ground, took out a quill and dipped it in ink, then tapped a dot on each end 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?"
Fen felt like he was being insulted by a question of this magnitude. However, she still said the answer 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 jumped out like a water snake, and finally fell on the paper. It is a straight line without any skew between the two points that Lin drew. "──According to your weights and measures, the distance between these two points is 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 what is right or wrong, I will always follow the footsteps of His Majesty the Demon King. But for the question Lin raised, I believe that the devil's answer is already the most perfect answer, and there will be no better answer. So he nodded firmly.
", you are all wrong."
Lin's words undoubtedly made everyone feel unconvinced. The white deer dug its front hooves at the ground and snorted; Fen put his hands on his hips, waiting for someone to explain. If it was too far-fetched, she would definitely not give up.
I saw someone pick up the paper and fold it in half. After touching the two points together, poke the tip of the quill through the two points on the paper. "The shortest distance is no distance."
"Hey~!" One person and one deer looked at this cheating game. They first exclaimed and were dumbfounded, and then they looked serious and thoughtful. In fact, they 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 become clear and understandable. but why?
Lin continued: "This has a name in physics, the Einstein-Rosen Bridge." Putting down the paper, he used whiteboard penmanship to simulate a star, and changed its presentation along with the explanation. "When a star with enough mass ends its life, it actually 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 In an instant, everything will be burned again and cause expansion. At this time, a supernova explosion will occur. At this time, after the second combustible element is burned out, the phenomenon of inward collapse will not stop, and it will continue to shrink its own volume. In terms of mathematics As an analogy, there is a number of 100, and it 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 secondary explosion A star is constantly shrinking due to gravity. When it shrinks to a size no longer small, it will break through the boundaries of space and begin to continue to twist 'inward'."
It is not a difficult explanation for an older child who has some understanding of geophysics. Because even if you can't get through the difficult physics textbooks, this is still considered a bad subject in various science fiction and dramas. But Lin still gave one person and one deer some time to think, and drank some water by the way. When their attention returned to themselves, 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 punctured paper again. On one side, the pen tip shows through the hole, sinking into the plane of the paper, and the tip is not visible. Turning it over, you can see that the pen tip penetrates the paper through the hole, 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 this phenomenon." Use whiteboard technique to draw quills and thorns in the air Through the three-dimensional image of 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 quills to move in and out, making them extend and retreat on their respective planes. Although the quill pen is divided into two parts when viewed from a flat piece of paper, it is not that the broken pen is in two places, but exists 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 can be shortened in the three-dimensional world 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 penetration into higher dimensions. As you mentioned, does it have anything to do with the fact 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. Those who originally planned to stop there, saw Bai Lu's appearance, and thought that now that they were living under someone else's roof, it was unreasonable to have to hide any achievements. Although those ideas are just speculations, not to mention that I came to them today just to brainstorm and discuss a feasible direction.
