Blackness space

Feng Ming was still walking the stairs, and he didn't know how long he had been walking. "What the hell is wrong?" Feng Ming wondered, this base was not very high, but he always felt that he was climbing the stairs all the time, and he had never walked down. Such a strange phenomenon made Feng Ming have to stop and think about it. He remembered that before he came in, Hahime had said that he would never escape from this space, was that the reason? because he couldn't get out of this staircase??

The more Feng Ming thought about it, the more he felt that something was wrong, he had been on the top of the stairs since he first came in, and he hadn't walked out until now, he might have ignored something. Feng Ming ignited a cluster of purple flames in his hand and launched them towards the void, and in the blink of an eye, the purple flames disappeared into the space, seemingly unable to escape.

"Stairs, stairs?" Feng Ming muttered these two words repeatedly, as if intending to find some clues from these two words. Suddenly, Feng Ming had a flash of inspiration, and a dialogue scene appeared in his mind: "Great Scientist Feng, what are you always sitting in front of the computer trying to figure out?" The person who spoke was Song Zhe, and the one who spoke to him was Feng Ming himself.

"Come on, don't be scared, say you're fat and you're gasping for me, what are you doing, don't answer me when you send you a message. ”

Song Zhe complained in a complaining tone.

"Stone, come and see. Feng Ming didn't explain exactly what he was doing to Song Zhe, but called him to the computer.

"Triangles??What are you doing here, you don't know about math, I can't be your teacher. "Can you open your little sesame eye a little wider, which of your eyes can see that it's a flat triangle? Feng Ming really couldn't listen to it anymore, so he said. "Do I have small eyes? I feel like my eyes are pretty good!" he said and winked at Feng Ming.

"It's shameful to be cute, I'm not breaking my sleeves! Don't make a fuss, I'm talking to you about business. ”

"What you're saying is that you want me to help you see this triangle, no, it's a three-dimensional tripod composed of three cuboids, is this in your way?"

"Do you know the Penros Triangle?" Feng Ming asked. Song Zhe shook his head, "What's wrong?" "The Penrose Triangle is a well-known refutation in the scientific community, and it is accompanied by the Penrose Staircase and the Penrose Space. "What's the problem?

"To put it in layman's terms, once you walk into the Penros Space or the Penrose Staircase, you will be trapped forever and unable to get out. "What kind of trouble is this?, how is it possible?" Song Zhe said in disbelief.

"Some people say that Penrose space is four-dimensional, and it is an endless loop. "Isn't the world we live in a three-dimensional space, where points, lines, and surfaces constitute the world? Song Zhe asked, although he was not very proficient in this aspect, but after being with Feng Ming, a "great scientist", for a long time, he knew a little bit about it.

"You're right, it's true that the Panlos theory cannot exist in the space we live in, it violates the laws of this three-dimensional space. Feng Ming explained.

"So, it's a rebuttal. Feng Ming nodded. "Then since it's a refutation, why are you studying it, are you able to support it when you're full, or are you idle and have nothing to do?" "That is, you are sick and have not taken medicine, this is a disease, you have to be treated!" Song Zhe said a witty remark, but it caused Feng Ming's eyes.

"You play tricks on me again, and next time Lao Tzu will ask you to copy the scroll, and I will have your surname. "Gotta get it, I was wrong, you go ahead, I'll just listen, all right." "Song Zhe's biggest trick is to copy homework, he has always relied on Feng Ming to go to high school since he was a child, if Feng Ming is really provoked by him, his temper will come up, not to mention Tang Seng's tight mantra, even the Buddha's five-fingered mountain will not play much role in him, study well, willful!!" I was thinking, if Panloth's theory is not applicable to three-dimensional space, then four-dimensional space will be realized, or a higher dimensional space. "You may be true at what you say, but unfortunately you were not born in the same era as Albert Einstein, otherwise, you two would sit down and have a cup of tea and discuss, and maybe you will solve this world-famous refutation." Song Zhe continued, "But, Mingzi, I want to remind you of one thing, that is, we live in a three-dimensional space, although many scientists believe that the universe is a four-dimensional space with the dimension of time, but unfortunately no one can follow up, it is said that Einstein is the closest person to the four-dimensional space, however, he has been gameover." ”

"Stone, I warn you again, I'm not messing around with you. Feng Ming's serious face made Song Zhe's playfulness disappear. "Well, as an apology, I can tell you something about this Penros Ladder. "If there's a fart, let it go. Feng Ming urged, his face full of impatience.

The Dutch painter Moritz Escher is a well-known master of illusion, who makes full use of the "Penrose Steps" in his lithograph "Ascending and Descent", and also creates a circular waterfall in his work "Waterfall". You can pay attention to him, maybe he has some thoughts. ”

Feng Ming nodded thoughtfully.

Feng Ming's memories ended here, he opened his eyes and looked down at his feet again, "Is it really the Penros Staircase?" Feng Ming felt that his idea was really a little incredible. He thought about it again and again that this Penrose ladder could not exist in three-dimensional space, and that Penrose's refutation could not appear in three-dimensional space, but if it was placed in a higher-order space, the Penrose ladder could be easily realized. So, after such a calculation, is this dark space where he is located a high-dimensional space? "Four-dimensional space!" Feng Ming seemed to know something, and couldn't help but shout. It is not that he says that this is a four-dimensional space without evidence, but in this space, he has no concept of time and does not feel the passage of time at all, and this vision reminds him of the four-dimensional space, if the three-dimensional space is a world composed of points, lines, and planes, then the four-dimensional space is a one-dimensional imaginary axis - time - added to these three basic conditions. "Yu Ji, what you said is to use the Panloth Stairs in the four-dimensional space to imprison me, no wonder you are so confident, sure enough. ”
