“Do you understand the Dragon Clan language?” Old man not at all answered Jiang Fei’s question directly.

“Understand it,” Jiang Fei replied, but he had worked hard in this area before.

“That’s good, I can’t express clearly in the language of humanity …” Old man said here and switched to using Dragon Clan to communicate with Jiang Fei.

Because Jiang Fei studied the Dragon Clan language for a while, the following words that old man said can be completely transformed into his own language and understood.

“What do you understand about space?” The old man asked, and the Dragon Clan language in his mouth was automatically translated by Jiang Fei, success himself.

“Space? I know that our Life is in a 3-dimensional space, maybe there is a biological Life in a higher dimension than us.” Jiang Fei said, but in his mind, it is not possible to have a biological existence in a higher dimension, because that Help guys have invaded this universe!

“By the way, Senior, is the 4th dimension of 4D space time?” Jiang Fei suddenly thought of a question.

“Of course not!” Old man shook the head, and then told Jiang Fei: “Time is a special vector, there is time in one-dimensional space, there is time in two-dimensional space, and time exists in every dimension of space! Time and space are 2 different concepts! “

“That’s it!” Jiang Fei nodded.

“Well, the relationship between time and space has been explained, so can you tell me the relationship between the various spatial dimensions?” Old man nodded, and then continued to ask Jiang Fei in Dragon Clan language.

“Relationship?” Jiang Fei froze, he didn’t understand what the old man asked.

“Well, let me tell you from the beginning.” Old man sighed, and then told Jiang Fei: “The so-called one-dimensional space is a straight line. If there are living things on this straight line, then in its perspective, all With only one point forward and backward, it can only move forward or backward. “

“And countless straight lines constitute a success plane, which is the so-called two-dimensional space. The creatures in it are no longer limited to straight lines, but can move freely up, down, left and right.” Old man continued.

“En! That’s true!” Jiang Fei nodded, the description of old man coincides with his knowledge in the World of Science and Technology. Although the term of the spatial dimension of Dragon Clan is not the same as that of the outside world, it also corresponds to each other. Is a meaning.

“The 3D World of our Life is actually made up of countless planes. After layering the 2D Worlds together, we will construct the 3D World of success.” Old man said here and took a look at Jiang Fei then went on to say: “So you can imagine that 4-dimensional space is actually formed by the superposition of countless 3-dimensional spaces.”

“What does a 4-dimensional space look like?” Jiang Fei curiously asked.

“To talk about this, we have to start with our perception of space.” Old man said, paused here, and then continued: “I don’t know if you found out. Our observation of World is actually through descending Dimensionally. “

“What do you mean?” Jiang Fei frowned.

“For example.” The old man reached out and a light appeared in the air.

“This is a straight line, which represents a one-dimensional space. If there is a creature Life here, then in his eyes, there is only one point in front and one point in the back, which represents the creature in Life in one dimension. He can only see the point. “After the old man waved, the light in mid-air disappeared and replaced by a light wall.

“You see, this is a plane, which represents a two-dimensional space.” Then the old man waved his hand, and there were many patterns on the light wall, square and circle.

“If it is a creature of Life on this plane, in his perspective, these squares or circles are invisible to him, all he can see is a line facing him that’s all.” Old man waved again His hand, the wall of light disappeared, but replaced by a solid wall.

“We Life is in a 3-dimensional world. Now look at it from your perspective. What’s in front of you?” Old man asked Jiang Fei.

“A wall!” Jiang Fei said as it should be by rights.

“En! That’s right! But it’s also a plane! You can’t see anything behind the plane at all, because you are a 3D World person, so you can only see the 2D World plane.” Old Man said.

“No! I can see 3D objects, such as this ball!” Jiang Fei said and took a ball from the ring’s space.

“Oh, that’s just the answer that you’ve made up in the subconscious based on a lot of related knowledge that’s all …” The old man said to take the ball from Jiang Fei’s hands, and then he waved his hands, and the surrounding light instantly became Dim, at this point in Jiang Fei’s eyes, the ball left only a little round shadow.

“You see, after losing the contrast between light and dark, your brain can no longer calculate, the real image you see in your eyes is just a circle that’s all.” Old man said with a smile.

“That’s it …” Jiang Fei nodded. It turned out that the 3-dimensional World in his eyes was just a 2-dimensional image returned by his eyes, and the brain then calculated the supplementary results based on light and dark contrast and near, large, and small knowledge.

“So, a person in a dimensional space can only perceive the space he is in through dimensionality reduction. He cannot see the true face of the space he is in!” Old man finally concluded.

“So that’s how it is!” Jiang Fei nodded, no matter how fascinating the scenery in the picture, all the creatures in the 2-dimensional space can only see a straight line, and the colorfulness of the 3-dimensional World in the eyes of people It is just a splicing of pictures. Although this answer makes Jiang Fei lose some things, it is the case.

“So you understand.” Old man laughed, and then continued: “The so-called 4-dimensional space is the product of the stacking of countless 3-dimensional spaces. Of course, this kind of stacking is not as simple as trying to build a house with bricks. Adding up is still a 3-dimensional World. This stacking is structured together in a way that we cannot understand. People there can see through our World as we see through the essence of the 2-dimensional World; the World in their eyes is Consisting of true 3D images, and since we can’t observe the true 3D World, we have no way to describe their World. “

“Don’t our 3D World people even imagine what a 4D World looks like?” Jiang Fei asked.

“No!” Old man shook the head, then said, “But I found something interesting, which may help you solve some mysteries.”

“What’s interesting?” Jiang Fei immediately asked.
