After briefly digesting this comparison, Wang Ling looked at Bai Ming sharply, and said clearly: "What do you mean, I am a person in the three-dimensional space, you are a life in the four-dimensional space, and in my opinion, you should be a god?" ”

Bai Ming didn't deny it, took a few sips of tea, and smiled: "That's pretty much what it means, of course, not only you, but also the entire dimensional space, I am a god!" I don't belong to the same world as you! ”

"Cut!"

This kind of arrogant statement made Wang Ling angry for a while. However, in the face of the main master of the other-dimensional system, Wang Ling had to forcibly suppress his anger at this stage, gasped twice, and continued to ask: "What kind of space is the four-dimensional space?" ”

Under this question, Bai Ming put down the teacup, glanced at Wang Ling, lightly touched the tea set, and then moved his finger to the stone platform and gently pointed out a water spot: "What is this?" ”

"Tea." Wang Ling replied without thinking.

Bai Ming rolled his eyes and corrected: "I'm explaining the dimension to you, don't talk to me!" This is a point that represents a zero-dimensional space! ”

"Zero-dimensional space?"

"That's right, zero-dimensional space is just a point, there is no length, no width and no height, this is the lowest space."

After Bai Ming finished explaining the zero-dimensional space, he then pressed his hand on a point of tea and swiped it to the side for more than ten centimeters: "Let's talk about it, what is this?" ”

Wang Ling was also excited: "Line! In the order you explained, this should represent one-dimensional space, right? ”

"That's right!" Bai Ming replied: "Countless zero-dimensional spaces, countless points, forming a line, this is a one-dimensional space, with infinite length, but no width and height. ”

As he spoke, he dipped in some more water, and wiped it off from the side on the basis of that line, soaking a piece of stone.

This time, Bai Ming didn't ask Wang Ling again, and said directly to himself: "This is a surface, a two-dimensional space composed of countless lines, with length and width, but no height. I think you should understand this concept very well, and there is also a saying of 'two-dimensional animation' in your world, in fact, the picture that appears on the screen can be understood as a two-dimensional space. ”

Wang Ling nodded slightly, the current explanation has not yet reached the level of incomprehension.

Bang!

Immediately afterwards, Bai Ming suddenly slapped on the surface of the water, splashing all the tea on the tea set. And with this beat, Bai Ming had unconsciously constructed a three-dimensional phantom, and as soon as he raised his hand, a blue square appeared under his hand. Immediately afterwards, Bai Ming changed his hand, and his index finger was pulled up at the corner of the light plate, and the entire square surface of the light surface was heightened, and finally became a phantom of a blue cube.

After the cube was formed, Bai Ming explained: "This should be the best understanding for you, because you live here - three-dimensional space!" On the basis of the two-dimensional space, the height is extended, and the infinite extension is infinite, and there is infinite space, such as the infinite universe! ”

Wang Ling continued to nod, this basically didn't need to be understood.

But then, the incomprehensible came, after the three-dimensional space, Bai Ming continued to move, and at a point in the cube, he randomly pulled out a line. With the advent of this line, the original upright cube has changed, and one end of the line is connected to the other endpoints, forming a very irregular polyhedral shape. Moreover, this shape is not fixed yet, because the extra line is constantly moving under the swing of Bai Ming, and the shape of this polyhedron is also changed.

"This is the four-dimensional space I am in! On the basis of three-dimensional space, there is an additional time dimension, which greatly changes the appearance of the whole world, and has an essential difference from three-dimensional space, which is also much higher than three-dimensional space, and the scientific and technological civilization is also higher than three-dimensional space! Bai Ming explained proudly.

(Regarding the introduction of four-dimensional space, it has been said that this is wrong, and that a timeline cannot constitute a four-dimensional space.) But in fact, what is the composition of the four-dimensional space, we in the three-dimensional world, we do not have a definite correct statement, so there is no need to dwell on the question of right and wrong, just have a framework for understanding. ）

"Four-dimensional space ......" Wang Ling looked at this unpredictable four-dimensional space phantom, his brows furrowed as if he were twenty, five or eighty thousand, he really couldn't understand such a space.

Not only him, but even Mr. Li Dong was confused, looking at it in a daze, thinking hard, but it was hard to imagine at all.

Tanya and the others, who were listening silently on the side and didn't dare to speak, were also a blind circle, although they were originally the product of four-dimensional space technology, but after all, this product was based on the three-dimensional space world, and they couldn't imagine the higher four-dimensional space.

And Bai Ming didn't care about their current confusion, and stretched out his finger again, drawing a line on one endpoint again, connecting with other endpoints, and forming a more complex shape between movements.

"This is the five-dimensional space, a space even higher than ours! It's just that as I said before, it is difficult to understand the higher civilizations and spaces, and for the five-dimensional space, in fact, even we imagine and speculate, and we don't know much more than you. This extra line, some people say that it is speed, some people say that it is temperature, and some say that it is other concepts, and there is no actual conclusion. ”

Bai Ming explained leisurely, and after he finished speaking, another line automatically extended from the already complex shape, connecting with other endpoints to form an even more complex shape. Before he could explain, another line was drawn, and then another, and another, until the entire cube was connected and enclosed into a sphere, and then it stopped.

At this time, Bai Ming sighed and said to himself: "According to scientific theory, then there is the six-dimensional space and the seven-dimensional space...... In each dimension of space, there will be a higher level of civilization, mastering even more amazing technology. Some advanced civilizations are already enough to travel across the universe and interstellar travel; There are also advanced civilizations that have truly broken through the limits of life and are immortal; There are also advanced civilizations that have even broken through to an unimaginable level, creating life, celestial bodies, and even ...... at will Universe! For us, that kind of top-level civilization is really already a god-like existence! ”

When talking about these high-level civilizations, Bai Ming's face was full of longing, obviously very infatuated with that kind of high-level civilization.

And after the longing, he quickly returned to reality, shook his head and said: "Of course, we can't be sure if these spaces really exist, whether there are really those super-high-level civilizations, after all, with our ability, we can't touch the higher-dimensional spaces at all." However, since the four-dimensional space exists, it is possible that the higher-dimensional space really exists! ”
