Chapter 31 (1/2)
”Well, now let's talk about your symbol.”
Professor Mei finally got to the point.
He picked up his pen and drew an equilateral triangle on the paper: ”this triangle represents the space we live in.” then he drew an inverted equilateral triangle on it. The vertices of the two triangles are connected, ”this triangle represents another space. Now, although the two spaces are connected, they are not connected. Moreover, there is only one point at the connection of space.”
”Do you know the meaning of 'point' in mathematics and physics?” the professor asked himself. ”In geometry, 'point' cannot be defined. Trying to define a point will fall into the abyss of repeated definition and inverse logical definition. But in space, we can think of a point as a 0-dimensional object.”
”Zero dimension means there is no dimension, not even the lowest dimension. Remember, the singularity of the universe is not a point in the mathematical sense, the singularity is an arbitrary dimension, and it is not zero dimension.” the professor stressed, ”Matter and energy generally exist in all dimensions of the universe, but not in the 0 dimension. If the two triangles connect not a point, but an edge, we can't determine how they affect each other, because we can't determine whether the two triangles represent a plane or a three-dimensional, but we can be sure that there will be extensive differences between them But now, the two triangles are connected only through a 'point', which is a dimensionless space, and this point cannot pass through any matter. ”
”It seems that the two triangles will not have any connection. What is the meaning of their connection?”
At the critical moment, Mei tried to make his old habit of selling off.
Aoki reluctantly took a meaningless sentence: ”it's always meaningful to be together!”
”Yes, of course it makes sense.” the professor was probably happy that someone was listening to his theory, ”Because if they are separated, they will become two isolated universes, which is really meaningless. They are connected only through a 'point'. Although no matter can pass through, they are always one and belong to the same universe. As long as they are in the same universe, no two spaces do not affect each other.”
”Then how did they affect?” Mei Ziqing was not criticized by the professor because of her interruption. At this time, she also bolded up.
The professor said: ”as a living body, you should not forget that our universe also has' consciousness', which is similar to the soul called by metaphysicians. Consciousness has no mass and is independent of matter. We have it, but we know nothing about its principle. Only this kind of thing without mass can pass through the point of 0 dimension and reach another space.”
”Oh, I see.” Mei Ziqing cherished the opportunity to speak like a student, ”You just mentioned dreaming, which means that people's dream is also another real space. There is a connected 'point' between it and our real space, and only our consciousness can go to the dream through this dimensionless point. Therefore, when we dream, it is not illusory, but our consciousness crosses another space?”
”Well, you can understand it like that.” the professor seemed to be thinking about his words and how to make it easier for his students to understand, ”But dreams are still illusory for us, because our consciousness will not completely leave our body and go elsewhere. In that case, we will not wake up. Just like the quantum superposition state, when we dream, consciousness should exist in two spaces at the same time.”
”Of course, some people may be exceptional.” the professor blinked mysteriously.
Mei Ziqing obviously didn't understand this paragraph very well, but the professor didn't seem willing to go any further. Instead, he picked up his pen and added a vertical line through the vertices in the two triangles.
”If this symbol is regarded as an hourglass, this section of line undoubtedly represents the passing time. But the so-called passing is only relative to a single space. If the two spaces are regarded as a whole, you will find that the total amount of time will not increase or decrease.”
As he said, he picked up the hourglass on the table, put it in his hand, turned it upside down, and turned it back. The sand in the hourglass flows from one end to another, and then back to this end, but anyway, they are so small and will never change.
