Hearing the veiled woman's detailed explanation, Chu Yunsheng immediately understood what she was talking about. "You mean, the age of light that we used to live in is actually a kind of enclosed space, but the difference is that we are living in a three-dimensional enclosed space?" he asked.
"You can understand it that way." The veiled woman nodded her head and pushed the newly made model in front of him. "It's really troublesome to make a Klein bottle model with ribbons. Although it doesn't look like it, it's fine. It's just two Mobius loops glued together. There's no distinction between inside and outside. Then you can imagine that it has no boundaries, so the whole three-dimensional space becomes one.
But in fact, it can no longer be used to describe the enclosed three-dimensional space, because it's too simple. The real enclosed three-dimensional space can only be modeled by standing in the four-dimensional space. Just like we stand in the three-dimensional space to build a closed two-dimensional space like the Mobius loop, we need one more dimension to see the enclosed low-dimensional space. "
Chu Yunsheng was a little puzzled. "Since this bottle can't describe the enclosed three-dimensional space, then what do you want to use it to explain?"
The veiled woman made a gesture, stretched out four fingers, and said, "the fourth dimension, it is to let you understand more clearly that the enclosed three-dimensional space can only be done in the fourth dimension, because the real Klein bottle model also needs to be built in the fourth dimension. So what I want to tell you is that any enclosed space can only be achieved in a higher dimensional space that is at least one dimension higher than this space. "
Chu Yunsheng thought for a second and said, "I don't understand. Although I don't know much about science, I have heard that time is the fourth dimension, right? If that's the case, then we are not enclosed, at least we can still feel the existence of time. "
The veiled woman smiled and shook her head. "At the beginning, I have already said that time is not a dimension, it is just an axis. When the axis of time and the dimensional space are combined together, a meaningful world can be built.
So, for example, you can't say that there is no time in the two-dimensional plane, and their space also has a time axis. So, if the creatures in the two-dimensional space also treat "time" as a dimension, they will be ridiculous to think that they are already living in the three-dimensional space. In fact, the real three-dimensional space is the three-dimensional space that we see, with length, width, and height, not just the length and width of the space, and time.
And time as an axis, it exists in any dimensional space. It exists in the one-dimensional space, the two-dimensional space, the three-dimensional space, and even the four-dimensional space. The understanding of time in each space is also different because of the limitations of the dimensions. The laws of time that are adapted in the two-dimensional space cannot explain all the phenomena in the three-dimensional space. Similarly, in the three-dimensional space, the theory of time in the age of light also cannot explain all the phenomena in the four-dimensional space.
This kind of contradiction is like the understanding of a line in the two-dimensional space. In their understanding, this line can only bend left and right, but it can never cross itself, and it can never tie a knot. But in the three-dimensional space, it is very normal for a line to cross and tie a knot. "
Chu Yunsheng couldn't completely understand what she was talking about, but he knew one thing. The first thing he needed to do to practice the method of the ancient book was to break through the three-dimensional space barrier and establish a "channel" with Heaven and Earth Yuan Qi through another dimension. Then he needed to cultivate his own Yuan Qi and power. And this dimensional channel might be the fourth dimension that the veiled woman was talking about.
So he thought for a moment and said, "according to what you said, in the previous age of light, we were isolated outside the fourth dimension, right? So, what should the real fourth dimension be? "
The veiled woman untied the ribbon and held it in her hand. She didn't answer Chu Yunsheng directly. She pointed at him, and then pointed at Mu Xijun, who was sitting next to the campfire in the distance, and said slowly, "in fact, you have already felt it. You don't need to ask me. Your power and her power all come from the law of the fourth dimension. If you still can't understand it, I can give you another example.
In the two-dimensional space, we draw a circle, and then put something in the circle. For the creatures in the two-dimensional space, because of the circle, there is no way for them to take that thing out of the circle.
But when we use the extra dimension in the three-dimensional space to take that thing away from the sky, the creatures in the two-dimensional space will feel that the thing disappeared into thin air. They can't understand it. Their scientists will then come up with the conjecture of the existence of a higher dimension, and their history will give birth to many myths and legends, and even religions, but they are all used to explain the mystery of the disappearance of this thing.
Similarly, in the three-dimensional space, we can't take out the egg white and the egg yolk from the eggshell, but the fourth dimension can. It can appear in front of us without damaging any part of the eggshell, and then directly take away the egg white and the egg yolk. For us, the egg white and the egg yolk also magically disappeared from the eggshell. "
After Chu Yunsheng finished listening, he said seriously, "I can indeed feel the fourth dimension that you are talking about, but I can't take out the egg white and the egg yolk from the eggshell!"
The veiled woman was dazed for a second, as if she was shocked by Chu Yunsheng's words. She laughed and said, "you can't understand it so rigidly, otherwise, you won't understand anything. You can think carefully about where your power comes from.
If your body, the body that exists in the three-dimensional space, is compared to an eggshell, then the energy in the universe is compared to the egg yolk and the egg white, if there is no existence of the fourth dimension, can you "put" this energy into your body?
The result is obvious, you can't absorb this energy into your body! But using the fourth dimension, you can achieve this goal very smoothly. Simply put, it is still the example of the egg I just mentioned, but the process is exactly the opposite. In the fourth dimension, the egg white and the egg yolk are magically put back into the eggshell! "
Chu Yunsheng was shocked. What the veiled woman said now was very similar to the cultivation process he experienced from the ancient book. If there was no fourth dimension to break the three-dimensional space, he would not be able to refine Heaven and Earth Yuan Qi into his body, let alone Ben Ti Yuan Qi.
But soon, there was a new problem. He could feel the passage of the fourth dimension because of the ancient book, and the awakened humans could use it because they could "awaken". Then what about the rest of the people? Why couldn't they feel the fourth dimension?
Chu Yunsheng guessed, "so, have we been unsealed from the three-dimensional space and are now in the fourth dimension?" Chu Yunsheng asked.
"It has been unsealed a few years ago, but —" the veiled woman paused and looked at the faint light shining from the horizon, "whether it is the sealing of the space or the unsealing of the space, the process is far more complicated than the example I just simulated. It requires a complicated and changeable process, and it can even be repeated repeatedly. This is also the important reason why we still can't see the sun, and why there are so many monsters.
This is a bit more difficult to explain, but I can try, but whether you can understand it or not, it is up to you.
Let's take the two-dimensional space as an example. Think of it as a piece of flat white paper. If we fold it, or roll it up, in short, whatever you want, as long as it is three-dimensional and appears in the three-dimensional space, you can think of this process as the process of restoring it from the two-dimensional space to the three-dimensional space.
Then many places on the flat white paper that do not intersect on the three-dimensional space will overlap in the three-dimensional space. This kind of overlapping phenomenon, we can continue to infer that in the process of restoring the closed three-dimensional space to the four-dimensional space, there will also be some overlapping points in the three-dimensional space. So it is not difficult to imagine why there are many channels for insects and monsters to invade.
But this is the original appearance of the world. These overlapping points were originally created before the three-dimensional space around us was sealed, and now it is just restored to the last moment before it was sealed.
Similarly, it is the same for energy. They overlap and interfere with each other. In this process, some of the light from the sun will be shielded to another place. But energy is different from space. It moves very fast. After the overlapping barrier formed by the energy is completely unsealed, it will quickly return to normal, and then the sunlight will be restored. "Chu Yunsheng nodded his head.
He knew this from the ancient book, but because he did not understand the theory, he could not infer the specific date. The woman's explanation was more vivid and easy to understand, so he pointed at Mu Xijun in front of the bonfire and said, "according to what you said, once this process is over, we will completely enter the four-dimensional space, then will all human beings eventually be like her, through the" awakening "and feel the passage of the four-dimensional space? “
The woman did not answer him immediately. Instead, she put the veil back on her face, and after a while, she said, "this is all I can tell you. You don't have to threaten me with death anymore. I admit that the reason I told you so many things just now is indeed because I was threatened by you, but the question you asked now is already the core question!
Before I figure out your true identity, even if you kill me now, I won't say anything, because it's already a threat to our safety. Also, I don't know much about the core issues. My mission isn't this, so even if I tell you, it'll sound like something unintentional.
However, there is one thing I can tell you. I have also told the people in Zhiwu forest that the awakening you mentioned is not necessarily a good thing, and not being able to awaken is not necessarily a bad thing. In this world, whether it is three-dimensional or four-dimensional, there is no absolute good or bad thing. "
