In just a few minutes, I reviewed the cosmic history of the brain world. And Ye Jingwen kept frowning and said:

"What are you looking at? Do you see what's coming? ”

I couldn't help but laugh and said:

"Interesting, really funny."

"What's interesting?" Ye Jingwen couldn't help but ask.

I glanced at Ye Jingwen and said:

"I said, Miss Ye, if you were given a chance to create the universe, how would you create it?"

Ye Jingwen was stunned for a moment and said:

"Why do you ask this...... I don't know? ”

I laughed and said:

"Why don't you think about it with your poor knowledge of physics?"

Ye Jingwen thought for a while and said:

"Hmm...... The universe came out of the Big Bang at the singularity, right? So, I'm going to make a singularity first. ”

I shook my head and said:

"Wrong, very wrong."

Ye Jingwen's eyes widened and said:

"Why?"

I laughed and said:

"The reason is simple. Making a singularity, then, how to define the concept of 'manufacturing'? The so-called manufacturing is to assemble or process according to certain laws or methods. But before the universe was formed, there was no space and no matter, so how to define the word manufacturing? ”

"What then?" Ye Jingwen asked puzzledly.

"Before the emergence of the cosmic singularity, there was theoretically a background, that is, the quantum fluctuation background, and that layer of background can be understood as a wall of physical laws, physical laws, and naturally there is no concept of time. The singularity of the universe is the random occurrence of quantum fluctuations, and this randomness has nothing to do with time, you can understand it as a kind of 'emergence'. ”

I explained without hurrying.

"Hmm...... And then what? Ye Jingwen asked. Isn't it okay to define it according to the laws of physics? ”

I shook my finger and smiled:

"That's not going to work either. First of all, the laws of physics...... There are almost infinite cosmological constants that can be allowed to exist. For example, if there are many universes, the Boltzmann cosmological constants of different universes can be different, for example, Planck's constants can be different, such as the speed of light is constant. So, before you create the singularity, you have to determine what kind of physical laws you want to make a universe. If the singularity is a seed, you have to give the seed a genetic code before it grows the way you want it to be. ”

Ye Jingwen thought for a while and said:

"So...... Just try again and again? If one doesn't work, let's have another one? ”

I nodded:

"Of course this approach works. But the problem lies in the more basic places. To define the laws of physics, you have to have a mathematical system. I'll give you an example, you can define the speed of light as 300,000 kilometers per second. But, what is thirty? What is One? What is two? What is the essence of mathematics? How do you define mathematics so that the system that created the universe understands mathematics? You have to define one, two, and more numbers to build the whole mathematical system before you can construct the laws of physics. In other words, mathematics is more basic than physics. But the problem is that at present, there is no mathematician in the whole world of mathematics who understands what the essence of mathematics is. Why does one exist? Why do there exist? These seemingly essential things are the most difficult. ”

Ye Jingwen's eyes became more and more confused, she tilted her head, and said:

"So what should I do? If you even ...... math If you can't define it, then the quantitative thing is completely inadequate? ”

I smiled slightly:

"That's right, from that point of view, in terms of quantity, it's impossible to define. So, we have to frame mathematics from the perspective of sexuality. ”

I continued:

"Mathematics is first an axiom, then a theorem, and then a law, such as Piano's axioms, which are essentially a set of mathematical axioms that humans empirically acquiesce in and are self-evident, and we have no way to ask why 'the straight line between two points is the shortest'. Because that's what axiom, that's what experience tells us. Of course, the earliest research in mathematics started from geometry, and before Newton, all the mathematical methods used by scientists were basically geometric methods. But there is one of the most essential and ridiculous questions about the geometric method, that is, what is ...... 'point'? ”

"What is a 'point'?" Ye Jingwen muttered.

"Yes. What is the definition of a point? I laughed, "Why is there such a thing as a 'point'?" Roughly understood, a 'point' is an infinitesimally small coordinate bit in mathematical space. But when it comes to infinity, mathematics tends to fall apart. For example, if 'point' is defined as the coordinates in space, then space must be defined first, but in mathematics, space is actually a set, and a set is made up of countless subelements...... So, a set is made up of points. Once you think so, you'll find ......"

"Rounded back?!" Ye Jingwen suddenly realized.

"yes, it's back." I nodded and said with a smile, "If you define a point in terms of spatial coordinates, there will be a circular argument cycle where you must first define space in terms of points. Therefore, the foundation of mathematics cannot be solid at all. If even points cannot be defined, then the axiom that the line between two points is the shortest, even less reliable. ”

Ye Jingwen scratched her head and said:

"So how do you define a point? No, I'm going crazy, I can't figure it out! ”

I smiled and said:

"Actually, at this time, I can use a philosophical way to characterize the 'point'. The point is 'existence'. ”

"But...... What is Being? Ye Jingwen muttered, "Oh my God, I'm going crazy!" The foundation of mathematics has become philosophy? If this continues, will it become metaphysics?! ”

I laughed and said:

"It's almost. I can characterize the concept of existence as two things: first, 'comparability' is the basis of existence, and second, all are equal to one. ”

"Well, I'm starting to get curious, I don't know what that means?" Qin Shuya stepped forward with a smile and asked.

I laughed and said:

Let's put it this way, if there is no external objective world, then there is no self, and we can't see the back of our head and our face, so the so-called self, in fact, from a subjective point of view, is just an external environment that is constantly moving, so if there is no external environment, there is naturally no self. It's like if there is no comparison between two chopsticks, there is no distinction between left and right. Without apples, there is no comparison between apples and bananas. Comparability is the foundation of mathematics. This is a property that is more fundamental than sequences. Only when it is comparable, can there be a distinction between one and two. ”

Qin Shuya thought for a while and said:

"Well, I guess I understand...... But what does it mean to be all equal to one, and to be all? ”

I stretched out my hand and pointed to the window of Hilbert Space and said:

"You see, these are two nuclei in the universe that are moving in opposite directions, and they differ in charge, mass, radius, spin, magnetic moment, electric quadrupole moment, cosmology, statistics, etc."

Two nuclei appeared in the window that showed a certain angular motion in different directions, but under my simulation, the information of these two nuclei changed.

"But what if I slowly adjust the basic physical quantities of these two nuclei, such as charge, mass, radius, spin, magnetic moment, electric quadrupole moment, symmetry, and statistics?" I laughed.

Ye Jingwen, Qin Shuya and the others held their breath and watched quietly as the two atomic nuclei in the picture began to gradually change the basic physical quantities, and there were changes.

As the basic physical quantities such as charge, mass, radius, spin, magnetic moment, electric quadrupole moment, symmetry, and statistics of these two nuclei tend to be the same, a magical picture appears.

The two nuclei began to get closer and closer, and their momentum, mass, and spin speed began to gradually become synchronized, and finally-

"Merge into one!" Ye Jingwen exclaimed. "Two nuclei, one?"

"Yes." I nodded, "Merge." When all the fundamental physical quantities of two nuclei are the same, they merge from two into one. And...... Even if 10,000 nuclei do this, they will eventually become one. It's called 'one is all, all is one'. Any single particle, you may think that there is only one, but in fact, it contains an infinite number of doppelgangers, but because all of their physical quantities are the same, they cannot be distinguished by outside observers. Only when there is an extremely slight difference in the physical quantities of these doppelgangers will a particle split into two. The basis of mathematics, why there are paradoxes in mathematics, why there is this infinitesimal concept, why there is a self-referential problem, why there is a contradiction when it comes to infinity...... In fact, the essence lies here. Infinitesimal points cannot be calculated and compared, and are destined to be alone. Mathematically, when we connect two points in a straight line, we actually default to the fact that the two points are not infinitesimally small, but stop the infinitesimal trend at a certain value. That's a small number. But comparability cannot be established without breaking this infinitesimal tendency of solitary oneness. ”

"One is everything......" Ye Jingwen muttered and repeated, "I can be considered to understand......

I smiled and said, "So comparability, in essence, is just to break the state of 'one is everything', and the essence of the universe is to transform between the state of 'comparability' and the state of 'one is everything'. And this state of flux is also the foundation of the brain world. This also explains the 'dualistic' worldview of the mental world and the 'virtual world' created by Tiran Shengxue. This includes the ability to predict the future. Can you understand? ”

Ye Jingwen said half-understood:

"I only understood a few ...... You've already involved mathematical logic, right? I also studied advanced mathematics...... But you're much higher on these levels. ”

"Look at this." I grabbed Alyssa Ye's wrist and guided her to look at the window of Hilbert's space.

Alyssa Ye raised her head and looked in the direction of my finger.

What emerges from the window on the inner wall of Hilbert's space is the cosmic structure of the mental world. From a distance, the cosmic structure of the brain world is a four-dimensional supersphere. The sphere of normal three-dimensional space is the most common shape of human beings, such as basketball or football, but the supersphere is a higher-dimensional sphere, because the human eye can only construct the restriction of information on three-dimensional objects by seeing the image of two-dimensional objects, and the hypersphere seen from the window of Hilbert space is just a three-dimensional projection of a high-dimensional sphere.

"This is a model image of the entire universe of the brain world." I said, "Look closely. ”

As my voice fell, an extremely strange scene happened.

Originally, it was still a supersphere with a complete structure, but suddenly there was a momentary tremor, and then, this lonely supersphere actually split into two!

"The universe is split!" Ye Jingwen exclaimed.

"Yes." I smiled and nodded. "The time of the first split of the brain world coincided with the first appearance of the Holy Snow of Tiran. In other words, because of the appearance of Tiran Shengxue, the 'full homosexuality' of the brain world was broken. ”

Ye Jingwen squinted her eyes and looked at the "new universe" that had split out, and soon, Ye Jingwen saw an incredible scene.

"Could it be that this new universe that has split out is the 'virtual world' that Tiran Shengxue created for us to compete?"

"Not bad. Exactly. I smiled and said, "It is by breaking the loneliness of the original universe that the 'full sameness' of the original universe has been created. And at the end of each game, Tiran Shengxue will adjust the virtual universe to the state of 'identical' with the original universe, so that the two universes will return to their original state, overlapping and becoming one. ”

"It's like...... Twins are the same. Ye Jingwen sighed.

"It's not so much a twin as a replicant. The picture you see now reflects the rational laws of the universe. I explained. There really exist two replicants in this world, their appearance, personality, growth environment, language behavior, action patterns, memory thinking, and people they interact with are exactly the same, then they can only be the same person. Otherwise, no matter how similar the two replicants are, there is still a slight difference in their nature. Moreover, if we narrow down to the microscopic level, the gap is still very large. ”

"It's really fun." William said with interest. "In other words, every time before the start of the game, the world will split into two, and after the game is over, the information will be completely assimilated and return to one, right? I don't know...... The world where the other team members are located is not the same structure? ”

I glanced at William and said:

"It may not be exactly the same, but there must be great similarities. The reason why the structure of the human body can maintain normal is, in the final analysis, related to factors such as the stability of the chemical bonds of elements such as hydroxide, oxygen, and carbon...... Not even hydrogen and oxygen atoms can't be formed at all, it's just a mass of electronic soup. Of course, this dichotomy of the world, other worlds may have, but it may not be as obvious as our world, but it should exist, which is enough to prove that the members of several of our worlds have used mobile phones to transmit information to each other in unlimited free space, don't look at such a trivial invention as mobile phones, which requires a certain amount of research on quantum mechanics to build. Therefore, it is certain that the physical laws of other worlds must also satisfy some phenomena of quantum mechanics, such as quantum entanglement...... The phenomenon of quantum entanglement, in essence, is also this principle of 'one is the total sameness of everything'. ”

"Oh? The essence of quantum entanglement is also one and everything? Qin Shuya asked with interest.

"At least that can be explained by that." I smiled slightly, "The so-called quantum entanglement refers to the fact that there is still some kind of connection between two particles that are extremely far apart...... Assuming that quantum mechanics is explained by some of the assumptions of string theory, quantum entanglement can be regarded as the vibration frequency of two strings is exactly the same, and when the vibrations of the two strings are synchronized, an extremely subtle connection will be established between them, which is faster than the speed of light, so even if they are extremely far apart, two particles in an entangled state are still connected, and they can even be said to be almost one. However, once someone observes these two particles in an entangled state, it is equivalent to disturbing the vibrational frequency of the two strings, breaking the frequency of their synchronous resonance, resulting in the splitting into two independent particles that are no longer connected, and the entanglement naturally ends. You see...... In a 'fully isotropic' way, the phenomenon of quantum entanglement can be explained from the perspective of resonance. Suppose that two particles become one when all the physical information is exactly the same. At this time, for these two particles, the concept of space does not exist. Because I am you, you are me, and we are one. ”

"So...... If the entire universe is considered as a huge particle, then Tiran Shengxue is a disturbing factor outside the universe, right? Qin Shuya seemed to have an understanding.

"It's almost understandable. Let's call a universe a 'cosmic acon' like a molecule and a quantum, Tiran Shengxue can break the entanglement state of a 'cosmic sub', divide one into two, and then make the information of the two worlds completely synchronized through secondary interference. This is the ability to intervene and interfere with the information of the universe, and this interference must be directed at all the particles of the entire universe, and it must be completed in an instant. ”

"So...... What is it to be able to interfere with the existence of the universe? ”

"It's very simple, if you want to compare the difference between A and B, you must need the referee or medium C to make the comparison. If there is only A and B in the world, A and B will not be able to realize the difference between themselves and each other. The difference between A and B can only be detected if A or B takes a mirror, or if an observer or referee C appears. Tiran Shengxue is this referee C, she is a mirror. If a universe is a cosmic sub, then Tiran Shengxue, who can interfere with this cosmic sub, can at least be regarded as a 'cosmic-level creature'. Tiran Shengxue is at least a universe, or even a collection of multiple universes. ”

"Cosmic-level creature ......" Ye Jingwen gasped.

"How does it sound like a fantasy...... And what about Miyoko? Ye Jingwen asked curiously, "What is Miyoko?" Tiran Shengxue is already a cosmic-level creature, no matter how you look at it, Meiyazi seems to be more powerful than Tilan Shengxue, so what is Meiyazi? ”

"To put it in cliché terms, Miyoko is at least a super-logical existence. Although this kind of thing is a bit like a vulgar fantasy novel when it comes out. I smiled wryly.

"Hyperlogical...... What does that mean? Ye Jingwen asked.

"It's very difficult to explain. For any creature that has logic, and is born by the mathematical logic of the universe, it is destined to be impossible to imagine what 'superlogic' is. Because we are, after all, logical creatures. I took a deep breath and said, "But...... Although we cannot imagine 'hyperlogic' for the time being, we can prove that our existing logical system is incomplete, or in other words, by proving how imperfect our current logical system is, so as to imply or indirectly prove the existence of 'hyperlogical'. In this way, the existence of Miyoko can be indirectly proven. ”

I said seriously:

"As I said before, the universe can be built by the laws of physics, and the laws of physics can be built by mathematical systems, and mathematical systems involve qualitative methods similar to philosophy. But if it is a hyperlogical existence, then even philosophical qualitative methods are insufficient to describe or cover it. Because our logic is 'limited'. Naturally, we who are limited to 'logic' are unable to imagine objects beyond logic. ”

"So this exists...... What should I call it? Ye Jingwen asked scratching her scalp. The source of all things? ”

"'Yes,'" I said lightly, "I'll call that state 'Keran' for the time being." ”

"Really? Is that still untrue? ”

I laughed:

"When you say 'no,' you're already comparing the two to the non-negotiable. When I say 'comparability', I mean a kind of referential removal. Of course, this is a bit of a twist, with your state of thought, it is not so easy to comprehend it for a while. But Miyoko is at least unreachable. As I said before, if you just use mathematical methods, you won't be able to get to the point where Miyoko is going to be. Just like infinity, as long as you give a number, it is destined to be smaller than infinity. ”
