Chapter 995: Everything and Superstrings

"While superstring theory is a beautiful mathematical formula that seems to fit some of the strong interaction data, the model has frustrating difficulties."

On this day, Yue Yuan came to the Institute of Physics again and happened to meet Yu Nanfeng, Liu Miyan, and a group of scientists who were committed to perfecting superstring theory. They were discussing the topic of superstring.

The speaker is Liu Miyan, a particle physicist, but that doesn't mean he can only study particle physics. Nowadays, human life expectancy is very long, so it is normal for some scientists to be proficient in several disciplines.

Of course, their main focus is still on the areas they are best at and have studied for the longest time, because there are so many branches of science and scientists' energy is limited.

Just like Liu Miyan, although he participated in the project to improve superstring theory, he mainly looked at and analyzed problems from the perspective of his professional particle physics.

At this moment, he was having a casual discussion with other people. It was not really a meeting, but more like a casual chat after get off work.

When Yue Yuan entered the research institute, Liu Miyan was talking, and Yu Nanfeng had his back to the door, operating something on the holographic screen in his hands, which seemed to be a structural model.

There are three other people, namely Dao Heiqi, Zhen Yafei and Shi Lifen.

The first two are important scientists who have perfected the superstring theory, while Shi Lifen is participating in the project here as a representative of life sciences.

Of course, there are definitely more than just these few scientists in the entire project. They are just a few scientists in one of the scientific research teams. Humanity has invested a lot in the entire large scientific research project, and one team has more than 100,000 scientists and researchers.

On weekdays, they are all in their respective jobs, contributing their wisdom to scientific progress.

Human civilization is a collective technological civilization. The development of science and technology cannot be achieved without the wisdom of millions of people, with scientists taking the lead, countless scientific researchers assisting, and interstellar governments controlling the direction of progress.
Seeing Yue Yuan coming in, the others showed no intention of stopping. Liu Miyan continued to talk. While he was talking, he called Dao Heiqi and Zhen Yafei to walk to Yu Nanfeng's side and pointed at the complex model floating in the air in the form of a holographic screen in front of them.

"First, the theory predicts too many particles, many of which have been proven wrong, and some of which are plausible. It's a bit like the graviton. Well, string theorists prefer to call it the quantum packet of gravity. The fact that the lowest vibration of a closed string corresponds to gravity and the lowest vibration of an open string corresponds to a photon is proven, and the theory of everything proves it is correct."

"Look here. This is the peculiar value and corresponding deformation formula taken by the theory of everything when describing the grand unified theory. This is a model that describes strong interactions instead of gravity or electromagnetic force, so it is actually a wrong statement. It was wrong from the beginning, because we are studying dark matter, and we must have gravity factors."

Several people nodded, all understanding what he meant. But the problem is that although this research must use the factor of gravity, it cannot ignore the other four fundamental forces and talk about gravity alone. This is the disadvantage of analyzing the problem from the perspective of particle physics.

In fact, what they need to do is to change this model into a model that describes phase transition, because in string theory, the interaction between gravity and light is necessary to form a unified field theory. Secondly, since the existence of superluminal particles has been confirmed, this model is desirable and is indeed a research direction.

Liu Miyan's resonant voice echoed in the institute: "Our speculation is correct. The theory of everything is actually all-encompassing. The theory of everything we have obtained is just a range solution we have obtained to solve the problem of negative matter and negative energy. In fact, it can also be used to explain dark matter and dark energy."

"The original theory believed that the dark matter-related theory was self-consistent only in 26 dimensions, but the theory of everything tells us that this is not the case. After 26 dimensions were introduced to explain dark matter and dark energy, the model collapsed. We found that it is 10 dimensions that are self-consistent."

"This fact proves that the universe should be ten-dimensional. If we can really master dark matter-related technology through it, well, at least this is something we humans have known for a long time."

Liu Miyan, who had just started talking, signaled Yu Nanfeng to add a few parameters he provided, and then continued: "For us back then, ten dimensions were too many, because our thinking was only used to considering four dimensions, three spatial dimensions plus a time dimension based on particle changes."

"But now it's different. Many of us have mastered the ability to observe microscopic high dimensions, and we have gradually come to understand some microscopic high-dimensional phenomena. As a result, the situation is different. We have discovered that there seems to be another path to the answer, although no civilization has ever walked this path. Oh no, maybe the Awakener has walked it."

Because the third-person perspective consciousness of human beings connected to the observation equipment comes from the awakener, this is something that all human scientists know, and Liu Miyan did not explain in detail.

At this time, Dao Heiqi saw that Yu Nanfeng had finished modifying the model in front of him, so he pointed to the data representing dark matter in the model and took over the conversation and said: "As we all know, space has three dimensions: length, depth and breadth. Any object in the universe, from insects to the sun, can be described by these three dimensions. But if we want to describe the age of insects or the sun, we need to add an extra dimension: time."

"In ancient times, we always thought that we could use these four physical quantities to describe the entire universe and everything in it, but in fact, this is not the case. This has been proven."

"And now we are going to study dark matter, which at first glance is a macroscopic substance like matter. So according to common sense, we should study it from the three macroscopic spatial dimensions. This is correct, but we have observation methods that other civilizations do not have. We can interpret it from a microscopic perspective, and I have always believed that the most critical point of this interpretation is the time dimension."

Dao Heiqi's meaning is very clear. Matter is macroscopic at first glance, but macroscopic matter also has microscopic structure, so theoretically, matter actually has more than three spatial dimensions, but the other dimensions are curled up, and the boundary between micro and macro is very vague. The same is true for dark matter, so humans can observe and study it from the perspective of microscopic high dimensions.

Dao Heiqi raised his hand and touched the holographic screen a few times, turning the entire picture into a three-dimensional projection of various spatial dimensions, and then continued: "I have always believed that the theory that the time dimension runs through the ten spatial dimensions is correct, but there is one point in this theory that should be modified, that is, the manifestation of the time dimension in each spatial dimension!"
