Voyage of the Stars

"While superstring theory is a beautiful mathematical formula that seems to fit some 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 superstrings.

The speaker was Liu Miyan. He was a particle physicist, but that didn't mean he could only study particle physics. Nowadays, human life span is very long, and it is normal for some scientists to be proficient in several subjects.

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

Just like Liu Miyan, although he is involved in the project to improve superstring theory, he mainly looks at analytical problems from the perspective of his professional particle physics.

At this moment, he was having a casual discussion with other people. It was not considered 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 hand, 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 perfected superstring theory, and Shi Lifen participated in the project here as a representative of life sciences.

Of course, the entire project must be more than just these few scientists. They are just a few scientists in one of the scientific research teams. Humanity has invested a lot in the entire large-scale scientific research project. There are hundreds of thousands of scientists and researchers in one team.

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

Human civilization is a group technological civilization. The development of science and technology is indispensable for the wisdom of millions of people. Scientists take the lead, with countless scientific researchers assisting, and interstellar governments control the direction of progress.

Seeing Yue Yuan walking in, few of them had any intention of stopping. Liu Miyan continued to talk. As he spoke, he called Dao Heiqi and Zhen Yafei to walk to Yu Nanfeng's side, pointing to the front and floating in the form of a holographic screen. Complex model in mid-air.

"First of all, the theory predicts too many particles, many of which have been proven wrong, and some of which are specious. Kind of like the graviton. Well, string theory scientists prefer to call it the quantum packet of gravity. In fact, the closed string's The lowest vibration corresponds to gravity, and the lowest vibration of an open string corresponds to photons. This has been confirmed, and the theory of everything confirms that it is correct.”

"Look here, this is the exceptional value and corresponding deformation formula used by the Theory of Everything when describing the grand unified theory. This is a model that describes strong interaction rather than gravity or electromagnetic force, so it is actually wrong. The statement was wrong from the beginning, because we are studying dark matter, and we must have gravitational factors.”

Several people nodded, understanding what it 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 to a model that describes phase transitions, because in string theory, the interaction of gravity and light is exactly what is necessary to form a unified field theory, and secondly, because the existence of tachyons has been confirmed , this model has merit and is indeed a research direction.

Liu Miyan's loud voice echoed in the institute: "Our speculation is not wrong. The theory of everything is actually all-encompassing. The theory of everything we got is just a range of solutions we got to solve the problem of negative matter and negative energy. In fact, it can also To explain dark matter and dark energy.”

“The original theory was that dark matter-related theories are self-consistent only in twenty-six dimensions, but the theory of everything tells us that this is not the case. After the factors that explain dark matter and dark energy are introduced in twenty-six dimensions, the model collapses. We found that On the contrary, the ten dimensions 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 that's the case. This is something we humans have known a long time ago."

Liu Miyan, who opened the conversation, gestured to 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 consider four dimensions and three spatial dimensions. Add a time dimension based on particle changes."

"But it's different now. Many of us have mastered the ability of microscopic high-dimensional observation and gradually understood some microscopic high-dimensional phenomena. So the situation is different. We find that there seems to be another path to the answer, although this path does not Which civilization has passed by, oh no, the Awakener may have passed by."

Because the human third-person perspective consciousness connection observation equipment comes from the awakener. This is something that all human scientists know. Liu Miyan did not explain too much.

At this time, Dao Heiqi on the side 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, 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 in 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 describe the entire universe and everything in the universe using these four physical quantities, but in fact this is not the case. This is something that has been proven."

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

Dao Heiqi's meaning is very clear. Matter is macroscopic at first glance, but macroscopic matter also has a microscopic structure, so theoretically, matter actually has more than three spatial dimensions, but 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 a microscopic high-dimensional perspective.

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