After this period of research on the theory and application of extraterrestrial artificial gravity fields, Yuan Haochen felt from the bottom of his heart that human civilization's understanding of the universe is indeed too superficial

Gravity, for example, is not present around us all the time, but we cannot truly understand it. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

One of the ultimate goals of many particle physicists is to explain the mode of action of all four fundamental forces in a blanket of mathematical models (Grand Unified Theory).

Including the great scientist Albert Einstein, after publishing his most proud work, the general theory of relativity, he began his "dream of unification".

His "unification" is more than 30 years, and he will not rest until he dies.

In the era when Einstein had just established the general theory of relativity, weak and strong interaction forces had not yet entered the attention of scientists.

Einstein should have been quite optimistic about the prospects of the "dream of unification" at the time.

He may think, "Isn't it all right to be unified, if electromagnetic force and gravity are so similar, that they both work remotely and are inversely proportional to the square of distance?" ”

Regrettably, Einstein's "dream of unification" has not yet been realized.

Like Albert Einstein, the research work of the extraterrestrial artificial gravitational field theory and application research project team has encountered a barrier that is difficult to overcome.

Therefore, as soon as they learned that Yuan Haochen had returned to the Pacific base of the Interstellar Exploration Alliance, several members of the project team couldn't wait to meet.

"Although, we have not yet been able to detect the existence of gravitons. But in quantum theory, forces (or interactions) are carried (or conveyed) by particles. At present, in addition to the graviton, the carriers of the other three fundamental forces have been proven to exist. Moreover, string theory (annotated at the end of the article) also predicted the existence of gravitons. ”

[Carriers of the other three fundamental forces: electromagnetic interactions are transmitted by photons and exchanged between charged particles; Weak interactions are conveyed by particles called intermediary vector bosons and exchanged between leptons (in some cases between a lepton and a hadron); The strong interaction is conveyed by gluons; The gravitational force is conveyed by gravitons. 】

Although the project team still found no trace of gravitons after long-term experimental observations, Li Yueqing believes that gravitons should exist.

"Gravitational force is so weak compared to the other three fundamental forces that it is a difficult task to detect how it is exchanged between particles." Hathaway added.

Indeed, the difference in the relative strength of the four fundamental forces is enormous. The gravitational pull is so staggering that it practically plays no role in the interaction between pairs of particles or between several particles.

But of the four fundamental forces, gravity was the first to be scientifically studied, and Newton developed a complete mathematical theory to describe it. Gravity is a universal force that is closely related to the basic structure of space-time, and we should consider it as the most basic force. In an absolute sense, gravity is not weak – it should be said that it is the way it is. Yuan Haochen commented on their views slightly, and then looked at Bai Kairui, "Your research direction is different from everyone's, are there any new discoveries?" ”

Carrey Brad's belief that gravity is the epitaxy of the electromagnetic force between protons and electrons is not difficult to understand, and many scientists share the same view.

If the rationality of this theory can be confirmed, then the gravitational force and the electromagnetic interaction force will naturally merge into one, and the dream of great unification will be realized!

It's just that no one has been able to verify the truth of this theory with experiments and mathematical models yet.

"In the past few months, I have built 12 mathematical models in different directions, but I have not yet come to reliable conclusions." Carrey replied with a regretful face.

"Keep up the good work." Yuan Haochen encouraged.

"Guys, we've been struggling lately with our research on gravity." Yuan Haochen looked at everyone with a solemn expression and said, "Durunik, they have discovered the centaur alpha Aa planet. Although Angelina and her sisters have encountered great technical difficulties, they have basically figured out the working principle of the artificial black hole dynamical system. Indeed, our project team has been the slowest of all the project teams. ”

"But that doesn't mean people aren't working hard enough. At present, our scientific and technological strength and cognitive level are limited, and human beings are not yet able to stand at a higher latitude to explain these phenomena beyond human cognition at this stage, such as the causes of gravity. However, I believe that with the continuous development of human civilization, we will continue to break through the limitations of human understanding of the universe! ”

The atmosphere at the scene was a little dull, Yuan Haochen paused for a moment, smiled and cheered everyone up: "Don't be discouraged, even the problems that Einstein did not solve with his life's efforts, how can it be so easy to unravel the mystery." If our research work is successful, this achievement can definitely be recorded in the history of human civilization and shine through the ages! ”

"Thank you team leader for your encouragement, we will continue to work hard!!"

After listening to the boss's reassuring words, Li Yueqing, Bai Carrey, and Hathaway's suppressed emotions seemed to be soothed.

Yuan Haochen nodded and continued: "According to the observation of the operation mode of the alien artificial gravity system during this time. Although I can't explain how it works, I can basically conclude that extraterrestrial technology uses electromagnetic forces to change the magnitude and direction of the gravitational field, but it is not yet possible to explain the specific way in which they change it. ”

Hearing this, the three of them all showed a look of surprise on their faces.

"Team Leader, are you sure that the gravitational field is real?" Li Yueqing asked.

"Not bad! I think the gravitational field is real, although we can't explain how it works yet. Yuan Haochen replied with great certainty, "Alien civilizations may have already discovered the true meaning of the gravitational field, or they have simply discovered the way to change the gravitational field, just like Maxwell discovered the mystery of the conversion between electricity and magnetism." ”

"Do you think that alien civilizations have only just crossed the threshold of their understanding of gravity?" Hathaway asked, confused.

"I'm not entirely sure about that, I'm just guessing." Yuan Chen's pupils shrank, and after being silent for a while, he remembered a sentence: "I know what it is, but I don't know why, this is the embarrassment we have now." ”

(Recently, this part of the chapter is more brain-burning, and you need to spend more time and read it slowly.) Because only by solving these technical problems in general will human civilization have the ability to travel interstellar. (To be continued.) )
