Among the many "Kabila-Chiu spaces", why did you choose the "Kabila-Chiu space" with an absolute value of 6 Euler numbers?

Witten did not explain the reason for the choice in the first revolution of superstring theory, and he took this "unproven inspiration" directly to lead the second revolution in superstring theory, proposing five different versions of superstring theory.

These five superstring theories exist at the same time and are compatible with each other, and Witten named them "M theory".

In the early '90s, Witten wrote in his paper, "M can be understood as Mystery, Master, or Mother, depending on personal preference." ”

The academic community was shocked, and the IMU was particularly excited, and as soon as the brain was hot, the Fields Medal was awarded to Witten.

Then, the third revolution in superstring theory came, and British scientists proposed the concept of a ten-dimensional supergravitational theory.

But the problem is that no school of thought or scientist, including Witten himself, can give convincing evidence of the fundamental degrees of freedom of Theory M.

The key question is, which version of M-theory describes the universe and what is the ultimate meaning of cosmic mathematics?

Mr. Hawking's intervention has led to a state of chaos in the field of research, and the situation has become more and more complicated.

Because of the theoretical position of the Yang-Rice equation in high-dimensional space, Mr. Yang Zhenning and Mr. Mills have also mentioned some remarks.

Superstring theory is not only a theory that unifies gravity and quantum mechanics, but also a theory of elementary particles.

There are electromagnetic forces, strong forces, weak forces, and gravitational forces between elementary particles, so what kind of convincing theoretical system should be relied on to integrate the common principles behind these four forces?

Even Albert Einstein and Weyl were dug up, and almost all of the most famous physicists of the twentieth century were directly or indirectly involved in the debate of the century over the superstrings, the unity of forces, and the mystery of the universe.

Although Witten sits on the throne of the first person in superstring theory, there are many scientists who are not convinced by him, and scholars who question his theory will always question it.

"Kids, I seem to have gone through the textbook, and I'm disappointed that the situation is not much different now than it was thirty years ago, and we haven't made a substantial breakthrough. Witten said that he, an American scholar in his seventies, and a group of young Chinese scholars under the age of 40 were talking about his masterpiece, Theory M.

It seems that this theory has really become a difficult mystery to solve, and M is supposed to represent Mystery.

"If Mystery is solved, we'll be the Master because it's the Mother. Shen Qi said a rap, which was quite rhythmic.

"So?" Witten asked, knowing that Shen Qi's mind would always hide something new and unpredictable and exciting.

"Edward, first of all we must admit that the Cambridge team's conclusions in the Third Revolution were correct. Shen Qi said.

"Who's to say it isn't. Witten nodded.

Dr. Wei, who had returned from Oxford, finally found a chance to speak: "Hey, the Cambridge group has two strokes, and they have discovered that the ten-dimensional theory of supergravity is not a one-dimensional string, but a two-dimensional membrane. ”

"Who's to say it isn't. Witten smiled, he and Cambridge boss Towndson had a little-known love and kill past.

"Edward, the M in your M theory also has a hidden meaning, which is Membrane, right?" Shen Qi was well-informed, he had heard the story of Lao Wei and Lao Tang falling in love and killing each other.

"Uh-huh. Witten smiled in confusion.

The record in the canonical history of physics is that the American school led by Princeton led the first and second revolutions in superstring theory, and Witten was the leader of the flag-carrying and was the C-position.

At the beginning of the Third Revolution in Superstring Theory, the British School, with Paul Townsson at its core, actually repudiated most of the research results of the First and Second Revolutions.

This has also led to the current chaotic situation of superstring theory.

But the description of the wild history is different, and there is clearly a leg between the C positions of the two camps, Witten and Townsendson.

If M stands for Membrane in M theory, then Witten is a pioneer work that celebrates the British C-position.

It is the so-called 30 years in the east of the river, 30 years in the west of the river.

The international situation is changing, and the emperor takes turns.

Witten and Thomson are now seventy or eighty years old, Hawking has left the world, Yang Lao is in seclusion, and the godhead of several of the most famous basic physics gods in the second half of the twentieth century is still high, and in the twenty-first century, the younger generation has begun to dominate the world.

Shen Qi is the undisputed C-position among the younger generation of scholars, and the Chinese C-position put forward his opinion: "The two-dimensional membrane was discovered from the ten-dimensional supergravity theory, and can even be considered a high-dimensional generalization of the solution of black holes." ”

"Schwarzzid's solution to a black hole is a solution in three-dimensional space, while Einstein's equation is one-dimensional and can be solved. An interesting and interesting topic to consider is that there are two-dimensional surfaces equal to membranes distributed in ten-dimensional space, not points and strings. ”

"In other words, the question we urgently need to answer is, after using a one-dimensional circle and tightening the supergravitational theory of ten-dimensional space into a nine-dimensional space, what will happen to the membrane in ten-dimensional space?" Shen Qi asked everyone.

"Yes, what will happen?" the rest of the Chinese scholars said in unison, and under the guidance of Shen Qi's logic, everyone seemed to be getting closer and closer to the truth.

Rubbing their hands together with excitement, the faces of the doctors of physics are full of red light, and most of them have just joined the center within a few days, and they will witness the solution of a century problem in physics?

"Superstring theory applies to space within nine dimensions, while in ten-dimensional space, membranes are considered to be the basic units of elementary particles. After the space is raised by one dimension, the basic unit is also raised by one dimension, and the only constant is quantum mechanics, paying tribute to Einstein, Schrödinger, Bohr and Heisenberg!" Shen Qi raised his arms and shouted, history and today are closely combined to point out the direction of the future, and the souls of the great gods of physics are possessed to lead everyone to the truth.

"Don't forget Fermi and Dirac!"

"And Planck and de Broglie!"

The doctors stood in a row and raised their right arms spontaneously and uniformly, a very ceremonial scene.

Shen Qi added: "However, it is almost impossible to construct a theory with a two-dimensional membrane, which is also an important reason why superstring theory is in a dilemma. ”

Thump!

The doctors fainted, and the big moves were opened, so you told us this?

Only Witten was the calmest, he realized that what Shen Qi said was by no means nonsense, and after going around in a circle, he still needed to return to his roots in the end.

Sure enough, Shen Qi said: "Tracing back to the source, I think the source of the problem is to completely prove that the Kabila-Qiu Chengtong space with an absolute value of 6 Euler number is the best choice. This is because the trajectory formed by the movement of a one-dimensional string in space is a two-dimensional surface, and the topology of a two-dimensional surface is completely determined by the Euler number. ”

Another village!

The doctors asked like chickens: "How do you prove it?" Professor Shen, do you have a plan?"

"Brothers, I've said it all, is the next thing to be done by you?" Shen Qi recruited back a group of returnee elites, not onlookers eating melons, all problems have been solved by Shen Qi, what's the use of asking for this group of elite-level doctors of physics?
