Ooh!

The emotions of hundreds of guests at the scene were ignited.

Hohoo!

The audience in the live broadcast room is becoming more and more active.

In the spotlight online and offline, Shen Qi continued his report: "According to Einstein's general theory of relativity, space and time have contracted under the action of gravity. Then, if the computational methods of quantum mechanics are forcibly applied to the general theory of relativity, there will be infinity that the renormalization method cannot handle. ”

"Look at this set of data, which accelerates protons to 99.99999999% of the speed of light, resulting in a resolution of 1,000 centiths of a meter. (1 kyo = 10 to the 16th power)

"If we test with LHC's 1 Beijing accelerator, a black hole will be formed...... Of course, they didn't, that's our speculation. ”

These pages may be a bit difficult for physics beginners to grasp, but they are a necessary prerequisite. Next, we welcome the protagonists of this report, string theory, superstring theory, and M theory. ”

Shen Qi explained very patiently, which was different from his previous reports.

From the Riemann conjecture to the Hodge conjecture, and then to the N-S equation, Shen Qi's report style is much the same, smashing a bunch of formulas out, whether you can read it or not is your problem, and I am only responsible for giving conclusions.

Today, Shen Qi has changed his style, he is more like a patient physics teacher, explaining a physics lesson to online and offline students that cannot be found in textbooks.

Why did Shen Qi do this, and broadcast live?

To attract fans, of course...... Oh no, on the one hand, there are popular science considerations, and on the other hand, it is more detailed, which is conducive to colleagues in the physics community to understand his ideas faster and better.

"The central idea of string theory is that elementary particles are not points, but strings with a one-dimensional space-extended vibrational structure. We can understand open strings as dry spaghetti and closed strings as macaroni. ”

So, we now answer the question on page 6 just now, which is that strings can eliminate infinity. In addition, the closed string transmits gravitational force, and the theoretical basis is as shown in the figure, if the closed string vibrates and transmits in this way, it will become a graviton that transmits gravitational force. It is this graviton, which is the combination of the theory of gravity and the theory of quantum mechanics, thus predicting gravitational waves. Gravitational waves have been confirmed, and more than a thousand top scientists have spent four months analyzing them, a project that has spawned a Nobel Prize winner in physics. Here, we would like to express our respect for the historic contribution made by Professor Nan. ”

In the course of his speech, Shen Qi expressed his respect for the predecessors in the physics field, and it was on the shoulders of the predecessors that the latecomers went farther and farther, getting closer and closer to the ultimate goal of physics.

It is generally accepted in the physics community that string theory was first proposed by Yoichiro Minami, a Japanese-American physicist at the University of Chicago, in 1970.

Interestingly, Yoichiro Minami's 1970 foundational essay on string theory was actually first presented to the public in 1995 when he published a collection of essays.

Later, the physics community confirmed what happened to Professor Nan, who wrote his landmark string theory paper in the spring of 1970, and then invited several physics leaders in the United States at that time to review his paper together in a secret cabin.

The bigwigs were shocked by the explosive theory of Nanbu Yoichiro, and they all admired, Xiao Nannan, you write well and beautifully, and you write croakingly.

Later, Nanfang went to San Francisco to hold a special lecture meeting, until he came to the lecture hall, and Nanfang opened his briefcase and suddenly found, Damn, where is my thesis?

At that time, there was no PPT, because Microsoft had not yet been established, and Nanfang was going to read the paper, but the paper was lost.

So Professor Nanbu reported his research results on string theory from memory.

Although only a few people have read the southern paper, these people are all physics bigwigs, very influential and authoritative. Coupled with the originality of Nanbu's string theory ideas at the time, and his good eloquence for reporting, Yoichiro Minami was widely regarded as the founder of string theory at the time, even if he did not find a paper.

He won the Nobel Prize in Physics in 2008, but the reason for the award was not string theory, but the spontaneous breaking mechanism of symmetry in subatomic physics.

Shen Qi continued his report: "Are you confused, why do you talk about gravitational waves? Actually, I don't think far, we think that if string theory contains gravity, then this theory is the ultimate unified theory that integrates general relativity and quantum mechanics. And from the prediction of gravitational waves to their confirmation, it proves that our unified thinking is correct. ”

Shen Qi paused for a moment to observe the situation at the scene, and he saw that the guests at the scene were listening to his lecture attentively.

Since no one has an opinion, let's go ahead.

"Superstring theory explains not only bosons but also fermions in terms of string vibrations, which is the difference between superstring theory and string theory. ”

"However, it is well known that there is a theoretical loophole in the theory of superstrings that include open strings. Shen Qi looked at the audience, where his theoretical physics team was sitting.

The superstring theory was founded by Schwartz, a physics professor at the California Institute of Technology, and his French student, Nanf, who perfected the theory of Raymond, a researcher at the Fermi National Accelerator Laboratory in the United States.

Then Edward Witten entered the field of superstring theory, and in order to study this thing, he specially invented a set of mathematical methods, and won the Fields Medal in an incredible way. That's why the physics world is wonderful.

Although Witten is known as the first person to theory superstrings, his reason for obtaining the promise is not superstring theory.

It is not that the Nobel Prize jury has any deliberate prejudices about string theory and superstring theory, but because this kind of profound pure theory is difficult to be confirmed by existing instruments and equipment.

And at the theoretical level, superstring theory does have some contradictions that are difficult to justify.

Witten was at the scene of the lecture hall of Yanda, and he was a member of Shen Qi's team.

For decades, Witten has been trying to refine the difficult parts of superstring theory and M-theory.

It wasn't until not long ago that Witten got some new inspiration, and his inspiration was confirmed and processed by Shen Qi, and the 17 physics doctors under Shen Qi were made into PPT form, which was about to be displayed in front of the world.

"To the suicidal pain of countless physicists who have studied superstring theory, if superstring theory were not in the nine-dimensional space, photons would have mass, which would contradict special relativity. In other words, as a result of the quantum swing, superstring theory suffers from a 'theoretical disease' of loss of coordination. In a regretful and sad tone, Shen Qi helplessly stated a stubborn disease that was difficult to solve in the academic world.

"This ......" The physicists at the scene were nervous, we came all the way here, Professor Shen, you will tell us this?

The netizens in the live broadcast room were frightened and didn't dare to post a barrage, what happened to this Nima?

Suddenly, Shen Qi's mental outlook became excited, he raised his arms and shouted, and switched to the next page of PPT: "Distinguished guests, science lovers, I would like to announce an exciting good news next, not long ago, our team finally solved the 'theoretical disease' in superstring theory through mathematical methods!
