From Almighty Scholar to Chief Scientist

At this time, what Lin Xiao has to do is to find out the original function of the graviton in this three-dimensional space.

This is a slightly complicated indefinite integral problem. Of course, in Lin Xiao's hands, this complexity can become simple.

And with the completion of this step, he saw an astonishing result.

After the integration, the graviton, let’s call it the graviton in the four-dimensional space, is actually related to his previous equation.

Lin Xiao's eyes showed surprise, and then he was relieved.

"So, the gravity in the three-dimensional space is actually the shadow of the four-dimensional graviton in the four-dimensional space..."

"And the graviton-like thing I predict in the standard model of multidimensional field theory is its shadow."

The tone of his statement meant his affirmation of the result.

Just like the shadow of a person, it belongs to the projection of a three-dimensional object onto a two-dimensional surface, and the projection of a four-dimensional object is naturally projected onto a three-dimensional surface.

"It's just that, because it involves high-dimensional particles, it makes our observation difficult."

"Then, this is a good solution."

A smile appeared on Lin Xiao's face.

Once, he used low-dimensional to spy on high-dimensional, but now, he even found the connection between high-dimensional and low-dimensional.

At the same time, it is conceivable that which other particles also belong to this kind of projection?

Lin Xiao can easily think of one, and that is the neutrino.

After all, neutrinos are also difficult to observe, elusive and difficult to detect.

"Okay, let's not talk about these, let's sort out the papers first."

It just happened to bring an important result to his multidimensional field theory again.

Although his multi-dimensional field theory has been born for several years, there are not many people who have studied it, but there are not many major achievements like this.

So it's up to him, the founder, to drop another depth charge to revitalize this piece of water.

……

The review speed of "Physical Review Letters" is notoriously fast, especially the speed of rejection.

Of course, when the contributors are famous physicists in the world, they receive the manuscript very quickly.

Therefore, when Lin Xiao's paper was submitted, the editorial department quickly completed the review. First, they were extremely amazed by the content in it, and then published the paper that surprised them all in their next page. in a journal.

"Physical Review Letters" is mainly known in the physics community for its short length and important content. In a word, most of the papers are relatively short and concise, so there are many physicists who subscribe.

And when Lin Xiao's paper was seen by physicists, the entire theoretical physics community exploded immediately.

Connect relativity and gravitons?Also follow the standard model of multidimensional field theory?

Gravity is the product of four-dimensional space in three-dimensional space?The graviton in their universe is the projection of the graviton in the four-dimensional space?

These sci-fi-sounding words are not at all sci-fi in Lin Xiao's paper, and those sci-fi words basically come from their physics circle.

Therefore, Lin Xiao's paper also made all physicists feel crazy.

But from a mathematical point of view, no one questions the correctness of it.

After all, Lin Xiao’s derivations are all rational and orderly inferences, not based on additional theories for perfection, just like the description of gravitons in the Standard Model, which was originally determined by the physicists who originally determined the Standard Model. Introduced to improve the model.

As a result, a heated discussion was launched in the physics community, many famous physicists, especially some Nobel physicists.

"I have to admit that each of Professor Lin's papers is so amazing. As a physicist who studies quantum mechanics, I support Professor Lin's results."

"In any case, Professor Lin's thesis has opened up a possibility for us. I think we are now one step closer to the final answer to gravity. As for what is the final answer, it is naturally up to us." In the collider, see the fleeting gravitational interaction force. 』

"Oh, my God, the two upstairs are both Nobel Prize winners, I really learned a lot!"As a Ph.D. student in physics, I can only tremble. Of course, no matter what, Professor Lin will always be my idol.』

"Professor Lin is still very good, and he has made such a major achievement in multidimensional field theory. It feels like Einstein's theory of relativity. Einstein almost developed relativity to a position equal to quantum mechanics alone. level, and now Professor Lin is also doing such a thing, right? 』

"That's true, even though I can't understand even one of Professor Lin's papers"

Among the many speeches, there are quite a few who maintain a high opinion of Lin Xiao's paper, but in these speeches, a refuter who studies relativistic physics appears, and this relativistic physicist is also a well-known physicist. Although he did not win the Nobel Prize, he did not miss other heavyweight awards in physics.

"Hey, no matter how fancy you say, I don't dare to imagine the existence of gravitons. Although Professor Lin connected the existence of gravitons with the theory of relativity, from another perspective, wouldn't this still make people Does Relativity Completely Break Down? 』

Of course, other physicists also responded to this well-known physicist's speech: "Oh!Old Zeke, you can’t think like this, it’s just an equal sign now, but it’s inevitable that we won’t be able to find a perfect method to make the theory of relativity and graviton more harmonious?After all, they are all connected now, just like when you chase your wife, you also take your time, you have to connect first, and then slowly get closer.』

"My wife and I met in a bar. We got drunk together and then we got it all over. There is no such process of getting closer as you mentioned."

"..."

In this way, more and more physicists are discussing this matter, until finally, the physicists who study quantum mechanics are very convinced of Lin Xiao’s result, but for those physicists who study the theory of relativity, they Although they recognized Lin Xiao's thesis, they still said that they would still not believe the result if there was no experimental result to prove it.

As for the experimental results they want to see, it is natural to directly or indirectly observe the existence of gravitons in the experiment.

And this is the most critical point in this matter.

Chapter 388 The Arrival of Witten

"Professor Lin, I have read your paper, first of all, please let me express my admiration for your mathematical skills."

When the physics world was once again in shock, Lin Xiao received a call from the United States.

The caller was Edward Witten, the founder of M theory.

Lin Xiao was a little surprised by Witten's call. Of course, he also knew that it must be because of the paper that he called to communicate with him.

After hearing Witten's first words, Lin Xiao couldn't help laughing and said, "Haha, Professor Witten is being modest. You are also a winner of the Fields Medal."

"I don't need to talk too much about these problems. Anyway, after studying your multidimensional field theory many times, I haven't found that you can perform such delicate deformations at all. The only one who can find this kind of connection is you, Professor Lin. .”

Witten said.

Indeed, as Witten said, Lin Xiao's thesis is based on past theories, and to do this, one needs to have a keen sense of knowledge and a sufficient amount of knowledge.

Without these two, it is obviously impossible to do this, so this is why Witten admires Lin Xiao.

Otherwise, if it was easy to do, Lin Xiao's achievement would probably have been discovered by other physicists a long time ago.

This is like Maxwell's equations. The first version of the equations produced by Maxwell was composed of [-] equations, including [-] variables, so even if the things in it already existed in the academic world, But it takes a genius mind to do it.

"Hehe, it's a great honor for me to receive such praise from Professor Witten."

Regarding Witten's praise, Lin Xiao smiled, and then said: "Of course, after talking so much, let's talk about why Professor Witten came to me."

"Well, it's actually like this, Professor Lin, I deduced some of the content in your paper, and then came up with some surprising results."

"Oh? What is it that even Professor Witten attaches so much importance to?"

Lin Xiao couldn't help being interested.

Witten said it was amazing, so it must be very heavy, right?

Witten said: "As you said in your paper, the graviton in the standard model of our three-dimensional world is extended to a four-dimensional form by means of integration, then if we do not integrate, but differentiate How about going down?"

"Is it differentiating?"

Lin Xiao thought about it, and was taken aback for a while: "Can it be differentiated exactly four times?"

"Yes, it is quadratic. After all, this function is not smooth. Therefore, if we follow the realistic intuition, after differentiation to the cubic, it is equivalent to changing from three-dimensional to zero-dimensional, regardless of the graviton in the zero-dimensional space. What will it look like, but why can we still differentiate next? It can't be negative one dimension, right?"

Witten joked again: "Or from zero to eleven suddenly?"

After all, the upper limit of the dimensional space of M theory is eleven dimensions.

However, Lin Xiao didn't understand his joke, but thought about other things.

After hearing Witten's idea, he related this method to the problem he was actually working on, that is, the Yang-Mills gauge field existence and mass gap problem.

The paper he produced was originally intended to serve this problem.

At this time, Witten's question gave him an idea.

That is, what if he also uses the form of continuous differentiation to analyze the gluons and quarks in the strong force?

His distraction caused Witten to call out in doubt: "Lin?"

"Oh!" Lin Xiao came back to his senses, and then smiled: "Witten, I know what you mean, what you want to say is that the result of continuing to differentiate is the string you dream of, right?"

Witten said: "Yes, it's strings... To be honest, this differentiation process is really difficult. If I didn't refer to your integration method, I don't know how long it would take-of course, it is precisely because So, I think that's the string, because the end result, it's so simple and beautiful, it's like I'm seeing the string in digital form."

Lin Xiao pondered for a moment, Witten's idea also made him very interested, and he also supported Witten's idea, after all, for this person, discovering strings is of great significance.

Although in this regard, he has to say sorry to Witten, because he had already found the decisive evidence to prove the existence of strings in the demonstration of wave coherent superposition equations.

Of course, Witten's idea also gave him the idea of ​​having more exchanges with Witten.

Thinking of this, he said: "Witten, I can't agree more with your idea. In addition, I also have some other ideas, and I want to discuss more with you, so... Do you want to come to China for a while? ?Now I invite you to be a visiting researcher at my institute so we can have more discussions."

Hearing Lin Xiao's proposal, Witten was taken aback for a moment, and then after a short thought, he readily agreed: "I think, I have no reason to refuse, and it just so happens that I can come to Huaguo for fun."

Lin Xiao suddenly smiled and said, "Then I welcome you."

……

In this way, it was decided that Edward Witten came to Dingguang Research Institute and became a visiting researcher at Dingguang Research Institute at the invitation of Lin Xiao, and it was also spread.

It seems quite normal, after all, academic exchanges, coupled with Witten's reputation, it is not a big deal to be invited to be a guest researcher, but the academic circles know that Lin Xiao's paper has just been published not long ago At this time, it turned out that Witten was going to discuss with him at this time. Could it be that they were going to do something big?

Of course, no one knows what sparks of wisdom will arise between a leader in string theory and a leader in multidimensional field theory, so we can only guess.

For the domestic physics community, Edward Witten's visit is also a matter of concern, and he will even conduct research at the Dingguang Institute for at least one month, which can't help but attract more attention. Dingguang Research Institute.

Some are envious, some are jealous. Of course, the Dingguang Research Institute has always been a big attraction, and there are too many lice and it is not ticklish.

In this way, in mid-April, Witten set off from the United States and came to Lin Xiao's Dingguang Research Institute.

"Witten, we meet again."

Seeing Edward Witten getting off the car, Lin Xiao greeted him with a smile.

"Forest."

Witten also smiled and nodded towards Lin Xiao, looking at Lin Xiao's still young face, his heart once again gave birth to those emotions, probably when he is all gray-haired, Lin Xiao will still be like this Are you young?

Afterwards, Lin Xiao didn't keep chatting with Witten. He didn't have too much formalism here. At least he wouldn't let people go through the process after sitting on a plane for more than ten hours, so he took Witten nearby first. Let him have a good rest for a day, and then go through some procedures, such as the ceremony of hiring Witten as a visiting researcher at the Dingguang Research Institute.

After that, Witten officially became a member of the Dingguang Research Institute, and he was the only foreign scientist.

At this time, the two finally had the opportunity to conduct academic exchanges directly.

……

"What? Lin, what you want to study is actually the problem of mass gap?"

When Lin Xiao said the problem he wanted to solve, Witten said in astonishment.

"Yes."

Lin Xiao nodded, "I think, current physicists want to really understand the strong interaction force, right? And this is exactly what I want to solve."

"And if we can unify quantum mechanics and relativity, then this problem, I think, will be easily solved."

"I buy it." Witten couldn't help but exclaimed, "If I hadn't come, I probably would never have thought that your purpose would be this."

Lin Xiao smiled and said, "No matter what, at least I have taken the first step."

"Yes." Witten nodded slightly.

In that paper, Lin Xiao has taken the first step. The theory of relativity has been involved with quantum mechanics, and the bridge in the middle is the graviton under the multidimensional field theory.

"So, Witten, what do you think about this?"

Hearing Lin Xiao's question, Witten began to think quietly, and after a while, he suddenly said: "It is still difficult to achieve the unification of the two and a perfect fit, but you You should know about progressive freedom, right?"

"Of course I know... Wait, what do you mean?"

Lin Xiao nodded slightly, and suddenly, he understood Witten's meaning.

Witten smiled and nodded at him, "Yes."

He knew that Lin Xiao had already understood what he meant.

Chapter 389 The method of unifying quantum mechanics and relativity

Asymptotic freedom is an important property discovered in the strong interaction for decades.

At the same time, it is of great help to physicists to further understand the strong interaction force.

Of course, this thing has already been discovered. If Lin Xiao studies it again, it will definitely be meaningless. After all, he has already considered it in the process of studying the Yang Mills gauge field before.
