"I need your help."

当听见爱德华·威滕说出这句话的时候，李牧是有些惊讶的。

Who is this?

M理论的创立者，超弦理论的大宗师，最有可能成为爱因斯坦后继者的物理学家，物理学家中最好的数学家，数学家中最好的物理学家，菲尔兹奖得主……

There are so many titles gathered on the head of this great god that it can be said that basically only others ask him for help, and it is impossible to see him begging others to help him, because no one can help him with his problems.

But now, he found Li Mu.

This also means that Edward Witten thinks that the problems he has encountered can be solved by Li Mu.

Li Mu was stunned for a long time before he said, "Professor Witten...... First of all, I'd like to say that I'm honored to have your trust, but now there's an obvious problem – if you can't solve it, I'm probably going to have a hard time solving it. ”

"......No," said Edward Witten, "my problem stems from my lack of understanding of Lee's unfolding style. ”

"And obviously, in the world now, you are the one who knows the Li Clan's unfolding style best, and I have no one else to ask for help but you."

Li Mu pondered for a moment, and finally said, "Anyway, Professor Witten, if you can ask me for help, of course I am willing to lend a hand, so can you tell me how I can help you?" ”

"I think it would be better if we met in person." Witten said: "Whether I come to you or you come to me, of course, for the sake of sincerity, I think it would be better for me to come to you." ”

"And before we officially meet, I will send you the problems I have, and when we meet, we will discuss them, what do you think?"

"If you agree, I'll buy a ticket to China in two weeks."

Li Mu smiled: "This is probably not necessary, tomorrow I will go to Oxford University to become Professor Wiles's graduate student in mathematics, so if you come to China by then, you will definitely not meet me." ”

Witten was stunned for a moment: "Mathematics graduate ......"

Li Mu's words caught him off guard, and he suddenly remembered that the young man on the other end of the phone hadn't even graduated yet, and was still just a student.

He had even publicly expressed his willingness to accept Li Mu as a student before......

In the end, he couldn't help but sigh: "I don't know what else that Wiles guy thinks he can teach you?" I actually accepted you as a student......"

哦，忽然想了起来，听德利涅讲过，李牧之所以愿意做怀尔斯学生，很大程度上是因为怀尔斯赠送了他一支非常具有纪念意义，并且还很珍贵的钢笔，而那个时候的李牧，也方才完成了冰雹猜想的证明而已，还不像现在这样，震动完了数学界后又跑过来把物理学界给搅得天翻地覆。

That old boy's luck ...... That's really good.

轻叹一声，随后他说道：“那就，我订两个周后前往英国的机票，到时候咱们就在牛津大学进行讨论？ ”

But Li Mu didn't agree immediately, and after a moment of silence, he said, "Why don't we set the time for a month." ”

"In a month?"

Witten was stunned, "Why?" ”

“一个月后我将会前往CERN，召开一次关于李氏展开式的报告会。 ”李牧说道：“报告结束之后，我们就可以在CERN讨论你的问题。 ”

Hearing Li Mu's words, Edward Witten was stunned.

Li Mu was about to hold a report meeting on Li's unfolding, which immediately attracted his attention.

He asked in surprise, "Lee's unfolding report meeting?" ”

God knows how long the physics community has waited for this presentation.

At least to some extent, physicists around the world have been looking forward to Li Mu's paper since it was published.

And they are looking forward to the stars and the moon, and they are finally waiting?

“当然确定。 ”

Li Mu affirmed this matter.

A month is the deadline he gave himself.

他要在这一个月内，将李氏展开式下标准模型的问题彻底解决掉。

当然他也不是无的放矢，之前联想到了逆向量子统计方法之后，他的研究就有了巨大的进步，这么多天的时间过去，他也已经逐步找到了关键点所在。

The day when the problem is actually solved, we can already look forward to it.

"I see, then do what you said, and in a month, we'll discuss it at CERN." Witten said: "Of course, I will not be absent from your report, the entire physics community has been looking forward to this day for a long time, and I believe that day will be a feast for our physics community." ”

Li Mu smiled: "Maybe." ”

"Okay, let's stop here, I'll send my question to your email right away...... I very much hope that you can help me. ”

The phone hung up.

Li Mu sighed slightly, no matter what, Edward Witten was able to come to him for help, probably because of Edward Witten's obsession with proving the M theory.

Such an obsession makes such a top scholar willing to put aside his pride and seek his help.

He was perfectly able to understand that.

It didn't take long for him to receive a notification of a new email.

It was Witten's email, and he had already sent his question as an attachment.

After Li Mu downloaded the attachment, he opened it and saw that it was full of photos, and the content in the photos was a piece of scratch paper and the theoretical derivation process above.

Apparently it was Witten who took a picture of all his manuscripts, and then packed them and sent them over.

Li Mu didn't talk nonsense, so he looked at it directly.

Although he has not studied M theory in depth, he is very clear about the content of this theory, after all, it is one of the most famous theories in mathematical physics, and this physical theory, which has almost nothing to do with experiments, believes in absolute mathematical rigor.

Very much to his taste.

If it weren't for the fact that the current M-Theory explains superstring physics is perfect enough, perhaps he would have become a string theorist.

The first part is the process of combining Witten's M theory with Lee's expansion.

By using the Lee's expansion to avoid the non-perturbation problem, the M theory is perfected after combining it with the Lee's expansion.

The non-perturbation problem exists in all theories related to quantum field theory, and although the M theory does not belong to the quantum field theory, it is very closely related to the quantum field theory, so the non-perturbation problem also exists in the M theory, and restricts the M theory from becoming the ultimate theory that truly unifies all physics.

After all, as the ultimate theory, you have to be able to describe all the phenomena.

It's like a scholar once ridiculed superstring theory, which claims to be the ultimate theory, but can't even describe the theory of black holes.

Although it didn't take long for string theorists to describe Hawking's radiation theory in string theory, and even to derive the theory of relativity.

This is a kind of backward compatibility.

It's just that so far, superstring theory can describe very few "subordinate theories", like a pavilion hanging high in the air, supported only by a slender wooden stick.

“…… Therefore, if you want to prove Theory M, in addition to directly finding the existence of 'strings' and being able to prove its correctness, you can only prove it by indirect methods such as discovering additional dimensions......"

"Either that, as we plan now, we can use Lee's expansion to make M-theory backward compatible with more low-level theories, and then realize the proof."

The more low-energy theories that are backward compatible, the more wooden sticks there will be to support the M theory, which was originally like a castle in the sky, and at that time, the academic community will naturally have to admit its correctness.

李牧眯起眼睛，一边看着一边沉思着。

He has always had a lot of respect for Theory M.

After formally proposing the Lee's expansion, he also considered using the historical expansion to improve the M theory.

And now it seems that Witten has completely taken care of this matter.

And has been pushed far behind.

So where exactly does the "almost unsolvable" difficulty he spoke of appear?

Li Mu was very curious about what the problem was, which could make Witten describe it with words like "almost unsolvable".

In this way, as he continued to read, in the end, the problem that Witten said was finally displayed in front of Li Mu.

After reading this question, Li Mu was a little silent.

With a glance, Witten also made a note below: [As you can see, no matter how I deal with it here, and how I change the calculation method in front of me, here the mass always becomes positive infinity, as if it suddenly exploded! 】

Below, Witten wrote on another line: [To be honest, I'm a little scared now, I haven't told anyone about this problem I encountered, and now I only told you, I believe you should also know that there are only two possibilities for this situation, first, my calculation process is wrong, and second, the theory is wrong. But for the first case, I have verified it repeatedly I don't know how many times, and I have never found a problem with the calculation process, so now there is only the second possibility.

It's hard for me to accept that, so I hope you can help me find a third possibility, please! 】

The last "please", it can be seen that Witten is struggling to write.

But Li Mu understood very well.

At the same time, he also understood what Witten meant by "almost unsolvable".

"Theory is wrong", which means that Theory M is wrong!

This mathematical model, which was built by pure mathematical derivation and was considered mathematically perfect, is now mathematically flawed.

As soon as the news spreads, this theory, which has not been refuted due to its mathematical rigor, will immediately be labeled a "failure" in the physics community.

Of course, there is also the possibility that the Lee's expansion is wrong.

But this possibility does not exist, Li Mu has no doubt about it, not to mention that even Witten did not question the Li family's expansion.

Witten, having discovered such a startling error, would not have believed that it was the problem of Theory M in the first place, and he would have gone to test the Lee's expansion more.

And apparently, he determined that there was no problem with Lee's expansion.

The most likely mistake can only be Theory M, but he could not find the existence of the problem.

Why can't I find a problem with either one, but the wrong one could only be Theory M?

Because the former is only a mathematical method after all, it is only applied to theoretical physics, and mathematical theories are "real" and do not have "falsifiability".

Theory M, however, is a physical theory, and any physical theory will always have "falsifiability" that can lead to its overturning.

Therefore, Li Mu could imagine Witten's panic.

Moreover, this news is no less than an eighteen-magnitude earthquake for the entire physics community.

"Theory M is wrong" is, in a sense, no less than "the theory of relativity is wrong" and "quantum mechanics is a pseudoscience".

Any physicist would probably have gone crazy after hearing the news.

However, Li Mu didn't really care much about this.

他将自己的目光，移到了他的草稿纸上。

"Like, I've found something amazing...... Stuff? ”

This fatal problem encountered by Theory M seems to have become the inspiration for solving the problem he encountered?

With a little excitement and disbelief in his heart, he picked up his pen and began to deduce the truth that was already somewhat obvious.

"If you use the idea of inverse quantum statistics...... Yes! ”

"Whether it is the change of the mass of the W boson, or the concealment of the neutral concomitant particles of Zcs (3985), or the problems encountered by the M theory, there must be another factor that has been hiding at work."

【λφ^4+1/2σφ^2+c……】

Until the final ......

Li Mu looked at the solution he finally got in horror.

"Could it be...... New Fundamental Strength?? ”
