Great Country Academician

How do you plan to prove that the free flow scale of dark matter or the corresponding mass can be decoupled from neutrinos to the motion distance of t=teq?

Hearing this question, Price Carter said without hesitation: "Of course, it is done through the density perturbation algorithm on a scale smaller than λfs. Do I need to prove it to you on the spot? I think it should be quite complete in the paper."

For an academic report, it is necessary for an audience to read the papers and contents of the report before the question-and-answer session officially begins.

If a question that has been successfully solved in the report document is raised on the spot, the questioner will be laughed at by everyone.

Especially the person in front of him came on behalf of Professor Xu.

His question, to some extent, represents the opinions and views of that person.

Lin Feng ignored Price's gaze and said calmly: "But have you forgotten that density perturbations on a scale smaller than λfs will be smoothed out and attenuated by the diffusion of particles?"

"Especially when calculating based on the Hubbard–Stratonovich transformation, at the critical point, the fluctuations appear in an extremely long range, much longer than the lattice constant. You are taking the continuous limit of the discrete lattice model and using a field with infinite degrees of freedom to describe statistics."

"This approach is indeed feasible in mathematics, but in physics, especially in microphysics. If the particles you discovered are really dark matter, then your calculation results should be λf=∫^teq/ti·υdt =∫^teq|ti·p/ap"

At the report desk, Price Carter's pupils suddenly shrank when he heard this.

Density perturbations on a scale smaller than λfs will be smoothed out and attenuated by the diffusion of particles

Damn it!

Why did he forget this? Why didn't he find it when he checked?

Shit!

How should he answer this question now?

Standing on the podium, the redness on Price Carter's face, which was originally due to excitement, instantly disappeared and turned pale. It was as if he was wearing short sleeves and sunbathing on the beach of Hawaii Island in the previous second, and was directly sent to the ice sheet of Nanjing in the next second. The whole person trembled involuntarily.

The thoughts in his mind turned urgently, and the ideas he could think of quickly passed by, but there was no possible way to solve this problem.

What is even more despairing is that for a person who is in a desperate situation, it is particularly difficult to stay rational.

The more anxious people are, the less they can think normally.

In the No. 1 lecture hall, the whole audience was silent.

Everyone's eyes were focused on Professor Price Carter on the podium, waiting for his answer.

Feeling the gazes of the crowd, a little bit of sweat squeezed out of his face. Price Carter only felt chest tightness, shortness of breath, and difficulty breathing, and even suffocated.

Under the podium, as time passed bit by bit, the people who were originally quietly waiting for answers gradually became agitated.

At this moment, anyone with a discerning eye can see that Professor Price Carter has no solution to this problem.

At least in the short term, it is unlikely that he will be able to come up with a solution to answer the question.

After all, this is an acceptance report meeting. Even if he suddenly finds a feasible method, there is no time for him to verify this method.

There is only one person in the entire academic community who can prove it to you on the spot after someone points out a "major defect" at a report meeting.

That person is not Price Carter. On the contrary, he is standing on the opposite side today.

In the front row of the lecture hall, Professor Alan Aspe wrote down a few characters in his notebook and said with a smile:

"The free flow scale or corresponding mass of dark matter can be calculated by decoupling neutrinos. It has to be said that this is indeed a very hidden problem."

On the side, Peter Goddard, the dean of the Institute for Advanced Study at Princeton, nodded and said with emotion: "The most important thing is that this is simply the value of the free flow scale of neutrinos determined by the neutrino transfer function, and it is also a fatal blow to the Kaldera dark matter."

"To be able to find such a tricky problem in such a short time, it has to be said that even in Princeton, there are probably not many people who can have this level."

Obviously, the "he" here refers to Professor Xu Chuan who is far away in China. Only he has such ability.

And the young man standing in front of the question at this moment is just carrying out his task.

Professor Alan Aspe nodded and said with some regret: "Indeed, this problem is too fatal to Professor Carter's theory and experimental data."

"It seems that the physics community still has a long way to go before it can truly discover dark matter. Hope may fall on the CRHPC organization."

After a slight pause, he continued: "Speaking of which, I thought the problem came from the field of quantum mechanics, but I didn't expect the biggest problem to appear in mathematics."

Although he is not a scholar at Harvard University or a professor at the University of Munich, as a physicist, Alan Aspe still hopes that dark matter can be confirmed as soon as possible.

After all, dark matter particles have been detected by the Large Hadron Collider, which is a huge leap for the development of human physics and even for the understanding of the entire universe.

But now it seems that unless Professor Price Carter and the team behind him can solve the problems raised by that person. Otherwise, the final reputation of this acceptance report meeting may not be very good.

After hearing this, Peter Goddard made a joke and said: "Maybe there is something wrong with the structure of the field of quantum mechanics? As a Nobel Prize winner, do you really not believe in yourself?"

Hearing this, Professor Alan Aspe stroked the beard on his chin, thought for a while and then said: "What you said makes sense. Let's send an email to Professor Xu to communicate after the acceptance report meeting. "

"Huh? Are you serious?"

Upon hearing this, Goddard glanced at his friend next to him in surprise and asked.

Alan Aspe spread his hands and said with a smile: "Why not, my dear Professor Peter Goddard, sending an email will not take me long."

"If Professor Xu also discovers structural problems in the field of quantum mechanics, then this proves that my guess is indeed correct."

"If he doesn't find it and I find it in the future, doesn't it mean that I'm better than him in the field of quantum mechanics?"

Peter Goddard thought for a moment, nodded in agreement, and said, "In that case, I'll write a letter. It just so happens that I haven't contacted him for a long time."

Hearing this, Professor Alan Aspe squinted over and looked particularly funny with his iconic mustache.

Meanwhile, on the other side of Eurasia.

In the headquarters building of the CRHPC organization in Taohualing, Huaguo Star City, and in the lecture hall of the Central Palace, noisy discussions also spread throughout the entire venue.

No one expected that the CERN acceptance report meeting on Katara Dark Matter collapsed halfway through.

The first scholar to stand up and ask a question gave Professor Price Carter of Harvard University a fatal blow.

This made the scholars participating in this remote video conference start talking about it. When did the physics teams of Harvard University and the University of Munich become so arrogant? A scholar who doesn't look very old can easily raise fatal questions about their research results.

Of course, some scholars in the venue recognized Lin Feng and knew that he had attended the acceptance report meeting on behalf of Xu Chuan.

For example, Edward Witten, who was sitting next to Xu Chuan at the moment, stared at the projected remote video for a while, then suddenly turned his head to look at his student and said.

"The free-flow scale or corresponding mass of dark matter can be calculated by decoupling neutrinos. This is indeed a quite hidden and critical issue."

“At first I thought his experimental data and theories came from the direction of quantum mechanics.”

After hearing Witten's words, Xu Chuan, who was staring at the remote video projection, turned his head, smiled, and said, "That's a problem from another direction."

Hearing this, Edward Witten was stunned for a moment, and quickly said: "What do you think is the problem in the direction of quantum mechanics?"

Xu Chuan thought for a while, and finally opened his mouth and spit out two words: "Collapse."

Hearing these two words, Edward Witten was stunned for a moment, and then he came to his senses and asked in surprise: "You mean the wave function collapses?"

Xu Chuan smiled and nodded, saying: "If there is no problem with my speculation, this is the largest one among his experimental data after the question just raised by Lin Feng."

"I see."

Witten nodded suddenly, understood and said with a smile: "It seems that the two of us have similar opinions."

He was aware of the problem with Professor Price Carter's experimental data, but he did not go into detail about the collapse of the wave function at the bottom.

Maybe if you give him some more time, he can follow the clues and find the most critical reason from the papers and experimental data.

But it is really difficult to find such deep roots in just a few days.

It has to be said that his student's research in mathematics and physics has far surpassed him.

Perhaps only something from string theory can help him win back the victory.

On the side, Pierre Deligne, who also came to the scene, frowned slightly, looked at Witten and asked: "What did you just say?"

Although he was influenced by Xu Chuan and Edward Witten, he had some understanding of physics. But it is obvious that he cannot keep up with scholars in these cutting-edge fields such as dark matter and quantum mechanics.

After all, he is in his early eighties.

Upon hearing Deligne's inquiry, Witten smiled and explained: "Some basic things in the field of quantum mechanics."

After a slight pause, he continued: "I think you should know very well that the wave function is the core function that describes the state of microscopic particles."

"Wave function collapse refers to the phenomenon that the wave function of certain quantum mechanical systems mutates after certain interactions with the outside world, and becomes one of the eigenstates or a linear combination of a limited number of eigenstates with the same eigenvalue. "

"This phenomenon can be used to explain why the value of a physical quantity measured in a single measurement is determined, although the value of each measurement in multiple measurements may be different."

"But according to Professor Carter's theory, the moment-to-moment and ubiquitous interaction between microscopic particles and the dark matter model is the main reason for the uncertainty and randomness in the movement of microscopic particles."

Witten briefly explained the problem in Professor Price Carter's experimental data.

To put it in the most popular language, Professor Carter established an EPD model for dark matter, but he directly applied the unconfirmed hidden variable wave function collapse theory in Bohm mechanics.

This is a big problem for the explanation of Cardra's dark matter at the quantum mechanical level.

Of course, it may not be as fatal as the first problem.

Because for the current physics community, the hidden variable wave function collapse theory in Bohm mechanics cannot be confirmed for the time being.

Even if someone raises a question from this aspect, Price Carter's research can only remain unconfirmed by questioning.

Just like string theory, it has no flaws in logic, mathematics and other aspects, but it cannot be confirmed by experiment.

At the same time, on the other side.

In the No. 1 lecture hall of the CERN headquarters building, with the passage of time and the increasing silence of Professor Price Carter standing on the stage, the venue has gradually become chaotic.

Exchanges and discussions are trivial matters. Many young scholars have already taken out their mobile phones from their pockets to take pictures and videos.

Obviously, today's acceptance report meeting has a 99.99% chance of failure.

Even if Professor Price Carter and his team from Harvard and Munich University can solve this problem in the future, that is a matter of the future.

At least now, this report meeting is hopeless.

And for the scholars who participated in the report meeting, isn't this another "epic"?

Just like Professor Andrew Wiles was trapped by a "small problem" for eight months before he finally solved the problem.

Not to mention others, even Professor Wiles once thought that his proof was wrong before he finally found the bridge to solve the problem.

Fortunately, he did not give up and finally made up for this defect.

However, compared with Professor Wiles, I am afraid that the physics community will be even less optimistic about Professor Price Carter this time.

After all, it was that man who gave his acceptance report a fatal blow.

Compared with Professor Xu, I am afraid that no one will think that Professor Carter standing on the stage at this moment can solve this problem, even if Harvard University and Munich University are behind him.
