Seven and a half p.m., CERN Auditorium.

After dinner, Pang Xuelin came to the first row of the lecture hall and sat down and waited patiently.

Cheng Xin sat beside him.

"Professor Pang, shouldn't they not come?"

Cheng Xin said with some worry.

Pang Xuelin smiled: "Don't worry, I have released the bait, as long as they still have the slightest concern about the future development of physics, they will come!" Until now, the physicists who have remained at CERN, and have not moved on to other fields of study, are scholars who truly love physics. Physics is something they have studied all their lives, Tomoko blockade shattered the holy grail in their hearts, and after knowing that there was no hope, they degenerated, went crazy, and numbed themselves with alcohol all day long. Now, they're told that there's hope for physics, and it's a wall-facing person who says it, and do you think they'd like to come? ”

Cheng Xin nodded a little ignorantly.

Although she is a major in aerospace engineering, she still can't quite understand this pure scholarly mentality.

Therefore, even with Pang Xuelin's assurance, Cheng Xin is still a little worried.

From time to time, she turned her head to the entrance of the lecture hall, waiting for someone to arrive.

After a while, Cheng Xin's eyes suddenly lit up and said, "Someone is coming." ”

Entering the lecture hall was a tall, thin man in his thirties with a pale face.

Seeing Pang Xuelin and Cheng Xin, the tall and thin man said, "You are also here to attend the report meeting?" Damn, those guards almost searched me like a terrorist! ”

Pang Xuelin smiled: "You also listened to Rupert's introduction?" ”

The tall and thin man said: "Yes, Rupert said that there is a wall-facing person who came to CERN, and he is ashamed to say that there is a way to contact Zhizi blockade, we just want to see who the wall-facing person is, and he dares to speak so loudly." ”

Seeing that the tall and thin man didn't recognize Pang Xuelin's identity, Cheng Xin, who was sitting next to Pang Xuelin, was just about to explain, Pang Xuelin patted her hand and said: "I also Rupert said, it is said that the person facing the wall is a mathematician, and he also said that physicists are a bunch of idiots, physics is pseudoscience at all, and only mathematics can save mankind!" ”

The tall and thin man was suddenly angered by Pang Xuelin, his face turned red, and he said loudly: "Where is that wall-facing person?" He talks nonsense, physics...... Physics is not pseudoscience, otherwise Zhizi ...... Why is Tomoko blocking our ion accelerators! ”

"Brother, don't get excited!" Pang Xuelin said, "I also came to the report meeting because that guy was unhappy, and now there is still a period of time before the report meeting, and he estimates that he will not be able to come over for a while, and we will refute him at the report meeting later." ”

Cheng Xin on the side couldn't help but roll his eyes, this guy is talking nonsense again.

The tall and thin man said: "Yes, I will refute him at the report meeting, by the way, this little brother, where are you?" I don't think I've seen you at CERN, have I? ”

Pang Xuelin's face did not change: "My name is Luo Ji, a doctor from the Department of Physics of Tsinghua University, I once made a wish to devote my life to physics, but after the blockade of Zhizi, my tutor returned to China to work on materials, I didn't want to go back, so I have been staying at CERN." ”

The tall and thin man said: "Okay, those guys are all traitors to physics, only those of us are really passionate about physics!" ”

Cheng Xin was on the side, glaring at Pang Xuelin.

Pang Xuelin's operation simply subverted his three views.

In the past, Pang Xuelin bullied himself, but he didn't expect such an honest person to bully him.

Pang Xuelin smiled and said, "By the way, brother, where are you?" ”

The tall and thin man stretched out his hand and said, "Princeton Boyle Baker, I'm a student of Professor Witten." ”

Pang Xuelin was slightly stunned, he didn't expect Witten to exist in this world.

He wondered, "What about Professor Witten?" How is he now? ”

Baker said: "The professor is okay, he is staying at the Institute for Advanced Study in Princeton now, anyway, even if his theory has a hadron collider, it will take decades or hundreds of years to be proven, and now that it is completely out of play, he will not count on it, and he will be able to engage in theory in Princeton with peace of mind." ”

Pang Xuelin nodded, and asked again, "Then why don't you go back to Princeton?" ”

Baker became a little excited again, and said: "Those idiots actually want to dismantle the LHC, and we, the scholars who stayed behind at CERN, have already decided, if anyone dares to dismantle the LHC, unless it is crushed from our corpses." ”

Pang Xuelin couldn't cry or laugh, and he didn't know if this group of people was considered a physical fundamentalist.

But what he needed was a group of people who were crazy about physics, otherwise he wouldn't have come here specifically to find someone.

As time went on, more and more people began to enter the lecture hall.

Most of these scholars looked quite haggard, and some even smelled of alcohol.

There were about sixty or seventy of them, most of whom knew each other, and when they entered the lecture hall, they chatted in low voices, sometimes scolding.

Cheng Xin sat on the side and was a little frightened, she didn't expect that these seemingly Svenwen scientists would be so terrifying when they went crazy.

Pang Xuelin sat in the first row, and Baker was in the way, and some people didn't notice his existence even if they knew him.

Seeing that the clock was about to point to eight o'clock, Rupert hurriedly walked in, he turned around, and said hello to most of the people present one by one, and then found Pang Xuelin in the first row.

"Professor Pang, everyone is almost here, didn't you say that you have a way to solve the Zhizi blockade? Now it's your turn to take the stage! ”

Rupert walked up to Pang Xuelin and sneered.

"Actually, I'm the one who faces the wall!"

Pang Xuelin smiled slightly, patted his face for a while red and white, and Baker's shoulder, which had fallen into a stupor, walked up to the report table unhurriedly.

The lecture hall suddenly fell silent, and everyone's eyes were focused on Pang Xuelin, and a slight discussion could be heard from time to time.

"He's the one who came up with the theory of Ponzi geometry?"

"You look so young!"

"I heard that I was in my twenties, and I used to be at ETO."

"Just this stinky guy, does he have a way to solve the Zhizi blockade?"

……

Cheng Xin looked at Pang Xuelin with some concern, judging from the performance of those physicists just now, he didn't have a good impression of Pang Xuelin.

In case he said something wrong today, with the current mental state of these physicists, Pang Xuelin may be guilty.

Pang Xuelin didn't seem to be aware of all this, and said with a smile: "Good evening everyone, it's a pleasure to meet you at CERN, I'm Pang Xuelin, who is facing the wall." All of you here are well-known figures in the world of physics, and your stay here shows that you still have a glimmer of illusion and hope for the future of physics. But what I want to tell you is that physics did not exist in the past, does not exist now, and will not exist in the future! ”

"What do you mean!"

"Physics doesn't exist anymore, so why are you still bringing us here?"

"Another sensationalist guy who wants to waste our time!"

……

The audience suddenly became noisy.

Pang Xuelin had to get close to the microphone and said loudly: "Quiet! Hear me out first! ”

Maybe Pang Xuelin's voice was loud enough to suppress the voices of everyone in the audience, or maybe Pang Xuelin's voice had some unknown power.

The audience gradually quieted down, and everyone's eyes were fixed on Pang Xuelin.

Pang Xuelin's tone was unhurried, and he said: "Everyone should have heard of the Science Boundary Organization, which is the ...... under ETO."

Many people in the audience changed their faces slightly.

Scientific boundaries is an organization developed by ETO in the academic community in the past, with the purpose of disrupting the scientific research of the earth, and many people present have intersected with scientific boundaries.

Pang Xuelin said: "People at the edge of science have spread the so-called SF hypothesis in the scientific community, that is, the shooter hypothesis and the farmer hypothesis, and I believe everyone here has heard of it. ”

"The shooter hypothesis describes it like this: there is a sharpshooter who makes holes every 10 centimeters on a target. Imagine that there is a two-dimensional intelligent creature living on this target, and the scientists in them, after observing their own universe, have discovered a great law: every 10 cm units, there must be a hole. They see the whims of this sharpshooter as an iron law in their own universe. ”

"The farmer hypothesis: There is a flock of turkeys on a farm, and the farmer comes every day at 11 a.m. to feed them. A scientist in Turkey observed this phenomenon for almost a year without exception, and then it discovered the great law of its own universe: every morning at 11 o'clock, food arrives. It proclaimed this law to everyone on Thanksgiving morning, but at 11 a.m. the food did not arrive, and the farmer came in and killed them all. ”

Cheng Xin looked at Pang Xuelin on the podium blankly, it was the first time she heard such a hypothesis, and these two hypotheses made her feel a chill in her heart.

Zhang Beihai on the other side pursed his lips, although the expression on his face did not change much, but from his eyes, he could feel that the other party's heart was not so calm.

There was an eerie silence in the entire lecture hall.

Pang Xuelin's voice continued: "These are two very vivid metaphors, many physicists because of the interference of intelligent sons in the collision experiment, the result is that there is no law to follow in the microscopic particle world at all, and even come to the conclusion that physics is uneven in time and space, and the result is suicide." I can only regret this, maybe they were right, but I personally don't agree with their suicide. ”

"I once had a friend who made a mathematical model of the Earth's evolution to simulate the evolution of the Earth's surface morphology in the past and in the future. This model combines biological, geological, atmospheric, oceanic, and astronomical factors, and he found that the earth has produced life, and life is also changing the earth, and the current earth environment is actually the result of the interaction between the two. If the option of life is removed, the Earth will lose its oceans, rivers and even the current atmosphere, and become as dead as Mars. ”

"Suppose we magnify the problem into the cosmic environment. The stars in the universe are like the sands of the Ganges, and there are countless of them. In the constellation Centauri, which is closest to our solar system, there is an intelligent civilization, so what I want to ask you is, how many intelligent civilizations exist in the universe? As long as these intelligent civilizations developed a million years earlier than our human beings, what heights can they reach today? Who would dare to say that the speed of light we have today, the three-dimensional universe we see today, is not the result of the action of life? ”

Dead silence!

Everyone looked at Pang Xuelin in amazement.

These top physicists on the earth suddenly felt that Pang Xuelin seemed to open a new world for them.

"So what I want to say is that physics is very likely to be inhomogeneous in time and space, and physics has never existed from the past, to the present, and to the future!"

At this time, someone in the audience said: "If you say this, then what is the point of us studying physics?" Isn't the classical mechanics system established by Newton, the relativity system established by Einstein, and the quantum mechanical system established by Bohr, Planck and others meaningless? ”

Pang Xuelin smiled faintly: "Who said that it is meaningless, everyone seems to have forgotten what tools these physics systems are built with, mathematical tools!" The collider is just a tool for us to explore microscopic physics, and without such a tool, wouldn't we have found a way to do physics research in other ways? Looking back at the 300 years of modern human history, the influence of mathematics on physics is everywhere. ”

On June 10, 1854, the mathematical genius Riemann published "Assumptions on the Foundations of Geometry" at the University of Göttingen in Germany, which shook Euclidean geometry, which had not been shaken for 2,000 years. Riemann believed that the foundation of Euclidean mathematics was only the quicksand of common sense and intuition, rather than the result of solid logical deduction. For example, Euclidean geometry says that the sum of the three internal angles of a triangle is equal to 180 degrees, a seemingly simple problem that has never been rigorously proven in the history of mathematics! And, if you're in a world of curved surfaces, this formula doesn't hold. Riemann made Newton's first epoch-making major breakthrough in 200 years, completely overthrowing Newton's principle of over-distance action, and he believed that force is derived from geometry, and force is only an inevitable phenomenon caused by the distortion of geometric structure. In the age when Newton had long been a god, what courage it would have taken to say such a conclusion! ”

"Riemann simplified all the forces of nature with the theory of multidimensional space; It is believed that electricity, like magnetism and gravity, is only the result of the bending of high-dimensional space. He proposed the concept of wormholes, and the Riemann incision is the simplest example of a multi-connected space. He describes gravity in terms of 'field' and 'metric tensor' to describe the gravitational field at every point in space. Einstein even used Riemann's research results to express his new discovery in physics in mathematical form, which is the general theory of relativity."

"By Maxwell's time, a Maxwell's equations, electricity and magnetism were unified, which made Einstein feel the pressure even later. If we look at it from the perspective of the history of human civilization, the most important events of the 19th century will be judged to be the laws of electrodynamics discovered by Maxwell, and the American Civil War of the same period will have only regional significance. ”

"As for the special theory of relativity and the general theory of relativity, not to mention, their derivation is also closely related to mathematics."

"The Yang-Mills gauge field theory, which unifies the strong, weak, and electromagnetic forces. The Yang-Mills gauge field existence and mass interval assumptions have become the seven major mathematical problems of the millennium. ”

Later, the superstring theory was born. Many physicists think that 21st century mathematics is needed to describe superstring theory, but it turns out that in the manuscript of the Indian mathematician Ramanujan, the Ramanujan modulus function proves that we can only define string theory in 26 and 10 dimensions, otherwise we cannot use string theory to integrate known physical laws. In other words, the high-dimensional universe that gave rise to our existing universe must have a dimension number of ten! ”

"All of the above examples show that in the process of studying physics, mathematical tools are the most important, and the particle collider is just an ordinary experimental device."

……

The audience has fallen into a dead silence, and even non-academic people such as Cheng Xin, Kante, and Zhang Beihai were stunned by Pang Xuelin's views.

At this time, someone said: "Without the particle collider, then how can we verify the theory, the development of modern physics has reached the deep water area, and without the top experimental equipment to demonstrate the theory, we will not be able to find the road ahead." ”

Pang Xuelin said: "We don't need to verify!" ”

"No verification required?"

"Yes, the next physics research, starting from pure theory, is based on mathematical tools, as long as a set of logical self-consistent system can be established mathematically, we can recognize the existence of this theory. We can follow the study of each set of logical self-consistent systems. In fact, hasn't the field of theoretical physics begun to do this in recent years? We don't need to verify, we only need to give the framework, as for which theory is correct and which theory is wrong, we leave it to the future and leave it to future generations to solve. ”

"So what's the point of us doing all this?"

Pang Xuelin smiled slightly and said: "As long as we can break through the blockade of Zhizi, then the existence of these theories will save our descendants countless time for theoretical research, so that they can achieve technological explosion in a very short time." Even these theories themselves may bring a way to lift the blockade of Zhizi, and it depends on whether everyone here can open their minds. ”

"Because of the blockade of Zhizi, the physics community is still in chaos. In two days I'll be in New York, where I'll propose to the Planetary Defense Council the creation of a dedicated theoretical physics research institute. This institute will bring together the world's top mathematicians and theoretical physicists to use mathematical methods to construct new physics, and all the papers and documents you produce will become the crystallization of the wisdom of our human civilization. ”

"What wanders in flux is fixed in eternal thought."

"I hope everyone here can remember that our brain, our logic system, is the most powerful tool, let us use practical actions to tell the Trisolaran, blocking a small collider, just want to block our technological development, don't even think about it!"

……

With that, Pang Xuelin got off the stage directly and walked straight out of the lecture hall, leaving only a group of stunned physicists.

Kante, Cheng Xin, and Zhang Beihai also hurriedly followed.

"Professor Pang, what you just said is so good!"

Cheng Xin exclaimed.

Although he is not interested in Pang Xuelin's character, Cheng Xin is really convinced of this guy's talent.

No wonder he was chosen as the wall-facer.

Cheng Xin thought to himself.

Pang Xuelin smiled: "I fooled them." ”

"Fooling them?"

Cheng Xin was slightly stunned, and looked up at Pang Xuelin in confusion: "But I think what you just said is very reasonable!" ”

Pang Xuelin laughed and said: "Even if we use mathematical methods to find the correct physical theory, what can we do, if we can't verify it with experiments, then there is no way to get application, and in the end it will be useless." ”

"But you ......"

Pang Xuelin said with a smile: "Of course, it doesn't mean that it is useless, the whimsical ideas of these physicists may be able to open a new door for us." Who knows, I'm just helping them point out a whole new path of research, and whether or not they will succeed in the future is none of my business. ”

Cheng Xin opened his mouth, and finally shook his head a little speechlessly.

This guy can always pour a scoop of cold water on someone's head when others are most excited.

……

Maybe it's because of Pang Xuelin's identity as a wall-facer, or maybe Pang Xuelin's words are too shocking.

In short, just one night later, Pang Xuelin's remarks have spread throughout the physics community.

The next day, many physicists had already taken the initiative to call, and in the vicinity of CERN, they directly found the hotel where Pang Xuelin lived.

Pang Xuelin specially selected several scholars with high prestige to receive them, and clearly told them that when he returned to the United Nations, he would persuade the PDC as soon as possible to integrate the world's top physicists and establish a research institute related to theoretical physics.

After staying in Switzerland for another two days, Pang Xuelin took a special plane across the Atlantic and returned to the United States.

After arriving in New York, Pang Xuelin immediately came to the office of Garning, the rotating chairman of the Planetary Defense Council.

"Professor Pang, welcome, you should come back this time for the sake of the Institute of Theoretical Physics."

Seeing Pang Xuelin come in, Garnin stood up and said with a smile.

Previously, because of the blockade of Zhizi, the physics community in various countries was in mourning, and many physicists began to switch careers to other fields.

Pang Xuelin's speech at CERN is equivalent to an essay, which points out the direction for future physics research.

PDC and even governments around the world have expressed support for Pang Xuelin's idea, and even in their opinion, Pang Xuelin doesn't need to think about convincing PDC at all, as long as he uses the authority of the wall-facing person in his hands.

But Pang Xuelin's next sentence was a little unexpected by Garning.

"Mr. President, I came over this time to persuade the PDC to establish a theoretical physics research institute just incidentally, I ask the PDC to convene a hearing on the wall plan as soon as possible, I have an important plan to announce, and the amount of resources required may be beyond your imagination."
