From all-round academic master to chief scientist

"First of all, welcome everyone here to our first meeting."

"It has taken more than ten years since CEPC-SppC was first proposed and successfully constructed. Such a feat is not only an event worth celebrating in our scientific community, but also It is also an event worth celebrating for all mankind.”

"Because this not only means that our human technological level has been further developed, but also means that we are one step closer to discovering new science."

"As the chairman of the academic committee, and as a person born and living in this country, I feel very proud of this."

"Of course, I won't say more about other specific things. I believe in these specific things, such as how powerful our collider is and what kind of status it has in our scientific community. I think I don’t need to say more.”

"Then, what I want to say next is about the future scientific research plan arrangements."

"The first phase of the plan will start in two weeks."

"This plan is not only a trial run to test the stability of our CEPC-SccP, but also to conduct research on multiple scientific issues such as gravitons, Higgs bosons, neutrinos, and micro black holes while ensuring stability. discussion.”

"The collision energy of 118TeV will reveal to us more wonderful scenes and real ideas in the microscopic realm! And I believe that both I and any of my friends here have been looking forward to this for a long time."

"Then, I won't say more about other things. Please let me wish here that the first operation plan will be a complete success. At the same time, I also wish that our science can be successful after this first operation. , blossom into more wonderful results.”

"Thanks."

At the end of Lin Xiao's speech, the audience also gave him applause. Obviously, compared to the previous speeches, Lin Xiao's description of their future scientific research plan for the collider was the most interesting to these scientists. After all, , which means whether they can have room to play in this plan.

Obviously, fortunately, the scientific plan Lin Xiao said was basically the same as what they thought.

The discovery of gravitons has obviously been the most concerning thing in the high-energy physics community during this period. After all, it concerns one of the most basic concepts in physics, namely the gravitational interaction force, one of the four fundamental forces.

If the electromagnetic interaction force, the strong interaction force and the weak interaction force constitute various manifestations in the microcosm, then gravity forms the basis of the entire universe phenomenon.

Gravity allows celestial bodies to show magnificent spectacles, allows planets to condense, and the orbit between planets and stars, and also allows weird and wonderful celestial bodies such as neutron stars and black holes to appear.

So every physicist can't wait for this.

This is true even for Lin Xiao. After all, he was the one who told the physics community that gravitons definitely existed.

In addition to gravitons, other projects have also been hot research topics in the scientific community, such as further observations of the Higgs boson and neutrinos.

As for the subject of micro black holes, it was also because Lin Xiao discovered its existence after in-depth processing of experimental data using the "mathematical vaccine" root search method at CERN. Therefore, in this experiment, these physicists They also really want to further discover its existence.

Studying micro black holes will help them further understand the secrets of gravity. Naturally, the secrets of gravity cannot be fully revealed only by the discovery of one graviton.

Just like whether the interior of a black hole is in a higher dimension or has another world, it is still an unsolved mystery. It is not impossible that there is anything in a black hole, but what it is, for scientists , is an unsolved mystery.

So, with the joint expectations of thousands of high-energy physicists who have come to the scene and tens of thousands of scholars around the world, the time has gradually come to the two days before CEPC-SccP is about to run.

…

The underground tunnel where the CEPC-SccP proton collision detector is located.

Lin Xiao was walking here, and there were many people around him, including Wang Yi.

"How is it? Is our underground world shocking enough?"

Wang Yi saw Lin Xiao stopping and looking at the detector, and said with a smile.

Probably because the knot in their hearts has been resolved, Wang Yi and Lin Xiao have become more and more familiar with each other during this time.

This time, Lin Xiao said that he would go underground to see this 70-kilometer-long collider in person before its first operation. Although he didn’t know why Lin Xiao suddenly became so interested, Wang Yi still found the time. He followed Lin Xiao here and introduced this thing to Lin Xiao like a treasure trove along the way.

"It's really shocking."

Lin Xiao nodded and said with a smile.

The space of the detector is different from the main body of the pipeline. Because the detector is where the collision occurs, a large number of sensors and processors are needed to process the data, so its volume is also very large.

It's like a building built underground.

Wang Yi smiled and said: "Of course, you are indeed much smarter than me. I am not as good as you in scientific research, but I think I am quite knowledgeable about the construction of such a huge project, although the one you are responsible for is controllable. The nuclear fusion device is also a big project, but it is still not as big as my project."

Hearing Wang Yi talk and feel complacent, Lin Xiao didn't pay attention and said casually: "Yes, yes, he is indeed older than me."

As he spoke, he looked up again, as if he was looking for something.

Wang Yi also heard the perfunctoriness in Lin Xiao's words. Just as he was about to say a few more words, he suddenly saw Lin Xiao walking towards the detector.

I saw Lin Xiao walking up to a staff member who was undergoing final inspection and asked: "Hi, may I ask, is it possible to go inside this detector? I want to take a look at the internal pipes."

The staff member turned his head and was immediately surprised when he saw that it was Lin Xiao talking to him: "Lin Shen?"

Then he realized that Lin Xiao was asking his own question, and then quickly replied: "Okay, okay, you need to go to the top of the detector first, and then there is a maintenance channel there. After entering the channel, you can enter the interior. Pipeline."

At this time, Wang Yi also walked up and asked doubtfully: "Academician Lin, what's wrong with you?"

Lin Xiao smiled and patted the employee in front of him on the shoulder and said, "Thank you."

Then he smiled at Wang Yi and said: "Our channel is operating for the first time, and I want to leave something to commemorate."

"Something to commemorate?"

Wang Yi became confused.

At this time, Lin Xiao also took out the truth recording pen from his arms.

He laughed: "I want to record the sound of the collision."

Wang Yi was even more confused now.

"The sound is a collision? But this is a particle collision. Where does the sound come from? It doesn't vibrate and make sound."

"Electromagnetic waves."

Lin Xiao spread his hands, "Just like the sounds belonging to the universe recorded by those who study astronomy, this recording pen of mine can also record electromagnetic waves."

Wang Yi was stunned for a moment, then couldn't help but laugh, "So that's it, I thought you were going to record the sound of the collision."

"However, if the sound of electromagnetic waves is recorded, there should be a lot of noise, right?"

Lin Xiao smiled, "Let the noise be noise. I don't expect to be able to record anything. Even if it's just a commemoration, that's what I said just now."

Wang Yi nodded, "Okay, since you are interested, then go ahead, but the maintenance channel inside seems a bit small. How about asking the staff here for help?"

Lin Xiao waved his hand, "No need, I'll just come in person."

"Fine."

Wang Yi nodded and asked no more questions.

Lin Xiao first climbed up the ladder to the top of the detector, and then, under the guidance of other staff, came to the maintenance channel.

Through this very narrow maintenance channel, Lin Xiao finally reached the bottom.

Seeing the pipe inside, a smile appeared on his face.

Finally, I got here smoothly.

The months of waiting have finally come to an end.

He took out the truth recorder again and pressed the depression on it.

And the system's voice also sounded: "The recorder starts up and starts working. It can be turned off at any time, and at the end, a fragment of it is intercepted and translated by the system."

Lin Xiao's face showed a satisfied expression.

Yes, in this case, you only need to wait until the collision is over, then come over and take away the recording pen.

This recorder seems to have infinite energy and can record forever.

Of course, he could only intercept at most two fragments for translation.

Without thinking any more, he fixed the recorder on the pipe and left.

He is not worried about this recorder being discovered by others, because to others, this recorder can only be a recorder, not a truth recorder.

Then he stopped paying attention, left the place, returned outside, and continued to tour with Wang Yi inside.

…

Two days passed quickly, and the day of official operation arrived.

In the ground monitoring laboratory, multiple working groups composed of thousands of people began to make preparations.

In the central control room, Lin Xiao, Wang Yi and other core figures of China's high energy physics research organization are all here.

"All departments and working groups have been prepared, and the equipment and instruments have undergone final calibration. All equipment can operate normally and can now be officially started."

A staff member told Wang Yi the news.

Wang Yi also showed excitement, and then said: "Then, no need to say more, now let's start our collider!"

"yes!"

The staff responded immediately and then conveyed the instructions given by Wang Yi to all departments.

Then, in the underground tunnel where everyone had evacuated, huge energy began to be transmitted out, and at the same time, huge electrical energy was also input into it.

The collision energy of 118 TeV requires a huge amount of power.

Of course, because they have prepared enough superconducting energy storage coils in advance, they basically don’t have to worry about insufficient power supply.

In this way, an extremely large current circulates in the internal superconducting coil, accompanied by a magnetic field force of up to 18T.

The equipment serving as the "munitions bay" also put an extremely large number of particles into it.

The collision has begun!

Under the influence of the strong magnetic field force, the charged particles were pushed up and began to rotate rapidly around the pipe. In this way, their speed was accelerated from 0 to a level not far different from the speed of light. Then, Collisions occurred at the locations of each collider.

The number of collisions per second is as high as hundreds of millions. Of course, due to the limitations of sensor and data processing technology, very little data can be retained.

But even so, you need to know that the data generated by a single collision is several MB in size, which means that even if there is very little data retained in the end, the amount of data generated every second is tens of terabytes in size. .

Therefore, in the process of building CEPC-SppC, the construction of the database is also a costly project.

Of course, cutting-edge science means burning money.

So for these scientists, as long as they are not using their own funds, money is really just a number.

…

In this way, as time passed and after the collision began, various departments and working groups also obtained the processed data of the collision.

These data are very huge, but after all, this is an era of computers. Through computers, they can obtain various processing results more easily.

In this way, as each data was processed, the operation of the collider ended when all the spare superconducting energy storage coils were almost used up.

The whole thing takes about three hours.

The data generated in three hours was enough for them to study for a while.

"Okay, it's over."

In the central control room, Wang Yi looked at the message on the monitor that all power supplies had been disconnected and the collider had entered a shutdown state. Then he sat back in his seat and let out a sigh of relief.

For him, he can be called the most stressed person. After all, as the main person in charge, if something goes wrong during the operation, it will not only mean that his hard work over the past ten years has been undone, but it also means that he needs to be responsible for the failure. responsible.

Fortunately, however, the results were good.

The people next to him smiled and sent blessings to him, and Lin Xiao did the same.

Of course, compared to their joy, Lin Xiao was more concerned about the condition of his recorder at this time.

Thinking about it, the most intense collision should have been recorded, right?

His eyes moved slightly, and he couldn't wait any longer.

Of course, since there is radiation in the collider now, it is not possible to enter it in the short term. You need to wait for a period of time before the radiation level drops enough to allow you to wear safety clothing, and this period of time will be at least a month.

So no matter how anxious he was, no one would allow him to go down, let alone just pick up a voice recorder.

Even if it is not a voice recorder, but a very important thing, today's China will not allow its scientists to go into radiation to obtain experimental data.

Ever since, Lin Xiao had nothing to do, so he joined the research team and began to process the experimental data.

The data generated by the collision energy of 118TeV is very "exciting", that is to say, the data has become more messy, at least more messy than the data generated by the LHC next door in Europe.

Of course, this kind of chaos is a very good signal to scientists, because it means that there may be some new physics and new particles in it, and they only need to process these messy data through mathematical methods. That's it.

However, when it comes to actually starting to process this data, most people feel embarrassed.

Because this data is too difficult to process.

Even though they have used the "mathematical vaccine" proposed by Lin Xiao to process this data, the final complexity of the data still makes them difficult to handle.

However, only the vast majority of people think so, which means there are still people who don’t think so.

This is naturally Lin Xiao.

As the proposer of the "mathematical vaccine", his status in chaos system research has been directly elevated to the top level. Therefore, when faced with these data, even he found it a bit tricky at first, but it didn't take long for him to completely understand it. Familiar.

Therefore, within a month, he completed two papers one after another and uploaded them to their website.

These two papers are about the determination of gravitons and micro black holes respectively.

In his two papers, he proved the clear existence of gravitons, and once again found out the existence of miniature black holes from the huge data.

Once these two papers were uploaded, they spread wildly among their research organizations. Similarly, the outside world also got the news.

As a result, this time not only the high-energy physics community, but the entire physics community was shocked by this news.

Although Lin Xiao has proved the existence of gravitons in papers before, as some physicists, especially relativistic physicists insist, they still refuse to admit the existence of gravitons if it is not discovered through experiments. .

Now, in Lin Xiao's paper, the existence of gravitons is already irrefutable. Even if you want to deny it, this is an unchangeable fact.

It is impossible to observe directly through a microscope.

Today's microscopes can't even detect atomic nuclei, so how can we talk about gravitons?

Therefore, not long after Lin Xiao's paper was uploaded, the China High Energy Physics Research Organization officially held a press conference to officially announce the news.

Even the government is very concerned about this matter.

"In short, according to Professor Lin Xiao's paper, we can now basically confirm that at the huge collision energy of CEPC-SppC, gravitons will be produced as predicted, and according to calculations, the error margin is only within ±0.15% , completely in line with our expected error!”

At the press conference, following Wang Yi's announcement, the reporters present took photos, while the invited scientists applauded to celebrate such a major event.

"Next, let's invite Professor Lin Xiao to give a speech."

Then, Wang Yi turned to look at Lin Xiao next to him with a smile.

This time, he was very grateful to Lin Xiao.

This paper clearly demonstrates the importance of their CEPC and its role in promoting world science.

I believe that under the influence of this paper, they will be able to attract more first-class physicists here, thereby further enhancing their country's scientific influence.

This was also guaranteed by his superiors when he applied for this project, and at least for now, this goal has been achieved.

At this time, Lin Xiao also smiled slightly, then stood up, picked up the microphone, and expressed his thoughts: "As for the existence of graviton, after my original paper was published, I have no doubt about it. Yes, and now, it has indeed confirmed my suspicion.”

"At this moment, I just want to say to everyone that we have once again taken an important step towards the truth!"

"..."

This press conference is also live broadcast on their official website.

There are many people watching this live broadcast, and of course, these people are also people in the physics world.

"How's it going? Maldacena, are you willing to admit the existence of gravitons now?"

In the Institute for Advanced Study in Princeton, Witten said to Maldacena with a smile.

He had not forgotten that Maldacena had always refused to admit it.

Maldacena curled her lips, "Just admit it, what's the big deal."

Witten laughed.

It’s really interesting to see this old friend reluctantly, but having to admit defeat when faced with the “truth”.

Of course, this is also the power of truth.

Watching Lin Xiao in the live broadcast, Witten sighed slightly in his heart. This young man has once again proved himself.

…

The press conference ended quickly.

Just as Lin Xiao was about to leave, he suddenly received the news.

"Your recorder has been taken out and now it has been placed in the research institute."

After hearing the news, Lin Xiao suddenly became excited, and then headed to the research institute without stopping.

More than a month has passed now, and the radiation value inside the collider has dropped to a safe value, so they also sent maintenance personnel to go inside for repairs, and also helped Lin Xiao get his recording pen. .

Lin Xiao, who had been impatient for the voice recorder, naturally didn't want to wait for a moment.

When he arrived at the research institute, Lin Xiao found the staff member who helped him get the recording pen.

"Academician Lin, your pen."

I took the pen that was handed to me. In fact, the pen was packed in a radiation-proof box, probably to prevent radiation from being carried underneath.

Lin Xiao smiled and said: "Thank you."

"You're welcome." The staff member responded, but then asked curiously: "By the way, Academician Lin, what kind of material is your recording pen made of? After I took it out, I didn't detect it from above. Radiation value.”

Lin Xiao was stunned for a moment, then shook his head and said: "Can't the radiation value be detected? I don't know that, but thank you anyway."

This staff member didn't pay too much attention to it. Compared with Lin Shen's thanks, these are not worth mentioning.

He waved his hands repeatedly and said, "I've said it all. You're welcome. Academician Lin, please go ahead and do your work first. I have other things to do, so I'll leave first."

"OK."

Lin Xiao nodded, and then left here no longer.

He wanted to see what truth was recorded in this pen!

Two chapters combined into one
