From small town academic to chief scientist

Chapter 254 Some clues about dark matter (please vote)

After Zhou Yi left,

The leading abbots said to the monks below them:

"In the future, the threshold for recruiting people will be lowered. Undergraduate students only need to be mathematics students, while master's students only need science majors. Those who are not good at mathematics are not required. It is best to study mathematics."

Several monks responsible for recruiting disciples said:

"Okay, host."

Several Taoist priests looked embarrassed. Their Taoist sect did not have so many requirements.

It's just that after the Buddhist sect does this, the Taoist sect may be even weaker.

After Zhou Yi returned to his room, Peony said in Zhou Yi's ear:

"Master, the signal transmitted back by the enhanced version of Wukong, the data of low-energy electronic recoil is somewhat abnormal."

When Zhou Yi heard the news, he was shocked and said:

"Is it possible that dark matter has been found?"

"No, it could be other high-energy ray sources. Is the data transmitted to the computer?"

Zhou Yi asked a series of questions.

The enhanced version of Wukong can effectively reduce interference from other high-energy ray sources and obtain the most accurate data.

Peony said:

"The data has been transferred to the computer and is waiting for the owner to analyze it and finally draw a conclusion."

Without saying anything, Zhou Yi turned on the computer and started working.

What is dark matter? Many people don’t know.

In the vast Milky Way, in addition to stars, planets and other celestial bodies visible to our naked eyes, there may also be many invisible dark matter.

Many physicists speculate that they do not emit light and basically do not interact with other matter. They appear to be "invisible" under ordinary optical observation.

It must be said in simple academic terms that dark matter refers to a type of matter that does not participate in electromagnetic interactions.

Seeing objects through the human eye and most astronomical observations exploit electromagnetic interactions,

Dark matter cannot be detected by electromagnetic waves because it does not participate in electromagnetic interactions.

So the question is, since dark matter cannot be found, how do people guess that there is dark matter?

This is because astronomers discovered a contradiction between the mass calculated through the law of gravity and the mass detected by electromagnetic waves.

For this reason, it is assumed that there is a large amount of matter in the universe that cannot be detected by electromagnetic waves but has gravitational effects.

In 1931, Dutch astronomer Jan Oort discovered that stars in the outer reaches of the Milky Way were orbiting faster than previously estimated.

The pre-estimated orbital speed is obtained by observing electromagnetic waves and only includes the gravitational effect of visible matter.

The actual orbital speed contradicts this.

In order to explain this contradiction without changing the law of universal gravitation, it is necessary to introduce matter that does not participate in electromagnetic interaction but has a gravitational effect, that is, dark matter.

This is where the concept of dark matter comes from.

Then, in 1933, Swiss-American astronomer Fritz Zwicky used spectral redshift to measure the moving speed of each galaxy in the Coma cluster relative to the entire cluster.

And using the virial force theorem, we found that the relative motion speed of many galaxies is very high.

The centrifugal force estimated from the galaxy's velocity is much greater than the gravitational force corresponding to the visible mass of the galaxy cluster.

Therefore, it can be conjectured that there are many unobservable materials in these galaxy clusters, and their mass is large enough to produce gravitational effects that can constrain high-speed moving galaxies.

Later, many physicists came to similar conclusions,

And the enhanced version of Wukong launched by Zhou Yi is to find the results of accidental collisions of dark matter particles.

When a pair of dark matter particles accidentally collide, they may annihilate, releasing high-energy particles such as electrons, positrons, and gamma rays.

If the information of these particles can be accurately "captured", it may be possible to deduce clues to the existence of dark matter.

Now the enhanced version of Wukong has sent back a lot of data.

Zhou Yi asked Mudan to process the data according to the method initially used internationally.

It wasn't until today that Mudan discovered that there was an abnormality in the data sent back not long ago.

If you want the data, it will go smoothly.

Then a new physics may be about to begin.

A completely new type of particle will be discovered.

For several days, Zhou Yi and Mu Dan were engaged in intensive calculation work.

Five days later, Zhou Yicai numerically calculated various data through the Boltzmann equation and its total action rate.

Its remaining abundance was obtained.

Looking at this result, Zhou Yi felt a little frustrated.

"Made. Is their mathematical model wrong? This abnormal value gives me a strong hunch that it is a new type of particle.

And they are sterile neutrinos. "

Zhou Yi was cursing while replying to messages from the past few days.

During these days of retreat, two students, Zheng Keyu and Zhang Jiahui, took turns delivering meals.

Why wasn't the female student delivering the meal? Zhou Yi was afraid of causing unnecessary misunderstandings.

Moreover, Zhou Yi said a long time ago that female students are not allowed to come to him alone.

Female students must have a partner to find him, otherwise there will be some scandals.

Zhou Yi jumped into the Yellow River and was unable to wash himself away.

This method is also used by many university professors.

I don't even dare to be alone in an office with female students.

These days are the time to register for the college entrance examination, so Zhou Yi thinks it’s okay if he can’t do it for a while.

Let’s first take a look at the situation of filling in the Chongqing High Court this year.

This thing cannot be rushed. It has not been discovered for dozens or hundreds of years, and Zhou Yi does not expect to be discovered by him anytime soon.

This unscientific.

Unless the later data is more abnormal and Zhou Yi innovates a new calculation method, it will be difficult.

These calculation methods are the most accurate models obtained after repeated revisions by top physicists and mathematicians.

It's very difficult to go under the knife.

The news that Zhou Yi had come out of seclusion quickly attracted the attention of senior officials of the Yuzhou Institute of Advanced Studies and the metaphysics community.

Zhou Yi held a meeting, mainly to inquire about the application status.

It is now June 28th, and the volunteer application process has long ended.

Therefore, it is necessary to understand where future students are at in the country.

Although the scores before entering college have little reference significance after entering college,

But it can reflect a student's talent, study habits and study concentration in many aspects.

Not long after, a small meeting started.

Xu Youxiang is the executive vice president sent by the Yuzhou government and the original vice president of Yuzhou University.

Helping the Chongqing High Court deal with some matters.

A research institute similar to a university must have people who can handle things.

It is impossible for everyone to engage in scientific research.

And Xu Youxiang is also the top professor among academicians, with numerous previous academic achievements.

There are many reasons why I was not elected as an academician.

Eventually I switched from academia to administration.

At this moment Xu Youxiang said:

“Dean Zhou, directors and professors, the scores of students from our Chongqing High School this year are the highest in the entire western region.

According to our previous enrollment quota,

RTVU, Shu University, Yu University and many other colleges and universities have lower score lines than ours.

The only ones that can compare with us are the two universities in Beijing and Hua Wu.

The group of people with the highest scores are comparable to Shuimu University and Shangjing University.

And there were quite a few of them, more than thirty people in total. "

Everyone is very satisfied with this result. After all, a lot of resources were invested in marketing in the first year.

The effect is good.

Zhouyi said:

"What direction are these thirty people mainly reporting to?"

Xu Youxiang said:

"It's all math."

Zhouyi:...

Although I had some guesses, I didn't expect it to be so terrifying.

"That's not all. There are tens of thousands of people who have signed up for our school, but our graduate school requires less than 100 students.

Therefore, after admission from high to low, the rest of the people will most likely slip. "

Xu Youxiang said.

Academician Zhang on the side said:

"Actually, many of the students here are pretty good, and many of them have scored 650 points. We can expand enrollment appropriately.

The Institute of Physics, the Institute of Chemistry, the Institute of Computer and Artificial Intelligence, and the Institute of Geodynamics all need to expand their enrollment.

Our teachers are enough. "

Zhou Yi hesitated for a while and said:

"Let's recruit more people in each major, and recruit 30 people in each major."

150 people in five majors is not too small.

Hua Keyuan University only accepts 400 students every year, and it has many more driving subjects than Chongqing High School.

"With one hundred and fifty people, we can almost digest it internally. It's almost enough for each instructor to take one or two students.

If the number of tutors increases, we can continue to expand enrollment. "

Academician Zhang Tiande said.

Wang Yifang on the side said:

"We can also recruit more in physics, because we already have many scholars in physics who want to join.

Including theoretical physicists who have won many awards. In the future, the Institute of Physics will definitely become a top-notch academic institution in the world. "

Zhouyi said:

"Let's keep it this way for now. We can expand the enrollment appropriately later."

After the discussion, Zhou Yicai said:

"This admission is very successful. These students with the lowest scores can go to Shanghai Jiaotong University, Shanghai Jiao Tong University, Zhejiang University, or Aurora University. It is already very successful."

After everyone chatted for a while, Zhou Yi asked Wang Yifang to stay.

asked:

"Do you know about dark matter?"

Wang Yifang wondered:

"Why did you come to study particle physics?"

Zhouyi said:

"Isn't this about studying the nature of the universe? After solving the ABC conjecture, I want to change my taste and rest my brain."

Wang Yifang:?

To rest your brain is to change the direction of research?

Have you ever had such a rest?

Do you respect people?

Wang Yifang said:

"Of course we know that the matter that can be seen in the universe accounts for 4.9%, dark matter accounts for 26.8%, and dark energy accounts for 68.3%.

And we support WIMP very much. "

Zhou Yi smiled when he heard the result and said:

"Well, it's normal for you to support supersymmetry. Maybe string theory is right, right?

After all, the hottest candidate for WIMP-type dark matter is the lightest supersymmetric particle. "

Wang Yifang smiled awkwardly and said nothing. Zhou Yi said:

"I think sterile neutrinos are quite possible."

Wang Yifang smiled awkwardly and said:

"Professor Zhou, the XENONIT experiment seems to have some data supporting the existence of WIMP.

They detected some instances of excess with an experimental confidence level of about 3-4 sigma. "

Wang Yifang didn't expect Zhou Yi to be so unfavorable about string theory, so she could only explain it with a smile.

After all, he is the one who pays.

Zhou Yi curled his lips and said:

"It takes at least 5 σ to confirm it. It's still early. Maybe it's wrong."

Wang Yifang was still very embarrassed and said:

"We'll discuss Professor Zhou's theory later. Let's talk about CEPC."

"Um."

After Zhou Yi understood some of the situation of CEPC, he prepared to continue the retreat.

Before July 5th, Zhou Yi vowed to get it out.

Let those who do not apply for the Chongqing High Court regret it.

No one is optimistic about the Computer and Artificial Intelligence Department of Chongqing High School. It is obviously the strongest in the world, but only mathematics is seen.

This made Zhou Yi a little depressed.

As for the construction of CEPC, it is proceeding steadily, faster than Zhou Yi thought.

The construction of CEPC will also help discover dark matter.

Therefore, Zhou Yi is very concerned about CEPC.

Just when Zhou Yi was about to retreat,

Zhang Jiahui ran in and said:

"Teacher Zhou, it seems that the group of people outside have been clamoring to see you."

Zhou Yi wondered:

"Who?"

Zhang Jiahui said:

"Those people who engage in metaphysics. They are waiting for your results."

Zhouyi said:

"I don't have time, I'm busy later. Tell them to go back when they're fine, and I'll find time to write later."

Zhang Jiahui said:

"Oh, okay then."

Zhou Yi thought for a while and said:

"Forget it, let's go out and meet them in person."

After Zhou Yi saw them, he was very embarrassed when he saw them looking at him eagerly.

The leader said pitifully:

"Professor Zhou, please, you must write the rest of the article. We don't trust what others write. You are the guide of this book.

The founder of new metaphysics. "

Zhouyi:...

Zhou Yi didn't want to offend them to death. After all, it is irrational to go against a circle.

And they have a lot of basic fans. Some teenagers who believe in metaphysics do some extreme things.

It may have a bad influence, and they may even organize a group to come to the Chongqing High Court to cause trouble.

Zhouyi said:

"I'm really busy. I still have to study the data collected in recent months.

These data may shock the entire world.

How about asking my apprentice to continue writing? I will read it myself at that time and see if there are any problems. "

Everyone wanted to talk more, but when they saw that Zhou Yi looked wrong, they didn't dare to speak.

They could still tell the difference between the achievements that shocked the world and knew how Zhou Yi would choose.

The reason why Zhou Yi was so polite was that they supported Zhou Yi and criticized Ma Daoyin online.

Otherwise Zhou Yi would not be so polite.

One of the monks said very respectfully:

"Okay, we understand that Professor Zhou is busy with scientific research, but Professor Zhou should know that this book will be famous forever and be regarded as a classic by countless people.

If it had been done by someone else, Professor Zhou might not have been immortalized alone, but someone would have been alongside you. "

It must be said that these old Taoist priests and monks have a very high level of controlling people's hearts.

After Zhou Yi heard this, he said calmly:

"Am I that kind of person? I will write it within half a year. Just wait."

After talking to them, Zhou Yi left directly.

These old guys are so understanding.

It's better to go back and grab those data.

Zhou Yi felt that he had to change the mathematical model before he could make new discoveries.

Or the enhanced version of Wukong can discover more intuitive data.

The discovery of dark matter can not only complete the task, but also establish its position in the physics world in one fell swoop.

By then, we might even be able to hope for the Dirac Prize and the Nobel Prize.
