From university academician to chief academician

Space Research Institute, laboratory!

Ye Fei was sitting on a chair, surrounded by many researchers, all of whom were wearing virtual glasses.

In the metaverse!

Ye Fei stood in a square with many researchers sitting around him.

Ye Fei clicked his finger in the air in front of him, and a cosmic pattern instantly appeared in front of him.

The cosmic pattern is black with some stars in it, just like a universe that has been shrunk countless times.

"Everyone, please take a look!"

"According to the Planck test results and the ACDM model, only six parameters are needed to statistically reproduce the evolution history of the universe that is basically consistent with the observational data."

"Different observational data will have some inconsistencies when inferring cosmological parameters based on the basic ACDM model..."

"..."

"Everyone, please look here."

Ye Fei pointed his finger, and a certain part of the cosmic pattern instantly enlarged, and said: "Look, Hubble's law says that the size of the red shift is proportional to the distance, v=Hd."

"The universe has gone through an evolutionary stage with extremely high temperature and density. As the universe expanded, the energy density and temperature of the universe gradually decreased, forming the universe we see today."

"..."

"So, to study the expansion of the universe, we should establish a true redshift relationship."

The so-called red shift relationship is very complicated in professional terms. Simply put, it is an electromagnetic radiation phenomenon.

The wavelength of electromagnetic radiation increases. In the visible light band, the spectral lines of the spectrum move a certain distance toward the red end. This is the phenomenon of red shift.

Next, Ye Fei used dynamic pictures to explain to everyone the basics of cosmology and the knowledge of the accelerated expansion of the universe.

After a long time, Ye Fei finished his explanation and left the Yuan Universe.

Ye Fei took off his virtual glasses, looked at the other researchers who were taking off their virtual glasses, and said, "Everyone, we are now mainly studying the expansion of the universe. Based on what I just explained, we must find the order of black holes as soon as possible."

Everyone said: "Okay, Dean!"

At noon a month later, Ye Fei walked out of the laboratory and prepared to go to the cafeteria for dinner.

At this time, the assistant came over and said: "Dean, the meeting with Academician Li Yue is ready. When does it start?"

Ye Fei's eyes lit up when he heard this, and a trace of excitement flashed on his face.

Academician Li Yue is a fellow of the Institute of Cosmology, Xia Academy of Sciences. His research in cosmology is among the best in the world.

Let me talk about it here: Xia Guo is not good at other research fields, but in the field of space and aerospace, Xia Guo is among the top three in the world.

Ye Fei once invited Academician Li Yue and some other academicians and professors of the Academy of Cosmology, hoping to hold a small meeting in the Metaverse to ask them for some knowledge of cosmology.

It's just that these people are usually very busy, and even if there is a metaverse, it is difficult for them to get together.

Ye Fei had been dating for half a year, but it was only now that he succeeded.

Ye Fei said: "At two o'clock in the afternoon!"

The afternoon is the most sleepy time. Of course, you need to be energetic before holding a meeting like this.

Ye Fei thought that everyone should go to eat first and rest for more than an hour after eating, so that they would be more energetic during the meeting.

"Okay, Dean!"

After the assistant said this, he walked aside and took out his mobile phone to contact the other party.

Two o'clock in the afternoon, Metaverse!

There is a circular conference table with ten chairs. It is dark around the conference table, and only the area around the conference table has light.

At this time, suddenly a person appeared on each chair.

Ye Fei, Li Yue, and eight academicians or professors.

Li Yue is a middle-aged man with a slender face and thick, half-white hair.

After everyone sat down, they looked at each other and then greeted each other.

Li Yue looked at Ye Fei, who was sitting next to him, and said with a smile, "Hello, Academician Ye!"

Ye Fei smiled and said, "Hello, Academician Li!"

"Academician Ye." Li Yue said, "I heard that you want to ask us about some cosmological knowledge?"

"Yes!" Ye Feidao: "I am currently studying cosmology and looking for the order of black holes."

Li Yue said: "Where do you start your research at this stage?"

Ye Feidao: "The universe is expanding!"

Li Yue shook his head slightly and said: "This kind of research is too cumbersome. Since we are studying the order of black holes, I suggest starting with the collapse of the universe."

The universe was created from a singularity explosion. After that, the universe will continue to expand, cool, and evolve.

Scientists have discovered through research that there will be three situations in the universe, namely the open universe, the balanced universe and the closed universe.

Open universe: The universe expanded after the Big Bang. The expansion force of the expansion is far greater than the force of gravity, and the universe will expand endlessly.

This phenomenon is now generally believed by the scientific community. They believe that the universe will continue to expand.

And, the expansion speed exceeds the speed of light.

Therefore, the shrinkage and destruction of the universe will not occur in the open universe.

The universe will only continue to expand, and planets will continue to be born.

Balanced universe: The universe expanded after the Big Bang. The expansion force of the expansion is approximately equal to the gravitational force, so the expansion will become slower and slower, and finally it will expand at an extremely slow speed.

Closed universe: The universe expanded after the Big Bang. The expansion force of the expansion cannot compete with the gravity of gravity, so the inflation tends to stop when it reaches a certain level, and then collapse opposite to inflation begins. At the end of the collapse, the universe undergoes a big squeeze.

The expansion of the universe belongs to the open universe, while the collapse of the universe belongs to the closed universe. The two are opposite studies.

Then, starting from the study of the collapse of the universe, the study of the expansion of the universe will be completely invalidated.

Li Yue said: "Black holes are formed by collapsed stars. Affected by the mass of the star, different stars will undergo different change processes. Stars with sufficient mass will form black holes at the end of their life cycles."

"Therefore, it is more convenient and more direct to study black holes from the collapse of the universe."

Ye Fei's eyes lit up when he heard this, and he smiled and said: "I said that I always feel something is wrong after studying for so long. It turns out that the research is in the wrong direction."

"If I had known this, I should have asked you for advice earlier."

Although the study started from the collapse of the universe, the previous study of the expansion of the universe was invalidated.

But Ye Fei was not heartbroken at all.

He knew that it was more convenient to study the collapse of the universe than the expansion of the universe, so he must use the most convenient method.

Li Yue smiled and said: "Is there any specialization in the art industry? No one is good at any field."

"Academician Ye, you don't have to be too modest. We don't know what you know, and you don't know what we know."

Ye Feidao: "If the universe collapses, how should we study it?"

Li Yue said: "This starts with self-gravitational radiation, radiation equation of state and black hole entropy."

"Equations of states of radiation near the black hole event horizon, calculating the entropy of a self-gravitating radiation system confined in a spherical box."

"In this way, the upper limit of the total entropy of the system is exactly equal to the entropy of a black hole of the same mass formed after collapse."

"And because a black hole is a celestial body with such a curvature of space-time that even light cannot escape from its time horizon."

"So studying black hole entropy can study black hole order."

Ye Fei was very excited when he heard this, and Li Yue completely pointed out the direction of his research.

He can now feel the joy that many people had in doing research with him in the past.

It feels so good to have someone point out the direction of research.

Ye Fei smiled and said, "Academician Li, thank you so much."

"It's nothing!" Li Yue shook his head slightly and smiled: "Since you asked me specifically about the order of black holes, I naturally want to tell you."

Next, Ye Fei, Li Yue, and the other eight people present discussed the order of black holes based on the collapse of the universe.

After a long time, they ended their discussion. Ye Fei looked at everyone and said, "Thank you for helping me answer my questions today. If you have any questions in the future, you can come to me and ask."

Although everyone is a scientist in the Xia Kingdom, people get along with each other by going back and forth.

It is impossible for people on one side to give permanently without getting anything in return.

In this way, people will not be able to get along with each other for long, and they will also have a label of bad character in the minds of others.

Everyone smiled and nodded when they heard this. They helped Ye Fei, and they naturally wanted Ye Fei to help them.

As Li Yue said, Ye Fei didn't know what they knew, and they didn't know what Ye Fei knew.

Moreover, with Ye Fei's ability, there are many places where they can seek help from Ye Fei.

Ye Fei's office.

Ye Fei was sitting on the boss's chair wearing virtual glasses. At this time, he took off the virtual glasses from his eyes and put them on the table. Then he frowned in thought.

After a while, he turned on his computer and recorded the thoughts in his mind.

[Based on self-gravitational radiation, radiation equation of state and black hole entropy, the following research steps can be taken.

1. Explain the formation of black holes based on the origin of black hole entropy.

2. Modify the radiation state equation and the entropy of the self-gravitational radiation system.

3. Gravitational collapse of self-gravitational radiation system. 】

[First one: Explain the formation of black holes based on the origin of black hole entropy.

Einstein once said that for any system with an effective radius R and an energy E, the entropy of the system has a universal upper limit, which can be expressed in the Planck unit system (C=h=G=K=1) as :S≤2πER……

…

A reasonable model for the collapse of a spherically symmetric self-gravitational radiation system is that a black hole is formed first, and then the black hole gradually eats away the surrounding radiation material until the entire system collapses into a black hole. 】

After writing the first one, Ye Fei stopped, his fingers hovered over the keyboard, and he looked to the side of the computer with twinkling eyes.

Ye Feixin said: "The first one uses the origin of black hole entropy to explain the formation of black holes. I can deduce it quickly, but the second and third ones below need to be studied further."

Ye Fei raised his wrist to look at the time and murmured: "Is it already seven o'clock in the evening?"

Ye Fei put down his hand and touched his flat stomach with the other hand, "I'm really hungry."

After speaking, Ye Fei saved what he wrote and uploaded it to the core library of the quantum computer. Then he turned off the computer, stood up and walked out of the office.

The next day, in the conference room!

Ye Fei looked at the researchers sitting down. These researchers were the leaders of each group.

Ye Fei divides all researchers into many groups, each group is responsible for different work content.

Ye Feidao: "I chatted with Academician Li Yue and some cosmology academicians and professors about our research all afternoon yesterday."

"According to what Academician Li Yue said, we should study from the direction of universe collapse."

"Collapse of the universe?" As soon as Ye Fei finished speaking, the people below exclaimed.

Someone said: "But, Dean, we used to study the expansion of the universe!"

"We spent nearly half a year studying the expansion of the universe, and now we have changed it to the collapse of the universe."

"These two directions are opposite research."

"If the universe collapses instead, all our previous efforts will be in vain."

Another person said: "Yes, Dean, now we are studying the collapse of the universe. All our previous efforts have been in vain."

"Yes, yes!"

Everyone was chattering.

Ye Fei raised his hand and pressed it, signaling everyone to quiet down.

When everyone's discussion stopped, Ye Fei said: "I know that now it is changed to the collapse of the universe, and the expansion of the universe we studied before is in vain."

"However, after we study the expansion of the universe, we must also study the big bang cosmology, the space-time structure and dynamics of the universe, the energy components of the universe, cosmological distances, and the accelerated expansion of the universe."

"There are too many areas that need to be studied, and it will take half a year to successfully study it."

"And studying the collapse of the universe can be done successfully in a few months."

Everyone looked at each other hesitantly. They didn't know how Ye Fei calculated the time.

Ye Fei turned on the display screen not far away, then controlled the laptop in front of him, and displayed on the display what he wrote after the meeting yesterday.

"Everyone, please look!"

"The field of study of cosmic collapse is divided into three parts."

"The first part explains the formation of black holes based on the origin of black hole entropy."

"I've already done this part of the research."

"The rest are parts two and three."

"The second part is to modify the radiation state equation and the entropy of the self-gravitational radiation system."

"The third part is the gravitational collapse of the self-gravitational radiation system."

"These two parts of the research need your help, let us study them together."

"Once these two parts are studied, the order of black holes can be known."

"Let me talk about the discussion between Academician Li Yue and I. They pointed out the direction for our next research, so that we can do the second and third parts of the research much more easily."

Ye Fei then detailed the content of his discussion with Academician Li Yue.

After listening, everyone suddenly realized that this was the case.

According to this statement, the dean is right. It is much more convenient to use the collapse of the universe to study the arrangement of black holes than to use the expansion of the universe to study the arrangement of black holes.

Moreover, if the research direction is pointed out, the second and third parts of the research will be much easier and simpler.

Ye Fei looked at everyone who seemed to agree with his previous point of view and said: "So, using the collapse of the universe to study the order of black holes is much simpler than using the expansion of the universe."

"In my estimation, we can complete the study in three months."

"This is three months ahead of our previous forecast."

Everyone nodded and agreed with Ye Fei's statement.

Ye Feidao: "Okay, since you all agree, I will divide the work."

Ye Fei then divided the work among everyone, and each group was responsible for different work content.

After a while, Ye Fei said: "After you go back, write a research report on the research content your group is responsible for and give it to me as soon as possible."

The research report is equivalent to explaining what their future research focus is and how it should be researched.

After Ye Fei receives the research report, he will modify the research report.

They then conduct research based on research reports.

It is equivalent to saying that the research report is the outline before writing the book, and then the book is written based on the outline.

"Okay, Dean!" everyone said.

Ye Fei looked at everyone and asked, "Do you have anything else to ask?"

Afterwards, everyone asked Ye Fei some research questions, and Ye Fei answered them one by one.

After a long time, Ye Fei saw that no one asked again and said: "Okay, that's it for today, let's break up the meeting!"

After saying that, Ye Fei stood up and walked outside.
