Chapter 313

Xu mang doesn't know what the professor's research group is studying. Since he allows himself to guide and guide, he is not responsible for anything.

When he came to a laboratory,

Xu mang saw about ten students, both male and female.

"Cough!"

"Let's introduce it to you!" The professor coughed slightly and said to the students, "this is the top theoretical physicist in China, a professor of physics at Fuda University, and he is also a student."

What?

He's a student, a physics professor, a theoretical physicist... Who is he?

"Xu mang!"

"You should know each other?" The professor said: "the two papers on the first area of SCI are all" nature ". Recently, Xu mang has two more papers to be published in nature physics, and both papers are about black holes."

"You've made a lot of money today. If you have any questions, ask them quickly, and he will stay for half a day." The professor said with a smile, "it's better to ask him to death!"

Sleeping trough!

It's Xu Mang, Xu Da Shen!

The students present were shocked when they heard the professor's words.

Xu Mang,

the new generation of top learning gods monopolized almost all topics in Colleges and universities by their own power.

"Hello, everyone."

"My name is Xu mang... I didn't bring any gifts for the first time. I'll treat you to dinner in the evening." Xu mang said with a smile.

Treat,

is the quickest way to attract people's feelings. Xu mang has always believed in this principle.

Sure enough,

Xu Mang's position rose rapidly, almost equal to professor.

"Professor?"

"So what are you studying?" Xu mang asked curiously: "some people are simulating black hole collision, some people are calculating and don't know what ghost things."

"Well!"

"At present, we have two research directions to simulate the physical phenomena after two black holes collide. The second one is that their students think of themselves after class. When the light is close to the black hole, is there a situation that will not be sucked in?" Said the professor.

"Oh..."

"the first one I heard that you are demonstrating gravitational waves in general relativity?" Xu asked, "it is said that gravitational wave detectors have been set up in foreign countries. Does our country have any plans in this regard?"

"Yes!"

"The gravitational wave research team composed of Nantah, Qingda, Peking University, Jiaotong University, Academy of Sciences, etc., six universities and scientific research institutions, to explore the gravitational wave of general relativity." Said the professor.

Xu mang Leng for a moment, curiously asked: "we restore big?"

"..."

"you... Lack the right to speak in astrophysics, so this project does not include you." The professor said helplessly.

Is this...

so bad?

Xu mang is quite unconvinced. Why is it not included here?

"Let's go back to the University and do it ourselves!" Xu mang face discontented to say: "after the professor, we are competitors."

"..."

"is it necessary for you to..." The professor said helplessly, "if you don't have relevant equipment, how can you explore gravitational waves?"

Yeah!

No equipment.

What an embarrassment... This equipment is not cheap.

At this time, Xiao man's figure appears in Xu Mang's mind. She is holding a sign, which says "I have the ability to make money.".

"What are you laughing at?" The professor looked at Xu Mang's face and asked curiously.

"No..."

"nothing." Xu mang shrunk his head and asked, "Professor... How much does the gravitational wave detector cost?"

"Don't think about it."

"You don't have the strength and the money." The professor said seriously: "do research well, don't think about those unrealistic things."

"Oh..."

"let's get to work!"

Soon,

entering the working state, Xu mang stood behind several students and watched them simulate black holes. It seemed that the reason was that the computer technology was not enough and the action was very slow.

Alas...

too bad.

I'll deal with you later!

"Cough!"

"Who are studying light and black holes?" Xu mang coughed softly, went to a blackboard and called out: "teacher Xu has started his class. He wants to solve the problem of light and black hole. Please take paper and pen and sit down quickly!"

According to the words,

there are five or six students sitting in front of Xu mang.

"Just a few of you?" Xu took a look and began to teach the students: "your research is just the content of my paper. Although the scope of research is not about light, it almost includes the situation that light is not absorbed."Xu mang wrote down a professional word on the blackboard: inner stable state orbit.

"First of all, there is no absolute vacuum around a black hole. There will always be some gases. When these gases fall into the black hole, they will be converted into kinetic energy of the gas by gravitational potential energy, so that the gas temperature will rise."

"High temperature gas can produce light, which should be known? Something very basic. " Xu asked.

Several people nodded to show understanding.

Later,

Xu said: "not long ago, I just studied the most stable orbit in the radiation region of a black hole. There is a relatively stable and long-term orbit near the event horizon of a black hole."

Xu mang drew a relatively simple two-dimensional model.

"This is the mass stable orbit space model of the periodic oscillation signal of the roentgen ray. In the figure, we can see that the material producing the roentgen ray has the most stable orbit value in the black hole."

"Since black holes have the most stable orbits, let's go back to thinking about photons and black holes."

Xu mang was about to go on talking when he was interrupted by a curious student.

"Xu Da Shen!"

"If photons enter the innermost stable orbit of the black hole, they will be surrounded infinitely. Can we see that?" The student asked.

"It's not infinite, because the matter around the black hole will interfere with photons. Once the interference falls into the black hole or escapes from the black hole." "But we can't observe these escaping photons, and we can't do it with the current technology," Xu said solemnly

"To sum up."

"In the innermost stable orbit of a black hole, photons may be surrounded, but matter will affect photons, thus causing interference. At this time, there are two choices for photons: escaping from the black hole or entering the black hole. However, no matter the escaped photons, the falling photons and the photons remaining in the innermost stable orbit, we can not observe them."

Xu mang pauses for a moment and asks earnestly, "do you understand?"

"..."

"..."

"..."

"..."

I understand, but why do I feel sad?

Is IQ crushed?

Xu mang looked at several students and asked with a smile, "is there anything else to ask? Any question is OK. I can answer it to you. "

Listen!

Is this human language?

I'm so angry.

Although several students were very angry, their mouths were very honest. One of them raised his hand and asked, "Xu Dashen, will all matter in the universe be swallowed up by black holes?"

"..."

"classmate, this question..." Xu said helplessly: "do you know that there are one or two or even three supermassive black holes in every galaxy in the universe. Have those galaxies been swallowed up?"

"The evolution of galaxies and the growth of black holes are in harmony. In addition, if matter is to be swallowed up by black holes, the angular momentum must be minimal first." Xu mang stopped for a moment: "that is to say, you have to fall freely into the black hole."

"Unless... The whole universe stops all physical phenomena." "Of course... It's impossible," Xu said

"Next!"

As a result,

another student asked a question.

"Xu Da Shen... Can you explain why the spaceship in the movie can gain acceleration by passing through the black hole?" The student asked.

"..."

"should Hawking radiation be known?" Xu asked.

Several people present nodded.

"The general black hole, also known as Kerr Newman black hole, has a spin. This kind of black hole has an energy layer. A particle falls into the energy layer and becomes two. One particle energy becomes negative energy. The other particle energy will increase, and those with high energy will run out of the energy layer, and those with small energy will enter the energy layer."

"After all, energy is always conserved. Where does this energy come from?" "Who can answer?" Xu asked

"..."

"..."

"..."

"..."

several people shook their heads.

Xu says that the energy of the black hole is higher than that of the rotating black hole

"Do you know?"

"The energy comes from the rotational energy of the black hole!" "So why do some sci-fi movie spaceships speed up when they pass a black hole? It's extracting the rotational energy of the black hole," Xu said

"Next!"

At the same time,

at the same time,

the professor standing on the edge felt a little bad. It was not because Xu Mang's explanation was not vivid enough. The problem was that he gave a simple and understandable description of the doubts raised by the students. Although he could quickly understand the mystery, the students were all autistic.

ThisWhat should I do?

At present, the situation is completely contrary to the original intention of the professor. Originally, he planned to use Xu mang as a free labor force to let students improve their learning enthusiasm and knowledge inventory. However, the real situation is that the inventory of knowledge has increased and the learning enthusiasm has been greatly reduced.

No, no, no!

You can't ask any more questions, or these students will quit the research group.

"OK, ok... That's it." The professor quickly stopped the questioning session and said to Xu: "Xu mang... Would you like to direct the black hole collision model?"

"Your modeling skills are very strong, as can be seen from the paper." The professor said seriously, "how about... Guide them?"

"Oh..."

"that's right." "It's meaningless to stop studying light and black holes," Xu said

"Don't worry."

"It's just the students' extracurricular research. Our main goal is to explore the existence of gravitational waves." Said the professor.

Then, Xu mang stood behind a student, watching him playing with the computer.

After watching for a few minutes, Xu mang came to the back of another classmate. After watching for a few minutes, he came to the third classmate. Finally, Xu mang chose to ignore it.

Heartache!

If you're right, this collision model is based on the gravitational waves of general relativity, where it's proven.

However...

what Xu saw was a conservative, rigid and inflexible model experiment.

How to say,

although these people are great, they are not suitable for astrophysical research.

Bold assumption,

careful verification,

this is scientific research!

At this time,

Xu mang is thinking about a problem. He plans to make a big one. Based on his daily death in front of Xiaoman, he realizes the true meaning of life. Can we use this principle to let these students understand the true meaning of science?

Then...

let them really despair once. Only when they feel despair can they be reborn again!

Thinking of this,

Xu mang found the professor.

"Professor!"

"You don't have heart disease, do you?" Xu mang asked sincerely.
