I really don't want to lie down and win

What the hell!

It turned out to be Xu Mang, Great God Xu!

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

Xu Mang,

The new generation of top academic gods almost monopolize all the topics in colleges and universities by themselves.

"Hello everyone!"

"My name is Xu Mang... I didn't bring any presents when we met for the first time. I'll treat you to dinner tonight!" Xu Mang said with a smile.

dinner,

It is the fastest way to draw in the emotions between people, and Xu Mang has always believed in this principle.

as predicted,

Xu Mang's status rose rapidly, almost on an equal footing with the professor.

"professor?"

"By the way, what are you researching?" Xu Mang asked curiously, "Some people are simulating black hole collisions, and some people are calculating what the hell."

"Ok!"

"At present, we have two research directions, simulating the physical phenomenon after the collision of two black holes. The second is that their students came up with it after class. When light is close to the black hole, is there a situation that it will not be sucked in. said the professor.

"Oh..."

"I seem to have heard of the first one. Are you demonstrating the gravitational waves of general relativity?" Xu Mang asked, "I heard that gravitational wave detectors have been established abroad. Does our country have any plans for this?"

"Have!"

"The gravitational wave research team composed of six universities including Nanjing University, Tsinghua University, Peking University, Jiaotong University, Academy of Sciences, etc., plus various scientific research institutes, is exploring the gravitational waves of general relativity," said the professor.

Xu Mang was stunned for a moment, and asked curiously, "How about we re-university?"

"..."

"You... lack the right to speak in research in astrophysics, so this research project does not include your fuda." The professor said helplessly.

This...

So stupid?

Xu Mang was quite unconvinced. Why isn't Fuda counted here?

"Then let's do it ourselves!" Xu Mang said with dissatisfaction, "Professor, we will be competitors from now on."

"..."

"You kid...is it necessary?" The professor said helplessly: "You don't have the relevant equipment, how can you explore gravitational waves?"

Right!

No equipment.

How embarrassing... this equipment is not cheap.

At this time, Xiaoman's figure appeared in Xu Mang's mind. She was holding a sign saying that I have money ability.

"What are you laughing at?" The professor looked at Xu Mang with a wicked smile, and asked curiously.

"No..."

"It's nothing." Xu Mang shrank his head and asked, "Professor... how much does the gravitational wave detector cost?"

"Forget it."

"You don't have the strength and financial resources." The professor said seriously: "Do your research well and don't think about those unrealistic things."

"Oh..."

"Then get to work!"

quickly,

Xu Mang, who had entered the working state, stood behind several students and watched them simulate a black hole. It seemed that the movements were very slow because of insufficient computer technology.

Ugh...

It's too awful.

I'll clean you up later!

"Cough cough!"

"Who are studying the problem of light and black holes?" Xu Mang coughed lightly, walked to a blackboard, and shouted, "Ms. Xu has started class, and if you want to understand the problem of light and black holes, hurry up and get a pen and paper." Sit down!"

words fell,

There were five or six students sitting in front of Xu Mang.

"Just a few of you?" Xu Mang took a look and began to teach these students: "Your research happens to be the content of my thesis. Although the scope of the research is not about the problem of light, it almost includes whether light is not absorbed. Going in."

Xu Mang wrote down a professional vocabulary, internal stable orbit, on the blackboard.

"First of all, there cannot be an absolute vacuum around the black hole. There will always be some gas. After the gas falls into the black hole, the gravitational potential energy will be converted into the kinetic energy of the gas, thereby increasing the temperature of the gas."

"High-temperature gas will emit light. You should know all of this, right? It's very basic." Xu Mang asked.

Several people nodded to express their understanding.

after that,

Xu Mang added: "Not long ago, I just studied the most stable orbit in the radiation region of the black hole. Not far from the event horizon event of the black hole, there is a relatively stable and long-running orbit."

Xu Mang drew a relatively simple two-dimensional model.

"This is a mass-stable orbital space model of the periodic oscillation signal of Roentgen rays. In the figure, we can see the material that produces Roentgen rays, and the value of the stable orbital value in the innermost part of the black hole."

"Since the black hole has the innermost stable orbit, let's go back and think about the problem of photons and black holes."

Xu Mang was about to continue talking when he was interrupted by a curious student.

"Master Xu!"
