Xu Mang glanced at the caller, and it was Brother Chuan Xiao who called.

What's going on

You are still calling so late. Is there something urgent?

"Who is he?"

"You didn't even check what time it was and you still called." Yang Xiaoman was very dissatisfied with this and said angrily: "You still interrupted my conversation."

"He's an observatory researcher in Shanghai and a black hole physics researcher." Xu Mang said, "Brother Chuan Xiao is elegant, easy-going and a very nice person. You should know that he is the online love expert."

"Oh" Yang Xiaoman nodded: "Take it."

Immediately,

Xu Mang answered the phone.

"Hello!"

"Xu Mang!" Brother Chuan Xiao said seriously: "I compared the tidal tearing of the 14li star with some past data, and I found that there is a problem in the data."

"question?"

"What do you mean?" Xu Mang asked with a confused look on his face.

"When a black hole engulfs a star, it emits not only Roentgen rays, but also ultraviolet rays, infrared rays, and radio waves." Chuan Xiao said, "The most important ones are Roentgen rays. There seems to be a problem with these Roentgen rays."

Xu Mang was stunned for a moment. He didn't react for a while and asked with a confused face: "I don't understand at the moment."

"I will now send you the data I collected. This is the data of black hole Roentgen rays observed by scientists around the world." Brother Chuanxiao said: "I made some deletions and left some useful ones. You can do the calculations.

"

"oh"

hang up,

Xu Mang looked at Xiao Man in his arms and saw her staring at him with curiosity on her face. He couldn't help but smile and said, "He discovered something incredible and then asked me to do the calculations."

"Now?"

"No, tomorrow."

"oh"

Xiaoman leaned into Xu Mang's arms and said silently: "Just hold me and sleep like this."

Xu Mang: Embarrassed

Want to die

This woman can really figure it out.

Then the two slept on the sofa all night

The next day,

Yang's mother returned home. In fact, Yang Jian was not seriously ill and could be discharged from the hospital today. However, in order to attend classes for his daughter, Yang Jian decided to stay in the hospital for a week to tell Xiaoman that she should order takeout in the future.

No more chemicals.

pity

Yang Jian was wrong.

Because his nightmare has just begun.

""

As soon as Yang's mother took off her shoes, she saw two people on the sofa in the living room, hugging each other tightly. Without guessing, she knew they were her daughter and future son-in-law.

well

Young man.

Mother Yang thought about the time when she and Yang Jian were in love. She accidentally touched his hand while shopping and her face turned red for half an hour. It was like now. Times are progressing. Young people should have young people.

thoughts.

Anyway, Xiao Xu was his appointed son-in-law. He got on this pirate ship without a life jacket or lifebuoy. There was no reason to go back. There was only one choice before him, to stay on this pirate ship forever.

"Ahem!"

No response.

"Ahem!"

Still no response.

Mother Yang silently put on her shoes again, and then went to the company.

This young couple,

How late did you get crazy last night?

for a long time,

Half past eleven noon.

The two of them just got up on the sofa. In fact, Xu Mang woke up as early as half past nine, but he didn't dare to move.

"What to eat?" Xiaoman asked, "How about I make you a bowl of braised pork and fried rice?"

"No, no, no!"

"I"

"I haven't digested what I ate yesterday." Xu Mang said quickly, "Hey Brother Chuanxiao seems to have sent me some information. I need to go back right away."

"snort!"

"Not approved!" Yang Xiaoman rejected Xu Mang's idea of ​​going back on the spot, and said calmly: "Go back tomorrow afternoon. I have a computer in my room. You can use my computer to work. In short, you don't have to go anywhere today.

Want to go!”

have no choice,

Under Xiaoman's dominance, Xu Mang chose to surrender temporarily.

When he came to Xiaoman's room and turned on her computer, Xu Mang received information from the elegant and easy-going Chuanxiao brother.

This information contains the most information about the black hole numbered 14li. This is a very famous black hole. It tells the world that the tidal force of a black hole can disintegrate other celestial bodies, commonly known as black hole swallowing.

What is it?

How to calculate?

Give me an explanation!

Xu Mang looked at the data with a blank look on his face, not understanding what he was going to do now.

Let me pay attention to the Roentgen rays and what do they do?

Roentgen rays are also known as x-rays, an electromagnetic wave with extremely short wavelength and high energy, but what's the point? This is something in the field of nuclear physics.

But it is different in astrophysics. Roentgen rays come from accumulation.

after,

Based on the data given by Brother Chuanxiao, Xu Mang built a 14li model to simulate the scene of a black hole swallowing a star at that time. It was boring anyway, so he just watched cartoons.

certainly,

This work is relatively time-consuming.

According to estimates,

It will take at least a day and a night.

Don't say it yet

Just before I leave here, I can complete this model.

When building this animation model, Xu Mang had to marvel at Brother Chuan Xiao's awesomeness. He could actually find such detailed information. He was probably making a crawler software to crazily copy other people's information on the Internet.

but

I'm not the same kind of person. I've crawled all over the world's public and non-public data.

"Crazy waves are an attitude, wild waves are rising and falling, wild waves, crazy"

"well?"

"Is this a coincidence?" During the modeling process, Xu Mang accidentally discovered that Roentgen rays seemed to have a significant periodic light change.

What is going on?

Is it an error in the observation data?

Xu Mang did not give up and looked for data records from other observation equipment in the information provided by Brother Chuan Xiao. The results showed that the three sets of data showed that the Röntgen rays released had periodic light changes.

Xu Mang:

Is this qpo? Quasi-periodic oscillation
