At Princeton University,

this time, he stayed in the hotel arranged by the government. As Yang Xiaoman is a non staff member, he can only stay with Xu mang. In fact, there are many rooms in the hotel, but at this time, Yang Xiaoman decided to save the money and buy milk powder for future children.

Save money?

A woman with a family in the mine said to save money... I'm afraid the earth will turn backwards.

This night,

Yang Xiaoman was not honest at all.

As the formal meeting was held the next day, after getting up, Xu mang simply washed himself, and then sat down at the table to sort out some questions, as well as some questions that others might ask. Although Xu mang understood that he would not let himself answer or let me go to the stage, he was not afraid of 10000 yuan, just in case.

There is nothing wrong with being prepared.

According to his two papers, Xu mang abstracted some main points, but did not answer the others. This is also to prevent some good people from deliberately making trouble and embarrassing themselves.

"Hello

"Why did you get up so early?" Yang Xiaoman holding the quilt, opened his eyes to see Xu Mang, with a trace of blush on his face, thinking of the matter last night, he actually... Forget it, it is the fault of this bastard.

"Prepare some materials. If I am allowed to speak on the stage, I will not be finished." Holding the pen, Xu mang wrote some content on the paper crazily.

"Yes."

"What happened to you yesterday?" Xu mang looked back, glanced at Yang Xiaoman, frowned and said, "are you crazy?"

"Go away!"

"Mom, I'm normal." Yang Xiaoman glared at Xu blankly and said unhappily, "it's not because of you, otherwise... It can't be like this."

Xu Mang: I'm sorry

last night, Xiao man was a little grumpy. Fortunately, he has a strong self-determination, otherwise something will happen.

After an hour,

Xu Mang and Yang Xiaoman went out of the room and ate a little breakfast casually. They met many big figures in the scientific research field, but they didn't know each other or even could not even name them.

At this time,

Xu mang saw a man like him, middle-aged and wearing glasses.

"How do you do?"

"Are you... Chinese?" Xu mang came to the middle-aged man and asked curiously.

"No

"Decent Chinese." The middle-aged man said with a smile.

"Ouch

"Finally see their own people..." heard the middle-aged man's answer, Xu mang suddenly left excited tears, the first time in other countries to meet their own people, the mood can be imagined.

Next,

Xu mang knew that his name was yuan Fei, a professor of astronomy at HKUST and one of the guests invited to the black hole conference.

"Are you?"

"Professor Xu, you are the same as me." Xu mang said with a smile: "invited guests of this black hole academic conference."

"Xu mang?"

"Are you Xu mang?" Professor Yuan looked at Xu Mang in surprise and then said with a smile: "I have read your paper" the conservation of information is the basic law of the universe: the mystery of lost information ", which caused a great sensation

Xu mang Leng for a moment: "Professor Yuan also saw?"

"How could you not have seen such a big thing?" Professor Yuan said with a smile: "you have solved a problem that bothers many people. Although this theory exists on paper, I think you are right through calculation."

"Oh..."

"since this paper appeared, I have been scolded by many people." Xu mang said helplessly: "I don't know who these people are, but many of them are some civil subjects. With some things I can't understand, I just refute them. Anyway, my micro blog has been Aite countless times."

Professor Yuan said: "I don't need to pay attention to him. I have met many of these people."

After that,

they chatted casually, exchanged mobile phone numbers and said goodbye.

Xu mang returned to Xiaoman and ate the bread and jam that had not been finished. It was very painful for him to live without soybean milk and fried dough sticks. Xu mang pinched his nose and ate the bread.

"Ah?"

"Who is he?" Yang Xiaoman asked.

"Professor Yuan of HKUST." Xu mang wiped his mouth: "we attended the black hole academic conference together. We just met today."

"..."

"you don't know each other, can you chat for so long?" Yang Xiaoman is speechless. This guy can talk to anyone. At first, he thought that they were old acquaintances. Who ever thought that they had nothing to do with each other.

"There's nothing wrong with a few words." Xu mang glanced at Xiaoman: "take a walk in Princeton University together?"

"Well."

...

on Princeton University campus,

Yang Xiaoman, holding Xu Mang's arm, walked in the campus with a history of two or three hundred years.

During the period,They met many foreign students.

"There are quite a lot of foreign students in this school." Xu mang sat in a chair and asked Yang Xiaoman, "will they come back?"

"..."

"I don't know." Yang Xiaoman shook his head and seriously said, "according to the conservative statistics of experts... It's about this number."

After the speech,

Yang Xiaoman made a gesture.

Xu mang looked at it and was silent. After a long time, he said, "this is someone else's own choice."

"So."

"To be strong, how to be strong... The second grandfather has given you the task." Yang Xiaoman rubbed Xu Mang's back, seriously said: "some things don't go to think, there is no significance."

"No nonsense, just emotion." Looking at Yang Xiaoman's beautiful face, Xu mang said, "I find you are more beautiful than before."

"Disgusting!"

"I've always been beautiful, OK?" Yang Xiaoman said disgusting, but his body could not help leaning against Xu Mang's arms, gently said: "have you talked about my affairs with your parents?"

Xu mang nodded: "I said two days ago, mom showed a warm welcome."

"Oh..."

"that's good."

The next day,

the long lost black hole academic conference finally arrived,

Xu Mang, as a special guest, naturally sat in the first row of the stage. Unexpectedly, the organizer arranged Professor Yuan beside him.

"Professor Yuan?"

"We are together again." Xu mang said with a smile.

Professor Yuan was also quite surprised and satisfied with Xu Mang's arrangement on his side. At least it was better to chat with someone who had a common language than to speak English with others.

"It's a coincidence." Professor Yuan said with a smile: "yesterday I went back to inquire about it. They said that you are lawless. What is the situation?"

"Ah?"

"Er..." Xu mang one time did not know how to answer this question, but said helplessly: "it may be that others misunderstood me, or they may have made a mistake."

"I think so." Professor Yuan nodded: "how can anyone who can solve this historical problem be a lawless person?"

"Yes, yes."

"Yes." "Why are there so many students?" asked Xu mang curiously

"Because it is open, it is normal for students to attend the academic exchange conference." "You will get used to it if you take part in it more times in the future," Yuan explained

At the same time,

many Princeton students, noticing Xu Mang, were immediately filled with curiosity when they saw such a young man sitting on the special guest seat.

"Who is he?"

"I don't know... Is there a mistake?"

"I think it's a mistake. The special guests are all professors in this field. Why... How did a student suddenly appear?"

"Go and talk to the security guard?"

A few good students really went to talk to the security guard at the meeting. One student deliberately sat in the guest seat, trying to sabotage.

Results...

the security guard came to Xu Mang and investigated his identity.

"By analyzing the mathematical structure of the solution, we predict a black..." Professor Yuan is explaining the history of the discovery of black holes for Xu mang. However, at this time, a young man appears, interrupting their conversation.

"Sorry to disturb you."

"Please show me your ID card." The big man asked solemnly.

Xu mang looked at the big black man with a confused face. Then he took out an invitation card from the bag. After the security guard checked it repeatedly, he handed it back to Xu mang. He didn't even say sorry and left.

"..."

"horizontal trough!"

"Is this unfair treatment?" Xu Mang's face was black and asked Professor Yuan, "where can I complain?"

Professor Yuan said with a wry smile: "it may be that you are too young to misunderstand others."

At this time, Xu was shocked by his identity as a student.

"I saw such a young professor for the first time."

"Me too."

"It is estimated that this young man is very good at being invited to the guest seat."

"Who is he

Many people are curious about Xu Mang, but they don't know who he is.

Soon,

the academic conference officially began. Xu mang saw five people sitting on the stage, but he didn't know who they were. Moreover, they didn't understand their communication, and some words were almost unheard of.

Glancing at Professor Yuan around him secretly, he found that he looked serious and felt some regret.I rely on...

I knew I would not come, and I couldn't understand what they were talking about.

Now Xu mang seems to be back in the past, listening to the English teacher talking about wordless Tianshu.

"Xu mang?"

"You... What's wrong with you?" Professor Yuan noticed that Xu mang had a dull face. Seeing that he was dozing off, he could not help but remind him: "didn't you sleep well yesterday?"

"Ah?"

"Oh..." Xu mang said helplessly, "I don't understand."

"..."

"you don't know English?" Professor Yuan asked.

"Yes."

"Level Four." Xu mang said awkwardly.

Professor Yuan was a little tongue tied for a moment. After thinking for a while, he said, "pretend to understand."

Xu mang nodded and pretended to be serious.

Unfortunately,

after a few minutes, Xu mang was no longer able to do so. However, due to the problem of face, he could not sleep. In his sober and sleepy state, he gradually went to the extreme.

All of a sudden,

the atmosphere of the meeting hall began to become a little fanatical, and everyone was clapping. Xu mang did not know what happened, so he began to applaud.

"Professor Yuan?"

"What happened?" Xu mang clapped his hands and asked curiously, "earthquake?"

Professor Yuan:

Is this...

is this really a special guest to attend the black hole academic exchange conference?

Not a tourist?

"NASA has uncovered evidence of the possibility of an initial black hole in the universe, which was 850 million years after the big bang, a big step forward from the 1.3 billion years after the big bang." Professor Yuan explained.

Then, on the big screen, Xu saw the legendary early black hole, which was actually a pixel.

Although some professional terms do not understand, but Xu mang through his understanding of black hole, probably understand what this is, this should not be a black hole, but a kind of very bright object called quasar, which is also called quasar.

However, quasars are generally considered to be AGNs. According to AGN theory, there is a supermassive black hole in the core of galaxies.

Of course,

Xu Mang's understanding of such objects is only here.

"Professor Yuan?"

"Is this supposed to be a quasar?" Xu asked curiously, "but the data show that such stars are too dark."

"I don't know."

"NASA staff are a little confused about this, they only detected three roentgen ray photons." "These three roentgen ray photons are very high in energy. If they were not for the three roentgen ray photons, they would not have found the hidden object," Yuan said

Xu Mang: (° ー)

with such a small number of roentgen ray sources, QPO can not be detected at all...

at this time,

Xu mang made an unrealistic bold thought: will the Qin ray source be covered by gas?
