Chapter 821

Xu mang returned to the office of Xuyang Institute. Although everyone has been back to work for several days, Xu is back for the first time. At this time, there is a research report on quantum materials on the desk.

According to this report, the team members have successfully developed a perfect quantum gate material. Unfortunately, this technology is not mature at all and needs more verification, but it can become a reserve technology.

According to the agreement between Xu Mang and Fuda University, Xu mang judged the graduate students who came to practice and basically passed the internship. Of course, this was due to the approval of the situation. When the two groups were disbanded, Xu mang wanted to determine a new research direction and carry out expansion work at the same time.

The nuclear physics project must be put on the agenda. Although it is a huge investment to complete the nuclear physics related laboratory within three years as planned, this investment and some people paid for it. CAS, Peking University and Xiaoman jointly funded and established the Nuclear Physics Laboratory of Xuyang Institute.

The land is provided by the official Department of Mordo, and some fees are collected symbolically. In support of Xu Mang's scientific research activities, mordu has always been very generous and will not be stingy with such a small amount of money. Of course, Xu mang also knows that because his research institute is located in a remote area, if it is located in the city center, there will be more voices of opposition.

At that time, the research institute has been completed by Mr. Xu and Mr. Sun.

"Chuanxiao brother?"

"Will you come to my office?" Xu mang made a phone call to Chuanxiao, and then said, "bring the recently detected gravitational wave data together."

At the same time, Mr. Xu's hard disk arrived.

Looking at the recent gravitational wave data, Xu mang found a special gravitational wave event. He raised his head and asked brother Chuan, "why is the gravitational wave event of gw1999999 so strange? Do you think it's a suspected binary neutron star merger? "

"We suspect it's not a two neutron merger, but it's very much like a binary neutron star merger." Chuanxiao said seriously: "the mass of these two neutron stars is more than expected. The total mass of these two neutron stars is about 3.4 times that of the sun. It is half the mass of the sun than the largest known binary neutron star system."

"Ah?"

Xu mang Leng for a moment, a face confused said: "this can be other merger events?"

"I had a discussion with the group and thought it might be a more magical event." "The merger of two primary black holes, according to Stephen Hawking's theory, density fluctuations in the universe formed the oldest black hole in a short time after the big bang," Chuanxiao said

Original black hole...

Xu mang opened his mouth, but he didn't know what to say. When he studied the inflation mechanism of supermassive black hole, he didn't know who had proposed the concept of original black hole, which was rejected by himself at the beginning, but this time it appeared in the field of vision again.

Primordial black hole is also called Archean black hole, a kind of black hole only exists in theory. It is not formed by the gravitational collapse of massive stars, but comes from the ultra-high density of matter in the early big bang of the universe.

In short, it is a black hole formed by the collapse of matter directly due to the dense distribution of matter in local space in the early universe. Their formation mechanism is different from that of black holes formed by the collapse of stars.

This theory was proposed by Stephen Hawking, and later called one of the theories of understanding dark matter, because they can not be directly observed, and have a huge gravity, which meets the requirements of dark matter, but Xu mang thinks that there is no such theory. If the number of original black holes is really large enough to explain all dark matter in the universe...

in the half century after the theory was proposed, Even if they are not a small part of the original black hole, they should not exist in the original dark.

However,

can we know?

"Is there any basis?" "Can't we just throw out a theory?" Xu asked

"When we detect the gw199999 signal, we immediately search for the electromagnetic radiation signal, which is a sign of the collision of two neutron stars, but there is no signal." Chuanxiao said: "if two primary black holes merge, there will not be any light."

"Is it?"

"But no light has been detected and the possibility of neutron star merging cannot be ruled out." "The merging process of massive neutron stars may be very quiet, because they may produce black holes quickly after their collision, and they have no time to emit light," Xu said seriously

Xu mang was silent for a moment, and then said, "well... You can study it by the way, but the main energy is still on the detection of gravitational waves. We are short of manpower... The graduate students of Physics Department of Fuda have completed their internship and passed their papers in my place, and now there is no one."

"Xu mang?""You have to recruit some people." Chuanxiao said with a bitter smile: "with us, there are only seven people in total... In such a large research institute and a gravitational wave detection laboratory, the result is only seven people... Which is a bit unreasonable."

Xu sighed and said in silence, "do you think I don't want to? According to the previous agreement, the general assembly has been arranging excellent students to come to my place for practical training, so as to strengthen their research ability. If I recruit all the students, they will study a fart. "

At present, Xu mang is in a difficult position to get rid of. On the one hand, he is seriously understaffed. On the other hand, he will resume the meeting of students. If he fills up all the students, there will be no place for them.

"I'll talk about it then."

"I'm not in a hurry right now... There's a lot of things at hand." Xu mang helplessly said: "just with the help of this empty window period, some things can be solved."

Chuanxiao nodded. Then he thought of something and asked, "have you become the person in charge of the paper review group?"

"Ah?"

"How do you know that?" Xu asked in a daze.

"Recently, someone has been inquiring about this matter, and has also found me and asked me to ask you for help." Chuanxiao said: "I think it's someone else looking for him, and then he found me again, Xu mang... This is a thankless job, it's easy to be hated."

"Well."

"It doesn't matter."

"I want to see who has the power to get him through." Xu mang said with disapproval: "I'll follow the vines and search for this mysterious person, and then arrest him."

In the afternoon,

in the afternoon, Xu mang went to the computer department building and borrowed the supercomputer there to deal with the universal coverage problem. In order to solve the problem of universal coverage on 0.8441153, Xu mang designed a set of complicated program atomic scissors.

The area of 0.8441153 is small, and the area that can be trimmed is only atomic level. The process is to automatically generate 20000 graphics with the width of one in the computer program, stack them together, and then find out the method of trimming the top of the past universal covering graphics with the clue of the shape covered by them.

Simple,

rough,

and effective!

Xu mang estimated that by tomorrow morning at most, he would be able to solve the problem of reducing the total coverage area. However, at this time, he was curious about the blogger. He was a doctor in the Mathematics Department of Fuda University.

...

at 3:30 p.m.

Xu mang returned home and lay on the sofa playing games. He played a horror game "Hong Kong spy record" by means of connecting the TV series with the computer. He was attracted by Jiahui's legs. Although Xiaoman's legs were OK, her height limited her leg length.

But there is a saying, it is because of the height limit, let Xiaoman's legs and other have a different kind of fun, perhaps this is the legal strength!

If you change to a four-year period,

Xu mang may be sunk in the river... After all, he knows the law and violates the law, and his crime is more serious.

In fact,

in fact, this game is not fun. The simple jumpscale bridge without mentioning the rough modeling makes people feel infinitely disgusted. In addition, the low playability makes Xu mang feel cheated. However, considering that there are only two producers, it is difficult to judge whether the game is successful.

At least,

in terms of heat, it succeeded.

"Forget it..."

"if there is no refund, it will be considered as supporting domestic games." Xu mang quit the game and went to play another new game "tribe and machete". Its popularity was far lower than the former, but its playability was very high.

At this time,

Yang Xiaoman returned home with six or seven bags in his hand. He saw Xu mang lying on the sofa playing games without paying any attention to her. He quietly went to the kitchen and took a can of sugar free soda. Then he sat beside Xu Mang and watched him play the game.

"Wife?"

"My mouth is thirsty... Can you get me a coke?" Xu said.

Yang Xiaoman glanced at Xu Mang and said calmly: "you have become more and more lazy recently. Before that, you were very diligent. What's the situation? Is it that after I get my hands on my mother, I won't have the same motivation as before? "

In a word,

Yang Xiaoman held Xu Mang's face and asked seriously, "am I no longer attractive to you?"

Xu Mang:???

Huh?

Is this different from the frequency of Xiaoman's wave?

Always feel strange recently, she can't understand a lot of words, menopause has come in advance?

It's the same with the quarrel before,

it's clearly not about yourself and her. As a result, we quarrel at the door of the toilet in the restaurant. However, the quarrel is quite normal. There are no lovers or couples who don't quarrel in the world. If they don't express their opinions but hold them in their hearts, they will suffocate themselves.

Xu mang helplessly said: "don't make noise... Play games."Breaking away from Xiaoman's holding face, he played "tribe and machete" to himself, and then gave out a pig like laughter, which deeply stimulated Xiaoman.

We can't help feeling that Xu mang is on the way of death.

Looking at Xu Mang, he would rather play such a boring game than take a look at himself. Yang Xiaoman's anger was completely ignited like a volcanic eruption. He took a look at several shopping bags on the side and a big pig's hoof lying on the sofa.

Tonight,

it's time to take my mother back!

Wait for death!

You big pig hoof!
