Chapter 821 Take Back Everything My Mother Has! (One Three)

Xu Mang returned to the office of Xu Yang Research Institute. Although everyone had been back to work for several days, this was Xu Mang's first time back. At this time, there was an extra research report on the table, which was the previous report on quantum materials.

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

According to the agreement with Fuda, Xu Mang judged the graduate students who came to do the internship, and basically all passed the internship. New research directions are determined, and expansion work is to be carried out at the same time.

The nuclear physics project must be put on the agenda. It is planned to build a nuclear physics-related laboratory within three years. Although it is a huge investment, this investment has been paid for by someone. The Academy of Sciences

, Peking University, and Xiaoman jointly funded the establishment of the Nuclear Physics Laboratory of the Xu Yang Institute.

The land is officially provided by the Magic City, and some symbolic fees are charged. The Magic City has always been very generous in supporting Xu Mang's scientific research activities, and will not be stingy with such a small amount of money. Of course, Xu Mang also knows, because his research institute In remote areas, if it is located in the city center, there may be more voices of opposition.

It is gratifying,

Xiaoman's Materials Research Institute has finished the foundation, and it will be completed in another year. At that time...the two research institutes will work together, and Xu Mang has also proposed the person in charge of Xu Yang's Materials Research Institute, who is Brother Chuan Xiao His eldest nephew, Sun Yaoshui.

"Brother Chuan Xiao?"

"Would you like to come to my office?" Xu Mang called Brother Chuan Xiao, and then said, "Bring me the recently detected gravitational wave data."

soon,

Brother Chuanxiao came to Xu Mang's office, and at the same time came a data hard drive.

Looking at the recent gravitational wave data, Xu Mang discovered a special gravitational wave event, raised his head and asked Chuan Xiaoxiong, "Why is the gravitational wave event in GW199999 so strange? You judged it to be a suspected double neutron star merger?"

"We suspect that this is not a binary neutron merger, but it is very similar to a binary neutron star merger." Chuan Xiaoxiong said seriously: "The mass of this pair of neutron stars exceeds expectations, and its total mass is about 3.4 times that of the sun. The largest known binary neutron star system weighs half the mass of the sun."

"ah?"

Xu Mang froze for a moment, then said with a confused face, "Could this be another merger event?"

"I discussed it with the team members, and I think it may be a more magical event." Brother Chuan Xiao said: "According to the theory proposed by Stephen Hawking, the merger of two primordial black holes occurred shortly after the big bang." Density fluctuations in the universe formed the oldest black holes of this kind in a period of time."

primordial black hole...

Xu Mang opened his mouth, but he didn't know what to say. When he was doing research on the inflation mechanism of super-large black holes, he didn't know who proposed the concept of primordial black holes, but he rejected it at the beginning. However, this time it appeared again in view.

Primordial black holes, also known as primordial black holes, are a kind of black holes that only exist in theory. They are not formed by the gravitational collapse of massive stars, but are derived from the ultra-high density of matter during the Big Bang inflation in the early universe.

To put it simply, it is a black hole formed by the direct collapse of matter due to the dense distribution of matter in the local space in the early days of the universe. Their formation mechanism is different from the usual black holes formed by the collapse of stars.

The theory here was proposed by Stephen Hawking, and it was later called one of the theories to explain dark matter, because they cannot be directly observed, and at the same time have a huge gravitational force, which meets the requirements for dark matter, but Xu Mang feels that it does not exist. If the original black hole The amount is really large enough to explain all the dark matter in the universe...

Half a century after the theory was proposed, the search for primordial black holes should not be fruitless. Even if primordial black holes did exist, they would only constitute a small fraction of dark matter.

but,

How can I know this?

"Is there any basis?" Xu Mang asked, "You can't just throw out a theory, right?"

"When we detected the GW199999 signal, we immediately searched for electromagnetic radiation signals. This is a sign of a double neutron star collision event, but there is no signal." Brother Chuan Xiao said: "If two original black holes merged If so, there will indeed not be any light.”

"Yeah?"

"However, the possibility of neutron star mergers cannot be ruled out even if no light is detected." Xu Mang said seriously: "The merger process of massive neutron stars may be very calm, because black holes may be formed quickly after they collide, and there is no time to release them." light."

Xu Mang was silent for a while, and then said: "How about this... You can study it by the way, but the main focus is on detecting gravitational waves. We don't have enough manpower... The graduate students from Fuda's Department of Physics have completed their internships , also passed the thesis in my place, and now there is no one."

"Xu Mang?"

"Speaking of which, you need to recruit some people." Brother Chuan Xiao said with a wry smile: "Including the few of us, there are seven people in total... such a large research institute plus a gravitational wave detection laboratory, the result is seven people... .It's kind of outrageous."

Xu Mang sighed, and said silently: "Do you think I don't want to? According to the previous agreement, the conference has been arranging outstanding students to my place for training to strengthen research capabilities. If I recruit all the people, they will still study Shit."

Now Xu Mang was riding a tiger. While he was seriously short of manpower, he was recruiting students from the General Assembly. If they were fully recruited, there would be no places for these students.

"Let's talk about it later."

"I'm not in a hurry right now... There are a lot of things on hand." Xu Mang said helplessly, "It's just a matter of taking advantage of this empty window to settle some things."

Brother Chuan Xiao nodded, then he thought of something and asked, "Have you become the person in charge of the thesis review team?"

"ah?"

"How do you know?" Xu Mang asked in surprise.

"Someone was inquiring about this recently, and they found me, asking me to plead with you." Brother Chuan Xiao said, "I think someone else came to him, and then he found me, Xu Mang... this It's a thankless job, and it's easy to be hated."

"Um."

"It doesn't matter."

"I want to see who has the power to let me pass him." Xu Mang said disapprovingly, "I'll follow the clues to find this mysterious person, and then arrest him."

afternoon,

Xu Mang went to the computer department building, borrowed the supercomputer there, and solved the problem of universal coverage. In order to solve the problem of 0.8441153 and continue to reduce this value, Xu Mang designed a complex program for this - atomic scissors .

In the small area of ​​0.8441153, the area that can be trimmed is only at the atomic level, and the process is to automatically generate 20,000 graphics with a width of one in the computer program, stack them together, and then use the shape covered by it As the clue, it is finding out the repairing method of the top of the past universal covering graph.

Simple,

rough,

And it works!

Xu Mang roughly estimated that by tomorrow morning at most, the problem of shrinking the universal coverage area could be solved, but at this time he was curious about the blogger, who was a Ph.D. student in the Mathematics Department of Fuda University.

...

half past three in the afternoon,

Xu Mang returned home, laying on the sofa and playing games. Using the TV series to connect to the computer, he played a horror game "Hong Kong Strange Records". He was attracted by Jiahui's legs in it, although Xiaoman's legs It's also quite OK, but it's a pity that her height limits her leg length.

But there is one thing to say, it is precisely because of the height restriction that Xiaoman's legs and others have a different kind of humor, maybe this is the legal power!

If it is changed to four years,

Xu Mang might be drowned... After all, if you know the law and break the law, the crime is aggravated.

actually,

This game is not fun, not to mention the rough modeling, but the simple Jump scare section, which makes people feel infinitely disgusted, and the playability is too low, Xu Mang felt that he was cheated, but thinking about making With just two people on the side, it's hard to tell if the game is a success.

at least,

In heat it worked.

"never mind..."

"If you don't get a refund, consider supporting domestic games." Xu Mang withdrew from the game to play another new game, "Tribe and the Machete".

At this time,

Yang Xiaoman returned home with six or seven bags, saw Xu Mang lying on the sofa playing games, and ignored her, went to the kitchen silently to get a can of diet soda, then sat beside Xu Mang, Watch him play games.

"Wife?"

"My mouth is thirsty... Can you get me a can of Coke?" Xu Mang said.

Yang Xiaoman glanced at Xu Mang, and said calmly, "I mean, you've become more and more lazy recently, but you were quite diligent before, what's the matter? Did you lose the motivation you used to have after getting my old lady into my hands? "

words fall,

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

Xu Mang:? ? ?

ha?

Is this different from Xiaoman's radio frequency?

I always feel weird recently. She can't understand many words. Menopause has come early?

I quarreled before, too.

It was obviously not about me and her, but I ended up quarreling at the toilet door of the restaurant, but quarreling is quite normal. There are no couples or couples in this world who don’t quarrel. Opinions will always be different. If you don’t express your opinions, But if you hold it in your heart, you will suffocate yourself.

Xu Mang said helplessly, "Don't make trouble...just play a game."

Breaking away from Xiaoman's face-to-face killing, he played "The Tribe and the Machete" by himself, and then let out a pig-like laugh, which deeply stimulated Xiaoman.

I have to sigh,

Xu Mang was walking on the road of death.

Seeing that Xu Mang would rather play this extremely boring game than look at himself, the anger in Yang Xiaoman's heart was completely ignited like a volcanic eruption... Glancing at the few shopping bags beside him, He glanced at the big pig's trotter lying on the sofa.

tonight,

It's time to take back everything I have!

wait to die!

You big pig's trotter!
