Xu Mang returned to the office of the Xu Yang Research Institute, although everyone had been back to work for several days, but it was the first time that Xu Mang had come back, and at this time there was an additional research report on the table, which was the previous report on quantum materials.

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

According to the agreement between Xu Mang and Fuda University, Xu Mang gave the graduate students who came for internship to judge, and basically passed the internship, of course, this was due to the situation, when the two groups were disbanded, Xu Mang had to determine the new research direction, and at the same time to carry out the expansion work.

The nuclear physics project must be put on the agenda, and the nuclear physics related laboratories will be built within three years in the plan, although it is a huge investment, but this investment and someone has paid for it, the Academy of Sciences

, Peking University and Xiaoman jointly funded the establishment of the Nuclear Physics Laboratory of Xuyang Research Institute.

The land is officially provided by the magic capital, and some fees are charged symbolically, in support of Xu Mang's scientific research activities, the magic capital has always been very generous, and will not be stingy with such a little money, of course, Xu Mang also knows, because his research institute is in a remote area, if it is located in the center of the city, I am afraid that there will be more objections.

It is gratifying,

Xiao Man's materials research institute has completed the foundation, and it will be completed in another year, when ... The two research institutes worked together, and Xu Mang also proposed the person in charge of the Xu Yang Materials Research Institute, who was Sun Yao Shui, the eldest nephew of Brother Chuan Xiao.

"Brother Chuanxiao?"

"Would you like to come to my office?" Xu Mang made a call to Brother Chuan Xiao, and then said, "Bring the recently detected gravitational wave data with you." ”

soon

Brother Chuan Xiao came to Xu Mang's office and arrived at the same time a data hard disk.

Looking at the recent gravitational wave data, Xu Mang discovered a special gravitational wave event, raised his head and asked Brother Chong Chuanxiao, "Why is the gravitational wave event of the GW199999 so strange?

"We suspect it's not a binary neutron merger, but it's a lot like a twin neutron star merger. Brother Chuan Xiao said seriously: "The mass of this pair of neutron stars exceeds expectations, its total mass is about 3.4 times that of the Sun, and it is half a solar mass heavier than the largest known binary neutron star system." ”

"Huh?"

Xu Mang was stunned for a moment, and said with a confused expression: "Could this be another merger event?"

"I discussed it with the group and thought it could be a more magical event. "The merger of two primordial black holes, according to the theory proposed by Stephen Hawking, formed the oldest black hole of this kind by fluctuations in density in the universe in a short period of time after the Big Bang. ”

Primordial black holes...

Xu Mang opened his mouth, but he didn't know what to say, when he was doing research on the mechanism of super-large black hole inflation, he didn't know who proposed the concept of primordial black holes, and he was vetoed by himself, but this time it appeared in the field of vision again.

A primordial black hole, also known as a primordial black hole, is a type of black hole that exists only theoretically, not formed by the gravitational collapse of massive stars, but from the ultra-high density of matter during the Big Bang explosion in the early days of the universe.

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

The theory here was proposed by Stephen Hawking, and later it was called one of the theories to explain dark matter, because they cannot be directly observed, and at the same time have a huge gravitational pull, which meets the requirements for dark matter, but Xu Mang feels that it does not exist, if the number of primordial black holes 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 nothing, and even if primordial black holes did exist, they would only constitute a small fraction of dark matter.

But

How can this be known?

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

"When we detected GW199999 signals, we immediately searched for electromagnetic radiation signals, which are signs of a binary neutron star collision event, but there were no signals. Brother Chuan Xiao said: "If the two primordial black holes merged, there would indeed be no light. ”

"Really?"

"But the absence of light does not rule out the possibility of a neutron star merger. Xu Mang said seriously: "The merger process of massive neutron stars may be very calm, because they may quickly form black holes after collision without having time to release light. ”

Xu Mang was silent for a moment, and then said, "That's it... You can study it by the way, but the main focus is on detecting gravitational waves, and we don't have enough manpower... The graduate students of the Department of Physics at Fufu University have completed their internships and passed their dissertations in my place, and now there is no one left. ”

"Xu Mang?"

"Anyway, you have to recruit some people. Brother Chuan Xiao smiled bitterly: "Add a few of us, there are seven people in total... With such a large institute and a gravitational wave detection laboratory, the result is seven people... It's a bit of a no-brainer. ”

Xu Mang sighed and said silently: "Do you think I don't want to? According to the previous agreement, the Fuhui Conference has always arranged outstanding students to my place for practical training to strengthen research capabilities. ”

Now Xu Mang is difficult to ride a tiger, while there is a serious shortage of manpower, and at the same time, the students of the resumption conference will come over, if the recruitment is full, there will be no place for these students.

"We'll talk about that then. ”

"I'm not in a hurry right now... There's a lot of stuff at hand. Xu Mang said helplessly: "Just take advantage of this window period to solve some things." ”

Brother Chuan Xiao nodded, and then he thought of something and asked, "Have you become the head of the paper review team?"

"Huh?"

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

"Someone has been inquiring about this recently, and they have found me and asked me to ask you to intercede. Brother Chuan Xiao said: "I think someone else was looking for him, and then he found me again, Xu Mang... It's a thankless job, and it's easy to be hated. ”

"Hmm. ”

"It doesn't matter. ”

"I just want to see who has the power to let me get him through. Xu Mang said disapprerovingly: "I'll follow the vine to find this mysterious person, and then arrest him." ”

Afternoon

Xu Mang went to the computer department building, borrowed a supercomputer, and dealt with the universal coverage problem, in order to solve the problem of 0.8441153, continue to shrink this value, Xu Mang designed a complex program for this purpose - atomic scissors.

In the area of 0.8441153, the area that can be trimmed is only atomic, and the process is to automatically generate 20,000 shapes with a width of one in a computer program, stack them together, and then use the shape of the cover as a clue to find out the trimming method for the top of the past universal cover figure.

Simple

brusque

And it works!

Xu Mang roughly estimated that at most by tomorrow morning, he would be able to solve the problem of shrinking the universal coverage area, but at this time, he was curious about the blogger, who was a doctor in the Department of Mathematics of Fuda University.

...

At half past three in the afternoon,

Xu Mang returned home, lying on the sofa and playing games, using the means of connecting the TV series to the computer, playing a horror game "Hong Kong Strange Record", he was attracted by Jiahui's legs inside, although Xiaoman's legs are also quite OK, but unfortunately her height limits her leg length.

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

If you change to a four-year term,

Xu Mang may be about to be sunk into the river... After all, knowing the law and breaking the law will add one degree to the crime.

In fact

This game is not fun, not to mention the rough modeling, just the simple Jumpscare bridge, which makes people feel infinitely disgusted, plus the playability is too low, Xu Mang feels that he has been deceived, but thinking that there are only two people on the production side, it is difficult to judge whether this game is successful or not.

at least

In terms of heat it succeeded.

"Forget it..."

"If you don't get a refund, you should support domestic games. Xu Mang quit the game and went to play another new game, "Tribes and Scimitars", which is far less well-known than the former, but has high playability.

Then

Yang Xiaoman carried six or seven bags and returned home, saw Xu Mang lying on the sofa playing games, didn't pay attention to her, silently came to the kitchen to get a can of diet soda, and then sat next to Xu Mang, watching him play games.

"Wife?"

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

Yang Xiaoman glanced at Xu Mang, and said indifferently: "Anyway, you have been getting lazier and lazier recently, and you were quite diligent before, what's the situation?

Words fall,

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

Xu Mang: ???

Ha?

Is this the difference in radio wave frequency between this and Xiao Man?

I always feel weird lately, she can't understand a lot of words, and menopause has come early?

The quarrel before was also,

It's not about myself and her.,As a result, I quarreled at the door of the restaurant toilet.,But it's normal to quarrel.,How can there be a couple or couple in the world who don't quarrel.,There will always be different opinions.,If you don't express your opinions.,But hold it in your heart.,You'll suffocate yourself.。

Xu Mang said helplessly: "Don't make trouble... Play the game too. ”

broke free from Xiao Man's face-lifting, played "Tribes and Scimitars" by himself, and then let out a pig-like laugh, which deeply stimulated Xiao Man.

I have to sigh,

Xu Mang is walking more and more on the road of death.

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

Tonight

It's time to take back everything from my mother!

Wait for death!

You big pig's trotters!
