I really don't want to lie down and win

Tired ass!

Lying on the sofa and playing games all day, I don't look tired at all.

Yang Xiaoman said angrily: "You said... did he have someone outside? Wasted all his energy outside? He used to hand in his homework in a timely manner, but now it's getting later and later."

Zhou Weiwei: °ー°〃

Xiaoyi: °ー°〃

This... It's hard to say!

How to do?

"Tell me quickly...don't keep silent." Yang Xiaoman said seriously: "Actually, I don't really believe that my husband has someone outside. He... usually careless, no one should Some appearance, but he is very loyal to me."

"That..."

"Xiaoman... How long have you been with Professor Xu Mang?" Zhou Weiwei asked in a low voice.

Yang Xiaoman hurriedly said, "It's been more than four years."

"..."

"The seven-year itch, the seven-year itch, there is no need for seven years in this society." Zhou Weiwei said: "Two or three years is almost the same, some people even end in a year or a half, don't they... Professor Xu Mang no longer has the same impulse towards you?"

Yang Xiaoman frowned, thinking for a long time, it should be impossible... After all, my mother is the most beautiful in the world.

At this time,

Xiao Yi, who had been silent all this time, suddenly said, "Xiaoman...can I say a few words?"

"You speak!"

"Are you usually too conservative?" Xiaoyi said: "Marriage needs to be managed. In the firewood, rice, oil, salt, soy sauce and vinegar tea, you need to add some other fun, and this fun is...to let the other party get a sense of freshness."

words fell,

Xiao Yi asked seriously: "How long has it been since you bought the clothes inside?"

"..."

"I haven't bought anything recently. The company has too many things to do, and I can't keep up with it." Yang Xiaoman said helplessly.

"OK!"

"The problem has been found!" Xiaoyi said hurriedly: "This is the reason for Professor Xu Mang's avoidance. You have to let Professor Xu Mang feel fresh and at the same time maintain a sense of mystery. Only in this way... can he always be by your side , I can’t shake it off.”

Yang Xiaoman pondered for a long time, then suddenly stood up, took the hands of the two, and walked outside.

"go!"

"Accompany me to buy clothes, you can help me refer!"

That's right!

I'm going to let the big idiot know what charm is tonight!

......

Chapter 821 Take back everything my mother has! (1/3)

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 [-] times that of the sun. The largest known binary neutron star system weighs half the mass of the sun."

"what?"

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 thought it might 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." Over time, density fluctuations in the universe formed the oldest black holes of this kind."

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 number of primordial black holes Enough really 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.”

"is it?"

"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."
