Chapter 751

Three days later,

the supermassive black hole group of Xuyang Research Institute was in an awkward predicament. Although several of them graduated from physics department, the Physics Department of Fuda has astronomy courses and is a required course in theoretical physics. Two of them are from theoretical physics.

Unfortunately...

facing the problem of the rapid growth mechanism of supermassive black holes, they are still at a loss. They still can't explain the growth rate of the black hole growth model. How did this supermassive black hole come into being? Why grow up so terrible quality.

According to theory, a black hole is formed when a star runs out of fuel. If a star does not burn any more fuel, it can no longer support its mass and collapse. If the mass of the star is large enough, it will collapse into an object with great gravity.

As the black hole gradually sucks in the dust and gas nearby, its size will continue to increase, and eventually reach the huge proportion of the supermassive black hole.

However, this is not the case. According to the simulation results, it is impossible to have a common mass black hole unless the super massive star collapses to form a "seed" black hole.

And the team's second idea is that a small number of black holes grow at an incredible rate, or that smaller black holes merge together and grow into supermassive black holes.

However, the first view was finally selected. Those black holes may have been formed by the collapse of a super giant star. Unfortunately, according to the information provided by the observatory, there are no such stars in the universe at present.

Then the team members found a research report two years ago. Australia discovered the fastest growing black hole in history. Its mass is about 20 billion times that of the sun, and it is growing rapidly at the rate of 1% per million years.

How to explain it?

I'm afraid this can only be close to the original black hole, otherwise it can't explain why.

"Alas..."

"dead!" A young graduate student in Physics Department of Fuda sighed and said miserably: "I am more and more inclined to create a primary black hole from external pressure at the moment of the big bang, otherwise it can't be explained at all."

"Bullshit!"

"The primal black hole is just a hypothesis put forward by scientists, and it can't exist at all... In short, I don't think it's the primal black hole. It must be that we didn't observe the details, or our direction was wrong." A girl with glasses said angrily, "there are less than three days left... Can you work harder?"

Come on?

How to add it?

In the face of this girl's words, the other four boys are helpless. This is neither that nor that. There is no way to speak at all.

"Ah?"

"Do you think it's Professor Xu who doesn't know it himself, so you leave this subject to us?" A bold boy frowned and said seriously, "I think it's possible... We may become the backers of this project."

As soon as the voice dropped,

she was refuted by the other four people. The girl with glasses said solemnly, "do you think the authoritative experts who have two research reports, namely, the conservation of information is the fundamental law of the universe: the mystery of lost information" and "the use value of quasi periodic oscillation signals in black holes", need to replace the dead ghost

"I think... Professor Xu is testing us to see if we can do the job here." The glasses girl sighed and said helplessly, "it is said that those who can read and restore university are the favored ones. But... Standing in the professors Xu, we seem to be just ordinary people. At most, we know a little more formula than others."

For a moment,

there was silence in the laboratory, and no one spoke.

"I think..."

"to confess directly to Professor Xu, we do not have the ability to study the rapid growth mechanism of supermassive black holes. Maybe he can give us some advice." "It's not a shame at all, we really don't know... It's better to be frank and explain our shortcomings than to work here," said a graduate student present

In the face of this proposal, it was quickly accepted by everyone, and then a question arose. Who is going to confess all this to Professor Xu?

"Since everyone doesn't want to go, we'd better... Go to see Professor Xu together. As the old saying goes, the law does not blame the public... Even if we are responsible, we can bear a little bit." The boy said with a wry smile, "I think it's OK."

Then,

a group of people went to Xuyang Institute from Mordo observatory.

At the same time,

at the same time,

Xu mang is solving the problem of the scattering of uncharged neutrons. After three days of hard work, he found that he needs to establish a neutron diagnostic device, which is simply called the neutron energy spectrum instrument in flight, which is mainly used for rapid diagnosis and measurement through the measurement of fusion emission neutron spectrum.

At present, Xu mang can only do this step, he can not solve the problem that the neutral neutrons will not be bound.

Of course,

this device is only temporary. Xu mang still wants to solve the neutron scattering problem, but he can't help it. His inner pride can't make him accept such a failure."Busy?"

"Come and come... Sign." Chuanxiao found Xu mang with the document and said with a smile: "we have found another double black hole system. Your theory is estimated to be able to be demonstrated in three years. If so, you will create history."

"Ah?"

"What theory?" "You mean the new Hubble constant?" Xu asked with a confused face

"Yes

"Originally, this time was fixed in five years, but according to my calculation, it can be completed in almost three years." Chuanxiao said seriously: "once we get a lot of data, the world will accept your new Hubble constant."

"Oh... Whatever." "Three years later... Maybe I'll be a father," Xu said calmly

Sun Chuanxiao:???

Eh?

So fast?

"You... You're going to be a father so soon?" Chuanxiao said with a look of panic: "indeed... I found that you don't smoke any more recently. Do you really plan to have children? You're so young... You've just entered the grave of marriage, and you're going to hell. Are you crazy? "

"Alas..."

"my mother and mother-in-law are so anxious that they can hold the baby tomorrow morning." Even if Xu Xiaoman is busy, how can I do it

Chuanxiao frowned and asked earnestly, "Xu mang... You're going to die!"

Xu Mang: Jiong

after brother Chuanxiao left, Xu mang was not in the mood to continue to study. He collapsed in a chair. What should I do?

Bang bang!

All of a sudden,

there was a sudden knock on the door of the office. After an invitation, Xu mang saw all the members of the black hole group walking into the office with a trace of helplessness and sadness. Judging from the mental state of these people, it is estimated that they are coming for help.

"What's the matter?"

"One by one, as if to be shot..." Xu blankly asked curiously: "talk about the situation."

"Professor Xu... We... We have failed to live up to your expectations. There is nothing we can do about the rapid growth mechanism of supermassive black holes. We can't find any solution." The girl with glasses said helplessly.

"Oh..."

"it turns out to be this thing, I had expected it for a long time." Xu mang said with a smile: "show me your research report. I want to know about your progress."

For a moment,

the girl took out a mobile data disk, handed it to Xu Mang and said, "it's all in it."

Insert the mobile data disk, Xu mang looked at the contents inside, only after a few minutes, raised his head and said with a smile: "the idea is still good, but the idea is wrong."

"Ah?"

"What do you mean?" The girl with glasses said.

"Who thought of black holes in the early days?" Xu mang asked curiously, "there are some bullies!"

"Er..."

"Professor Xu... Xu is me!" A boy carefully said, "is there some bullshit?"

"Not bad."

"Scientific research is about imagination." Xu mang seriously said: "without these wild imagination, it is impossible to go too far. The reason why we can have such a life is to rely on imagination, and then realize the imagination."

At this time,

another boy in the crowd asked, "Professor Xu... What should we do about this?"

"Don't worry."

"Show me your collection." "Give me an hour," Xu said seriously

An hour?

Just... It's done?

This is not a joke, is it?

"Cough!"

"Professor Xu... Can we stay in the office?" The boy said cautiously, "we... We want to see how you did it."

"Oh..."

"whatever you want." Xu mang said calmly.

After a while,

Xu mang got the data collected by the black hole team, not to mention... Although his research ability is not very good, this collection ability is very strong, basically there is no problem.

Not long ago,

Xu mang found a NASA data, which seems to have been released by the Chandra X-ray Observatory. They found a so-called invisible black hole. According to the above information, when the universe is only 6% of its current age, it rapidly grows into a big Mac.

Er...

this should be it!

"It's solved!" Xu mang said calmly.“？？？”

“？？？”

“？？？”

What?

This... It's only five minutes, and it's solved?

Are you kidding?

"Xu..."

"Professor Xu?"

"Are you... Are you kidding?" The girl with glasses asked in horror, "this... It's only 15 minutes, and it's solved?"

Xu mang laughed and said seriously, "too long?"

"No, no, no!"

"This... This is too short, five of us..." the girl with glasses said with a wry smile: "Professor Xu... How to solve the problem of the rapid growth mechanism of supermassive black holes?"
