Three days later,

The supermassive black hole group at the Xu Yang Research Institute is in an awkward predicament, although several of them are graduates of the physics department, but the physics department of Fuzhou University has an astronomy course, and it is also a compulsory course in theoretical physics, and two of them are from theoretical physics majors in this group.

Pity...

Faced with the problem of the rapid growth mechanism of supermassive black holes, the two are still helpless, and they have never been able to explain the growth rate of the black hole growth model.

Theoretically, a black hole is formed after a massive star runs out of fuel, and if a star has no fuel left to burn, 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 a huge gravitational pull.

As the black hole gradually sucks in nearby dust and gas, it grows in size, eventually reaching a huge proportion of supermassive black holes.

However, this is not the case, and according to the results of the simulations, it is impossible to have an ordinary mass black hole, suck in dust and gas, and then quickly grow into a supermassive black hole, unless a supermassive star collapses to form a 'seed' black hole.

The team's second idea is for a small group of black holes to grow at an incredible rate, or for smaller black holes to merge together and grow into supermassive black holes.

However, in the end, the first point was chosen, and those skyrocketing black holes may have been formed by the collapse of a super-huge star, but unfortunately, according to the information provided by the observatory, there are no stars of this level in the universe at present.

Then the team found a study from two years ago that Australia had discovered the fastest-growing black hole in history, with a mass about 20 billion times that of the Sun and growing rapidly at a rate of one percent per million years.

How to explain it?

I'm afraid this can only be closer to the primordial black hole, otherwise there is no explanation at all.

"Ugh..."

"It's dead!" a young graduate student in the Department of Physics at Fudan University sighed and said with a miserable expression: "I am now more and more inclined to believe that this is the moment of the Big Bang to create the primordial black hole from the outside, otherwise it can't be explained at all." ”

"!"

"The primordial black hole is just a hypothetical black hole put forward by scientists, and it simply cannot exist... Anyway, I don't think it's a primordial black hole, it must be that we didn't observe the details, or that we were going in the wrong direction. A girl with glasses said angrily, "There are less than three days left... Can you do more?"

Come on?

How do you add it?

In the face of this girl's words, the other four boys looked helpless, this is not that or that, there is no way to speak at all.

"Huh?"

"You say... Could it be that Professor Xu himself didn't know, so he left this topic to us to do?" A bold boy frowned and said with a serious face: "I think it's possible... We may have been the ones behind the project. ”

As soon as the voice fell,

Instantly refuted by the other four, the girl with glasses said solemnly: "Do you think the authoritative experts who have two research reports, "Conservation of Information is the Fundamental Law of the Universe: The Mystery of Lost Information" and "The Value of Quasi-periodic Oscillation Signals in Black Holes", need to find a replacement for the dead ghost?"

"I think... Professor Xu, this is testing us, to test whether we are up to the job here. The glasses girl sighed and said helplessly: "It is said that it is a kind of person who can read Fuda, but ... Standing with Professor Xu, we seem to be just mortals, at most we know a little more formulas than others. ”

Time

There was silence in the lab, and no one spoke.

"I think..."

"Let's just confess to Professor Xu, we don't have the ability to study the rapid growth mechanism of supermassive black holes, maybe he can point us out. One of the graduate students in the room said, "There's no shame in that, we really don't know... Instead of wasting on it here, it is better to be honest and explain our shortcomings. ”

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

"Since everyone doesn't want to go, why don't you ... Let's go to Professor Xu, there is an old saying that the law does not blame the public... Even if you are responsible, you can still bear a little bit of it. The boy smiled bitterly and said, "I think this method can be used." ”

And then

A group of people traveled from the Modu Observatory to the Xu Yang Research Institute.

meanwhile

Xu Mang is solving the problem of scattering uncharged neutrons, and after three days of hard work, he found that Gyre-2 needs to build a neutron diagnostic device, which is simply called a neutron spectroscopy instrument in flight, mainly through the measurement of fusion emitted neutron spectroscopy for rapid diagnosis and measurement.

At present, Xu Mang can only do this step, and he can't solve the problem that uncharged neutrons will not be restrained for the time being.

Of course

This device is only temporary, Xu Mang still wants to solve the neutron scattering problem, there is no way... The pride in his heart could not make him accept such a defeat.

"Busy?"

"Come on, come on... Sign it. Brother Chuan Xiao found Xu Mang with the document, and said with a smile: "We have found another double black hole system, and your theory is estimated to be able to be demonstrated in three years, if so... You make history. ”

"Huh?"

"What theory?" Xu Mang asked with a confused expression, "You mean the new Hubble constant?"

"Yes!"

"Originally, this time was fixed in five years, but according to my calculations, it can be done in almost three years. Brother Chuan Xiao said seriously: "Once you get a lot of data, the whole world will accept your new Hubble constant." ”

"Oh... Whatever. Xu Mang responded indifferently: "Three years later... Maybe I'm going to be a dad. ”

Sun Chuanxiao: ???

Belch?

So fast?

"You... You're going to be a father so soon?" Brother Chuan Xiao said with a look of horror: "Indeed... I noticed that you haven't smoked lately, so you don't really plan to have children, are you? You're so young... Have you just stepped into the grave of marriage and are about to go to hell when you turn around?"

"Ugh..."

"My mother and mother-in-law are urging tightly, and they can't wait to hold the baby tomorrow morning. Xu Mang said helplessly: "If it's just the second elder, forget it, you can get rid of it if you're busy with work, the problem... Xiaoman also wants to be a mother, what can I do?"

Brother Chuan Xiao frowned, and asked seriously, "Xu Mang... You're going to be finished!"

Xu Mang: Embarrassed

After Brother Chuan Xiao left, Xu Mang was in no mood to continue his research, and he was paralyzed on the chair alone, what the hell should I do?

Bang bang bang!

suddenly

There was a quick knock on the door from the office, and after a call to enter, Xu Mang saw that all the members of the black hole team, with a trace of helplessness and sadness, walked into the office, judging from the mental state of these people, it is estimated that they have come to ask for help.

"What's wrong?"

"One by one, as if they were going to be shot..."Xu Mang asked curiously, "Tell me about the situation." ”

"Professor Xu... We... We estimate your expectations, and there is nothing we can do about the mechanism of rapid growth of supermassive black holes, and we can't find any solution to it. The girl with glasses said helplessly.

"Oh..."

"It turned out that this was the case, and I had expected it a long time ago. Xu Mang smiled and said, "Show me your research report, I want to know about your progress." ”

moment

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

Inserting the mobile data disk, Xu Mang glanced at the contents inside, and after only a few minutes, he raised his head and smiled: "The idea is still good, but the idea is wrong." ”

"Huh?"

"What do you mean?" said the bespectacled girl.

"Who came up with the primordial black hole?" Xu Mang asked curiously, "There is some!"

"Uh..."

"Xu... Professor Xu is me!" A boy said cautiously, "Isn't there some?"

"It's okay. ”

"Research is all about imagination. Xu Mang said seriously: "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 them with imagination." ”

Then

Another male student in the crowd asked, "Professor Xu... What the hell is going to be done?"

"Don't rush. ”

"Show me what you're gathering. Xu Mang said seriously: "Give me an hour." ”

An hour?

Only... That's it?

That's not a joke, is it?

"Ahem!"

"Professor Xu... Can you let us stay in the office?" the boy said cautiously, "We... We want to see how exactly you get it done. ”

"Oh..."

"Whatever you want. Xu Mang said indifferently.

moment

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

Soon after,

Xu Mang found a NASA document, which appears to have been released by the Chandra X-ray Observatory, that discovered a so-called invisible black hole, which, according to the above data, rapidly grew into a giant form when the universe was only six percent of its current age.

Belch...

This should be it!

"It's solved!" Xu Mang said indifferently.

“？？？”

“？？？”

“？？？”

What the?

This... It's only been five minutes, and it's... Just solve it?

Just kidding, right?

"Xu..."

"Professor Xu?"

"You... Are you kidding?" the bespectacled girl asked in horror, "This... It's only been fifteen minutes, and it's... It's solved?"

Xu Mang smiled and said seriously, "Too long?"

"No, no, no!"

"It's... This is too short, there are five of us..."The glasses girl smiled bitterly: "Professor Xu... How to solve the problem of the rapid growth mechanism of supermassive black holes?"
