To a large extent, fame and status occupy most of the right to speak, at least for Xu Mang, when the publisher of the paper is not Xu Mang, but XY Labs, he stands on the opposite side of everyone.

Even if his opinion is correct, he is not as famous as NASA, and everything he says is wrong in the eyes of others.

And

Couldn't be more wrong.

Xu Mang took a look at his criticism on Weibo, most of which were self-media marketing accounts, frantically boasting about how epoch-making this NASA discovery is, and how much of a role it has played in today's physical enlightenment, which can almost go down in history.

However... As a professional, Xu Mang can't see the so-called epoch-making significance.

These bad media know how to blow nonsense...

Then

The phone rang,

It was a call from Xiao Man.

"Hello?"

"Big stupid!" Yang Xiaoman said angrily: "XY, do you use the name of our son, Xu Yang?"

“...”

"What kind of association are you? Xu Mang said with a black line on his face: "I just took the capitalization of the surnames of the two of us, how can I have something to do with my son, your ass is so small, how can you give birth to a son." ”

Hearing Xu Mang's words, Xiao Man was angry, and scolded angrily: "The old lady can't have a caesarean section, are you annoying?

"Yes. ”

"I just saw it. Xu Mang leaned back in his chair and said with a smile: "I think this NASA paper is well written, and many of the views are in line with mine." ”

"This..."

"Are you cowardly?" Yang Xiaoman asked in disbelief: "Shouldn't you be like a thunderbolt and then fight back?"

"I can't find the other party's shortcomings for the time being, judging from the mathematical logic, he is right. Xu Mang said embarrassedly and politely: "Don't panic... Give me half a day and it should be no problem. ”

"Hmm..."

"I uninstalled Weibo temporarily, hello and tell me, I'll download it again. Yang Xiaoman said: "I almost didn't make my wife angry when I just swiped Weibo." ”

“...”

"You..."Xu Mang said helplessly: "Anyway, others don't know it's me, so it doesn't matter." ”

"Cut!"

"Anyway, it's not good to watch. Yang Xiaoman smiled and said, "Alas... Is your wrecked car with no air conditioning still there?"

"A must!"

"This is an out-of-print Porsche GT2RS, and it's no longer available. Xu Mang said seriously: "This is my second wife, don't make a bad idea." ”

Yang Xiaoman snorted coldly and hurriedly asked, "When will you help my father's company?" Recently, he was made to come home late every day by some chip materials, and my mother has a lot of opinions about it. ”

"Oh..."

"When I come back from Oxford University, I'll help my dad get this chip material done. Xu Mang said seriously: "Don't worry... I'm here. ”

“...”

"Wait a minute!" Yang Xiaoman reacted and asked curiously, "Where did you say you came back from?"

"Huh?"

"Didn't I tell you about the experiments at Oxford University in the past?" Xu Mang was stunned for a moment, and said with a squeak: "No... I said hello to you in my dreams, but did you forget in my dreams?"

Yang Xiaoman: @#¥%...&*

"I'll tell you in the evening, now I have something to deal with. ”

didn't give Xiao Man any chance to speak, Xu Mang hung up the phone directly.

Thoughts back to the question,

How can pure mathematics be used to prove that a swinging accretion disk really exists in the universe?

In fact

This question is not difficult at all, you only need to know the angular momentum of this neutron star, but at present this value is not known, if you know this angular momentum and calculate the gravitational difference between the star and the neutron star, you can know whether it is swinging or not.

In general, they are either spherically symmetrical or axisymmetric.

If this asymmetry exists,

Another major earthquake in the field of astrophysics.

"Hello?"

"Brother Chuanxiao... Can you help me find the angular momentum values for neutron stars in the MAXI J1621501 binary star system?" Xu asked, "I need an approximate value." ”

"This..."

"Our equipment is not working. Brother Chuan Xiao said seriously: "It is possible for ESA's equipment to do this, but they will not be so boring. ”

"Oh..."

Xu Mang thought for a moment and said seriously: "Then I'll push it myself, calculate this value, and let them observe it by themselves." ”

Words fall,

Hung up.

Followed by

Xu Mang began to add an unknown angular momentum to it according to the content of "The Ridiculous Neutron Star Swinging Accretion Disc", and deduced this calculation process from zero, and after an hour and a half of continuous calculation and verification, Xu Mang roughly came up with a value.

Not precise enough, but barely works.

however

Xu Mang also wanted to try it, according to the concept of the rocking accretion disk, Xu Mang felt that there was another phenomenon in the universe, the swinging jet of the black hole, and the black hole's suction plate was in an asymmetrical structure.

Not to mention,

In the ESA's database, Xu Mang found a paper on observation data thirty years ago, which was the black hole data in the V404 binary system, when the black hole spewed out a large amount of high-energy matter and radiation.

Later, Xu Mang found a paper by an ESA intern, which contained data on this black hole that had been dormant for 26 years and began to explode again.

In his paper, Xu noted that this light source behavior is intermittent and continuous.

In this regard,

Xu Mang thinks that this is the swinging jet of a black hole.

In order to test his idea, Xu Mang, similar to before, built a corresponding black hole ejection model, in which the black hole is devouring the companion star, sucking matter into its accretion disk, and then some of the material in the disk is ejected out.

Because for some reason, the black hole is not aligned with its own accretion disk, causing the interior of the disk to wobble like a rotating top that is decelerating, and eject high-energy ions in different directions as the direction changes.

subsequently

It was a demonstration of Xu Mang's mathematical ability, and the process took him an hour.

"Call it a day!"

"So be it. Xu Mang looked at his two papers, and didn't bother to revise them, so he directly posted them on the website of the Princeton Astrophysical Society in the name of XY Laboratory.

...

ESA，

ESA.

It's an official organization dedicated to space exploration, but lately many people in this organization have been looking at NASA, an expert in the field of neutron stars, who recently got into a relationship with an obscure laboratory.

This incident has become a topic of conversation after dinner.

thereinto

Professor Chester and Professor Carter, who also study neutron stars, are the people who are most concerned about this matter, but the two did not make a sound, just waited quietly, but unfortunately the XY lab seems to have disappeared.

"Ugh..."

"What a pity!"

In the lounge,

Professor Carter drank his coffee and said to his colleague Chester in front of him: "This XY lab seems to have disappeared, but the idea is very novel and bold. ”

"Hmm!"

"It's a bold and interesting point, but it lacks some foundation and evidence. Chester smiled: "You said this XY lab, whose laboratory is it?"

"I don't know. ”

"It always feels like this lab is mysterious. Carter said seriously: "Maybe someone is pranking, there is no such lab at all." ”

Then

Another colleague rushed to find two.

"Quick!"

"XY Labs has sent two papers!" the colleague said hurriedly.

“？？？”

“？？？”

This...

I just talked about it, and this is what happened?

With the help of an intern's laptop, Carter landed on the website of the Princeton Astrophysical Society and quickly found two papers from XY Labs.

"Serious Neutron Star Swinging Accretion Disc"

Black Hole Swinging Jet of Existence

What's the situation?

How did black holes come into contact again?

The two of them were full of confusion, but they still clicked on "Serious Neutron Star Swinging Accretion Disc" first, this paper is very pertinent, obviously aimed at NASA, according to the calculation process given by the researcher at NASA, it was re-deduced.

Thus a valuation angular momentum is obtained.

“...”

“...”

Neither of them spoke, and if this estimate is correct, I am afraid that there really is a constantly swinging accumulation cup in the universe, because the angular momentum is different from the gravitational pull of the star, and according to the calculation, there is indeed an unstable gravitational field.

"This..."

"How was this derived?" Carter watched in horror at the calculations, it was too complicated... It's so complicated that it's crushing.

"I'm getting more and more curious now... Who exactly is this XY Lab. Chester said seriously: "Anyway, we can observe the angular momentum of this neutron star, perhaps... Miracles can really happen. ”

"Have you figured it out?" said Carter earnestly, "This is a big project!"

"I know. ”

"But it's worth a try. Chester laughed, "Don't you want to see the helpless look on the face of the guy at NASA?"

Kart nodded, "If you say that, I really can't wait." ”

Followed by

Carter and Chase started the second paper published by the XY Institute, titled "The Existence of Black Hole Swinging Jets"...

moment

The two were in a state of confusion.

V404？

Isn't this a binary star system that we discovered at ESA?

As they continued to delve deeper into the paper, they gradually realized that something was wrong, and it was not until the later calculation part that the two of them reacted.

At this time, the two of them were already shocked to the point of speech, the V404 binary star system, although after many years, can see this special number, the memory is still back to the past, when an intern of ESA conducted a deep observation of the V404 binary star system, and the result was a shocking picture.

The plasma ejected by this black hole is flowing out in clumps.

A lot of people talked about it, but it didn't attract much attention, after all, the ESA was in a sad atmosphere at the time, and the comet Rosetta probe was damaged and lost contact with the ground.

however

I never thought that

The problem left over from history has been solved at this time today.

"Hello?"

"Div!" Carter called a black hole expert from the ESA and said solemnly: "On the website of the Princeton Astrophysical Society, there is a paper called "Black Hole Swinging Jets of Existence", you can quickly take a look and see if it is correct!"

Ten minutes later,

Professor Carter's cell phone rang, and the caller was the black hole expert.

"Carter!"

"Do you know who this registrant 'XY Labs' really is?!"
