Xu Mang looked at his mobile phone, he didn't know what to do for a while, he had already fought against fate, but in the end he still failed, I have to say... Men are reliable, pigs can climb trees, and I originally thought that I had established a deep friendship with Ding Jun.

As a result, someone else made a phone call, and this friendship was gone...

"Hello?"

"Xiao Man?" Xu Mang finally answered the phone and asked cautiously, "What's wrong?"

"Nothing... I just want to ask you if you've been short of money lately?"

is not as manic as imagined, but it is unusually stable, and even asked if he is short of money.

This...

Is this Yang Xiaoman?

"I'm short of money. Xu Mang said seriously: "It's too short." ”

"Hmm..."

"I'll give you a little more after that... Your pocket money in the future has risen to 10,000. Yang Xiaoman said gently: "If it's not enough, you can continue to rise, of course, you need to approve it in front of me, and you have to combine your performance." ”

"Huh?"

"Xiao Man?" Xu Mang said worriedly, "Did your brain be crushed by the door panel?"

"Nasty!"

"You're just squeezed by the door. Yang Xiaoman said angrily: "That's it... But is there anything you want to say to me?"

“...”

"No!" Xu Mang was ruthless and pushed himself to the brink of death again.

After you hang up,

Xu Mang was in a dream, but this dream did not last long, and he was slapped in the face by reality.

First of all

He has to deal with a black hole problem, and the second is to solve what kind of world he will encounter after entering a black hole, but according to the screenwriter's meaning, people will reach a higher dimensional universe after entering a black hole, that is, they have traveled through time and space.

This one...

There's no denying that imagination is abundant, but it's impossible.

According to the two schools of modern physics, quantum theory defines the inside of a black hole as a wall of fire, and people will be reduced to ashes when they enter it, while from the theory of relativity, as long as people get close to the black hole, they will be torn apart by gravity.

Anyway, it's all dead...

Five-dimensional space...

Xu Mang has not done much research on dimensional space, and he plans to ask Lisa Landall, an expert in this area, about dimensional space.

Finally, on the issue of wormholes,

Xu Mang thinks that wormholes do not exist, and there is no evidence that there is such a thing as wormholes in the universe, but the movie must have wormholes to promote the plot, which... This is the end of the again, how to build a model for this wormhole?

In desperation,

Xu Mang found his good buddy of the same style, Brother Chuan Xiao, an Internet expert, as a researcher at the Modu Observatory in the past and a researcher in black hole physics, there should be no problem.

Simply told Brother Chuan Xiao about the request, and the two decided to start the research the next day, because Brother Chuan Xiao had resigned from his job as a researcher at the Modu Observatory, but he copied all the data, although it was not kind to do so, but the data itself did not belong to the Modu Observatory.

"Xu Mang?"

"How long does it take?" asked Brother Chuan Xiao.

"Uh..."

"A month. Xu Mang said: "But I want to hurry, it's best to finish this matter before the laboratory is completed, otherwise it will be too tiring to wear multiple hats." ”

"That requires an office space. Brother Chuan Xiao said: "The formaldehyde in the laboratory has not yet been volatilized, and the danger of working in the laboratory is too high, so it is better to find a safe place to work." ”

This,

Xu Mang and Brother Chuan Xiao have similar views, health is the most important.

Afternoon

Xu Mang returned to his apartment, pushed the door and saw Yang Xiaoman lying on the sofa, seemingly scrolling Weibo, seeing her calm appearance, Xu Mang breathed a sigh of relief, although he didn't know what happened, but at present, he was safe.

"Coming back?"

"I'll make you a sandwich?" Yang Xiaoman glanced at Xu Mang: "There happens to be a can of tuna." ”

"I want a ham sandwich. Xu Mang said.

"Okay, husband. ”

Yang Xiaoman smiled, put down his mobile phone and went to the kitchen, at this time Xu Mang came to the sofa with a chirp, and just sat down and noticed the mobile phone on the coffee table, and the content on it made him shudder.

Here's a report... The title reads that the husband was stabbed more than 20 times by his wife for hiding private money, and finally died.

Xu Mang:( ̄△ ̄;)

This...

Why do you suddenly watch this kind of news?

Of course, Xu Mang didn't dare to say or ask, because he had a ghost in his heart.

soon

The so-called ham sandwich is made, in fact, it is to take out the ham slices from the refrigerator, put them directly in it, put a few lettuce leaves, smear a little mayonnaise and finish the work, and do not even need to turn on the fire, which is quite friendly to Xiao Man, she has found the joy of making delicious food.

“...”

"Xiao Man?" Xu Mang watched Xiao Man shopping on a shopping website, but what she bought was a fruit knife, combined with the previous news... Xu Mang almost ran out of urine.

"Huh?"

"You... What are you buying knives for?" asked Xu Mang.

"Just take a look. Yang Xiaoman raised his head and said with a smile: "Don't worry, I'm not here to stab you, you didn't hide your private money." ”

In the strong aura and the weakness of being a thief, Xu Mang finally confessed his behavior of making false accounts.

"Xiao Man..."

"I gave you a false account. Xu Mang rubbed his head and said cautiously: "Actually, I made two million dollars." ”

however

This number did not satisfy Xiao Man, at this time she said seriously: "Is it less?"

"Huh?"

"No, I don't. Xu Mang was stunned for a moment, and asked curiously, "It's indeed this number." ”

"Less!"

"Half a million less. Yang Xiaoman said solemnly: "Shouldn't it be two and a half million?"

Two and a half million...

It was indeed two and a half million, but the middleman took half a million.

Ding Jun took 500,000 yuan and said what kind of introduction fee it was. Xu Mang explained: "I can't help it, this guy is getting more and more chicken thieves, maybe he has lived in the United States for too long and has been contaminated with some capitalist breath." ”

Then

Xiao Man, who was originally frowning, stretched out and smiled at Xu Mang: "I'll help you come back." ”

But without waiting for Xu Mang to express his admiration, Yang Xiaoman said with a dark face: "The death penalty can be avoided, the living crime is inescapable, you can sleep on the sofa tonight!"

Not to mention,

Since the sofa was bought, Xu Mang wanted to try the feeling of sleeping on the sofa, and finally kept dying, and had the opportunity to experience the sofa this time.

The Sprinkle family is worth it in this life!

...

Following

Xu Mang found Brother Chuan Xiao, and with his relationship, the two temporarily borrowed the office of the Modu Observatory to study the astrophysics in the movie.

"it!"

"100 million times the mass of the sun?" After Brother Chuan Xiao heard this request, he almost didn't pee, what is the concept of this 100 million times the mass of a black hole... The mass of the largest black hole in the Milky Way is four million times the mass of the sun, which is 100 million times... It's kind of scary.

"Yes. ”

"And that's not the point... It is to exist in isolation from this universe. Xu Mang smiled bitterly: "It is also visually shocking." ”

In fact

Xu Mang can do special effects, and he triggered this skill before, but now it's not a problem with special effects, he himself doesn't know what this kind of black hole looks like, there was a real black hole photo before, but it's a pity that it's too blurry.

"Xu Mang?"

"I do know of a suspected black hole object that's pretty much what you'd expect. Brother Chuan Xiao said seriously: "This is an active celestial body, located near Markarian 177, and the current evidence shows that this is a black hole that has been kicked out. ”

Kick out?

Xu Mang was stunned for a moment, although there was a possibility that the black hole was kicked out, no one observed that the black hole was raised in the galaxy.

In the end, Xu Mang decided to make a model first, and then constantly make corrections on this model, trying to meet the requirements while taking into account the basic astronomical and physical knowledge, so as not to be found by the bar.

It took the two of them an hour to complete the envisioned black hole, but it seems that this black hole is too hardcore for now.

"Or we'll cancel Hawking Fallout. Xu Mang frowned and said: "Although the existence of Hawking radiation increases the visual impact, according to the plot of the movie, the protagonist is going to enter the inside of the black hole." ”

"That's fine. ”

"But... What about the substances in the surrounding accretion disk?" said Brother Chuan Xiao: "A black hole that exists in isolation, without swallowing other matter, how can these substances be explained?"

depend on

I don't know!

Xu Mang's face was full of the word 'sad urging', and he really didn't know how to explain it.

However, it can explain why the material in the accretion disk is not sucked in, and there is a paper in the journal "Nature Physics" entitled "The Value of Quasi-Periodic Oscillation Signals in Black Holes", which describes the existence of a stable orbit near a black hole.

"Let the writers make it up themselves. Xu Mang said helplessly: "We gave them a few choices, the first is that this black hole has swallowed one or two medium-sized galaxies, the second is that this black hole has swallowed a large number of wandering planets, and the third has swallowed a gas cloud. ”

truly

This requires imagination, but Brother Chuan Xiao is quite satisfied with the few guesses made by Xu Mang, and the first of them is more likely.

"This suction cup..."Xu Mang pointed to the suction cup filled with a large amount of substance, frowned, and said, "Isn't it... I always feel wrong, Brother Chuanxiao... We need to do more research to present the most realistic and shocking model of black holes. ”

Authentic...

It's so hard!

The previous picture of the black hole is real enough, and it turns out to be burning honeycomb coal.

What the movie wants to express is to stand on the edge of the black hole and see the huge black hole with your own eyes, which is too difficult, and many theories about black holes are currently on paper, how can it be true.

subsequently

Xu Mang and Brother Chuan Xiao finally knew why this suction cup was a little strange, because the whole black hole looked too smooth without a lens that took into account the gravitational field, but if a gravitational lens was added, then the curvature of the Einstein effect would become incalculable.

Xu Mang took out the first photo of the black hole and carefully observed the burning honeycomb coal, this real photo, one side is bright, the other side is dim, this is the effect of Doppler frequency shift, then he should also take into account Doppler frequency shift.

But...

That's not shocking enough!

"Xu Mang?"

"Are others still rendering it like you?" After Brother Chuan Xiao saw Xu Mang's black hole model, he said helplessly: "Around the horizon... This aperture... How much does it cost to render?"

"They have money. Xu Mang smiled: "Anyway, I provide the most correct black hole model, and the others have nothing to do with me, right... Do you think it makes sense to think that the curvature of the suction cup under the gravitational lens?"

Brother Chuan Xiao glanced at it and said seriously: "It's a bit exaggerated, you will definitely be sprayed to death by the bar spirits like this." ”
