Xu Mang looked at his mobile phone and didn't know what to do for a while. He had fought against his fate, but he failed in the end. I have to say... a man is reliable, and pigs can climb the tree. He originally thought that he and Ding Jun were established. A deep friendship.
As a result, if someone calls, the friendship is gone...
"Hey?"
"Xiaoman?" Xu Mang finally answered the call and asked cautiously: "What's wrong?"
"Nothing... I just want to ask if you are short of money recently?"
Not as mad as he thought, but unusually stable, and even asked if he was short of money.
This...
This is Yang Xiaoman?
"Lack of money." Xu Mang said seriously: "Lack of money."
"Ok..."
"Then I'll give you a little more... Your future pocket money has risen to 10,000." Yang Xiaoman said softly: "If it is not enough, you can continue to increase it. Of course, you need to approve it in front of me. Combine your performance."
"what?"
"Xiaoman?" Xu Mang said worriedly: "Did your mind be squeezed by the door panel?"
"hate!"
"You were squeezed by the door panel." Yang Xiaoman angrily said: "Let's do it... But what do you want to say to me?"
"..."
"No!" Xu Mang was cruel and pushed himself a step closer to death.
After hanging up,
Xu Mang was in a dream, but this dream did not last long, and was slapped in the face by reality.
First of all,
He has to deal with a black hole problem. Second, he has to solve what kind of world he will encounter after entering a black hole. However, according to the screenwriter, after entering a black hole, a person will reach a higher-dimensional universe, that is, through time and space.
This one...
There is no denying that the imagination is rich, but it is impossible.
According to the two schools of modern physics, quantum theory defines the interior of a black hole as a wall of fire. People entering it will be turned into ashes. From the perspective of relativity, as long as people approach the black hole, they will be torn apart by gravity.
Anyway, it's dead...
Five-dimensional space...
Xu Mang has not done much research on dimensional space. Regarding dimensional space, he intends to ask Lisa Randall, an expert in this field.
Finally, about the wormhole problem,
Xu Mang believes that wormholes do not exist. There is no evidence to prove that there are wormholes in the universe, but the movie must have wormholes to promote the plot. This...this is all over again. How should this wormhole be established? Related model?
Without any choice,
Xu Mang found his own good buddy, the Internet expert Chuan Xiaoxiong. As a researcher of the Magic City Observatory and a researcher of black hole physics, there should be no problem.
After simply talking to Brother Chuanxiao about their requirements, the two decided to start the research the next day. Brother Chuanxiao had quit his job as a researcher at the Magic City Observatory, but he copied all the data. Although it was not kind, these The data itself does not belong to the Magic Observatory.
"Xu Mang?"
"How long will it take?" Brother Chuan Xiao asked.
"Uh..."
"One month." Xu Mang said: "But I want to hurry up. It's best to finish this matter before the laboratory is completed, otherwise it will be too exhausting to do several jobs."
"That needs an office location." Brother Chuan Xiao said: "The formaldehyde in the laboratory has not been completely volatilized. It is too harmful to work in the laboratory. It is better to find a safe place to work."
at this point,
Xu Mang and Chuan Xiao have similar views, and health is the most important thing.
in the afternoon,
Xu Mang returned to his apartment, pushed the door and entered, and saw Yang Xiaoman lying on the sofa, seeming to be scanning Weibo, and seeing her calm face, Xu Mang breathed a sigh of relief, although he didn't know what happened. What, but so far, everything is fine.
"came back?"
"I'll make you a sandwich?" Yang Xiaoman glanced at Xu Mang: "It happens to have a can of canned tuna."
"I want to eat a ham sandwich." Xu Mang said.
"good husband."
Yang Xiaoman smiled, put down his cell phone and headed to the kitchen. Xu Mang chirped to the sofa. He just noticed the cell phone on the coffee table, and the content on it made him shudder.
This is a report... The title reads that the husband was stabbed by his wife for more than 20 times for hiding private money, and eventually died.
Xu Mang: ( ̄△ ̄;)
This...
Why do you watch this kind of news suddenly?
Of course Xu Mang did not dare to speak or ask, because he had a ghost in his heart.
quickly,
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, and wipe a little mayonnaise to finish the work. It is very friendly to Xiaoman. She has found it. The joy of food.
"..."
"Xiao Man?" Xu Mang looked at Xiao Man who was visiting a shopping site, and the thing she bought was a fruit knife. Combined with the previous news... Xu Mang almost didn't urinate.
"Uh?"
"You...what did you buy a knife for?" Xu Mang asked.
"Just take a look." Yang Xiaoman raised his head and said with a smile: "Don't worry, I didn't come to stabbing you, you didn't hide your private money."
With a strong aura and a guilty conscience with himself, Xu Mang finally confessed his act of making false accounts.
"Little Man..."
"I gave you a false account." Xu Mang pulled his head and said cautiously: "Actually, I made two million dollars."
however,
This number did not satisfy Xiaoman. At this time, she said seriously: "Is it less?"
"what?"
"No." Xu Mang was taken aback, and asked curiously: "It is indeed this number."
"not enough!"
"It's half a million less." Yang Xiaoman said solemnly: "Should it be 2.5 million?"
2.5 million...
It was indeed 2.5 million, but the middleman took away half a million.
"Ding Jun took away half a million and said what the introduction fee was." Xu Mang explained: "I can't help it. This guy is getting more and more chicken thieves. It may be that he has lived in the United States for too long and has been infected with some capitalism. Breath."
At this time,
Xiaoman, who had originally frowned, stretched out and smiled at Xu Mang: "I'm coming back for you."
But before Xu Mang could express his admiration, Yang Xiaoman said with a black face: "The death penalty is inevitable, the living sin is inevitable, you can sleep on the sofa tonight!"
Not to mention,
Ever since the sofa was bought, Xu Mang wanted to try the feeling of sleeping on the sofa. Finally, he was constantly dying and had the opportunity to experience the sofa.
Sajia is worth it in this life!
...
The next day,
Xu Mang found brother Chuan Xiao, relying on his relationship, the two temporarily borrowed the office of the Magic City Observatory to study the issues of astrophysics in the movie.
"Fuck!"
"One hundred million times the mass of the sun?" Brother Chuan Xiao almost didn't freak out after hearing this request. What is the concept of a black hole mass of 100 million times... the largest black hole mass in the Milky Way is 4 million times the mass of the sun. One hundred million times...a bit scary.
"Yes."
"This is not the key...it has to exist in this universe in isolation." Xu Mang smiled bitterly: "It is also visually shocking."
in fact,
Xu Mang can do special effects. He triggered this skill before, but now it's not a problem of special effects. He doesn't know what this kind of black hole looks like. There was a real black hole photo before, but it was too blurry.
"Xu Mang?"
"I know that a suspected black hole object is similar to what you want." Brother Chuan Xiao said seriously: "This is an active object, located near Markarian 177. The current evidence shows that this is a black hole that was kicked out. "
Kicked out?
Xu Mang was stunned for a moment. Although the black hole might be kicked out of the existing reasons, no one observed that the black hole was proposed to 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 as much as possible, while taking into account basic astrophysics knowledge, so as not to be searched for.
It took them an hour to complete the black hole in this idea, but it seems that the black hole is too at the moment.
"Or let's cancel Hawking radiation." Xu Mang frowned and said, "Although the existence of Hawking radiation increases the visual impact, according to the plot of the movie, the protagonist has to enter the black hole."
"also."
"But... what about the matter in the surrounding accretion disk?" Brother Chuan Xiao said: "A black hole that exists in isolation, without swallowing other matter, how does this matter explain?"
by,
how could I know!
Xu Mang's face was covered with the word ‘sorrowful reminder’. He really didn’t know how to explain this.
However, it can explain why the matter in the accretion disk is not sucked in. In the journal NaturePhysics, there is an own paper "The Use Value of Quasi-Periodic Oscillation Signals in Black Holes", which describes the existence of a stable orbit near the black hole. .
"Let the screenwriters write this by themselves." Xu Mang said helplessly: "We give them a few choices. First, this black hole swallows one or two medium-sized galaxies, second, this black hole swallows a large number of wandering planets, and third This black hole swallowed the gas cloud."
indeed,
This requires imagination, but Brother Chuan Xiao is quite satisfied with the few guesses Xu Mang made, and the first one is more likely.
"This sucker..." Xu Mang pointed to the sucker filled with a lot of material, frowning, and said: "Is it right... I always feel wrong, Brother Chuan Xiao... we need to do more Many studies must present the most realistic and shocking black hole model."
real...
too difficult!
The previous photo of the black hole was real enough, and it turned out to be burning briquettes.
What the movie wants to express is to stand on the edge of a black hole and see the huge black hole with your own eyes. This is too difficult. At present, many black hole theories are on paper, how can it be true.
Subsequently,
Brother Xu Mang and Chuan Xiao finally understood why this accumulator sucker is a little strange, because the lens of the gravitational field is not considered, the whole black hole looks too smooth, but if the gravitational lens is added, the curvature of the Einstein effect will change. It's impossible to calculate.
Xu Mang turned out the first black hole photo and carefully observed the burning briquettes. This real photo is bright on one side and dim on the other. This is the effect of Doppler shift, so he should also consider it. To Doppler shift. UU reading www.uukanshu.com
but...
This is not shocking enough!
"Xu Mang?"
"Are you still rendering it like this?" Brother Chuan Xiao said helplessly after seeing Xu Mang's black hole model: "Around the horizon...this aperture...how much does it cost to render it?"
"They have money." Xu Mang smiled: "Anyway, I provide the most correct black hole model. The others are not related to me. By the way... the curvature of the accumulating sucker under the gravitational lens. Do you think this is in line with common sense? ?"
Brother Chuan Xiao took a look and said seriously: "There is some exaggeration, you will surely be sprayed to death by the gangsters like this."
