I really don't want to lie down and win

Xu Mang found Brother Chuan Xiao, and with his relationship, the two temporarily borrowed the rooftop office in Shanghai to study issues about astrophysics in the movie.

"Fuck!"

"400 million times the mass of the sun?" Brother Chuan Xiao was almost scared when he heard this request. What is the concept of this black hole mass of [-] million times... The largest black hole mass in the Milky Way is [-] million times the mass of the sun. A billion times... Kind of scary.

"Yes."

"That's not the key... It has to exist in isolation in this universe." Xu Mang smiled wryly, "It also has to be visually stunning."

in fact,

Xu Mang knew how to do special effects. He had triggered this skill before, but now it wasn't a matter of special effects. He didn't even know what this kind of black hole looked like. He had a photo of a real black hole before, but it was too blurry.

"Xu Mang?"

"I do know a suspected black hole celestial body is similar to what you want." Chuan Xiaoxiong said seriously: "This is an active celestial body, located near Markarian 177, the current evidence shows that this is a black hole that was kicked out .”

kick out?

Xu Mang was stunned for a moment. Although there was a possibility of the black hole being kicked out for existing reasons, no one had observed the black hole being pushed out of the galaxy.

In the end, Xu Mang decided to make a model first, and then continuously make corrections on this model, trying to meet the requirements while taking into account the basic common sense of astrophysics, so as not to be approached by bad guys.

It took the two of them an hour to complete the envisioned black hole, but it seems that the black hole is too hard-core.

"Why don't we cancel the 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 is going to enter the black hole."

"also."

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

Depend on,

how could I know!

Xu Mang's face was filled with sadness and reminders, and he really didn't know how to explain these.

However, it can explain why the matter in the accretion disk will not be sucked in. In the journal Nature Physics, there is an article on 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 it themselves." Xu Mang said helplessly, "We gave them a few options. First, the black hole swallowed one or two medium-sized galaxies. Second, the black hole swallowed a large number of wandering planets. Third, This black hole swallows the gas cloud."

indeed,

This required imagination, but Brother Chuan Xiao was quite satisfied with Xu Mang's several guesses, the first of which was more likely.

"This accumulator..." Xu Mang pointed to the accumulator filled with a large amount of matter, frowned, and said, "Aren't you right...I always feel wrong, Brother Chuan Xiao...We need to do more. More research is needed to present the most realistic and shocking black hole model."

reality...

too difficult!

The previous photo of the black hole was real enough, but it turned out to be burning briquettes.

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.

Subsequently,

Brother Xu Mang and Brother Chuan Xiao finally understood why this accumulator is a bit strange, because the whole black hole looks too smooth without the gravitational field lens, but if the gravitational lens is added, it will cause the curvature of the Einstein effect to change. It is impossible to calculate.

Xu Mang dug out the first photo of a black hole and carefully observed the burning briquettes. In this real photo, one side is bright and the other side is dark. This is the effect of Doppler frequency shift, so he should also consider it. to the Doppler shift.

But...

This is not shocking enough!

"Xu Mang?"

"Can others render it like you?" Brother Chuan Xiao said helplessly after seeing Xu Mang's black hole model: "Around the event horizon... this aperture... how much does it cost to render it?"

"They have money." Xu Mang said with a smile, "Anyway, I provide the most correct black hole model, and the others are irrelevant to me. By the way...do you think the curvature of the accumulating disc under the gravitational lens is normal?" ?”

Brother Chuan Xiao glanced at it, and said seriously: "It's a little exaggerated, you will definitely be sprayed to death by the gangsters."

......

Chapter 439 The Most Beautiful Fantasy (2/3)

Xu Mang is not afraid of being stalked by gangsters. He is also a gangster himself, and he is a gangster at all, and the person he gangs up with is his fiancee. Others just use the keyboard to fight online, while Xu Mang is standing in front of him. On the verge of death and the witch bar.

"Hurry up!" Xu Mang said with a smile, "Anyway, I'm in the Physics Department of Fuda University, so they can come and confront me."

"..."

"You are not afraid of death." Brother Chuan Xiao said helplessly: "Have you forgotten how you were destroyed by cyber violence before? And this time it is on a global scale, and you are a scientific researcher yourself, in case your reputation is ruined will be damaged."

Xu Mang said calmly, "It doesn't matter."

Brother Chuan Xiao glanced at Xu Mang: "It's worth living like you, you should eat and drink, and don't take anything to heart."

"Wait a moment!"

"Isn't this a heartless performance?" Xu Mang said angrily, "I'm very upset about the money now, although the gravitational wave detection laboratory is no longer under pressure, but this private research institute is still waiting. With a lot of money, no one came to donate.”

"you say..."

"Many foreign private research universities have so many people donating, why didn't I donate?" Xu Mang sighed: "It's too miserable... If this goes on, it's probably doomed, did we choose the wrong model? Touching the eagle sauce to cross the river, did you touch the wrong place?"

Faced with this problem,

Brother Chuan Xiao, an Internet expert, didn't know how to answer Xu Mang, so he said silently, "There are indeed some difficulties in the early stage, but it's good to get over it, after all, your news hasn't been made public yet."

Too,

At present, others only know the gravitational wave detection laboratory, but they don't know that there is a private research institute next to it. If after winning the Nobel Prize, it uses celebrity influence to raise donations, it is estimated that the fundraising scene will be crowded with people.

but...

It is estimated that some people are starting to move around again.

Until noon,

Yang Xiaoman drove his own car to deliver lunch to Xu Mang and Sun Chuanxiao. Five dishes, one soup, three meat and two vegetables were extremely standard and reasonable. of.

"Fuck!"

"This...this is..." Brother Chuan Xiao said with horror on his face: "Xu Mang...what did you do in your last life? In this life, when you meet a woman like Yang Xiaoman, it was burned by my mother-in-law." The food is unpalatable, I really don't know, I'm shocked."

Yang Xiaoman was almost embarrassed by the praise, and Xu Mang was almost embarrassed when he heard it.
