Chapter 438 Difficulties (1/3)(2/2)
"That's not the key. It has to exist in isolation in this universe." Xu Mang said with a wry smile: "It also has to be visually stunning."
actually,
Xu Mang knows how to do special effects. He has triggered this skill before, but now it is not a problem with the special effects. He himself does not know what this kind of black hole looks like. He had a photo of a real black hole before, but it was too blurry.
"Xu Mang?"
"I do know that a suspected black hole object is similar to what you want." Brother Chuanxiao 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.
"
Kick out?
Xu Mang was stunned for a moment. Although there are existing reasons for the possibility of the black hole being kicked out, no one has observed the black hole being kicked 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 basic astrophysical knowledge to avoid being approached by the gangsters.
It took the two of them an hour to complete the imaginary black hole, but it seems that this black hole is too hard-core at the moment.
"How about we 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 inside of the black hole."
"Alright."
"But what about the material in the surrounding accretion disk?" Brother Chuanxiao said: "For an isolated black hole, how can these materials be explained without swallowing other materials?"
Depend on,
How do I know!
The word 'tragic' was written all over Xu Mang's face, 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. There is a paper of its own in the journal "Naturephysis" "The Utilization Value of Quasi-periodic Oscillation Signals in Black Holes", which describes the existence of a stable orbit near the black hole.
.
"Let the screenwriters make up this themselves." Xu Mang said helplessly: "We gave them several choices. First, the black hole swallowed one or two medium-sized galaxies. Second, the black hole swallowed a large number of wandering planets. Third, the black hole swallowed a large number of wandering planets.
The black hole swallowed the gas cloud."
indeed,
This requires imagination, but Brother Chuan Xiao is quite satisfied with the several guesses Xu Mang made, the first of which is more likely.
"This accumulation sucker." Xu Mang pointed to the accumulation sucker filled with a large amount of matter, frowned, and said, "Is that right? I always feel that I am wrong. Brother Chuan Xiao, we need to do more research to present the most realistic representation."
and stunning black hole models.”
reality
It’s so difficult!
The previous photo of the black hole was real enough, but it turned out to be just 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 theories about black holes are only on paper. How can it be true?
Subsequently,
Xu Mang and Brother Chuan Xiao finally figured out why this accumulation sucker was a bit strange. Because the lens without considering the gravitational field, the entire black hole looked too smooth. However, if a gravitational lens was added, the curvature of the Einstein effect would change.
It's impossible to calculate.
Xu Mang pulled out the first black hole photo and carefully observed the burning briquettes. This real photo has one side bright and one side dim. This is the effect of Doppler frequency shift, so he should also consider it.
to 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: "How much does it cost to render the aperture around the event horizon?"
"They have money." Xu Mang said with a smile: "Anyway, I provide the most correct black hole model, and the rest is irrelevant to me. By the way, the curvature of the sucker under the gravitational lens, do you think this is consistent with common sense?"
