Chapter 439: The most wonderful fantasy (two/three)

Xu Mang is not afraid of being used by the gangsters. He is also a gangbanger himself, and he is also a gangbanger. The object of his is his fiancée. Others just use the keyboard to use the Internet, while Xu Mang is standing. The edge of death talked to the witch.
"Furry up!" Xu Mang said with a smile, "Anyway, I'm in the Physics Department of Fuda. They can come to confront me."
"..."
"You are also not afraid of death." Brother Chuan Xiao said helplessly: "Forgot to be destroyed by cyber violence before? And this time it is global, plus you are a scientific researcher, in case your reputation rises. Will be harmed."
Xu Mang said calmly: "It doesn't matter."
Brother Chuan Xiao glanced at Xu Mang: "It's worth living like you. You should eat, drink, and don't worry about anything."
"Wait!"
"Isn't this a kind of heartless performance?" Xu Mang said grimly, "I am very upset for the money now, don't look at 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 the donation."
"You said..."
"Many foreign private research universities have so many donations, why didn't they donate to me?" Xu Mang sighed, "It's too miserable... I guess it will be over if this continues. Did we choose the wrong model? Cross the river by touching the eagle sauce, touching the wrong place?"
Faced with this problem,
Internet expert Chuan Xiaoxiong didn't know how to answer Xu Mang, and said silently: "There are indeed some difficulties in the early stage, but it will be fine if you get through it. After all, your news has not been made public."
Too,
At present, others only know about the gravitational wave detection laboratory, but they don't know that there is a private research institute nearby. If you get the Nobel Prize and use the celebrity effect to raise donations, it is estimated that the fundraising scene will be crowded.
but...
It is estimated that some people are starting to move around again.
Until noon,
Yang Xiaoman drove his car and gave Xu Mang and Sun Chuanxiao lunch. Five dishes, one soup, three meats and two vegetarian dishes. The standards were very reasonable. However, in front of outsiders, Yang Xiaoman brazenly said buying outside as his own. of.
"Fuck!"
"This...this is..." Brother Chuan Xiao said with a horrified face: "Xu Mang...what did you do in your last life? When you met a woman like Yang Xiaoman in this life, my wife burned it. The food is terrible. It's really not better than not knowing it. It's a shock."
Yang Xiaoman was almost ashamed of being praised, and Xu Mang was almost ashamed of hearing it.
quickly,
Xiaoman cleared the table and left the office with a bunch of lunch boxes. Looking at the leaving back, Xu Mang didn't know what to say for a while, she gradually moved towards the image of Mrs. Xu subtly.
in the afternoon,
Brother Xu Mang and Chuan Xiao also conducted a series of investigations and discussions on this black hole. The question now is how to distinguish between the black hole’s horizon and the horizon. According to Xu Mang’s idea, add a new item at the edge of the horizon. As the bright band.
However, this idea was rejected by Brother Chuan Xiao. Judging from the real black hole photo, there is no so-called bright band.
In order to clarify this problem,
Xu Mang and Chuan Xiao brothers conducted a lot of research work, and finally figured out the basic situation of the bright band. The accretion disk of the black hole on the photo is very thick in physics, but it is very thin in optics. Radiation can basically pass through without hindrance.
When designing a black hole in a movie, the opposite structure can be adopted. The accretion disk is physically very thin, but optically very thick, and radiation cannot pass through it. This solves this problem.
of course,
A lot of everything is just staying in thoughts and computers, and real examples are needed for reference, a black hole with a mass equivalent to 100 million times the sun.
Brother Xu Mang and Chuan Xiao looked at M31, the Andromeda galaxy about 2.54 million light-years away from Earth.
According to the detection of astronomers, there is a supermassive black hole in the Andromeda galaxy. Its mass reaches 100 million times the mass of the sun, which basically meets the requirements of the movie, but it only meets the quality standard.
Research on the data of this hole in Andromeda finally determined the type of black hole in the movie, in short, moved it intact.
"Brother Chuanxiao?"
"Since black holes can affect time, then... if a person stands on the edge of a black hole for a year, how should he calculate the time after he returns to Earth?" Xu Mang asked with a grin.
"..."
"This...I really don't know, maybe the Milky Way is gone." Brother Chuan Xiao smiled.
"In fact, this script is pretty good."
"I guess I have found a scientific worker to assume the role of scientific consultant." Xu Mang said seriously: "The universe is divided into two independent time and space, outside the horizon and inside the horizon. I have no objection to this."
"Moreover, when you are close to the horizon, you don’t have to doubt...it must be slower than on earth time. How much slower depends on the screenwriter’s own ability to make up." Xu Mang said seriously: "But the time inside the black hole, The science consultant has a problem with his fantasy ability. The time dilation effect should not be used, but the time visual effect should be used."
Visual effect?
This...
Is there this concept?
Brother Chuan Xiao looked confused. It was the first time he heard the visual effect of this time.
Immediately after,
Brother Chuan Xiao heard the most absurd things in life. In Xu Mang's fantasy black hole, time can be observed, that is, you can see the past, present, and future, and even use gravity to change the future.
According to Xu Mang's meaning, anyway, everyone can't understand the definition of black hole time, so they go straight to boldly imagine.
However, according to the general theory of relativity, a time is selected to enter the black hole, and this time can only be the corresponding time point after entering the horizon. This is to prevent the grandmother paradox from appearing.
So as not to let the time go wrong.
"Xu Mang?"
"Yes!" Brother Chuan Xiao smiled: "Your science fiction ability is very strong!"
Xu Mang smiled and said indifferently: "Actually, we are all nonsense. Both you and I know that there is only one death in the black hole. It is better to imagine the inside of this black hole a bit more beautiful."
"Then how to shuttle?"
"..."
Xu Mang's spirit of pretending to be flaming just now was wiped out by Brother Chuan Xiao in a moment.
"It's all to this point... I just forced a wormhole. Anyway, it's a science fiction movie... The screenwriter will try his best to rationalize it." Xu Mang smiled: "And I looked at the previous plot, there are also About using wormholes to travel through time and space."
"Furthermore, the definition given by Einstein is instantaneous space transfer or time travel." Xu Mang said seriously: "This matter does not need to be discussed, listen to me!"
Brother Chuan Xiao was taken aback, and asked curiously: "Are you watching "Boss Huang Restaurant" recently?"
"How do you know?" Xu Mang was stunned: "Xiao Man looked crazy recently... I was forced to watch with her."
"My wife is too, leading me to watch it too."
"..."
"..."
The same is the end of the world, why do you know each other before.
Horrible!
Regarding this black hole problem, the two have solved half of it, and the other seems to be not a big problem, but it was already 4:30 in the afternoon, and the two had cleaned up and prepared to go home for dinner.
"Xu Mang..."
"You are much happier than me." Brother Chuan Xiao sighed and complained to Xu Mang: "I can only eat the egg fried rice made by my wife when I go home. What about you... it's a warm meal."
Seeing the back of Brother Chuan Xiao going away, Xu Mang's heart is mixed, brother...the egg fried rice is at least hot!
Fuda,
Teacher apartment.
Xu Mang sat at the table, watching two sandwiches with only lettuce on the plate, and a glass of freshly squeezed orange juice on the side. He reached out and touched the sandwich... it's hot!
Looking up at the pile of fruit and vegetable salads in Xiaoman's bowl, I felt that this kind of life seemed familiar to me, did my mother come back?
"Don't look at me..."
"This is all ordered by my mother-in-law." Yang Xiaoman knew what Xu Mang wanted to say, and said helplessly: "My mother-in-law called me a few days ago to let me pay attention to your healthy diet and eat more fruits and vegetables , Eat as little meat as possible."
Words fall,
Yang Xiaoman turned on the phone and replayed what Xu's mother had said on WeChat.
"Xiao Manna, you and Xu Mang usually eat more fruits and vegetables, less takeaway. Vegetables are healthy for your body, and you must put less salt. If you are oily, try to use extra virgin olive oil. Mom later. I'm sending you two articles about health preservation, you read them carefully."
at this time,
Neither Xu Mang nor Xiaoman spoke, and sat quietly at the table, looking at each other.
"Go for hot pot?" Xu Mang suggested: "Choose the spicy butter pot bottom."
"go!"
...
The next day,
After Xu Mang finished the class for the students, he came to the Magic City Observatory and began to study the black hole more carefully, such as simulating the basic structure of the black hole, or observing the black hole from a certain perspective. There are other problems.
Until three o'clock in the afternoon,
The two basically solved all the problems of the black hole. Among them, Xu Mang knew the concept of the so-called five-dimensional space. In Randall’s words, the five-dimensional space is a four-dimensional hypercube. From a geometric point of view, it is the three-dimensional world. The behavior of the cube in the four-dimensional world is like a cube relative to a square.
In the five dimensions, you can see a person's different life trajectories, but superimposed together and projected in a thinking space, the probability wave collapses into a specific state, which is a certain life experience of his.
This is exactly the same as the inside of the black hole imagined by Xu Mang.
Xu Mang then sent this plan to Nolan's brother.
at the same time,
new York,
Later in the night.
Great director Nolan’s brother Jonathan Nolan is revising his movie script. He and his brother are making a movie together. As the screenwriter of this movie, he is the most serious one.
With his brother’s pursuit of truthfulness, Jonathan Nolan invited two fairly well-known experts as scientific consultants to co-create the script for this movie. So far, everything is pretty good~EbookFREE.me ~But... there are some details that need to be modified.
Especially the issue of black holes.
My brother felt that this was not shocking enough, and finally contacted the authority in the field of black holes in desperation. Professor Xu Mangxu came to solve this problem. Of course... it was not known by the two scientific consultants.
At this time,
Jonathan Nolan noticed an email from his mailbox and clicked it to see that Xu Mang had sent it.
"This..."
"So fast?!" Jonathan Nolan looked at the content, and he was a little surprised. It took two scientific consultants a week, but Xu Mang took less than two days. Is there a quality problem?
