Chapter 306: Overturn and start over (one/three)

"Is there any extra blackboards?" Xu Mang glanced at Du Yuan and asked calmly, "I need three blackboards."
"blackboard?"
"Xu Dashen...what do you want the blackboard for?" Du Yuan asked with a confused look: "If you want to calculate, isn't it another stack of A4 paper?"
"I need to derive the formula to make it easier to view."
"Oh..." Du Yuan nodded. He came from the Department of Mathematics to take charge of the calculations. He quickly understood what Xu Mang wanted to do and hurriedly said, "I will help you move three blackboards."
Words fall,
Du Yuan summoned three male classmates to help Xu Mang move the blackboard together.
The remaining few people looked at Xu Mang with an indifferent expression. They were a little confused and didn't know what he was going to do. Now that it was impossible, what blackboard? What more derivation formula?
"Xu Dashen?"
"You...didn't you say it's impossible?" Chen Mu asked curiously: "Then what are you?"
"Well..."
"I just took a look and felt that there is still a chance to be rescued." Xu Mang said with a smile: "Life always needs hope. If there is no hope, what is the meaning of living?"
"..."
"..."
"..."
Although understand the truth,
But it sounds very twisted,
Does every academic master hide a philosophical heart?
Many people present were quite uncomfortable with Xu Mang's great principles. They had listened to such great principles countless times, but each ended with tragedy. Sometimes the soul chicken soup was a very disgusting product.
quickly,
The three blackboards requested by Xu Mang arrived, and they were placed next to the original blackboard.
Xu Mang immediately began his calculations.
However, after five minutes have passed, Xu Mang is still in a state of confusion. No matter from which angle he explores and thinks, the research results of the group led by Professor Guan can’t find anything wrong in the physical nature. But after a calculation It is simply wrong to happen.
Very strange...
How could this be the case?
The time caliper is also correct. According to the calculation of this model, the time caliper is fixed at greater than e^60. This time just makes the universe flat, uniform and isotropic. Then the time is right...Could it be other problems?
finally,
Xu Mang fixed the problem on the issue of flatness. Although time was enough to make the universe flat, this model did not provide evidence of how flat.
But it took a long time to give up this wrong idea... This is a worldwide problem. It is normal without evidence. If Professor Guan leads the student group to overcome this problem, then he will perform on the spot and explode.
s,
This is the dying rhythm.
"The system...how to do it? Can it give me a breakthrough? I will do the rest."
【Identified by the system, the key point of this problem is exchanged value: 10000 (physical skills)】
[Recognized by the system, the key point of this problem is exchanged value: 10000 (astronomical skills)]
Not expensive,
pay directly!
moment,
Xu Mang suddenly realized that the original problem lies in the problem of quantum fluctuations. In the model of Professor Guan's group, the particle density in each region of the universe during the inflation stage is the same, and the temperature in each region is also the same.
That's it!
Then we must push down this model and start the calculation again.
"Chen Mu!"
"Come here!" Xu Mang shouted at Chen Mu.
Soon Chen Mu came to Xu Mang's side and asked curiously: "Xu Dashen...what's the matter?"
"Tell me the basic parameters of your model." Xu Mang said.
"what?"
"Do you remember Xu Dashen?" Chen Mu said, "Many, many."
"Please delete the word "?" Xu Mang said with a smile: "I am the person with the strongest memory in the country, and there is no one."
"..."
"Oh."
Immediately after,
Chen Mu began to describe the basic parameters of the model to Xu Mang.
Coincidentally,
The phone rang, it was Xiaoman's call. At this point... the call is from Cha Gang, right?
"Hey?"
"What are you doing?" Xu Mang asked curiously, "I'm busy."
"Where?" Yang Xiaoman asked gently: "Are you sitting in Starbucks?"
"Ok..."
"Right!" Xu Mang said with a smile, "Otherwise, where else can I go?"
at this time,
Chen Mu, who was lacking a bit of energy, couldn't help but reminded: "Great God Xu... Am I still reading?"
"..."
"..."
Yang Xiaoman: (￣︿￣)
Xu Mang: (￣△￣;)
The conversation between the two was interrupted for ten seconds.
"Okay!"
"You started to lie to me!" Yang Xiaoman gritted his teeth and said, "Where are you now? Who is the girl next to him?"
"Xiaoman, listen to me explain...actually this..."
Xu Mang was halfway through the explanation and was interrupted by Chen Mu again.
"Xu Dashen?"
"Are we going to start?" Chen Mu asked.
"Ha ha!"
"Do you think I am not gentle enough?" Yang Xiaoman sneered: "If you have the ability, don't hold me tonight."
"Ouch..."
"Not what you think...actually..."
"roll!"
Snapped,
Xiaoman hung up.
Xu Mang looked at the interface where the call was interrupted, and his back felt a little cold. It seemed that tonight was a sleepless night...this woman is probably going crazy.
"let's start..."
"Speak a little faster." Xu Mang put away his phone and said to Chen Mu with a deadly face.
"Oh..."
ten minutes later,
Xu Mang basically mastered all the information, and immediately began to re-advertise the model.
Chen Mu stood by and looked at Xu Mang with a confused expression. He didn't know what he was going to do. He just understood that he was calculating. As the most talented student in the whole group, he figured out Xu Mang's behavior two minutes later.
This...
Is this the whole process overturned and recalculated? But is time too late?
It took three full weeks for these contents to come out. Now Xu Mang Xu is alone, and then spend a day... It seems impossible, right?
"Xu Dashen?"
"Are you coming tomorrow?" Chen Mu asked.
"Uh?"
"I don't know..." Xu Mang said casually. At this time, he was full of ideas about how to solve the density and temperature problems in front of him.
Thinking about going,
Xu Mang absolutely cut down the complexity reasonably and derives a similar concept, perhaps using the law of hairlessness to explain this problem.
In fact, the universe horizon is similar to the black hole horizon. The only difference is what exists at the other end of the horizon. Of course, this belongs to the category of philosophy and is not within the scope of physics.
According to the law of hairlessness, Xu Mang can derive the concept of proportional expansion in the inflation phase. The energy density as a whole will decrease as the volume increases. The density and volume of the cold matter become inversely proportional, and the energy density is inversely proportional to the cube of the volume. Energy is inversely proportional to the fourth power of volume.
Uniformity, anisotropy, and curvature will decrease, and the number density of strange particles and photons will decrease... eventually approaching a vacuum and symmetrical universe.
Uh ...
Basically that's it.
Based on these concepts, Xu Mang began to modify some basic parameters in the expansion model set by Professor Guan. This is a purely mathematical calculation.
Chen Mu, who was treated cold, just stayed with Xu Mang for three minutes, and then left silently. Xu Mang at work, Xu Dashen was too terrible, and he exuded a depressive temperament...No, it was a kind of intimidation. Autistic breath.
Standing beside him, I felt like an idiot.
Until noon,
Xu Mang is still obsessed with calculating.
"Xu Dashen?"
"It's noon...it's time to go for dinner." Du Yuan said cautiously.
"Don't eat!"
"No time!" Xu Mang dropped a sentence and wrote the formula on the blackboard. The probability density of space particles is p(x)=
ψa(x)
^2, and the average value is x=x
ψa(x)
^2(dx)...
Du Yuan was taken aback for a moment, looking at the stuff on Xu Mang's blackboard, with the word Confused on his face.
What is this?
Can't read it at all?
"Xu Dashen..."
"What is this?" Du Yuan asked quietly.
"The formula derived from the uncertainty principle calculates the change of energy at any position in space." Xu Mang said blankly: "This change violates the law of conservation of energy, but it occurs anywhere in space and the change time is very short. , Observed on the cosmic caliper, the law of conservation of energy still holds."
"sorry..."
"excuse me."
Du Yuan said sorry to Xu Mang with an apologetic expression, and then flew out of the laboratory, leaving Xu Mang alone in the laboratory of Nuo University.
at the same time,
Du Yuan said to his companions: "Fuck... do you know what I just experienced?"
"I'm so... I almost closed up. I blame my bad mouth. I shouldn't ask Dashen Xu a question." Du Yuan sighed and said helplessly: "If I graduate...I'll go to work. "
"Is it so scary?"
"Xu Dashen is also a human being, not a beast." A student said with a smile: "Say, what is Xu Dashen doing writing and drawing on the blackboard all morning?"
Chen Mu said: "Xu Dashen overturned all of our calculations, and then modified some values ​​on the original basis... But I am a little puzzled. These are all calculations derived from models. Xu Dashen can bypass the model building. One step?"
"The ghost knows."
"Anyway, I gave up... even if Xu Dashen came, I couldn't save me." A student smiled bitterly.
...
laboratory,
Xu Mang sat in front of the blackboard and watched his calculation process, and activated the sage mode, with another special name called Daze.
like,
It was wrong again.
Xu Mang was already confused. After solving the symmetry problem, he discovered that a new problem had appeared.
However, this problem does not involve mathematics, but needs to be deduced with the help of models. That is to say, Xu Mang's current problems are correct to calculate from a mathematical point of view, but from a physical point of view, it is completely wrong.
so awkward...
Can only continue to chant.
Finally, Xu Mang sat honestly in front of the computer and began to build a new model based on the research of Professor Guan's group. In fact, they were almost the same, but Xu Mang processed some details, although I don't know if this is right.
"System... Turn on the beast mode!"
[Activate the beast mode]
Xu Mang accelerated the progress of the model building, after all, time is money.
...
The noon break was very short-lived to the students. It was just a blink of an eye. The members of the research team went to the laboratory one after another.
Chen Mu was the first to arrive.
"Ugh?"
"Where's Xu Dashen?" Chen Mu looked around and didn't find Xu Mang's figure. After that, he saw the three blackboards and walked a few steps to reach him, as if he had been rewritten because there was obviously an eraser. Traces of the past.
Chen Mu tried to understand the calculation process on the blackboard ~EbookFREE.me~ and some messy formulas, but she soon failed, and probably two-thirds of the content could not be understood.
fortunately,
Du Yuan and his gang came to the laboratory.
"Hurry up and take a look. What did Xu Dashen write?" Chen Mu shouted, "Three blackboards full."
"..."
"I said Chen Mu... don't bring such humiliation." Du Yuan said grimly: "If we can understand Xu Dashen's calculations, still stand here and chat with you?"
"Since you don't understand, let's analyze and analyze together." Chen Mu said, "Hurry up!"
moment,
A group of people gathered around the three blackboards, staring straight at the calculations and formulas on them.
Then... everyone is autistic.
