Chapter 306: Tear Down and Start Over (1/3)

"Are there any extra blackboards?" Xu Mang glanced at Du Yuan and asked indifferently, "I need three blackboards." ”

"Blackboard?"

"Great God Xu... What do you want the blackboard for?" Du Yuan asked with a confused expression, "If you want to calculate, isn't it another stack of A4 paper?"

"I need to derive the formula so I can see it. ”

"Oh..."Du Yuan nodded, he was in charge of the calculation from the Department of Mathematics, and quickly understood what Xu Mang wanted to do, and hurriedly said, "I'll help you move three blackboards." ”

Words fall,

Du Yuan gathered three male classmates to help Xu Mang move the blackboard.

The rest of the people, looking at Xu Mang with an indifferent face, were a little confused and didn't know what he was going to do, since it was determined that it was impossible, what blackboard do they need? What more do you need to derive the formula?

"Great God Xu?"

"You... Didn't you say it was impossible?" Chen Mu asked curiously, "Then what are you?"

"Well..."

"I just looked at it and felt that there was still a chance to save it. Xu Mang said with a smile: "Life always needs hope, if there is no hope, what is the point of living?"

β€œ...”

β€œ...”

β€œ...”

Although the truth is understood,

But it sounds very twisted,

Does every top student hide a philosophical heart?

Many people present were quite uncomfortable with Xu Mang's truth, they had heard this kind of truth countless times, but every time it ended in tragedy, sometimes chicken soup for the soul was a very disgusting product.

soon

The three blackboards that Xu Mang asked for arrived, and they were placed next to the original blackboards.

Immediately, Xu Mang began his own calculations.

However, after a full five minutes, Xu Mang was still in a state of confusion, no matter from which angle to explore and think, the research results of the group led by Professor Guan could not find any fault in their physical properties at all, but it was not right at all when the calculation happened.

It's weird...

How could this be the case?

The time caliper is also correct, according to the calculation of the time caliper of this model 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 something else?

ultimately

Xu Mang fixed the problem on flatness, and although there was enough time to make the universe flat, this model did not provide evidence of how to flatten.

But after a long time, I gave up this wrong idea... This is a worldwide problem, and it is normal to have no evidence, and if Professor Guan leads a group of students to overcome this problem, then he will perform an explosion on the spot.

I don't understand, I don't understand

It's the rhythm of death.

"The system... What should I do? Can you give me a breakthrough? I'll do the rest. ”

[Identified by the system, the exchange value of the key point of this problem: 10000 (physical skill)]

[Identified by the system, the exchange value of the key point of this problem: 10000 (astronomical skill)]

Not expensive,

Pay Directly!

moment

In the model of Professor Guan's group, the particle density of each region of the universe in the inflation phase is the same, and the temperature of each region is also the same.

I see!

Then you have to knock the model down 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, "Great God Xu... Is there something going on?"

"Tell me about the basic parameters of your model. Xu Mang said.

"Huh?"

"Xu Dashen, do you remember?" Chen Mu said: "Many, many of them." ”

"Please remove the word '?'. Xu Mang said with a smile: "I am the person with the strongest memory in the country, and there is no one." ”

β€œ...”

"Oh. ”

Followed by

Chen Mu began to describe the basic parameters of the model to Xu Mang.

fortunately

The phone rang, it was a call from Xiao Man, this point... When I called, I guess it was a check, right?

"Hello?"

"What are you doing?" Xu Mang asked curiously, "I'm busy." ”

"Where?" Yang Xiaoman asked softly, "Are you sitting at Starbucks?"

"Hmm..."

"That's right!" Xu Mang said with a smile, "Otherwise, where else can I go?"

At this point,

Chen Mu, who was missing a piece of strength, couldn't help but remind: "Great God Xu... Am I still reading it?"

β€œ...”

β€œ...”

Yang Xiaoman: (* Μ„γ€ˆ Μ„)

Xu Mang:( Μ„β–³ Μ„;)

The call between the two was interrupted for a full ten seconds.

"Okay!"

"You're starting to lie to me!" Yang Xiaoman gritted his teeth and said, "Where are you now? Who is the girl on the side?"

"Xiao Man, listen to my explanation... Actually, this..."

Xu Mang was halfway through his explanation and was interrupted by Chen Mu again.

"Great God Xu?"

"Do we still want to start?" asked Chen Mu.

"Huh!"

"Do you think I'm not gentle enough?" Yang Xiaoman sneered: "If you have the ability, don't hug my mother tonight." ”

"Oops..."

"It's not what you think... Actually..."

"Get out!"

syllable

was hung up by Xiao Man.

Xu Mang looked at the interface that interrupted the call, and his back felt a little cold, it seems that tonight is a sleepless night... This woman is probably going crazy.

"Let's get started..."

"Speak a little faster. Xu Mang put away his mobile phone and said to Chen Mu like a dead face.

"Oh..."

Ten minutes later,

Xu Mang basically had all the information, and then began to re-channel the model.

Chen Mu stood on the side and looked at Xu Mang with a confused expression, he didn't know what he was going to do at all, but he understood that he was calculating, as the most talented student in the entire group, he figured out Xu Mang's behavior after two minutes.

This...

Is it a recalculation of the whole process? But is there time to do it?

It took three weeks to get these things out, and now it's just Xu Dashen alone, and then it will take a day... Seems unlikely, right?

"Great God Xu?"

"Are you coming again tomorrow?" asked Chen Mu.

"Huh?"

"I don't know..."Xu Mang said nonchalantly, at this time he was full of thoughts on how to solve the density and temperature problem in front of him.

Thinking about it,

Xu Mang definitely cut out the complexity reasonably, and deduced a similar concept, which may be explained by the law of no hair.

In fact, the cosmic horizon is similar to the black hole horizon, the only difference is what exists on the other side of the horizon, of course, this belongs to the philosophical category, not within the scope of physics.

Through the law of glars, Xu Mang can derive the concept of proportional expansion in the skyrocketing stage, the energy density will decrease with the increase of volume, the density and volume of cold matter become inversely proportional, the energy density is inversely proportional to the cubic of the volume, and the radiant energy is inversely proportional to the fourth power of the volume.

Uniformity, anisogeneity, curvature decreases, singular particles and photon number density decreases... Finally approaching a vacuum, symmetrical universe.

Belch...

That's basically it.

Based on these concepts, Xu Mang began to modify some basic parameters in the expansion model set by Professor Guan, which is a purely mathematical calculation.

Chen Mu, who was treated coldly, only stayed by Xu Mang's side for three minutes, and then left silently, Xu Mang's great god at work was too terrible, and he exuded a depressed temperament... No, it's an autistic atmosphere.

Standing next to him, I felt like an idiot.

By noon,

Xu Mang is still obsessed with calculations.

"Great God Xu?"

"It's noon... It's time to go eat. Du Yuan said cautiously.

"Don't eat it!"

"No time!" Xu Mang dropped a sentence, writing the equation on the blackboard, the probability density of space particles is p(x)=|ψa(x)|^2, and the mean value is x=x|ψa(x)|^2(dx)...

Du Yuan was stunned for a moment, looking at the things on Xu Mang's blackboard, and the word confusion was written on his face.

What's this?

Can't understand how to look at it?

"Great God Xu..."

"What is this?" Du Yuan asked in a low voice.

"A formula derived from the uncertainty principle that calculates the change in energy at any point in space. Xu Mang said expressionlessly: "This kind of change violates the law of conservation of energy, but it occurs anywhere in space, and the change time is very short. ”

"I'm sorry..."

"Excuse me. ”

Du Yuan said sorry to Xu Mang with an apologetic face, and then left the laboratory in a hurry, leaving Xu Mang alone in the laboratory of Nuoda.

meanwhile

Du Yuan said to his companions: "... Do you know what I've just been through?"

"What the hell... I almost shut myself up, I blame my mouth, I shouldn't ask Xu Dashen questions. Du Yuan sighed and said helplessly: "If you graduate... I'd better go to work. ”

"Is it so scary?"

"Xu Dashen is also a human, and he is not a beast. A certain student said with a smile: "Anyway, Xu Dashen wrote and drew on the blackboard one morning, what is he doing?"

Chen Mu said: "Xu Dashen overturned all our calculations, and then modified some values on the original basis... But I'm a little puzzled, these are all calculations made by models, can Xu Dashen bypass the step of building a model?"

"Hell knows. ”

"I'm dead set on anyway... Even if Xu Dashen comes, he can't save me. One of the students smiled wryly.

...

laboratory

Xu Mang sat in front of the blackboard and watched his calculation process, and turned on the sage mode, another special name is called Daze.

It seems like

Miscalculated again.

Xu Mang was already confused, and after solving the symmetry problem, he found that a new problem had arisen.

However, this problem does not involve mathematics, but needs to be derived with the help of models, which means that the problem Xu Mang is encountering now is correct from a mathematical point of view, but from a physical point of view, it is a mess.

It's embarrassing...

You can only continue to rectify.

In the end, Xu Mang sat down in front of the computer honestly and began to build a new model based on the research of Professor Guan's group, which was actually similar, but Xu Mang processed some details, although I don't know if this is right.

"The system... Turn on Beast Mode!"

【Beast Mode Activation】

Xu Mang accelerated the progress of building the model, after all, time is money.

...

During the lunch break, the students were very brief, just a blink of an eye, and the members of the research team went to the laboratory one after another.

The first to arrive was Chen Mu.

"Huh?"

"What about Xu Dashen?" Chen Mu looked around, but did not find Xu Mang's figure, and then saw the three blackboards, walked a few steps and came to him, as if they had been rewritten, because there were obvious traces of erases.

Chen Mu tried to understand the calculation process on the blackboard, as well as some messy formulas, but she soon failed, and about two-thirds of the content could not be understood.

fortunately

Du Yuan and his group came to the laboratory.

"Hurry up and take a look, what did Xu Dashen write?" Chen Mu shouted: "Three blackboards are full." ”

β€œ...”

"I said Chen Mu... Don't bring such humiliation. Du Yuan said angrily: "If we can understand Xu Dashen's calculations, still standing here and chatting with you?"

"Since you can't understand it, let's analyze and analyze it together. Chen Mu said: "Hurry up!"

moment

A group of people gathered in front of three blackboards, staring at the equations and formulas on them.

And then... Everyone is autistic.
