It took three whole weeks to come up with these contents. Now it seems impossible for Xu Mang and Master Xu to spend a whole day alone, right?

"Master Xu?"

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

"Well?"

"I don't know," Xu Mang said casually. At this time, his mind was full of how to solve the density and temperature problems in front of him.

Thinking about it,

Xu Mang definitely deleted the complexity reasonably and derived a similar concept. Perhaps the hairless law can be used to explain this problem.

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 scope of philosophy and is not within the scope of physics.

Through the hairless law, Xu Mang can derive the concept of proportional expansion in the inflation stage. The energy density will decrease as the volume increases as a whole. The density and volume of cold matter become inversely proportional. The energy density is inversely proportional to the cube of the volume. Radiation

Energy is inversely proportional to the fourth power of volume.

The uniformity, anisotropy, and curvature will decrease, and the number density of strange particles and photons will decrease, eventually approaching a vacuum, symmetrical universe.

Well

That's basically it.

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

Chen Mu, who was treated coldly, only stayed with Xu Mang for three minutes before leaving silently. Xu Mang at work, Master Xu, was too scary. He exuded a depressing temperament, which was autistic.

breath.

Standing next to him, I felt like an idiot.

By noon,

Xu Mang was still obsessed with calculations.

"Master Xu?"

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

"Don't eat!"

"No time!" Xu Mang dropped a sentence and wrote a formula on the blackboard. The probability density of spatial particles is p(x)=ψa(x)^2, and the mean value is x=xψa(x)^2(dx

)

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

What is this?

I can’t understand it no matter how I look at it?

"Master Xu"

"What is this?" Du Yuan asked softly.

"The formula derived from the uncertainty principle calculates the change of energy at any location in space." Xu Mang said expressionlessly: "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 look, and then quickly left the laboratory. Xu Mang was the only one left in Nuo Da's laboratory.

at the same time,

Du Yuan said to his companions: "Damn it, do you know what I just went through?"

"I almost became autistic. It's all my fault. I shouldn't have asked Master Xu questions." Du Yuan sighed and said helplessly: "If I graduate, I'd better go to work."

"Is it so scary?"

"Master Xu is also a human being, not a beast." A student said with a smile: "Speaking of which, Master Xu was writing and drawing on the blackboard all morning. What on earth was he doing?"

Chen Mu said: "Master Xu overturned all our calculations, and then modified some values ​​​​on the original basis. But I am a little confused. These are all calculations based on models. Can Master Xu bypass the step of building a model?

?”

"The devil knows."

"Anyway, I've given up. Even if Master Xu comes, he can't save me." A certain student said with a bitter smile.

laboratory,

Xu Mang sat in front of the blackboard and looked at his calculation process, turning on the sage mode, another special name called daze.

like,

Wrong calculation again.

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

However, this problem does not involve mathematics, but needs to be deduced with the help of a model. In other words, the problem Xu Mang is encountering now is correct from a mathematical perspective, but completely wrong from a physical perspective.

So embarrassing

I can only continue to straighten it out.

In the end, Xu Mang sat down in front of the computer and started to build a new model based on the research of Professor Guan's group. In fact, it was almost the same, but Xu Mang dealt with some details, although he didn't know whether it was correct or not.

"The system turns on beast mode!"

[Beast mode activated]

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

The lunch break was very short for the students. In just the blink of an eye, the members of the research team went to the laboratory one after another.

The first one to arrive was Chen Mu.

"well?"

"Where's Master Xu?" Chen Mu looked around and didn't find Xu Mang. Then he saw the three blackboards and walked a few steps closer to them. They seemed to have been rewritten because there were obviously erasers on them.

traces of the past.

Chen Mu tried to understand the calculation process on the blackboard and some messy formulas, but she soon failed and couldn't understand about two-thirds of the content.

fortunately,

Du Yuan and his gang came to the laboratory.

"Hurry up and take a look, what did Master Xu write?" Chen Mu shouted: "There are three blackboards full."

""

"I said Chen Mu wouldn't be so humiliating." Du Yuan said angrily: "If we can understand Master Xu's calculations, why are we still standing here chatting with you?"

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

moment,

A group of people gathered in front of three blackboards, staring directly at the calculations and formulas on them.
Chapter completed!
