Analyze the Sonoluminescence Phenomenon

Lv Yongchang shook his head slowly.

"If the sun is affected by unknown human factors, it would fit all the laws."

Qiu Tianzhong paused, standing in place with a vacant gaze at Lv Yongchang: "Then... what kind of thing can affect the sun?"

Lv Yongchang shook his head again: "I'm not clear."

He was telling the truth.

Even in the previous life, humanity had not found the reason for the sun's mutation.

Of course, this was also related to the time humans discovered the mutation.

In the previous life, humans did not have much time to study the cause of the sun's mutation, and all resources were arranged for the underground city and starship plan.

Even now, as the time node of the sun's mutation has changed, Lv Yongchang has a vague guess in his heart.

Perhaps, the mutation of the sun is man-made! 

Of course, this so-called man-made is definitely not done by Earth civilization.

But due to lack of evidence, he can't casually say his guess.

Perhaps Lv Yongchang's words gave Academician Qiu Tianzhong some hope, and his face gradually eased a bit.

"...Then, what should we do now?"

Qiu Tianzhong is not a fool.

Since this matter can be discussed openly in the Xia National Hall, it naturally shows its reliability.

The leaders of Xia will never make such a low-level mistake! 

Qiu Tianzhong's question also reminds everyone present.

Since the situation is irreversible, solutions are what really need to be considered! 

Seeing everyone's gaze turn to himself again, Lv Yongchang's tense expression on his face also relaxed a bit.

He gently clicked and dragged the mouse to open a PPT again.

"As I said before, what Xia needs to complete first is the Moon Palace plan."

"Of course, according to Xia's current... or human technology level, it is impossible to achieve the Moon Palace plan."

Saying that, Lv Yongchang shrugged helplessly.

The faces of the academicians and professors present slightly darkened.

The words are correct.

So far, only a few astronauts who participated in the U.S. Apollo program decades ago have truly landed on the moon.

And Xia... although it has carried out lunar exploration plans, it is still far from manned lunar landing.

"Therefore, the urgent task at hand is to climb the technology tree."

Lv Yongchang said while clicking the mouse.

The projector light flickered slightly, and three technology names slowly appeared on the screen.

"Fusion reactor miniaturization technology" 

"Electric propulsion technology" 

"Aerospace plane technology" 

...

After the meeting, Lv Yongchang did not stop and went directly to the Daxia Bay Nuclear Physics Laboratory.

At this time, the surroundings of Daxia Bay Nuclear Physics Laboratory have already started construction.

According to Councilman Li's plan, Daxia Bay Nuclear Physics Laboratory will be expanded to ten times its original size! 

After the expansion, the laboratory will be renamed Xia's No. 1 laboratory.

And the primary task of Xia's No. 1 laboratory is to lead all Xia people into space! 

...

Daxia Bay Nuclear Physics Laboratory... No, Xia's No. 1 laboratory.

Lv Yongchang looked solemnly at the transparent container filled with water in the center of the test bench.

This is a container made by the laboratory in a few days, responsible for conducting acoustic luminescence experiments.

"Yongchang, are you sure that acoustic luminescence is related to nuclear fusion?"

Fang Xu looked at Lv Yongchang nervously and asked in a low voice.

This thing... To be honest, he doesn't feel very reliable when he looks at it.

Lv Yongchang nodded slightly: "I'm sure!" 

Fang Xu's eyes brightened slightly: "Oh?! How are you sure?"

"Did you see any papers?"

Lv Yongchang glanced at Fang Xu and threw out five words: "Based on my intuition!" 

Fang Xu: "..."

"Let's start the experiment!" Lv Yongchang didn't explain too much to Fang Xu and directly said to the researcher in charge of operation.

The next moment, the ultrasonic device under the transparent container started to work.

The water surface inside the transparent container instantly rippled slightly.

Lv Yongchang's gaze was fixed on the monitoring data next to him.

When he saw that the ultrasonic vibration frequency displayed on the computer screen reached the target value, a flash of light appeared in his eyes instantly.

"Quick! Inject gas!" 

The researcher next to him swallowed slightly and hurriedly pressed the button on the console.

A series of fine bubbles appeared at the bottom of the transparent container.

Under the action of buoyancy, bubbles slowly rose.

A magical phenomenon occurred! 

Under the action of ultrasonic waves, bubbles vibrated back and forth in the liquid.

The next moment, when the bubble shrank to its smallest volume, a faint light was released from it! 

"It worked!" 

A trace of excitement flashed through Lv Yongchang's eyes.

Then, he suddenly turned his head and looked at the researcher next to him: "Have all the data been recorded?!" 

The researcher quickly typed on the keyboard and then let out a breath.

"Professor, all data has been successfully recorded!" 

"Good!" Joy grew stronger in Lv Yongchang's eyes. "Send all experimental data to my computer."

"Next, I need to 'seclude' for a period of time, don't disturb me!" 

"By the way, brother Xu, continue to conduct experiments with different solutions and different frequencies of ultrasonic waves. I need more data!" 

With that, Lv Yongchang strode towards his office! 

...

Inside the office.

Lv Yongchang frowned tightly as he looked at the dense and messy data on his computer.

The temperature during bubble collapse in that acoustic luminescence phenomenon was not very high.

Only about 100,000 degrees Celsius.

For controllable nuclear fusion that easily reaches hundreds of millions of degrees Celsius, 100,000 degrees Celsius... It's not even worth mentioning! 

If he wants to achieve controllable nuclear fusion through acoustic luminescence, he must first solve the upper limit problem of bubble collapse temperature! 

After all, he needs to make the temperature inside the bubble reach the basic temperature for nuclear fusion, right?

And the most direct way to solve this problem is to establish a mathematical model! 

As for factors affecting bubble collapse temperature...

It's no exaggeration to say that Lv Yongchang can make the most basic inference with his toes.

It's nothing more than ultrasonic frequency, solution type, or container shape.

This is also why he specifically instructed Fang Xu before secluding himself.

Any mathematical model requires a large amount of experimental data support! 

Looking at various data continuously appearing on his computer, Lv Yongchang took a deep breath.

Then he reached for the pen beside him.

"Pu Er~" 

The sound of pulling out a pen cap is clear and loud.

The next moment, his eyes changed instantly.

The moment of intense work began! 

The quiet office was suddenly filled with the rustling sound of pen tips rubbing against manuscript paper!
