On the phone, Xu You expressed his thoughts to Xu Zhou.

Because the distance between the blue star and the moon is 38 kilometers, there will be some delays in the transmission of information.

Fortunately, this will not have much impact on the conversation between the two.

After listening to Xu You's thoughts, Xu Zhou nodded and said:

"I understand what you mean, but this is indeed a very difficult problem to solve. The materials used to make space elevators must meet the conditions of high strength and low density at the same time, in order to cope with the strong gravitational and centrifugal forces. This material, Only carbon nanotubes fit the bill."

Based on his years of research and conclusions, Xu Zhou quickly made suggestions to Xu You.

In fact, Xu You is also prepared for this direction, but Xu You knows that with the current research on carbon nanotubes in Blue Star, it should be impossible to make a space elevator from Blue Star to the moon.

Thinking of this, Xu You continued to ask Xu Zhou:
"Dad, with the current Blue Star technology, how high can a space elevator be made with the carbon nanotubes produced?"

Xu Zhou thought for a while and said:

"With the current level of technology of Blue Star, it is not a problem to manufacture a space elevator of tens of thousands of kilometers. Such a space elevator is mainly used for transportation between Blue Star and the space station. But if you want to go to the moon If so, it is absolutely impossible.”

At the beginning of the appointment, a large number of netizens filled out the application for going to the moon to participate in the lunar underground shelter experience activities.

Xu You didn't delay the progress of the experiment because of this, because all the experiments in Jijing University's laboratory were going on all the time, and he would report the latest progress to Xu You at any time.

Even after the experience time is over, many people are still unsatisfied and want to extend the experience time again.

There was worry in Xu Zhou's words, and Xu You just remembered that Xu Zhou didn't even know that he had been to the moon so many times before.

After several days of training, these lucky netizens took various aircraft such as aerospace fighters to the moon.

"Well, that's fine, I just need to go to Jijing after a while, and we'll talk face to face then."

After listening to Xu Zhou's answer, Xu You thought for a while before continuing:

But after all, if you want to build a space elevator from the blue star to the moon, the technical difficulty is too great, and it is not a problem that can be solved by the existing technical level.

…………

"Hmm... unless it is to fundamentally change the structure of carbon nanotubes and break the shackles of the previous nanostructure. As for how to design its structure, there is too much knowledge in it."

However, this at least brought a possibility to Xu You, which made Xu You keep a hope in his heart.

Due to the fact that there were too many netizens who participated in the first batch of reservations, only a few netizens were randomly selected, and finally went to the moon to participate in the experience of the lunar underground shelter.

Of course, this has no effect on people like Lou Song who study pure mathematical theory.

Based on his own experience, Xu Zhou gave Xu You a possible direction, but this will not solve too many problems.

This also makes people's willingness to participate in the lunar underground shelter very strong.

The projects Xu Zhou is researching are all very important, and being constantly distracted is definitely not conducive to his research.

"So that's the case. No wonder the call just now, I have always felt a serious signal delay. You must pay attention to safety over there, after all, the moon is no better than the blue star..."

Everyone felt very good about the experience this time. The only thing that is slightly lacking is that some experimental equipment has not been moved over, so it is impossible to conduct experiments like in school.

Xu Zhou made a simple calculation and then gave Xu You's preliminary conclusion.

After Xu You and others lived in the lunar underground shelter, they recorded their life on the moon through some live broadcast platforms or video platforms.

After finishing the lunar underground shelter experience, Xu You and the others returned to Blue Star on the Shenniao aerospace fighter.

"Then is there any other direction, is it possible for carbon nanotubes to greatly increase their strength while keeping the density basically unchanged?"

"Because the underground shelter on the moon has been built, let's experience it in the past. Anyway, we may really move to the moon in the future."

The reason why Xu You didn't tell Xu Zhou these things was because he was afraid that Xu Zhou would worry about him. After all, Xu Zhou's psychological endurance was far inferior to Wu Jing's, and Xu You didn't seem to make Xu Zhou worry about him often.

…………

But now, these ordinary people actually got such an opportunity, which naturally made them feel very excited.

After all, the actual implementation involves too much work, and it is very likely that no results can be achieved in the end.

After seeing their life on the moon, many people feel very envious of this kind of life, which far exceeds their expectations of the underground shelter on the moon.

"Okay, then let's have a detailed discussion in person when we have time. I'm on the moon during this period, and I will return to Blue Star after staying for a while."

You know, only a dozen years ago, there were even a handful of humans who were able to go to the moon.

Although compared to before, carbon nanotube technology has made a very large leap forward, making the idea of ​​a space elevator possible to become a reality.

As expected, when they actually came to the lunar underground shelter, they were very satisfied with the life here.

Hearing the news that Xu You was on the moon, Xu Zhou was a little surprised.

"Okay, I see. I have other things, so I won't talk about it. We'll talk about it after meeting Blue Star."

After all, there is no need to pay for this experience activity. After the experience, you only need to fill in some living experience feelings, suggestions for improvement, and take some recorded videos.

"Why did you suddenly run to the moon? It's dangerous enough there."

Xu Zhou asked Xu You about various safety matters. After Xu You listened to a few sentences, he quickly stopped Xu Zhou.

And Xu You can also use his special ability to carry out brain simulations in his mind to supplement the real experimental data.

The aerospace fighter plane landed at Jijing International Airport smoothly. After getting off the plane, Xu You immediately called Xu Zhou.

After all, this matter is very important, and it is related to the space carrying capacity from the blue star to the moon, Xu You must put it in a higher priority position.

After more than ten seconds, the call was connected.

"Dad, I've already got off the plane. If you have time, you can prepare to come to Jijing."
