    On the third day after Ambassador Chen left for China, Youde casually found an excuse to have tea with Sophie.  As soon as she sat down, Sophie said: "Dad, you have really launched a very crazy plan, an orbital elevator? That is an elevator 35,786 kilometers long. Even if you use a piece of silk as an elevator rope,  , it will also be very heavy. Of course, it is impossible to use silk to make an elevator rope, because it cannot even support its own weight, and it will break immediately, and it does not require any force other than gravity. " "That's why I have to do it.  Let me drink tea with you. I want a material that is high-strength, light-weight, and has one of two properties: insulating or superconducting. " "What do you think I am, God?" "In another time and space, I am.  I know a material that can meet this requirement, called carbon nanotube, which is a polymer structure composed of carbon atoms. It is reinforced with materials that have high strength, unique electrical properties, and are very light. " "  Made of carbon?" Sophie raised her eyebrows, "You mean it's a type of diamond?" "No, it's similar." "Interesting, I'm already convinced that some macromolecules will have strange properties.  By using elements to construct macromolecules, it is possible to produce the materials you need, Dad. ¡°What I want is not macromolecules. In the original time and space, carbon nanotubes were generally in powder form. Carbon nanotube monomers were prepared by humans.  It's very small, so it looks like a powder. I need you to make a whole carbon nanotube and test its properties." Sophie stared at Lin Youde.  In fact, Lin Youde didn't know whether it was possible to prepare a whole carbon nanotube. He didn't even know whether this thing existed in theory. In addition, he certainly didn't know the properties of a whole carbon nanotube in another time and space.  , humans just use electromagnetic technology to create super-aligned carbon nanotube arrays, and then pull out the film, which is actually an arrangement of multiple carbon nanotubes; and then add carbon nanotubes to various raw materials to obtain various properties  .  Human beings in another time and space have never produced nanotube monomers as large as the carbon nanotubes described by Lin Youde. Lin Youde was full of curiosity about the properties of that thing.  Even if carbon nanotubes cannot be used to directly produce cables, if carbon nanotube-reinforced composite materials can be produced in advance, a suitable composite material may one day be found.  Humanity in another time and space is already very close to this goal. Some scientists even claim that as long as someone invests enough money, a space elevator can be built.  Lin Youde didn¡¯t know if the person who claimed this in another time and space was talking nonsense, but Lin Youde was ready to give this idea a try in this time and space. He had been preparing for this for so long and had so many resources in his hands.  "Okay," Sophie may have sensed Lin Youde's determination from his expression, "I'll give it a try. Of course I will also try other things. I originally planned to make more macromolecules to test their properties.  "As long as you give me time, maybe I can make some materials." Lin Youde nodded happily, and suddenly asked: "Where are your fake breasts? Are you doing all these things?"  "Fake breasts?" "How is that possible!" Sophie retorted loudly, "I do this because it gives me the pleasure of being a creator. Think about it, I have created something that has never existed in nature!"  What a great deed of the same nature as the creation of the world!" Lin Youde half-opened his mouth, and then he convinced himself: Although Sophie is already in her twenties, it is not surprising that she still retains the attributes of a middle school student at this age.  Sophie looked eager to give it a try. She stood up and took a deep breath: "Although it's rare for you to invite me to drink tea, Dad, I can't help but make the kind of carbon nanotubes you mentioned. I have never done it before."  I thought about using carbon as a material, because I think there are too many macromolecules in the world that contain carbon. Now it seems that I have been delayed by my own subjective feelings. " "It doesn't matter, now you know the right way forward.  "It's not necessarily correct. Dad, didn't you build an orbital elevator in your original time and space? Maybe it was because you ran in the wrong direction." After leaving these words, Sophie left quickly.  He walked into the garden of Sanssouci Palace and disappeared into the tree-lined road leading to the laboratory.  Lin Youde continued to stay where he was and drink tea.  Everything that can be done has been done. Starting from January next year, the cabin sections that make up the counterweight should be launched one after another. Thirty years from now, there will be a giant giant that has never been seen in human history in the synchronous orbit over Southeast Asia.  A man-made celestial body, and then, if all goes well, cables will be dropped from that body, and the greatest building in human history will finally be completed.  ¡°I don¡¯t know if God will rain heavily this time.?¡± Lin Youde raised his head and looked at the top of the pavilion that was full of murals. ¡°Thirty years is indeed a bit too long. We need to urge those people to build a space shuttle that can carry twenty tons of things at a time, which is different from the current one.  There is still a big gap in transportation capacity.  " Lin Youde is actually very anxious now. He hopes to build the orbital elevator in a few years and then start the colonization plan. But it is useless for him to be anxious now. Everything has to be done slowly. In fact, those scientists should also be very anxious.  , some of them are much older than Lin Youde. With the current progress, they may never see the completion of the orbital elevator, but they still devote themselves to this great plan with full enthusiasm. Lin Youde suddenly wants to see it.  He looked at the starry sky, but it was broad daylight. Even if he walked out of the pavilion and raised his head, he could only face the scorching sun. So Lin Youde closed his eyes and unfolded the picture of the starry sky in his imagination. He imagined the surface of the moon and imagined it.  On the surface of Mars, his thoughts then flew to one planet after another, until he left the solar system. There are no traveler probes in this time and space, so the scope of human activities is still within the solar system, and in another time and space, that small space.  The probe has left the solar system with the courage and pioneering spirit of mankind, heading towards the vast sea of ????stars. How long will it take for humans in this time and space to take this step? Lin Youde thought about this question, and then hummed softly to the space system.  "In the army that conquers the universe, I am the one who contributes silently" Lin Youde didn't know that at this time, Oh Jiang was sitting there on the roof of the pavilion, swinging her little feet along with his humming.
