Su Zhe and the other five people walked in the passage under the leadership of the commentator. After passing three doors, a light appeared in front of them.
After walking out of the last door, the five people saw a patch of green, and some cattle and sheep could be seen scattered among the green.
The five Su Zhes were floating in the air and flying slowly, while the commentator was explaining. Sky Ranch is different from space farms, which are divided into zones. The ecology of different zones is slightly different. Space Ranch is different. It is a whole. The entire ecology simulates the ecology of grassland. There are grasslands and space ranches.
The main space of the Space Ranch is 100 meters high, which can simulate night and day, as well as rain, snow and other weather conditions.
Zuo Dajun looked left and right, up and down, and said with a smile: "If you didn't look around, you would have thought you were really on the grassland. Look, in addition to the grass, there are a lot of leeks, and they are all blooming. Really, this It’s really no different from the grassland.”
"Look what you said. Didn't the commentator just say that the space ranch simulates the ecology of the grassland. Except for these plants and small animals, the microorganisms are all the same. Everything about the soil and everything is according to the standards on the grassland. Come." Fan Xiaoming reminded.
"This... put it this way, this is replicating the ecology of the grassland. In this case, can we live here?" Zuo Dajun asked with a smile.
Fan Xiaoming nodded and said: "Of course, those cows and sheep can survive here, and we humans can too." Bao Qizheng nodded and said: "The research on space ranches, especially the research on grassland ecology, is what we create Preparing for humanity’s space home.”
"Yes! I know that." Zuo Dajun said with a smile,
"As for building human homes in space, or building human settlements in spaces other than the earth, there are basically two routes. One is to still use those celestial bodies, such as transforming the moon and Mars, and the other is to transform the moon and Mars. Regarding the construction of human homes in space, such as space cities and ecosystems suitable for human survival, judging from the current debate between the two parties, the former is at a disadvantage and the latter has taken the initiative." There are many people who support these two routes, but At this stage, the former is still a little less interesting, while the latter is more maneuverable.
Take Mars as an example. Supporters of the former want to transform Mars to make its environment suitable for human survival.
As far as current science and technology are concerned, it is basically impossible to transform Mars into an environment like the Earth, especially the overall transformation.
Among them, the most difficult problem to solve is the problem of gravity, and then there is the problem of Mars' atmosphere and magnetic field. The problem of gravity is really difficult to solve, at least at this stage.
After all, we haven't yet fully understood what gravity and gravitation are, let alone changing gravity.
As for the atmosphere and magnetic field of Mars. If you really want to do it, that is to say, if you act recklessly, both problems can be solved.
If the atmosphere is really not a problem, put a coat on Mars, and the magnetic field can be created artificially. Supporters of the latter attack the former for saying that Mars' gravity cannot be changed.
According to the latter, human beings' homes should be built strictly in accordance with the earth's environment, whether it is gravity, magnetic field, pressure, etc., they must be exactly the same.
The purpose of this is also very simple, that is to prevent the natural differentiation of human beings. For example, if humans survive on Mars, even if other environmental conditions are the same, but the gravity is different, over time, the people living on Earth and Mars will differentiate, and they will divide into two groups after a few years.
This situation should be avoided if it can be avoided. Compared to the former to transform Mars, the latter is much simpler.
In the eyes of these people, Mars can only be regarded as a place for resource extraction. It can be said that except for the earth, all other celestial bodies are resource providers.
From the perspective of these people, apart from the earth, there is no way to find a living environment in the universe that is exactly the same as the current stage of the earth.
At this stage, these people support the construction of space cities, ecosystems, etc., to create a living environment that is exactly the same as the earth's environment.
After we understand gravity and gravitation in the future, there will be no need to transform Mars or anything else. We can directly use Mars and other celestial bodies as resources to build an upgraded version of the Earth, or an upgraded version of the solar system.
This is much simpler than transforming those celestial bodies. So far, the latter has significantly more supporters than the former.
It sounds funny to say that the special zone led by Lingzhou University of Technology is pursuing two routes at the same time, and related projects are under development.
It's just that the reformists are still in the theoretical stage. After all, the celestial bodies are different, and the transformation plans are different. Furthermore, the problem of gravity cannot be solved, which means that the reformists are still in the theoretical stage.
But even so, a celestial body in the solar system was selected as the object of transformation. The celestial object being transformed is a satellite of Jupiter.
The current modification work is mainly focused on this satellite. The constructionists are different. They have entered the practical stage early, such as space farms, space ranches, ecological circles and so on.
This is especially true for those space cities being built. This is a special zone led by Lingzhou University of Technology. The special zones led by Tsinghua University and Yanda University are completely different.
The former overwhelmingly supports the construction faction, while the latter overwhelmingly supports the reform faction. Both are running wild on the supporting lines.
The Qing Dynasty directly targeted the Coyinbo Belt and wanted to use the celestial bodies in the Coyinbo Belt as resources to build human homes.
This human homeland is called the Second Earth. Its size is similar to that of the Earth. The difference is that the Earth relies on the sun to maintain its environment and cannot escape its orbit.
Furthermore, the earth's environment is directly affected by the sun. The Second Earth is different. Its energy comes from controllable nuclear fusion technology. As long as there is enough energy and fuel, the Second Earth can sustain it.
As for the biggest advantage, it is that the earth can move freely in space. Tsinghua University’s ambition to build a second Earth is not small.
The ultimate goal is to fill the entire universe with a second Earth. According to what Tsinghua University said in its promotion, the Second Earth can be copied in large quantities. It can be docked in a star system and run on the energy of stars, or it can wander in the dark space of the universe and rely on its own nuclear fusion energy. run.
Theoretically speaking, Tsinghua University’s Second Earth is completely feasible. For now, the only bad thing is controllable nuclear fusion technology.
You know, the special zone led by Tsinghua University has made great efforts to create a second earth, and 80% of the research projects carried out are related to the second earth.
If nothing else, as for the proton fusion device led by the Jiutian Research Center, Tsingta University was even more proactive than the Jiutian Research Center and took over a lot of the hard work.
Compared with Qing University, Yan University is a reformist school. Transform celestial bodies and transform star systems. Speaking of which, when development reaches a certain level, the constructionists and the reformists reach the same goal by different routes.
Fan Xiaoming smiled and said: "For now, the constructionists have an advantage. When we master the controllable nuclear fusion technology, the advantages of the constructionists will be even greater. I didn't see that Tsinghua University is busy building the proton fusion device." After getting busy, Tsinghua University’s Second Earth is not just for fun, it’s just waiting for the proton fusion device.” Xu Zhengping nodded and said: “To be honest, we had similar plans originally, but we didn’t expect that Tsinghua University would take the lead. Look. Look, as long as it is helpful to the construction of the second Earth, Qingdao University will not be active, such as the construction of the proton fusion device, the beam channel across the solar system, and the expansion of the light column project." Bao Qizheng said seriously : "Tsinghua University now basically invests most of its resources in the Second Earth. To be honest, Tsinghua University is really spending money. Now it is preparing to build a Second Earth, such as large celestial bodies. Mining equipment, cargo flying saucers, engineering mechas, etc. are all being prepared.”
"Yes!" Xu Zhengping said with a smile,
"The people at Tsinghua University are very smart. When we launched detectors towards Proxima Centauri, Tsinghua University launched a large number of detectors to the Coinber Belt. The total number of large and small detectors exceeded 100,000. , not to mention, a large number of celestial bodies have been discovered in the Coyinbo Belt, which are all resources." It was known before that there were many celestial bodies in the Coyinbo Belt, but after exploration, it was found that the celestial bodies in the Coyinbo Belt were smaller than those in the past. A lot more were detected.
There are more than a million celestial objects with a diameter of more than 100 kilometers, or even more, and more than 100 celestial objects with a diameter of more than 2,000 kilometers.
In other words, the Coyinbo Belt has more resources than the asteroid belt. Fan Xiaoming said: "That is, the beam channel across the solar system, the light beam project, and the SS-defense system. These will be built in two or three months. Partial coverage, partial coverage, everything is To prepare for Qingda University to mine the celestial bodies in Ke Yinbo’s belt to build a second earth.” Zuo Dajun smiled,
"To be honest, I quite admire Tsinghua University. To build a second earth, the most important thing is that it is about the same size as the earth. Fortunately, the second earth is hollow. If it is the same as the earth, then even if you bring Ke Yinbo, so Even if all the celestial bodies are mined, it may not be enough." Bao Qizheng shook his head and said, "This is not necessarily true. To be honest, there are still many celestial bodies hidden in the outer reaches of the solar system. It's just that these celestial bodies do not emit light and are difficult to find. That’s all.” Su Zhe nodded and said, “I support Tsinghua University’s plan to launch Second Earth. According to the parameters given by Tsinghua University, under the condition of self-sufficiency, the upper limit of the population of Second Earth is 100 billion.” Although he said He is from Lingzhou University of Science and Technology, but he was also involved in the design of Second Earth.
Speaking of which, many people were involved in the design of Second Earth, including those who support the reformists.
"One hundred billion, so many people." Zuo Dajun looked shocked. Fan Xiaoming smiled and said: "This is based on the traditional method of producing food. If we use synthetic methods to produce food, the number will increase tenfold, and the population that can be accommodated can reach one trillion." Hearing this. With a population of one trillion, Zuo Dajun was even more shocked.
"A population of one trillion is more than a hundred times the current population of the earth. It's really scary. Of course, such a small number of people is nothing to the entire solar system. To the entire universe, such a small number of people is just drizzle. When we humans develop and roam the entire universe, how big will the total number of humans be?”
"Dajun, you are asking this question. Now we don't even know how many star systems there are in the universe." Fan Xiaoming smiled,
"If you want me to answer, I can only answer this. For a star system the size of our solar system, it is no problem at all to support a population of one hundred billion. At this level, we are still extremely conservative. If you think about the universe How many star systems are there?"
"How many star systems there are in the universe, I guess no one can give an accurate number now." Zuo Dajun thought for a while and said,
"Well, many star systems have multiple stars and the environment is so harsh. How can humans survive? Star systems with multiple stars are extremely unstable and cannot have a stable environment. It is impossible to survive at all." Fan Xiaoming smiled and said: "Like It is impossible for our earth to appear in that kind of environment, but it is not the second earth. You must know that the second earth is self-sufficient, and the second earth can fly freely, and its position is not limited. As long as there are enough fusion nuclear raw materials, and with the development of science and technology, the Second Earth can continue to iterate. It is really hard to say what the Second Earth will become in the end, but what is certain is that the Second Earth will It has become extremely powerful, extremely powerful, even beyond our current imagination." If it continues to develop along the path of Qingdao University, Second Earth will be really promising if it continues to iterate.
It can be said that Second Earth can carry all human imaginations. A separate Second Earth can serve as a complete human civilization.
Second Earth can exist in a star system or wander around in the universe. Zuo Dajun thought for a while and said: "It's true that Second Earth is different from Earth. Second Earth can be traveled around. As for those stars, celestial bodies, etc., they are completely resources and energy. In this way, Second Earth's The future is bright. We can completely copy the Second Earth continuously and fill the entire universe with the Second Earth." Xu Zhengping smiled and said, "That's what people at Qingda University think, so they put their treasure in it. On the Second Earth, but having said that, the Second Earth is very suitable as a carrier of human civilization. Of course, Qing University is a construction school, and its goal is to spread the Second Earth throughout the universe. Yan University is a transformation school, and it not only wants to Transforming celestial bodies and also transforming star systems, the goal is not small, so that every star system in the universe has a planet suitable for human survival."
"This... both Qingdao University and Yanda University have such a goal. Our school is ours. What is our goal?" Zuo Dajun asked with a smile.
"Our goal..." Xu Zhengping thought for a while and said,
"Our goal is to explore the universe while consolidating the solar system, so that our solar system will always be the most powerful human being in the universe." Zuo Dajun was a little excited,
"This is a good goal... Has the design of Second Earth been completed? Can we visit Second Earth in the virtual universe?"
"This..." Fan Xiaoming looked at the time,
"Okay! We only have half an hour, let's go take a look and then come back."
