Zuo Dajun caught up with Fan Xiaoming with a smile and said with a smile: "Why don't you leave first and do your own thing. Anyway, you can visit these at any time. You have also seen the most important artificial uterus technology, so the rest doesn't matter. ." The main purpose of their visit this time was to visit the artificial uterus technology. Now that the visit is basically over, they can visit it any time later.
Xu Zhengping nodded and said: "Yes! You can go to the National Observatory to find your partner now. The wedding the day after tomorrow is indeed a bit urgent." Su Zhe smiled and said: "How about you leave first, and I will accompany you later. Visit once." Bao Qi nodded with a smile.
"My sister-in-law is probably very excited now. You'd better go there as soon as possible." Fan Xiaoming smiled awkwardly and said, "Well, my partner is busy and won't get off work in three hours. It's too early to go there now. Let's continue. If you visit well, you can't see the fully developed calves, nor can you see the sheep, but you can see the rabbits and mice." The pregnancy cycles of cows and sheep are longer, while the pregnancy cycles of rabbits and mice are relatively short. Too short.
Zuo Dajun looked surprised.
"What! There are rabbits and mice here. I can understand the rabbit, but what about the mouse?" This is a space ranch. He can still understand if rabbits are released in the space ranch. After all, even if the rabbits don't pass through the artificial uterus, Reproduction, its natural reproduction is also very fast, whether it is rabbit fur or meat, it is also a good product.
But the mouse was something he couldn't understand. Relatively speaking, there are many people who eat rabbit meat, but there are too few people who eat rat meat.
Fan Xiaoming smiled and explained: "Not just rabbits and mice, let me put it this way! All animals that exist on the grassland will be found here. After all, the space ranch simulates the environment of the grassland. Since it is a simulation, it must be fully simulated. ." The space ranch simulates the natural environment of the grasslands on the earth. It is a comprehensive simulation from microorganisms to plants to animals, etc., so it is not difficult to understand that there are rabbits and mice.
"That's it! I understand!" Zuo Dajun smiled,
"Then let's go faster. I want to see the difference between rabbits and mice cultured in artificial wombs and those bred naturally."
"What's the difference? Of course they are exactly the same." Xu Zhengping said with certainty. Fan Xiaoming said with a smile: "The next thing we will look at is the reproduction of sheep, and then the reproduction of other mammals such as rabbits and mice. In fact, there are still only a few mammals reproduced in artificial wombs in the space ranch. Ecosystem No. 1 is complete. As long as They are mammals that exist on the earth. No, it should be said that as long as there are animals and plants on the earth, they will be researched and bred in Ecosystem No. 1, such as our long-standing tigers, lions, giant pandas, etc." Zuo Dajun nodded. Said: "I understand this. Ecosystem No. 1 simulates the ecology of the entire earth. Ecosystem No. 1 that exists on the earth must also be present in Ecosystem No. 1." Don't look at Ecosphere No. 1 as small, but Ecosystem No. 1 simulates the Earth. The whole ecology.
Not only Ecosphere No. 1, but also Ecosphere No. 2, which is three hundred kilometers away, is also used to simulate the ecology of the entire earth.
As for the research on Ecosphere No. 1 and Ecosphere No. 2, it is actually our preparation for building a living environment for human beings in space in the future.
For example, the Second Earth being studied by Tsingta University and the transformation of celestial bodies by Yanda University provide support for the research data of Ecosphere No. 1 and No. 2 Ecosystem.
The earth's ecology is inherently complex, and there is a process for studying it clearly. Xu Zhengping said with a smile: "It's like this. There is a long way to go to study the earth's ecology, but there are so many people studying it! This is related to the creation of human beings' living environment outside the earth, and everyone attaches great importance to it." The ecology of the earth is quite complex. If you want to understand the ecology of the earth, you will have to invest a huge amount of manpower and material resources. In the past, it was just a bit of research, but now it is different.
Resources and energy can be continuously invested. If they are poor, then the waste is also in manpower. Although there are many more people engaged in scientific research now than there were a year ago, the demand for research is still less.
In the past, there was no solution because resources and energy were limited, and a large amount of manpower had to be used to produce supplies to ensure survival.
Now that's completely different. Ninety-nine percent of the manpower has been liberated from the production line, and the vast majority of them are directly or indirectly involved in scientific research work, but even so, there are still few people.
The current situation is that there are sufficient resources and energy, but there is a serious shortage of manpower. The ecology of the earth needs to be studied, which means that the entire operating mechanism of the earth needs to be studied, plus the development and research of the solar system, cutting-edge technologies, and finally the study of outer space in the solar system and so on.
There are too many things to study and too many projects to study. But there is a serious shortage of manpower.
For now, the development of science and technology and the development of the solar system are severely restricted because manpower cannot keep up with demand.
If the proton fusion device is successfully developed, it means that humans have mastered controllable nuclear fusion technology, and humans will have the ability to navigate interstellar space.
At this time, the manpower gap becomes even greater. It is for this reason, coupled with long-term plans for human development, that population increase plans emerged.
The increase in population is not only related to current development, but also related to the long-term development of mankind. Fan Xiaoming nodded and said: "Yes! Compared with the past, there are not too many people studying the earth's ecology now, but for the projects that need to be studied, these people are still too few now. Even if it increases a hundred times, it will not be too much."
"This is the truth. There are too many unknowns in the universe waiting for us to study. Even if there are more people, there will still be endless research projects." Xu Zhengping smiled,
"This is the population increase plan. Even from now on, the first wave of people who can join the research will have to wait for more than ten years. But there is nothing we can do about it. But having said that, we can still wait for this time, that is. More than ten years later, our science and technology will develop at a faster pace due to the rapid increase in the number of people." Zuo Dajun said with a smile: "Of course, for our next generation, whether it is education or other things, they will It is definitely better than us. As for burying talents, it will not happen. Quality plus quantity. Even if scientific research becomes more and more difficult as time goes by, the number of new scientific research manpower will be astronomical. In sixty years, the number will be It can reach one hundred billion. Conservatively speaking, half of them will participate in scientific research. What will it be like if fifty trillion people are engaged in scientific research." For now, repetitive tasks such as production are quilt
"Robots" have replaced them, and what they can do now is either service-oriented jobs or scientific research, and the vast majority of them are engaged in scientific research.
As for those who lie flat, they are in the minority. This is the case now, and it will probably be even more so in the future. Except for innovative work such as scientific research, all other work will be
Replaced by "robots". This is already an established fact. As time goes on, the proportion of people participating in scientific research will only get higher and higher.
Fan Xiaoming smiled and said: "Science and technology are developing explosively! To be honest, even if so many people participate in scientific research, it is unrealistic to figure out all the rules of the universe in a short time. The discovery of some things requires a certain amount of time." An environment like this cannot be created by a sea of people." Zuo Dajun said nonchalantly: "If we want an environment, we create the environment. Anyway, there is nothing wrong with having more people. We have resources and energy, and with enough people, As long as we persist in research, we will be able to figure out the nature of the universe sooner or later. In terms of scientific research, I think the human sea tactic is useful."
"This is not necessarily true. Some people find that just having too many people is not enough. It depends on opportunities." Fan Xiaoming explained,
"What's more, the further you go, the more difficult the research becomes. But having said that, no matter what the situation, we just insist on doing research. It's not that the human sea tactic is not good, it also depends on the opportunity." Fan Xiaoming and Zuo Dajun, you two I spoke word by word.
Soon, Su Zhe and the others, led by the commentator, arrived at the sheep breeding area. Seeing that Fan Xiaoming and Zuo Dajun were talking endlessly, Xu Zhengping reminded him: "You two can do it. Stop arguing and have a good visit." After hearing what Xu Zhengping said, Fan Xiaoming and Zuo Dajun stopped.
The five people began to visit the sheep breeding area, which is actually the sheep breeding production line, which is similar to the cattle breeding production line.
It also starts with the proliferation and culture of sheep oogonia and spermatogonia, and ends with the implantation of sheep blastocysts into an artificial uterus.
Seeing the end, Zuo Dajun said with a smile: "The previous ones are almost the same, and I can't even see the difference. The difference is that at the end, the sheep's artificial uterus is smaller than the cow's." The comparison between the two is much worse.
Fan Xiaoming smiled and said: "What you are saying is, how big is a sheep, how big is a cow? A newborn calf is as big as an adult sheep. How do they compare? You will know more when you see the size of the artificial uterus of rabbits and mice. I'm surprised." Zuo Dajun smiled awkwardly, looked at the undeveloped lamb in the artificial womb and said, "Move it, this lamb is fully formed, and it will probably be born soon." As soon as he finished speaking, the narrator explained that it would take another three months for the earliest batch of sheep to be born.
Hearing this, Zuo Dajun asked with a puzzled look on his face: "The cattle and sheep here have not grown up yet, so where do the cattle and sheep on the grassland come from?" Xu Zhengping shook his head and said, "You... You are asking, do you need to say it? Those are transported directly from the earth. Such a large space ranch has been built, and it is not easy to transport some cattle and sheep."
"Okay!" Zuo Dajun said with a smile,
"Let's go see rabbits and mice. I think we can see the birth of rabbits and mice." Soon, Su Zhe and the other five arrived at the rabbit breeding production line.
Everything started the same. The five of them took a casual look and came to the final artificial uterus area. From the initial blastocyst of a newly implanted rabbit, to the formed embryo, to the rabbit moving around in the artificial womb.
At the end of the movie, I saw a lot of artificial wombs being taken away by robots. According to the narrator, the rabbits in these artificial wombs that have been removed have completed their development and will be born soon.
Su Zhe and the other five followed one of the robots to another area. In this area, there are many robots delivering babies to these little rabbits.
Su Zhe and the other five watched the robot in front of them operate bit by bit. The robot opened the artificial uterus and took out the rabbit. After a period of handling and cleaning, the rabbit was placed in a small insulated box.
The incubator containing the newborn rabbit was sent to another area. There are a large number of little rabbits in this area. These little rabbits bark non-stop. There are also a large number of robots taking care of these little rabbits.
Zuo Dajun looked at the newly born little rabbit in front of him that had not yet opened its eyes, and said with a smile: "This little rabbit is so cute... As for the rabbit's artificial uterus, it is really small, only about the size of a thermos bottle."
"Mouse ones are really small." Fan Xiaoming reminded with a smile. Zuo Dajun nodded and said: "I guess so...will these rabbits be raised here for a period of time, and then put directly on the grassland?"
"It will last for a while, but not here." Fan Xiaoming pointed to a robot holding a small rabbit in its hand and said,
"We will know after following the robot. These newborn rabbits will only stay here for a while. During this process, the rabbits will be examined and their blood will be taken." Zuo Dajun was a little confused.
"I can understand the examination. What is the purpose of drawing blood?" Bao Qizheng, who was standing next to him, explained: "It is used for genetic material sequencing, and some of the blood samples of the little rabbit will be retained. In fact, when the little rabbit was born, If you pay attention, you will know that the umbilical cord blood of the little rabbit will also be frozen and preserved."
"Why do we need to sequence it? What are we keeping these for?" Zuo Dajun became even more confused. Bao Qizheng smiled and said: "The genetic information of the little white rabbit is retained. As for the blood, it is mainly for research. To put it simply, it is to collect the genetic material and related life details of this rabbit. What we are considering is not Now, we have to consider the long-term future." Xu Zhengping nodded and said: "With the development of science and technology, we want to master the genetic information left by this rabbit, or all the data of this rabbit's fertilized eggs. With information, we can use substances to directly synthesize fertilized eggs of rabbits, and then develop into rabbits." Fan Xiaoming nodded and said, "Speaking of which, this was proposed by Tsinghua University and Yanda University. According to them, there will be data-based Everything will be digitized. By then, as long as there are enough resources and energy, coupled with the corresponding technology, we can bring the life of rabbits back to life."
"This...this can still be operated like this. According to this, whether it is a plant, an animal, or a microorganism, as long as there is data information, there is no need to bring seeds, fertilized eggs, etc., and it can be copied directly, right? ! Is it the only way?" Zuo Dajun said and looked at Su Zhe.
