Generally speaking, the itinerary of the elderly will not be changed casually.

Today, let's look at the robot, then look at the robot, even if it's in a base, it's a very troublesome thing to temporarily increase the trip. Not to mention that this is a 10,000-acre base, with nearly seven square kilometers.

But the good things in Ning Xiao's mouth obviously have great attraction.

Fortunately, the brothers who are currently in charge of all the security matters of the base are brothers of the same system, and the two sides soon began to hand over various tasks, and within ten minutes, Ning Xiao was able to take the old man to start shuttling around the base.

Walked out of the robot's test factory, got on the elevator to the above-ground part of the base, walked out of the small building car was ready, and after several detours in the base, he came to a small building.

After getting out of the car, Ning Xiao took the old man into the special elevator and came underground again. After a special verification, we finally came to a large underground square.

Standing in the corridor on the second basement floor, you can see through the glass that a huge object in the square is floating in the middle of the underground square, and a temporary elevator has been built around the object, and thousands of engineers are busy in front of this huge object. The elevator lights around the object flickered incessantly, carrying the engineers up and down.

It's a busy scene.

The only thing that puzzled the old man was that he couldn't tell what the huge floating object was at this time, mainly because the shape looked too strange.

"It's ......"

"This is an eighth of the first generation of space research stations, and of course it can also be understood as the first generation of spacecraft. The main range of activity is in the space around the Earth. In the future, it will mainly undertake space scientific research, space construction bases, and ferry missions between the Earth and the Moon.

The giant ship is butterfly-shaped, has a total of ten floors, and the highest part in the middle is 108 meters. Anti-gravity is the primary source of power. There are also two sets of nuclear power systems for space ferrying. In the space environment, gravity is adjusted by a spin column in the middle, and the radius of the rotating module is 450 meters. When drifting by inertia, the middle of the spacecraft only needs to maintain a rotational speed of 0.148 rad/s to produce a centripetal acceleration of 1g, which can make the person in it feel like the earth.

Theoretically, with a full load, the life support system and stored supplies could allow 10,000 people to live on board for three years. If it's a half-human, half-N1 robot, it will last longer. Theoretically, the ship's ultimate speed can reach the speed of light or even faster, because through scientific system deployment, the total mass of the spacecraft can be maintained at zero. But for now, it's just theoretical, because it could take hundreds of years to accelerate it to the speed of light.

But the good news is that once the prototype ships set sail, we will be able to start a series of cross-space shuttle tests. The accumulated data will allow our next-generation spacecraft to have the ability to travel between normal and medium-space, and if successful, the next-generation spacecraft will have the ability to travel faster than light.

The realization of these technologies will be of great benefit to our exploration of the solar system and the transformation of planets. After that, a series of planetary modification plans can be put on the agenda. Our supercomputer is already calculating the resources that may be needed to modify the planets in the solar system, as well as their moons.

Fortunately, we have Earth, a planet that is very suitable for life, which is the best reference. For example, by changing the angular velocity and eccentricity of Mars to obtain gravitational acceleration similar to the earth's surface, we can also calculate how much water and light can be added to Mars to make the surface of Mars have a near-Earth environment, and through artificial deployment of the atmosphere, to meet the needs of human beings, and complete the livable transformation of the planet in a short time.

In other words, the project to explore the civilization of the solar system, which I talked to you about last time, will hopefully be on the agenda after the official launch of our first space research station. We have humanoid robots that can land and build on the surface of the planet in extreme environments, and we also have ferries, and we will have complete planetary transformation technology in the future. ”

Ning Xiao looked at the busy scene in front of him and introduced it one by one.

The old man looked at the scene in front of him in a daze, and subconsciously sighed: "Space opera? ”

Ning Xiao shrugged his shoulders and replied, "No, it's not an opera, it's reality." I am confident that the previous five-year plan will be successfully completed. In addition, a new generation of anti-gravity carrier aircraft in cooperation with Huaxia Aviation Engineering is also under development and construction. That one is simpler, though, and is mostly made from the scraps from which the ship was built, built in their test base.

That product will theoretically have a much higher safety factor than the current spacecraft, that is, the airplane. And the requirements for airports will be reduced. Because the anti-gravity power itself requires a wider fuselage, the interior space will be correspondingly expanded, and an ordinary carrier aircraft can even design a small fire station in it. The entire aviation safety logic is likely to change as a result.

In addition, there is a cooperative product in the atmosphere, and an air rescue platform is in the pipeline. Specifically, it is necessary to build a large-scale aerial work platform that can carry out various crisis responses. By the way, we are also preparing for the investigation of possible accidents of these anti-gravity aircraft in the future, and we use computers to simulate all possible accidents, so as to train our pilots to do targeted simulator training.

In addition to this, our lab has received many invitations to collaborate. The main thing is to develop space tourism projects. But I'm not going to work with anyone else, we have a dedicated team doing market research for space tourism. But it's all easy to do, and our biggest competitive advantage is that we can enjoy all the possible space tourism programs without having to go through special training.

This includes, but is not limited to, a 360-degree view of the Earth from space, weightlessness experience, a close-up observation of satellite operations, a lifting telescope experience in space, and so on. Of course, there are also projects with simple training, such as spacewalks. By developing these commercial projects, we will be able to achieve self-sufficiency in the entire space development even in the early stages. ”

After Ning Xiao finished introducing him, the two of them seemed to have lost interest in talking. Just quietly watching the busy engineers in the huge underground plaza.

Compared to the one-eighth of the spaceships in the center of the huge square, all the people are like busy worker ants, making people unconsciously feel the insignificance of individual human beings. Especially the thought that such a huge spaceship is really lifted off and so small compared to the huge earth can make people feel powerless.

But when you think that a small human being can change a huge planet through various means, the feeling is different. It is easy to create the illusion that man can overcome heaven.

But then again, the future described by Ning Xiao at this time is indeed an expression that man can overcome the sky.

After all, the transformation of the planet is strictly to change all natural attributes, so that nature can change according to the will of human beings. Go by the rules and then change the planet.

Eventually, the silence turned into a sigh: "Will I be able to see the Earth from Mars in my lifetime?" ”

This question made Ning Xiao think about it very seriously, and only after about ten seconds did he answer: "No problem, theoretically speaking, the albedo of the earth is relatively high, about 37 percent. If you need this, you can choose Mars to observe the Earth at a large distance, when the right triangle of Mars and the Sun is at its maximum, and it looks the largest and brightest. Well, about six years from now is the best time to observe. I'll accompany you to see it then. ”

The old man looked sideways at Ning Xiao in astonishment.

Then he didn't say anything, just smiled and nodded, then raised his hand and patted Ning Xiao's shoulder and said, "Then please." By the way, what do you think is the most important thing right now? Or how do you fit in with your planet transformation plan? ”

"It's people! And only people! In particular, a large number of young people of the appropriate age to marry and have children are the most scarce resources in the interstellar era. ”

Ning Xiao immediately replied without hesitation: "The most scarce resource in the space age is always people themselves!" A large population is the cornerstone of the continuation and development of civilization. After the calculation of civilization, if the transformation of Mars is successful, then more than a dozen planets in the solar system that can be adapted to human beings have been included in our choice. For example, Ceres, Europa, Ganymede, Titan, etc. in the asteroid belt are all potentially habitable planets. It takes a lot of migration and the combined efforts of several generations to truly spread civilization.

It takes a large population base and the most appropriate educational model to incubate enough geniuses to advance these planets and recreate the definition of interstellar civilization. We need humanity to create more transgalactic needs and use them to advance science. More living space will make it easier for us to understand the mode of operation of the universe and the imprint mode of civilization. We need these different models to have a deeper understanding of nature.

Once we conquer the solar system, we need more people to embark on extraterrestrial adventures. But before that, Huaxia had to control enough habitable planets to create a stable enough rear. These habitable planets will inspire everyone to explore. When that day comes, we will have enough population to support biological selection pressure, to pilot spaceships to explore regions outside the solar system, to find more habitable planets, to send more people out, so that civilization can blossom and bear fruit outside the solar system.

So for the future, we need a younger, healthier social composition with a more age structure. Young people between the ages of eighteen and forty will become the most important resource for the entire human civilization. In other words, starting a wave of fertility now will be the main force of interstellar migration in exactly twenty years. ”

Obviously, Ning Xiao had been thinking about this question for a long time, and said it almost without any hesitation.

Of course, this task is also extremely difficult. Explosive population growth means diluting resources per capita. The most critical problem is also the change of the concept of fertility, the more developed the society, the more conservative the concept of fertility of human beings.

"Oh, any good advice?"

"For high welfare guidance, we have made a model with supercomputing. If you want to encourage childbirth in this era, you can probably only use high welfare guidance, and it is a continuous high welfare guidance. For example, from the two-child family from the beginning of the preschool education free, a large area of convenient and effective preschool education institutions, and even a large number of monthly childcare subsidies, so that multi-child families can have no worries about food and clothing, but also do not worry about education, only in this way can the fertility rate rise in a short period of time. ”

"Where does the money come from?"

"High-tech products can bring high added value, our base has been considering the output of technology in the civilian field, is to drive many industries to leave high value-added profit margins, the key is to distribute the profits in accordance with the rules for the corresponding fields. Artificial intelligence technologies including faster, our N1 humanoid robots, and future anti-gravity delivery technologies can all bring high profits if you find the right partner. ”

The old man looked at Ning Xiao in surprise and asked, "Do you plan to take out this money as a special subsidy fund?" Advance the future sustainable profits of this base? ”

Ning Xiao smiled, then picked up the kitten next to him, stroked the soft cat hair and said: "The times will eventually become different, if we overlook the development of human civilization from a more macro perspective, we need a large population and a more reliable granary." The Earth, as the parent star, will be able to assume these functions in the future. Our greatest advantage in this era is that we can see the most scarce resources in the future earlier than others, and then make targeted policies. ”

The old man nodded and asked, "If your plan goes wrong or suffers a setback, such as your planet transformation plan is not going well, and the ideal space migration is postponed indefinitely, how do you think you should deal with the possible fertility wave?" ”

Ning Xiao replied seriously: "This is a huge plan with a 20-year cycle, and it is designed to be fault-tolerant. In addition, even if the planetary transformation project does go wrong, the burst of productivity will be able to absorb the increased population, not to mention that according to our model, even if the relevant welfare policies are formulated and enacted now, the most optimistic estimate of the first wave of fertility will not arrive until three years later. Three years is long enough time for us to see what's next. ”

This sentence made the old man stunned, and he sighed for a while: "Yes, three years...... I remember the last time you described the strategy plan in the solar system to me, it was just over two years ago, right? The year you won the Fields Medal, right? ”

Ning Xiao nodded.

"Okay, you write a formal report and give it directly to Xiao Su. Xiao Ning, I'm afraid you're going to make a big gamble. The old man raised his hand, patted Ning Xiao's shoulder, and said with a long sigh: "Let's get here today, have you named this spaceship?" ”

"Uh...... Because it will mainly undertake the task of ferrying the earth and the moon in the future, it is planned to be named Wu Gang. ”

"Wu Gang? Well, remember to notify me when the Wu Gang sets sail. ”

"No problem!"
