Chapter 554: Bright Future Prospects

"As for the fourth technology, it is not a space technology per se, but a technology used to launch large-mass objects." I explained: "Everyone knows that launching a spacecraft is a very energy-consuming behavior. Like what we are doing now Just launching some satellites weighing a few tons is quite difficult, and in the age of space, many large space battleships may weigh more than 10,000 tons. Although the power of a spacecraft of this level will be very strong, if it relies on its own power to escape from the surface of the planet, it will be very difficult. It consumes a lot of energy. Therefore, some planets will have special devices to help large-tonnage spacecraft take off."

"What kind of device is it?" someone asked.

"Actually, it's not a special device. It should be similar to an electromagnet. The difference is that this thing is directionally emitted and uses gravitational waves instead of magnetic fields."

"Gravitational waves?"

"Yes. To put it simply, it is to set up a huge gravitational wave generating device on the surface of the earth, and then let the spacecraft that needs to enter space enter the area above this device. When this device is activated, it will generate an upward gravitational wave, supplemented by A special repulsive field boost can send the spacecraft directly into space without the spacecraft's own engine starting at all.

This technology is widely used on the planets of the creators. Its launch cost per unit mass is higher than that of a space elevator, but its construction cost is very low, the construction difficulty is also very small, and it is simple to maintain. The most important point is that orbital elevators can transport scattered cargo or small spacecraft that can be loaded into containers. However, for some large spacecraft, orbital elevators are obviously not suitable. This kind of device can just complement the orbital elevator. It is a launch device with high safety and very low construction cost. The creators' military launch systems are basically based on this, while the orbital elevator is more like civilian technology.

As far as our current situation is concerned, we simply do not have enough technology to complete the orbital elevator. And even if we have the technology, we don’t have the time. But the structure of this launcher is very simple. According to my estimation, we can complete at least thousands of these things around the world without affecting other construction projects. "

"So what is the use of this launcher?" asked a tycoon.

"It has many uses. For example, the spacecraft can go directly into space without consuming any fuel. This means that our spacecraft can save some more fuel. In addition, because of this technology, everything we build from now on will Immigration ships can be modified to reduce the size of the fuel tanks and free up some space to store more sleeping cabins. In this way, more people can be taken away without adding additional workload. Don’t you think this Is this a good thing? Even if the saved space is not used to accommodate people, it is a good choice to take more resources and equipment with you. Don’t you want to take away all the antiques, famous calligraphy and paintings on the earth? "

Hear my last words. The reaction of these big guys was obviously different.

No matter how far society develops, there can never be true equality between people. Although due to the great crisis of human extinction, all countries have been ruthless this time and try to leave as much space as possible on immigration ships for manned use. However, even this does not mean that these tycoons will leave empty-handed. Many of them had actually planned to leave with some jewelry, antiques, calligraphy and paintings. And they are indeed capable of taking away some of these valuable items. However, even if these tycoons can afford to take these things with them, they still cannot take away their entire collection, because even they can. Compromises must also be made in the face of the great crisis of human extinction, so what each of them can take away may be less than one-third or even one-fifth of their collection.

for this kind of thing. Are these big guys out of ideas? of course not. Therefore, when they heard that a lot of space could be freed up, these people immediately became excited.

In fact, what they don't know is that the space that can be saved on these spacecraft is actually much larger than they imagined.

Although these immigration ships currently being built by various countries around the world generally use super electromagnetic engines and propellers left behind by aliens. But when taking off, human rocket boosting technology is still needed to help launch. Some people may know how deceptive rocket boosting technology is. When satellites are launched, everyone can see how big those rockets are, but how big are those rockets? A rocket is dozens of stories high, the satellite only occupies one percent of the volume, and the rest of the space is basically filled with fuel tanks.

If the immigrant ship can enter space without relying on its own power, that means that not only can we reduce the size of the fuel tank, but we can even eliminate the installation of rocket boosting equipment at all and directly eliminate this part.

If this is done, it means that the current immigration ship can maintain its original performance without losing one-third of its volume. What is the concept of removing one-third of the volume of a spaceship? What is saved is not only the size but also the weight. This means that the construction cost and construction period of the new immigration ship will be greatly shortened, while the performance will be slightly improved. And if the volume is not reduced, then the extra one-third of the internal space can be used to store two more sets of auxiliary thrusters or bring more people, or it would be good to prepare more spare parts.

I don't plan to introduce these specific situations to them here. Anyway, they will definitely ask about it themselves in the future. Of course, this kind of modification can only be done to the spaceships that have not yet been completed. If the completed immigration ships are reworked, it will delay time. It is better to build more new ships if we have that time.

In fact, I personally think that it is not bad to retain some immigration ships with large propellers. The output power of the super electromagnetic engine we currently use is actually very small. It has no problem with long-term acceleration and stable endurance in space, but its explosive power is not enough. In the event of an emergency, it is difficult to correct the trajectory of the hull. The output power of those engines removed from the alien ruins is quite good, but unfortunately there are not enough of them, and they were originally thrusters for small spacecrafts, but we installed them on large spacecrafts, which is like a small horse pulling a big cart. , even if the thrust is very large, it is still relative to the original volume. It's still a bit insufficient for a large spaceship.

Although mankind's own rocket thrusters have many shortcomings, at least one thing is good, and that is high explosive power. Since rocket boost is no longer needed when launching a spacecraft, the fuel can be reserved for emergency use.

Of course, only these old immigrant ships can do emergency evasion, and newly built ones probably won't have this chance. But I'm not worried about that. Because according to the immigration plan, the population should become smaller and smaller during the immigration process.

According to the immigration plan, all people taken away after the immigration begins will enter the dormant cabin, and then their minds will be connected to the game world of "Zero" to survive and reproduce in it. At that time, the offline function of ordinary accounts will be cancelled, and everyone will stay in the game forever. If two people fall in love in the game and want to have children. Then the extractor in the dormant cabin outside will extract the germ cells from the two people respectively, and then the automatic equipment will complete the in vitro fertilization. After the embryos are stable, they will be re-implanted into the mother's body. During this period, the mother's body will be moved into a sleeping chamber dedicated to pregnant women. This sleeping chamber is larger and has a lot of corresponding equipment specially prepared for pregnant women and fetuses. For example, equipment that can provide prenatal education to the fetus and equipment that assists in delivery.

During the pregnancy of this fetus, the female player in the game will have a synchronization effect, which means that the game characters will have real reactions in sync with the outside world, such as pregnancy reactions such as morning sickness and abdominal pain. When the fetus is delivered in real life, it will also happen simultaneously in the game. After delivery is completed, the fetus will stay with the mother in a sleeping chamber dedicated to pregnant women for one month. During this period, the dedicated sleeping cabin will provide professional-level automatic care for fetuses and pregnant women. Moreover, the biggest difference between this sleeping cabin and ordinary sleeping cabins will also be reflected, that is, this sleeping cabin can provide pregnant women with Access the game with your fetus. A general hibernation cabin can only allow one person to access the game.

After one month, the fetus and mother will be removed from the maternal sleep chamber, the mother's body will return to the previous ordinary chamber, and the baby will be sent to a special sleep chamber for infants and young children. He or she will remain in the infant sleep chamber until the baby reaches three years old. The game is connected to the special sleeping cabin and will not be transferred to the ordinary cabin until the age of three. Of course, people in the game cannot feel the transformation of these dormant cabins. The state in the game will be just like in reality, directly giving birth to a child and then slowly raising the child. This process will not change. .

This entire process can ensure the normal reproduction of humans, but according to the plan, after immigration begins, humans will implement a comprehensive family planning policy. Because the number of sleeping cabins is already constant when taking off, there is no way to build more sleeping cabins on the way. Even if you bring a small amount of spare ones, you must consider the possibility of damage to the sleeping cabins. Therefore, the population must be controlled, otherwise it will be troublesome if there is no sleeping chamber after the newborn is born.

These immigration ships are designed based on the fact that human beings are always in a dormant state. If someone leaves the dormant state, it means that his consumption will exceed that of a normal person, because after being offline, a person cannot lie still all the time, and once the muscles are activated The energy consumed is definitely much more than in the dormant state. Moreover, people who wake up need more space, and there is not so much space on the spacecraft. What's even more dangerous is if someone here does something that endangers the safety of the spacecraft out of boredom or some motivation, it would be even worse. If one person loses his mind, tens of thousands of people may be buried with him in a boat. No one can bear this kind of loss.

Therefore, the simplest and most practical method is to control birth control.

In fact, the birth rate in European countries has never been very high, and the probability of unintended pregnancy will be reduced to zero after immigration begins, because as long as you do not apply for childbirth, the system will not help you collect germ cells to create embryos, just in the game In terms of love, it should actually be called "divine love". No matter how much you do this kind of thing, you won't have children.

Because those countries with the ability to build large numbers of immigration ships are developed countries, those countries with terrifying birth rates cannot actually leave many people. The birth rate of the population in developed countries is already low. As long as some policy inclinations are made in the game, a couple is required You only have one child. If you want to have more children, you need to spend money or do difficult tasks in the game. Anyway, set some levels and find ways to limit the second child. In this case, every two adults will only produce one offspring, so the population will become smaller and smaller from generation to generation.

Of course, we will not let the number of humans drop below the warning line, but eventually we will control the population on the immigrant ship to about one-tenth of what it was when it took off.

It is humanitarian to take everyone with you when the spacecraft takes off, and population control after takeoff is a necessary action. Moreover, the final population standard of one tenth is also a calculated conclusion.

Since the entire immigration process may take thousands of years, various problems are bound to occur on our immigration ships during this period. It was definitely not a big deal when it first took off, but after hundreds of thousands of years, the rate of equipment aging and damage on the immigration ship must be very high.

In space we have no way to build new equipment to replace it, so what we can do is - tear down the east wall to repair the west wall.

As the immigrant population declines, we can keep some of the equipment in reserve. Dismantle the replaced damaged equipment and keep the usable parts to repair other damaged equipment. If you repair it in this way, the equipment will definitely last longer. Moreover, when necessary, we will even dismantle part of the spacecraft to repair the damaged spacecraft. Anyway, this kind of thing must exist during the entire voyage, and it can be expected that when the fleet takes off and when it arrives at the destination in the future, the number will definitely differ greatly. If all these ships are full by then, then we will have to face the multiple-choice question of giving up a certain group of people. If we don’t want to make this choice, we can only plan our children in advance. In this way, when the equipment or spaceships are damaged and some spaceships need to be abandoned, we can concentrate the population and then dismantle the unoccupied empty ships. Wouldn't this be much more calm?

As long as family planning is implemented, the population will actually decline very quickly. After a few hundred years, most spaceships should still have no problems, but the population must have been reduced a lot. By then, those spaceships with extra rocket thrusters can be used By hitting it and using it, we can even get a second acceleration to allow the fleet to reach its destination faster. It can be said that these are all foreseeable things.

Listening to the beautiful blueprint I described, the tycoons were all very excited, and they were all thinking about what they could do when the time came.

After they calmed down a bit, I continued to speak and summarized the encounter. After that, these guys hurriedly went to find their people to discuss how to make good use of these technologies. As for me, I came to these pilgrims again, because they still had things to discuss with me in detail.

The previous spiritual network connection only transmitted things like knowledge and memory. Ideas still needed to be communicated, and there was no way to copy this. (To be continued ~^~)
