Starting from Zero

"The fourth technology is not a space technology in itself, but a technology for launching massive objects." I explained: "Everyone knows that launching spacecraft It is a very energy-consuming behavior. For example, it is quite difficult for us to launch some satellites weighing a few tons. In the age of the universe, the weight of many large space battleships may exceed 10,000 tons. This level of spaceship will also be very powerful. , But it is indeed very energy consuming to rely on its own power to break away from the surface of the planet. Therefore, some planets will specially set up some devices to help the large-tonnage spaceship take off."

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

"In fact, it is not a special device. It should be similar to an electromagnet. The difference is that this thing is directional emission and uses gravitational waves instead of magnetic fields."

"Gravitational waves?"

"Yes. To put it simply, a huge gravitational wave generating device is set on the surface, and then the spaceship that needs to enter space enters the upper area of ​​the device. When the device is activated Then an upward gravitational wave will be generated, and at the same time assisted by a special repulsion field, the spaceship can be sent directly into space without the spaceship's own engine starting at all.

This technology It is widely used on the creators’ planet. Its launch cost per unit mass is higher than that of a space elevator, but its own construction cost is very low, the construction difficulty is also very small, and the maintenance is simple. The most important point is that the orbital elevator can transport scattered pieces. Goods or small spaceships that can be loaded into containers can also be transported, but for some large spacecraft, orbital elevators are obviously inappropriate. This kind of device is just complementary to orbital elevators, which is very safe. High and very low-cost launch devices. The creators’ military launch systems are basically based on this, while rail elevators are more like civilian technology.

As far as our current situation is concerned, We simply don’t have enough technology to complete the rail elevator, and even if we have that technology, we don’t have that time. However, the structure of this launcher is very simple. According to my estimation, without affecting other construction projects, we can Complete at least thousands of this thing all over the world."

"So what's the use of this launcher?" A tycoon asked.

"There are many uses. For example, spaceship itself can go directly into space without consuming any fuel, which means that our spaceship can save some more fuel. In addition, because of this technology, we From now on, all immigrant ships built afterwards can be modified to reduce the size of the fuel tanks and free up some space for storing more dormant compartments. This way, more can be taken away without adding extra workload. People. Don’t you think this is a great thing? Even if the saved space is not used to install people, it’s a good choice to bring more resources and equipment. Don’t you want to put the antiques and famous calligraphy and paintings on Earth? Take everything away?"

Hearing my last words, the big guys obviously reacted differently.

Regardless of the level of social development, true equality between people is impossible. Although because of the great crisis of human extinction, all countries have been cruel this time, and the migrant ship should try to save space for manned use. However, even this does not mean that these tycoons will leave empty-handed when the time comes. Many of them have actually planned to leave with some jewelry, antiques, calligraphy and painting, and they are indeed capable of taking away some of these valuable items. However, even if these tycoons have the ability to bring these things, they still cannot take away all of their collections, because even they have to make compromises in the face of the great crisis of human extinction, so each of them can bring them. The things left may not reach one third or even one-fifth of their collection.

For this kind of thing, do these big guys have no idea? of course not. So, when they heard that a lot of space could be freed up, this group of people immediately got their enthusiasm.

What they don't know is that the space saved on these spaceships is actually much larger than they thought.

Although these immigrant ships currently being built by various countries in the world generally use super-electromagnetic engines and those left behind by aliens, they still need human rocket-assisted technology to help launch them when they take off. . Some people may know how bad the rocket boost technology is. Everyone can see how big those rockets are when launching satellites, but how big are those rockets? A rocket is a few 10th layer high, the satellite only occupies one percent of the volume, and the remaining space is basically fuel tanks.

If the immigration ship can enter space without relying on its own power, it means that we can not only reduce the volume of the fuel tank, or even completely eliminate the rocket booster equipment, and directly save this part.

If this is true, it means that the current immigration ship can maintain the original performance without removing the one third volume. A spaceship removes the one third volume. What is the concept? The savings are not only volume, but also weight. This means that the construction cost and construction period of the new type of immigration ship will be greatly shortened, but the performance will be slightly improved. And if the volume is not reduced, then the extra internal space of the one third can be filled with two sets of auxiliary propellers or more people, or it is good to prepare more spare parts.

I didn't plan to introduce them to the specific situation here, anyway, they will definitely ask themselves in the future. Of course, this kind of modification can only be done to the spaceship that has not been completed. If the completed immigration ships are reworked, it will delay time. It is better to build more new ships if you have that effort.

In fact, I personally feel that it is not bad to keep some of the immigration ships with large propellers. The output power of the super electromagnetic engine we currently use is actually very small. Long Time Acceleration and stable endurance in space are no problem, but the explosive power is not enough. It is difficult to correct the hull motion trajectory in case of an emergency. The output power of the engines removed from the alien relics is quite good, but unfortunately these things are not enough, and they were originally used for small spaceship propellers, and we installed them on the large-scale spaceship, which is a little small horse-drawn cart. The meaning of, even if the thrust of others is great, it is relative to the original volume, and it is still not enough for a large spaceship.

Although humans’ own rocket thrusters have many shortcomings, at least one is good, that is, they are very explosive. Since the rocket boost is not needed when launching the spaceship now, it is entirely possible to save the fuel for emergency use.

Of course, only these old immigrant ships can do emergency evasion, and the newly-built ones probably won't have this kind of opportunity. However, I am not worried about this, because according to the immigration plan, the population should become smaller and smaller during the immigration process.

According to the immigration plan, all the people who are taken away after the immigration begins will enter the dormant cabin, and then the minds of these people will be connected to the game world of "Zero", where they will survive and multiply. When the time comes, the offline function of ordinary accounts will be cancelled, and everyone will be left in the game forever. If two people love each other in the game and want a child, the extractor in the dormant cabin outside will extract germ cells from the two people separately, and then the in vitro fertilization will be completed by the automatic device, and the embryo will be re-implanted into the mother after the embryo is stable. During this period, the mother’s body will be moved into a dormant cabin dedicated to pregnant women. This dormant cabin is larger and has a lot of corresponding equipment specially prepared for pregnant women and fetuses, such as equipment that can teach the fetus and assist in childbirth.

In the process of gestation of this fetus, the female players in the game will have a synchronization effect, which means that the game characters will have real reactions synchronously with the outside, such as pregnancy reactions such as morning sickness and abdominal pain. When the actual fetus is delivered, the game will also be synchronized. When the delivery is completed, the fetus and mother will stay in the pregnant dormant cabin for one month. During this time, the dedicated dormant cabin will provide professional services to the fetus and pregnant women. Level of automatic care, and the biggest difference between this dormant cabin and the general dormant cabin will also be reflected, that is, this dormant cabin can allow pregnant women and fetuses to access the game at the same time, while the general dormant cabin can only allow One person accesses the game.

After waiting for a month, the fetus and mother will be removed from the pregnant dormant cabin, the mother will return to the previous normal cabin, and the baby will be sent to the infant dormant cabin until the baby grows up to three years old. (She) will connect to the game in the sleeping cabin for infants and young children, and will be transferred to the ordinary cabin after three years of age. Of course, the people in the game will not feel the transition of these dormant cabins. The state in the game will be like in reality. The child will be born directly, and then the child will be raised and grown up slowly. This process will not change. .

This whole set of procedures can ensure the normal reproduction of human beings, but according to the plan, after immigration begins, human beings will implement a comprehensive family planning policy. Because the number of dormant cabins is already constant during takeoff, there is no way to build more dormant cabins on the way. Even if you bring a small number of spares, you must take into account the damage of dormant cabins. Therefore, the population must be controlled, otherwise it will be troublesome if there is no dormant cabin after the newborn comes out.

These immigration ships are designed in accordance with human beings who have been in a dormant state. If someone leaves the dormant state, it means that his consumption will exceed the consumption of normal people, because people are impossible to lie down after they are offline. , And once the muscles are active, it consumes more energy than the dormant state. Moreover, people who wake up need more space, and there is not so much space on spaceship. What's more dangerous is that if someone in it does something jeopardizing the safety of the spaceship because of boredom or some motive, it's even worse. If one person becomes nervous, it may mean that tens of thousands of people will be buried in a boat. No one can bear this kind of loss.

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

The birth rate of European countries has not 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 a childbirth, the system will not help you collect germ cells for pregnancy. Embryos, if they are affectionate in the game, they should actually be said to be "spiritual friendship". No matter how much this kind of thing is done, there will be no children.

Because those who have the ability to build a large number of immigration ships are developed countries, those countries with scary birth rates can actually not leave a few people, and the birth rate of developed countries is inherently low, as long as you make some in the game The policy is inclined, requiring a couple to have only one child. If you want to have more births, you need to spend money to buy it, or you have to do difficult tasks in the game. Anyway, set some levels and find a way to limit the second child. In this case, only one offspring will be produced for every two adults, so that the population will become smaller and smaller as it multiplies from generation to generation.

Of course, we will not let the number of humans fall below the warning line, but in the end we will control the population on the immigration ship to about one-tenth of the time when it takes off.

When spaceship takes off, try to bring everyone with you. This is out of humanitarianism, 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 will inevitably occur on our immigration ship during this period. There must be nothing at worst when it first took off, but after hundreds of thousands of years, the proportion of aging and damage to the equipment on the immigration ship must be very high.

In space, we have no way to build new equipment to replace, so what we can do is to demolish the east wall and make up the west wall.

As the immigrant population declines, we can make part of the equipment become backup equipment. Disassemble the replaced damaged equipment and keep the usable parts for repairing other damaged equipment. In this way, if repaired, the equipment support time will definitely be longer. Moreover, when necessary, we will even dismantle part of the spaceship to repair the damaged spaceship. Anyway, this kind of thing must exist in the whole voyage, and it can be expected that when fleet takes off and when it arrives at the destination in the future, the number is absolutely different from the large section. If when the time comes, these boats are all full, then we have to face the multiple choice question of choosing to abandon a certain group of people, and we don’t want to make this choice, we have to plan our family in advance. In this way, when the equipment or the spaceship is damaged and some spaceships need to be abandoned, we can concentrate the population and then tear down the empty boats with no one. Isn't this more calm?

As long as the family planning is implemented, the population decline is actually very fast. After a few hundred years, most of the spaceship should be no problem, but the population has definitely decreased a lot. When the time comes, those who have The spaceship of the extra rocket booster can be hit and used, and we can even have a second acceleration to make fleet reach its destination faster. It can be said that this is something that can be foreseen.

Listening to the beautiful blueprint I have drawn, the tycoons are all very excited. They are all there calculating when the time comes and what to do.

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

The previous heart-spirit net network connection only transmits things like knowledge and memory. Ideas still need to be exchanged. There is no way to copy this stuff.
