The construction of a fully enclosed ecosystem is actually nothing, and it has long been proven in practice. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

This is the space debris that was created by Xiao Wentian himself and has served as the base of the Jade Family for more than a thousand years.

In order to gain the trust of Queen Kangsheng, Yu Hongxing gave a detailed account of the inner workings of this space debris.

Of course, this is not to say that the technology used in this space debris can be used to transform the fugitive planet, at least not the core technology.

In the space debris of the Jade family, all the energy comes from the original energy, and the space debris itself also relies on the original energy to maintain stability. Because this space debris is in the Southern Alpha Galaxy, it can obtain enough original energy from the outside world, so it can exist stably for a long time.

Obviously, herein lies the problem.

According to Yu Hongxing, it can only be affirmed that if there is enough original energy in the star system, it will be able to obtain enough original energy. But outside the star system, there may not be enough primordial energy. At least according to the theory of Primal Energy, in the vast universe outside the star system, the density of Primal Energy is so low that it cannot be collected, so as long as it leaves the star system, the power equipment related to Primal Energy will lose its value. At least in theory, devices like the Primordial Converter don't work outside of a stellar system. Human scientists have confirmed this at the end of the Second Age, that is, the fugitive spacecraft that sent humans and other civilizations to the Southern Alpha system at that time carried the energy necessary for a slowdown, that is, the protocrystal, and the ecosystem of the fugitive spacecraft was maintained by ordinary nuclear energy. As a result, the escape ship loses its usefulness after reaching the Southern Alpha System and completing its deceleration.

Obviously, the amount of energy required to slow down a fugitive planet is definitely much greater than that of an escape ship.

What's more, it is impossible for the escape planet to be completely closed, and a lot of energy will definitely be leaked during the escape journey that lasts for tens of thousands of years.

As for creating a suitable ecological environment inside the fugitive planet, as long as there is enough energy, it is not a problem.

You must know that the space debris of the Yu family has been stable for thousands of years, and if there is no external influence, it can still exist stably. Theoretically, this space debris has a lifespan comparable to that of the Southern Alpha Galaxy, and will remain there until the destruction of the Southern Alpha Galaxy.

In other words, the Jade family has mastered, or can use, research on space debris to obtain the technology needed to create a long-term stable ecosystem.

The premise is that the energy supply must be assured.

Because the original energy is unreliable, the only thing left is nuclear energy, and it is fusion nuclear energy.

Obviously, after going around in circles, the question is back to energy.

Although hydrogen is the most widespread source of fusion nuclei in the universe, accounting for more than 99% of any galaxy, most of it is found in the main sequence stars of the star system, and the reserves on other celestial bodies are not sufficient. Even some giant planets contain no more than one percent of the hydrogen in their star system.

Obviously, if you want to get enough light elements, you have to take the main sequence star.

As for the storage of hydrogen, the problem is not very big, a large enough space debris will do. If proper pre-treatment is carried out, such as using a large enough pressure to allow the hydrogen to exist in a solid state, it is possible to store enough hydrogen in a space reservoir.

The real problem is that there is simply too much hydrogen needed.

According to Yu Hongxing's calculations, if the destination of the escape is a nearby star system, such as the beta galaxy about 30,000 light-years away, then the energy required for an escaped planet to accelerate, slow down, and stabilize the ecosystem for 30,000 years is equivalent to the energy consumed by a yellow dwarf-level main-sequence star to burn stably for one billion years. Even if acceleration is not taken into account, that is, the use of the original to accelerate the fleeing planet to the speed of light will only reduce the energy consumed by about half, that is, the energy consumed by a yellow dwarf star to burn stably for 500 million years. What is this concept? This is equivalent to one hundredth of the total mass of an ordinary yellow dwarf, which is about millions of times the total mass of the fugitive planet. If you get so much hydrogen from the main-sequence star in a relatively short period of time, it will inevitably collapse and destroy the main-sequence star.

Actually, this is still the ideal situation.

The conditions of the beta galaxy are very bad, the central black hole occupies 99% of the total mass of the entire star system, less than 100 million star systems have been detected, and less than 1/10,000 of the main sequence stars have enough mass to provide enough light and heat for the surrounding planets. In other words, even if they successfully reach the Beta Galaxy, civilizations such as humans and the Polar Race will not be able to settle here.

In terms of total resources, the ideal star system is the Segma system, which is about 150,000 light-years away.

It's a star system similar to the Milky Way, with a central black hole and about a billion star systems, and many of them have the right mass for their main sequence stars. If they can make it to the Segma system, humans and the Arctic may be able to find a suitable home here.

Provided, of course, that the situation in the Segma system is exactly the same as observed.

Don't forget, the distance of 100,000 light-years means that what we are observing now is what we saw in the Segma system 100,000 years ago.

Obviously, 100,000 years is too long.

This problem is not only in the Segma system, but also in all star systems. Put simply, no one can make an accurate judgment about the target star system based on what has been observed so far, not even the closest beta galaxy. If the civilization in the destination star system has grown and mastered the original energy, and even led to the outbreak of an all-out war that is enough to lead to the complete destruction of the star system, then after reaching the destination star system, human beings and civilizations such as the Polar Race will have to continue to flee. As a result, no one knows where to flee, where to go, or when to end it.

Whether it is 30,000 years or 100,000 years, it is an optimistic and conservative estimate.

In addition, after reaching the destination star system, it is necessary to slow down the fleeing planet, at least some of the fleeing planets, so as to confirm whether the destination star system is suitable for humans and the Polar Realm to stay and settle. In this way, it is necessary for the fugitive planet to take enough energy with it when it sets out.

In fact, in the absence of a certain destination, it is impossible to determine how long the escape will last.

Although Yu Hongxing has made a guarantee that the fully enclosed ecosystem based on space debris can exist stably, as long as it is properly maintained, let alone 100,000 years, even if it is a billion years, the longer it is maintained, the more energy is needed.

To put it simply, you have to prepare for the worst.

Ideally, you would take a main-sequence star that can survive for billions of years, and use the original to speed up the fleeing planet when you set off.

Obviously, the problem came back again, that is, at the beginning of the escape, the main sequence star of the star system where the fleeing planet was located.

This is not an easy decision, as it means that all the celestial bodies in the system will be completely destroyed, except for the fleeing planet.

Destroying an entire galaxy for the sake of one planet?

Obviously, how to get the population to accept it is a huge problem that cannot be solved by technology.

"Actually, that's the main purpose of my here." Yu Minghui took over the topic and said, "We can't wait until after the disaster to start fleeing, a lot of work has to be done in advance. In the worst-case scenario, we would have to spend at least thirty years moving people and stockpiling energy for the escape during that time. Regardless, it takes too much energy to accelerate the fugitive planet to the speed of light. Even if we have the holy artifact provided by Yang Yi, it needs to be activated in advance, and it is impossible to make it reach the speed of light in a short period of time, such as before the fleeing planet flies out of the star system where it is located. In this way, we will inevitably destroy the main-order star of the galaxy where the fleeing planet is located before then. ”

Queen Kangsheng nodded, indicating that she understood what Yu Minghui meant.

"My opinion is that the Human Federation and the Extreme Realm Race can't get too close." Yu Minghui didn't bend anymore. "Although we are allies now, and this relationship will be maintained until after the war is over. Although under Yang Yi's command, including the Human Federation and the Extreme Realm Race, all the civilizations in the Southern Alpha System will be unified, but judging from the current situation, there is no need for this for the time being. ”

"You mean ......"

"To put it simply, maintaining a state of war through confrontation can solve a lot of problems. For example, the centralization of power can be strengthened through the mechanism of warfare to ensure that the various projects surrounding the escape can be carried out smoothly. Of course, I can explain the unexplainable things with the need for war. ”

Queen Kangsheng was slightly stunned, and her brows locked together.

"Of course, this is only superficially at war. Privately, we will maintain contacts in the field of science and technology and share all the results of scientific research. But in other respects, there must be restrictions on exchanges, at least not to make the population think that those in power are pitted against each other for their own interests. In order to ensure that the distribution of resources is as fair as possible, that is, to ensure that we all have enough resources for us, and for those civilizations that depend on us, to complete the preparation of the flight, we need to redraw our sphere of influence before the war is over. As for the specific division method, it can be negotiated by the personnel we have arranged, and it is generally guaranteed that the civilization in the respective spheres of influence is proportional to the resources. ”

"The problem is, it's not going to be sustainable."

"We don't plan to last long, after all, we only have a hundred years."

Queen Kangsheng let out a long sigh and said, "In other words, we only need to remain opposed for this hundred years. Wait until the escape begins......"

"Actually, choosing to flee is only the worst outcome." Yu Minghui paused slightly before saying, "If Yang Yi succeeds, we don't need to take this step." The things we are discussing now are actually tentative. What exactly should be done will not be confirmed until Yang Yi returns. Either way, our purpose is to survive the impending catastrophe and fight for our common future. ”
