Building a fully enclosed ecosystem is actually nothing at all, and it has long been proven in practice.
This is the space debris that was created by Xiao Wentian himself and has been serving as the Yujia base for more than a thousand years.
In order to gain the trust of Queen Kang Sheng, Yu Hongxing introduced in detail the internal operation of this space debris.
Of course, it does not mean that the technology used in this space debris can be used to transform the fugitive planet, at least the core technology is not available.
In Yujia’s space debris, 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 can obtain enough primal energy from the outside world in the Southern Alpha Galaxy, it can exist stably for a long time.
Obviously, the problem lies here.
According to Yu Hongxing, it is only certain that if there is enough primal energy in the star system, enough primal energy can be obtained. But outside the star system, there may not be enough primal energy. At least according to the theory of primordial energy, in the vast universe beyond the star system, the density of primordial energy is so low that it cannot be collected. Therefore, as long as you leave the star system, the power equipment related to primordial energy will lose value. At least in theory, devices such as prime energy converters do not work properly outside of the stellar system. This has been confirmed by human scientists at the end of the second era, that is, the fugitive spacecraft that sent human civilizations to the Southern Alpha galaxy at that time carried the energy necessary for a deceleration, that is, the original crystal, and maintained the fugitive spacecraft’s ecosystem. It is ordinary nuclear energy. It is also true that the fugitive spacecraft lost its usefulness after reaching the Southern Alpha Galaxy and completing its deceleration.
Obviously, the energy required to slow down the fugitive planet must be much greater than that of the fugitive spacecraft.
More importantly, the escape planet cannot be completely enclosed, and a lot of energy will definitely be leaked during the tens of thousands of years of escape journey.
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 in the Yu Family has existed stably for thousands of years, and if there is no external influence, it can still exist stably. Theoretically, the life span of this space debris is comparable to that of the Southern Alpha Galaxy, and it will exist until the Southern Alpha Galaxy is destroyed.
In other words, Yujia has already mastered or is able to obtain the technology needed to create a long-term stable ecosystem through research on space debris.
The premise is that energy supply must be guaranteed.
Because the original energy is unreliable, only nuclear energy is left, and it is fusion nuclear energy.
Obviously, after going around, the problem returned to energy.
Although the raw material of fusion nuclei, the hydrogen element, is the most widespread in the universe, the proportion of hydrogen in any star system exceeds 99%, but most of the hydrogen is present in the main sequence of the star system. Among the stars, the reserves on other celestial bodies are not sufficient. Even some giant planets with huge volumes do not contain more than one percent of the hydrogen in the star system.
Obviously, if you want to get enough light elements, you have to take the main sequence star.
As for storing hydrogen, the problem is not that big, just a large enough space debris. If proper pre-treatment is carried out, such as large enough pressure to allow hydrogen to exist in a solid state, enough hydrogen can be stored in the space storage.
The real problem is that too much hydrogen is needed.
According to Yu Hongxing’s calculations, if the escape destination is a nearby star system, such as the Beta galaxy about 30,000 light years away, then an escape planet will accelerate, decelerate, and stabilize the ecosystem for 30,000 years. The energy required is equivalent to the energy consumed by a yellow dwarf-class main sequence star that burns steadily for one billion years. Even if acceleration is not considered, that is, using the original to accelerate the fugitive planet to the speed of light, it will only reduce the energy consumed by about half, that is, it requires a yellow dwarf star to stably burn the energy consumed for 500 million years. What concept is this? This is equivalent to one percent of the total mass of an ordinary yellow dwarf star, which is about millions of times the total mass of the fugitive planet. If so much hydrogen is obtained from the main sequence star in a relatively short period of time, the main sequence star will inevitably collapse and destroy.
In fact, this is still the most 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. There are less than 100 million star systems that have been detected, and less than one in ten thousand main sequence stars have Sufficient mass can 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 extreme races will not be able to settle here.
In terms of total resources, the ideal star system is the Sagema galaxy, which is about 150,000 light-years away.
This is a star system similar to the Milky Way, with a central black hole and about one billion star systems, and the main sequence stars of many star systems have appropriate masses. If they can successfully reach the Segma galaxy, humans and extreme races may be able to find a suitable home here.
Of course, the premise is that the situation in the Segma Galaxy is exactly the same as observed.
Don't forget, the distance of one hundred thousand light-years means that what we are observing now is the sight of the Segema Galaxy one hundred thousand years ago.
Obviously, one hundred thousand years is too long.
This problem not only exists in the Segma galaxy, but also exists in all star systems. Simply put, no one can make an accurate judgment on the condition of the target star system based on the results currently observed, even in the nearest Beta galaxy. If the civilization in the target star system has developed and grown, mastered the original energy, and even caused an all-out war that could lead to the complete destruction of the star system, then after reaching the target star system, civilizations such as humans and the extreme races must continue to flee. . In this way, no one knows where the fleeing destination is, and there is no way to know what it is, or when the escape journey can be ended.
Whether it is 30,000 years or 100,000 years, it is an optimistic and conservative estimate.
In addition, after reaching the target star system, the fugitive planet must be decelerated, at least part of the fugitive planet must be decelerated, so as to confirm whether the target star system is suitable for humans and polar races to stay and settle. In this way, the fugitive planet must have enough energy when it sets off.
In fact, when the destination of the flight cannot be determined, it is also impossible to determine how long the flight 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 one hundred thousand years, even one billion years will be no problem, but the longer it will last. , The more energy is needed.
Simply put, we must prepare for the worst.
The most ideal situation is to bring a main sequence star that can be stable for billions of years, and use the original to accelerate the escaped planet when setting off.
Obviously, the problem has revolved around again, that is, at the beginning of the flight, the main sequence star of the star system where the fugitive planet is located has to be destroyed.
This is not a simple decision, because it means that all celestial bodies in the star system will be completely destroyed except for the fugitive planet.
Destroy the entire star system for one planet
Obviously, how to get people to accept is a huge problem that cannot be solved with technology.
"Actually, this is also the main purpose of my coming here." Yu Minghui took over the topic and said, "We can't wait until the disaster strikes to start fleeing. A lot of work must be done in advance. Starting from the worst case, we at least It takes thirty years to transfer personnel and reserve energy for the escape during this period. Anyway, it takes too much energy to accelerate the escaped planet to the speed of light. Even if we have the sacred artifact provided by Yang Yi, we need to activate it in advance. It is impossible for the fugitive planet to reach the speed of light in a short period of time, such as before it flies out of the star system where it is located. In this way, we will inevitably destroy the main sequence star of the star system where the fugitive planet is located before then."
Queen Kang Sheng nodded, expressing 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 make any further detours. "Although we are now allies, and this relationship will be maintained until the end of the war. Although under the command of Yang Yi, including the Human Federation and the Polar Race, all civilizations in the Southern Alpha Galaxy will be unified, but with Judging from the current situation, it is not necessary for the time being."
"You mean..."
"Simply put, through confrontation and maintaining a state of war, many problems can be solved. For example, the mechanism of war can be used to strengthen the centralization of power to ensure the smooth progress of various projects around escape. Of course, I can use the need for war to explain those that cannot be explained. Thing."
Queen Kang Sheng was taken aback for a moment, her brows frowned.
"Of course, this is only in a state of war on the surface. In private, we will maintain exchanges in the field of science and technology and share all scientific research results obtained. It is just that exchanges in other areas must be restricted, at least not to let the people think that those in power are for their own interests. They are opposed to each other. In order to ensure that the distribution of resources is as fair as possible, that is, to ensure that we have enough resources for us, and those civilizations that depend on us, to prepare for escape, we need to re-divide our sphere of influence before the end of the war. As for the specific division method, the personnel we arrange can be negotiated to generally ensure that the civilization within the respective sphere of influence is proportional to the resources."
"The problem is, this situation cannot be maintained."
"We have no plans to maintain it for long, after all, we only have a hundred years."
Queen Kang Sheng exhaled and said: "In other words, we only need to maintain opposition for this hundred years. Wait until the start of the escape..."
"Actually, choosing to flee is only the worst result." Yu Minghui paused for a while before saying, "If Yang Yi succeeds, we don't need to take this step. The things we are discussing are actually temporary. It is decided. What should be done will not be confirmed until Yang Yi comes back. Anyway, our goal is to escape the coming disaster and fight for our common future."
