Yu Hongxing's idea is bold and highly feasible. It is at least more realistic than building billions of fugitive spacecraft in a short period of time, but it is also very difficult to implement. Not only are technical problems, there are also some non-technical problems that cannot be solved with technology.
To transform a planet-level celestial body into a fugitive spacecraft is a completely enclosed world to be precise. Although there are no insurmountable obstacles at the technical level, it takes enough time and the huge amount of engineering needs to be invested enough. Labor force.
Obviously, the renovation project cannot be completed before the start of the flight.
To put it simply, the transformed planet is actually a super fugitive spacecraft, which can carry tens of thousands of times as many passengers as the fugitive spacecraft. Living on a planet with a diameter of 5,000 kilometers and completely hollowing out the interior, leaving a shell with a thickness of about 20 kilometers, the surface area of the inside of the shell is equivalent to the surface area of the planet, under the premise of satisfying the basic living environment , Can accommodate up to 10 billion residents.
However, just one planet is obviously not enough.
If it were just a human federation, it would probably need a thousand such planets. Counting the Extreme Realm Clan, about 5,000 such planets are needed. If all other civilizations in the Southern Alpha Galaxy are taken into consideration, at least one hundred thousand such planets are needed. Even if certain civilizations do not have very high requirements on the living environment, or can reduce their survival requirements during their flight, at least 50,000 such planets are needed.
Of course, 50,000 planets is not too much.
In the Southern Alpha Galaxy, the diameter is about 5,000 kilometers, there are more than 10 billion planets with sufficient resources, and more than 90% of them have no permanent residents.
The problem is that the amount of engineering needed to transform 50,000 planets is not much less than the construction of a billion fugitive spacecraft.
In other words, if 50,000 planets can be transformed within 100 years, one billion fugitive spacecraft can be built, and from the perspective of the probability of success, one billion fugitive spacecraft must be much higher than 50,000 planets. . If it is just to preserve the seeds of civilization, then an escape ship should be built.
In fact, this is also one of the main reasons why human scientists decided to build a fugitive spacecraft at the end of the Second Age.
Yu Hongxing proposed this plan only because the current situation is different from the end of the second era, at least there is no problem between the two camps.
Don't forget that at the end of the second era, only a few human scientists advocated fleeing, and most human scientists put their hopes on the aerospace technology of interstellar systems based on the central black hole. Although scientists who advocated fleeing got the chance, the resources they got were extremely limited. More importantly, no one hoped to save everyone at the time, but only hoped to preserve the seeds of civilization.
Obviously, the current situation is just the opposite.
Although the war is not over, the war that has lasted for hundreds of years will soon come to an end after the Extreme Realm Race joined the war as an ally of the Human Federation. Yang Yi's goal is to save everyone, at least with this as the fundamental goal, there is no other feasible means. As for the other method that Yang Yi personally searched for, because it did not take up too much resources, the impact on the escape operation was extremely limited.
That's why Yu Hongxing proposed this plan.
However, the problem is also prominent.
Because the transformation work cannot be completed before the start of the escape, Yu Hongxing proposed that the transformation of the planet should be arranged after the start of the escape, and only the preliminary preparations need to be completed before that, such as setting up an industrial system for transformation services on the planet, and building an industrial system based on Original energy, an ecosystem that can provide a suitable living environment and working environment for all residents on the planet before the completion of the transformation.
In addition, it is necessary to hoard resources that are indispensable for transformation on some planets and are not available on this planet.
Although this is also a huge project that requires a lot of resources to be invested, compared with the transformation of the planet, this early investment is not worth mentioning. Not to mention the extreme races, even the human federation can complete the pre-transformation preparations on 5,000 planets that meet their own needs within about ten years. If it is an extreme race, it only takes 20 years at most to complete the preparation work on 50,000 planets.
Obviously, compared to building a fugitive spacecraft, the preparatory work required to transform the planet is much less.
Although this is just preliminary preparations and does not mean post-modification, and the amount of renovation works is still amazing, but according to Yu Hongxing's plan, the renovation will be carried out after the start of the escape, and at that time, I am afraid that no one will make a huge renovation. The project is questioned. Whether it is for themselves, for their own nation, or for other civilizations, everyone will go all out to participate in the transformation work.
In fact, there is a problem involved here, that is, the attitudes of various civilizations and many individuals of each civilization to escape.
There is no doubt that this is also the most serious problem.
In a sense, the Yu family's rejection of the plan to build a fugitive spacecraft is directly related to this.
Even if the people in power of the Yujia family, as well as Queen Kang Sheng and other extreme tribes firmly believe in Yang Yi, they may not be able to persuade others to believe in Yang Yi's prophecy. As for the signs discovered by scientists such as Yu Hongxing, they are only signs at best, and they cannot prove that a disaster is imminent.
Obviously, this problem still exists in the preliminary preparations for planetary transformation.
To put it bluntly, it is not a trivial matter to just build a complete industrial system on at least 50,000 planets and reserve enough supplies in advance. If there is enough time in peacetime, the problem is not too big. After all, both the extreme state race and the human federation have strong industrial productivity, can provide enough industrial products, and the resources are not too small. The problem is that the war is not over yet, even after the war is over, post-war reconstruction must be carried out. At this time, limited resources and industrial productivity are drawn to do things that have nothing to do with post-war reconstruction. It is difficult to get the support of the people, or even This will arouse public doubts and dissatisfaction with the power authorities.
In fact, this is also the key to Yu Hongxing's belief that reforms should be carried out after the start of the escape.
For this reason, Yu Hongxing put forward a set of more detailed plans, to be precise, a plan with a clear time point but no specific content. To put it simply, it is best to complete the preliminary preparations within 50 years, not more than 70 years at most, and to focus on technical preparations in the first 20 years. After the completion of the post-war reconstruction of various civilizations, the focus will be on the construction of the industrial system and the reserve of resources. The main purpose of doing this is to reduce the impact on the people in the early stage, so as to gain the approval and support of the people. In addition, the preliminary technical research and subsequent infrastructure construction overlapped with post-war reconstruction, so that post-war reconstruction can be used to keep secrets, avoid letting the public know the news related to the disaster prematurely, and ensure that all civilizations can remain stable. .
However, if you strictly follow the time points proposed by Yu Hongxing, it is indeed very difficult. Even if the time is relaxed to 70 years, the preliminary preparations may not be completed in time. As for continuing to relax the time limit, it is unlikely. After all, it will take enough time to transfer the people of various civilizations to the escaped planet. Relative to the number of transferred personnel, thirty years is not sufficient.
Of course, this is only difficult, and it is difficult to overcome.
In Yu Hongxing's words, as long as we make full use of post-war reconstruction, that is, use the special circumstances of post-war reconstruction to mobilize more resources and manpower, the problem of completing the preliminary preparations is not very big. For example, a comprehensive survey of those fugitive planets can be done in the name of post-war reconstruction. Since the post-war reconstruction is the responsibility of the authority in charge, the authority will also determine the duration of post-war reconstruction and the resources used. Even if the people have questions about this, it can be explained by post-war reconstruction, at least in the short term, it will not arouse public disgust. Obviously, compared to this war that has lasted for hundreds of years and spread to the entire southern Alpha galaxy, decades are not long.
However, there is a problem that cannot be concealed by post-war reconstruction.
This is, at the beginning of the flight, the main sequence star of the star system where the fugitive planet is located must be destroyed, so as to free the fugitive planet from the gravitational restraint of the main sequence star. Although theoretically speaking, this step will only be taken when the signs are obvious enough or it has been able to prove that the disaster is about to happen, but it must be before the disaster, and it is certainly impossible to make a reasonable explanation to the people immediately. From the beginning of the flight to disaster, there is at least a few years or even decades of interval. During this period, the people’s attitude towards the flight, or the trust in those in power, will have a decisive effect, and a situation may arise. Serious consequences such as loss of control.
In addition, even if this interval is shortened as much as possible, another problem cannot be avoided. It is necessary to obtain enough fusion elements from the main sequence star before fleeing, which will inevitably have an impact on the main sequence star, and may even cause it. The main sequence star is completely destroyed.
Obviously, even Queen Kang Sheng could not make a reasonable explanation to the people of the extreme race.
Don't forget, as early as the second era, all civilizations gave up nuclear energy and turned to use primal energy. After that, the scientific system of all civilizations was built on the original energy. Although the war has caused tremendous damage, no civilization has reason to go back, let alone destroy the main sequence stars of a star system in order to obtain fusion materials that are widespread in the universe and are not of great value.
It can be said that this retrogressive approach will inevitably arouse public suspicion, and it may have unexpected effects.
Simply put, the situation is the most dangerous during the period after the start of the flight.
As for how to get through this dangerous period, Yu Hongxing did not propose any solution. After all, he is a scientist and is not responsible for solving problems outside of science.
Of course, in Yu Hongxing's words, after the start of the flight, especially after the disaster has been confirmed, all the problems are no longer problems. What needs to be faced then is how to get as many people as possible to reach the destination alive during the long escape journey.
For this reason, the Yu family gave a proof enough to convince Queen Kang Sheng.
