In the Earth Age, there was a very famous super hydropower station. In order to build it, people once cut off one of the world's largest rivers and formed a vast lake covering more than a thousand square kilometers.
The amount of water stored in this lake is about 40 billion cubic meters, which means the total mass of water stored is about 40 billion tons.
And this number is only one 250th of the mass that people need to take away from the Lakai 9352 galaxy at this moment.
That is to say, for this interstellar voyage, people need to transport all the water in about 250 huge reservoirs from one star system to another star system 12.2 light-years away.
Even for human civilization at this moment, this is an extremely huge project. It is precisely because of this, and because it has long been known that it is huge, that the human civilization government has specially reserved a century for this project.
It took more than 200 million people a century of struggle to complete this project.
There are three key points in this project. The first important point is naturally the reserve of antimatter energy.
In space, nothing is more important than energy. In a sense, it is even more important than the millions of types of materials.
The reason is simple. Materials can be reused. As long as there is enough energy, most materials can be continuously recycled. For example, human breathing changes oxygen into carbon dioxide, and at the cost of a certain amount of energy, carbon dioxide can also be reduced back to oxygen and carbon.
Faced with a mass of up to ten trillion tons, a rough estimate would require at least 600 million tons of antimatter energy. Allow for redundancy and then double it, it will reach about 1.4 billion tons.
If so much antimatter energy reacts completely with positive matter of corresponding mass, the energy released will be equivalent to the energy released by a huge star like the sun in 700 seconds, which is equivalent to the energy released by the earth in 700 seconds. The total amount of solar energy received over approximately 50,000 years.
Fifty thousand years ago, human civilization was still consuming hair and blood. From that moment until now, all the energy the earth has received from the sun, which has driven wind, rain, thunder and lightning, driven all things to grow, driven rivers to run, and driven the melting of ice and snow in these 50,000 years, is only enough for this one voyage. use.
In order to prepare up to 1.4 billion tons of antimatter, approximately 11.7 billion tons of hydrogen will be required to be completely converted into energy, and a full 1.67 trillion tons of fusion fuel will be required to participate in fusion.
This requires the simultaneous participation of numerous fusion power stations with highly automated capabilities to be completed in just 100 years.
As a result, a considerable part of the construction power saved by canceling many other projects was invested in the tasks of fusion power stations and antimatter preparation factories.
The second important point is the manufacturing of interstellar spacecraft.
Building a simple passenger and cargo transport spaceship is much simpler and easier than building a battleship. After all, people don't need to consider mobility, weapon systems and a series of other things. But this time the spacecraft that needed to be built was too big.
A spaceship the size of the Voyage had never been built before.
Fortunately, during the process of repairing and maintaining the Voyage spacecraft, people have accumulated a lot of data, and they are still certain about building such a large spacecraft that is capable of interstellar navigation.
This is not to say that the current technology of human civilization is more advanced than the original deep space civilization - you know, the original deep space civilization lost almost 99% of the mass of the fleet for an interstellar voyage, leaving only the last bit surviving. Only then did they survive and reach the solar system.
Taken together, the current technological level of human civilization is still not as comprehensive as that of deep space civilization.
But the most critical point is that human civilization has solved one of the biggest pain points in interstellar navigation, which is the problem of large-scale preparation of antimatter energy. Solving this problem will almost solve 99% of the problems in interstellar navigation.
What deep space civilization cannot do, only human civilization can do.
At this moment, the comprehensive performance of the interstellar spacecraft built by people can reach about 60% of that of the Yuanhang spacecraft.
It’s just that the amount of work is too huge. But there is no way, just gather the power of the entire civilization and pile up manpower and material resources.
The third important point is the reserve of materials.
Water, salt, sugar, rice, wheat, various minerals of gold, silver, copper and iron, oxygen, carbon, etc., the list includes at least millions of different materials.
Compared with the first two tasks, this task is actually relatively easy. The most important human civilization now has the experience of an interstellar voyage. Most of them know what materials to carry during the voyage and what proportion of a certain type of materials to carry.
It's just more complicated and troublesome.
There is also no clever way to solve this problem, and we can still only rely on manpower and material resources to pile it up.
Under these three key points and three projects, the manpower and material resources saved by the previous contraction of civilization were all divided up in a snap before they could even be repaired.
Not only that, the manpower and material resources required for these three projects have also seriously eroded the resource share of the remaining projects. The most obvious example is that the market economy once again suffered a devastating blow at this stage. The entertainment industry, service industry, clothing, home textiles, tourism and other industries were almost completely wiped out. All practitioners were led to participate in these three industries. During this huge project, the entire society once again entered the era of planned economy.
In addition, in the scientific community, which also has extremely high strategic significance for civilization, except for some of the top scientists who can still obtain some resources for cutting-edge research, almost all the scientific research activities of other scholars have been forced to suspend.
The reason is simple. The human government can no longer provide enough resources to supply them at this moment.
The life of every scholar is precious. In order to cultivate them, civilization has spent huge resources and costs. However, it is a huge waste to waste their lives on work with little technical content.
Therefore, based on the principle of voluntariness, many scientific researchers have chosen to temporarily freeze their lives to wait for the situation of civilization to improve again.
This seems to be a kind of "deserting". While others are working hard and struggling, they are lying in the hibernation cabin, sleeping and lazy. In fact, these scientific researchers are indeed escaping. However, Zhao Changxing insisted on making this decision despite all opinions.
Zhao Changxing is a pragmatist. He believes that doing so is beneficial to civilization, and in fact it is beneficial. Then, as long as the values of civilization and the bottom line of morality are not involved, he will definitely do it and will not care about the "value of life." , "value" and other arguments that have no right answer.
At the same time, large-scale military exercises have also been completely stopped, and only small-scale military exercises and training aimed at "maintaining combat status" continue. Some of the backbone members of the military were also allowed to enter hibernation to temporarily freeze their lives. Most of the remaining soldiers were devoted to this "war".
Yes, these three projects are a war for human civilization. Certain tasks that require a high degree of organization and the participation of fast mobile forces are just right for soldiers to complete.
For the soldiers, this also has a function similar to a military exercise, and they will not forget all the skills they learned through hard training in the past.
Under this situation, the Lakai 9352 galaxy once again entered a busy state.
Waves of radio waves are flying through the vast space, and spaceships are shuttling back and forth. Huge amounts of materials like mountains and seas, accompanied by the ejection of electromagnetic railguns, are either shuttled between land and space, or between different planets. shuttle.
Under the "attack" of more than 100 million people, led by almost tens of billions of robots and automated machinery, even the landscapes of these three planets were changed.
The waste produced by hundreds of thousands of giant factories filled basins and canyons. Mountains rich in minerals that people desperately needed were flattened. The originally roughly flat plains were filled with ravines and depressions. Materials were transferred between different places on the planet's surface. The transfer has even had an impact on the planet's crust, indirectly causing volcanoes and earthquakes to become more frequent.
For these three planets, this can almost be called an earth-shaking change. But under people's intentional control, when observed from outside this galaxy, the galaxy still remains calm.
At least with the current level of technology and relevant scientific predictions, people cannot find any way to detect signs of such major changes taking place here from a distance of several light years.
During this century, many people reached the limit of their life span and eventually died. A small number of newborns are born naturally and enter this world.
After adding and subtracting, the population finally dropped to about 200 million as originally expected.
In this century, one after another interstellar spacecraft as huge as the Voyage spacecraft appeared in front of people's eyes. A huge amount of materials with a mass measured in trillions of tons gradually gathered into these spacecraft under the spray of the electromagnetic railgun.
One after another, space cities that originally had their own style, carried people's different life spans, and retained many people's memories were abandoned, and eventually lost all temperature and became as cold as interstellar meteorites. One after another, the huge factories that were roaring day and night and filled with people gradually stopped, returning the coldness and deathly silence to this world.
Human civilization is like a passing guest, only staying briefly in this galaxy for a life span of at least tens of billions of years. Now, it is time to leave.
