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 government of human civilization has specially reserved a century for this project.
It took more than 200 million people a century of hard work to complete this project.
This project contains three key points. The first key point is naturally the storage of antimatter energy.
In space, there is nothing more important than energy. In a sense, it is even more important than the millions of types of materials.
The reason is very 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, the carbon dioxide can also be reused.
Reduced to oxygen and carbon.
Faced with a mass of up to ten trillion tons, a rough estimate shows that the antimatter energy required is at least 600 million tons. Allow for redundancy, and then double it, it will be as high as 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 drinking blood. From that moment until now, all the energy received by the earth from the sun has driven wind, rain, thunder and lightning, driven the growth of all things, driven rivers, and driven ice and snow.
All the energy melted is only enough for this one voyage.
In order to prepare up to 1.4 billion tons of antimatter, approximately 11.7 billion tons of hydrogen are required to be completely converted into energy, and a trillion tons of fusion fuel is 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.
Therefore, 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 do not need to consider a series of things such as mobility and weapon systems. But this time the spacecraft that needs to be built is too large.
A spaceship the size of the Voyage has never been built before.
Fortunately, during the process of repairing and maintaining the Yuan Voyage spacecraft, people have accumulated a lot of data, and they are still confident 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 to survive.
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, that is, the problem of large-scale preparation of antimatter energy. Solving this problem has almost solved 99% of the problems in interstellar navigation.
question.
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. We can 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, this task is actually relatively easy. The most important thing is that human civilization now has the experience of an interstellar voyage. It has to know what materials should be carried during the voyage and what proportion of a certain type of materials should be carried.
, most of them know it well.
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 other projects. The most obvious example is that the market economy has once again suffered a devastating blow at this stage. The entertainment industry, and the service industry
, clothing, home textiles, tourism and other industries were almost completely wiped out. All practitioners were guided to participate in these three giant projects, and 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 most 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 provide them with resources at the moment.
The life of every scholar is precious. In order to cultivate them, civilization has spent huge resources and costs. However, wasting their lives on work with little technical content is a huge waste.
Therefore, based on the principle of voluntariness, many scientific researchers chose 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. So, as long as the values of civilization and the bottom line of morality are not involved, he will definitely do it and not
Will care about "the value of life", "the value of life" and other debates that have no right answers.
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 forces of the military have also been allowed to enter hibernation and temporarily freeze their own
Most of the remaining soldiers were devoted to this "war".
Yes, these three projects are a kind of war for human civilization. Certain tasks that require an extremely high degree of organization and the participation of fast mobile forces are just suitable for soldiers to complete.
For the soldiers, this also has a function similar to military exercises, so that they will not forget all the skills they learned through hard training in the past.
Under such circumstances, 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 spray of electromagnetic railguns, are either shuttling 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 landscape of these three planets was 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 affected 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. However, under people's intentional control and observed from outside this galaxy, the galaxy still maintains calm.
At least with the current level of science and 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 were born naturally and came into 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 before people's eyes. A huge amount of materials with a mass calculated in trillions of tons, under the spray of the electromagnetic railgun,
Gradually they gathered among these spaceships.
One after another, the space cities that originally had their own style, carried people's different life histories, and retained many people's memories were abandoned, and eventually lost all temperature, becoming as cold as interstellar meteorites. One after another, they originally roared day and night, and people flowed in.
The huge, weaving factory gradually stopped, returning the coldness and deathly silence to this world.
Human civilization is like a passing guest, only staying for a brief moment in the life of this galaxy that lasts at least tens of billions of years. Now, it is time to leave.
