With the irresistible exposure of the fact that "Vilagash is the biggest traitor", no matter who you are, you can imagine that many interesting things will definitely happen within the Moyunlitar civilization.
People are looking forward to this very much.
But everyone also understands that this kind of thing can only be expected. After all, no one can obtain the internal information about the Moyun Litar civilization again.
Now, the matters related to the Moyun Litar civilization should come to an end and be put aside for the time being. Next, going all out to repair the Yuanhang spacecraft is the most important thing for the entire human civilization at this stage.
With the continuous abundant material support from more than a dozen dwarf planets and the Jupiter system, and the technological support from the Moyun Litar civilization, the repair process of the Yuanhang spacecraft was very smooth. As the spacecraft repair entered the second half, another extremely important thing was placed on Zhao Changxing's desk.
It was time to prepare the supplies needed for the interstellar voyage that was destined to be long-lasting and dangerous.
This is the first interstellar voyage unprecedented in the entire history of human civilization.
Even a person needs to prepare enough luggage when traveling alone, let alone the interstellar migration of an entire civilization and millions of people.
This matter must be raised to the level of the entire civilization, with Zhao Changxing personally taking charge, and all major academies of science and major institutions uniting to formulate the final list. The subsequent actual material collection process will take up to hundreds of years.
The destination of this voyage has now been determined.
During the early discussions, combined with the natural conditions such as the target galaxy’s galaxy composition, main star environment, activity level, and considering the possible pursuit from the Moyun Litar civilization in the future, people finally ruled out more than a dozen candidate galaxies, and finally the target galaxy was ez Aquarius.
The EZ Aquarius galaxy is a triple star system, that is, three stars orbiting each other together.
It is a true three-body galaxy. Because the mass difference between the three stars that make up it is not large, about 0.1/0.11/0.11 times the mass of the sun respectively.
Similar to the star system closest to the sun, the Nanmen 2-3 star system, such a galaxy is not strictly a three-body galaxy. Because the mass gap between the three stars that make up it is too large, and the distance between them is also too far apart.
The mass of the star Nanmena A is as high as 1.1 times that of the sun, and the mass of the star Nanmen2 b is also 0.9 times that of the sun. The distance between the two is only 1.67-5.3 billion kilometers, which is very close.
The star Centauri c, also known as Proxima Centauri, has a mass of only 0.12 times that of the sun and is about two trillion kilometers away from the two main stars.
With such a small mass and such a large distance, the three cannot form a three-body system in the strict sense. Proxima Centauri looks more like a companion star to the two main stars.
But Aquarius ez is different. The three main stars that make up it are all close to each other and have similar masses. This makes their orbits truly unpredictable and chaotic.
At present, scientists of human civilization have discovered that there are two planets in the EZ Aquarius galaxy - one is a rocky planet with a mass of about 2.7 times that of the Earth, and the other is a gaseous planet with a mass of about Jupiter. 1.6 times.
Moreover, there are abundant satellite systems in this galaxy, as well as many asteroids, comets, etc., and the resources can be considered quite abundant.
Of course, this is just an absolute value. If we talk about the relative value, that is, compared with other star systems, it is mediocre, and it can even be considered a relatively harsh environment.
After all, not just any civilization can play with the Trisolaran Galaxy. In addition, these three stars are all flaring stars, which are stars that periodically burst out with radiation, which makes the internal environment of the galaxy even worse.
If there were alternatives, I am afraid that no civilization would choose this star system as its target.
But human civilization chose this place.
This is mainly done to confuse the Moyun Litar civilization and prevent them from tracking us.
Once the destination is determined, the resource abundance of the target star system needs to be taken into consideration. For resources with large reserves at the target, you can bring less resources appropriately. If the reserves are small, it is appropriate to carry more.
This is a vast luggage list with tens of millions of items.
Resources, spare parts, consumables, energy, food, clothing, housing, transportation, food, etc.
Among them, the most important is undoubtedly energy.
Energy is the most important resource to propel the spacecraft forward, and it is also the most important category to maintain the internal operation of the spacecraft and maintain people's survival.
For the Yuan Voyage spacecraft, there is no doubt that antimatter should be chosen as the energy source. Just a rough calculation - assuming that the total mass of the Yuanhang spacecraft is 200 billion tons and the maximum sailing speed is 0.08 times the speed of light, which is about 24,000 kilometers per second, the amount of antimatter mass required to complete this voyage is calculated , at least on the order of tens of millions of tons.
When just one gram of antimatter reacts with positive matter, the energy released is equivalent to the energy of tens of thousands of tons of TNT explosives exploding simultaneously. And, how much energy is released by the explosion of 10 million tons of antimatter?
The calculation result is that approximately 1.8*10^27j energy can be released. This energy is equivalent to the total solar radiation energy received by the earth in about 330 years.
Now, these wind, rain, thunder and lightning, which were originally enough to support the entire earth for hundreds of years, support the flourishing of all things on the earth, support the prosperity of life, support the endless surge of waves, and support the flow of countless rivers and streams day and night, will all It is used to promote the acceleration and deceleration of the Yuanhang spacecraft, and to maintain the operation of various internal equipment.
Before obtaining the equipment and related technical support of the Moyun Litar civilization, human civilization could only produce antimatter one particle at a time in a high-speed particle collider.
To produce tens of millions of tons of antimatter in this way is undoubtedly a dream. Even if the energy of the entire sun is consumed, it is impossible to produce so much.
The efficiency of this preparation is really too low.
Fortunately, the technology and equipment of the Moyun Litar civilization are there.
After the Voyage spacecraft arrived in the solar system driven by Villagash, it was originally planned to obtain enough antimatter in the solar system and then use it to return to the Lalande 21185 system. Of course they have all the equipment.
The operating principle of this equipment is probably to produce it directly through the fusion of hydrogen elements. On average, for every kilogram of hydrogen element converted into energy, about 120 grams of antihydrogen will be produced. It is then bound and stored in an extremely high-purity vacuum environment through magnetic field control equipment.
It should be pointed out that due to the influence of vacuum fluctuations, that is, pairs of virtual particles will constantly and spontaneously emerge in the vacuum, even if the antimatter is stored in a special container in an extremely high vacuum environment that does not come into contact with any object, antimatter It also decreases slowly and spontaneously.
The principle is probably similar to the Hawking radiation of black holes.
For this reason, people had to increase the original antimatter reserves of 10 million tons by another 10% to 11 million tons. Coupled with about 20% redundant reserves, the total amount of antimatter that needs to be produced reaches 13.2 million tons.
Converted, it would take a total of about 1.1 trillion tons of hydrogen to be completely converted into energy to produce it. According to hydrogen fusion, the conversion efficiency is about 0.7%, plus some losses, and the total required fusion raw materials are as high as about 200 trillion tons.
Such a huge project will undoubtedly require the entire civilization to invest, and it will take a long time to prepare completely.
As a result, on Sedna, on other dwarf planets, and in space, fusion factories were built one after another, trying their best to produce the required antimatter energy. In order to support the operation of these factories, the transportation of materials from other planets to here has also reached an unprecedented peak.
The reserve of antimatter energy is only a small part of the huge material reserve plan. In other aspects, major grain workshops are rapidly producing rice, flour, grains, oils, salt, sugar, cotton and other foods that are easier to store at a crazy speed, and are stored intact in a special storage environment.
Major chemical factories also need to operate throughout the night to produce and store numerous chemical raw materials. The rest, various industrial products, as small as a spoon or as large as a mechanical vehicle, are produced as early as possible.
The production of these things also requires energy. It is foreseeable that during the voyage of the Yuanhang spacecraft, it is basically impossible to obtain external resource supplements. In this way, it is best to produce them first while resources can still be replenished.
Time passed slowly, and when the resource reserve plan had been carried out for a full hundred years, the repair work of the Yuanhang spacecraft finally achieved initial results.
On this day, under the personal attention of Zhao Changxing, the Yuanhang spacecraft conducted its first propulsion test and achieved the expected results.
Hibernation technology has gradually matured during its long-term development.
Time is still passing, and almost 80 years have passed. The material reserve plan and the spacecraft repair plan have completed the main tasks at the same time. All that's left are some finishing projects.
At this moment, looking at the Yuan Voyage spacecraft that, although it was fully patched, could barely be considered repaired, and looking at the giant factories everywhere on the surface, underground and in the sky of Sedna, Zhao Changxing knew that the real moment to set sail was , not far away.
A message was sent from Sedna to the Jupiter system at this time.
"Compatriots, prepare to set sail."
