The last human in the universe

Chapter 142 Three Body
With the irresistible exposure of the fact that "Vilagash is the biggest traitor", no matter who it is, one can imagine that many interesting things will definitely happen within the Moyun Litar civilization.

People are looking forward to it.

But everyone also understands that this kind of thing can only be expected.After all, no one can obtain information about the interior of the Moyun Litar civilization again.

Now, it's time to come to an end about the Moyun Litar civilization and put it down 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 support of more than a dozen dwarf planets and the continuous abundance of materials from the Jupiter system, and the technological support from the Moyun Litar civilization, the repair process of the Yuanhang spacecraft went very smoothly.And when the spacecraft repair entered the second half, another extremely important matter was placed on Zhao Changxing's desk.

It's time to prepare the materials needed for this interstellar voyage that is destined to take a long time and is destined to be full of dangers.

This is the unprecedented first interstellar voyage in the entire history of human civilization.

Even traveling alone requires enough luggage, not to mention the interstellar migration of millions of people in the entire civilization.

This matter must rise to the level of the entire civilization, and Zhao Changxing will be in charge of it himself, and all major science academies and institutions will unite to complete the drafting of the final list.The subsequent actual material collection process will take up to hundreds of years.

The destination of this voyage has been determined at this moment.

In the previous discussion process, combined with the natural conditions such as the galaxy composition of the target galaxy, the environment of the main star, and the degree of activity, and considering the possibility of future pursuits from the Moyun Litar civilization, people finally ruled out more than a dozen candidate galaxies, and finally set the target galaxy as EZ Aquarius.

The EZ Aquarius galaxy is a triple star system, that is, three stars orbiting each other.

It is a true three-body galaxy.Because the mass gap of the three stars that make it up is not too big, 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 two-star system, such a galaxy is not strictly speaking a three-body galaxy.Because the three stars that make it up have too much difference in mass, and the distances between them are also too far apart.

The mass of Nanmen 1.1 A star is as high as 0.9 times that of the sun, and the mass of Nanmen 16.7 B star is also 53 times that of the sun.The distance between the two is only [-]-[-] billion kilometers, which is very close.

The Nanmen 0.12 C star, also known as Proxima Centauri, has a mass of only [-] times that of the sun, and is as high as two trillion kilometers away from the two main stars.

Such a small mass and such a large distance make it impossible for the three to form a strict three-body system.Proxima Centauri looks more like a companion star to its two primary stars.

EZ Aquarius is not the same.The three main stars that make up it are all close to each other, and their masses are not much different.This makes their orbits truly unpredictable and chaotic.

At present, scientists of human civilization have proven that there are two planets in the EZ Aquarius galaxy - one is a rocky planet with a mass about 2.7 times that of the Earth, and the other is a gaseous planet with a mass about that of Jupiter 1.6 times.

And there are abundant satellite systems in this galaxy, as well as many asteroids, comets, etc., the resources can be regarded as quite rich.

Of course, this is just an absolute value.If you want to talk about relative values, that is, compared with other star systems, it is mediocre, and it can even be regarded as a relatively harsh environment.

After all, the Trisolaran system cannot be played by any civilization.In addition, these three stars are all flare stars, that is, stars with periodic radiation bursts, which makes the internal environment of the galaxy even worse.

If there is an alternative, I am afraid that no civilization will choose to target this star system.

But human civilization has chosen this place.

This was done mainly to confuse the Moyun Litar civilization and prevent them from tracking their own side.

Once the destination is determined, the resource abundance of the target star system needs to be taken into consideration.Resources with more reserves at the target can be appropriately reduced.For those with less reserves, it is appropriate to bring more.

This is a vast list of luggage with tens of millions of materials.

Resources, spare parts, consumables, energy, basic necessities of life, 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 the survival of people.

For the Yuanhang spacecraft, there is no doubt that antimatter should be selected for energy.Just a rough calculation - based on the total mass of Yuanhang spacecraft being 2000 billion tons, and the maximum voyage speed being 0.08 times the speed of light, that is about 2.4 kilometers per second, the mass of antimatter required to complete this voyage is, At least it must reach the order of tens of millions of tons.

The energy released by the reaction of just one gram of antimatter and positive matter is equivalent to the simultaneous explosion energy of tens of thousands of TNT explosives.However, what is the energy released by the explosion of 1000 million tons of antimatter?
The calculation result is that about 1.8*10^27J of energy can be released.And this energy is equivalent to the sum of the solar radiation energy received by the earth in about 330 years.

Now, these winds, rains, thunders and lightnings that were originally enough to support the entire earth for hundreds of years, the energy that supports the flourishing of all things on the earth, the thriving life, the surging waves, and 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 can only produce antimatter particle by particle in the high-speed particle collider.

To obtain tens of millions of tons of antimatter in this way, it 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, there is the technology and equipment of the Moyun Litar civilization.

After the Yuanvoyage spacecraft was driven by Viragash to reach the solar system, it was originally planned to obtain enough antimatter in the solar system, and then use it to return to the Laland 21185 galaxy.Of course they have all the equipment.

The operating principle of this kind of equipment is probably directly produced through the fusion of hydrogen.On average, for every kilogram of hydrogen element converted into energy, about 120 grams of antihydrogen will be produced.Then, through the magnetic field control equipment, it is restrained and stored in an extremely high-purity vacuum environment.

It should be pointed out that due to the influence of vacuum fluctuations, that is, virtual particle pairs will continuously and spontaneously emerge in the vacuum, even if it is stored in a special container with an extremely high vacuum environment that is not in contact with any object, the antimatter It will also decrease slowly and spontaneously.

The principle is probably similar to the Hawking radiation of black holes.

For this reason, people had to increase the original 1000 million tons of antimatter reserves by another ten percent to 1100 million tons.Adding about 20% of redundant reserves, the total amount of antimatter that needs to be produced is as high as 1320 million tons.

In conversion, a total of about 1.1 trillion tons of hydrogen is required to be completely converted into energy to be produced.According to hydrogen fusion, the conversion efficiency is about 0.7%, plus some losses, the total fusion raw materials needed are as high as 200 trillion tons.

Such a huge project undoubtedly requires the input of the entire civilization, and it will take a long time to complete the preparations.

So, on Sedna, on other dwarf planets, and in space, fusion factories sprang up one after another, trying their best to produce the antimatter energy needed.In order to support the operation of these factories, the delivery of materials from other planets to here has also reached an unprecedented peak.

The storage of antimatter energy is only a small part of the huge material storage plan.In other aspects, the major grain workshops are rapidly producing rice, flour, grain, oil, salt, sugar cotton and other foods that are easier to store at a crazy speed, and they are well stored in a special storage environment.

Major chemical factories also need to run overnight to produce and store a large number of chemical raw materials.For the rest, all kinds of industrial products, ranging from a spoon to a mechanical car, are produced as far in advance as possible.

The production of these things also consumes energy.It can be foreseen that it is basically impossible for the Yuanhang spacecraft to obtain external resource supplements during its voyage.In this way, it is best to produce them first when they can still be replenished at this moment.

Time passed slowly, and when the resource reserve plan was carried out for a full 100 years, the repair work of the Yuanhang spacecraft finally achieved phased results.

On this day, under the personal attention of Zhao Changxing, the Yuanhang spacecraft conducted its first propulsion test and achieved the expected results.

During the long-term development, hibernation technology is gradually becoming mature.

Time is still passing, and when almost 80 years have passed, the main tasks of the material reserve plan and the spacecraft repair plan have been completed at the same time.All that's left is just a few finishing touches.

At this moment, looking at the Yuanhang spacecraft, which is barely repaired although it is full of patches, and looking at the giant factories everywhere on the surface, underground and sky of Sedna, Zhao Changxing knows that the real time to set sail , is not far away.

A message was sent from Sedna to the Jupiter system at this time.

"My fellow citizens, get ready to set sail."
