The last human in the universe

Chapter 143
Among the huge amount of materials needed for the journey of the Yuanvoy spacecraft from the solar system to the EZ galaxy of Aquarius, a considerable part of it was produced on-site in the Jupiter system.

After all, it takes a long time to transport various resources from the Jupiter system to Sedna, and requires a lot of extra manpower and material resources.

Especially the huge amount of hydrogen needed to produce antimatter - on Sedna Star, electrolysis of water is required to obtain hydrogen, and Sedna Star is actually not rich in water resources.

But it's different in the Jupiter system.Several large moons of Jupiter are covered with water ice, and even a whole moon is covered with water ice.

But getting hydrogen at Jupiter doesn't require electrolysis of water.Jupiter itself is a huge, inexhaustible source of hydrogen.

At this moment, both the restoration task and the resource reserve task have come to an end.Now, besides continuing to put in the finishing touches, one needs to think about another issue.

In the solar system, how to deal with so many infrastructures and factories left behind.

Even most of the spaceships need to be disposed of.Because these spaceships, such as those combat spaceships, civilian spaceships, and cargo spaceships made by humans, obviously cannot be brought to another star system.Nor are they of such great value in themselves.

Even the three space carriers that have made great achievements and can be called the soul of the human escort fleet, as well as hundreds of space cities that have provided living and working places for millions of humans, and even the fire that has special significance for humans People don't intend to take away the spacecraft, but will directly dispose of it.

However, wouldn't it be too wasteful to just blow it up like this?
Zhao Changxing looked at the evaluation data in front of him with a calm expression.

"According to preliminary statistics, the total number of spaceships and aircraft that need to be disposed of is as high as 2.5, with a total tonnage of 221.6 billion tons. The total number of factories of various types that need to be disposed of is as high as 1.6, and the total amount of materials weighs more than 100 billion tons. In addition In addition, there are too many roads and infrastructure, etc., to be counted.”

Zhao Changxing once again called the rest of the civilization leaders and some scientists into the meeting room.

"It's too wasteful to just dispose of it like this. Can you think of a way to recycle the waste?...I mean, can these things create some obstacles for the Moyun Litar civilization that will reach the sun in the future?"

What Zhao Changxing said made people ponder.

Of course people are happy to create obstacles for the enemy.But the crux of the problem is, how to make it?
Just relying on these scraps of iron that are destined to be discarded?

"I've already had someone calculate it." Zhao Changxing said, "Or, we can try and use these things to find a way to bring the black hole closer to the sun."

"This, I'm afraid it won't work." A scientist objected: "At this moment, the black hole has 15 times the mass of the earth. We can't push it at all."

During these nearly thousand years, the black hole has always surrounded the sun, absorbing the gas from the sun and turning it into its own mass.

It would take an extremely long time to swallow the sun whole.According to model estimates, this time may be as high as about 7 years.During this process, the mass of the black hole gradually increases, and the mass of the sun gradually decreases. The rate at which it absorbs solar matter will also increase with the increase of its own mass.

But if we can find a way to change the orbit of the black hole to make it closer to the sun, then obviously, the speed at which it absorbs solar matter will increase again.And this has a series of consequences.

In addition to the gravitational chaos caused by material transfer and the orbital disorder of the major planets, the most direct consequence is that the radiation intensity from the "sun-black hole" binary star system will be greatly increased.

Because the rate of absorbing solar matter increases, correspondingly more mass will be converted into energy and emitted in the form of radiation.

At that time, I am afraid that distant planets as far away as Sedna Star will be affected by radiation.

This will make the environment of the entire solar system worse.

Of course, this cannot cause too much trouble for a powerful third-level civilization like the Moyun Litar civilization.Model simulations show that this can at most only result in an efficiency reduction of about 2%-2.6% for the resource gathering operations of the Mohrite civilization, but…

The improvement of the radiation efficiency of the black hole accretion disk will make it more difficult to mine "superionic metals", and even make it completely unfeasible.

This way, it will be very interesting.

The Moyun Litar civilization, which was severely torn apart by the society, came to a galaxy that was expected to be very rewarding. As a result, super-ionic metals could not be mined, and the environment of the galaxy was still so harsh that the most basic resource collection tasks of our own were restricted. Obstacles, then, with this opportunity, will a civil war be born?

Even if there is no civil war, will the political struggle between the leftists and the vagabonds rise to the point of bloody conflict?Will social efficiency be reduced? Will "partisanship" be serious enough to slow down the entire civilization?

These are all things to look forward to.

If, by relying on some broken metal that is destined to be abandoned, this goal can be achieved, of course people are willing to do it.So now there is only one problem left.

How to do it?

Zhao Changxing raised his head, his expression still calm.

"Of course we can't do it by relying on our strength alone. But with the help of the environment and strength, it is possible to do this.

Fill all the spaceships to be abandoned with supplies that we can't take away.Then let the spacecraft hit the asteroid 856g3 at the fastest speed and with the highest kinetic energy.To change its orbit, let it hit Vesta, to change the orbit of Vesta, and make Vesta directly hit the black hole. "

This series of impacts will produce a domino-like effect.

The initial dominoes may be small, but small dominoes can knock down dominoes that are slightly larger in mass than themselves.This continues, because the fall of a very small domino at the beginning can eventually lead to the fall of a very large domino.

Human power is limited.But now that the gravity of the solar system is chaotic, it is possible to use the power of nature itself to accomplish things that could not be accomplished by itself.

The most important thing is that this mission does not require humans to pay too much, and does not require people to build more engines or propellers.Just use those spaceships that were originally intended to be discarded to complete it.

Zhao Changxing's plan made people look serious unconsciously.

"Yes. Let's make a detailed plan right now."

After that, the huge demolition task officially began.

The first to be solved are the man-made structures located underground and on the surface of the major dwarf planets.

People are too lazy to expend more power to transport them to space.Simply blow up the matter directly.

This is a very simple matter.What people need to do is just to throw in the encapsulated standard antimatter block of tens of hundreds of milligrams, up to a maximum of one gram—or antimatter bomb.

In the face of the super energy erupted by the annihilation of positive and negative matter, no matter whether it is steel or plastic, no matter whether it is rock or soil, all will be turned into dust.

Seeing these factories, cities, roads, warehouses, etc. that took hundreds of thousands of years to accumulate slowly, were blown up one by one, people looked heavy and didn't know what it was like.

Several space elevators, which were built with untold hardships and made great contributions to the advancement of human civilization into space, were also demolished.

In this process, the large relocation work has also begun.

When deciding on the list of hibernators and waking ones, Zhao Changxing followed the principle of voluntariness more. It is up to people to choose whether to spend the rest of their lives during the voyage, or to temporarily freeze their lives and wait until they arrive at their new homeland before starting. .

EZ Aquarius is a whopping 11.3 light-years away from our solar system.With the performance of the Yuanhang spacecraft and its maximum speed of 0.08 times the speed of light, including the acceleration and deceleration time, it will take about 200 years in total.

Its acceleration is only 0.02 meters per square second.It needs to continue to accelerate for nearly 40 years to accelerate to the top speed.After that, it will enter inertial navigation, and at the end of the voyage, it will decelerate for another 40 years before it will actually reach its destination.

This length of time has exceeded the average life expectancy of people today.

The final statistical result is that out of a total population of about 700 million, about 680 million people have chosen to hibernate.There are less than 20 people who choose to be awake.

Sufficient manpower is also needed to maintain the normal operation of the Yuanhang spacecraft.There needs to be enough engineers and workers to monitor the operation of each module of the spacecraft, and manpower is needed to troubleshoot and so on.Such a small number of people is totally not enough.

In particular, the 20 people who chose to be sober are not exactly the talents needed to maintain the operation of the spacecraft.Most of them are just normal people.

As a last resort, Zhao Changxing had to promulgate a policy of hibernation in turn, forcing some professionals to stay awake and work for a certain period of time before they can enter the hibernation state.

In addition, ordinary people also need to wake up regularly to avoid the damage caused by long-term hibernation.For this group of people, Zhao Changxing also reserved enough space for activities in the Yuanhang spacecraft.

Under the back-and-forth flight of the ferry ship, people with a small amount of luggage—there is a strict review standard for the luggage allowance, and Zhao Changxing does not allow any meaningless increase in the quality of the spaceship—carrying their families with them, they walked away step by step. This has allowed itself to live almost all its life in the homeland.

The noisy space cities in the past quickly became deserted.

It is deserted in the true sense.

Because the life support system has been shut down, there will be no heating equipment to maintain the temperature.

As the internal temperature dropped, the gaseous air gradually solidified, eventually turning into blue ice crystals and falling to the ground.

　. . . .In the future, let’s change it every day, not three times, I can’t fight anymore, and I feel that it’s meaningless to fight so hard. . .

　　Yesterday, the ticket request form was deleted, and there is no need to ask for tickets, so let's do whatever you want. . .
