Deep Space Fleet

Biquge www.xbiquge.bz, the fastest update of Wandering Fleet in Deep Space!

Ding Peng's eyes drifted to the distant sky. There are no stars here, just a bleak void, where people will live and develop for a long time.

At this moment, the male voice on the TV also became high-pitched: "...when the flame of the planetary engine shines in this starry sky, we will finally embark on the road of a fourth-level civilization!"

Many people cheered loudly and applauded. Even the other geniuses selected from the virtual world, no matter whether they are used to this world or not, are raising their glasses to celebrate, wanting to contribute their own strength to it.

But few people know that the beginning of something is always good. Especially for such a big project, if there is no bright future, how many people will have the courage to do it?

The government has not said how long the project will ultimately take...

However, when nearly 20 million people have consumed a huge amount of points, spent a hundred years on the road, enjoying themselves to reach the finish line, and are about to start a new journey, they don't know that there will be nearly three thousand years of difficult times in the future. waiting for them...

The loud cheers now may be the last cheers in the next three thousand years.

Until death, they have to repeat the same work.

The 15,000 planetary engines that humans are responsible for are equivalent to 15,000 mountains pressing on the entire civilization. Many people will have to give up their current occupations and devote themselves to the vast ocean of large-scale construction projects.

They have to fight with excavators and ground drilling machines all their lives, and use these tools to level the craters one after another.

From cheering and laughing at the beginning, then gradually becoming numb, and finally bringing deep despair into the grave...

The cultivation of talents for the next few generations will also be heavily tilted in this direction.

A large proportion of engineers will appear, and many entertainment-related occupations will be banned. Even the work of many scientists had to be abandoned because the entire civilization was no longer productive and provided them with the resources to experiment.

No passion can last for three thousand years. The first generation of people died silently, fighting for their beliefs and ideals all their lives, but the second generation of people had to accept the status quo that has become a fact, and continue to struggle because of social inertia... …

The third generation is still doing the same thing, and it's impossible for them to feel the ambition that people had when they first came here.

This social inertia is slowly exhausted, and then the fourth generation, fifth generation, sixth generation...

Even if a generation is born in fifty years, a relay of 40-60 generations is needed to survive these thousands of years.

Without any enthusiasm, it can sustain 40 generations of people to repeat the same work. They were born and began to see the world with their eyes open. There are no stars, no light, and huge planetary engines are ejecting plasma sparks. Until they die, they are still building planets engine.

After a beautiful rainbow, watching it for a lifetime has become an extremely boring thing.

But they just have to spend a lifetime of energy to do this, and they must do it seriously. The current robot system has no way to independently manufacture such a giant as a planetary engine, and a large number of personnel must be required to work and maintain the entire system.

In particular, there is no one to force them without any pressure to survive, and there are no alien enemies in this place.

The only spiritual support is that there is a certain probability of becoming a fourth-level civilization.

However, the benefits of becoming a fourth-level civilization belong to all mankind, to future generations, and not to oneself.

"People have to rely on spontaneity to maintain their jobs, and 'spontaneity', for us, is nothing more than a distant dream."

"So, Mr. Captain, don't think about the progress of the Toss civilization, and don't care whether they can persist. The future expectations on our side are unreliable. Although everyone's current enthusiasm is very high, it will take a long time. Time can always wipe out all the passion."

"They're going to get lazy."

"The whole construction period is too long, so long that it makes our short-lived species hopeless."

"Will you die if you don't work? You won't die! Work pressure is too low, and we can't force workers to work by squeezing their labor power..."

On this day, the planetary fortress has arrived at the intended location.

Just out of the curvature bubble, the two sides immediately dispatched a large number of scientific research experts to conduct on-the-spot investigations, which are expected to last for a month.

Various large-scale nuclear fusion flares with an equivalent of tens of millions of tons of TNT shine in the starry sky. These flares are like bright little suns, temporarily illuminating this bleak universe.

After this, it will be a matter of choosing whether to stay or return.

If they want to stay here, the two civilizations will unload a large number of construction machinery in the planetary fortress and start formal engineering. Of course, if nothing special, the general opinion is to stay here.

Zhang Yuan and a small group of people were worried, and turned their eyes to a more distant time.

During their discussions in the past few days, they felt more and more that people seemed to overestimate their own determination and the ambitions of human beings themselves.

The whole atmosphere is too optimistic, really too optimistic. The plan formulated by the new human government has great flaws, especially in terms of personnel mobilization, which has a certain degree of flaws...

"At that time, if you are lazy and I am lazy, the entire construction period will be delayed. If you are lazy again, and I am lazy again, the entire civilization will immediately lose its original spirit. Although everyone knows that this Engineering has greatly benefited humans, but... humans are still self-interested creatures."

Optimism is a good thing. But being too optimistic can easily overestimate yourself.

Does the empire on which the sun never sets want to weaken? The empire on which the sun never sets does not want to be weak, the high officials and nobles of the empire on which the sun never sets do not want to be weak, and the common people do not want to be weak.

Do Americans want to be weak? Americans don't want to, no one wants to be weak.

"However, the decline of a country or even a civilization is not only caused by external challengers, but also by a powerful competitor, and more of an internal reason..."

"...It is because their society, their systems, policies, and the mental state of the people have not kept up with the times, so that competitors have an opportunity to take advantage of."

"The same is true for our civilization. A civilization is dynamic and will not remain static. Our policies should change with the times in order to keep the entire civilization moving forward. But now there is an invariant, that is, we must always adhere to this This is a big project, which will cause great troubles for future policies..."

Facing the eloquent and joint proposal of hundreds of senior officials, these high-level civilized officials were all in a state of bewilderment, and a special meeting was held specifically for this purpose.

In the end, Mr. Captain sighed and said: "Then, Mr. Zhang Yuan, what better suggestion do you have? It is impossible for us to force workers to do thousands of years of work, otherwise this government will become a dictatorship. Sooner or later it will be overthrown."

Zhang Yuan smiled and said: "Of course there are suggestions. The best way is to shorten the construction period. To shorten the original two battle stars to one, you can refer to Alternative 17."

Alternative 17 is a plan designed by Zhang Yuan's good friend, physicist Professor John.

The general plan is to build two planetary fortresses, one of which is placed at a distance of 120-200 astronomical units to observe the collision of neutron stars, and the other to interfere with the mutual rotation between the two neutron stars for Reduced collision time.

Otherwise, human beings will have to wait for more than 100,000 years to wait for the neutron star collision, which is too long.

More than 100,000 years is absolutely unrealistic for human beings. It is impossible for the Tuos people, who have a longer lifespan, to wait for such a long time.

"So, this planetary fortress for shortening neutron star collisions is essential."

"But another battle star placed at 120 AU, can it be saved instead of being built?"

Professor John's No. 17 backup plan, after careful calculation, believes that it is sufficient to build only one planetary fortress under certain circumstances.

As far as the current astronomical observation is concerned, there is no suitable planet at 120 AU. The equipment for observing neutron star collisions is best built on planets, so that there is a greater chance of observing the required data.

Is it possible for people to push a planet to 120 AU without building a planetary engine?

Of course there are!

The answer is...Using the huge gravitational force that must build a planetary fortress to pull another planet over!

Since human beings want to build at least one planetary fortress, let it play more roles. The first is to use its own gravity to entice the movement of another planet and bring the other planet to the goal of 120 AU After the orbit, it is the second goal, to do a three-body motion with the neutron star, or in other ways, to shorten the mutual revolution between the two neutron stars.

The gravitational force between planets is like two magnets attracting each other, which can form a power source for each other.

Take the former Earth-Moon binary star system as an example. It is precisely because of the existence of gravity that the two parties form a system.

The earth-moon system is not a simple moon revolving around the earth, but the earth and the moon revolve around the center of mass of the earth-moon system, but the mass of the earth in the earth-moon system is large and the moon is small, and their common center of mass is about 4800 kilometers away from the center of the earth , being wrapped by the earth, it looks like a simple moon revolving around the earth.

Once a large number of planetary engines are installed on the earth to make the earth deviate from its own orbit, the moon will come along with it, and it will be impossible to get rid of it in a short while.

In the same way, installing an engine on the moon to make the moon move will also interfere with the movement of the earth.

If you really want to "wander the earth", it is a more reliable plan to use the moon as a constant source of gravity to lure the earth to run. After all, the thin crust of the earth cannot support those powerful planetary engines.

The No. 17 plan proposed by Zhang Yuan and others is this. Only one battle star is built, and it is activated to hook another planet, forcibly attracting it to change its orbit.

In this way, humans do not need to build a second planetary fortress, but only need to install various observation devices on this big ice ball.

"It would definitely be good news for us if the project period could be cut in half."

These officials all showed contemplative expressions. The plan sounds good, but the technical difficulty is undoubtedly an order of magnitude greater.

The movement of a planet is not driving. It does not mean that you can turn left if you want to turn left, and turn right if you want to turn right. Under the action of its huge inertia, if you want to turn from left to right, you may need A hundred years!

If you want to move other planets, you need to use its own inertia and precise calculations. Maybe you accidentally bump into it. This is not alarmist!

A scientist raised his brows and said slowly, "Mr. Zhang, in Plan No. 17, the big ice ball selected is quite large, with a diameter of 2,000 kilometers. Although its density is very low, its mass It's not high...but if you want this big ice ball to run with our planetary fortress, the distance between the two sides must be close enough for the gravitational force to be strong enough for the plan to succeed."

"After more than 500 years, the distance between the two planets will reach the closest point, and there is a chance of gravitational hook. Therefore, it is best for our planetary fortress to move its orbit to the same height within 500 years... ..."

"But if the positions of the two planets are too close...it's too dangerous! The two planets no longer revolve around, but one after the other."

"Our battle star must run fast enough, and the planetary engine must have sufficient horsepower, otherwise the distance between the two sides will become closer and closer under the action of gravity, and they may collide, and it will all be over by then!"

Zhang Yuan said with a smile: "Yes, it is because of this that all human beings are motivated to work hard! If they don't work harder, the two planets will directly collide!"

"It's called work oppression, there is no oppression, such a large project, I don't know how long it will take foreign workers, who can guarantee that it can be completed on time and in quantity for thousands of years?"

Everyone was stunned for a moment.

Zhang Yuan continued: "However, this kind of oppression is far from enough. We still need to expand a part of the population, especially in the early stages of the project. The population must reach more than 100 million."

"One hundred million." Mr. Captain frowned and pondered. The previous plan also wanted to expand the population, but it didn't need that much.

Another professor who supported this plan took up the conversation and replied: "The construction period of the No. 17 plan is very tight, far more tense than other plans. If the population does not explode, our industrial production capacity will not be able to meet the standard."

"On the other hand, after a large population expansion, our current spaceship can't hold so many people...or, after holding so many people, it will not be so comfortable. Many people have to live underground. At this time, we can witness With the big puck following behind, the pressure will be even greater.”

"But……"

A member of a government think tank asked: "With such a large population, it will be very difficult to escape... We don't have enough amoeba points, and we don't have enough rented spaceships. In the end, we can only carry 40 million people."

Zhang Yuan explained: "Your question is very good, but don't forget that people will grow old and die. In 1400 years, as long as the planning is good, the final population can be reduced to less than 40 million."

The congressman immediately retorted: "But that will lead to serious aging and various problems. In an aging society, the labor force will be very scarce at that time. Maybe even the elderly will have to participate in the workplace and delay retirement Age! This will cause a lot of social problems!"

There was silence in the air for a while, or it would take more than 3,000 years to work slowly, the future is unpredictable, maybe it will take 4,000 years, 5,000 years, or even give up halfway. Even if the historiography of the new civilization is strong, it is impossible to predict the time of three thousand years.

Either the project volume will be cut in half, but the aging crisis may be endured for a long time, and the people will be persecuted and complain.

Zhang Yuan shook his head and sighed softly, "No way, everything can't be perfect. With a population of 100 million, it takes 400 years for us to work harder and increase the working hours, and we have to complete about 40%-50% of the project The amount can only be handed over to future generations."

"How can a fourth-level civilization be so simple, it always has to suffer."

"After this whole set of combined punches, the project period is about 1400 years. So we can make an agreement with the Huantai civilization that after 1400 years, we will rent some transport spaceships to transport our population to a place one light-year away. Counting the hundred years that have passed, it will be a total of fifteen hundred years."

"If a human fleet comes to the trading market after this, you can also send them news about curvature technology, or simply let them sell the news in the trading market. Hey, if our civilization does not complete the plan, it will stop progress, then let the rest of the human branches progress..."

This feeling is very bitter, everyone knows what Zhang Yuan is talking about...

It actually makes sense.

But how should people choose?

Do you choose a plan that can be completed in 1400 years, or choose a plan that lasts for 3,000 or 4,000 years?

This is the problem of long-term pain and short-term pain.

For 1400 years, there must be risks and hardships. Even a population of 100 million will have to suffer a lot in the face of huge engineering volumes. For example, the working hours will be extended to 10 hours a day.

All kinds of less important occupations will be banned, people will no longer be able to play robot wars games leisurely, and the government will not be able to allocate resources to do this.

And the plan of three or four thousand years... is too long to plan. It is difficult to predict whether there will be conflicts with the Toss civilization during the period, and whether there will be greater variables.

Whether it can be done is another question.

In fact, Zhang Yuan does not believe in his heart that even if human beings have completed this project like a foreign worker, can they go further.
