Chapter 537

Ding Peng's eyes float to the distant sky. There are no stars here, just a dark void. People will live and develop here for a long time.

At this moment, the male voice in the TV set is also loud When the flame of the planetary engine shines in this starry sky, we will finally embark on the road of four level civilization

Many people cheered and clapped for it. Even other geniuses selected from the virtual world, whether they are used to the world or not, are raising their glasses to celebrate, hoping to give them a share of their strength.

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

The government did not say how long the project would eventually take

However, when nearly 20 million people spend a huge amount of points, spend a hundred years on the road, enjoy reaching the destination, and are about to start a new journey, they don't know that there are nearly three thousand years of hard time waiting for them in the future

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

Until they die, they have to repeat the same work.

Human beings are responsible for 15000 planetary engines, which is equivalent to 15000 mountains. Many people will have to give up their current jobs and invest in the vast ocean of large-scale construction projects.

All their lives, they have to fight with excavators and drills, and use these tools to flatten craters.

From the beginning of cheering and laughing, and then gradually numb, and finally bring a thick despair into the tomb

The talent training of the following generations will also incline to this aspect.

A large proportion of engineers will appear, and many entertainment related professions will be banned. Even many scientists have to give up their work because the whole civilization is no longer productive and provides them with experimental resources.

There is no passion that can last for three thousand years. The first generation died in silence and fought for their beliefs and ideals all their lives. However, the second generation had to accept the fact that it has become a reality because of social inertia and continued to struggle

The third generation is still doing the same thing. They can't feel the ambition when people first came here.

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

Even if a generation is born in 50 years, it will take 40-60 generations to survive these thousands of years.

Without any enthusiasm, they can maintain 40 generations to repeat the same work. They were born and began to open their eyes to see the world. There are no stars and no light. The huge planetary engine is ejecting plasma sparks. Until their death, they are still building planetary engines.

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

But they just have to spend their whole life to do it, and they have to do it seriously. At present, there is no way for the robot system to independently manufacture such a huge thing as a planetary engine. A large number of people must work to maintain the whole system.

In particular, in the absence of any pressure to survive, there is no one to force them, and there is no external enemy in this place.

The only spiritual support 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 ourselves.

"People have to rely on spontaneity to maintain their work, and" spontaneity "is like a dream out of reach for us."

"So, Mr. captain, don't think about the progress of the tosian civilization, whether they can persist or not. Future expectations on our side are unreliable. Although everyone's enthusiasm is very high, but the long time, always can all the passion to wear out

"They will grow lazy."

"The whole construction period is too long. It's so long that our short-lived species is desperate."

"Will you die if you don't work? No death! The work pressure is too small, and we can't force workers to work by squeezing their labor force. "

On this day, the Planetary Fortress has reached its place.

Just out of the bubble, the two sides immediately sent a large number of scientific experts to carry out on-the-spot investigation, which is expected to last for a month.

All kinds of large-scale nuclear fusion flares with tens of millions of tons of TNT equivalent are shining in the starry sky. These flares are like bright little suns, temporarily illuminating the dim universe.

After that, people will choose whether to stay or return.

If they want to stay here, the two civilizations will unload a lot of construction machinery from the Planetary Fortress and start formal engineering. Of course, if there is nothing special, the general opinion is to stay here.

However, a small number of people, such as Zhang Yuan, are worried and focus on the more distant time.During their discussions over the past few days, they increasingly feel that people seem to overestimate their determination and human ambition.

The whole atmosphere is too optimistic. The plan formulated by the new human government has great defects, especially in personnel mobilization

"At that time, if you are lazy and I am lazy, the whole construction period will be delayed. If you are lazy again and I am lazy again, the whole civilization will lose its original spirit immediately. Although we all know that this project is of great benefit to mankind, but Man is still a self serving creature. "

Optimism is a good thing. But if you are too optimistic, you will easily overestimate yourself.

Does the Empire want to weaken? The sun never sets Empire doesn't want to be weak, the officials and nobles don't want to be weak, and the common people don't want to be weak.

Do Americans want to be weak? The Americans don't want to be weak either.

"However, the decline of a country or even a civilization is not only caused by external challengers, but also by internal reasons as a strong competitor."

“…… It's because their society, their systems, policies and people's mental state can't keep up with the times, that competitors can take advantage of them. "

"It's the same with our civilization. A civilization is dynamic and will not remain unchanged. Our policies should change with the times so that the whole civilization can move forward. But now there is an invariable, that is, we must always adhere to this big project, which will cause great trouble to future policies. "

In the face of the suggestions of hundreds of high-level officials, all of these civilized high-level officials were in a state of faint loss, and a special meeting was specially held for this purpose.

Finally, the captain sighed and said, "well, Mr. Zhang Yuan, what better advice do you have? We can't force the recruitment of workers to work for thousands of years, otherwise this government will become a dictatorship and be overthrown sooner or later. "

Zhang Yuan said with a smile: "of course, there are some suggestions. The best way is to shorten the construction period. We can shorten the engineering quantity of the original two war stars to one. You can refer to alternative 17. "

Alternative 17 is a scheme designed by Professor John, a physicist and good friend of Zhang Yuan.

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 is to interfere with the rotation of two neutron stars to shorten the collision time.

Otherwise, mankind will have to wait more than 100000 years to wait for the neutron star collision, which is too long.

More than 100000 years is absolutely unrealistic for human beings. The TOS, who live longer, can't wait so long.

"Therefore, this Planetary Fortress for shortening neutron star collisions is essential."

"But can another battle star placed at 120 astronomical units be saved and not built?"

After careful calculation, Professor John's alternative plan No. 17 thinks that it is enough to build only one Planetary Fortress under certain circumstances.

As far as current astronomical observations are concerned, there are no suitable planets at 120 astronomical units. 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 to push a planet to 120 astronomical units without building a planetary engine?

Of course there are!

The answer is Take advantage of the huge gravity of the planet fortress that must be built to drag another planet!

Since human beings have to build at least one Planetary Fortress, we should let it play more roles. The first is to use its own gravity to hook the motion of another star and bring another star to the target orbit of 120 astronomical units. The second is to do three body motion with the neutron star, or in some other way to shorten the phase between two neutron stars They're going around each other.

The universal gravitation between stars, like two magnets that attract each other, can form a power source between them.

Take the Earth Moon binary system for example. It is because of the existence of gravity that the two sides form a system.

The Earth Moon system is not simply that the moon revolves around the earth, but that the earth and the moon revolve around the center of mass of the Earth Moon system. However, the earth mass of the Earth Moon system is large and the moon is small, and its common center of mass is about 4800 km away from the center of the earth. If it is wrapped by the earth, it looks like the moon revolves around the earth.

Once a large number of planetary engines are installed on the earth to make the earth deviate from its orbit, the moon will come with it, and it is impossible to throw it away for a while and a half.

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 we really want to "roam the earth", it is a reliable plan to let the moon act as a constant source of gravity to move the earth. After all, the earth's thin crust can not support those powerful planetary engines.Zhang Yuan and others suggested that this is the 17th plan. They only build a war star, start it to hook another star, and force it to change its orbit.

In this way, humans don't need to build a second planet fortress, just need to install various observation devices on the big ice ball.

"If we cut the project period by half, it will undoubtedly be good news for us."

These officials have shown a thoughtful look, the plan sounds good, but the technical difficulty is no doubt an order of magnitude.

The movement of a planet is not driving. It does not mean that if you want to turn left, you can turn left. If you want to turn right, you can turn right. Under its huge inertia, it may take 100 years to turn left into right!

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

A scientist raised his eyebrows and said slowly: "Mr. Zhang, in the No. 17 plan, the big ice hockey chosen is quite big, with a diameter of 2000 kilometers, although its density is very low and its quality is not high But if we want this big ice hockey to run with our Planetary Fortress, the distance between the two sides must be close enough, the gravity must be big enough, and the plan can succeed. "

"In more than 500 years, the distance between the two planets will be as close as possible, and there will be a chance of gravitational pull. Therefore, our Planetary Fortress had better move its orbit to the same height within 500 years... "

"But if the two planets are too close It's too dangerous! The two planets no longer revolve around, but in the pattern of one before the other. "

"Our war star has to run fast enough, and the planetary engine has to have enough horsepower, otherwise the distance between the two sides will be closer and closer under the action of gravity, and they may bump into each other, and then it will be all over!"

Zhang Yuan said with a smile: "yes, that's why all human beings work hard! If they don't work hard, the two planets will collide directly! "

"It's called work pressure. There is no pressure. I don't know how long it will take for such a big project. Who can guarantee that it can be completed on time and in quantity for thousands of years?"

Everyone was stunned.

Zhang Yuan continued: "but this kind of oppression is far from enough. We also need to expand a part of the population, especially at the beginning of the project. The population must reach more than 100 million. "

"A hundred million." The captain frowned and thought that the previous plan was to expand the population, but it didn't need so much.

Another professor who supported the plan took over the conversation and replied, "the construction period of No. 17 plan is very tight, far more than other plans. Without population explosion, our industrial capacity can not meet the standard. "

"On the other hand, after a large population expansion, our current spaceship can't hold so many people In other words, after loading so many people, it seems not so comfortable. Many people have to live underground. When they can see the big ice hockey behind them with their own eyes, they will feel even more oppressive. "

"But..."

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

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

The congressman immediately retorted: "but that will lead to a serious aging and all kinds of problems. In an aging society, the labor force will be very scarce. Maybe even the elderly have to take part in the work and delay the retirement age! This will cause a lot of social problems! "

For a moment and a half, he fell into silence in the air. Either he spent more than 3000 years working slowly, and the future is hard to predict. Maybe it will take 4000 or 5000 years, or even give up halfway. Even if the new civilization historiography is powerful, it is impossible to predict the time of three thousand years.

Either cut half of the project, but may have to endure a long period of aging crisis, people are forced to complain.

Zhang Yuan shook his head and sighed, "nothing can be perfect. With a population of 100 million, we have to spend 400 years and work hard to improve our working hours. We have to complete about 40% - 50% of the work, and then we can only hand it over to future generations. "

"The fourth level civilization is not so simple. It always has to bear hardships."

"This whole set of projects will last for about 1400 years. So we can make an agreement with Huantai civilization that after 1400 years, we will rent some transport spaceships to transport our population to a place one light year away. Count in the past 100 years. It's 1500 years in all. "

"If a human fleet comes to the market after that, it can also send them information about curvature technology, or simply let them sell it in the market. Ah, if our civilization has not completed its plan and stopped its progress, then let the rest of mankind progress... "This kind of feeling is very bitter. We all know what Zhang Yuan is talking about

It makes a lot of sense.

But how should people choose?

Is it a plan that can be completed in 1400 years, or a plan that can last for 3000 or 4000 years?

This is the problem of long pain and short pain.

In 1400 years, we will certainly have to bear risks and suffer hardships. Even a hundred million people will have to suffer a lot in the face of huge quantities of work. For example, the daily working hours will be extended to 10 hours.

All kinds of less important occupations will be banned. People will no longer be able to play robot war games leisurely. The government will not be able to allocate resources to do these.

And the plan of three or four thousand years It's too long to plan. It is difficult to predict whether there will be conflicts with the tosian civilization and whether there will be greater variables.

It is also a question whether it can be done after planning.

In fact, Zhang Yuan doesn't believe that even if human beings finish the project, they can go further.

There are four levels of degenerate civilization in the galaxy
