Chapter 541

The instructor said hoarsely, "dear students, at present, the distance between our planet and the big ice hockey behind us is about 202210 kilometers, which is 1.3% deviation from the original estimate. The distance shortened every ten years is about 10000 kilometers.... "

The two planets do not revolve around each other, but are in almost the same orbit in a form of front and back arrangement.

That is to say, both sides make elliptical motion around the center of mass of the two neutron stars.

However, the gravitational force between stars is inversely proportional to the quadratic power of the distance. The closer the two stars are, the greater the gravitational force will be, which will speed up the approach between them.

At present, the distance shortened every ten years is about 10000 km, but in the following ten years, it may be shortened by 11000 km, and so on. Finally, it will get faster and faster until it collides with each other.

“…… Therefore, we must maintain a stable construction speed and increase the driving force of planetary engines to avoid collisions between planets. "

At this point, the special car for this big social class has finally reached the peak of the mountain. People can see that countless excavators are digging in a big basin, and rail trains are carrying away and crushing these ores.

These ores are basically ordinary silicates, which have no smelting value. They will become working fluids and violent plasma jets.

The future work of Wang Haifeng and others is basically in this aspect. This project looks very simple, but it is very complicated in reality. It starts from mining, then transportation, then crushing, and finally turning into fuel.

A large construction site needs more than 100000 people, robots and various machines, at least more than 10 million.

Although most of the work is automated, there will always be some mechanical failures and mechanical maintenance to be done.

The aging of parts is an inevitable problem in the universe, even if the maintenance of machinery can only be robot, it will still be aging, complex production lines will produce a variety of bugs, which need human to deal with.

Therefore, after graduation, Wang Haifeng will join the No. 009873 excavation working group, become a very accurate screw and devote his life.

Their future has been planned.

Everyone's eyes slightly dull, as frozen general, looking at this large industrial base, hot scene.

"Everyone, after this class, you are going to graduate Do you have any questions to ask? " Said the counselor in the University.

She is a gray haired old man, and she is still working hard.

Four hundred years ago, the population of new human civilization expanded to 100 million.

The huge population has brought enough labor force, so that in 800 years, mankind has completed more than 80% of the planetary engine! For the remaining 600 years, only the remaining 20% needs to be completed.

However, with the passage of time, a large number of machines that had been purchased from the trading market began to depreciate, which was a problem that could not be overcome, so that the construction rate of planetary engines gradually slowed down.

In addition, according to the original agreement with the interstellar market, the curvature spacecraft in the future can only carry 40 million people at most.

Therefore, the government plans to slowly recover from the current 78 million to less than 40 million in the next 600 years.

In this way, the change of population structure leads to the inevitable aging.

"Teacher, can you change a job, a little more interesting job?" Suddenly, Wang Haifeng side a boy said. After he finished, many students shook their bodies.

Although this site is spectacular, but Do they stay here all their lives?

"Of course, if you have enough professional knowledge, you can manufacture construction machinery. Many of our machinery will be eliminated in the future, and you can also..."

"I mean, more interesting work."

"Interesting. What is interesting work?"

"For example, singing, drawing comics, programming games and so on You can choose your own job. "

The counselor frowned and then said with a smile, "before the whole plan was implemented, there are many interesting laboratories where you can do what you like. But now, these laboratories have been banned. You can only engage in some scientific research work unless your achievements are excellent to another level. You can also complete what you like in your spare time. "

"After all, we ordinary people are fighting for the greatest cause in the world."

All the students were silent.

All of a sudden, the boy said: "the greatest cause in the world is to use hundreds of thousands of excavators to dig the basin bigger? And finally scrape the surface of the whole planet off a few hundred meters? "

That boy's tone is very strange, seems to be a kind of irony, but also with a trace of helplessness.

"Ah, yes. This is the greatest cause, at the beginning, my teacher also taught me. So she gave her life, and so did I, and then it's your turn. "Unexpectedly, the counselor did not retort.

Maybe she thought so when she was young, but now that she is old and will retire soon, she will not go back to think about such complicated things.

I've been here all my life. What else can I think of?

The students were silent and did not speak.

The next stop is the big ice hockey behind the "Planetary Fortress". All the people take the spaceship and go to the big ice hockey named "js144" 200000 kilometers away.

The temperature of the ice ball is lower, below minus 250 degrees Celsius. The thick ice is harder than steel. At this temperature, all the gases form thick ice.

There are also some industrial bases above the ice hockey, which are mining hydrogen fuel, oxygen, methane and all kinds of chemical substances. As long as the ice is cut down by robots and simply purified, these substances can be obtained.

Looking up, Wang Haifeng saw the trembling flame cutting through the dark starry sky, as if he could pounce on their faces.

In front of that a blooming colorful light of the planet, is that they try their best to develop the Planetary Fortress.

Due to the different nuclei, the intense plasma light is also different. Copper ions are blue, iron ions are yellow, and manganese ions are pink. They cool and condense again here, forming a large black haze.

This planet chasing war will last for at least 400 years. Either mankind will win completely, or two planets will collide and lose completely. There is no other result.

"Do you want to succeed or fail?"

Seeing this scene, everyone was silent. Even the aggrieved boy, looking at the colorful planet, could not speak.

Some people think of running away, fleeing the place and abandoning the whole plan.

But they didn't dare to say it. Those brilliant ion flames seem to light the whole civilization. Whoever dares to run away is the sinner of history and civilization.

The greatest cause?

Who knows

Who can define greatness?

Is it great to finish your own work in a lifetime and be a social screw?

No one can answer.
