Chapter 550
The counselor opened the mouth and said hoarsely: "Dear students, the distance between our planet and the big hockey puck at the back is about 202,200 kilometers, which is more than what was originally expected. 1.3% deviation. The distance shortened every ten years is about 10,000 kilometers..."
The two planets do not revolve around each other, but are arranged in a back and forth form on almost the same orbit. .
That is, the two neutron stars are moving around the center of mass of the two neutron stars together in an elliptical motion.
However, the gravitational force between planets is inversely proportional to the square of the distance. The closer the two planets are, the greater the gravitational force will be, which will speed up the approach between them.
Currently, the distance shortened every ten years is about 10,000 kilometers, but in the following ten years, it may be shortened by 11,000 kilometers, and so on, eventually getting faster and faster, until they collide.
"...So, we must maintain a stable construction speed and increase the driving force of the planetary engine to avoid collisions between planets."
Speaking of this, This time the special car for the social class finally reached the top of the mountain. People saw countless excavators digging in a large basin, and railroad trains transported and crushed these ore.
These ores are basically ordinary silicates and have no smelting value. They will become working fluids and sprayed out into violent plasma.
While Wang Haifeng and others, the future work is basically in this area. This project looks very simple, but it is actually very complicated. It starts from mining, then to transportation, and then It is crushed and finally turned into fuel.
A large-scale construction site requires a population of more than 100,000, the number of robots and various machinery, at least one thousand absolutely.
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 only robots that maintain machinery are still aging, complex production lines will produce various bugs, which require humans to deal with.
So after Wang Haifeng graduates, he will join the No. 009873 excavation working group and become a very precise screw, dedicating his life.
Their future has been planned.
Everyone's eyes are slightly dull, as if frozen, looking at the scene of in a frenzy in this large industrial base.
"Everyone, after this class, you are about to graduate... Do you have any questions you would like to ask?" the instructor at the university said again.
She is a hair grey-white old man who is still struggling at work.
Four hundred years ago, the population of the new human civilization swelled to 100 million.
The huge population has brought sufficient labor, so that in 800 years, humans have completed more than 80% of the planetary engines! For the remaining 600 years, only the remaining 20% needs to be completed.
However, with the passage of time, a large number of machines once purchased from the trading market began to depreciate. This is an overwhelming problem, so that the construction rate of planetary engines has gradually slowed down.
In addition, in the original agreement with the interstellar trading market, the future curvature spaceship can only carry a population of 40 million at most.
Therefore, the government intends to slowly recover from the current 78 million to below 40 million in the next 600 years.
As a result, changes in the demographic structure lead to the inevitable aging.
"teacher, can you change a job, a slightly more interesting job." Suddenly, a boy next to Wang Haifeng said. After he finished speaking, many students trembled.
Although this site is magnificent, but...Could it be that they will stay here for the rest of their lives?
"Of course, if you have enough professional knowledge, you can make construction machinery. We have many machinery that will be eliminated in the future. You can also go..."
"I am Say, more interesting work."
"Interesting, what is an interesting job?"
"For example, rap singing, drawing cartoons, programming games, etc... You can choose your own work "
The counselor is frowned, and then said with a smile: "In the past, when the entire plan had not been implemented, there were indeed many interesting laboratories where you could do your favorite work. But now, these laboratories have been banned. You can only engage in some scientific research work unless your grades are excellent to another level, or you can complete what you like in your spare time."
"After all, we These ordinary persons are all fighting for the greatest cause in the world."
All the students fell silent.
Suddenly, the boy said again: "The greatest career in the world is to use hundreds of thousands of excavators to dig this basin larger? Finally, the entire planet's surface is scraped off. Several hundred meters?"
The boy's tone is very strange, it seems to be a kind of mockery, but also with a hint of helplessness.
"Ah, yeah. This is the greatest career. My teacher taught me the same way. She dedicated her life like this, and so did I. Then, it's your turn. "
Unexpectedly, the counselor did not refute.
Perhaps she thought about it the same way when she was young, but she is old now and will retire soon, and she doesn't think about such complicated things anymore.
I've been here all my life, what else do you have to think about?
The students were silent and did not speak.
The next stop is the big hockey puck behind the buttocks of "Planetary Fortress". Everyone boarded the spaceship and headed to the big hockey puck numbered "JS144" 200,000 kilometers away.
The temperature of this ice ball is even lower. Below minus 250 degrees Celsius, the thick layer of ice is harder than steel. At this temperature, all the gas becomes thick. Of ice cubes.
There are also some industrial bases above the hockey puck. Hydrogen fuel, oxygen, methane and various chemical substances are being mined. As long as the ice cubes are cut by robots and simple purification, these substances can be obtained. Up.
lifts the head, Wang Haifeng saw the dreadful flame piercing the dark starry sky, as if it could hit their faces.
The planet in front of it blooming with multi-colored rays of light is the planetary fortress that they have exhausted their efforts to develop.
Because of the different atomic nuclei, the rays of light that bloom are different. Copper ions are blue, iron ions are yellow, and manganese ions appear pink. They cool down here. Condensed, and a large black haze was formed.
This planet chase battle will continue for at least four hundred years. Either mankind will win completely, or two planets will collide and fail completely. There will be no other results.
"Do you want to succeed or fail?"
Seeing this scene, everyone was silent, even the original angry boy looked at that one A planet full of multi-colored rays of light, speechless.
Some people thought of running away midway, escaping from this place, and abandoning the whole plan.
But they did not dare to speak out. Those brilliant ion flames seemed to ignite the entire civilization. Who dares to say escape, whoever is the sinner of history, the sinner of civilization.
Is it the greatest cause?
Who knows...
Who can define the so-called greatness?
To complete one's own work trembling with fear for a lifetime, is it great to be a screw of society?
No one can answer.
