Chapter 41: The Great Population Migration
The erosion of time is the most cruel, escape or cherish, it will not have any change with the will of man. A hasty and busy six months passed quickly, and even delayed a few more days, but people space engineering must be finished.
Professor Thomson, who was in charge of astronomical observations, had issued several warnings in succession that several large meteorites were beginning to cross the Lagrangian limit and had a high probability of striking the Moon, and that man must leave immediately!
These meteorites and the Moon are attracted to each other, creating a complex multi-body motion. This motion is extremely sensitive to initial values, called chaotic phenomena, and it is difficult for humans to get an exact solution. But the dangers involved are real, and the sooner you leave the sooner you are safe.
In the heart of Oliver, the captain of the Noah, there is a strong and complex emotion of parting, human beings, about to leave their homeland, most likely forever, never to return. This is also the thought in the minds of many people, in their work, often flowing a flash of melancholy feeling.
But there is nothing to be done about it. Mankind must step into the universe and find its own sky.
From the perspective of the satellite, you can see that the entire base has been greatly changed. The original round glass cover has long been removed, replaced by a huge deep pit, a silver-white orb is lying quietly in the center of the pit.
It was none other than the last home of mankind - the Noah!
It was too big, too spectacular, a sphere fifteen kilometers in diameter, seven and a half times longer than the original base, occupying half of the entire crater. Disregarding other technologies, just such a large size is not something humans can do.
The tallest human building, the Burj Khalifa, with a height of 828 meters, is only one-eighteenth of it, and can be said to be just a small dot. The two shapes, the round sphere as well as the cone, represent different technological contents, and the round ship is the most difficult to build.
Its surface is almost completely smooth, which means that there is very little friction, so no dust can get on the surface of the hull, and the whole ship looks shiny and has a kind of beauty that shakes the heart.
But because there is no friction, and hard enough to give people a certain difficulty in construction, what cement, paint, there is no way to directly paste up. No friction, a smear on the fall, even the most powerful human glue is no exception.
Smart scientists came up with another way, the outside can not be built, but inside can ah, people in the ship built a large number of thick cement pillars, and then the steel and cement from the entrance and exit of the ship extended out.
By relying on these extended structures, people indirectly built a lot of things on the surface of the ship. Like the engine room, cockpit, observation room, and some laboratories, etc.. These subsidiary structures are made of titanium and aluminum alloy, very light, yet hard and reliable.
Oliver was even a little glad that the ship had more than two thousand entrances and exits. Without these, there would be no way for humans to even build anything on the surface of the ship.
This is the difference between heaven and earth in technology.
The civilization that built this ship, humans really can't imagine its level of development. Humans, in front of this super civilization, might really be similar to a straw worm.
It must be said that this is a pessimistic thought, but also the truth, in the face of the vast universe, human beings are still too young ah.
The bottom of the ship's "engine" is a bit like a large washbasin. But this "basin" is upside down, sealed inside a large amount of gas, as well as a - a billion tons of helium-3 nuclear bomb!
The diameter of the basin is about one kilometer, and this volume is carefully calculated, too big is not good, too small is not good. Do not think that the ship is fifteen kilometers in diameter, the engine is only so little, the mass of the ship is really too light compared to its volume, and the overall density is worse than a balloon.
So, such a small engine is also enough.
All the instruments are doing the final test, hundreds of testers in spacesuits are busy.
Oliver toured the warehouse again, billions of tons of ore piled up like a small mountain in the ship, the entire uranium resource mine is almost all dug up, enough for human use for 20 to 30 years. The ice resources at the bottom of the ship were also mined, and about 100 million tons of ice were obtained. The remaining food is also enough for humans to eat two or three years.
But Oliver still felt that it was not enough, he always had a feeling of insecurity. Perhaps, this is a common feeling in the hearts of all people, the vast space, mankind will not get any material replenishment, how much more is not enough ah.
It's like when a wanderer leaves his mother for the first time, he will always carry a big bag of things, well-prepared, but still nervous.
If everything goes well, three or four months to Mars, when people can get resources to replenish, can not be so nervous ah.
Oliver reassured himself and continued his inspection.
From the inside, the entire ship facilities can only be said to be poor. Because of the gravity, the entire living area is divided into three parts: upper, middle and lower. The top of the lowest gravity, about the same as the moon, the bottom is the Earth's gravity.
This is because people have not yet adapted to the relationship of the Earth's gravity. In this low-gravity environment on the moon, used to living, the calcium in the bones will gradually lose, the muscles will gradually atrophy, if a moment to reach the Earth's gravity zone, often with paralysis, completely unable to stand up.
Therefore, people need to have a gradual adaptation process, the first batch of people relocated in, has been fully adapted to the Earth's gravity environment.
As for people's living environment, can not say very good, after all, six months is too short a time, people can not go to build any high-rise buildings. Necessary life-support equipment, such as oxygen circulation system, water circulation system, power system, sewage treatment system, the construction of these things will take a lot of time, there is no work to improve the living environment ah!
Do not suffer from the scarcity of uneven, in order to prevent such and such a broken thing, Oliver simply a wave, all sleep in tin houses, even he himself is no exception.
This simple and easy to do the house, a few pieces of tin a round, that is, the construction site workers often sleep in the kind of, can not say comfortable, and not much sound insulation, but at least can cover some.
For this phenomenon, no one has any complaints, the captain Oliver himself are living in this kind of house, what else can say? Are you more powerful than the captain of the Noah's Ark?
By the way, the name of the ship is called Noah, because its from the Hebrew Bible? The story in Genesis, which means the ship that saves the world. And this time, it is also the ship that saves mankind.
"Report Captain! Engine system check completed, no errors found, please instruct!"
"Report captain! Power system check is complete, no errors found!"
"Captain, all the people have been arranged for accommodation."
...
One by one, the test reports came up and no abnormalities were found. It's time to leave, ah, Oliver tapped his fingers on the table, said emotionally, "You go broadcast a notice, from now on, all people are free to move around, stranded on the ground no longer than 12 midnight."
"Tomorrow at eight o'clock, officially set sail!"
"Yes!"
With this announcement, a large group of people got off the ship. They were wearing space suits, walking on the moon, some taking pictures of the ship, some taking pictures of each other, and some sketching, having a good time.
People knew that the time to stay on the moon would never come back, so they cherished it extraordinarily, it was the last memorial.
