Half-immortal civilization

During the entire Venus carnival, the Empire's ground control center was tense and busy.There are no flukes in science; you may find something now and then, but to understand it deeply, you have to invest too much effort.

These are the first few blurred pictures, but in the eyes of real scientists, they have extraordinary value, far beyond the value that ordinary people can see.Through these pictures, we can see the structure of this star system—how different it is compared to the solar system; see how many planets it has—whether it is stable or not. Before the following photos come, through a simple comparison of these photos, Roughly calculate the orbit and mass of the planet, etc.Through these photos, you can see the brightness, stability, approximate lifespan and so on of the star.

Give me a fulcrum, and I can pry up the whole earth!Such a statement is somewhat exaggerated.

But among scientists, as long as they master the most basic laws and rules, and a little bit of information, they can deduce the entire unknown system-the difference will not be particularly large!That's science.It is a discipline based on a solid foundation and accumulation!
And now, the team led by Zhang Chengye is starting to calculate these overnight.They were so excited they couldn't sleep at all!Exploring, discovering, and finally using the laws of nature is science, and once you sink into it, you will feel that indescribable passion.

Tick ​​tock... The clock moved forward silently, entering June 60, 6 in the Imperial Calendar, but everyone was already focused on the picture in front of them.From now on, the detector will send pictures almost every minute.The picture is getting sharper and of course getting closer, showing a picture of another star 2 trillion kilometers away from the sun!

"Look, this is a giant gaseous planet, estimated to be comparable in size to Saturn. Oh, this is the one I've found so far."

"They have five terrestrial planets. Oh my goodness, there are four orbiting within the range of Venus, the last of which is very ideal; and one approximately between the range of the Earth and Venus... oh Oh oh, no clearer pictures yet, but I'm sure. There's at least one planet with life. There might even be two!!!"

"There is no asteroid belt here, and together with the gaseous planets, a total of six planets have been discovered here. This is the first time that such a whole star system has been discovered outside the earth!"

It's early morning.The scientists are not asleep yet.The clearest photos will have to wait at least half a month.Wait until the detector goes inside.Now it's just a blurry picture.But their enthusiasm cannot be stopped!

Zhang Jingyuan picked up a printed high-definition fidelity picture. This exciting picture looks only two meters square.It's not small.But in this picture, there is only a star the size of a grain of rice in the middle, and there are a few invisible black spots around it. If you don’t pay attention, you might think it’s a problem with the paper itself—although the paper used here is all It is top notch and flawless.

But can so many things be judged by such a picture?Looking at the busy scientists, Zhang Jingyuan suddenly felt that he was a little out of touch with social reality!It can only be said that the current scientific development has surpassed Zhang Jingyuan's cognition.The speed of technological development and explosion is indeed overwhelming!When we were on Earth, who would have thought that building a spaceship would require blowing up a moon-like satellite for mining, and the spaceship itself is 117 kilometers long! 117 kilometers, not 117 meters!A whole man-made steel planet!

The receiver beeped continuously, and as the probe approached, more and more photos were taken, and when the sun came out in the morning, there was almost one photo every ten seconds.

At the same time, Imperial Synchronization sent the pictures without any processing to the Internet for people to download freely!This is the brilliance of the entire human civilization, as long as you can connect to the Internet, anyone can download it!Moreover, the superstring communication device sent these data to the earth in the first time.

But then the situation changed to updating photos every two hours, hundreds of photos at a time.The main reason is that the superstring communication device is always on, which consumes too much energy!The ones on the ground are okay, but the ones in space are troublesome; especially in the outer space of the solar system, which is about 300 billion kilometers away, there is almost no sunlight here, and the energy depends entirely on the nuclear fusion reactor carried by itself—yes, nuclear fusion , Imperial technology is advancing at a high speed; but even if it is a nuclear fusion reactor, after miniaturization, the energy output is not very high.

However, the citizens of the empire did not complain. In fact, the existing information is enough for people to study crazily for a long time.On the day of June 6 in the imperial calendar, except for a few necessary places such as transportation and medical treatment, most of the remaining positions are naturally on vacation.People shouted, cheered, and embraced wildly, and the planetariums in various places were full. People used radio astronomy telescopes to observe the distant stars in the constellation of Cetus.

Rich people take their own flying cars or flying saucers to space, rent the empire's space research base, and search for the future residence of human beings in an environment without atmospheric obstruction.

Before the real clear photos came, people frantically guessed what kind of planet it would be and what kind of race it would be?Is there any intelligent life that is close to human beings?Some people even picked up some sci-fi movies from the past.

But many people even make simple animated pictures and so on to satisfy their fantasies.

But when a picture was updated on June 6, the whole world was silent: two planets!Yes, in this starry sky, there are actually two planets that meet the standards of human beings!

A blue planet, there are several ant-sized artificial satellites in the sky, and a large barren area on the surface of the planet, but more of it is green land and blue sea!

However, people's shock is not over yet. Outside this planet, there is actually another planet. Although the mountains are covered with ice and snow, it still has a dense atmosphere and some strange plants! ! !

There is life!Planets with life!And yes: two! ! !

Soon, the official also gave specific exploration data.With more and more photos, scientists have more and more comprehensive information, and a completely digital whale constellation appears in front of people!

The light intensity of Cetus constellation is more than 45% of the sun, less than 50%; but because the fourth terrestrial planet is in an ideal position, life is flourishing on it, and the average temperature is about 17 degrees (Earth 15); while the fifth planet , although it is a bit far away, but if compared with the light, it is similar to that between the earth and Mars, and it is more in the orbital range of the earth. Although it is cold, the average temperature is about 5°, and there is a large amount of liquid water in the equatorial region. The same It's a nice place to live!
Li Changxing and the others looked at each other, and they all saw the surprise in each other's eyes.God is really kind to human beings!There is the moon and Venus next to the earth; there are two planets suitable for human life not far from the interstellar!Yes, 12 light years is very small in the universe.If the universe is the size of the earth, then 12 light years is a distance of several nanometers! ! !
However, only these data are not enough, and more are needed.

The first living planet has a diameter of 1.8 kilometers, a slightly smaller density, and twice the mass of the earth—and twice the gravity of the earth. With a little exercise, it can be used as an ideal place for immigrants.

The second planet of life is slightly smaller, with a diameter of 1.2 kilometers, more water, and a mass of about 0.9 times that of the earth. Of course, the same is true for gravity.If you ignore the temperature, this is ideal - come and live.

However, under the setting of the automatic program, the probe did not take too many photos of the No. [-] life planet. Under the attraction of electromagnetic waves and so on, it plunged into the No. [-] life planet!
Seeing this, the scientists were suddenly very disappointed. Sure enough, the machine was unreliable, and there was no flexibility at all. The No. [-] Life Planet took two photos!

But the next thing is interesting. As the Clairvoyance probe landed, it was first surrounded by some beings with live ammunition. There are two eyes that take up almost half of the face, the face is hairless, and the top of the head is of different colors-should it look like dyed hair?
And then there is a life wearing gorgeous clothes, constantly drawing and playing games in front of the detector, obviously it should be a nobleman or a high-level person in society.However, the final test of life intelligence is not very useful, because artificial satellites have been seen outside this planet, which is enough to show that this is a real planet with intelligent life.Hmm - the two living planets have no natural satellites, it may be a problem with the shooting angle.

But there is another function of entering the atmosphere, and that is to test the air!

Groups of data span 12 light-years back to Venus.

Oxygen content - 33%.so high!The citizens of the earth exclaimed that oxygen is a resource that human beings must pay attention to. Without water, you can live a healthy day; without oxygen, you can only live healthy for 30 seconds!
Carbon dioxide content - 2%, much higher than the Earth's content, but similar to Venus' carbon dioxide content, and somewhat lower.

Nitrogen content - 55%, yes, seems to be influenced by a wide range of physical structures, and other planets have similar elemental composition to the Earth group.

The content of toxic and harmful gases is 0.1‰, and the air quality is higher than that of the earth.

Water vapor content: The water vapor content at the detection site is 9%, and the air is very humid, even humid.However, the place where it landed was at 20° north latitude, which is understandable.

Atmospheric pressure - 1.78 standard atmospheric pressure, which is lower than the current pressure of Venus, which is completely acceptable.

Local gravity - 1.88 times the earth's gravity, a bit heavy, but it will take a while to get used to it, up to a year.Do not underestimate the ability of human evolution.

Local time: Calculate the surface speed, 20 hours a day, and the rotation is a bit fast.

Comprehensive evaluation: suitable for human habitation index: 80%, excellent! (Note: The earth is 90% - the percentage of 10% reduction in air pollution, oxygen content, population exceeding the standard, etc.) (To be continued..)
