Chapter 537 It’s probably the second earth

Arc star.

Dong Chen named that second earth Arc Star.

He feels uncomfortable now if his name doesn't have something to do with "Arclight".

"Arclight Star" sounds so good. It not only declares ownership, but also is easy to remember. The most important thing is that you don't have to think of a name from scratch, which will hurt your brain.

The new galaxy is also called the Arc Galaxy, and the names of each planet from the inside to the outside are called Arc 1, Arc 2, Arc 3... and then all the way up to Arc 7.

This is Dong Chen's official name. As for the specific name, I haven't thought about it yet. I only named the most conspicuous life planet, and it is not much different from the overall name...

"Forget it, that's the name. It's just a code name. Don't worry about it. Don't worry about it."

Dong Chen always comforted himself like this.

Since the four unmanned detection spacecraft have entered, he has received a lot of news in the past few days, and this news makes him more and more excited, but it also makes him more and more doubtful.

This red giant is 232 billion years old. It can be said to be older than the age of the sun. However, it only took less than 2 billion years to become a red giant. It is only in the main sequence stage. It has been around for more than 200 billion years, but its mass is much smaller than that of the sun, which is understandable.

But for such a long time, the civilization of this galaxy has not developed. This shows how lucky the earth is.

The Arc Star is smaller than the Earth, its diameter is only 80% of the Earth's, and its gravity is about 0.94 times that of the Earth. However, it has two satellites, but compared to the Earth's satellites, their size ratios are much normal.

However, they are still very bright in the night sky of arc stars. Although the brightness of a single star is not as bright as the moon, when both are in the sky, they are much brighter than the moon, at least 15% brighter.

The two satellites are one big and one small, with the smaller one orbiting closer and the other orbiting farther away, so on the arc star it looks like the smaller satellite is larger and the larger satellite is smaller.

They are all tidally locked by the arc star, with one side always facing the arc star, and they also cause the tides on the arc star to change differently from those on the earth, even to the point where the two satellites are on the same side of the arc star, and are directly connected to the arc star. There is also a strong tide when we line up in a straight line.

One rotation of an arc star is equivalent to twenty hours on earth, which is equivalent to twenty hours in an arc star day, and one revolution around the red giant star is equivalent to four hundred days on earth. If calculated according to arc star time , that is, one revolution takes 480 arc days.

Its temperature is slightly higher than that of the earth, and its humidity is slightly higher. Its four seasons are similar to those of the earth, but its air composition ratio is not suitable for human survival.

Although it is mainly nitrogen and oxygen, its oxygen content reaches 25%. The ammonia and chlorine in the air are much higher than those on the earth. The content of various rare gases is also higher than that on the earth. Human beings will leave if they are not protected. GG is not far away.

Knowing this information, Dong Chen knew how excellent No. 1's proposal was. If he really had to wear a spacesuit when he got there, even if he didn't wear a spacesuit, then an air filter mask would definitely be indispensable.

That would be too inconvenient, so a mechanical double would be better.

What surprised Dong Chen was that the creatures on the Arc Star, or directly speaking, intelligent creatures, turned out to be similar in size and appearance to humans.

In addition to intelligent creatures, the animals and plants on the Arc Star are 70% similar to the animals and plants on the Earth. Although the appearance is not exactly the same, they also have some strange animals and plants that are completely different from the Earth, but many things can See the shadows of plants and animals on Earth.

This is a little strange.

The two galaxies are separated by who knows how many light years. They can't see each other at all, and the air composition is so different. How can these intelligent creatures be similar?

I couldn't figure it out in a short time, but Dong Chen suspected that this might be related to the wormhole. Maybe humans and Arclight people are related three generations apart, so it would be right to call Arclight Star the second earth.

This is called five hundred years ago, it was one... uh, five thousand... fifty thousand... it was one family 3.7 billion years ago.

But there is no rush on this matter. After all, billions of years have passed, and it is not less than the past few years, so he just asked No. 1 to record this issue. When he has time, he will deal with it carefully. and verified.

After observation, Dong Chen found that the level of civilization development of the Arclight people was not high. It looked a bit like a primitive tribe and a bit like a slave society, but it was a bit strange. The development stages in various places felt very uneven and a bit chaotic.

Their level of metal smelting seems to be very high, and some of the buildings look strange and unlike what they should have at this stage.

Just when Dong Chen was wondering, Arclight 3 Star gave him the answer.

Guguang 3 is the planet closer to the red giant than the Arc star. It is similar to Mars in the solar system, but the Arc star is larger than Mars and has a thicker atmosphere than Mars.

Although it was basically covered by yellow sand, the detection spacecraft still found some architectural ruins on it, and there were quite a few of them.

After combining the situation of this galaxy and looking at the expanding red giant star, Dong Chen knew the situation.

It should be that as the parent star of this galaxy expanded, the habitable zone for animals in the galaxy moved to the outside. The planets that were originally suitable for survival inside were no longer suitable for survival, and it became what it is now.

The planet that was originally outside the habitable zone for animals moved into the habitable zone and became a beautiful planet suitable for the survival of Arc-Light people.

Moreover, Dong Chen also felt that the Arc Light people on Arc Light 3 were not necessarily the First Age civilization of this galaxy. After all, this galaxy had existed for too long.

Theoretically, and only in theory, if we follow the development model of civilization here on Earth, those with advanced civilizations would have wandered into the universe long ago.

The more Dong Chen looked at it, the more he felt that there were many secrets in this galaxy that could be mined, but he was not in a hurry right now, since he was the only one who knew about it.

Moreover, the stand-in robot is still being upgraded, its dedicated small unmanned spacecraft is also being built, and the equipment it may use on the arc star is also being manufactured.

Dong Chen's Black Hawk is also being upgraded. After all, he is going to take the Black Hawk to the wormhole to absorb energy and then open his third game world. He has been waiting for this day for a long time.

But to implement this plan, he would have to float in space for a long time. After all, there are two planets between the wormhole and the earth.

Even if the energy concentration can be charged in advance halfway, it will still take 20 days to start. It will not work if the Black Hawk's cargo warehouse is not converted into a living cabin.

Therefore, we still need to get things done on Earth first, and there are a lot of things happening on Earth these days.

A few days passed, and the time came to June 2020. Under the ultra-fast construction speed of the Arc Light Group, the complete New Tiangong Space Station was finally built.

With a body length of one thousand meters, coupled with the two gravity simulation cabins with a diameter of 500 meters, its huge body lies across the orbit of the earth, and it looks so majestic.

At the overall completion ceremony, Dong Chen and a group of guests and reporters no longer had to stand in space or stay in the plane, but gathered in the reception hall.

The reception hall belongs to the Arc Light Group and is a public area. It has been renovated by the Arc Light Group. It is also a viewing location, with one side facing the earth and the moon and space visible on the other.

By holding a press conference in such a place, the Arc Light Group's reputation is really high.

Those guests who were invited to come were better off. The invitation letters from the Arc Light Group were sent directly to them, so there was nothing to argue about.

The reporters who were invited to come were different. Arc Light Group sent the invitation letter directly to their company. As for who they sent, Arc Light Group didn't care. Arc Light only reserved seats here.
