Chapter 1074: Magnificent space

The first thousand and one chapters magnificent space
Yang Chengwei was very excited when he heard what Zhao Zhongyao said. At the same time, he is also very curious. do not understand. How did Zhao Zhongyao know this knowledge? He has never been in space!
Yang Chengwei couldn't understand this matter, so he asked Zhao Zhongyao again: "Mr. Zhao, how do you know this knowledge? Have you been to space too!"
After hearing Yang Chengwei’s words, Zhao Zhongyao smiled and said, "I have been to space, but I can imagine it! With some scientific knowledge, we can all imagine. We scientists have never been to space, but Know a lot of space knowledge! Isn't this all a reasonable guess?"
After hearing what Zhao Zhongyao said, Yang Chengwei also understood how Zhao Zhongyao knew so much space knowledge. After all, is Zhao Zhongyao knowledgeable? Of course they know everything.
"Well, if this is the case, then I will quickly look at the beautiful scenery outside the porthole!" When Yang Chengwei heard Zhao Zhongyao say this, he was very happy, and wanted to quickly take a look at the beautiful scenery outside.
"Okay, then you can enjoy it slowly! Don't forget to take some more pictures." Zhao Zhongyao said to Yang Chengwei again.
For Yang Chengwei, he flew into space on behalf of all mankind this time. After he returns, he wants to bring back some gifts to all mankind.
These gifts are his mission in space, which is to take a lot of pictures of outer space. After all, such opportunities are rare. Not everyone can fly into space casually.
Since Yang Chengwei has this opportunity, he must take a lot of photos and videos to bring back to the earth, so that the people on earth can also share the beautiful scenery he saw in space.
When Yang Chengwei's space capsule entered the shadow of the earth, the lights in the space capsule automatically turned on. The entire space capsule is suddenly very bright.
But the inside is bright, and the outside is completely dark. If he wants to see the scenery outside, he must darken the light inside the capsule.
Therefore, Yang Chengwei dimmed the light inside according to his training on the ground. Then he looked out of the porthole.
This time, he saw the beauty of the earth. The whole earth seems to be a big lantern. Except for the darkness in the ocean, the entire continent is full of brilliant lights.
Such a spectacle can only be seen in space. The whole earth is like a huge globe. On the land where humans live, there is a very huge map composed of lights.
"It's so beautiful, it's a giant globe! I want to quickly take pictures of this beautiful scenery." Yang Chengwei looked at the giant globe outside, so he picked up the camera and took pictures of the beautiful scenery. Come down.
After that, Yang Chengwei looked towards the outer space. In the space now, it can be regarded as brilliant. Because there is no barrier from the atmosphere in space. The whole space is very bright against the backdrop of a black screen. The stars are like night pearls, and the space is shining brightly.
The entire galaxy is like a huge screen, hanging horizontally in space. In such an environment, the Milky Way can not only see a single screen, but also several spiral arms of the Milky Way.
In fact, the reason why the Milky Way is the way it is now is because of her constant devouring of other small galaxies as she grows up.
In space, it is like in nature. That's also where big fish eat small fish and small fish eat dried shrimps. Large galaxies are not born to be large galaxies. Large galaxies are also gradually growing in the midst of constantly devouring small galaxies.
The same goes for the Milky Way. It was also after continuously devouring small galaxies that it slowly grew into what it is now.
In fact, the galaxies we see in space are all the same. The reason why we see all kinds of galaxies. Just because of their different sizes. This led to their different shapes.
Generally speaking, the irregular galaxies we see are small galaxies. Some galaxies are just beginning to grow. And galaxies like our Milky Way and Andromeda Galaxy are all medium-sized galaxies.
Such galaxies are generally spiral galaxies. The reason is like this. The reason is that the galaxies they swallow will be torn apart by the parent galaxy when it enters the sphere of influence of the parent galaxy, and then it will become a star stream and begin to revolve around the parent galaxy.
Finally, one end of these star streams will enter the core of the parent galaxy. On the other end, it is still far away from the parent galaxy. In this case, because the stars in the core move faster. The outer stars move slowly. The entire small galaxy tore the mother galaxy to revolve. As a result, these small galaxies have become spiral arms of the parent galaxy.
The irregular galaxies are still in the early stages of growth. Therefore, the small galaxies that are swallowed by them have not yet formed a stable shape on their periphery. Therefore, these small galaxies have no stable shapes.
And some very large galaxies also have a stable shape, which is an elliptical shape. The reason why these large galaxies form such a shape. Because in general. Such large stars are formed by the fusion of two or several medium-sized galaxies.
As two or several spiral galaxies merge together, the density of stars in the entire galaxy increases a lot. In this case, the spiral arms in the fused spiral galaxies will be unclear. All the stars merged into a big circle. Thus, such a galaxy becomes an elliptical galaxy.
The typical representative of this kind of galaxy is the M87 elliptical galaxy 60 million light-years away from the earth. The gravity of this galaxy is so huge that the Milky Way galaxy tens of millions of light-years away will revolve around it.
But for all this, Yang Chengwei naturally can't see it. What he sees now is only the beautiful appearance of our Milky Way galaxy in space.
"Our Milky Way is really beautiful. I want to take some pictures." Yang Chengwei saw the entire Milky Way as a silver screen. So, I quickly picked up the camera and filmed this beautiful scene.
Just when Yang Chengwei felt that the space at night was very beautiful. He saw a more beautiful scene. This is the moon that often illuminates our night sky at night.
The moon in outer space is much more beautiful than the one seen on the earth. Because there is no barrier from the atmosphere. The entire moon looks very bright. Even with the naked eye, it makes people feel that they can see the criss-cross ravines on the moon.
"I have seen the beautiful moon, too. I want to quickly take a photo of her." Yang Chengwei is very excited now, and quickly took another photo of the beautiful moon in front of him.
Asking him to pat, suddenly his eyes brightened again. The beautiful night scene suddenly disappeared.
"Hey, it's daytime again! I passed this night really fast." Yang Chengwei now knows that he has turned out of the shadow of the earth again. He put away the camera and is not shooting for now. After all, he has taken a lot of daytime scenery.
In the daytime space, you can't see the sky full of stars, only the dazzling sun and the beautiful earth.
Yang Chengwei is very excited now. After all, this beauty is impossible to see on earth. Only in space can you see such a beautiful scenery.
In this way, Yang Chengwei traveled around the earth in outer space on this spacecraft. He took a lot of unusually precious photos. This is very helpful for people on earth to study the space environment.
Two days were about to pass, and Yang Chengwei entered the night again from daytime. He knew that after he had passed the night this time, he could return to the earth. For him, the feeling of going home is very strong.
Although the beauty of outer space is so beautiful. But he knew that this was not a place to live for a long time, he belonged to Mother Earth. Only return to her arms to live a long time. If you want to live for a long time in space, it can only be a future thing.
Because of his excitement, Yang Chengwei was not drowsy during this day and a half, he was constantly shooting the beautiful and unusual scenery outside.
But when the spacecraft entered the shadow of the earth again, he felt a little sleepy. At this time, for Yang Chengwei, he hadn't closed his eyes almost all day and night. People are always sleepy, even in space.
Yang Chengwei feels a little sleepy now. He was thinking that he would return to Earth in two hours. Now that there is nothing wrong with me. The work that should be done is done by myself. Then just take a nap!
So Yang Chengwei wanted to sleep for a while. Before going to bed, he also asked Zhao Zhongyao. After all, he didn't know what tasks he still had. Can I take a nap?
"Mr. Zhao, I feel a little sleepy now! Can I take a nap? Are there any tasks left! If there is, then I won't sleep." Yang Chengwei first asked Zhao Zhongyao for instructions.
After hearing what Yang Chengwei said, Zhao Zhongyao smiled and said, "Of course. You can sleep for a while if you want to sleep! There is nothing wrong. Tomorrow, you are ready to go home!"
"Ah! Okay, then I'll take a nap!" Yang Chengwei said again.
Originally, Yang Chengwei wanted to ask this matter and it was all right. But Zhao Zhongyao asked with concern: "Cheng Wei! How are you feeling now! Do you feel uncomfortable?"
Zhao Zhongyao also knew that the astronauts were in space and were in a state of total weightlessness. People will be a little uncomfortable in such an environment. After all, people are on the earth and they live in an environment with gravity.
After billions of years of evolution, life on Earth has long adapted to the gravity environment on Earth. If a living body is suddenly allowed to enter an environment without gravity, of course it will be a little uncomfortable.
When people take the elevator, they will feel overweight and weightless. Such feelings will make people uncomfortable! Some people with poor health may be dizzy if they take an elevator!
In space, it is almost an environment without gravity. People in such an environment will of course feel very uncomfortable. Only astronauts who have undergone severe training can live in outer space. If an ordinary person arrives in outer space, it will definitely make you dizzy and vomiting.
Fortunately, Yang Chengwei is already on the earth and has been training in zero gravity for a long time. He was the same when he started training, he felt dizzy. It's just that the training time is long, so I gradually adapt.
Yang Chengwei heard what Zhao Zhongyao said, and said again: "Don't worry! Mr. Zhao, I feel very good now, and there is no discomfort."
"Well, if that's the case, then you can take a nap!" Zhao Zhongyao knew that if everything in Yang Chengwei's body was normal, then of course he could sleep. If you feel uncomfortable, it is best not to sleep. In outer space, it is a complicated environment, who knows, what kind of problems you will encounter when you fall asleep.
"Okay, then I'll sleep for a while and prepare to go back." Yang Chengwei also said happily.
"Okay, see you later." Zhao Zhongyao said and hung up the phone.
Yang Chengwei closed his eyes and wanted to rest.
But when he just felt that he had fallen asleep. Suddenly I heard a banging sound, like someone knocking on the door of the space capsule in space. This scared Yang Chengwei. He woke up from his dream all at once.
"What sound is this, what is it, knocking on the capsule outside!"
Yang Chengwei lost his sleepiness at this moment. His eyes widened suddenly and he looked at the door of the space capsule. He was thinking, what would be outside!
After beating twice, the sound stopped again. But Yang Chengwei has no sleep anymore.
After all, this was an accident he couldn't think of. During the entire two-day flight, he felt that everything was so smooth, no accident happened. He just saw the magnificent scenery outside the capsule.
Originally, Yang Chengwei also thought that he could go back quickly and smoothly. But what he didn't expect was that at this time, he heard something very strange. Even a very scary voice.
"What the is this, what is beating on my capsule. Is it an alien? Does he want to come and chat with me!"
