Chapter 1101: Magnificent Space

Yang Chengwei listened to Zhao Zhongyao's words, and he was very excited. At the same time, he was very curious. Don't understand. How did Zhao Zhongyao know this knowledge, he had never been to space!

Yang Chengwei was a little puzzled by this matter, so he asked Zhao Zhongyao again: "Mr. Zhao, how do you know this knowledge, have you also been to space!"

Zhao Zhongyao listened to Yang Chengwei's words, smiled and said: "I have been to space, but I can imagine it! With some scientific knowledge, we can all imagine it." We scientists have never been to space, but we know a lot of space knowledge! Isn't this all reasonable speculation!"

Listening to Zhao Zhongyao's words, Yang Chengwei also understood how Zhao Zhongyao knew so much space knowledge. After all, is Zhao Zhongyao very knowledgeable? Of course, people know everything.

"Okay, if that's the case, then I'll hurry up and take a look at the beautiful scenery outside the porthole!" Yang Chengwei was also very happy when he heard Zhao Zhongyao say this, and he wanted to take a look at the beautiful scenery outside.

"Okay, then you can take your time! 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. Then when he returns, he will bring back some gifts for all mankind.

These gifts are the tasks he has to complete in space, which is to take a lot of pictures of outer space. After all, there are not many such opportunities. Not everyone can just fly into space.

Since Yang Chengwei has this opportunity, he must take a lot of photos and videos to bring back to the earth, so that the earthlings can also share the beautiful scenery he sees in space.

When Yang Chengwei's space capsule entered the shadow of the earth, the lights in the capsule automatically lit up. The whole capsule was very bright all of a sudden.

But it was bright inside, and it was pitch black outside. If he wanted to see the scenery outside, he had to dim the light inside the capsule.

So, according to his training on the ground, Yang Chengwei dimmed the lights inside. 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 brightly lit.

Such a spectacle can only be seen in space. The whole earth is like a giant globe. The land inhabited by humans is a very large map made of lights.

"It's so beautiful, it's a giant globe! I'm going to take a picture of it. Yang Chengwei looked at the huge globe outside, picked up the camera, and took pictures of the beautiful scenery.

After that, Yang Chengwei looked outside into space. In space now, it can be regarded as a brilliant light. Because, in space, there is no atmosphere to block it. The whole space was set against a dark background, and it was unusually bright. The stars, like the pearls of the night, shine brightly in space.

The entire galaxy is like a giant screen, hanging horizontally in space. In such an environment, the Milky Way can see not only one 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 she is growing up as a result of constantly devouring other small galaxies.

In space, as in nature. That's also where big fish eat small fish, and small fish eat dried shrimp. Large galaxies are not born big galaxies. Large galaxies are also constantly devouring small galaxies before they gradually grow.

It's the same with the Milky Way. It was also after constantly devouring small galaxies that it slowly grew into what it is now.

In fact, the entire galaxy we see in space is the same. The reason why we see a wide variety of galaxies. Just because they don't have the same volume. As a result, their shapes are different.

Generally speaking, the irregular galaxies we see are small galaxies. It's some galaxies that are just starting to grow. And galaxies like our Milky Way and the Andromeda Galaxy, like that, are medium-sized galaxies.

Such galaxies are generally spiral-shaped galaxies. That's why it's like this. This is because the galaxies they devour will be torn apart by the parent galaxy as soon as they enter the sphere of influence of the parent galaxy, and then turn into a star stream and begin to revolve around the parent galaxy.

Eventually, at one end of these streams, they enter the core of the parent galaxy. At the other end, it is still far away from the outer reaches of the parent galaxy. In this case, the star in the core moves faster. The outer stars move more slowly. The whole small galaxy is torn and running by the parent galaxy. As a result, these small galaxies become spiral arms of the parent galaxy.

And those irregular galaxies, because they are still in the early stages of growth. So, the small galaxies that they devour have not yet formed a stable shape on their periphery. Therefore, these small galaxies do not have a stable shape.

And some very large galaxies also have a stable shape, which is an elliptical shape. The reason why these large galaxies form such shapes. Because in general. These large stars are formed by the fusion of two or several medium-sized galaxies.

As two or more spiral galaxies merge together, the density of stars in the entire galaxy increases considerably. In this way, the spiral arms in the spiral galaxies that have been fused will not be able to see clearly. All the stars merge into a big circle. As a result, such a galaxy becomes an elliptical galaxy.

The typical example of this galaxy is the M87 elliptical galaxy, which is 60 million light-years away from Earth. The gravitational pull of this galaxy is so great that the Milky Way, tens of millions of light-years away, revolves around it.

But for all this, Yang Chengwei naturally can't see it. All he saw now was the beauty of our galaxy in space.

"Our galaxy is truly beautiful. I'm going to take some pictures. Yang Chengwei saw that the entire galaxy was like a silver light curtain. 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. And he saw a more beautiful scene. This is the moon that often lights up our night sky at night.

The moon in outer space is much more beautiful than what you see on Earth. Because there is no barrier from the atmosphere. The whole moon looks very bright. Even with the naked eye, it feels like you can see the criss-crossing ravines on the moon.

"The beautiful moon, I also saw it, I want to hurry up and photograph her. Yang Chengwei was very excited now, and hurriedly took pictures of the beautiful moon in front of him.

I asked him to pat it, and suddenly his eyes brightened again. The beautiful night scene disappeared all at once.

"Oh, it's daylight again! I've been so quick to spend the night. Yang Chengwei now knows that he has turned out of the shadows of the earth again. He put away the camera and stopped filming for the time being. After all, he has already photographed a lot of daytime landscapes.

In the daytime space, you can't see the stars in the sky, only the dazzling sun and the beautiful earth.

Yang Chengwei is very excited now. After all, this beauty is impossible to see on Earth. It is only in space that it is possible to see such a beauty.

In this way, Yang Chengwei traveled around the earth in outer space on this spaceship. He took a large number of unusually precious photographs. This is very helpful for earthlings to study the space environment.

Two days are about to pass, and Yang Chengwei has entered the night from day to night. He knew that after this night he had passed, he would be able to return to Earth. For him, this feeling of coming home is also very strong.

Although the beauty of outer space is breathtaking. But he knew that this was not a place to live for a long time, and that he belonged to Mother Earth. You can only live for a long time by returning to her arms. If you want to live in space for a long time, it can only be a matter of the future.

Because he was very excited, Yang Chengwei didn't feel sleepy for a day and a half, just kept shooting the beautiful and abnormal scenery outside.

But when the ship entered the shadows of Earth again, he felt a little sleepy. At this time, for Yang Chengwei, he had not closed his eyes for almost a day and a night. People get sleepy all the time, even in space.

Yang Chengwei is feeling a little sleepy now. He was thinking that in two hours, he would be back on Earth. Now I don't have anything to do. I did the work that should be done. Then take a nap for yourself!

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 else he had to do. Can you take a nap?

"Mr. Zhao, I'm feeling a little sleepy now! Can I take a nap. If there is, then I won't sleep. Yang Chengwei asked Zhao Zhongyao for instructions first.

Zhao Zhongyao listened to Yang Chengwei's words and smiled: "Of course you can." If you want to sleep, you can sleep for a while! Tomorrow, you're ready to go home!"

"Okay, then I'll take a nap!" Yang Chengwei said again.

Originally, Yang Chengwei wanted to ask about this matter, and it was fine. But Zhao Zhongyao asked with concern: "Cheng Wei, how do you feel now? Do you feel uncomfortable?" ”

Zhao Zhongyao also knows that astronauts are in space, and they are in a state of complete weightlessness. People in such an environment will be a little uncomfortable. After all, when people are on Earth, they live in a gravitational environment.

Life on Earth, after billions of years of evolution, has long adapted to the gravitational environment on Earth. If you suddenly let a living form enter a gravity-free environment, of course, it will be a little uncomfortable.

When people take the elevator, they will have the feeling of being overweight and weightless, and this feeling will make people uncomfortable! Some people who are not in good health may be dizzy when they take the elevator!

In space, it's almost a gravity-free environment. In such an environment, of course, it will also feel very uncomfortable. Only astronauts who have undergone rigorous training will be able to live in outer space. If you are an ordinary person, once you are in outer space, it will definitely make you dizzy and vomit and diarrhea.

Fortunately, Yang Chengwei has been on Earth for a long time and has been training in zero gravity. When he first started training, he felt the same way, he felt dizzy. It's just that after training for a long time, I slowly got used to it.

Yang Chengwei listened to Zhao Zhongyao's words, and said again: "Don't worry, Mr. Zhao, I feel very good now, and I don't feel any discomfort." ”

"Okay, if that's the case, then you can take a nap!" Zhao Zhongyao knew that if Yang Chengwei's body was normal, then of course he could sleep. If you don't feel well, it's best not to sleep. In outer space, it's a complex environment, and who knows what kind of problems you'll encounter when you're asleep.

"Okay, then I'll sleep for a while and get ready to go back. Yang Chengwei also said happily.

"Okay, I'll see you later. Zhao Zhongyao said and hung up the phone.

Yang Chengwei closed his eyes and wanted to rest.

But as soon as he felt like he was falling asleep. Suddenly, I heard a thudding sound, as if someone was banging on the door of a capsule in space. This frightened Yang Chengwei. He woke up from his dream at once.

"What kind of sound is this, what is it, banging on the capsule outside!"

Yang Chengwei lost his sleepiness all of a sudden. His eyes widened suddenly, looking at the capsule's door. He wondered what could be out there!

The sound stopped after two taps. But Yang Chengwei is no longer sleepy.

After all, it was an accident he couldn't have imagined. During the whole two-day flight, he felt that everything went so smoothly and there were no accidents. He just saw the magnificent scenery outside the capsule.

Originally, Yang Chengwei also thought that he could go back so smoothly soon. But what he didn't expect was that at this time, he actually heard a very strange thing. Even very scary sounds.

"What the hell is this sound, what is it pounding on my capsule. Is it an alien! Is he trying to talk to me?"
