Chapter 1761 Looking for the Oasis of Life

After hearing Tiantian's words, Feifei smiled and said, 'Sister, what are you talking about! Don't worry about Dad's driving skills! '

After hearing what my brother said every day, I smiled and said, 'I'm not worried about my dad's driving skills, I'm just worried that the sun's gravitational force is too strong, and our spaceship can't resist it at all. '

After listening to my sister's words every day, I smiled and said, 'Sister, although the sun is very big, its gravitational force is also very strong. But the gravitational force between two objects is determined by the mass of the two objects. If two objects are both very massive, the gravitational force between them is also very large. Just like the gravitational force between the planets. Because of their great mass, the gravitational force between them is also great.

But our spacecraft is really too small compared to the sun. The gravitational force of the sun is very strong, but the gravitational force exerted on the spaceship is very small. Even if we are very close to the sun, we don't have to worry about being sucked by the sun. Of course, this is still relative. If it is really very close to the sun, it is also possible for the sun to be sucked past.

This is like our human aircraft in space. As long as it is a few hundred kilometers away from the earth, it will be subject to very small gravitational force, and it can hardly be affected by the gravitational force of the earth. But when you are only tens of kilometers away from the earth, you will be subject to a great gravitational pull from the earth. This gravitational force is not only related to the mass of objects, but also related to the distance between objects. '

Hearing Feifei's words every day, he smiled and said, 'Brother, do you feel that I never went to school? You are still showing these ordinary physics knowledge in front of me. '

Feifei smiled and said, 'I'm not showing off, I just feel that you haven't gone to school for the past few months, it seems that you have forgotten these common knowledge. '

When Feifei and Tiantian were talking like this, Zhao Zhongyao had already flown near Mercury by driving the spaceship.

At this moment, Zhao Zhongyao looked at Feifei and Tiantian and said, "Stop arguing, you two, our spaceship won't be attracted by the sun." But it's quick to let Mercury gravitate past. '

'Dad, we're on Mercury so soon. '

Feifei saw a huge planet floating in the space not far ahead, he immediately didn't want to talk about physics with Tiantian, he wanted to appreciate the Mercury in space.

'Of course, how fast our ship is. We flew from Venus to Mercury in just over an hour. Zhao Zhongyao said so.

‘Dad, let’s fly to the sky above Mercury to have a look! I just want to see what this planet looks like. ’ Feifei is very interested in the Mercury in front of him, and wants to see what it looks like on Mercury.

'Well, let's go to the front of Mercury first! With sunlight on the front, we can see what the surface of Mercury looks like. Zhao Zhongyao said so.

'Okay, let's see what the front of Mercury looks like first. ’ Feifei also said the same.

Soon, Zhao Zhongyao drove the spacecraft to a place hundreds of kilometers above Mercury. From this place one can see the surface of Mercury above.

Zhao Zhongyao is now driving the spaceship and starts flying in front of Venus. Feifei, Tiantian and Qu Yuqian also began to observe the surface of Mercury very curiously.

'Dad, does this Venus look similar to the moon! Just some craters. Apart from these craters, there is no other special terrain. ’ Feifei looked at the impact craters on the surface of Mercury below, and he felt that the surface of Mercury is very similar to the moon.

'Yes, the surface of Mercury is very similar to that of the Moon. However, this is only the positive side of Mercury. The front side of Mercury is very similar to the surface of the Moon. But the back of Mercury is different from the top of the moon. Zhao Zhongyao said so.

'Why, what's the difference. ’ Feifei still didn’t understand.

‘North of Mercury is a dark world. Since Mercury keeps the sun tidally locked. The face of Mercury is always facing the sun. Its back is always facing away from the sun. What the backside of Mercury really looks like. No one knows yet! Zhao Zhongyao said so.

‘Dad, shall we go to the back of Mercury to see. ’ Said Feifei.

'Of course, we'll go to the back side of Mercury in a bit. The face of Mercury is actually not much to look at. ' Zhao Zhongyao said.

After finishing speaking, Zhao Zhongyao drove the spacecraft in front of Mercury again. Only when they got to a huge crater. Zhao Zhongyao said again, ‘This is the largest impact crater on Mercury. It is now the hottest place on Mercury. This impact crater may have been formed by an asteroid impact two billion years ago. It was the impact of this asteroid that made the crust and mantle on the surface of Mercury disappear. That leaves an iron-rich core. '

After hearing Zhao Zhongyao's words, Feifei, Tiantian and Qu Yuqian looked at the huge crater below together. They feel that this crater is really huge, even if they are hundreds of kilometers away from the surface of Mercury. But it can still be felt that this crater is very large. And they are flying over this huge crater.

‘Dad, does this crater have a name! What is the name of this crater. Feifei looked at Zhao Zhongyao again and asked.

After hearing Feifei's words, Zhao Zhongyao said, "Of course, such a big crater naturally has a name." It's called a calorie crater. '

After hearing what Zhao Zhongyao said, Feifei said strangely

, 'Dad, what did you say, it's called a calorie crater, is it what we call a calorie unit calorie! '

After hearing Feifei's words, Zhao Zhongyao said,'That's right, it's the calorie of the calorie unit calorie. '

'Oh, that's true. Then why call it such a name! ’ Feifei said again puzzled.

After hearing what Feifei said, Zhao Zhongyao just wanted to explain. Tiantian rushed to say, 'Brother, you are so stupid, isn't it because the inside of this crater is very hot! Therefore, this crater is called a calorie crater. Because this crater is filled with calories. '

'Ha ha! Ha ha! Ha ha! ---'

After explaining this every day, Zhao Zhongyao, Feifei, and Qu Yuqian laughed together. After all, Tian Tian's explanation sounds very funny.

‘Tian Tian, ​​you explained so well, you have answered your brother’s question very well for me. Zhao Zhongyao looked at Tian Tian and said with a smile.

Zhao Zhongyao drove the spacecraft and took his family to fly a large circle in front of Mercury. They saw many impact craters and some mountains. The surface of Mercury is similar to that of the moon. But the composition of the two is completely different.

The moon is just a rocky planet, and there is basically no geological activity. The moon exists purely to control the speed of the earth's rotation.

Mercury is not the case. Mercury is an iron planet with a very high concentration. It is a planet composed of the core material of the planet. Mercury originally also had a shell. It's just this shell, and in an asteroid impact, only this asteroid was picked off. There is only such a core of Venus left.

Zhao Zhongyao took everyone to look at the front of Mercury, and everyone felt that there was nothing interesting. At this moment, Feifei looked at Zhao Zhongyao and asked, 'Dad, where do you think we should go to build amethyst gemstones. Didn't we come to Mercury just to find amethyst gems? '

After hearing what his son said, Zhao Zhongyao said, 'Of course, we are looking for amethyst gems. It's just that we now want to discuss where we should go to find amethyst gemstones. '

After hearing what Dad said, Feifei thought for a while and said, 'Dad, the amethyst gem we found on Venus is in an underground forest. Could there be such an underground forest on Mercury? '

After hearing Feifei's words, Zhao Zhongyao said,'This is hard to say, this is Mercury. Not Venus. What happens on Venus may not necessarily happen on Mercury. '

‘Dad, do you think there is life on Venus? If there is no life, does that mean that there will be no amethyst gemstones. ’ Feifei feels that amethyst gemstones seem to like being with living things. That's how it is on Venus, the amethyst gemstone, in an underground forest. And in this underground forest, there are many kinds of creatures.

‘You are right, if we want to find amethyst gemstones on Mercury, we can only find an oasis with life first. 'Zhao Zhongyao felt that what Feifei said made sense. If they want to find amethyst gems on Mercury, they must first find an oasis of life.

'Then where should we go to find the oasis of life? Is there an oasis of life on Mercury? ’ Feifei said again.

After hearing Feifei's words, Zhao Zhongyao thought about it again and said,'I feel that there must be an oasis of life on Mercury. If not, on the star map we saw, it would not appear that there is an amethyst gem on Mercury. Since the star map has already shown that there are some amethyst gemstones on Mercury, it means that there must be an oasis of life on Mercury. '

'Dad said that, and I also feel that since the star map has already told us that there is an amethyst gemstone on Mercury, then we should be able to find an oasis of life on Mercury. ’ After hearing what Dad said, Feifei said the same thing.

After hearing what his son said, Zhao Zhongyao nodded and said,'Yes, I think so too. It's just that we should now think about where the oasis of life on Mercury might be. We are on Venus, although we saw an oasis of life. But at that time, we discovered that piece of underground forest by accident. But when we come to Mercury, can we still see an oasis of life by accident? '

After hearing what Dad said, Feifei said again, 'Dad, then you said we should go there to find the oasis of life. There seems to be no oasis of life on the front of Mercury! Is that the oasis of life on Mercury? It should be on the back of Mercury. '

Feifei also feels that the temperature on the front of Mercury is very high, with an average temperature of more than 400 degrees. In such an environment, it is impossible for life to exist. The backside of Mercury is different. Although the temperature on the back is very low. However, in some special terrains, there may be a relatively warm and humid place that can support life.

Zhao Zhongyao thought for a while and said, ‘If Mercury has life, it should be on the back of Mercury. The front is unlikely to be alive. We should go to the back side of Mercury to find it now. '

Well, let's go to the back of Mercury and look for it. ’ After hearing what Dad said, Feifei said this again.

'Okay, then let's go to the back of Mercury and try to find it. After Zhao Zhongyao finished speaking, he drove the spaceship to the back of Mercury.

To say that on the front of Mercury, everyone can see the topography and landforms on the surface of Mercury below. But it's different on the back side of Mercury. The back of Mercury is pitch black and nothing can be seen. It is also very difficult to find life on the back of Mercury.

However, Zhao Zhongyao and the others also had lighting equipment on the spacecraft. Even in the dark, searchlights can be used to provide illumination. Of course, even if it can be illuminated with searchlights, it cannot fly too high.

If you fly too high, the searchlights on the spacecraft are useless. After all, Mercury is a huge planet. A spaceship flying in the dark night above a planet is just like a firefly flying in the dark. Although the light of the searchlight on the spacecraft is also very bright. But it can only irradiate a few hundred square meters on the ground. If it is farther away, it will not be clear.

Zhao Zhongyao flew the spaceship in the dark night background of Mercury. He was flying the spaceship at an altitude of one kilometer above the ground. Because only at this height can the situation on the ground be observed to the maximum extent. If you see an oasis of life, you can find it very quickly.

But Mercury is huge. A spaceship is compared to a planet. No matter how big the spaceship is, it looks very small in front of a planet. Although the spaceship that Zhao Zhongyao was driving was a large spaceship, it was obviously extremely small on the back of Mercury.

Zhao Zhongyao drove the spacecraft on the back of Mercury for half a day, but still found no sign of an oasis of life.

The back of Mercury, though in darkness. But under the illumination of the searchlights of the spacecraft, everyone can see that the back of Mercury is similar to the front, and they are all large and small impact craters. Apart from these things, there seems to be nothing special.
