The first thousand five hundred and forty chapters white mist

Soon the flying saucer spacecraft descended to a depth of one kilometer. They are now in the center of the enclosed space of the entire Shackleton Crater.

When they arrived at this place, Zhao Zhongyao felt that there should be no problems with their environment. After all, it has fallen two kilometers. Nothing dangerous was found at all.

‘Okay, it seems there is nothing dangerous in this, we can go down a bit faster. Zhao Zhongyao speeded up as he spoke.

But as soon as he descended about a hundred meters, he saw that outside the flying saucer, in the empty space, something like mist suddenly appeared. These things should have been very calm. But now it seemed to be hit by a flying saucer, and then it started tossing around.

When Zhao Zhongyao saw the white mist, Feifei, Tiantian and Qu Yuqian also saw the white mist.

Feifei looked at her dad in a puzzled way and asked, ‘Dad, what is this mist. How does it look like fog on our earth! ’

After hearing Feifei's words, Zhao Zhongyao also looked at the fog near the flying saucer. He was also very surprised and didn't know what these white fog was.

‘I don’t know, these things should not be fog. Because there is no air and no water on the moon, how can there be fog. "Zhao Zhongyao also didn't understand what these white misty things were. But he felt that these things shouldn't be mist.

‘Dad, are these mists just some ice material? When Feifei saw the mist, he thought of a special celestial body in the solar system-a comet.

Comets are indeed very unique objects in the solar system. These celestial bodies are actually made of ice material. When they fly close to the sun, they will volatilize, and then turn the whole body into a big broom. This is really a very magical thing. Therefore, the ancients in our country called the comet the broom star.

The ancients in our country were also very clever in knowing this type of comet. They not only said vividly that this kind of comet with a long tail is called broom star, but also believed that unfortunate things would happen when such broom star passed through the sky. Therefore, this broom star is an unlucky star.

The reason why the ancients called a comet a broom star is also very reasonable. Because when a comet flies near the sun, it does cause some serious consequences. Because this asteroid will become an asteroid with a long tail after it volatilizes. Its tail is very long. Generally speaking, comets with smaller masses have shorter tails. A comet with a larger mass will have a longer tail. But even for a comet with a small mass, its tail is millions of kilometers long. If there are some very high masses of Huitail, its tail may be hundreds of millions of kilometers, or even a billion kilometers long.

If the long tail of a comet is very long, it may affect the earth's environment when it passes through the earth's orbit. When the comet's giant wit tail sweeps over the earth, it will cause the earth to suffer a meteor shower.

If these meteor showers are just some ice material with a small mass, they may not cause any harm to the earth. Because these low-mass ice materials will rub against the atmosphere when they fly over the earth, and then they will disappear into a meteor. In this way, not only will they not cause us any harm, on the contrary, they will also create a spectacular meteor shower for us to watch.

However, if some of these ice materials are relatively large and fall on the earth before they are burnt down when flying through the atmosphere, it will not be so fun. If the mass of ice material falling on the earth is large enough, the consequences will be very serious.

It is said that the asteroid that hit the earth 65 million years ago and caused the extinction of the dinosaurs was a small comet. This small comet, it is very likely that a large comet passed near the sun and was disintegrated by the high temperature of the sun, and it became many comets. These comets are flying above the solar system's low earth orbit. A comet with a relatively large mass accidentally flew to the vicinity of the earth, was captured by the gravity of the earth, and then hit the earth. Caused a serious extinction of dinosaurs.

To say that we modern people know that when comets pass by, they may have a serious impact on the earth. However, how the ancients knew that when a comet passed by, it would have a serious impact on the earth, which is unknown.

But the ancients knew that when a comet passed by, some serious natural disasters might happen. It is precisely because of this that they call the comet a broom star, and feel that when the comet passes over the earth, it is an unlucky phenomenon.

Feifei also knows a little about comets. When he looked at the ice material in front of him, he also thought of comets, special celestial bodies in the sun.

When Zhao Zhongyao heard Feifei say this, he felt that it made sense. After all, if the things in the anti-impact crater were not the ice material of the comet, it would not be anything else. Because only the ice material of the comet can form this kind of thing like mist.

In fact, the ice material in the comet is similar to the ice material on the earth, and of course it is not the same. According to observations by modern scientists, the composition of the ice material on the comet is very similar to the composition of the earth's sea water. This further proves that the water on the earth is probably the result of many comets hitting the earth.

For example, the past science told people such a story-comets are the source of water on the earth. In the eternal age 3.8 billion years ago, the primitive earth was still a hot and dense fireball. It was a purgatory where life could not exist. However, countless comets traveled across the sky and visited the earth for thousands of miles. These ice crystals of the universe are integrated into the earth under the guidance of gravity, and inject sufficient water into the earth, thus writing the necessary preface for the opening of the chapter of life.

The story is wonderful, but more clues discovered by scientists indicate that things are far from simple. Is the comet the source of the water of the earth? Or is this a beautiful misunderstanding after all? How many possible sources are there for water on earth? This matter seems to need to be discussed carefully.

Some modern scientists believe that the water on the earth was formed by volcanic eruptions in the early earth. It is the combination of some hydrogen and oxygen produced by a volcanic eruption, which forms rainwater, which falls on the ground and forms the ocean.

However, when people studied the isotope of this so-called volcanic "primary water", they unexpectedly discovered that they are composed of isotopes very similar to surface water, which proves that they actually only seep into the ground and then regenerate. Ground water circulating to the surface. Research on celestial geology that has emerged in modern times has shown that among the Earth’s close neighbors, Venus and Mercury, which are closer to the sun, Mars, which is further away from the sun, or even the nearest moon to the earth, are poor in water. Only the earth is unique. Having such a huge amount of water, this cannot but make people feel strange. Scientists have different ideas about this.

Some people believe that the water on the earth, at least most of the water, is not inherent to the earth, but is brought by a comet that crashed into the earth. Recently, some scientists at the University of Iowa in the United States have found that there are always small black spots on the disc-shaped image of the earth in thousands of ultraviolet radiation photos of the Earth’s atmosphere sent back from artificial satellites. Each small black spot exists for about two to three minutes, covering an area of ​​about 2,000 square kilometers. After careful inspection and analysis, they believe that these spots are caused by some small comets made of ice that rush into the earth’s atmosphere. This meteoric ice is caused by friction. The result of heat generation into water vapor.

From the photos, it can be estimated that about 20 such small comets enter the earth every minute. If its average diameter is 10 meters, 1,000 cubic meters of water enter the earth every minute, which can reach about 0.5 cubic kilometers in a year. Based on this, it can be inferred that in the 4.6 billion years since the formation of the earth, 2.3 billion cubic kilometers of comet water will enter the earth. This figure obviously greatly exceeds the total amount of seawater available. Therefore, whether the opinions of the scientists at the University of Iowa are reliable remains to be verified.

So, in any case, where the water on the earth comes from is an unsolved mystery. Although many of our modern scientists want to solve this puzzle. But nature seems to like to tease humans. No matter how many methods humans use, it is difficult to explain where the water on earth comes from.

Now Zhao Zhongyao and their wives and children are on the moon. The moon is not only a satellite of the earth, but also a history museum. In this ‘history museum’, there may be some evidence about where the water on the earth came from.

What Zhao Zhongyao and the others saw from high above was only the appearance of the entire impact crater. I feel that the impact crater is not too big. But when they really flew to the top of a mountain in the impact crater, they felt that the impact crater was also very large. After all, this impact crater is also more than 20 kilometers wide and four to five kilometers deep.

Zhao Zhongyao now came to this Shackleton crater with his wife and children. They have descended to a depth of two kilometers in this place. Zhao Zhongyao and they saw some strange things.

These things are some mist-like gases. As soon as he saw the gas, Feifei wondered if it was some comet ice material.

Zhao Zhongyao heard Feifei’s words and said, ‘what you said makes sense, but we still have to go to the bottom of the impact crater. Maybe there is the answer we want to know. ’

‘Okay, let’s go down now! Feifei is becoming more and more curious.

Therefore, Zhao Zhongyao wanted to speed up to the bottom of the impact crater. But when he started to accelerate again, the spacecraft suddenly shook. It was as if something was pushing the spaceship.

This time, Zhao Zhongyao was frightened. Not only Zhao Zhongyao, but of course his wife and children. They were all terrified.

‘Dad, what is going on, why is our spaceship shaking. Feifei asked Zhao Zhongyao with a surprised look.

Tian Tian and Qu Yuqian were the same. When they felt the whole spaceship was shaking, Huarong was shocked. After all, this is the first danger they have encountered since their expedition to the moon.

Originally, the moon was already a familiar place for Zhao Zhongyao and others. After all, Zhao Zhongyao and the others have already built a moon city on the moon. There are already people living here on the moon.

But the moon is also very big. Compared with the entire moon, the Moon City is really negligible. Even now there are 100,000 people living in the Moon City. But people like them can only live in the moon city. Normally it is impossible to leave the moon city by one step. If they want to leave the moon city, they have to take a flying saucer spacecraft to leave, otherwise, it is impossible for them to leave the moon city one step.

Although these people live on the moon, they certainly don't understand the moon. Don't talk about them. Even Zhao Zhongyao, the chief designer of the moon city, often comes to the moon and has studied a lot of information about the moon. Even so, Zhao Zhongyao knew that he still knew very little about the moon. After all, the moon is also very large, and it is not easy to understand the moon comprehensively.

In fact, let alone the moon, we know much about the earth. Although we humans have lived on the earth for millions of years. But the days when we really look at our earth from a scientific perspective are not far away. It is difficult for our ancients to look at the earth on which we live from the perspective of modern science.

Therefore, the moon still has high research value for us humans. If we want to understand the earth, we can also start from understanding the moon. After all, the moon may have higher research value than the earth.

This is because the environment on the earth, due to natural and man-made reasons, is now very different from hundreds of millions of years ago. If we want to understand the earth hundreds of millions of years ago, it is difficult to find any evidence.

But the moon is different. The moon is a ‘historical museum’ of the solar system. In this ‘history museum’, there are many things that can serve as evidence for our research on the origin of humans and the origin of life on earth.

Among us, there is no life on the moon, only some craters, and we feel that there is no research value on the moon. If we think this way, we are quite wrong. It is precisely because there is no life on the moon that it will become more precious and indispensable to us humans. Because of the moon, we can understand our earth better.
