Chapter 1888: Big Reservoir Dirty Snowball

After hearing what his father said, Feifei also said, 'Okay! I want to see if this small Oort cloud object is different from other small objects. Is there anything special about the small celestial bodies here? '

At this time, Tiantian also looked at the weird little celestial body approaching the spaceship in the distance and said, 'Dad, what kind of little celestial body is this, why does it look so dirty! '

After hearing what his daughter said, Zhao Zhongyao smiled and said, "This kind of small celestial body is the most common small celestial body in the Oort cloud. In our academic circles, we generally like to call them dirty snowballs." In fact, it is what we call a comet. '

After hearing what his father said, Feifei also smiled and said, "Haha, this is really a vivid name!" If so, there are countless dirty snowballs in this Oort cloud. '

‘Of course, the entire Oort cloud is an extremely huge large reservoir, and this large reservoir is formed by the accumulation of countless dirty earth. Zhao Zhongyao said so.

'Dad, what use are there to be so many dirty snowballs in this place! It seems that it has nothing to do with our earth! ’ Feifei casually asked another question.

After hearing Feifei's words, Zhao Zhongyao smiled and said,'Don't say that, the dirty snowball here is very important to our earth. '

‘Why, our earth is so far away from this Oort cloud, how can everything here have anything to do with our earth. ’ After hearing what Dad said, Feifei was still a little puzzled.

'That's right, now our relevant scientists have come to a well-founded conclusion. All the water resources on our planet come from outside the earth. But if the water on the earth is not produced by itself, where can it come from! 'Zhao Zhongyao said a few words like this first.

After a pause, Zhao Zhongyao looked at everyone again and said, ‘According to some latest research, all the water resources on our earth may come from the Oort cloud, this huge reservoir. '

After hearing what his father said, Feifei was very surprised and asked, "Dad, what are you talking about, the water on our earth is transported from here, so who the hell transported the water from here to our earth?" up. '

At this time, Zhao Zhongyao smiled and said, 'No one can transport water from the Oort cloud to our earth. All the water on our planet passed by itself from the Oort cloud. '

'What, the water will run over by itself, isn't it amazing! ’ Feifei couldn’t believe what his father said, and felt that such a thing could really happen!

'yes! Dad, how could the water in the Oort cloud fly to our earth by itself! ’ Hearing Dad’s words every day, he naturally had a puzzled expression on his face.

‘Why not, the entire Oort cloud, although on the surface, it doesn’t have much to do with our earth, but in fact it has a lot to do with it. Especially this Oort cloud has a very close relationship with the sun.

Although there are countless dirty snowballs in the entire Oort cloud, they don't stay here freely. They are all affected by the sun's gravity and revolve around the sun all the time.

Since this place is relatively far from the sun, it takes a very long time for each dirty snowball to revolve around the sun. If the orbit of the dirty snowballs here doesn't change, they may always be here.

However, some dirty snowballs may be hit by other dirty snowballs, and then change their orbits. Some of them may break away from their previous orbits and enter the inner region of the sun from the outer reaches of the solar system.

These dirty snowballs that enter the inner region of the sun are what we earthlings call comets. If these comets are relatively close to the earth, they may be captured by the earth.

In this way, these dirty snowballs will fall to the earth. Then it melts on the surface of the earth and becomes the first water resource on the earth.

Billions of years ago, Earth must have suffered a massive meteor shower event. This meteor shower event caused a lot of water to appear on the earth.

The existence of water on the earth also laid the foundation for the emergence of life. If there hadn't been this serious meteor shower event, then there would not be so much water on the earth, and it would be impossible to breed life.

Therefore, the life on the earth has a lot to do with the dirty snowballs in the Oort cloud. Now we can't feel that these dirty snowballs are not only ugly, but also very common. In fact, they are not ordinary at all, they are very magical things. '

Looking at his son and daughter, Zhao Zhongyao talked about the origin of life on earth. It made Feifei and Tiantian feel very magical after listening to it.

‘Dad, so the life on earth is closely related to this Oort cloud! ’ Said Feifei.

‘Of course, without this Oort cloud, maybe there would be no life on Earth. Zhao Zhongyao said so.

‘Dad, how did this Oort cloud form! How could there be such an Oort cloud in the outskirts of our solar system! ’ Feifei became more and more curious about the Oort cloud.

After hearing Feifei's words, Zhao Zhongyao smiled and said, 'Actually, to be precise, this Oort cloud is not a cloud, but a circle of clouds. '

‘Oh, it’s a circle of clouds, why isn’t it a cloud! ’ After hearing what Dad said, Feifei was still a little puzzled.

'Well, although we say that the Oort Cloud is a cloud-like thing, it is definitely not

The same thing as clouds on our planet. The Oort cloud is a collection of small celestial bodies that surrounds the Sun. Inside, there are countless comets, and some other small celestial bodies. Zhao Zhongyao said again.

‘Dad, how did this circle of small celestial bodies form? Does it have anything to do with the formation of the solar system! Feifei looked at Zhao Zhongyao again and asked.

‘Of course it does. Five billion years ago, the solar system didn’t exist, it was just a molecular cloud. This molecular cloud may be a remnant of an earlier, massive star that died.

It is this piece of ruins that is constantly rotating and changing under the action of gravity. The middle part accumulates more and more matter, the internal pressure increases and the temperature increases, and finally reaches the level of nuclear fusion, and a brand new star is produced in this way.
