Chapter 1714: Big Reservoir Dirty Snowball

The first thousand eight hundred and eighty-eight chapters of the big reservoir dirty snowball
Feifei heard what Dad said, and said, ‘Okay! I want to see if this small Oort Cloud celestial body is different from other small celestial bodies. Is there anything special about the small celestial bodies here! ’
At this time, Tiantian looked at the weird little celestial body that was constantly approaching the spacecraft in the distance and said, ‘Dad, what kind of little celestial body is this, how dirty it looks! ’
Zhao Zhongyao laughed after hearing his daughter's words, and said, ‘This kind of small celestial bodies are the most common small celestial bodies in the Oort Cloud. Our academic circles generally like to call them dirty snowballs. In fact, it is what we call a comet. ’
After hearing what my father said, Feifei smiled and said, ‘haha, this is really a vivid title! If you say so, there are countless dirty snowballs in this Oort Cloud. ’
‘Of course, the entire Oort Cloud is a huge reservoir, and this reservoir is formed by the accumulation of countless dirty earths. Said Zhao Zhongyao.
‘Dad, what use are these so many dirty snowballs in this place! It doesn't seem to have much to do with our earth! Feifei asked another question casually.
After hearing Feifei’s words, Zhao Zhongyao smiled and said, ‘Don’t say that. The dirty snowballs here are very important to our planet. ’
‘Why, our earth is so far away from this Oort Cloud, how can everything here have anything to do with our earth. Feifei was still a little puzzled after hearing what his father said.
‘That’s right, now our scientists concerned have come to a very well-founded conclusion. All the water resources on our earth 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 recent studies, all the water resources on our planet may come from the Oort Cloud, this huge reservoir. ’
After hearing what my father said, Feifei asked in surprise,'Dad, what do you say, the water on our earth is transported from here, then who is it that transported the water from here to our earth? NS. ’
At this moment, Zhao Zhongyao smiled and said, ‘No one can transport water from the Oort Cloud to our place on Earth. All the water on our earth passed by itself from the place of Oort Cloud. ’
‘What, the water will run over by itself, isn’t it amazing! After hearing what my father said, Feifei couldn't believe it at all. How could something like this really happen!
'Yes! Dad, how could this Oort Cloud water fly to our earth by itself! Hearing what my father said every day, he naturally looked puzzled.
‘Why not, the entire Oort Cloud, although on the surface it has nothing to do with our planet, but it actually 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 do not stay here freely. They are all affected by the sun's gravity and revolve around the sun all the time.
Because this place is far away from the sun, every dirty snowball takes a long time to revolve around the sun. If the trajectory of the dirty snowballs here does not change, they may continue to operate here.
However, some dirty snowballs may be hit by other dirty snowballs and then change their orbits. Some of them may deviate from the previous orbit and enter the inner region of the sun from the outer solar system.
These dirty snowballs that enter the inner region of the sun are what we people on earth 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 land on the earth. Then it melts on the surface of the earth and becomes the first water resource on the earth.
Billions of years ago, the earth must have suffered a large number of meteor shower events. This time the meteor shower event caused a lot of water to appear on the earth.
The existence of water on the earth laid the foundation for the emergence of life. If there hadn't been this serious meteor shower event, there would have been so much water on the earth, and it would have been impossible to give birth to life.
Therefore, life on Earth has a lot to do with the dirty snowballs in the Oort Cloud. Now we can't feel these dirty snowballs. Not only are they unsightly, they are 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. After listening to Feifei and Tiantian, they both felt very magical.
‘Dad, so to speak, life on earth has a very close relationship with this Oort Cloud! Said Feifei.
‘Of course, without this Oort Cloud, perhaps there would be no life on Earth. Said Zhao Zhongyao.
‘Dad, how did this Oort Cloud come into being! How could there be such an Oort cloud in the periphery of our solar system! Feifei is becoming more and more curious about this Oort Cloud.
After hearing what Feifei said, 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 not a cloud! Feifei was still a little puzzled after hearing what his father said.
‘It’s like this. Although we say that the Oort Cloud is something like a cloud, it is definitely not the same thing as the cloud on our planet. The Oort Cloud is an aggregate of small celestial bodies that surrounds the entire periphery of 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 and asked.
‘Of course it does matter. Five billion years ago, the solar system didn’t exist, it was just a molecular cloud. This molecular cloud may be a relic left by the death of an earlier giant star.
It is this relic that is constantly rotating and changing under the action of gravity. There is more and more accumulated matter in the middle part, the internal pressure is getting bigger and the temperature is getting higher and higher, finally reaching the level of nuclear fusion, and a brand-new star is born.
