Chapter 1705: Flying to the Oort Cloud

The first thousand eight hundred and ninety-nine chapters fly to the Oort Cloud
After hearing what my father said, Feifei smiled and said, ‘Okay, let’s go to the edge of the solar system and take a look! I'm really curious now, and I don't know what the edge of the solar system is like. ’
I didn’t speak for a long time, and at this time I looked at Zhao Zhongyao curiously and asked, ‘Dad, what do you think the edge of the solar system looks like, can you describe it to us first? ’
After hearing what Tiantian said, Zhao Zhongyao said, ‘I don’t know much about this knowledge, but I still know a little bit. Now I will tell you what the edge of the solar system looks like! ’
After that, Zhao Zhongyao thought for a while and said, ‘According to the research of some scientists, it is shown that at the edge of our solar system, there is an extremely large Oort cloud composed of countless ice and snow balls. ’
When Feifei and Tiantian heard Zhao Zhongyao talk about the ‘Olt’ cloud, they were a little puzzled, and they didn’t understand what Zhao Zhongyao said about the ‘Olt’ cloud.
‘Dad, what exactly is this Oort Cloud you are talking about? Feifei was a little puzzled, looked at Zhao Zhongyao and asked.
‘Yes, dad, first explain to us what this Oort Cloud is about! He looked at Zhao Zhongyao and asked every day.
At this time, Zhao Zhongyao looked at the two children again and said, ‘This Oort Cloud is a very huge comet home made up of countless comets. Here is the edge of the solar system.
Our entire solar system is actually a very special star system surrounded by a very huge Oort cloud.
It is precisely because our solar system has a huge Oort cloud that makes all the planets in our solar system operate very safely.
It can be said that human beings on Earth also benefit from this Oort cloud. If it weren’t for the Oort cloud to protect the safety of the earth and some other large planets, the entire solar system would suffer from it at any time. Attack of the wandering planet. ’
When Zhao Zhongyao said this, he stopped for a while, wanting to see Feifei and Tiantian, if there is anything else to ask.
At this time, Feifei asked in a puzzled manner, ‘Dad, what is the wandering planet you are talking about? I seem to have heard this term for the first time. ’
After hearing Feifei’s words, Zhao Zhongyao explained, ‘Wandering planets are planets that leave the parent star and fly freely inside the galaxy. ’
‘Oh, how could this happen, how could these planets leave their parent stars! Feifei is still a little puzzled.
‘This is because, in a galaxy, there are many stars that do not live as long as the sun’s tens of billions of years. Many stars, due to their large size, the hydrogen element in them burns quickly, and their life spans are also very short. Generally speaking, the lifespan of these large stars with masses several times that of the sun is only a few hundred million years, or tens of millions of years.
Although hundreds of millions of years or tens of millions of years, compared to the life span of human beings, it is very long. But relative to the sun, it is very short-lived.
These short-lived stars will also form some planets around them. However, when these stars ‘dead’, the planets around them may be directly ‘swallowed’ by their parent stars. Of course, it is also possible to lose the gravitational force of the parent star, and then wander around in the galaxy.
Generally speaking, those planets that are relatively close to the parent star will cause the parent star to burst and be destroyed directly. However, those planets that are far away from the parent star may directly cause the parent star to explode, and the gravitational wave generated by the parent star may be directly pushed into the interstellar space.
These planets that are pushed into interstellar space by the powerful gravitational waves of their parent stars will eventually become wandering planets. They will continue to wander inside the galaxy until they are captured by another star.
Some of these large planets and moons near our solar system may have wandered from interstellar space to the vicinity of the solar system, and then were captured by the sun.
Even the nearest moon to our earth may be a wandering planet. It may also have flown from far away in the interstellar space to the vicinity of the solar system billions of years ago, and then captured the strong gravitational force of the sun.
The moon may be a planet at the beginning, but because its orbit is relatively close to the earth, in an accidental close contact, the earth was captured, and then it became a satellite of the earth.
Of course, this is just a hypothesis, exactly how the moon came into being. There is no unified theory in the world. Although there are various hypotheses, none of them can perfectly explain the existence of the moon.
In any case, the solar system is relatively safe and stable. Because in its fringe, there is a circle of solar system ‘shell’ made up of ice and snow comets. It is precisely because the solar system has this ‘shell’. So that when the solar system travels through the Milky Way, it will not be attacked by some stars from interstellar space.
Life on our planet is also protected by the Oort Cloud, so that it can survive indefinitely. ’
Zhao Zhongyao looked at Feifei and Tiantian, and said what he knew, some knowledge about Oort Cloud.
After Zhao Zhongyao said this, Feifei and Tiantian had a general understanding of this ‘Olt’ cloud.
‘Dad, so to speak, this Oort Cloud is a very magical celestial body. Feifei looked at Zhao Zhongyao and said.
'Yes! Hearing what my father said, I want to go to Oortyun immediately. ’Said the same every day.
‘Okay, let’s start flying to the Oort Cloud right away! After hearing the words of the two children, Zhao Zhongyao piloted the spacecraft again and flew towards the very distant Oort Cloud.
It's just that when the spacecraft starts to fly from the inner space of the solar system to the outer space, it makes people feel that the outer space and inner space of the solar system are very different.
In the inner space of the solar system, some relatively large celestial bodies can be seen to some extent. But when the spacecraft flew into the outer space of the solar system, it felt like there was nothing, nothing, and it felt like it had flown into interstellar space.
Feifei watched the spaceship flying for a long time, and there was nothing, so she said strangely, ‘Dad, there are no celestial bodies in the space here! Could it be that we have already flown into the outer space of the solar system. ’
At this time, Zhao Zhongyao looked at the display in the cockpit of the spacecraft and said, ‘We have not yet flown to the outer space of the solar system, we are still in the inner space of the solar system. ’
‘Dad, how can the space here be empty! Whatever happened, we should also see some celestial bodies! Feifei said again in a puzzled manner.
