Chapter 1499: Xinghui Yueying

The first thousand five hundred and thirty-four chapters
Feifei looked at the crater in front of him, and felt that it was not much different from the Kepler crater he had seen before. He also felt that this crater was nothing beautiful, wouldn't it be an ordinary crater? !
‘Dad, this crater is nothing beautiful, isn’t it just an ordinary crater! At this moment, Feifei looked at Zhao Zhongyao again and said.
After hearing Feifei’s words, Zhao Zhongyao said again, ‘Feifei, don’t you think this crater is similar to Kepler. But this crater is indeed very different from the Kepler crater. ’
‘Oh, what’s the difference, aren’t they all craters? Feifei said very puzzled after hearing what his father said.
‘First of all, the time of their formation is very different. Kepler crater may have formed hundreds of millions of years ago. The Tycho crater may have a history of tens of millions of years. On the moon, any crater may be a product of hundreds of millions of years, or even billions of years.
But Tycho crater is different, it is a very young crater. From this point of view, Tycho crater and Kepler crater are very different. Zhao Zhongyao looked at Feifei again and said.
Upon hearing this, Feifei asked incomprehensibly, ‘dad, this Tycho crater is much younger than the Kaiping crater. What are the characteristics of this young crater? ’
After hearing what his son said, Zhao Zhongyao said, ‘the young Tycho crater this year is probably related to the extinction of our planet’s dinosaurs 65 million years ago. ’
'what! Related to the dinosaur extinction event! When Feifei heard Zhao Zhongyao say this, he felt very strange. After all, he couldn't think of any relationship between this crater and the extinction of dinosaurs on Earth.
‘Yes, it’s related to the extinction of dinosaurs on Earth. Zhao Zhongyao looked at Feifei and said.
‘Dad, hurry up and talk about it. I really want to know what is going on. Feifei looked at his father very curiously and said.
‘Ok, then I’ll tell a story about this Tycho crater. Zhao Zhongyao looked at Feifei again and said.
Tiantian and Qu Yuqian listened to the dialogue between Zhao Zhongyao and Feifei. The two of them were also very curious, so they sat around Zhao Zhongyao together, wanting to hear Zhao Zhongyao tell a story about this Tycho crater.
‘65 million years ago, there was a relatively large asteroid in the asteroid belt between Mars and Jupiter. The diameter may be one hundred and forty kilometers. But during its operation, this huge asteroid collided with another larger asteroid for some reason.
This asteroid, one hundred and forty kilometers in diameter, was knocked apart by another asteroid. This asteroid split into many asteroids. The two asteroids that hit the moon and the earth were split from this asteroid with a diameter of 140 kilometers.
In fact, the asteroid that hit the earth created the asteroid in the famous dinosaur extinction event, and was the prime culprit of the dinosaur extinction event on the earth. At that time, this asteroid with a diameter of ten kilometers, after it hit the earth, the energy it produced was unimaginable.
According to calculations by relevant scientists, the energy produced by the asteroid that hit the earth at that time was almost equivalent to one trillion tons of TNT equivalent. And the explosive equivalent of the most powerful hydrogen bomb ever manufactured by mankind is only 50 million tons of TNT equivalent. In contrast, the energy produced by the hydrogen bomb produced by humans is not worth mentioning at all.
The crater formed by the impact of this asteroid at that time still exists today. This crater is the famous Chicxulub crater.
The Chicxulub crater is a crater impact remnant found in Yucatan, Mexico, or Yucatan. It was once the largest crater on the earth (the largest crater currently found is made on millions of years of thick ice The largest crater ever found under the bed: Wilkes Land crater, this 483 kilometers wide crater is 250 million years old.); Chicxulub is a village on it. The crater body is not visible on the surface. It is estimated that the crater is slightly elliptical overall, with an average diameter of about 180 kilometers; the meteorite that caused the crater, estimated to be about 10 kilometers in diameter, completely evaporated after impact and released up to 5.0×10^23 joules of energy, equivalent to More than 90 trillion tons of TNT explosives are enough to cause tsunamis, earthquakes and volcanic eruptions, and cause a large amount of dust to enter the atmosphere, completely cover the sun, change the global climate, and cause a nuclear winter.
It can be said that this asteroid with a diameter of ten kilometers has had a great impact on life on the earth and directly led to the extinction of the dinosaur species that has dominated the earth for nearly 200 million years.
Although this impact event has had a huge impact on life activities on Earth. But sometimes, bad things can turn into good things. Although this impact event objectively caused great harm to the species on the earth. But it also promoted the development of mammals.
Because before this asteroid impact. The life forms on earth are almost dominated by reptiles dominated by dinosaurs. However, since the discovery of the impact event, the ecology of the entire planet has undergone wonderful changes.
The reptiles that originally ruled the earth withdrew from the stage of history. Mammals that have been struggling to survive have been on the stage of history. It was precisely because of the development of mammals that the foundation for the subsequent emergence of humans was laid.
It is no exaggeration to say, if it weren't for this asteroid impact. If dinosaurs, such as reptiles that have dominated the earth for nearly 200 million years, are not extinct, there will be no subsequent development of mammals and the emergence of humans.
And if the moon hadn't stopped another asteroid, the consequences might not be what it is now. Because these two asteroids were very large at that time. The diameter has reached ten kilometers. When such a large asteroid hits the earth, it will cause serious damage to the ecological environment of the earth.
If these two asteroids with a diameter of about ten kilometers all hit the earth. The consequence may not only be extinction of reptiles, mainly dinosaurs. It is very possible that even the mammals that survived in the cracks have also become extinct.
If that were the case, it might be difficult for life on earth to develop. Even if it will all be extinct. But if you want to continue to evolve, it may be more troublesome. It may take hundreds of millions of years to slowly develop.
But what makes people feel incredible is that the moon just stopped this asteroid at that time. Let another asteroid hit the earth. It is the prosperous scene of human beings on earth today.
Everything seems to have been predestined. Perhaps all of this was arranged long ago. Everything is independent of human will.
If there happened to be an asteroid hitting the earth at that time, then there would be no prosperity for humans on the earth. If both asteroids hit the moon and the moon is blocked, then the earth may still be in an era when dinosaurs are rampant, and there will be no mammalian development, and no human civilization will be born. Up.
From this extinction event of the dinosaurs, we once again saw the role of the moon on our earth. The moon is not only a satellite, but also a planet that breeds life together with the earth. ’
Zhao Zhongyao looked at Feifei, Tiantian and Qu Yuqian and said about this Tygu crater. After the whole family listened, they also thought it was very interesting and also felt very magical.
However, at this moment, Feifei thought of another question. It is the naming problem of this Tycho crater. This crater is the Tycho crater. The name seems to be unknown to most people. Unlike Kepler Crater, it is the name of a more famous astronomer. And who is Tycho and how could he use his name to name this crater!
Thinking of this, Feifei looked at Zhao Zhongyao and said, ‘Dad, I already know the story of Tycho Crater. It's just that the name of this Tycho crater is still not familiar to me. This Tycho crater should be named after Tycho. But I don’t know who this Tycho is, and why is this crater named after him! This Tycho doesn't seem to be famous! Why not use a more famous astronomer to name it? ’
After hearing Feifei’s words, Zhao Zhongyao thought for a while and said, ‘you don’t know Tycho, it doesn’t mean that he is not famous. In fact, Tycho is also a very famous astronomer. ’
Feifei heard what Dad said, and said puzzledly, ‘Is he famous! How could he be famous for Kepler. Why don't you name this important crater after Kepler? ’
After hearing what his son said, Zhao Zhongyao smiled and said, ‘son, it seems that you don’t know much about Tycho. You don’t know much about the relationship between Tycho and Kepler. If you understand the relationship between Tycho and Kepler, you might not ask like that. ’
Feifei said in a puzzled manner after hearing what his father said, ‘dad, what is the relationship between Tycho and Kepler, can you tell me something. ’
‘Okay, then I will tell you something about this Kepler and Tycho! After Zhao Zhongyao finished speaking, he thought for a while. He wanted to recall what he knew about Kepler and Tycho.
Zhao Zhongyao thought for a while and then began to talk. Feifei, Tiantian and Qu Yuqian all came to Zhao Zhongyao again, surrounded him quietly, listening to him tell stories about Tycho Brahe and Johannes Kepler.
‘At the beginning of the sixteenth century AD, in Denmark, a man of noble origin, Tycho Brahe, had longed for the mysterious sky since he was a child, determined to become a famous astrologer. In order to be able to guess the mystery of the stars accurately, he worked tirelessly to make a large number of observations and records of the celestial bodies, and gradually entered the orbit of scientific research.
He received strong support from the Danish emperor. Was hired as a queen mathematician. And he could use the most advanced observatory at that time, so that he had enviable working conditions, and he himself was respected like stars holding the moon.
The position of the 777 stars he measured had an error of almost 4 arc minutes before a telescope, creating an unprecedented miracle! He discovered a super-bright nova, named "Tycho Nova". The name of the new star comes from its discoverer-Tycho.
Tycho is recognized as the founder of modern measured astronomy.
Tycho’s success lies not only in observing and recording a large number of celestial body data, but also in his discovery of a special astronomer, Kepler, and passing the baton of astronomy research to him.
Kepler, who was born in a German aristocratic family, never enjoyed the glory and luxury of aristocracy. On the contrary, his life has been associated with disease and poverty. Fighting stubbornly against social pressure and family misfortune, he turned from a theological admirer to a materialistic astronomer.
However, when Tycho became famous in Europe, Kepler was just emerging. Although they admire each other very much, for various reasons, they missed each other.
February 3, 1600. It is a memorable day in the history of astronomy. After a difficult journey, Kepler was finally invited to Prague, where Tycho worked.
Tycho is characterized by sharp eyesight. Strong body, luxurious life, grumpy, and authoritative. He is good at precise observation, but lacks imagination and does not believe in Copernicus's theory.
Kepler's eyes are nearsighted. He is weak and kind to others, but he is strong-willed and imaginative. Especially his mathematical analysis ability was unmatched at that time, and he believed in the rationality of Copernicus's theory.
However, the common career and goals have brought these two people with diametrically opposite personalities and abilities to each other closely together. Tycho appreciates Kepler's wisdom, and Kepler respects Tycho's diligence and reputation. They two hit it off and became good friends.
When the two "new stars" wandering in the sky met, a new page was opened in the history of modern astronomy. According to a large amount of information obtained by Tycho, Kepler has analyzed and reasoned. Summarized the three laws of planetary motion, Kepler was also known as the "legislator of the sky."
Without Tycho's accumulation of data for decades, it would be difficult for Kepler to achieve such a glorious achievement: Without Kepler's analysis and reasoning, Tycho's observational data would not know how many years would remain dormant. The cooperation between the two of them is really a perfect match.
It's a pity that their time together is very short. In less than a year, Tycho bid farewell to the world. But their friendship lasts forever. Kepler has not forgotten Tycho's dying entrustment, and has completed Tycho's unfinished business through hardships to comfort Tycho's spirit in the sky.
Today, the story of Tycho and Kepler has become a well-known story. ’
