Li Ke said that Taoism is not as harmful as Buddhism. Some people may use examples such as Zhang Jiao, but they must make a clear distinction.
The rise of Buddhism will cause a dynasty to turn from prosperity to decline, and when something like Zhang Jiao breaks out in Taoism, can you blame Taoism? Why didn't Zhang Jiao appear in the early and middle Han Dynasty?
The people can't live anymore, let alone Taoism. Chen Sheng and Wu Guang will follow him whenever they shout. Zhang Jiao is just a reason. The root cause is not caused by Taoism, but Buddhism can really turn a country from prosperity to decline. , this is the fundamental gap.
Yuan Tiangang and Li Chunfeng looked at each other, and then said seriously: "Your Highness, since we are officials in the imperial court, we must contribute our own strength to the Tang Dynasty."
"Well, actually your knowledge in astronomy and geography is of great use." Li Ke said with a smile.
"Astronomy and geography?" The two of them probably understood what it meant.
"Yes, I call the knowledge about observing stars as astronomy, and the knowledge about mountains, rivers and other aspects as geography." Li Ke nodded slightly, "Your knowledge inheritance in astronomy is worth cultivating. But I I have a question, do you think the earth under our feet is round, so what is going on with those sun, moon and stars?"
"We Taoists support the Hun Tian theory. Although there has always been a school of thought that covers the sky, in fact we have multiple angles to prove that the Hun Tian theory is true." Li Chunfeng said.
"Including long-distance observation of distant mountains, ships, etc., the tops are exposed first, and then the bottoms are exposed. This proves that the earth is arc-shaped, and the height changes of the sun and the moon can also explain this." Li Chunfeng said. Li Ke explained.
"Well, I know, the earth under our feet is actually a sphere. Have you ever thought that the sun, moon and stars we see are actually the same existence as the earth under our feet? It's just that they are too far away from us. , so we only saw a little bit." Li Ke asked with a smile.
"Ah?" Yuan Tiangang and Li Chunfeng were both stunned.
"Then...if that's the case...how far is the distance? The universe is so big..." The two people's minds instantly felt confused.
Li Ke was a little surprised. He just mentioned that the sun, moon and stars were the same as the earth under his feet. Li Chunfeng thought about the distance. Obviously, he had a concept in his heart. A ball as vast as the earth under his feet, in the sky It's just such a small dot in the middle, and the distance is obviously extremely far.
Even considering the vastness of the universe, I can only say that excellent people are indeed geniuses.
"Indeed, there are actually data that can be used to calculate these things. If you two are willing, I can tell you how to calculate these things when you have the opportunity, but the premise is that you have to learn my new math here."
"Also, I have another idea. Since you are all proficient in observing the sky at night, have you ever thought that it is not the sun, moon and stars that revolve around us, but the earth under our feet and part of the stars that revolve around the sun? "As Li Ke said this, he simply stretched out his fingers to dip his fingers into the cold tea in the tea cup, and started drawing on the table in front of him.
After drawing out the approximate galaxy diagram of the solar system, Li Ke asked with a smile: "Is it possible that the sun, moon and stars move like this? I call this a galaxy, and the stars further away are countless The universe is made up of galaxies like ours? Is it possible that the bright stars in the sky at night are the sun that is farther away!"
Li Ke doesn't mind throwing some bombs at them, because astronomy is actually not afraid of throwing theories at them. It's not the same as other things. The sooner astronomy establishes a theory, the better. Anyway, research is slow, so let them take their time. Just research.
And don’t underestimate the determination of the ancients to verify these things. There are really many geniuses. Once they get on the right path, many of their theories that could not be verified in the past can now be verified, such as the four seasons throughout the year, such as It is said that it is cloudy and sunny and the moon is missing.
"This..." Yuan Tiangang and Li Chunfeng were completely stunned.
They were stunned by Li Ke's bold idea, but looking at the increasingly faint galaxy map on the table, there seemed to be an inexplicable magic in it, attracting them.
"Your Highness, could you please elaborate on this?" Li Chunfeng felt like a cat scratching his heart.
"It's actually very simple. For example, if I name the land under our feet the earth, then if the sun is a sphere that emits heat and light, when the earth rotates around it, then as a sphere, part of it will always be exposed to sunlight. When the earth revolves around the sun, it rotates in one direction, so we have day and night, and the sun rises in the east and sets in the west."
"So why is the moon that revolves around the earth not hot when it shines on the earth? Is it possible that its bright side is actually illuminated by the sun's rays? Because it is far away, we can see that it is also glowing."
"Just like on our earth, when it is daytime, this bright side, if we stand on the moon, will the earth we see also shine? Because it is far enough away, we can't see the details."
"It's understandable that the moon is cloudy and waning, because when it rotates around the earth, the light from the sun is sometimes blocked by the earth, so it can only illuminate part of the light, so we can only see The new moon, the half moon, and finally the full moon.”
"How long it takes for the moon to revolve around our earth is one month, and how long it takes for the earth to revolve around the sun is called a year." Li Ke smiled and told about the basic astronomical knowledge of future generations to about three people. .
Li Chunfeng and Yuan Tiangang were already dumbfounded.
Because Li Keyue talked, they kept comparing it with the knowledge of the sun, moon and stars in their minds, and then they discovered more and more that what His Highness King Qin said... was a complete theory, a seamless theory!
Everything has found evidence, all year round, spring, summer, autumn and winter, why it is hotter in the south and colder in the north.
Why do the four seasons rotate throughout the year?
"You can even think about why the earth revolves around the sun, and what kind of force makes so many stars revolve around it. If the surroundings of our earth are empty, why do we still have things falling? On the ground?" Li Ke said with a smile.
"Your Highness... Chunfeng has met His Highness, no, Chunfeng has met Sir. I wonder if Chunfeng will have the opportunity to learn from His Highness?" Li Chunfeng stood up directly, then bent down and gave a big salute to Li Ke.
The same goes for Yuan Tiangang next to him. Li Ke shocked them too much!
"You two are excused." Li Ke smiled and waved his hand to let the two of them excuse themselves, and then said: "So I said, your Taoism still has some uses, but I know this knowledge, but I don't know why. , there are some things and some laws that you need to find, such as numeracy, because you know a lot of knowledge, you may be able to calculate how far the moon is from our earth."
"How far is the sun from our earth?"
"Everything in the world has its own laws, and these laws can be expressed by numbers."
"So, if we want to figure out the relationship between these astrological phenomena and natural phenomena such as wind, rain, thunder and lightning, we need some geniuses. I think you Taoists all over the world must have some talents in this field."
"I can build a school here in Chang'an to teach this group of people this knowledge, and then record the knowledge you have studied. I will print it into a book and pass it down from generation to generation. Your names will definitely be there in history." Li Ke smiled and said.
Sun Simiao felt a little helpless when he heard this. Hey, I'm familiar with this.
