"Xiao Huan, I have flipped through a few pages of this book "The Vast Starry Sky". It is indeed very imaginative, but it is full of mistakes.
He said that the place we live in is actually a blue round sphere rotating in the void.
This is the opening sentence, there are too many mistakes.
First, if we live on a sphere, then there is an upper side and a lower side, so why does no one fall into the void?
Second, if we live on a huge sphere, why does it feel like the earth extends forward infinitely on an infinite plane, such as rivers and lakes, but how can it be as flat as a mirror?
Third, it says: The planet is rotating at high speed, revolving around the big and small sun, so there are spring, summer, autumn and winter.
Fourth, the planet is rotating, so there are day and night.
Fifth, it seems reasonable to revolve around the sun, because when the sun is far away, we are cold; when the sun is close, we are hot. Therefore, the cycle of spring, summer, autumn, and winter begins again and again.
Sixth, saying that the planet rotates is the biggest fallacy, and I can prove it right away."
Ai Xunhuan asked curiously: "Can you prove that the planet does not rotate? This is an incredible skill."
Tian Yueling said: "This is too simple and clear at a glance."
After saying that, Tian Yueling jumped up with his feet in the air.
Ai Xunhuan said: "Prove it to me."
Tian Yueling smiled and said: "I have proved it."
Ai Xunhuan asked curiously: "You just jumped a little, what's the proof?"
Tian Yueling said proudly: "I jumped into the air, which is the most powerful proof. You see, when I jumped into the air from here, I stayed in the air for a while, and when I fell, I was still in the same position. If the planet was traveling at a high speed,
It's running, how can I fall back to where I was?"
Ai Xunhuan couldn't help but laugh. Of course Tian Yueling didn't understand inertia, and this kind of thinking was normal.
Tian Yueling looked ugly because Ai Xunhuan didn't take it seriously and took it as a joke.
And Tian Yueling felt that she was so reasonable and 100% correct.
Tian Yueling was angry, put her hands on her hips and said, "Xiao Huan, don't giggle. If you can't convince me, see how I deal with you."
Ai Xunhuan also found it difficult to convince someone with no knowledge of physics to understand the rotation of the planet.
"Sister Yue Ling, have you ever jumped off your back when riding a unicorn-scaled beast?" Ai Xunhuan thought for a moment and asked.
Hongwu Continent rides a unicorn with scales. The scales of this scale beast have defensive functions, are fast and stable, and are a universal means of transportation.
"Xiao Huan, riding a unicorn-scaled beast is our basic skill." Tian Yueling's face exuded confidence.
"Then when you are riding a unicorn-scaled beast and you jump into the air, why do you return to the beast's back? According to your theory, when you jump into the air, the unicorn-scaled beast is flying forward, but you are not there
How can you get back to the beast at such a forward speed? The most you can do is grab the unicorn-scaled beast's tail."
"This!" Tian Yueling couldn't answer, and his face suddenly turned red.
But she still refused to admit defeat and said forcefully: "Actually, there are three situations when flying on the unicorn scale beast. I have summarized: First, if the scale beast suddenly accelerates after jumping on the unicorn scale beast, then where will I land?
Behind. Second, if the speed of the scale beast remains unchanged, then I will fall at the same position. Third, if the scale beast suddenly reduces its speed, my position will fall ahead. So you only mentioned one of the situations.
.”
"The three situations are normal. The fundamental reason is that when you take off, you have the same speed as the scale beast at that time. Therefore, if the scale beast accelerates, you will fall behind. If the scale beast slows down, you will fall behind. This is called the inertia of the object.
." Ai Xunhuan explained.
"Inertia!" Tian Yueling recited it several times, unable to understand it, but unable to refute Ai Xunhuan, and asked again: "You mean everything written in "The Vast Starry Sky" is true, then why did I not
Falling into the void, and the water in the rivers and oceans did not fall into the void?"
Tian Yueling asked about her biggest winning hand, and she felt that this truth was irrefutable.
"Gravity." Ai Xunhuan replied.
"What is gravity?" Tian Yueling was confused.
"To put it simply, any two objects will attract each other, forming an attraction called universal gravitation. For example, there is an attraction between a chair and a table, or between you and me."
"Giggle!" Tian Yueling laughed heartily. Finally, she won. She said proudly: "Gravity is so ridiculous. There is an attraction between the chair and the table. Why are the two motionless? There is an attraction between us. Why?
We were not held together by the force of attraction."
"It seems that Sister Yue Ling likes to hug me. That's because the biggest attraction is the attraction between all things and the planet. Why do we have weight? It's the force generated by the planet attracting us. The planet has the greatest mass, so
Its attraction is the strongest, and the attraction between us is relatively small, so small that it can be ignored. The planet exerts a strong attraction on the humans of Hongwu Continent, the water in the rivers and oceans, and the aura, so none of them have
Fall into the void."
Tian Yueling was silent for a while, then said with a smile on his face: "You almost scared me. If there is universal gravity, why do birds fly in the sky without being attracted by gravity? If there is universal gravity, why do big trees grow towards the sky? If there is universal gravity, why do big trees grow towards the sky?
If there is gravity, why can white clouds and black clouds float in the sky?"
"Birds fly in the air because of buoyancy. When a bird flaps its wings, it generates buoyancy, which offsets its own weight. White clouds and black clouds float in the sky because they are buoyant by the air, and big trees grow toward the sky.
That's because they are naturally phototropic."
"Inertia, gravity, buoyancy, phototropism." Tian Yueling felt that her brain was going to explode. These terms made her feel baffled and unable to refute, which made her very uncomfortable.
The key is that she realized that no matter what refutation theory she put forward, she would be defeated by Ai Xunhuan. When a mentally retarded child became a master of debate, Tian Yueling was speechless.
"Are you really a pleasure-seeking young master?" Tian Yueling asked deeply.
"Sister Yueling, uh, let's put it this way, the Ai family's bloodline has awakened, and the knowledge imprinted in the soul by the Ai family has been unlocked." There was no other way, Ai Xunhuan used some legends from the Hongwu Continent to convince Tian Yue.
Ling, it would be bad if he were taken as some old monster.
"That's great!" Tian Yueling was overjoyed.
Ai Xunhuan stopped mentioning astrophysics, which he was proud of, and concentrated on eating meat.
The Tian family was really nice to Ai Xunhuan, and changed it to two kinds of meat with full texture. Knowing that he didn't want to eat sweets, they also changed to a kind of soft, white grain.
Hongwu Continent called it Lingmi, with plump grains and fragrant fragrance. Ai Xunhuan ate it regardless of his fat body. This chapter has been completed!
