"I guess it's the right hand." Zhao Xi said unexpectedly.

Li Qingzhao scratched Zhao Xi's nose and said, "You little traitor, didn't you say you would win the bet with Sister Li? Why did you change your mind?"

"I still think Dad is more cunning. You all guessed right. How can Dad teach? So it must be the right hand." Zhao Xi explained to Li Qingzhao in a low voice.

"Watch it."

Zhao Huan raised his arms to the same height, a barely perceptible smile appeared on the corners of his mouth, and he loosened his hands, and the two gold ingots fell to the ground.

Bang!

Two gold ingots fell from the sky and hit the bluestone slabs, making only a sound.

"How is this possible!"

Seeing this scene, Li Qingzhao's face showed extreme surprise and she couldn't help but exclaim.

The expressions of the others were exactly the same, with their mouths wide open and their eyes wide.

"That's impossible!"

Li Qingzhao's beautiful eyes widened, and her pretty face no longer had the calmness and confidence she had before. She shook her head and said.

Zhao Kai, who was standing by, also opened his mouth slightly in surprise, and was no less surprised than Li Qingzhao.

Zhao Xi looked depressed: I guessed the beginning, but not the ending. It was so unconventional.

When dropped from the same height, heavy objects will definitely hit the ground before light objects. This has been a concept that has been deeply rooted in their minds for more than a decade.

But what they saw clearly just now was that the two stones of different sizes fell to the ground at the same time!

"The government must be cheating. This is just a circus, right?"

Li Qingzhao looked up at Zhao Huan and said in a firm tone.

"I knew you would say that."

Zhao Huan shrugged and said nonchalantly, "If you don't believe me, try it yourself."

If the law of free fall could produce different results in the hands of Li Qingzhao and Zhao Kai, then what would it matter if he lost thirty taels of gold to them?

In another world, Aristotle's view on free fall is that the speed of an object falling from a height is proportional to its weight. In other words, a ten-pound object will fall ten times faster than a one-pound object.

On the surface, this theory seemed very reasonable, and everyone believed in its truth. Everyone regarded it as a classic, and no one raised any doubts.

Aristotle remained at the height of his powers until the sixteenth century.

The professors taught this theory seriously to their students, and the students all accepted it respectfully. Only Galileo expressed doubts.

Galileo once witnessed hailstones of different sizes falling to the ground at the same time. According to common sense, they seemed to be falling from the same height.

But according to Aristotle's theory, larger hailstones should fall to the ground first, followed by smaller hailstones, but this was not what Galileo observed.

He conducted many experiments and found that Aristotle's theory was wrong, and he was determined to point out this error.

So one day, the young scientist Galileo walked up the Leaning Tower of Pisa, threw two iron balls of unequal weights down, and used the double-ball experiment to prove the law of free fall.

This is the famous experiment of two iron balls falling to the ground at the same time.

Galileo said: "The surest way to truth is to put experiment before any reasoning, believing that the latter will contain fallacies, and a reasonable experiment cannot be contrary to the truth."

Before Galileo, no one had ever emphasized the importance of experiments so much. Therefore, Galileo was well-deserved to be called the father of modern physics and even modern science by Einstein.

Similarly, in today's world, this truth, which can be understood by doing a small experiment, has not been discovered by anyone because of the ancients' concept of "taking it for granted".

Li Qingzhao picked up two more gold ingots to experiment. When she saw the two gold ingots in her hands also fall to the ground at the same time, she was stunned. Then, she gritted her teeth and said, "White Lady, you try it!"

Over there, Zhao Kai also took out two silver ingots of different sizes from his pocket and started experimenting.

The others also started whispering and discussing.

The reason why a law is a law is that it does not change due to objective conditions. Those who try to challenge the laws of nature, such as Li Qingzhao and Zhao Kai, are doomed to fail.

“Why…why is this happening?”

Looking at Li Qingzhao muttering these words in a daze from afar, it seemed that even the worldview she had built up for a long time was beginning to collapse. Zhao Huan felt a little guilty.

Isn’t it too cruel to destroy their three views with such violent methods?

"Why?" Li Qingzhao looked up at Zhao Huan and asked through gritted teeth, "Why did the two gold ingots fall to the ground at the same time?"

For her now, winning or losing is not important. What is important is that the beliefs in her heart have changed dramatically over the years, and she needs to know the reason.

Zhao Xi also stared at Li Yi with eyes wide open, his big eyes full of curiosity.

Or is it that everyone is like this, eager to know why?

"That's because the speed at which gold falls has nothing to do with its weight. No matter how different the weights of two ingots are, if they're dropped from the same height, they'll always hit the ground at the same time."

Zhao Huan tapped the blackboard and said, "The influencing factor is the g we're going to talk about today, the acceleration due to gravity."

"Gravity isn't just about these two ingots of gold. Why does water always flow down a mountain instead of up? Why do leaves always fall to the ground instead of flying up into the sky?"
