He Qing's eyes widened when he heard this. He didn't expect that Gu Zheng could design a famous experiment while thinking about it.
Perhaps, the brain circuits of geniuses are mostly similar?
Gu Zheng continued, "Therefore, I also speculate that when these objects fall, they can use the force of the wind, just like a flock of birds flying high or a kite soaring into the sky. But if they are heavy enough and have no wings, the force of the wind can be ignored. Regardless of the weight, the time it takes to fall to the ground is the same, and the force it experiences is also the same."
He Qing noticed that he had used two guesses, so he snorted and said with a smile, "Just Lord Gu's guess?"
"I cannot confirm it." Gu Zheng nodded honestly.
But he quickly pulled out a long black stone from his sleeve, tossed it up and down twice, and then continued, "I've also thought, things that are placed quietly must be moved by someone. When they fall to the ground, who is exerting the force?"
As he spoke, he took out a piece of iron with his other hand and placed it on the other side of his palm, some distance away from the black stone. But as soon as he let go, he heard a "ding" sound, and the iron sheet was already attached to the black stone.
"This is a magnet. The iron sheet will be attracted to it and will stick to it. If we assume that the ground beneath our feet is a huge magnet that attracts everything, then it makes sense." Gu Zheng held the magnet in his hand and smiled at He Qing. "This is just a hypothesis. I've been looking for a way to prove it recently."
He Qing could only remain stunned, he had even figured out the law of universal gravitation.
Although this was what He Qing wanted, when she actually did it, she felt an indescribable feeling in her heart, and always felt that she had caused a very remarkable change.
"But this raises a new question. For example, if the stars, sun, and moon hang high in the sky, why don't they fall to the ground? If it's because they're too far away, then I heard stories about meteorites from outer space when I was young, but that doesn't fit the story. I'm still researching this question, so I won't discuss it for now."
At this point, Gu Zheng smiled slightly. "The Way of Nature is indeed profound and fascinating. I wonder if my answer can temporarily resolve Master Zhen's doubts?"
