I am a primitive

After a while, Han Cheng looked at the crowd and asked with a smile.

Everyone scratched their heads in doubt, and then continued to stare at the fruit, but also did not see a single flower.

Wu and Shishi also found nothing.

"Is the surface of this round fruit uneven?"

Han Cheng smiled and said to everyone.

After being reminded by Han Cheng, everyone immediately realized that this was indeed the case.

It's just that after a sudden, they became confused again, because they didn't understand what it had to do with the question they asked the Son of God.

"If this fruit is enlarged vigorously, will these small protrusions on the surface of the fruit become like these peaks and hills? Are the textures on the surface of the fruit the same as the gullies we see? ?

The earth we live on is just like the fruit in my hand. Although the surface is uneven, it is still a ball. "

Han Cheng smiled and said to everyone in the tribe.

Some people didn't react for a while, but some people understood something.

The stone moved his eyes away from the round fruit in Han Cheng's hand, and landed on the hill behind the courtyard. At the same time, the one he had seen before, which was much bigger and higher than the hill, appeared in his mind. Mountain.

After looking at it for a while, he turned his gaze back to the distant fruit held in Han Cheng's hand. Looking at the small bumps and shallow grooves on the surface of the fruit, his expression gradually became extremely shocked.

Such a tall mountain peak is like these small protrusions on this fruit on the earth, so how big is the earth that the Son of God said!

Seeing Shi Shi's expression, Han Cheng smiled. He knew that this smart guy understood what he said.

"The reason why we feel that the land we live on is flat is because the earth we live on is really too big, and there are high mountains and rivers on the surface to block each other. We usually don't realize such a small gap. not come out.

But when you get to a place where the field of vision is wide enough and the ground is flat enough, you can realize that the earth is round.

At that time, when we saw a tree growing in the distance, the first thing we saw was the top of the tree, and the last thing we saw was the bottom of the tree..."

Han Cheng smiled and continued to popularize science with these people in the tribe.

In the past, Han Cheng had a plan. When people in the tribe asked how the mountains and rivers came from, they would bring up the legend of the great god Pangu who opened up the world.

When asked about the shape of the earth, explain it in terms of the round sky.

Because if it is explained in this way, it is very similar to what everyone usually sees, which can make people understand better.

But today, his thoughts have changed all of a sudden.

Because he realized that if he really did this, the future descendants of the Qingque tribe would not know how many detours they would take.

I don't know how many years it will take to know that the sky is endless and the earth we live on is round.

Compared with such things, the difficulty of understanding at this time is not difficult at all.

And when talking like this, Han Cheng also had a bold idea.

After he released the fact that the land he lives in is a huge sphere, later on, among the descendants of the Qingque Tribe, will anyone raise the idea that the world is so big that I want to see it?

Then he took the fleet on a long voyage, started the feat of sailing around the world, and made great geographical discoveries along the way.

Then began the era when the descendants of the Qingque tribe spread all over the world, and brought back all the peppers, sweet potatoes, corn, potatoes, etc. from the Americas, and made Mandarin the only official language by the way...

This thing, just thinking about it, makes people feel very exciting.

"Actually, the earth is not just a sphere, it is always rotating."

Han Cheng's speech was so popular today that he didn't even peel the rabbits. Together with Wu and the others, they came to the big green brick house and told everyone more about astronomy and geography.

Because the inside of this room is much warmer than the outside.

At this time, more people came to listen to Han Cheng's talk.

After thinking about it, Han Cheng asked all the interested people in the tribe to come and listen to the lecture.

It's also time to give everyone in the tribe a good science on these aspects of knowledge.

Knowing these aspects of knowledge can greatly broaden the vision of everyone in the tribe, and will subtly make people's pattern bigger.

After a certain level of development, it will not be arrogant to think that it occupies the center of the whole world, and start to be complacent.

After everyone came here, Han Chengcheng began to tell everyone in the tribe about the rotation of the earth.

After such words were spoken, the people in the tribe were even more surprised.

For them, this is even more incomprehensible than the earth of life is a sphere.

The earth is always spinning, and I and others have never felt it!

I remember when I was not grown up, I would turn around for a while, and my head would get dizzy.

The earth in my life is always turning in circles, so why don't I feel dizzy?

"This is because the earth only rotates once a day, and it rotates very slowly, so you don't feel dizzy. If you don't believe me, you can slowly rotate once on the ground and try to see if you still feel dizzy?"

Han Cheng smiled and said to those people in the tribe who were curious about his head not getting dizzy.

"Why is there day and night? Why does the sun rise in the east and set in the west?"

After a few people turned around slowly according to what Han Cheng said just now, and found that their heads were not dizzy at all, Han Cheng smiled at the crowd and threw out this seemingly simple but enough to make them lose their hair. question.

Sure enough, as Han Cheng expected, after these two questions were asked, everyone in the tribe was immediately blinded.

Why are there day and night?Why does the sun rise in the east and set in the west?

This……

These things have been like this since they started to understand!

That's how they exist, why not!

Everyone scratched their heads, even Wu, Yuan and Shitou, who thought they were smart, were left speechless by this seemingly ordinary question.

Han Cheng couldn't help smiling when he saw this.

These two very common problems at first glance were actually unsolvable problems before the development of modern science.

The ancient ancestors, faced with such unexplainable problems, began to give full play to their own thinking, so myths and stories representing mysterious powers such as the Golden Crow and Xi He driving the sun chariot appeared.

"It's because the earth is spinning."

After waiting for a while, Han Cheng began to explain the reason to everyone.
