Chapter 1933

Xia Yuanqiu then said, "do you mean that the solar eclipse occurs once every seven years?"

Wen Cheng nodded: "it seems so at present, and it's on a certain day in midsummer, maybe July, maybe August, just between these two months."

Xia Yuanqiu also said: "as far as I know, most eclipses occur on the new moon, that is, the first day of the lunar calendar. Today is July 28, that is to say, there are two days left. Maybe we can see the eclipse!"

Wen Cheng asked: "how do you know that the eclipse will take place in Shuozhi? Can't it be another day? "

Xia Yuanqiu scolded himself and said with a smile: "it's not that it can't be any other day, but most of it is on this day."

"Most? How many eclipses have you seen? " Wencheng continued to publish.

Xia Yuanqiu said: "it's not that I've seen it, but it's that some people have seen it. They wrote down the days of the eclipse and made a deduction and calculation. They found that the probability of the eclipse on the new moon is much higher than that of the others."

Wen Cheng then asked, "who is the predecessor you are talking about? Does he know what an eclipse is? How and why did the eclipse take place? "

How and why solar eclipses occur is known by Xia Yuanqiu. It can be said that everyone in the 21st century knows it. But how can she explain it to Wen Cheng?

After thinking about it, she simply told him that an astronomy maniac like Wencheng would be crazy if he didn't make it clear.

"Well, it's not convenient for me to know who the predecessor was. As you know, some people don't like to be famous and don't want people to know about his existence. He did mention how the solar eclipse was formed. If you want to know, I can tell you in detail!"

Wencheng quickly nodded: "of course, I want to know. Please tell me quickly."

Xia Yuanqiu pointed to the sun in the sky and said, "you should know that the sun is actually a sphere, a very big sphere, which gives off light and heat. Where we live is the earth. We live by the sunlight from the sun. In the vast universe, there are many such spheres, which are called planets and the earth The sun and the moon are just one of them. Just like the sun and the moon, the earth is constantly rotating and moving. According to the fixed space-time orbit, the sun and the earth are moving in a straight line. The formation of solar eclipse is that when the moon, the sun and the earth are moving in a straight line, the moon will block the light from the sun to the earth, and The black shadow behind the moon just fell on our earth, forming a scene of no light and dark, but this is only a short moment, because the three planets are still in constant operation, the formation of a straight line is only a temporary stay, and it will soon return to light. "

Wencheng was shocked. This is the first time he has heard such a bold idea since he entered the industry.

Wen Cheng asked, "your ideas are really shocking."

Xia Yuanqiu shook his head: "what I'm talking about is not imagination, but fact. The real fact, the real fact, there is no empty word."

Wencheng was surprised and said, "so you mean that all of us, in fact, live on a big ball?"

Xia Yuanqiu nodded: "yes, it's a ball. When you stand here and look at the distant stars in the sky, have you ever thought that in fact, on other planets, there are also people or some creatures looking at you in the same way? In your eyes, is that distant star a ball? "
