Chapter 751 Watching the Moon
"It actually happened."

Changsun's face was full of surprise. The comet with its tail hung brightly in the sky. She said in disbelief.

"Do you want to see the moon?" Ji Song suddenly said.

"moon?"

Changsun's eyes lit up and he said hopefully, "Is it okay?"

Ji Song smiled slightly and said, "Of course, Wei Chen has already observed it just now."

"But I may disappoint you. The moon may not be as mysterious as everyone thinks."

After finishing speaking, he did not explain, but adjusted the telescope to the direction of the moon, and then moved out of the way.

Changsun couldn't wait to look at it, and opened his mouth wide when he saw the dim look on the moon and the pits on it.

He looked at Ji Song and said in surprise: "How is this possible? Why are there so many circular potholes on it? It seems like it was hit by something?"

"Oh? I'll come and take a look too."

Before Ji Song could say anything, Li Shimin came to the eldest grandson's seat and looked up.

Sure enough, there were many circular pits on it, just like a person's pockmarked face, which was very ugly.

Cheng Yaojin sneaked up to him at some point. When Li Shimin walked away, he immediately took up his position and looked like the emperor.

"My dear, what is this?"

Yuchi Gong couldn't hold it any longer, pulled Cheng Yaojin away, and looked at the moon regardless of his glare.

"Is this really the moon?" Yu Chigong asked in surprise.

He left the telescope and looked at it with the naked eye. The moon was still so beautiful, quiet, and silently hanging in the sky, as if it had been like this forever.

"What does this mean? Why are there so many craters on the moon? Where's the laurel tree? Where's the moon palace?" Li Shimin was full of doubts and asked several questions at once.

"Should there be Chang'e, Jade Rabbit, and Wu Gang? The already magnificent Moon Palace?" Ji Song said with a smile.

"Shouldn't it be right?" Changsun asked doubtfully.

Ji Song couldn't laugh or cry and said, "My dear, that's a fairy tale. The moon you see now is the most real one."

"It shouldn't be! What about Chang'e? Didn't she live in the Guanghan Palace in the sky? Why are there so many big and small holes there, even worse than my home?"

"To shut up!"

The emperor and empress said in unison.

Cheng Yaojin rolled his eyes, "Yeah, I'd better go and draw circles in the corner!"
Ji Song looked at the moon in the sky and explained: "Actually, there were no such myths a long time ago. They were just people's yearning for a better life. As time went by, these myths gradually emerged."

"There are no laurel trees on the moon, there is no beautiful Chang'e, and there is no Wu Gang who is always cutting down laurel trees. There is only constant protection."

"guard?"

"Yes, it's just protection!"

He pointed at the bright full moon and said, "Where do you think those pits come from?"

"Those are all traces of meteorite impacts. Over millions of years, the moon has prevented countless crises for the earth under our feet."

"In fact, the heliocentric theory has appeared in the academy. They believe that the earth under our feet is round, just like the moon. The reason why people can stand on the earth is just that it is tightly attracted by the earth for some reason!" "The earth under your feet rotates around the sun. Because of the different angles, sometimes it is far away from the sun and sometimes it is closer to the sun, so there are four seasons: spring, summer, autumn and winter."

"But the moon rotates around the earth, and due to the moon's gravity, there will be ebb and flow."

"Then how did day and night appear?" Changsun asked.

"That's because the earth under our feet not only revolves around the sun, but also rotates on its own. During the day, we are facing the sun, so it is day. At night, the sun is behind us, so it is night."

He tried to explain in the simplest terms possible.

But both Li Shimin and Changsun looked confused. They had no such concepts in their minds.

Cheng Yaojin and Yuchi Gong were even listening to the Book of Heaven. They knew every word, but they couldn't understand anything when they were put together.

"Just tell me why the solar eclipse appears." Li Shimin said irritably.

He was very repelled by things that were beyond his control. He didn't like this feeling, so he felt irritable.

"Because the moon just blocks the sun's light."

"like this."

He picked up two fist-sized round stones, placed one in front and placed the other behind.

"You see, when the two stones are staggered, you can see the stone behind, but what if this is the case."

He used the stone in front to block the stone behind, and now everyone understood a little bit.Because when they are facing the stone in front, they cannot see the stone behind.

"This is also the reason why a halo appears after a solar eclipse."

Li Shimin was thoughtful and asked curiously: "What about the lunar eclipse? What is it that blocks the moon?"

Ji Song smiled, replaced the stones on the front and back, and said, "Now the moon is in front of you, and the earth behind you is the earth where we live."

He slowly moved the stone behind him toward the outside and asked, "What did you see?"

Li Shimin was stunned for a moment, a little confused!
The eldest grandson understood something, and said thoughtfully: "Did you see part of the moon?"

Ji Song gave a thumbs up and praised: "Your Majesty is smart!"

"The moon does not shine, it just refracts the sun's light! When the moon turns to the back of the earth, we will only see the scales and claws of the moon. This is what we see when the moon is waning and the moon is full."

He then placed the stone behind completely so that they could not see it.Said: "When the earth completely blocks the sun's rays, that's when a lunar eclipse occurs."

"In addition, lunar eclipses can be divided into three types: partial lunar eclipse, total lunar eclipse and penumbral lunar eclipse. And they will only appear around the fifteenth day of every month."

"The reason why I say these things is to tell Your Majesty that both lunar and solar eclipses are common astronomical phenomena. Lunar eclipses basically occur every year, and solar eclipses occur more often than lunar eclipses. But Due to the different orientations we are in, or because of cloud obstruction, cloudy days, rainy days, and the angle between the sun and us, the number of observations is very few."

"It was no surprise when Li Chunfeng calculated the exact time of the solar eclipse. An astronomical event that can be observed and calculated at any time is just like eating when we are hungry and sleeping when we are sleepy. It is just a kind of It’s just a normal thing, nothing magical about it.”

"So, Your Majesty and Your Majesty, don't worry. Later, I will give a grand lecture to that awesome Taoist priest Li Chunfeng and tell him about his calculation of the time of the solar eclipse. Do you think this will be better?"

Li Shimin was stunned. It was too late to cover up the matter, so why did he tell it publicly?He subconsciously wanted to refuse.But seeing Ji Song's malicious expression, he seemed to understand something.

He looked a little excited, he understood, he understood everything, he finally understood what Ji Song meant.

Anshi doesn’t understand why a solar eclipse is considered ominous, but if it’s a calculated solar eclipse that can be monitored at any time, what’s so mysterious about it?
Who would care about something that is no longer a mystery?Those who wanted to use this matter to sway public opinion, but when everyone suddenly discovered that this was just a farce, how could they still sway public opinion?
