In Wenhua Hall.

The emperor and a group of civil and military officials all stared at Zhao Hao quietly.

Zhang Xianggong was among them. The moment he heard Zhao Hao open the topic with "Xunzi's Tianlun", his calm eyes lit up with admiration.

Bu Gu's true body - his long beard as soft as a waterfall, also moved automatically without wind because of his mood.

"The laws of nature are constant. They do not exist for the sake of Yao, nor do they perish for the sake of Jie. If you respond to them with order, it will be auspicious. If you respond to them with chaos, it will be disastrous!"

Wonderful, wonderful, using the words of the sage to open the topic is both safe and clever, yet it is sufficient to express your own point of view and difficult for people to refute easily!

Let Bu Gu continue listening.

After Zhao Hao recited the "Heavenly Theory" in a rhythmic manner, he explained it aloud:

"What the later sage meant is that the laws governing the operation of heaven and earth are eternal and unchanging, and are not affected by the wisdom or stupidity of the monarch. Using the same celestial phenomena to explain a peaceful world is a good omen, and using the same celestial phenomena to explain a chaotic world is a bad omen!"

"Is social peace or unrest determined by heaven? The answer is no! The movement of the sun, moon and stars faced by Xia Yu and Xia Jie was no different. But under the same celestial phenomena, Yu brought order to the country, while Jie caused the country to fall into chaos and perish. So peace and unrest are not determined by celestial phenomena!"

"Solar and lunar eclipses occur, winds and rains blow at unseasonable times, strange stars appear by chance, and the earth shakes and cracks. The people ask in horror, what is going on? The answer is, nothing. It is just a normal but relatively rare natural phenomenon. A gentleman may feel strange about it, but it is wrong to be afraid of it."

"These phenomena will occur in any era. When the monarch is wise and benevolent, even if these phenomena occur at the same time, there will be no harm. When the monarch is incompetent and tyrannical, even if none of these phenomena occur, the country will still be in chaos."

"Why does it rain when a rain-making ceremony is held? The answer is nothing. Because it will rain even if you don't hold a rain-making ceremony. Beating gongs and drums to rescue when a solar or lunar eclipse occurs is just a ceremony to decorate the court. It is ridiculous to really believe that it is a punishment from the gods..."

Zhao Hao wanted to say, "Either stupid or bad." But his disciples thought that was provocative, so they persuaded him to change to a milder statement.

Then, Zhao Hao's sharp eyes swept across the officials in the Wenhua Palace, and he deliberately lingered on the face of the young elder for a while, then raised his voice and said:

"So, instead of blindly fearing natural disasters, why not actively explore the laws of nature? Instead of making up all kinds of stories to explain natural disasters, why not grasp the changes in natural laws and make use of them? Instead of using natural disasters to restrict and scare the king, why not discuss the matter objectively, use history and reason to be upright and make the king Yao and Shun?!"

Emperor Longqing resisted the urge to applaud enthusiastically, but the upturned corners of his mouth revealed why he insisted that Zhao Hao ascend the stage for the imperial lecture.

Because science is royalist...

Well, everyone in the science field is talented and speaks well. I really like science.

The young cabinet minister's face became increasingly gloomy. He had thought that Zhao Hao would express a different opinion, but he did not expect that this evil creature would use the words of the sage to express his own views.

It not only expresses his views clearly, but also makes it difficult to directly denounce them as heresy.

After all, the next best thing to Confucius is Mencius and Xunzi. How can the younger generation accuse Xunzi of talking nonsense?

This sly boy is always so cunning!

~~

However, Lord Xu looked calm, with a scornful smile on his face.

That's it? It's just the same old story.

Even if you explain it clearly, it is the words of a later sage. What does it have to do with you or science?

As if sensing the Prime Minister's contempt, Zhao Hao turned around, smiled at Xu Jie and said:

"For thousands of years, Xunzi's words have been regarded as just one person's opinion because of the lack of strong evidence. But today, I, a humble boy, will use science to prove to everyone that Xunzi's words are correct!"

In the hall, all the ministers looked very interested.

After all, Zhao Hao is no longer an unknown person. This guy once gave lectures at Lingji Palace, taught five successful candidates in the same imperial examination, flew into the sky in a hot air balloon... and almost captured Yuan Fu in it.

All of the above is enough to make everyone put aside their arrogance and listen carefully to his science to see if it can prove that the laws of nature are constant!

"First, let's start with the structure of heaven and earth."

Zhao Hao waved his hand, and his two disciples, Wang Dingjue and Yu Shenxing, carried in a large wooden board covered with silk cloth of different colors.

After the two men placed the wooden board the size of a bed on the table, Zhao Hao lifted the red silk cloth, and a huge fiery red sphere appeared in front of everyone.

“It’s the sun!”

Then he peeled off the silk cloths one by one, and under each piece of silk cloth was a sphere of different colors and sizes.

"This is Mercury. This is Venus. The red one is Mars. The orange one is Jupiter. The yellow one is Saturn..."

"Our ancestors discovered very early on that these five stars were different from other stars, so they were named after the five elements. In fact, these five stars, together with the sun and the moon, are all the stars closest to us."

"And here," Zhao Hao touched the blue sphere between Venus and Mars, paused deliberately, and then said slowly:

"It is the position of our earth, representing the place where we observe the sun, moon and stars."

In order to make everyone listen, Zhao Hao deliberately concealed the concept of the earth, and only explained the blue sphere between Venus and Mars as the observation point.

The above is basically within the scope of the traditional "Hun Tian Theory", and the ministers have no objection.

The Hun Tian theory is an astronomical model that has been passed down since ancient times and is also the mainstream of the Ming Dynasty.

They believed that the earth floated in the air, so it swirled and floated, which was the so-called "the earth has four movements". Once a celestial sphere enveloped the earth, the sun, moon and stars attached to the celestial sphere and orbited the earth.

Zhao Hao's next sentence made everyone change their expression.

"But the Hun Tian theory is wrong. Because among the sun, moon and stars, only the moon revolves around the earth. The five planets of gold, wood, water, fire and earth and the earth we live on all revolve around the sun!"

In the hall, the ministers all showed expressions of surprise, and many of them wanted to speak on the spot.

However, the rules for lectures on imperial court were strict. No one, including the emperor, could interfere until the lecturer had finished his explanation.

Otherwise it will be considered as impolite.

So Zhao Hao could finish explaining his theories with ease.

The two disciples pulled off the black silk cloth covering the wooden board.

The emperor and his ministers saw concentric elliptical copper orbits with the sun at the center.

The only exception is the orbit of the Moon, which revolves around the Earth.

The tracks are connected to the spheres by thin copper rods, forming a simple, orderly and clear model.

"This is the model of the solar system. We humans live in the solar system." Then Zhao Hao announced loudly: "Through this model, you can demonstrate all celestial phenomena related to the sun, moon and five planets. Once you master the scientific calculation method, you can accurately predict the time and direction of all celestial phenomena!"

Then Zhao Hao used this model to demonstrate the causes of astronomical phenomena such as solar eclipses, lunar eclipses, and lunar phases.

Although he did not demonstrate the 'Venus Conjunction with the Moon', anyone who was not a fool could understand that if his system was valid, then the so-called 'Venus Conjunction with the Moon' was nothing more than Venus and the Moon just happening to come together during their movement.

But he must first prove that this system can be established!
