Hearing Zhan Qiulang's question, the civil and military officials present were stunned.

is worthy of being the first astrologer in Southern Xia, and he asked such an in-depth question at the beginning.

This is a philosophical question that even the astrologers of the empire may not be able to answer.

Lin Yun, a teenager, how could he answer?

Everyone originally thought that it was impossible for Lin Yun to answer such a question. But who knew that Lin Yun didn't even think about it, so he replied directly: "All things in the void, since their birth, have been moving with each other, and there is no so-called center at all. ”

Hearing Lin Yun's words, everyone present burst into laughter.

"No center? What kind of fallacy is this? What! ”

"Everything has a center, how can everything in the void not have a center? I think he just doesn't know where the center is, that's why he deliberately said such ridiculous things! ”

Everyone was laughing, but Zhan Qiulang was shocked.

Because what Lin Yun said just now was completely consistent with the content recorded in the book in his hand!

All the people who were mocking Lin Yun suddenly shut up and quieted down after seeing Zhan Qiulang's expression.

The originally noisy palace hall also fell silent at this moment.

Everyone looked at Zhan Qiulang in surprise, and wondered why Zhan Qiulang showed such an expression.

After seeing a long sound, Zhan Qiulang took a deep breath and asked Lin Yun solemnly: "What is the basis for saying that everything in the void has no center?" ”

While operating the forging furnace, Lin Yun said to Zhan Qiulang: "The Divine Domain, the Demon Domain, and the Tianwu Continent all do periodic movements around the sun, and they all have the sun as the center. ”

"The sun and countless stars move around the center of the galaxy together, forming a vast and boundless galaxy."

"And beyond the vast galaxy, there are thousands of similar galaxies. They surround each other and move each other to form a larger system of galaxies. ”

"There is not only one galaxy group, but also thousands of them. They are also in constant motion...... All in all, everything in the void is moving with each other, and there is no such thing as a center. ”

After listening to Lin Yun's words, all the civil and military officials present were deeply shocked.

The void they originally knew was only limited to the galaxy that could be glimpsed in the night sky. Never imagined what was beyond the galaxy.

At this time, Lin Yun told them that there were thousands of galaxies outside the galaxy, and they formed a larger system of galaxies.

Even outside the unimaginably large galaxy clusters, there are thousands of galaxy clusters.

This completely subverted their perception of all things in the void!

"Is the void really that big?" Nangong Yan looked at Lin Yun with burning eyes and muttered in her mouth.

As the princess of the Nanxia Kingdom, Nangong Yan is not only talented and beautiful, but also knowledgeable and extremely keen to explore mysteries.

Since she first boarded the stargazing platform at the age of six, Nangong Yan has been out of control and completely sunk into the gorgeous void.

Her obsession with the void can even be described as fanatical.

Her biggest dream in this life is to uncover the mysteries of astronomy, explore the boundaries of the void, and trace the origin of all things.

She firmly believes that the galaxy observed by humans is definitely not the whole of everything in the void. There must be something else beyond the known galaxy.

It's just that human observation technology is limited, and the exploration of the void is still in its infancy, so no one can confirm this.

In the entire Nanxia Kingdom, Nangong Yan was the only one who firmly believed in this view, so she felt very lonely.

And Lin Yun's appearance completely rescued her from loneliness and made her feel as if she had found a confidant.

Lin Yun just said that there are thousands of galaxies outside the galaxy, which aroused her curiosity and made her feel extremely excited. It was as if it was a timely heavy rain, watering the thirsty land and nourishing her for many years.

"You said that there are thousands of galaxies beyond the galaxy, but why can't we observe them?" Zhan Qiulang asked Lin Yun suspiciously.

The existing astronomical books only record that there is no center for all things in the void, but they do not say that there is anything beyond the Star River.

Even things that are not recorded in the books, Lin Yun can say them so clearly and methodically, it is really difficult to be convinced.

Lin Yun glanced at Zhan Qiulang with disdain, as if he was contemptuous of the frog at the bottom of the well: "The other galaxies outside the galaxy are very far away from us. ”

"Even the closest alien galaxy to us would take millions of years to reach at the speed of light. And the farthest alien river from us, it will take tens of billions of years for light to arrive! ”

"After crossing such a long distance, the light they release will become very faint, so faint that it will be completely obscured by the brilliance of our galaxy. That's why we can't observe those alien rivers. ”

After listening to Lin Yun's remarks, Zhan Qiulang and several astrologers fell into a deep shock.

How fast is the speed of light?

Ordinary people may not have a concept, but they who are engaged in astronomical research are very aware of this concept.

In just half a second, the light could circle the Tianwu Continent for a circle.

In just ten seconds, just the light could reach the Divine Domain or the Demon Domain from the Tianwu Continent.

At such a fast speed, it would take millions of years to reach the nearest alien river. I can't imagine how vast the void is!

Although this sounded incredible, they had to admit that Lin Yun was indeed very powerless in thinking and philosophical truth.

Regardless of whether Lin Yun's remarks were correct or not, Zhan Qiulang raised the question about the center of all things in the void, and Lin Yun answered it correctly, so there was nothing to continue to dispute.

"You got the first question right." Zhan Qiulang nodded approvingly, and then turned the pages of the book backwards.

When he turned to the penultimate page, Zhan Qiulang suddenly stopped and asked Lin Yun, "May I ask little brother Lin Yun, what is the reason for the regular periodic movement of the celestial bodies?" ”

Hearing Zhan Qiulang's question, everyone present was confused.

Even some scholars frowned in contemplation, clearly stumped by the question.

They had never even thought about this philosophical esoteric question before, let alone answered it correctly.

As an astrologer, Zhan Qiulang himself has been troubled by this problem for many years. At this time, he happened to turn to this question in the astronomy book, and he happened to use this question to ask Lin Yun.

He believed that even the questions he couldn't understand himself, and it was absolutely impossible for the young man in front of him to understand them.

After Zhan Qiulang asked this question, Nangong Yan looked at Lin Yun with anticrative and eager faces, revealing a look of eagerness for knowledge.

This is also the question she has dreamed of trying to figure out.
