Upon hearing Zhan Qiulang's question, all the civil and military officials present were stunned.
As expected of the number one astrologer in Southern Xia, he asked such a profound question from the very beginning.
Even the empire's astrologers may not be able to answer this profound philosophical question.
How could Lin Yun, a mere young man, be able to answer this?
Everyone originally thought that it was impossible for Lin Yun to answer such a question. But who knew that Lin Yun actually answered directly without even thinking about it: "All things in the void have been moving with each other since their birth, and there is no such thing as a center.
"
Hearing Lin Yun's words, everyone present burst into laughter.
"No center? What kind of fallacy is this? It's such nonsense!"
"Everything has its center, how can everything in the void have no center? I think he just doesn't know where the center is, so he deliberately said such ridiculous things!"
Everyone was laughing, but Zhan Qiulang's face was full of shock.
Because what Lin Yun said just now is completely consistent with what is recorded in the book in his hand!
Everyone who was mocking Lin Yun immediately shut up and became quiet after seeing Zhan Qiulang's expression.
The originally noisy palace hall also fell into deathly silence at this moment.
Everyone looked at Zhan Qiulang in surprise, wondering why Zhan Qiulang showed such an expression.
After a while, Zhan Qiulang took a deep breath and asked Lin Yun seriously: "What is the basis for you to say that all things in the void have no center?"
While operating the forging furnace, Lin Yun said to Zhan Qiulang: "The God's Domain, the Demon's Domain, and the Tianwu Continent all make cyclical movements around the sun, all with the sun as the center."
"The sun and countless stars move around the center of the galaxy, forming a vast and boundless galaxy."
"And outside the vast galaxy, there are thousands of similar galaxies. They orbit each other and move with each other, forming a larger system of galaxy clusters."
"There is more than one galaxy cluster, and there are also thousands and thousands of them. They are all constantly moving... In short, everything in the void is moving with each other, and there is no so-called center at all."
After listening to Lin Yun's words, all the civil and military officials present were deeply shocked.
Their original understanding of all things in the void was limited to the stars that could be seen in the night sky. They had never imagined what was beyond the stars.
But at this time, Lin Yun told them that there were thousands of galaxies beyond the galaxy, and they formed a larger system of galaxy clusters.
Even beyond the unimaginably huge galaxy clusters, there are thousands of galaxy clusters.
This completely subverted their understanding of everything in the void!
"Are all things in the void really that big?" Nangong Yan looked at Lin Yun with burning eyes and murmured in his mouth.
As the princess of the Nanxia Kingdom, Nangong Yan is not only talented and beautiful, but also knowledgeable and extremely keen on exploring mysteries.
Since she first stepped onto the observatory when she was six years old, Nangong Yan has been out of control and completely lost in the gorgeous void.
Her obsession with the void can even be described as fanaticism.
Her biggest dream in this life is to uncover the mysteries of astronomy, explore the boundaries of the void, and pursue the origin of all things.
She firmly believes that the galaxies observed by humans are definitely not all of the universe. There must be other things beyond the known galaxies.
It's just that human observation technology is limited and the exploration of the void is still in its preliminary stages, 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.
The appearance of Lin Yun completely rescued her from loneliness and made her feel as if she had found a soulmate.
Lin Yun just said that there are thousands of galaxies beyond the stars, which aroused her thirst for knowledge and made her feel extremely excited. It was like a timely heavy rain, watering and nourishing the already thirsty land.
She has been hungry for many years.
"You said there are thousands of galaxies beyond the galaxy, but why can't we observe them?" Zhan Qiulang asked Lin Yun dubiously.
Existing astronomical books only record that everything in the void has no center, but they do not say what is beyond the star river.
Even things that are not recorded in books, Lin Yun can explain them so clearly and orderly, which is really hard to believe.
Lin Yun gave Zhan Qiulang a contemptuous look, as if he was scorning a frog at the bottom of a well: "Other galaxies besides the galaxy are very far away from us."
"Even the closest alien star to us would take millions of years to reach at the speed of light. And the farthest alien star would take light even tens of billions of years to reach!"
"After traveling such a long distance, the light they emit will become very weak, so weak that it will be completely obscured by the brilliance of our galaxy. It is precisely for this reason that we are unable to observe those alien galaxies."
After listening to Lin Yun's remarks, Zhan Qiulang and several astrologers were deeply shocked.
How fast is the speed of light?
Ordinary people may not have the concept, but those who engage in astronomical research know this concept very well.
In just half a second, light can circle the Tianwu Continent.
In just ten seconds, light can reach the divine or demonic realm from the Tianwu Continent.
At such a fast speed, it would take millions of years to reach the nearest alien galaxy. It is simply unimaginable how vast the universe is!
Although this sounds incredible, they have to admit that what Lin Yun said is indeed very powerful and philosophical.
Regardless of whether Lin Yun's remarks are correct or not, Zhan Qiulang raised questions about the center of all things in the void, and Lin Yun answered them correctly, so there is nothing to continue to argue about.
"You answered the first question correctly." Zhan Qiulang nodded in approval, and then turned the pages of the book backward.
When he turned to the last page, Zhan Qiulang suddenly stopped and asked Lin Yun: "Brother Lin Yun, what is the reason that causes the celestial bodies to move regularly and periodically?"
Hearing Zhan Qiulang's question, everyone present was confused.
Even some scholars frowned and pondered, obviously stumped by this question.
They had never even thought about such a philosophical and 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 find this question in an astronomy book and used it to question Lin Yun.
He believed that even he himself could not understand the problem, and it was absolutely impossible for the inexperienced young man in front of him to understand it.
After Zhan Qiulang asked this question, Nangong Yan looked at Lin Yun expectantly and eagerly, looking eager for knowledge.
This was also a question she wanted to figure out in her dreams.
