"Yes, that is exactly what I meant, Master Helram."

Lin En nodded, looked around at everyone present, then rotated the newspaper in front of him half a circle and pushed it in front of everyone.

"I don't know if you have read this week's Magic Weekly. The legendary wizard Harolf proposed that gravity may exist in all objects, not just the continent beneath our feet."

At this point, Lin En was also somewhat emotional. After reading the "paper" published in "Magic Weekly", he was surprised to realize that this was just the initial concept of gravity. He just didn't know how far this legendary wizard had studied... whether he had figured out the law of gravity, and whether he knew the essence of gravity...

In any case, this just proves his theory, because in the description of this paper, gravity is not just a force that pulls downward, but it affects the entire body and may even affect and distort space.

"Lord Harof's argument is indeed brilliant and irrefutable, but using it as the only evidence to completely refute the flat earth theory still lacks some persuasiveness." Hellram said thoughtfully. In fact, after reading the manuscript, he was more inclined to believe that the flat earth theory was wrong.

But Hellram also knew that this was a theory that was enough to shake the entire wizarding world's understanding of the world. It was conceivable how much controversy it would cause once it was published in "Magic Weekly", so he had to be cautious.

"I have seen your star map, and the theory of rotation and revolution mentioned above is also very interesting. Let me send this theory to several great wizards who have made achievements in gravitational research. If I can gain their approval, it will not be too late to publish it in Magic Weekly." Hellram said solemnly.

"Of course there is no problem with that. The truth can withstand any form of testing!" Lin En nodded. What he wrote in the manuscript were the purest theories. It would be great if they could be confirmed by professionals.

"Then let's stop talking about the flat earth theory and the planetary theory." Hellram skipped this topic, then took out another manuscript and continued. "This law of free fall is also very interesting. Can you explain it to me in detail? If I'm not mistaken, it should also be related to gravity."

"I think a direct experiment can better illustrate the problem!" Lynn shrugged. Practice is the only criterion for testing the truth.

"Then according to this law, the falling speed of a feather and this dirt ball should be exactly the same!" Kevin, who had been listening to the conversation between the two and had not found a chance to interrupt, couldn't wait to speak.

He admitted that the planetary theory that the [Secret Society] came up with was indeed a school of its own, but this so-called law of falling bodies was pure nonsense!

Kevin directly activated the [Hand of the Mage] to lift up the solid earth ball on the table, and then used the same method to lift the feather pen into the air, and then directly canceled the spell, and the two at the same height fell down together.

In just two seconds, the soil ball fell heavily to the ground and broke into several pieces, while the feather pen took more than ten seconds to fall to the ground.

Seeing this result, the wizards present looked at Lin En together with sarcastic or amusement expressions on their faces.

"This is just the influence of air resistance. Why not try the experiment in a vacuum?" Lin En said calmly. During the half month of drifting in the sea of ​​fog, he had already done a simple version of the small ball experiment in advance, so he was naturally not worried about the possibility of overturning.

Vacuum? The professors at the academy pondered this new term, and after Lin En's explanation, they quickly understood its meaning...

Helram thought about it, asked everyone to step back, then slowly stretched out his hand and tapped lightly.

Lin En immediately and clearly felt that the "element" in front of him was being stripped away at a very fast speed under some inexplicable force. A moment later, a rectangular vacuum field with a length and width of four meters and a height of seven meters appeared in front of everyone.

Seeing that Helram created and maintained a large vacuum area so easily, Lin En couldn't help but feel a little surprised.

The power of a great wizard is much stronger than that of a formal wizard. Lin En tried to test him, but he didn't expect that the other party could do it so easily.

Hellram took the feather pen and used magic to create a solid iron ball, placing both of them in a vacuum at the same time.

Two objects with a weight difference of a thousand times fall at the same time.

The expressions of Theodore and others gradually changed from casual to horrified at this moment. Their eyes widened and they stared at the scene intently, because the feather pen and the solid iron ball were actually falling at the same speed.

"Really, this is actually true..." Philip muttered to himself in astonishment.

"This is impossible! Master Hellram, could it be that you accelerated the falling speed of the feather pen?" Kevin stood up suddenly, looked at Hellram, and couldn't help but ask.

These words were undoubtedly offensive, but Kevin obviously didn't care about that anymore.

Helram ignored him and continued his experiment, replacing the iron ball and feathers with other materials, such as wood, stone, water droplets... The results of the experiments were exactly the same.

Seeing this, no matter how the professors present felt, they had to admit that the law of free fall in the manuscript was the truth! "Is Master Yade's theory completely wrong?" Kevin's puzzled expression never faded from beginning to end.

"No, there is nothing wrong with his theory. It is just an interpretation of air resistance." Lynn shook his head and said freely.

The reason why Yad's theory became popular and was accepted by most wizards must be that it explained some natural phenomena.

For example, the fluid mechanics knowledge used by his teacher Kelu when improving the [Ice Blade] was an extension of Yad's theory.

When Lin En was reading "Magic Weekly", he even found that some wizards integrated air resistance into the influence of gravity, and believed that the reason why air and elements are constantly moving is also due to the effect of gravity.

This is undoubtedly a very confusing hypothesis.

However, Lynn would never laugh at or look down on the other party. The process of exploring the truth of the world is always accompanied by countless fallacies.

Whether in history or modern times, scholars from all walks of life can often propose many different hypotheses for the same physical phenomenon, each of which sounds reasonable and can explain part of the phenomenon.

Only with the passage of time and continuous verification, truth will eventually triumph over fallacy.

The reason why he can sit here and talk freely is not because he is smarter than everyone present, but simply because he is standing on the shoulders of giants...
