Seeing that Lynn was 'speechless' under Harrov's questioning, he could only excuse himself by not knowing.

The wizards of the Prophecy School, who had been dead-faced, suddenly stood up again, and Yolande questioned as if he had found some breakthrough.

"Mr. Lynn, if I'm not mistaken, you're not a great wizard yet, and you can't use force field magic, right?"

Yoland's problem was very fatal, and it immediately caused many wizards who supported Lynn to discover a serious problem.

Since the other party is not a great wizard and can't even do force field magic, how did he explore this gravitational formula.

"The formula for gravitation is based on the laws of the movement of the three stars proposed by the legendary wizard Kepler, and then calculated by the Olympiad." Lynn replied with a comfortable look on his face, and repeated the three laws.

Last night, he used this method to confirm that the law of gravitation still applies in this other world, so he was very calm in the face of Yoland's inquiry.

"Extrapolation? How to calculate? Another prophetic witch jumped out at once. According to you, to calculate gravitational force, you need to know the so-called gravitational constant, the distance between two stars, and their mass. ”

"A star is incomparably huge, tens of millions of times larger than Mount Kogar, the largest in the wizarding lands, and the distance between them is unimaginably far, how can this be measured, is it difficult to measure it with a ruler? Or will we not be able to weigh the continent under our feet on the scale? ”

"If that's the case, then what should be placed on the other side of the scale, is it another star?" The witch sneered.

In the hall of the discussion venue, thousands of wizards had a heated discussion.

Because the picture of the stars that Lynn had shown them was so perfect, many people were willing to believe that Lynn's gravitational formula was true.

But no matter how much they meditated, they could not think of any way to calculate the weight and distance of the stars.

Raphael looked at Lynn and sighed, he suspected that this formula of gravitation was probably a purely theoretical doctrine that had not been proven.

Originally, there was nothing to do, after all, there were many purely theoretical doctrines, and this one was not bad, but it attracted the attention of Lord Harrov, and even to the point of issuing the Corona Medal.

If this theory turns out to be wrong in the end, then how much praise Lynn has received before, how badly it will fall.

Yolande and the others breathed a sigh of relief, they had reason to believe that the so-called gravitation formula of the other party was simply made up!

Lynn's eyes were full of pity as he looked at the others, as if he were looking at a fool......

"Don't think too hard about this process, ladies and gentlemen, with some basic knowledge of the Olympiad, even a few of my apprentices can calculate the mass of a star and the distance between them."

Lynn said in a flat tone, but in the eyes of the wizards of the prophecy school, this is nonsense, if Lynn has a way to calculate it, they may still believe a point or two, but if even a wizard apprentice can calculate the data of the stars, it can only be described as outrageous.

The eyes of thousands of wizards immediately turned to Jonny, Lydia, Elok, and Peirce......

I'm not, I don't, I can't figure it out!

Alok was about to cry, he had already discovered that Professor Lynn might have had some kind of unrealistic illusion about their abilities.

Actually, they really aren't that awesome!

Such a huge number of stars, how heavy they are, how far away they are from each other, how can you figure it out!

Lynn didn't seem to see the resentful gaze of Elok and the others, and continued to speak. "If you want to measure the distance between the stars, you need to find a reference object in the vast universe, and the best reference object is the planet under our feet! Just know its data, and that's all it takes! ”

Yolande sneered, he wanted to see how the other party was going to calculate the data of the continent under his feet.

Lynn looked at Elok and asked suddenly. "If I want to know the circumference of a circle, what should I do?"

"You can multiply the diameter by pi, Professor!" Lydia shouted loudly, she still remembered this very well.

"What if I don't know the diameter data?" Lynn asked again.

Lydia's little face froze immediately, and Eloke and Peirce pondered for a while, and finally Jonny pointed to the sand table placed on the high platform and responded.

"A circle has three hundred and sixty scales, and each scale is equal, so I can also judge its circumference by measuring the length of each tick segment!"

"That's good, Jonny, you've been learning the Olympiad very well." Lynn laughed, then continued. "The planet under our feet, it happens to be a circle, can't it be calculated by using the same method?"

As soon as these words came out, the wizards in the hall couldn't help but be stunned for a moment, as if this was the case.

"The planet under our feet is incomparably huge, how can we judge the angle and distance?" Harrov frowned, he had flown to an altitude of tens of thousands of meters, and with the help of magical sight, he could see a slight arc, and it was impossible to artificially divide the scale by equal amounts like the sand table under his feet.

Lynn didn't answer directly, walked to the sand table, and asked. "I've heard that every year in mid-July, under the midday sun, the shadow of the Corona Tower overlaps with the body of the tower, right?"

"Not bad!" Raphael nodded.

"Then I believe that you should not have forgotten that when I introduced the changes of the four seasons before, the direct point of the sun, the reason why the tower of the corona has no shadow is precisely because we are at the direct point of the sun at noon in mid-July!"

"Let's make it a zero scale!" Lynn walked over to the sand table, took a stick, and placed it in the sand table where the zero scale was placed, and then put down a second stick a little further away.

"Then we just need to erect a towering pillar there as far away as possible from the Corona Tower, and measure the length of the column and the shadow respectively, so that we can calculate the angle between the center of the earth?"

"Take the towering pillar as the base point, and use the sun as a ruler...... Genius, what a genius idea! Harrov said excitedly, so that the column is like a straight line on the arc, then the shadow is the other side of the right angle, this is a simple right triangle to find the angle of the top angle!

Raphael and the others looked at the two wooden roots placed on the sand table, and couldn't help but gasp, how can it still be like this?
