dark?

Raphael and others paused for a moment, and then they felt that all the light in the hall disappeared, leaving only a little light from the skylight on the roof, shining on the high platform.

Everyone's eyes naturally focused together, and Lin En's figure soon appeared in front of everyone, with a slight smile on his face. "Ladies and gentlemen, you are welcome to take the time to participate in today's magic seminar.

meeting."

The seminar hall, which was originally a bit noisy, immediately became as noisy as a festival celebration, with all kinds of discussions and some people even shouting loudly.

"Sir Lin En, there are still a few things I don't understand about the method you proposed to calculate the angle between the center of the earth. In addition, what exactly do cubes, squares and square roots mean?"

"What is the radius and volume of the planet under our feet? Is it 860 billion cubic kilometers or 1230 billion cubic kilometers?"

"Your Excellency Linn, when you mentioned weighing the planet before, did you use some special magic? Or was it the same division method as measuring the circumference?"

Various questions came one after another. In addition to those wizards who were curious about the weighing method, there were also some wizards who wanted to confirm whether the values ​​they calculated were correct.

Although calculations are not difficult for wizards with good brains, each wizard has different levels of mastery. In addition, the various data of a planet are really too large. In the process of calculation,

Just a small mistake can make a huge difference in the final result.

So after two days of fermentation, thousands of wizards calculated several different answers, and almost got into a fight on the spot in order to argue about right and wrong.

"Silence...Silence! It's not the time for questions yet!" A great wizard who was presiding over the seminar pounded the table angrily, which temporarily stopped the growing discussion.

Only then did Lin speak up. "As for your questions, I'd better answer them one by one."

"First of all, the radius of the planet under our feet is about 6875 kilometers, and the volume is 1361.4 billion cubic kilometers. We can calculate it by using the circumference formula. The radius is equal to the circumference.

Divide by twice the pi ratio, and the volume can be calculated directly by substituting the radius into the formula..."

Lin En very patiently explained the radius, volume, and the corresponding Olympian formulas and derivation process. After all, these are all data that must be used in subsequent experiments.

Those wizards who accurately calculated the data were naturally satisfied, while those who made mistakes looked embarrassed, and even some unconvinced wizards started checking the calculations on the spot.

However, there are also many wizards like Rohr on the field who have average calculation skills and secretly keep these data in their hearts.

You must know that in recent times, planets and stellar orbits have been the hottest topics in Greenrial. Any gathering among wizards cannot help but say a few words. It has become a trend.

"As for the weight of the planet under our feet and the method of measuring it? I think there is an important issue that needs to be solved before we can truly decipher it!" Linn's face straightened and he looked at the wizards in the seminar hall.

Suddenly he asked.

"What do you think is the nature of gravity? Or what are the factors that determine the weight of an object when it is weighed?"

Linn's question instantly stumped the wizards on the field. It seemed simple but very tricky, even a little incomprehensible, as if he was asking them to explain why water is called water and not soil!

Of course, the weight of an object is measured using a balance scale and weights. The wizards of the Alchemy Association even made a magic scale that can weigh an object very accurately.

"What you want to say is that the gravity we feel is the gravity of the planet itself, right? So, it is because of the influence of gravity that we can weigh an object?" After pondering for a long time, a person in front of the platform said

The great wizard responded.

"Yes, but no!" Linn nodded, and then shook his head. "Gravity is a component of universal gravitation. It is not always a constant value, even on the same planet but in different places.

The gravity you feel will also be different..."

"Generally speaking, the closer to the planet, the greater the influence of gravity, and the further away, the smaller the influence of gravity. Once you enter the boundless starry sky, the concept of weight no longer exists!" Linn explained.

"In other words, in a place without gravity, everything is weightless?" The witch sitting in the front row couldn't help but stand up. "This... is incredible!"

Although the concept of gravity has long been proposed, after the baptism of free fall experiments, the relationship between gravity and gravity is almost equal, but the weight of an object will change as the strength of gravity changes.

Even disappearing is far beyond everyone's imagination.

This is simply challenging their three concepts!

After a while, another wizard stood up and retorted. "Your Excellency Linn, please forgive me for not agreeing with this concept. Doesn't that mean that whether it is soil or gold, silver, copper, and iron, once it leaves, the influence of gravity will

, they won’t have any difference and will become lighter than feathers?”

"Of course they are different, because they have different masses! And the weight we feel is actually the product of the object's mass and the acceleration of gravity!" Lin En said freely.

"Quality, what is that?" The witch who had just stood up had a puzzled look on her face.

"You can understand it as the total amount of elements contained inside an object!" Linn said as concisely as possible. "It is the most basic attribute inherent in the substance itself, and does not change with the temperature of the outside world.

It changes due to pressure and speed... Whether it is placed on a planet or in the universe, the value is the same!"

The discussion in the hall became intense again, and what was being discussed was the new concept proposed by Lin En, using mass to replace weight.

Everything in the world is composed of elements. This is common knowledge in the wizarding land, so Linn's words are not too difficult to understand.

However, what the other party said next shocked everyone present.

"In addition, in my opinion, gravity may not exist!" Linn didn't care whether these wizards could accept it or not, and he burst out with it as soon as he opened his mouth!

The seminar site immediately exploded. Thousands of wizards stood up and looked at Linn in disbelief - he was actually denying the existence of gravity!

How dare he?!
