Chapter 158 Lynn's violent theory, does gravity not exist?
Darkness?
Raphael and the others paused, and then felt that all the light in the hall had disappeared, leaving only a little light from the skylight on the roof shining on the high platform.
Everyone's eyes naturally focused together, and Lynn's figure soon appeared in front of everyone, with a faint smile on his face. "Ladies and gentlemen, you are welcome to take the time to attend today's magic seminar."
The seminar hall, which seemed a little noisy at first, immediately became as noisy as a festival scene, with various discussions, and some people shouted loudly.
"Your Excellency Lynn, 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. What do cube, square and root 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 Lynn, did you use some kind of special magic to weigh the planet when you said earlier? Or is it the same division method as measuring the circumference?"
All kinds of 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 counting is not too difficult for a wizard with an easy-to-use brain, each wizard has a different degree of mastery, and the data of a planet is really too big, but in the calculation process As long as it is a little bit wrong, the final result will be very different.
So after two days of fermentation, thousands of wizards just calculated several different answers. In order to argue about right and wrong, they almost fought on the spot.
"Silence...Silence! This is not the time to ask questions yet!" A great wizard who presided over the seminar violently slapped the table, which temporarily stopped the entire louder discussion.
Lin En spoke at this time. "As for your questions, I'll answer them one by one."
"First of all, the planet under our feet has a radius of about 6875 kilometers and a volume of 1361.4 billion cubic kilometers. It can be calculated by using the circumference formula. The radius is equal to the circumference. Divide by twice the pi, and the volume can be directly calculated by substituting the radius into the formula..."
Lynn patiently explained the radius, volume, and the corresponding formulas and derivation process of the Mathematical Olympiad. After all, these are the data that must be used in subsequent experiments.
Those wizards who calculated the data accurately were naturally full of ambition, as for those who made mistakes, they showed embarrassment, and some unconvinced wizards checked the calculations on the spot.
However, there were quite a few wizards on the field like Rohr who were average in counting, and they secretly memorized these statistics in their hearts.
You must know that recently, planets and stellar orbits are the most popular topics in Greenriel, and it is inevitable to say a few words at any gathering among wizards, which seems to have become a trend.
"As for the weight of the planet under our feet and the method of measuring it? I think there is still an important problem to be solved before it can be truly deciphered!" Lynn's face straightened, and he looked at the wizards in the seminar hall, Suddenly asked.
"What do you think is the essence of gravity? Or in other words, what factors determine the weight of an object when it is weighed?"
Lin En's question stumped the wizards on the field in an instant. It looked simple but very tricky, and even a little inexplicable, like asking them to explain why water is called water instead of soil!
Of course, the weight of an object is measured with balance scales and weights. The wizards of the Alchemy Association even created a magic scale, which 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 while, a person in front of the high platform The great wizard responded.
"Yes, but no!" Lynn nodded, then shook his head again. "Gravity is a component of gravity. It is not always a constant value. Even on the same planet, the gravity felt in different places will be different..."
"In general, the closer you are to this planet, the greater the influence of gravity, and the farther you are, the smaller the influence of gravity is. Once you enter the boundless starry sky, the concept of weight will no longer exist!" Lynn explained.
"That is to say, where there is no gravity, everything has no weight?" The witch sitting in the front row couldn't help standing up. "This... is incredible!"
Although the concept of gravity has been proposed long ago, after the baptism of free fall experiments, the relationship between gravity and gravity is almost equal, but the weight of an object will change with the strength of gravity. Even disappearing is far beyond everyone's imagination.
This is simply challenging their three views!
After a while, another wizard stood up and retorted. "Your Excellency Lynn, please forgive me for not agreeing with this idea. Doesn't that mean that no matter whether it is soil or gold, silver, copper and iron, once they leave the influence of gravity, they will have no difference and become lighter than a feather ?"
"Of course they are different, because the two have different masses! And the weight we feel is actually the product of the object's mass and the acceleration of gravity!" Lynn said freely.
"Quality, what is that?" The witch who just stood up had a puzzled look on her face.
"You can understand it as the total amount of elements contained in an object!" Lynn said as concisely as possible. "It is the most basic property inherent in matter itself, and it will not change with the temperature, pressure, and speed of the outside world... Whether it is placed on a planet or in the universe, this value is the same!"
The discussion in the hall became fierce again, and the discussion was about the new concept proposed by Lynn, using mass instead of weight.
Everything in the world is made of elements, which is common sense in the wizarding land, so Lynn's words are not too difficult to understand.
However, what the other party said next stunned everyone present.
"Also, in my opinion, gravity may not exist!" Lin En didn't care whether these wizards could accept it or not, and the moment he opened his mouth, he exploded!
The scene of the seminar exploded immediately. Thousands of wizards stood up together and looked at Lin En in disbelief—he was actually denying the existence of gravity!
How dare he? !
