Lin En's words instantly detonated the entire audience, and even Raphael and others who were responsible for maintaining the order of the seminar could not sit still.
If Lynn's remarks in the past were trying to undermine the foundation of the magic world, now he is trying to knock down the entire magic building!
"Your Excellency Linn, now is not the time to joke!" Raphael's expression was very serious, he looked at Linn and said solemnly. "Don't the laws of free fall and the theory of star orbits you proposed before prove the influence of gravity?"
Raphael really didn't understand why the other party suddenly said such violent remarks. Wasn't this a slap in his face?
There are not a few people who have the same idea as Raphael. Some people even think that Linn is probably crazy, or that he deliberately tells some strange stories to attract their attention.
Amidst all the doubts, Linn spoke again. "In my opinion, the so-called gravity is essentially a phenomenon of curvature of space and time!"
The current mainstream theory in the wizarding land is that gravity affects and distorts space, but Linn reversed the cause and effect. It is precisely because of the changes in space that the gravitational phenomenon is caused!
So someone immediately stood up and asked. “If it’s not gravity, what kind of force deforms space?”
"Of course it's quality!" Lin En said decisively. "The reason why we feel gravity or the influence of gravity is precisely because the huge mass of the planet under our feet distorts time and space, forcing us to fall towards the center of the earth..."
Harrov and a few great wizards specializing in force field magic looked thoughtful.
Those official wizards felt that their brain power was not enough. Every word Lin En said was constantly challenging the limits of their imagination and thinking abilities!
Gravity does not actually exist, or it is just a phenomenon. In fact, space is pulling them in a certain direction.
This invisible and intangible change in space makes it difficult for many wizards to understand, especially how they can't imagine how the distortion of space achieves this.
Lin En did not give a long explanation, but turned sideways. There was a round piece of cloth placed on the high platform behind. It was made from the outer skin of the feathered snake and had very good elasticity.
It was placed on an iron frame and collapsed tightly.
Everyone present looked over curiously, and Lin En picked up a ten-kilogram ball and placed it in the center of the round cloth.
The next moment, the originally straight round cloth dented in an instant, forming a curved surface with the ball as the center. The curved surface became weaker as it went outward.
"As for the so-called gravity, it's like this!"
Linn took out a one-kilogram ball from his pocket, casually pressed it on a corner of the curved surface, and then let go of his hand.
Everyone in the seminar stared wide-eyed, and the wizards in the back row stood up. Some even used far-sighted magic to see more clearly.
Without Linn exerting any additional force, the ball automatically rolled down toward the center along the curve of the curved surface.
"So that's it, gravity...this is gravity!" A great wizard couldn't contain his excitement. He imagined a three-dimensional cloth, and then the four sides collapsed toward the center, attracting objects.
Lin En didn't wait for everyone to calm down, then picked up another small ball again, changed the angle and exerted a little force, giving it an initial speed, and the small ball changed its movement mode and no longer rolled straight down. , but keeps rotating around the big ball in the center along the curved surface.
"Star orbit, this is star orbit!" Another person shouted excitedly.
All the wizards' eyes were focused on this piece of white circular cloth with a diameter of only one meter. They vaguely felt that they were not staring at a few balls, but the great picture of the stars in the universe!
Lin very intuitively used a piece of elastic leather to show the distortion and collapse of the three-dimensional space in the form of a two-dimensional curved surface!
However, the distortion of time cannot be presented in this intuitive way.
Fortunately, this is enough. This small experiment is just to help these wizards better understand the phenomenon of attraction caused by space curvature.
Lin En looked at the excited, absent-minded, excited, or enthusiastic wizards in the seminar, and concluded again.
"So I think gravity is a geometric effect caused by the curvature of space and time. Matter will tell space and time how to bend, and space and time will tell matter how to move!"
Matter tells time and space how to bend, and time and space tells matter how to move... The wizards in the hall who had some knowledge of force field magic were all chewing on these words.
Exquisite, so exquisite!
This is the secret of time and space magic!
"Your Excellency Lin En, your speech today alone is enough to be nominated for a Corona Medal!" A great wizard responsible for maintaining order at the venue looked at Lin En's slightly immature face and sighed.
In the last seminar, the legendary wizard Harrov threatened to award Linn with the Corona Medal. He was still a little dissatisfied. The other party did propose a set of star pictures that went against the mainstream theory, and it would not be enough to award Linn with the Corona Medal. As for the level of medals, a Silver Moon Medal is enough!
But now it seems that although Linn is only an official wizard, his understanding of gravity and space is far beyond his own.
Every sentence spoken today can be regarded as the foundation theory of space magic. Some fanatics even recorded Linn's description of matter and space-time exactly. Even if they don't understand it, they will always brag about it when talking to others in the future. Can be used.
"I have another question... Why doesn't the planet under our feet rush towards the sun under the influence of gravity? Just like that small ball." Raphael asked in confusion.
The second small ball that Lin put down continued to rotate around the curved surface as it fell, but the amplitude became smaller and smaller, and it would eventually be sucked into the big ball.
"That's because there is no air resistance in a vacuum. The stars will not slow down and form a balance with gravity. Of course, they will not fall into the sun." Lin En explained.
Raphael thought for a while and then noticed that the previous small ball was gradually moving closer to the center because its speed was gradually slowing down. The trajectory became shorter and shorter, and finally fell into the center of the curved surface.
It turns out to be like this!
Raphael suddenly realized that many of his previous doubts about the orbits of the stars were instantly solved.
