Chapter 159 Matter tells space-time how to bend, and space-time tells matter how to move
Lin En's words instantly detonated the audience, and even Raphael and others who were in charge of maintaining the order of the seminar couldn't sit still.
If Lynn's remarks in the past were digging the foundations of the magic world, now they are trying to kick down the entire magic building!
"Your Excellency Lynn, now is not the time to joke!" Raphael looked at Lynn with a serious expression and said solemnly. "The law of free fall and the theory of star orbits that you proposed before, don't both prove the influence of gravity?"
Raphael really doesn't understand why the other party suddenly utters such violent remarks. Isn't this slapping yourself in the face?
There are not a few people who have the same idea as Raphael. Some even think that Lynn is crazy, or deliberately say some anecdotes to attract their attention.
Amidst the doubts, Lynn spoke again. "In my opinion, the so-called gravity is essentially a phenomenon of space-time curvature!"
The existing mainstream theory in the Land of Wizards is that gravity affects and distorts the space, but Lin En reverses the cause and effect, and it is precisely because of the change in the space that the gravitational phenomenon is caused!
So someone immediately stood up and questioned. "If it is not the effect of gravity, then what kind of force deforms the space?"
"Of course it's quality!" Lynn said firmly. "The reason why we feel gravity or the impact of gravity is precisely because of the huge mass of the planet under our feet, which distorts time and space and forces us to fall towards the center of the earth..."
Haroff and a few great wizards who specialize in force field magic looked thoughtful.
And those official wizards feel that their brain power is not enough, and every word of Lynn is constantly challenging the limit of their imagination and thinking ability!
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 space change makes many wizards find it difficult to understand, especially how the distortion of space can achieve this.
Lin En didn't give a long explanation, but turned his body sideways. On the high platform behind was a round piece of cloth, which was made of feathered snake skin and had very good elasticity.
It was just placed on an iron frame, and it was collapsed tightly.
Everyone present looked over curiously, and Lynn picked up a ten-kilogram ball and placed it in the center of the round cloth.
The next moment, the originally straight round cloth was dented in an instant, forming a curved surface with the ball as the center, and the degree of curvature became weaker as it went outward.
"As for the so-called gravity is like this!"
Lin En 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 directly.
Everyone in the seminar stared wide-eyed, and the wizards in the back row even stood up, and some of them even used farsightedness magic directly, just to see more clearly.
Without Lynn exerting any additional force, the ball automatically rolled down toward the center along the curvature 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 collapsed in all directions towards the center, attracting objects.
Lin En didn't wait for everyone to slow down, he picked up another small ball again, changed the angle and exerted some strength, and gave it an initial speed, the small ball changed its movement mode and stopped rolling straight down , but along the curved surface, constantly rotating around the big central ball.
"Star track, this is star track!" Another person shouted excitedly.
All the wizards focused their eyes on this piece of white cloth with a diameter of less than one meter. They vaguely felt that what they were staring at was not a few balls, but a great picture of the stars in the universe!
Lin En very intuitively uses a piece of elastic leather to show the distortion and collapse of the three-dimensional space in the form of a two-dimensional surface!
But the distortion about 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 space curvature producing attraction.
Lin En looked at the group of wizards in the seminar who were either excited, distracted, excited, or fanatical, and concluded again.
"So I think gravity is a geometric effect caused by the curvature of space-time. Matter will tell space-time how to bend, and space-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 have a little understanding of force field magic are constantly chewing on these words.
Subtlety, really sublime!
This is the mystery of space-time magic!
"Your Excellency Lynn, your speech today alone is enough to be nominated for a Corona Medal!" A great wizard responsible for maintaining order in the venue looked at Lynn's slightly immature face and said with a sigh.
At the last symposium, the legendary wizard Harov threatened to award Lynn the Corona Medal. He was still a little upset. The other party did indeed propose a set of star images that were contrary to the mainstream theory, and it would not be possible to issue the Corona The level of the medal, a silver moon medal is enough!
But now it seems that although Lynn is only an official wizard, his understanding of gravity and space is far from what he can match.
Every word uttered today can be used as the foundational theory of space magic. Some fanatics have even recorded Lin En's description of matter and time and space. can be used.
"I have another question... Why doesn't the planet under our feet rush towards the sun under the action of gravity? Just like that little ball." Raphael asked in puzzlement.
The second small ball that Lynn put down, while falling, continued to rotate around the curved surface, but the range was getting smaller and smaller, and it would eventually be sucked into the big ball.
"That's because there is no air resistance in the vacuum, and the speed of the stars will not slow down, forming a balance with gravity, and of course they will not fall into the sun." Lynn explained.
Raphael thought for a while, and then he noticed that the previous small ball gradually moved 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 turned out to be like this!
Raphael suddenly realized that many doubts about the orbits of the stars were solved in an instant.
