Lynn's words instantly detonated the audience, and even Raphael and the others, who were in charge of maintaining order in the seminar, couldn't sit still.

If in the past, Lynn's rhetoric was digging the foundations of the wizarding world, now it is trying to knock down the entire magical edifice!

"Lord Lynn, this is not the time to joke!" Raphael's expression was very serious, he looked at Lynn, and said solemnly. "Didn't the law of free fall and the theory of the orbit of the stars prove the effect of gravity?"

Raphael really doesn't understand, why the other party suddenly said such a violent statement, isn't this slapping his own face?

There are not a few people who think the same way as Raphael, and some even think that Lynn is not crazy, or deliberately say some strange things to attract their attention.

Amidst the crowd of doubts, Lynn spoke again. "In my opinion, the so-called gravitational attraction is essentially a phenomenon of space-time curvature!"

The current mainstream theory in the Wizarding Lands is that gravity affects and distorts space, but Lynn reverses cause and effect, and it is precisely because of the change in space that the phenomenon of gravity is caused!

So immediately someone stood up and asked. "If it's not gravity, what kind of force is it that deforms space?"

"Quality, of course!" Lynn said categorically. "The reason why we feel the effects of gravity or 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 the few other great wizards who specialize in force field magic looked thoughtful.

And those formal wizards feel that their brain power is a little insufficient, and Lynn's every word is constantly challenging the limits of their imagination and thinking ability!

Gravitational pull doesn't really exist, or maybe it's just a phenomenon, it's actually space pulling them in a certain direction.

This invisible and intangible spatial change is difficult for many wizards to understand, especially how the distortion of space does this.

Lynn didn't give a long explanation, but turned sideways, and on the high platform behind him was placed a round piece of cloth, made of the skin of the feathered serpent, which had a very good elasticity.

It just sat on an iron frame, crumbling tightly.

Everyone present looked at it curiously, and Lynn picked up a ten-kilogram ball and placed it in the center of the cloth.

In the next moment, the originally straight round cloth instantly recessed, with the sphere as the center, forming a curved surface, and the more the outward the curved surface, the weaker the degree of bending.

"As for the so-called gravitational pull, it's like this!"

Lynn took out a one-kilogram ball from his pocket, casually pressed it against a corner of the curved surface, and then let go of his hand.

Everyone in the seminar had their eyes widened, and the wizards in the back row stood up, and some even directly used farsightedness magic just to see more clearly.

Without Lynn applying additional force, the ball automatically rolls down the center of the curved surface.

"I see, gravity ...... That's gravity! A great wizard was so excited that he imagined a three-dimensional cloth, and then collapsed in all directions towards the center, drawing the object in.

Without waiting for everyone to recover, Lynn picked up another ball again, changed the angle to exert a little force, gave it an initial velocity, and the ball changed its way of motion, no longer rolling straight down, but rotating along the curved surface, around the large round ball in the center.

"Star orbit, this is star orbit!" Another person shouted excitedly.

All the wizards' eyes were focused on this white round cloth, which was no more than a meter in diameter, and they vaguely felt that they were staring at not a few spheres, but a great picture of the stars of the universe!

With the help of a piece of elastic leather, Lynn intuitively shows the distortion and collapse of three-dimensional space in the form of two-dimensional curved surfaces!

However, the distortion of time cannot be presented in such an intuitive way.

Fortunately, this little experiment is only to help these wizards better understand the phenomenon of spatial bending and attraction.

Lynn looked at the group of wizards in the seminar who were 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 space-time how to bend, and space-time tells matter how to move...... The wizards in the hall who knew a little about force field magic were constantly chewing on these words.

Wonderful, so subtle!

This is the mystery of space-time magic!

"Lord Lynn, your speech today alone is enough to be nominated for a Corona Medal!" One of the great wizards in charge of maintaining order in the venue looked at Lynn's slightly immature face and sighed.

At the last seminar, the legendary wizard Haroff threatened to award Lynn the Corona Medal, and he was still a little resentful, the other party did propose a set of star pictures that contradicted the mainstream doctrine, not to the extent of issuing the Corona Medal, a Silver Moon Medal is enough!

But now it seems that although Lynn is only a formal wizard, his understanding of gravity and space is far from being comparable to his own.

Every word spoken today can be used as the foundation of space magic, and some fanatics have recorded Lynn's description of matter and space-time in its original form, even if they can't understand it, they can always be used when talking about it in the future.

"I have one more question...... Why doesn't the planet beneath our feet rush towards the sun under the influence of gravity? It's like that little ball. Raphael asked, puzzled.

The second ball that Lynn put down, although it continued to rotate around the curved surface as it fell, its amplitude became smaller and smaller, and it would eventually be sucked into the side of the large ball.

"That's because there is no air resistance in the vacuum, the speed of the stars does not slow down, it forms a balance with gravity, and of course it does not fall into the sun." Lynn explained.

Raphael thought for a moment, and then noticed that the ball was gradually slowing down, so it gradually moved closer to the center, and the orbit became shorter and shorter, and finally fell into the center of the curved surface.

It turned out to be so!

Raphael suddenly realized that many of his previous doubts about the orbit of the stars were solved in an instant.
