I Created Scientific Magic-Chapter 170 - 157 Lynn’s Outrageous Theory: Does Gravity Not Exist? (Please Subscribe)

Darkness?

Rafael and the others paused for a moment, and then realized that all the light in the hall had disappeared, leaving only the skylight in the roof that let through a hint of light, casting down onto the stage.

Everyone’s gaze naturally focused together, and Lynn’s figure soon appeared before them, a faint smile on his face. "Ladies and gentlemen, welcome to today’s magic seminar."

The hall, already somewhat noisy, immediately became as loud as a festival celebration; a variety of comments could be heard, and some even shouted out loud.

"Lynn, regarding your method of measuring the central angle of the Earth’s core, there are a few points I still don’t understand, and what exactly do ’cube,’ ’square’ and ’root’ mean?"

"What exactly is the radius and volume of the planet beneath our feet? Is it eight hundred and sixty billion cubic kilometers or one trillion two hundred and thirty billion cubic kilometers?"

"Wizard Lynn, when you previously talked about weighing the planet, did you use some special magic? Or is it the same divisional method as used in measuring circumference?"

A variety of questions came one after another; aside from those wizards who were curious about the method of weighing, some wanted to confirm whether the numbers they had calculated were correct.

Although math isn’t too difficult for a wizard with a good brain, the proficiency of each wizard is different. Furthermore, the various data points of a planet are so enormous that a slight error in the calculation process can lead to a vastly different result.

So, after two days of fermenting, thousands of wizards managed to calculate several different answers, and to argue about right and wrong, they almost came to blows on the spot.

"Silence... Silence! Now is not the time for questions!" the grand wizard hosting the seminar banged on the table, irritable, finally making the increasingly loud discussion halt for a moment.

Only then did Lynn speak. "Regarding these questions of yours, let me answer them one by one."

"First of all, the planet beneath our feet has a radius of approximately six thousand eight hundred and seventy-five kilometers, and a volume of one trillion three hundred and sixty-one billion four hundred million cubic kilometers. By using the circumference formula to calculate backwards, the radius is equal to the circumference divided by twice the value of pi, and the volume can be directly calculated by substituting the radius into the formula..."

Lynn patiently explained the radius, volume, and the corresponding mathematical formulas and derivation processes, as all these data were necessary for the upcoming experiments.

Those wizards who had precisely calculated the data naturally felt smug and satisfied, whereas those who had miscalculated appeared embarrassed, and some who didn’t agree even began to recheck the calculations on the spot.

However, there were also quite a few wizards like Luo’er in the audience, those with average mathematical skills, who quietly committed these data to memory.

You see, in recent times, the topics of planets and stellar orbits have been the hottest subjects in Greenidyre, such that they inevitably come up in any gathering of wizards and have become quite the trend.

"As for the weight of the planet beneath our feet and the method of measuring it, what is it? I think before we truly unravel this, there is one important question we need to answer!" Lynn’s expression became serious as he looked towards the wizards in the seminar hall and suddenly asked.

"What do you think is the nature of gravity? Or rather, what factors do you believe determine the weight of an object when being weighed?"

Lynn’s question immediately stumped the wizards present; it seemed simple yet was puzzling, even somewhat inexplicable. It was like asking them why water was called water and not earth!

Of course, the weight of something is measured using a balance scale and weights, and the wizards at the Alchemy Association even created magic scales that can measure an object’s weight very accurately.

"What you are trying to say is that the gravity we feel is the gravitational force possessed by the planet itself, right? So, is it because of the influence of gravity that we can measure an object’s weight?" After pondering for a long while, a grand wizard in front of the stage responded.

"Yes, but also no!" Lynn nodded, then shook his head. "Gravity is a component force of universal gravitation; it is not always a constant value. Even on the same planet, the gravity felt in different places varies…"

"In general, the closer you are to the planet, the greater the effect of universal gravitation, and the further away, the lesser the effect. Once you enter the boundless cosmos, the concept of weight ceases to exist!" Lynn explained.

"So you’re saying that in a place without gravity, everything is weightless?" A female wizard in the front row couldn’t help but stand up. "This… is unbelievable!"

Although the concept of gravity had been put forth long ago, and its relationship with gravity almost equaled through the trials of freefall experiments, the idea that the weight of an object could change with the strength of gravity, and even disappear, was still far beyond everyone’s imagination.

This was truly challenging their worldviews!

Shortly, another wizard stood up and countered, "Excuse me, Wizard Lynn, but I cannot agree with this concept. Wouldn’t that mean, whether it’s soil or gold, silver, copper, iron, once they leave the influence of gravity, they would all be indistinguishable, and become lighter than feathers?"

"They are certainly different because they have different masses! And the weight we feel is actually the product of the object’s mass and gravitational acceleration!" Lynn said with ease.

"Mass, what is that?" the female wizard who had just stood up looked puzzled.

"You can understand it as the total amount of elements contained within an object!" Lynn stated as succinctly as possible. "It is the most fundamental property inherent to the material itself, and does not change with the external temperature, pressure, speed… Whether placed on a planet or in the universe, the value remains the same!"

The discussion in the hall intensified, this time about Lynn’s new concept of using mass to replace weight.

Everything in the world is composed of elements; in Wizard Land, this is common knowledge. Therefore, Lynn’s words were not too hard to comprehend.

However, what he said next stunned everyone present.

"Furthermore, in my view, gravity may not even exist!" Lynn, not caring whether these wizards could accept it or not, opened with a bombshell!

The seminar hall instantly erupted, with thousands of wizards standing up in disbelief, staring at Lynn—he was actually denying the existence of gravity!

How could he dare?!
