I Created Scientific Magic-Chapter 172 - 159: Mirror Reflection Measurement of Gravitational Constant

After Rafael settled down contentedly, another master wizard skilled in Force Field Magic curiously asked.

"Master Lynn, since you said that it’s mass that causes the distortion of space, which in turn causes the phenomenon of gravity, does that mean only celestial bodies with large mass possess this characteristic?"

"This point, I believe Lord Harrov’s theory about gravity clarifies that this phenomenon exists widely among all things," Lynn replied composedly.

"Does that include a grain of sand, a stone as well?" Lydia raised her hand high and asked a question that puzzled most of those present.

"Of course!" Lynn nodded and began to explain, "It’s like putting an object into water, even a fine grain of sand inevitably displaces the water."

"Then why have we never felt this so-called... attraction brought about by space distortion?" Luo’er couldn’t help but stand up, a question that he found most perplexing.

If gravity existed in any object, then logically, it should also exist in them. Why then, when walking on the road, aren’t the sands and stones pulled toward them?

"That’s because, compared to our mass, their impact on space-time is too minuscule to notice; even in front of a towering mountain, its disturbance of space-time could almost be ignored, and its attraction is probably far less than that of a beautiful lady passing by!" Lynn said jokingly.

In the four fundamental forces, although the range of gravity’s influence is theoretically infinite, it is the weakest force in terms of effect.

This peculiar analogy made Luo’er somewhat bittersweet, but he still posed another vital question, "Since the influence of gravity is extremely weak, how do we confirm that it exists in everything?"

Only a grand wizard could barely sense the subtle changes in space curvature; as for regular wizards, understanding space-time could only be wholly reliant on imagination.

"Master Luo’er, in fact, that is exactly the topic we need to discuss today!" said Lynn as he clapped his hands; instantly, Johnny, Ailoke, and others brought forward a very sophisticated experimental device.

It resembled a beam balance used for weighing heavy objects, but at the top, it was tied with a two-meter-long steel wire, allowing it to suspend in mid-air, with a one-kilogram spherical weight at each end of the swing arm.

Are they preparing for a weighing? The wizards in the audience were baffled but soon dismissed this conjecture as Lynn had Johnny and others move two fifty-kilogram iron spheres next to the small spheres.

Then Lynn began to explain, "As I mentioned earlier, gravity exists in every object, always attracting each other, though very weak, it’s not non-existent. It just requires some special means to visualize this disturbance."

"I think you might still remember our previous pendulum experiment, where utilizing a thin, long steel wire could magnify minute disturbances significantly. This torsion balance device also employs a similar method, which I call the Minute Deformation Amplification Method!"

According to the law of universal gravitation, the large spheres will exert gravitational pull on the small spheres, causing the whole T-shaped torsion balance to rotate towards the direction of the large spheres. The greater the gravitational force, the larger the angle of rotation.

Conversely, by measuring the angle of rotation of the steel wire, the force exerted on both ends of the swing arm can also be calculated.

With Lynn’s explanation, the assembly of wizards found this compact and exquisite apparatus fascinating, observing it intently.

"Do you see anything? Pearce?" Ailoke stared hard at the small sphere hanging on the swing arm, unable to detect any disturbance after a long time, and involuntarily turned to his companion, whispering.

"Of course, just as the professor said, the small spheres are continually being pulled closer under the gravitational influence of the large spheres..." Pearce nodded, pretending to understand, and continued to watch the torsion balance on the stage intently. But, like Ailoke, his eyes grew tired, and he could not perceive any change either.

But since the professor said this method works, it certainly must be correct!

The wizards in the hall were also staring at those spheres, except for a few like Harrov and Rafael who could see the slight rotation of the suspended steel cables, the rest were completely baffled. One of the wizards couldn’t help but stand up and asked directly.

"Master Lynn, has your experiment started yet?"

Lynn nodded and casually responded, "Just wait another minute, and you’ll be able to see clearly!"

Seeing Lynn’s certainty, the somewhat impatient wizards could only continue to wait.

The hand of the magic clock soon passed twelve!

The Sun was already high above, and its rays beamed directly downward.

At that moment, Lynn picked up an unusually small glass mirror and reflected the sunlight coming straight through the skylight onto the slender steel wire.

Only then did many wizards notice that a strange circular mirror was also hanging in the middle of the steel wire. After the sunlight hit the center of the circular mirror, it was reflected again onto the opposite scale.

"I see it, it’s moving, the light spot is moving!" Lydia exclaimed loudly.

Indeed, there was no need for Lydia to remind them, as this time everyone could see very clearly. The light spot reflected on the scale was moving slowly to the right, gradually shifting from zero to one division.

"Could this be the influence of the Earth’s rotation?" a witch suddenly interrupted with a killjoy remark.

Luo’er and others also immediately thought of this possibility.

Yes, could it be possible that the Earth’s rotational force was affecting the slow movement of the sphere, just like the pendulum before?

Lynn did not respond but instead moved the large sphere, which was originally on the right side of the small ball, to the left side. Moments later, the light spot changed direction and began to shift to the left, slowly moving back to zero on the scale.

Seeing this incredibly magical scene, everyone’s hearts were devoid of any doubts, leaving only astonishment!

Even the most critical and skeptical could not deny the existence of gravity.

After all, the light spot was not moving randomly, but shifted according to the position where the large sphere was placed.

So undoubtedly, this was the effect of gravity!

It was the attractive force produced by the distortion of space!

Compared to the other wizards who were still marveling at the theory of universal gravitation, Harrov was more focused on the intricacy of the experiment itself.

A fifty-kilogram iron sphere’s gravitational force could almost be considered negligible, yet Lynn had used a long pendulum arm to magnify this minor effect, and then magnified it a second time through the reflection of light, presenting this subtle and usually imperceptible space distortion so vividly before them!

Harrov couldn’t help but express a sentiment similar to Rafael’s, wondering just how Lynn’s mind worked to come up with such a brilliant method.
