I Pioneered Scientific Magic chapter-325-light-needs-only-a-second-to-circumnavigate-the-continent-seven-and-a-half-times

Under Lynn's guidance, the wizards present finally grasped the situation, gazing at the gears spinning ceaselessly before them, their faces a mix of astonishment.

This gear mechanism had managed to block all attempts of light particles from passing through its teeth, without exception!

"This isn't magic!" Yassos exclaimed in disbelief.

This eerie occurrence directly disproved the notion of limitless light speed! Otherwise, every beam passing through the gaps would instantly return, with no possibility of being obstructed...

"It's feasible, this method is truly feasible!" murmured Glenn.

Just as Lynn had said, they had achieved half the success. All they needed now was to continue increasing the speed; those returning beams would gradually move backward, passing over the obstructive gears to reach the next gap!

"How fast is it spinning now?" Raphael urgently inquired.

"Twenty-five revolutions per second!" Lydia reported loudly.

"Increase it further, faster!" Raphael shouted.

Lydia glanced at Lynn and then, as instructed, increased the internal combustion engine's power once again. The gear's speed immediately surged several notches higher, described only as extravagant—a fierce noise reverberating around them.

So intense was it that even onlookers like Elok felt a tinge of concern, fearing the contraption might suddenly break apart.

Even though they accelerated to thirty-five revolutions per second, the light spot remained absent, but the gear's speed was approaching its limit!

Despite Lynn instructing them to reduce the gear spacing between 0.5 centimeters, the gear's circumference still reached a staggering seven meters. Under such high-speed conditions, it was on the verge of collapsing at any moment!

"Stand back, I'll handle this!" Harof stepped forward, interrupting the internal combustion engine's power supply, instantly using magic to accelerate the gear beyond forty revolutions!

To ensure precision, Harof didn’t increase the speed too rapidly, instead opting for a balanced pace...

When the disk's speed exceeded fifty-two revolutions per second, every wizard present could distinctly witness a prominent light spot reappearing on the lens!

This indicated that the light beam passing through the first gap had returned from the second!

As the crowd cheered jubilantly, the entire disk exploded, sharp fragments flying in all directions like the keenest of knives!

Screams erupted among the crowd, but thankfully, Harof prevented the experiment from causing further accidents. The flying disk fragments seemed to sink into a sludge, slowing down gradually due to the effect of a delayed barrier, eventually hovering in mid-air.

"What was the speed just now, Speaker?" Raphael asked excitedly.

"It was fifty-two revolutions per second!" Harof affirmed confidently.

This value was unquestionable!

Raphael immediately calculated in his mind.

Seven hundred and twenty teeth multiplied by eight kilometers multiplied by a speed of fifty-two revolutions... which means...

Twenty-nine thousand nine hundred and fifty-two kilometers per second!

As the wizards calculated this figure, incredulity painted their faces. It was unbelievably fast... No wonder they couldn’t track the trajectory of light, no matter how they measured it earlier.

"Does this mean light can circumnavigate the Eternal Star's entire circumference in just one second?" Witch Nancy suddenly realized.

The circumference of the continent beneath their feet was merely forty thousand kilometers.

"Isn’t this a bit exaggerated?" Sanchez furrowed his brow. Nearly three hundred thousand kilometers per second was nearly indistinguishable from instant arrival within their realm of understanding.

"Only at such a speed can it traverse the vastness of the universe..." Aurora reminded them.

For instance, from the sun to this Eternal Star, the nearest point is around 140 million kilometers, and even at the speed of light, it would take over eight minutes!

Yet, in the face of such distances and speeds, even legendary wizards like them seemed as tiny as dust...

"So what we see daily is the sun's state from several minutes ago!" Lydia counted on her fingers, abruptly reaching a startling conclusion.

Wizards like Yoland from the Prophecy Guild suddenly realized they might measure distances between planets and their relationships using light speed, a universal measuring tool that would easily allow them to calculate previously elusive data.

Of course, this premise required them to calculate the speed of light's propagation in the true vacuum of space...

While the wizards were astonished by the terrifying speed of light, Lynn was thinking about something else entirely.

The light speed in both worlds was astonishingly close...

Quietly contemplating in his mind, if the data in the genius brain was accurate, the light speed measured in his previous life was 299,792 kilometers per second. The minuscule difference might be due to measurement precision issues...

Could this prove that the two worlds existed within the same universe?

This wasn't an implausible notion. While the previous federation hadn’t discovered magic, humanity hadn’t even fully grasped the tiny solar system, akin to tribal people living in the desert, believing the sandy expanse to be the entire world.

However, the universe's vastness surpassed everyone's imagination. Perhaps in some distant star system, there existed a miraculous substance called magic, or maybe energy?

Nevertheless, the similarity between the two worlds was remarkably high; it could also be another Earth in a parallel universe...

But these speculations weren’t something they could verify now. Lynn didn’t invest too much effort in this, utilizing gears of varying teeth counts, prepared long ago, to reattempt several times, verifying the accuracy of this experiment.

The final data showed some fluctuation, approximately a difference of several hundred meters.

For the wizards present, this result was incredibly satisfying. Compared to the colossal volume of light speed, such a discrepancy was negligible.

Some even speculated if light, like the speed of sound, varied in different regions, hence the fluctuation in measurements.

Only Lynn himself was slightly dissatisfied. Of course, a more precise determination of light speed was better. But given the current rudimentary conditions, it was impossible to create a more accurate instrument in the short term. The only feasible methods were gears and octagonal mirror experiments, both convenient yet unavoidably prone to slight errors.
