Act 447. Speed ​​of Light

“First of all, the speed of light is not composed of the speed of light in vacuum and the speed of the selected reference frame. What demonstrates this is the latest interpretation process of the Newington-Holland equations.

"Secondly, the speed of light is not composed of the speed of light in a vacuum and the speed of the light source. The one that demonstrates this is the Armand flowing water experiment. It is formed by the light obtained by the same light source passing through two water flows in opposite directions. Interference fringe evidence.

"Thirdly, the speed of light is not composed of the speed of light in vacuum and the speed obtained by the surrounding objects dragging the ether. This can be proved from the light aberration caused by the Armand flow experiment and the observations of distant galaxies by astrology mages. .

"Finally, the propagation speed of light in a medium is not composed of the propagation speed of light when the medium is stationary and the speed of the moving medium. This is also proved by Armand's flowing water experiment."

Reiner wrote on the paper and turned his eyes to the other side of the table. It was the record of an experiment.

This is exactly the Armand running water experiment he mentioned many times.

This experiment is not a recent experiment, but an experiment designed by an intermediate mage named Armand Saul seventy years ago.

The process of the experiment is very simple. A light source array is used to emit a beam of light, which is divided into two beams with a spectroscope. The light is emitted from the same direction into two water tanks at the same time, and there are water flows in opposite directions in the water tanks. The light passes through the two water tanks and then converges, eventually forming an interference phenomenon. By studying the interference fringes, the speed change of the light can be known.

This experiment was designed to explain the ether drag effect in the past, but now it has become the cornerstone of Reiner's demonstration of his hypothesis.

From these points of view, light will not change its speed due to changes in the outside world and the medium. This is inconsistent with the principle of relativity of laws adhered to by mages in the past. How to resolve this disagreement is Reiner's starting point.

It was already the middle of the Moon of Flowing Fire, and the atmosphere of summer was getting stronger. Some open-minded girls had even changed into summer uniforms with cool short skirts.

The first mock exam of the magic test has ended. Graduation-year students are in the midst of intense final review, while students in other grades are also busy with the final exams that are gradually starting in various subjects. During the day, the campus seems quiet and tense. , only during dinner time in the evening, you can see students gesticulating with magic tablets.

Reiner put down his pen and stood up. Although he had a certain direction, he had to be cautious because he knew that the conclusion brewing in his mind might not be so easy to accept.

The light surrounded and intertwined around him, forming one formula after another. Reiner had briefly proved two of the relatively important ones, and the most important one was still in the hypothesis stage.

He decided to go for a walk.

Reiner, who was wearing a shirt, passed by the corridor. He could see the students carefully reading and reviewing in the classroom. He was quite relieved. He came to the Crescent Square and walked to the path shaded by trees.

At this time, the bell announcing the end of the morning class rang. Reiner looked in the direction of the teaching building. Students came out of the classroom one after another. He picked up his magic tablet and looked at the time.

It was exactly twelve o'clock noon.

In Reiner's mind, he and the big clock on the distant clock tower are like two different observers, each having their own time.

In the eyes of past mages, no matter how far apart they were or what state they were moving in, they all had the same time.

But Reiner didn't think so.

He raised his head slightly and looked at the sunlight scattered among the treetops. This light gave birth to life, but it was also a problem that had troubled mages for many years. It could be seen everywhere, but it was mysterious and unpredictable.

Reiner's thoughts flew to the sky.

He himself seemed to be a ray of light, traveling in the sky.

His speed is getting faster and faster, surpassing the speed of sound, constantly improving, approaching the true light.

At this moment, Reiner looked around and saw an astonishing scene.

The originally tall towers were getting shorter and shorter, the towering trees in the forest turned into low bushes, and the world seemed to shrink.

Reiner continued to accelerate. He felt an unprecedented resistance. Even if he exhausted all his strength, it would be difficult to continue accelerating.

His hands and feet felt extremely heavy, as if they had become a thousand times heavier. The more he tried to speed up, the heavier the weight became.

At this moment, a leaf fell from Reiner's side.

The leaves were spinning, spinning, and falling slowly, several times slower than usual.

The high-speed Reiner is in sharp contrast to the slow-moving leaves.

At this moment, Reiner looked at the time.

Buzz——

In an instant, all the images shrank rapidly. Reiner no longer had the speed to approach the light, and his consciousness returned to his body.

A fallen leaf blown down by the wind happened to fall slowly and fell to the ground as Reiner watched. This was a green leaf that grew in spring and fell in summer.

Feeling something in his heart, Reiner quickly left the path and returned to his office.

Around him, light intertwined to form a complex cluster of magic circles. This was Reiner's calculation circle.

From the calculation array, more rays of light appeared, forming one formula after another and one picture after another.

According to the Newington-Holland equations and the conclusions obtained from various experiments, the speed of light does not change in various reference systems and media, which is contrary to various existing laws of motion.

Therefore, in order to solve this problem, Reiner proposed a hypothesis.

That means the speed of light remains constant.

The speed of light in a vacuum will never change due to external conditions. It is always a fixed value. It is like a constant and cannot be changed.

Starting from this assumption, all the kinematic formulas around Reiner suddenly shattered.

Then, Reiner waved his hand, and all the formulas were reorganized again.

Reorganize based on the constant speed of light!

It can be seen that if the speed of light does not change, then when the speed of an object approaches the speed of light, its time will slow down. The timeline defined by mages in the past has expanded at this moment.

Then, continue to deduce from this that when the speed of an object becomes faster, the length measured along the direction of movement of the object will also become shorter.

Two formulas appeared around Reiner, and according to these two formulas, when an object reaches the speed of light, its length will shorten to zero, and its time will completely stop!

Buzz——

Reiner felt something in his heart. He closed his eyes. When he opened them again, the scene around Reiner had changed color.

The students walking outside the window, the wind blowing the leaves, and the birds flying high are all as still as frozen film.

Reiner saw the world.
