I Made Scientific Magic

Under Lynn's explanation, all the great wizards present continued to discuss.

According to this statement, the theory of constant speed of light does have some truth.

"Wait!" Dennis suddenly noticed a loophole, and asked in confusion. "Speaker Lynn, if you say it this way, then the principle of the constant speed of light should have a premise. The speed of light must be detected under the inertial reference system to be a fixed value!"

If it is in a non-inertial reference frame in motion, the situation will be different!

Probably because he felt that such words and expressions were not appropriate enough, Dennis beckoned and used the [Mage's Hand] to capture a large experimental vessel, filled it with water, and then threw a float on the water surface and tapped it.

Under the gaze of everyone, waves of water swayed on the calm water.

Water waves and sound waves are both mechanical waves, and their propagation principles are naturally the same. Dennis is going to use water waves as an example to point out the loophole of the constant speed of light.

"Now let's assume that this finger is a person who is swimming!" Dennis put an index finger into the water again, and then faced the direction of the water waves, and gradually approached the position of the float. If he is used as a reference at this moment, then Doesn't the speed of the water wave become faster? "

Naturally, a person moving in water cannot be used as an inertial frame of reference, but Lynn does not have this premise in the theory of relativity, saying that the speed of light is eternal in any frame of reference, which is obviously illogical!

"If light is just a mechanical wave, then it is true, but it is a pity that its special properties determine that light is different from other waves." Lynn looked at the confused people and explained. "Don't forget that the transmission of light does not require a specific medium, it can even travel in a vacuum!"

Dennis and the others frowned, this is indeed the biggest difference between light and other waves.

"Is it possible that it's just a medium that we haven't detected light yet?" Steger couldn't help but interrupted.

"About this, I have tried it experimentally. Unfortunately, this so-called medium does not exist!" Lynn shook his head, and then showed everyone the beam offset measurement cantilever he made.

This is actually a modified version of the Michelson-Morley experiment. He put a beam emitter at one end of the cantilever. When the switch is turned on, a beam of light will fly out, and then it will be divided into two beams by the beam splitter in the middle of the cantilever. In two different directions, it is finally reflected to the detection instrument by the reflector at the end of the cantilever.

You must know that the planet under their feet is revolving around the sun at a super high speed of 30 kilometers per second.

Assuming that the medium of light really exists in the universe, no matter whether it is stationary or moving at a constant speed, it is impossible to keep pace with the eternal star revolving around the sun.

It's like the float that caused the water wave to move. At this time, if you test again, you will find that the distance between the float and the water wave in front is shortened, and the distance between the float and the water wave in the back becomes farther.

Although the speed of light is extremely fast, the orbiting speed of the Eternal Star can only reach one ten-thousandth of the speed of light, and the deviation caused is very small, but for wizards with atomic-level sensing precision, it is enough to detect these slight changes !

"Unfortunately, I have done many inspections. No matter which direction the beam returns from, the position of the stripes on the inspection instrument will not change a little bit! This is enough to show that the medium of light does not exist, which means There is no fixed medium as a reference..." Lynn shook his head and said.

"If there is no medium for light, why does its speed have a definite value?" Steger said in great confusion.

Dennis and others are also very surprised at this point. The reason why the propagation speed of sound waves and water waves is determined is because they are transmitted in the medium.

To use an inappropriate analogy, it is like 10,000 people standing in a row, the first person slaps the second person, the second person slaps the third person, and this is passed on, so the force is transmitted speeds are equal.

If there is no medium, then the speed of light should be fast or slow.

Just as Lynn was about to answer, a voice rang out first.

"That's because light is an electromagnetic wave, and the propagation speed of electromagnetic waves in a vacuum is only related to the vacuum permittivity and vacuum magnetic permeability!"

At the same time as the voice sounded, the four speakers, Anthony, Harov, Aurora, and Vittorio, walked in from the door.

And the person who responded just now was Anthony!

Sturger and the other big wizards turned their heads and looked at the past. While greeting, they all looked at Anthony with envy and jealousy. A few months ago, the other party was just a big wizard like them. A wizard, but now he has become a legendary wizard aloft, the speaker of the wizard council.

Only Jeffrey's eyes showed no jealousy, but rather admiration. He was able to successfully complete the legendary promotion ceremony while understanding all kinds of weird phenomena of microscopic particles, which made him feel ashamed.

Anthony ignored these gazes, looked at Lynn and continued to speak. "The reason why I was able to discover that light is a type of electromagnetic wave was based on the derivation of Speaker Lynn's electromagnetic equations!"

However, in Lynn's equation describing electromagnetic waves, the oscillating electric field and magnetic field, the speed of which is only related to the two directionless scalar quantities of vacuum permittivity and vacuum permeability.

At the beginning, he even doubted whether this was an omission of Lynn. After all, any speed must have a reference object, just like the example Lynn gave at the beginning. The silver coin he fired could be It can be said to be fifty meters per second, or it can be said to be thirty kilometers per second, but the reference objects are different.

Unless it is the same as in the theory of relativity, the speed of light is the same for any reference object!

"Good!" Lynn nodded. "You can understand the permittivity and permeability as the 'resistance' of space to electromagnetic fields!"

"Space resistance?" Steger and the others thought about this concept.

"The three-dimensional space we live in can be regarded as a layer of membrane. The heavier the object, the deeper the depression will be formed in the space, which is the distortion of time and space. The faster the object will be the same..." Lynn tried his best It may be explained in the most convenient way to understand.

For example, if the same thrust is applied to a one-ton object, it can only be pushed by one centimeter, but if it is applied to a ten-kilogram object, it will fly out at an extremely fast speed.

So speed and mass must be related to some extent, so the relative mass formula is derived.

"As for why the speed of light remains constant in any reference object, I guess there must be an upper line of speed in the universe, and this speed is the speed of light!"

"Because light always moves forward at the maximum speed that space can tolerate, and cannot be surpassed, so even if you move away from light at a very fast speed, the measured speed of light will not change. After all, its speed has reached the upper limit of space , naturally cannot be improved in any form!"

Lynn once again threw out an extremely amazing point of view, using the insurmountable speed of light to explain why it is constant.

"Using a guess that obviously violates common sense to demonstrate another phenomenon that is even more contrary to common sense is simply ridiculous!!" A great wizard couldn't help but interrupted.

Sterger and Jeffrey were hesitant to speak, and they did not agree with Lynn's conjecture that the speed of light could not be surpassed.

Even the speakers like Anthony and Harov frowned.

"I don't think it's a problem to make bold assumptions about an unknown phenomenon and then carefully demonstrate it." Lynn shrugged and explained.

This is no longer a bold assumption, it can only be described in nonsense... Steger rolled his eyes, if it weren't for the fact that the person who proposed such an outrageous theory was Lynn, the star of magic, he might have already been mobilized to attack It's over.

Lynn naturally saw the confusion and doubts in everyone's eyes,

It is indeed very strange that there is a speed limit in space and the principle of the constant speed of light. Anyone who hears this conclusion for the first time can't help but refute it.

However, it is a fact, and it is an intrinsic property of space like Planck’s constant, gravitational constant, and strong coupling constant, and it is one of the basic constants of the universe.

Thinking of this, Lynn shook his head again and said. "I should have said before that all magic theories are a summary of the laws of things. It doesn't need to conform to our common sense, but our common sense needs to conform to the laws!"

"My light speed deflection experiment proves that light does not rely on a fixed medium for propagation. No matter where it is, the measured light speed will not change at all, which fully shows that the constant light speed is reasonable."

Lynn's answer is undoubtedly very concise, but fruitful, just like his argument of wave-particle duality, he deduces the argument based on the phenomenon.

Because the facts are there, they can only use such a theory as an explanation!

"Even so, I still can't agree with this conjecture. A light speed deflection experiment can't fully confirm the theory of constant light speed. Maybe there are other factors that affect the results of the experiment!" Steger questioned.

After all, there are loopholes in the theory of the constant speed of light and the inability of the speed of light to surpass these two concepts!

Dennis on the side also spoke. "According to the principle of relativity of speed given by you, Speaker Lynn, as long as I run after the light, then for me, the speed away from the light must be less than the speed of light. Conversely, as long as I run in the opposite direction of the light, then The distance between us per second naturally exceeds the speed of light!"

The rest of the great wizards also nodded, and they could think of countless similar methods. The so-called constant speed of light and insurmountable theory are like thin paper, which can be broken with one poke!

(PS: I have a headache from reading the theory of relativity recently. I will finish the next chapter as soon as possible after reading the theory of relativity. The cosmological constant in the setting that is not affected by the observer is one of the important forces of high-dimensional existence, so I have to write about it... )
