"Ah, it's a really nice day, speaking of which, my lord, is it scientifically possible that we will never be able to run faster than light?"

On a rare good day, Jian Yi was lying on the roof of the house and soaking in the sun, when suddenly Emilia was lying next to him and asked. Pen, fun, pavilion www. biquge。 info

"Huh? Why did Emilia ask that? ”

Jian Yi suddenly didn't understand, you love Milia, as a demon, as far as you are concerned, it is already an unscientific thing, and from the mouth of an unscientific demon asking yourself such a scientific thing, Jian Yi suddenly felt curious.

"Well, I don't know the specifics, but it should be like this, it seems to say that the speed of light is an absolute speed in our universe."

Seriously, it's really not very clear about science or anything, but about the speed of light, there is a pseudo-scientific story in the gentleman's world Jian Yi but remembers it very clearly.

And this pseudo-scientific story seems to be still high-end, and it seems to be called "the race between Einstein and the light lady".

It is said to be a basic thought experiment of a special Moe Niang theory born from the combination of the special theory of relativity in modern physics and the two-dimensional Meng Niang theory.

Listen to this Haotou, it's high-end enough, right?

It is said that there was a little girl named Albert Einstein, and in her autobiography, Einstein recalled that she fantasized about herself racing against the light lady in a cosmic vacuum.

She reasoned that if she could move next to Ray Lady at the speed of light, then she should be able to see Ray Lady become "running but still and still".

"Huh? Husband-sama? What is that? Sounds amazing, doesn't that sound? Is Albert Einstein a girl? ”

Emilia asked with some confusion after listening to what Jian Yi just said about "Einstein and Light Niang racing".

"Well, don't worry about these details, how about it? Is Emilia interested in hearing this story? ”

Jian Yi, who was also basking in the sun anyway, felt a little bored, so he asked Emilia if she would be interested in listening to her story.

"Hi Hi! Husband-sama, please tell Emilia, it seems to be very interesting. ”

Emilia looked genuinely interested.

"Okay, I'm going to think about it......"

Jian Yi nodded, and then recalled the story in his mind.

Emilia should know that the running speed of the light lady in the vacuum is 299792458m/s, and the abbreviation is c. At first, it was said that the European pie would shake when the light lady was running, but because the light mother had a short wavelength, it was poor milk.

So we can't feel the existence of the light mother, and in its scientific language, the fluctuations can't be seen with the naked eye.

Little is known about the nature of the light girl.,People have used the concept of mechanical wave girls.,Imagine that there must be a kind of light wave that can spread the light wave is the so-called husband of the light girl.。

The husband of the light lady is an elastic substance, and its name is "ether". Many physicists believe in the existence of the "ether", and regard this ubiquitous "ether" as her husband's absolute inertial frame, and it has become the goal of many scientists to verify the existence of the "ether" with experiments.

But then another person who died proposed: If the speed of the light speed is c when I am stationary, then I am chasing the speed of light in a car with a speed of v, due to the interference of the ether, is the speed measured c-v? So if the speed of the car you drive is also c, do you see that the light lady is stationary?

This problem is actually true when it is set of mechanical wave girls, and since the birth of the painful Maxwell equation and Hertz's experiment, people have finally realized: the light lady is actually the sister of the electromagnetic wave girl, and the running speed of the electromagnetic lady is the same as the light girl, which is 299792458m/s, and the existence of the so-called husband of the light lady has become an urgent problem to be solved.

Later, someone did this experiment, in 1887 Michelson and Morey did in Germany, using a Michelson interferometer to measure the difference between the speed of light of two perpendicular lights, the speed of two light speeds when running at an intersection, and then subtracting to get the difference, to see if the difference changed. It turned out that no matter how you measured it, the difference between the speeds of the two light-speeders running at the intersection was zero. Now something has happened, and why it will be zero has become a headache for physicists.

After Lorenz proposed the Lorentz transformation that all physics college students had a headache for, Poincaré and Einstein decided: throw away the ether and admit that the light lady is single, but how to explain to the physics mother has become a top priority, so Einstein decided to let the physics mother be the referee, and he and the light mother run a lap, measure the speed, and see if he will see the light speed mother is running but is stationary.

As for the final result, of course Einstein didn't run the light girl. In other words, Guangguang Niang is single, and she has no husband. This is a boon to some gentlemen.

Of course, this has also become one of the two fundamental pillars of special relativity: the principle of the invariance of the speed of light has an ideal experimental basis. The relativistic equations that were later written on this basis revealed the fact that when the speed of a high-speed object approaches the speed of light, the mass approaches infinity.

"Well, Husband-sama, I don't understand what you're talking about......

Emilia said to Jian Yi with a halo in her eyes.

"Haha...... Is it? Well, I don't really know much about it myself, but I used to joke with my physics teacher when I was in a physics class at school. ”

"Huh? Husband, is there anything like that? ”

Emilia's eyes were full of incredulity.

In her mind, the students who dare to braided with the teacher in class are the legendary little yellow hair or something, but Jian Yi is not a little yellow hair.

"Well, I remember that I accidentally fell asleep in physics class, and then I was discovered by the physics teacher, and I happened to talk about the speed of light."

"So the physics teacher kicked me up while I was asleep, and asked me to answer that if my speed was v, then the speed of light I saw should be c-v."

"Although I was a little dazed at the time, I still knew that this statement was wrong, but probably because of the low blood pressure when I got up, I subconsciously answered ......"

Speaking of this, Jian Yi smiled a little at that time, feeling very stupid and naïve.

"Husband-sama? How do you answer your teacher? ”

Emilia continued.

"Well, I was quick to speak, and I said, "Huh? Isn't Lightspeed Niang single Wanglai? If there is a husband or not, how can you use the concept of husband and wife wave (mechanical wave)? ”

Jian Yi didn't hesitate to answer Emilia.

"What happened to you, Lady Nama? Didn't your teacher punish you? ”

Emilia couldn't imagine what it was like to joke with her teacher.

"Of course, there was a punishment, and the physics teacher yelled at me at that time: What's wrong with being single? Although the world is full of the sour smell of love, I still exude the fragrance of singleness! Look down on singles! You give me a penalty station in the corridor, and the toilet is for you this week! ”

Thinking of that time, Jian Yi himself felt a little funny.

"Isn't it? Husband-sama? You're kidding people! (To be continued.) )
