Since the truth is simple, we need to change our way of thinking to understand it.

Relativity and quantum mechanics are actually a deep understanding of the world. If it were easy to understand, Newton and Lagrange would have solved it.

Many (or even all) "axioms" in physics are generated when encountering experimental results that cannot be explained by existing theories.

To understand the constancy of the speed of light, you must first know at least the Michelson-Morley experiment. To understand the Michelson-Morley experiment, you must first understand how the Michelson interferometer works. To understand how the Michelson interferometer works, you must first understand the "interference" of waves. This goes all the way back to Fresnel, Fraunhofer, Thomas Young... and even Newton and Huygens.

Thank you very much. I know all this, but I still can't intuitively understand the constancy of the speed of light. Can you explain the constancy of the speed of light from an intuitive perspective?

"But I still can't intuitively understand the constancy of the speed of light. Can you explain the constancy of the speed of light from an intuitive perspective?"

cannot.

Not to mention you and me, most physicists around the world did not understand it at that time, so much so that when the Nobel Prize Committee awarded Einstein the 1921 Physics Prize, it was not because of Einstein's theory of relativity, but because of Einstein's work on the photoelectric effect.

Since most physicists in the world do not understand it, including the members of the Royal Swedish Academy of Sciences, and even the "pioneer of relativity" such as Poincare, who first proposed the principle of relativity and gave the mathematical form of Lorentz transformation, does not accept Einstein's theory of relativity, I am afraid that it is difficult for anyone in the world to "explain the constancy of the speed of light from an intuitive perspective." Originally, the "constancy of the speed of light" is very contrary to people's common sense.

I remember that some time ago you had to explain something "from the perspective of quantum mechanics."

Quantum mechanics, which is just basic knowledge, is a course that undergraduate physics students have to spend 90 to 110 hours on and half of the students fail.

If you are really interested in this and are willing to spend some time to understand this issue, you can take a look at the following books.

The first one is a short booklet written by Einstein himself.

The second is a general physics textbook written by Zhao Kaihua and Luo Weiyin for the Department of Physics, in which the theory of relativity is introduced in Chapter 8. But I strongly recommend that you start reading from Chapter 1, and then read Chapter 8 after you have almost understood the first seven chapters.

I don't know what happened, but Einstein's "An Introduction to the Special and General Theory of Relativity" could not be uploaded.

Try sending it again.

If you really want to understand this problem, you should first make up for the basics, which will probably take several years of hard work and require you to have a high enough talent. If you don't have enough understanding and a weak foundation, it is normal that you won't even be able to find the door even if you spend your whole life.

The first article you posted said: "The zero result of the Michelson-Morley interference experiment can be well explained by the view that the speed of light relative to the light source is constant." The book I posted on the 10th floor, pages 365 to 366, has used astronomical observations to prove that the view that "the speed of light relative to the light source is constant" is wrong.

Thank you very much. I don't agree with your statement of spending a lifetime. Schrdinger himself could not understand the Schrdinger equation at all.

If it takes a lifetime to understand the theory of relativity as you said, wouldn't it become metaphysics? The emperor's new clothes, don't be blinded by authority.

There are many people who cannot understand quantum mechanics even in their entire lives. Ordinary people just cannot see or ignore these people who cannot understand quantum mechanics even in their entire lives.

I myself am one of those people who has not been able to understand quantum mechanics in my entire life, or at least not fully understand it, and only knows the basics.

Poincare, mentioned on the 7th floor, was the world's top mathematician, physicist, and astronomer at the time. Poincare never understood the theory of relativity in his life. This is what Einstein himself said.

Einstein opposed the Copenhagen interpretation of quantum mechanics throughout his life and had many debates with Bohr, but Einstein was ultimately defeated by Bohr. Although Einstein can be said to be one of the founders of quantum mechanics and won the 1921 Nobel Prize in Physics for his research on the photoelectric effect (it was the research on the photoelectric effect that made the concept of quantum accepted by most physicists),

"The Emperor's New Clothes: Don't be blinded by authority"

Isn't Einstein authoritative enough? Bohr was not "blinded" by Einstein, that is, he did not believe in Einstein's "things". However, you and I (and Chunyang) probably do not belong to the category of "not being blinded by authority".

Unfortunately, what you said only shows that you have not understood the meaning of my post on the 12th floor at all.

Everything changes with time. To say that it remains unchanged is limiting.
