What is the reason for whether the ether exists or not, and whether the ether exists or not?

Ether is a historical term, and its meaning has evolved with history.

In ancient Greece, ether referred to the blue sky or upper atmosphere. In cosmology, ether is sometimes used to denote the matter that occupies the space of celestial bodies. In the 17th century, Descartes was a philosopher who had a major influence on the development of scientific thought, and he was the first to introduce the ether into science and give it a certain mechanical property.

In Descartes' view, all forces between objects must be transmitted through some intermediate medium, without any over-distance action. Therefore, space cannot be empty, it is filled with the medium matter of the ether. Although the ether cannot be felt by the human senses, it can transmit the effects of forces, such as magnetism and the force of the moon on the tides.

Later, the ether was largely associated with the wave theory of light as a carrier of light waves. The theory of the wave of light was first proposed by Hooke and further developed by Huygens. For quite a long time (until the beginning of the 20th century), the understanding of waves was limited to the mechanical vibrations of a certain medium.

This medium material is called the wave load, such as air is the load of sound waves.

Since light can propagate in a vacuum, Huygens proposed that the medium material (ether) that carries the light wave should fill the entire space, including the vacuum, and be able to penetrate the usual matter. In addition to being a load for light waves, Huygens also used ether to illustrate the phenomenon of gravity.

According to current scientific research, the fact that ether does not exist.

Albert Einstein denied the existence of the ether early on.

However, certain hypotheses about the ether are still the starting point for the study of the nature of the vacuum.

does not exist. What it says in high school physics textbooks.

Book III The Last Chapter.

You type the ether into the encyclopedia, and then you go to the entry, which may have something you want to know.

It does not exist, it is described in detail in A Brief History of Time.

Built on the foundations of classical physics. Because in Newtonian mechanics, velocity is relative. When people calculate the speed of light, are they thinking about how light moves relative to light?

In line with Newton's theory, the theory of the ether was proposed. Suppose the light moves relative to the ether. Later, high-precision experiments conducted by many scientists proved that the ether did not exist.

I think the aether exists because a lot of scientists believe in the existence of the aether.

Aether is a substance conceived by the ancient Greek philosopher Aristotle. It is an imaginary concept of matter in the history of physics, and its connotation has evolved with the development of physics. The word "ether" is a transliteration of the English ether or aether.

The ancient Greeks used it to refer to the blue sky or upper atmosphere.

It doesn't exist, that's what the scientists of ancient Greece conjectured.
