What exactly is the aether that Lily keeps mentioning during the week?

Aether is an invisible and intangible substance.

It's like time, you can't see time, you can't touch time, you can feel the change of time.

Generally speaking, the ether is the food of everyone's spiritual world.

Please take a closer look at the following explanation:

Ether is a hypothetical medium for the propagation of electromagnetic waves, but it has since been proven to be non-existent.

In the 19th century, scientists gradually discovered that light is a kind of wave, and most of the waves in life need a propagation medium (for example, the transmission of sound waves needs to use air, and the propagation of water waves needs to use water, etc.). Influenced by traditional mechanical ideas, they hypothesized that there was a substance called aether everywhere in the universe, and that it was this substance that played a role as a medium in the propagation of light.

According to Maxwell's equations, the propagation of electromagnetic waves requires an "absolute" frame of reference, and only in this frame of reference does the speed of light have the value predicted by Maxwell's equations c= frac}. where varepsilon 0 is the vacuum permittivity and 0 is the vacuum permeability. This "absolute frame of reference" is the ether.

The measured speed of light in other frames of reference should be the vector sum of the speed of light in this "absolute" frame of reference and the velocity of this "absolute" frame of reference relative to the observer.

According to the conjecture at the time, the aether filled the entire universe, and electromagnetic waves could travel through it. The Earth revolves around the Sun and has a velocity v relative to the aether, so if the speed of light is measured on Earth, the values measured in different directions should be different, with a maximum of c+v and a minimum of c-v (there is an assumption that the aether is stationary relative to the solar reference frame). But even if the aether is not stationary relative to the solar frame of reference, the values measured in different directions should be different).

But in 1881-1884, Albert Michelson and Edward Morley conducted the famous Michelson-Morey experiment to measure the relative velocity of the Earth and the ether, measuring the speed of light in different directions. However, experimental results show that there is no such difference in speed. This actually proves the principle of invariance of the speed of light, i.e. the speed of light in a vacuum has the same value in any frame of reference, regardless of the relative velocity of the frame of reference, and the ether does not actually exist.

Later, many experiments supported the above conclusions.

The theory of ether has been ingrained in people's minds for a period of time, profoundly influencing the thinking of physicists. The famous physicist Lorentz deduced the Lorentz transform formula that satisfies the conditions of electromagnetism covariance, but he could not abandon the idea of ether. Albert Einstein boldly abandoned the aether theory, believing that the speed of light is the basic principle, and used this as one of the starting points to create the special theory of relativity.

Although it turned out that there was no ether, the ether hypothesis still left traces in our lives, such as Ethernet.

That is, ether can also be a faith. Although he doesn't really exist, he hypothetically exists for so long, and that's exactly what happened in the movie, just like Lily Chow, her ether, her faith, you believe in her, and you feel her ether, even though it's something that isn't there at all, she just sings.

That's it.

See for yourself ... A lot of people have passed ...

Ether. Originally a concept in the science of physics, it was fictionalized to explain some natural phenomena that could not be explained at the time.

Target. This imaginary substance is considered to be a more fundamental natural being, in which all matter exists, as a cosmic medium. The universe exists in it, just like Yusheng.

Exist in the same way as in water. It should be transparent, yet ubiquitous, filling the entire universe. Unfortunately, later developments in physics proved that this was a false concept of the fountain, and that the aether did not exist.

However, the concept of ether has not died out because of this, on the contrary, due to its legendary background, more and more modern people want to borrow the extended meaning of the word ether to express their unique ideas, such as the computer Ethernet network we see every day.

In the book [All About Lily Zhou], I think the author uses the extended meaning of the word ether to represent a state of life, an empty faith. Just like the original meaning of the word ether--- it represents: something that is everywhere and cannot be escaped (the original meaning of ether is something that fills the universe, it must be everywhere, and since we live in the universe, we are destined to be unable to escape it), something empty (anything can live through the ether and live in the universe, so the ether must be)."Hollow", which can be extended to life"Emptiness"The concept of a human belief (the aether was not discovered by physical experiments, but was created in human imagination, and scientists at that time were very willing to believe in its existence, so it can be called a belief.

Based on the above analysis, I believe that the word ether in this book represents a suffocating state of life, an abstract and empty faith.

In fact, the ether is an imaginary object that fills space, and Descartes believed that all forces between objects must be transmitted through some intermediate medium, matter, 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.

Even the medium of light is the ether.

Physically, Lily Zhou's so-called ether is the 'breath' in this world that humans can't explain, and for Lily Zhou fans, the ether is the prototype of the energy given by Lily Zhou, and Lily Zhou composes music with aether and transmits it to fans.

But Lily Zhou's ether world is undefinable.
