Does the aether exist in classical physics?

There are two dark clouds floating over the edifice of classical physics, the first is that the existence of the aether has not been proven, and the second is the mismatch between the theory and practice of black-body radiation. One of these two clouds developed the theory of relativity, and the other developed quantum mechanics. If the existence of the ether had been proved after the initial experiment, then Einstein's theory of relativity would not have appeared.

Newton's absolute view of time and space believes that there is an invisible and intangible substance in the universe, and all the speed of the sun, moon and stars is relative to this substance, which is called the ether, of course, the ether theory appeared very early and was not invented by Newton, but Newton is the main supporter of the ether theory. At the end of the 19th century, classical physics had reached its peak, and the classical physics edifice was about to be completed.

Therefore, scientists began to prove the existence of the aether, and the earth's orbital linear speed is about 30 kilometers per second, so the difference in the speed of light between the earth moving in the ether and the "downwind" and "upwind" will be 30 kilometers per second. Michelson and Morey, two experimental physicists, set up a test bench, two perpendicular light interferometers, which, if the aether were present, would skew the speed of light, which would cause the fringes on the interferometer to move. But the result was not as expected, and the interference stripes did not move at all.

This means that the Michelson-Morey experiment failed, they did not prove the existence of the ether, on the contrary, they proved that the ether did not exist (Einstein was only 8 years old at this time), such a result made physicists very puzzled and difficult to accept, and proposed various possibilities, such as instrument errors, errors in experimental principles, and so on. More than a decade passed in this way, and in the twentieth century, the little boy had grown up, and he thought that the aether did not exist. The principle of relativity, the principle of invariance of the speed of light, the Lorentz transform, etc., were put forward one after another, and finally these main points were unified and published in 1905, which is what we call the special theory of relativity today.

Therefore, Einstein proposed the theory of relativity on the premise that the ether does not exist, and the theory of relativity has been tested by experiments and phenomena, and some predictions have been confirmed. If the theory of relativity is not wrong, then the ether cannot exist.

The black hole of literature and science, the **** network invasion and deletion.

The aether does not exist because scientists have found in experiments that there is no deviation or movement. So for such a phenomenon, Einstein also gave the theory of relativity, so these can show that the ether does not exist.

Einstein's special theory of relativity proved that the ether does not exist and is the result of the mature development of the human mind. Asking questions and proving problems is a law in physics.

A: Aether does not exist in classical physics. Einstein's theory of relativity, which has given the results of scientific experiments, proves that the ether does not exist.

Aether does not exist, and the conclusion that aether has been overturned. The new experimental results proved that it was a mistake, and scientists have also come up with new conclusions and are correcting this error.

Of course, the demeanor in classical physics exists, and it is a result of the theory of black-body radiation, which gives us a perfect explanation for quantum science, so it is said that it exists.

The ancient Greek philosopher Aristotle first conceived a medium. ether, aether, akashic. Specifically refers to:

The stream of consciousness that makes up space, the first and most basic element created by the spirit world when it creates the material phenomenal world. All things in the realm of material phenomena live within it. It is the first of the five basic elements (earth.

Water. Fire. Wind. emptiness) in the void, the main voice. It is also the creator of the four essential elements.

It is also often used as a synonym for "space". Between the stars, the spiritual eye can observe that the space is composed of a dark red fluid-like stream of consciousness, forming a more stable shape of the space fluid, which is the ether. After the seventeenth century, physicists reproposed it to explain the propagation of light and the interaction between electromagnetism and gravity.

At that time, it was thought that light was a mechanical elastic wave, but since it could propagate through a vacuum, it was necessary to assume that there was an ether that had not yet been discovered experimentally as a medium for propagating light. This medium is omnipresent, massless, and "absolutely stationary," and the electromagnetic and gravitational forces are its special mechanical effects. The concept of ether was widely accepted by the 19th century, but scientists have never been able to prove its existence through experiments.

At the beginning of the twentieth century, with the establishment of the theory of relativity and further study of fields, it was determined that the propagation of light and the transmission of all interactions through various fields, rather than through mechanical media, aether was abandoned as an obsolete concept. Reference.

Galaxies are spinning much faster than we expected, which limits the amount of matter we can observe. One possibility that has long been suggested is that there is some unexplained matter between galaxies that has additional gravitational effects. But there is also the possibility that the visible matter we observe produces more gravitational pull than we previously thought.

That's where 'ether' comes in. The term "ether" was first coined by Aristotle, who believed that celestial bodies (the sun, moon, planets, stars) are made up of a fifth element, ether (the other four elements, earth, air, fire, and water), which, unlike earthly matter, is eternally unchanging and perfect. So the things that change in the sky, like meteors, comets, novas, are under the sky, in the air of the Earth's atmosphere, not in the stars and planets.

The natural motion of the ether is not a straight line towards the earth but an isokinetic circular motion around the earth, and the natural shape is also smooth and spherical because the ball or circle is the most perfect shape. The concept of "ether" explained by scientists is a background medium throughout the universe, and this concept has been circulating for hundreds of years.

Scientists have previously believed that it is the aether that allows light to travel in space, just as sound needs air or water as a medium to propagate and diffuse.

Some physicists believe that the Earth's movement in the aether creates an "aether current" that bends light waves, as if sound waves were deflected in the atmosphere. But the theory of ether was largely put aside in 1887 after the failure of experiments by Albert Michelson (winner of the 1907 Nobel Prize in Physics for his contributions to the study of optical precision instruments and their use in spectroscopy and metrology, known for his precise measurement of the speed of light and experiments on aether drift with unprecedented precision) and Edward Mooreley (an American astronomer who experimentally measured the change in the speed of light).

Michelson-Mooreley's experiment was based on the assumption that the entire space was filled with the light aether, which was thought to be immovable, and that the earth was moving through the aether. Therefore, light emitted in the direction of the Earth's motion should (or seems to be) travel faster than light emitted at right angles to the direction of the Earth's motion. The two beams of light are out of phase and have interference fringes.

Measuring the width of the fringes makes it possible to find the exact velocity of the Earth with respect to the ether. In this way, the "absolute motion" of the earth can be determined, and the absolute motion of all objects in the universe can be known from the motion of the earth relative to it. However, the end result of the experiment was that there were no distinctly wide fringes, so there was no difference in the speed of light in any direction in any environment.

Thus also overturning all doctrines about the ether. This means that the "etheric airflow" may not exist. Later, on the basis of his special theory of relativity, Einstein showed that light could propagate in a vacuum "without ether".

Classical physics is still true in some respects, but it's just not comprehensive. We all know that the greatest discovery in the course of human civilization is "modern science". Before science was born, human beings were ignorant, and many natural phenomena could not be explained;

Since the advent of modern science, we have not only recognized the real world, but can even use technology to "transform the world", so that human beings have changed dramatically over the centuries. What really opened the door of the temple of science was Newton's classical physics.

Therefore, Newton can be described as a "groundbreaking" figure in the field of physics, and in 2015, the British BBC radio station gave Newton the first place in the global historical figure influence ranking, so he is called "the incarnation of God on earth". However, after a lapse of hundreds of years, various innovations and breakthroughs in the field of physics have emerged one after another;

Classical physics is no longer the mainstream of our research. Once upon a time, Newton and others used "ether" to explain the universe and various changes in nature, believing that the ether is formless and phaseless, which is not only the source of light, but also the substance that causes gravitational fluctuations;

However, in the 19th century, the thunder and lightning bred by the "two dark clouds" over the physics world fell, and the "ether" disappeared. Maxwell and Einstein both proved that the ether does not exist, and the "theory of relativity" has replaced classical physics as the most mainstream and authoritative theory.

Even, to this day, we are still digesting many of the principles and ** of general relativity. So, is it possible for humans to claim that "classical physics" is wrong? I think the same can't.

Classical physics is imperfect, it can explain all the changes on the earth, but it cannot explain the various laws and phenomena in the universe, which is its flaw; However, we cannot say that a scientific theory is completely "wrong".

Maybe one day physics will change again, and someone will discover the "ether"?

That's right. Because classical physics is very mature and has no direct relationship with the ether, classical physics is correct.

Correct within a certain range. There is no absolute right in the scientific community, only correct under certain conditions, and the non-existence of the ether can only show that classical physics has certain limitations, but it cannot be completely denied.

The aether is a stream of consciousness made up of space, just like the water in the ocean, water can be formed regardless of gravity.

The concept of space is the same, you can control all the deformations of space, such as making the space of a bus the same as an airplane, it's just simple.

If there is a stream of consciousness, you can change objects at will when you reach the atomic level, and it is not a problem to turn stones into gold, which is only intermediate.

According to Einstein's theory of relativity, time and space coexist, and if you can change space, you may be able to change the timeline, so this ether can either not exist, and if it exists, it also plays the role of God.

Because with the development of science and technology, many physical phenomena have also broken through the original barriers, and the ether is just standing still, not keeping up with the development of the free ride.

Because it has been replaced by something new, it has become a thing of the past, and there is no value to be used.

Maxwell's electromagnetic equations were able to derive the propagation speed of electromagnetic waves without the help of any reference frame, and people at the time thought that it was meaningless to talk about velocity without a fixed reference frame, so they speculated that there is an absolutely constant reference frame and ether in the universe, and the velocity deduced from Maxwell's equation is based on the ether as a reference frame. This is where the aether theory comes from, but now it seems that this theory is so ridiculous that it does not need to be used to explain any ......
