Физики не любят это признавать: квантовое поле и есть ЭФИР?

What is ether? Did it really exist? Does this idea have a place in modern physics? In this video, we explore in detail one of the most enigmatic concepts in the history of science: the luminiferous ether. The ether was once considered an invisible medium filling the entire universe and serving as the basis for the propagation of light, electromagnetic waves, and even matter itself. Later, Albert Einstein's theory of relativity supplanted the classical concept of ether. However, many of the ideas underlying this concept unexpectedly resonate with modern quantum field theory, vacuum fluctuations, dark energy, and much more. And the most interesting thing is that if you answer something like "there is no ether," you'll be wrong. The same would be true, however, if you say that ether exists. This is an interesting question, and there is no direct answer. In this video, you'll learn what ether is in simple terms, why the idea of ​​ether has existed in different cultures and eras, what functions ether has served, how scientists tried to detect it, what the famous Michelson-Morley experiment revealed, and how Einstein changed our understanding of space and time. We'll explore more modern concepts and recall how mass, fields, and vacuum are related, what a quantum vacuum is and why it resembles ether, how the Casimir effect and the Lamb shift show why a vacuum isn't truly empty, and why dark energy resembles the modern equivalent of ether. What "two clouds" in physics led to the revolutions of the 20th century. This video will be of interest to anyone who wants to understand whether ether exists today and why there's so much debate about it.
