Aether theories - Wikipedia
In the history of physics, aether theories (or ether theories) proposed the existence of a medium, a space-filling substance or field as a transmission medium for the propagation of electromagnetic or gravitational forces.
A theory that supports the existence of a preferred aether frame and the anisotropy of the speed of light in the Earth frame. It explains the experimental results and the relativity principle based on measurement distortions and the compatibility with mass-energy conservation.
Ether | Substance, Aether, Wave Theory | Britannica
ether, in physics, a theoretical universal substance believed during the 19th century to act as the medium for transmission of electromagnetic waves (e.g., light and X-rays), much as sound waves are transmitted by elastic media such as air.
Demystifying the Aether: From Early Light Wave Theories to …
Nov 17, 2023 · The luminiferous aether has an intriguing history in the evolution of physics. This hypothetical medium was once thought to permeate all space and enable light propagation. But what exactly was the aether? Why did physicists posit its existence? And how did experiments and Einstein‘s relativity ultimately dismiss it?
Einstein-aether theory - Wikipedia
In physics the Einstein-aether theory, also called aetheory, is the name coined in 2004 for a modification of general relativity that has a preferred reference frame and hence violates Lorentz invariance.
Aether (classical element) - Wikipedia
Aether was the fifth element in ancient and medieval science, filling the region of the universe beyond the terrestrial sphere. It was also known as quintessence, the pure essence of the celestial bodies, and was used in alchemy and physics theories.

May 4, 2024 · The provided research paper explores the Aether Physics Model (APM), a novel theoretical framework that aims to unify and expand upon the Standard Model of particle physics.
How Luminiferous Aether Led to Relativity - PBS
May 11, 2020 · Paul Dirac suggested that a “particulate aether” could explain the near vacuum state of spacetime in which quantum physicists believe particle pairs are quickly born and destroyed.
Einstein killed the aether. Now the idea is back to save relativity
Oct 30, 2019 · The luminiferous aether, once rejected by Einstein's theory of relativity, is now being revived to explain dark matter and dark energy, and potentially unify physics. Learn how the aether could...
aether. A difficulty then began to appear, which grew in importance until it finally killed the aether. If the aether is assumed to exist as a real thing, it should have a velocity. The physicist should be able to determine this velocity or, stated more ac-curately, the velocity of the aether relative to the earth or of the earth relative to ...
