What is Aether: Definition and 54 Discussions

MOSART (Moderate Spectral Atmospheric Radiance and Transmittance) is an atmospheric radiative transfer algorithm developed by the US Department of Defense. Development has halted as funding for the project has ended. In order to continue development, Computational Physics, Inc. (CPI) has created AETHER (or Atmospheric Effects on Transfer of Heat and Environmental Radiation), built from MOSART.

    A Thought Experiment: Aether Medium

    I would like to conduct a thought experiment. If some form of medium exists, what would it be made of? What form would any constituent parts take? Would those parts exhibit any properties? How would they function as a medium? What relation would the medium have with atoms and other particle...

    B Does QM implicitly define an aether?

    I'm a newbie in all this, so I'm sure I'm wrong. :) There are several schools of thought about quantum mechanics: Copenhagen, many worlds, pilot wave,... etc.. They all have, as far as I know, in common the Schrodinger equation. And here I could be wrong in my assumption: It doesn't matter if...

    Need for Lorentz transformation in pre-relativity period

Why was it necessary for the velocity of light to be invariant between different inertial frames and hence what was the need for Lorentz transformation when it was believed that velocity of light was constant with respect to...

    How do we eliminate the existance of luminiferous aether?

    According to Maxwell's equation, the speed of light, ##C_0 = \frac{1}{\sqrt{\epsilon_0\mu_0}}##, is a constant regarding to some form of medium, called luminiferous aether. Shortly after the death of Maxwell, Michelson-Morley Experiment shows that the speed of light is constant regarding to the...

    Equations of Gyrostatic Aether: McCullach & Kelvin

    I would be interested in the equations of a gyrostatic ether as brought up by McCullach and Lord Kelvin, best in a modern notation.

    Is there an aether to determine if an object rotates?

    The Case Against The Word Aether

    The Case Against The Word "Aether" Many BSM theories involve a space-time that has properties rather than being "nothing" or omnipresent field or substance, but the word "aether" as a description for that "non-nothing" vacuum between Standard Model particles is long past its due date as a...

    19th-century constraints on properties of the aether

    Did physicists ever try to put empirical constraints on the properties of the aether? I recall reading a popularization by Isaac Asimov in which he remarked that the aether would have had to have a very low density, and then to explain the high speed of light it would have had to have a...

    Is Light's Medium the Luminiferous Aether or the Electromagnetic Field?

    Light as a wave: Interference and diffraction of light indicates light is a wave. Other waves like sound or water waves require a medium to propagate. The speed of the wave is defined relative to this medium. So what is the light’s medium? And can we measure our speed relative to the medium by...

    The Higgs field and the aether

    Why is the idea of Aether being attached to Earth questioned?
