Talk:Aether theories

message: Where the existing aether page sets out a particular historical view of aether theory (with some parts that seem to be stirring up some heated disagreement and claims of subjectivity), I put up this page as a more basic, hopefully neutral listing and jumping-off page to different aether theories.
The list is rather short at the moment. I know that there were loads of these things being suggested and shot down over the centuries, so if you can think of any noteworthy theories not listed here, please add them as a one-or two line bulletted entry, if you need more than that to describe it, give it its own page and leave a bulletted link to that page here. I did think of also doing an "aether theories" category, but at the moment there don't seem to be enough relevant wiki pages to justify it.

message: Re-adding the "Further readings" section after an accidental delete, I've left out the "obsolete theories" category tag because of the recent interest given to a modified verson of an ether theory.  Namely, there is some talk that vacuum quantum flux has fluid-like properties, which may be simialr to those of a perfect fluid.  I know I should dig up the articles on arXiv.org before saying something like this, but for the moment I want to enter it into the discussion.  Shpoffo 06:31, 6 June 2007 (UTC)

message: I thought this was amazing. Apparently, the Aetherometry article (which currently links here) influenced these people to write a book on the ignorant fascism that is wikipedia. It seems they are constituents of the theory, and felt NPOV violated. These paranoids became so enfuriated by their inability to contaminate the encyclopedia, they actually wrote a book about that seems to present wikipedia as some sort of conspiracy. Regardless, it seems the article was portected over all, and you should all be proud. Shaggorama 10:54, 1 March 2006 (UTC)
thread_title:  Hating on wikipedia 

message: I removed the following text:
:In its original and fundamental form the aether is both the medium of space, and the fundamental building blocks of all material substances.  Its properties therefore include all that is observed.  In this context there exist no physical process or theory that would be considered as aether-free.  In more modern theories this stuff of space are designated as field theories. These dispense with the concept of a medium and assign or designate the properties of the medium as fields which are then considered fundamental.
I'm not sure this is entirely accurate.  It would be easier to untangle if references were made to particular versions of the theory.  For now, I've replaced it with something shorter that mainly lets the various individual sections speak for themselves.  Perhaps a better overview will re-grow from scratch, or someone will fix this one. -- Beland 19:40, 16 April 2006 (UTC)

thread_title:  typography 

message: The recent approach to Luminiferous Aether concept is based on idea of inertial environment composed of scale invariant particles (so called unparticles), which are of infinite high matter and energy density. Such idea comes from Oliver Lodge and his Electric Theory of Matter from 1904. The AWT is currently subject of private research.
The AWT concept is consistent with idea, the Universe is formed by interior of black hole and it's surprisingly effective in explanation of nature of strings, protosimplex and spin foam, considered by string, Heim's and LQG theories, which can be considered as a density fluctuations of Aether. The vacuum foam is considered as a scaled down version of dark matter structure. Because in such environment most of energy spreads in transversal waves, it's consistent with Lorentz invariance approach of relativity theory. Because the foam gets more dense under vibrations, the mass density of foam is proportional to energy density, from this the quantization of energy density follows.
By such way, the AWT appears to be conceptually capable to reconcile most existing physical theories together with unparticle, constructal and process physics.  —Preceding unsigned comment added by 194.213.42.170 (talk) 16:43, 4 March 2008 (UTC)

thread_title:  Cleanup 

message: "Aether and the theory of relativity" was a title used by Einstein in a lecture on general relativity and aether theory. Einstein said that general relativity's gravitational field parameters could be said to have all the usual properties of an aether except one: it was not composed of particulate bodies that could be tracked over time, and so it could not be said to have the property of motion.  The general attitude to this amongst physicists today seems to be that Einstein's comments don't count because they stretch the idea of aether theory too far: it is argued that a "non-particulate" aether theory is not really an aether theory, or at least, it doesn't correspond to the idea of "historical" aether theory that is currently taught.  
Such a view, however, contradicts the continuum concept of space-time and fields and Einstein's statements in "Aether and the Theory of Relativity", May 5th, 1920:]
"More careful reflection teaches us, however, that the special theory of relativity does not compel us to deny ether." and "To deny the ether is ultimately to assume that empty space has no physical qualities whatever".

thread_title:  Propose a merge 

message: There is something that a (now dead) self-style historian on the developement of Physics point out to me when I was a student is that conventional history has it that we abandoned the idea of the Aether to explain the propagation of light waves in favor of the vacuum defined according to relativity.  But did we really?  The vacuum isn't a "nothing".  E.g. just from a non-quantum mechanical perspective the impedance of free space is about 377 ohms. This value is not zero.  Also the Dirac sea which came later in quantum mechanics and becomes the ancestor of quantum field theory is filled with energy levels.  This historian contended that we really did not give up on the idea of the Aether after all but simply attributed different properties to it. (unsigned)

replies: text: The problem is that using a word that used to mean one thing to mean a multiplicity of new things is pointlessly confusing.

thread_title: Well done Tim

message: This relates also to "Did we really throw out the idea of the Aether after all?" above.
I added a quote from Robert B. Laughlin on the situation of ether in contemporary theoretical physics and why physicists don't call it 'ether'. I think it goes far in explaining why sources about post special relativity ether are so fuzzy about it.
I would also suggest removing the first sentence in the following section "Modern analogies", "In physics there is no concept considered exactly analogous to the aether." It is at least apparently contradictory to what I added and has no source or citation. It seems to me that what Laughlin says goes beyond mere analogy, in any case, rendering the sentence superfluous.

message: pseudoscience is a pejorative term and assumes the person declaring something pseudoscience has all knowledge and understanding.
This is certainly never true. In my life time I have see many bad and impossible theories proven. HHMI once fired a scientist for idiocy who later won a Nobel prize for his pseudoscience.  Who knows haw many dies without the benefit of the medical implications of that theory. When research is in an area we do not understand it is impossible to determine something is "pseudoscience" until we have valid science to explore it with. One day Quantum Theory May be Science, for now it is a very useful and poorly understood theory. All doctrines produced from it could be false but they are the best we have to work with now.

thread_title:  Lorentz ether theory 

message: Nikola Tesla advocated that all physics in the space is of EM origin. Including gravity, but the frequency could be very-low. (hours for one period). If we have aether as a medium and EM propagating through this "substance" then there must be more dense parts of space and less dense parts of space. Otherwise propagation of a "wave" is not possible. The space must have variable density. Where the speed of wave is high, the density is low and vice versa. And there seems to be nothing affecting this density as much as gravity, because its frequency (would be) is so very low.  It would also imply that speed of light is not absolute. It is 300.000 km/s only for the "normal density" of space. 
Another interesting idea is that, the aether must have a dampening factor affecting EM, which is very low for high frequency (light) and gets to be much more low frequency (gravity), because we know that force of gravity drops of quickly, but light appears to be traveling without obstruction. Even for low frequency audio you need very high energy and for high frequency (MHz) comparably much less energy is needed to travel the same distance.
If stars are very far, is there some expected reduction factor due to distance used to account for loss of energy due to distance of the star when looking at its light? 
This could actually be proven and measured, because the speed of light at reasonable distance from earth in space in area of lower gravity should be more than if measured close to some object like earth, where the gravity is more (and space is denser).

thread_title:  External links modified 

message: The section is largely false and unrelated to aether theories and should be removed entirely.
The section  Quantum vacuum is false, QFT doesn't describe the vacuum as non empty. It has zero particles but non zero energy. The quote of Laughlin is irrelevant to that claim. QFT vacuum doesn't share properties of an aether either. It's invariant. This has beside, being simply wrong as a claim, no place in an article about aether theories because it is unrelated.
It is false to suggest that general relativity does anything to reintroduce an aether into physics. General relativity adds nothing to special relativity that could be interpreted as a medium of light ("aether") - if anything it adds even more invariance than SR does (getting rid of absolute background). The section is false.
Pilot waves have also nothing to do with a medium of light / absolute background the way the aether was meant. This part is just random. It appears some people have added anything and everything that's defined in every point and think that's sufficient to call it an aether, that's not the case.
Is there anyone here who has actually studied physics who can argue against these points in any way and why the section should be kept? 77.3.233.209 (talk) 12:12, 21 March 2021 (UTC)

thread_title:  Non-standard interpretations in modern physics 

message: A recent edit claims that a 1902 Rayleigh paper found a way to experimentally distinguish Lorentz ether theory from Einstein's. The web site taking this view is  I am skeptical that this Rayleigh paper has anything to do with differences between the Lorentz and Einstein theories. Neither Lorentz nor Einstein make any mention of it, as far as I know. Everyone else says that Lorentz and Einstein make the same predictions. I suggest removing the change. Roger (talk) 01:37, 4 May 2021 (UTC)
replies: text: I don't think that this is an entirely accurate characterization.  The experiment appears to have been aimed at detecting a hypothesized effect expected from the Lorentz aether theory.  Had the result been positive, it would have distinguished it from the Einstein theory.  The negative result failed to distinguish them: Einstein's theory made a definite prediction, whereas the Lorentz theory would not give definitive predictions on refractive properties, but would lead to expected effects.  Thus, it would not be valid to say that the Rayleigh experiment was unrelated.  It may be reasonable to tone down the claim to "Lorentz theory led to an expectation that ...".  —Quondum 02:27, 4 May 2021 (UTC)
replies: text: The claim is not sourced to a blog post, but to an article in Applied Optics which lays out the situation pretty clearly, and to Weyl's 1922 book. (Looking into it, however, the author of the blog post is a wiki-notable OSA Fellow, so that blog post would be an acceptable source per WP:SPS.) Whether or not Einstein or Lorentz themselves said anything about it is beside the point. (As it happens, Lorentz did, in 1904, and tried tweaking his electron theory to explain the null result.) I'd get more into debating the details of possible phrasings, but as I said over at WT:PHYS, I'm not entirely sure this article should exist. XOR'easter (talk) 02:46, 4 May 2021 (UTC)

These type of experiments refuted the initial contraction hypothesis of Fitzgerald (1889) and Lorentz (1892, 1895), related to Lorentz' 1895 electron theory that accounts for all first order aether drift experiments. As later shown by Lorentz (1904) and Larmor (1904), the full Lorentz transformation explains the null result, which conceptually can be much easier understood in terms of Einstein's special relativity. --D.H (talk) 06:43, 4 May 2021 (UTC)

message: The following passage is from the section on the Luminiferous aether:
"In 'A Dynamical Theory of the Electromagnetic Field" Maxwell showed that using a model similar to EM the medium would have 'an enormous intrinsic energy' and would necessarily have to be diminished in areas of mass. He could not 'understand in what way a medium can possess such properties' so he did not pursue it further."
This wording implies Maxwell was talking about E&M, more specifically the Aether. It seems to me that he wasn't; the link suggests he was discussing gravity. I don't know how this should be edited, does anyone have advice?
