Discussion Overview

The discussion revolves around the analogy of a photon as a phonon within the concept of ether, exploring the implications of this analogy for understanding the dual nature of light as both a particle and a wave. Participants engage with historical and theoretical perspectives, questioning the validity and applicability of the ether concept in light of modern physics, particularly special relativity and quantum mechanics.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • Some participants propose that a photon can be analogized to a phonon, suggesting that both can be viewed as particles or waves depending on perspective.
  • Others question how the proposed ether could be detected while conforming to established experimental evidence and the theory of special relativity.
  • Some argue that the ether concept has not been disproven but is considered unnecessary by many physicists, citing Occam's razor.
  • A participant challenges the assertion that the Michelson-Morley experiment disproves the ether, suggesting that it only failed to measure it.
  • There is a discussion about the quantum nature of light and the challenges of explaining it as a vibration in a medium, with references to phenomena like particle pair production.
  • Some participants express skepticism about the validity of ether theories and emphasize the importance of experimental evidence in supporting physical concepts.
  • There are mentions of the complexities involved in particle interactions, such as the creation of fermions from bosons and the implications for understanding light and matter.

Areas of Agreement / Disagreement

The discussion features multiple competing views regarding the validity of the ether concept and its implications for understanding light. There is no consensus on whether the analogy of a photon as a phonon is useful or accurate, and participants express differing opinions on the relevance of historical ether theories in modern physics.

Contextual Notes

Participants note the lack of experimental evidence supporting the ether concept, while also acknowledging that some proposed ether models may possess properties that make them undetectable. The discussion highlights the complexities of reconciling classical and quantum perspectives on light.

Who May Find This Useful

This discussion may be of interest to those exploring the nature of light, the historical context of ether theories, and the implications of quantum mechanics on classical physics concepts.

Hi everyone,

I've been doing some good old thinking about the photon, and how it is a particle/wave etc, and kind of came up with an analogy that kind of works for me, and was wondering if it was applicable. I kind of related it to the idea of a phonon, as a phonon can be considered a particle or a wave, depending how you look at it (am i right...?). I then went back in history and pulled up the idea of ether. Then simply imagine that a photon is a bit of energy traveling through this ether as a phonon...could this not possibly work? It explains wave and particle behaviour...

I'm pretty chuffed at my idea but I'm 100% certain it's wrong as surely someone else would have considered it before (well they did didn't they =). But can anyone give me an indication of why it is wrong? Can I still use it as a useful analogy or not...

Thanks anyways,

Kcodon

I'm not going to tell you whether you are wrong. I would simply ask you this: how does one detect this aether you are proposing while conforming to all the experimental evidence to-date and the well established theory of special relativity?
 
Sorry I'm no physicist so no clue whatsoever about how to prove it, but I don't think it violates any experimental evidence that I know of...which is very little.

the aether has never been disproved, it's just unnecessary so by okham's razor most physicists decry it. just fyi
 
hmmm from where I'm sitting (thats mentally by the way) it seems it could be simpler than the whole conundrum of things I've heard...thats why I chose it

this is completely untrue, the Michelson–Morley experiment demonstrated that the idea of a luminiferous aether is false.
 
The ether isn't found and will never be found so it doesn't exist...

I'm not sure I sure why you responded to me. Just to make it clear, I didn't say the aether has been disproven (after all, how *CAN* it be *disproven* when many of them are proposed to posses properties that make them experimentally undetectable?), I am suggesting that there is a lack of experimental evidence in support of the aether, which he has to take into consideration if he wants his idea taken even half-way seriously no matter how much "simpler" his conjecture, as well as being a totally useless concept in the context of SR.

Be careful what conclusions you draw from experiments. "Michelson and Morley were not able to measure the aether" is a completely different claim from "Michelson and Morley were able to prove that there is no aether". The former is correct, the latter is false.

Hmmm ok I understand the Michelson Morley experiment, but mn4j would you mind explaining why this does not disprove aether?

mn4j, in physics we can only go on experiments and you are wrong in logic and fact. The MM experiment does rule out a classical luminiferous aether. If you are proposing a new kind of aether, you should state this clearly.

Back to the original question - there have been many attempts to re-invent light as a vibration in something, but they fail generally because of the quantum nature of light, and phenomena like particle pair production.

If we treat light as a vibration in some medium, then in the same way phonons are the quanta of vibrational modes, could we not explain the quantum nature of light? Also if you are meaning pair production I am assuming you are meaning of photons? As normal pair production could occur as the phonon/light would still provide energy...well I think. But i also looked it up, and there doesn't appear to be such a thing as anti-photons...Hmmm could someone please elaborate?

Ok i have been looking round on the net for modern ideas on aether, and found some useful links that seem to be in great support of aether and put forward rather controversial ideas. Think I will start a new thread with this, and get right to the point there,

Hi kcodon, photons are their own anti-particles, as with all Bosons. By pair production I mean for example, electron/positron pair production. Fermions can be born out of Bosons !

In the LHC at CERN, proton-antiproton collisions will produce very high energy photons which will decay into all kinds of matter. Hard to explain that as vibrations in a medium. ( Pace string theory ).

As I said there are lots of attempts - some bordering on crackpottery so be careful what you believe.
 
  • #15
Mentz114 I'm not completely comprehending what your saying about annihilation and matter forming... but that's fine...I'd need a few more books under my belt.

Oh and being your own antiparticle? Is that just semantics, just another way of saying a boson doesn't have an antiparticle...hmmm

Thanks for replying anyway,

Lol I love wikipedia myself (even though it can be edited by anyone and is often opinionated) and read that before replying to your last thread = )

That was why I couldn't see how this could not be explained by a vibration in
"aether"...as all that's really needed is energy, which I'm guessing the vibration can give...?

It needs more than energy to create fermions. There's quantum spin and charge to deal with.

String theories use vibrations in 1-D strings or 2-D branes to explain everything !

Have fun, but be careful about strange theories, and remember that QED agrees closely with experiment so throwing it out is a brave move.
 
  • #19
Ah now vibrations in 1D strings is somewhat silly...to vibrate you need to have 2D...mind you I can see what they mean too with 1D, depending how you look at it.

Ah yes fun is the plan...I'll try remain open to all theories and then make my own judgements from the evidence, though I think a lot of background reading is now in order.

Thanks Mentz114 for not telling me I'm wrong, in that ever so nice fashion,

Kcodon

Now, forth to Wikipedia!
