The stability of matter: is really Maxwell wrong? (part 2).

Click For Summary

Discussion Overview

The discussion revolves around the stability of matter and the role of Maxwell's equations in explaining electromagnetic emissions from matter. Participants explore whether classical theory can account for the absence of appreciable electromagnetic emissions, particularly in systems with parts in accelerated motion. The scope includes theoretical considerations and challenges to established views in physics.

Discussion Character

  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant presents a scenario involving a large number of sinusoidal plane electromagnetic waves and suggests that the resulting emission is significantly smaller than when all signals are in phase, questioning Maxwell's ability to explain the stability of matter.
  • Another participant asserts that Maxwell cannot explain the absence of appreciable electromagnetic emission from matter and that classical theory cannot explain the stability of matter, providing a definitive "yes" to both questions posed.
  • A third participant expresses gratitude for a response but indicates that it may have been too concise, implying a need for further elaboration.
  • Another participant critiques the level of background knowledge of the original poster, suggesting that familiarity with key literature is necessary for engaging in the discussion.
  • The same participant emphasizes that concise responses are appropriate for advanced discussions, indicating that the original poster should have sufficient knowledge to understand the implications without further detail.

Areas of Agreement / Disagreement

There is disagreement regarding the ability of Maxwell's equations and classical theory to explain the stability of matter and the absence of electromagnetic emissions. Some participants assert definitive positions, while others express uncertainty or challenge the assumptions made.

Contextual Notes

Participants reference specific academic papers that may provide foundational knowledge relevant to the discussion, indicating that the conversation may depend on understanding complex theoretical frameworks.

In a previous message I have tried to show that electrical systems exist which do not generate electromagnetic waves with appreciable energy even if such systems have parts in accelerated motion.
Now I add a further example by which the meaning of what I tried to say becomes clearer.
The problem is the following: it is required to investigate the character of the electromagnetic emission resulting from a sum of a great, very great number of sinusoidal plane electromagnetic waves (with same polarization) with same amplitude, same frequency and phase uniformly distributed on the whole 360 degrees angle.
It is not difficult to imagine a physical example of source whose emission is as above described.
This time calculations were made and the result is more than clear: the resulting emission is infinitely smaller in comparison to that we have when all the signals are in phase.
The fact is quite intuitive if we help us with the method of phasors.
So my question is always the same: are we really sure that Maxwell cannot explain the absence of appreciable electromagnetic emission from matter?
Are we really sure that classical theory cannot explain the stability of matter?
I have some doubt.

Yes.

Yes.
 
Dear Drakkith,
thank you for your response, surely clear and perhaps a little too concise.

Then you have evidently not acquired the level of background knowledge that would be expected if you are going to start an "A" level (graduate level) thread on this topic. You should certainly be familiar with the classic paper on the topic by Dyson and Lenard:

https://aip.scitation.org/doi/10.1063/1.1705209

A more recent treatment is Lieb and Seiringer:

No, his answer was exactly right for an "A" level thread: the conciseness is a way of conveying to you that you should already have enough background knowledge to fill in the details for yourself. If you don't, you need to fix that before starting another thread on this topic.
