Discussion Overview

The discussion centers around the concept of electric field contraction in space, exploring whether such phenomena have been experimentally observed. Participants reference theoretical predictions related to the behavior of electric fields in relation to charged particles, particularly in the context of relativistic effects.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant mentions a theory predicting contraction or expansion of electric fields based on the interaction between charges, specifically between protons and electrons versus electrons repelling each other.
  • Another participant questions the validity of discussing an unpublished paper and suggests that the author would be the best source for understanding its claims.
  • A reference is made to Peter Bergmann's assertion that Coulomb's law is only valid for stationary charges, implying that moving charges could lead to a more complex interaction that might involve field compression.
  • Some participants express skepticism about the ability to measure 'space contraction' directly, noting that measuring tools would also be subject to contraction.
  • There is a discussion about Kaluza-Klein theories, with one participant indicating a basic understanding but seeking more resources on the topic.
  • One participant states they have not encountered any theory or experiment that supports the idea of an electromagnetic field contracting space, referencing Einstein's treatment of gravitational fields as unique self-interacting entities.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the existence of electric field contraction or its experimental evidence. Multiple competing views and uncertainties remain regarding the theoretical implications and practical observations.

Contextual Notes

The discussion highlights limitations in available experimental evidence and the challenges in measuring phenomena related to electric fields and space contraction. There is also a noted dependency on the definitions and interpretations of the theories discussed.

I read a theory recently which, to my understanding predicted a contraction or expansion in an electric field (like the lorentz contraction) depending on the two charges involved. Has anything like this ever been expiriementally observed

Where ? Give details.

I apologize. Theory was a bad word to use. It was in a paper I was asked to look at that has not yet been published. It is not mine so I won't give to many details(the author can elaborate if he chooses). The paper predicts that the space between a proton and electron is contracted because of their attractions(and conversely the space is expanded between to electrons who repulse). It was not clear whether this happens in our 4 dimensions or some higher dimension. So I was curious if it has been observed in the usual 3+1 dimensions
 
I would think that the author of the paper would be the best source. Since it is an unpublished source it is not very reasonable to expect that anyone else will have a good understanding of its claims.
 
Peter Bergmann, a student of Einsteins, notes " ...the Coulomb law holds only if the charged bodies do not move with respect to each other...if the charged particles move relative to each other Coulombs law must be replaced by a much more complex interaction." THE RIDDLE OF GRAVITATION,1992, page 60

In other words, if space undergoes length contraction, and mass does, would not a field also "compress" along the direction of motion. seems reasonable.
 
Ok. I understand what it predicts but my question is whether that has ever been observed. Does space contract BECAUSE of an electric field if even so slightly? I don't know of any expirements that's have been done that would disprove that to a high degree of accuracy do you. I know we don't see it every day but then again we don't see a lorentz contraction every day...
 
I don't see how 'space contraction' can be measured directly. Surely the rulers, etc will also contract ?

Do you know about Kaluza-Klein theories ?

My think was if i stand in a field and you look at me do I look thinner. obviously that has some limitations now that your point it out. I have a basic understanding of kaluza-klein theories. I've found there aren't many webpages that are as good as a paper book. The later of which I can't find on the subject and I already have several books to read and on top of that school. Are there many good books on the theory?
 
I can't rcommend a book on that subject. Maybe you should concentrate on schoolwork for a while. Especially the electric field. I'm sure your teacher will be able to answer your questions.

My prior answer was a relativistic one. I misinterpreted your question...
I have never seen a theory nor experiment that postulates an electromagnetic field contracting space...Einstein treated gravitational fields as uniquely self interacting entities...via his tensor formulation ...and that largely, may completely, holds to this day...and while other formulations have been developed I don't know if any have led to any deeper insights consistent with experimental results. Likely not or we would have heard about it.
