Discussion Overview

The discussion revolves around the relationship between magnetic fields and electric fields, particularly how a magnetic field can generate an electric field without experiencing time, as perceived from the perspective of a photon. The conversation touches on concepts of time, reference frames, and the nature of electromagnetic fields.

Discussion Character

  • Conceptual clarification, Debate/contested

Main Points Raised

  • One participant suggests that since anything moving at the speed of light does not experience time, a photon would be emitted from one atom and instantly absorbed by another, raising questions about how magnetic fields can generate electric fields.
  • Another participant counters that discussing the reference frame of a photon is not valid, as photons do not have a reference frame, and that the oscillation occurs in the observer's reference frame.
  • A different viewpoint emphasizes that humans, unlike photons, experience time and electromagnetic fields, and that the concept of "experience" does not apply to photons due to the lack of time for them.
  • One participant notes that Einstein's definition of time as what a clock measures makes it meaningless to consider time for a photon, arguing that it does not make sense to claim that a photon experiences time instantly.

Areas of Agreement / Disagreement

Participants express differing views on the nature of time and experience for photons, with no consensus reached on how these concepts relate to the generation of electric fields by magnetic fields.

Contextual Notes

The discussion highlights limitations in understanding the relationship between time, reference frames, and electromagnetic fields, particularly regarding the implications of a photon's lack of time experience.

As I understand it anything moving at speed c doesn't experience time so from the perspective of the photon its emitted from one atom and then instantly absorbed by another.

If this is so then how does a magnetic field generate an electric field when it has no time to do so? Something that's not experiencing time shouldn't be able to oscillate.

Nature is so confusing.

You can't talk about the reference frame of a photon; it doesn't have one. The oscillation you're talking about happens in the observer's reference frame.
 
Because we are not photons - we experience time, we experience EM fields. Photons do not experience EM fields. Like you say, "experience" is not a good concept for photons because there is no time for them to experience anything. We give up and talk about world-lines in 4D.
 
Just remember, Einstein defined time as what a clock measures. Since no clock can travel at c, it's meaningless to consider time for a photon. It doesn't make sense to say that since a photon doesn't experience time, its experience of time is instantly.
