SUMMARY

The discussion centers on the assertion that photons only exist during emission and absorption events, with no evidence supporting their existence in the electromagnetic (EM) field when not interacting with matter. Participants argue that this perspective, rooted in quantum electrodynamics (QED), challenges traditional notions of existence in physics. Key points include the idea that photons cannot be measured outside of these events and the implications of this view on understanding quantum behavior. The conversation highlights the philosophical implications of measurement in physics and the nature of reality as perceived through quantum phenomena.

PREREQUISITES
  • Understanding of quantum electrodynamics (QED)
  • Familiarity with the concepts of photon emission and absorption
  • Knowledge of electromagnetic (EM) fields and their interactions with matter
  • Basic principles of quantum mechanics and measurement theory
NEXT STEPS
  • Explore the implications of quantum electrodynamics (QED) on photon existence
  • Research the role of measurement in quantum mechanics and its philosophical ramifications
  • Investigate experimental techniques for indirect photon detection, such as cavity quantum electrodynamics
  • Study the concept of wave-particle duality in the context of coherent photon states
USEFUL FOR

Physicists, quantum mechanics enthusiasts, and philosophers of science interested in the nature of photons and the implications of measurement in quantum theory.

I think photons only exist in the dimension of time(both proper and relativistic) while in transit.
