SUMMARY

The Sagnac experiment demonstrates the effects of rotation on the propagation of light, supporting Einstein's postulate that the velocity of light is constant in all inertial frames. This experiment is often cited in debates between proponents of relativity and aether theories. The discussion highlights the significance of the Sagnac effect in understanding relativistic physics without dismissing Einstein's theories. The best resource mentioned is "Reflections on Relativity/The Sagnac Effect," which provides insights without rejecting relativity.

PREREQUISITES
  • Understanding of Einstein's theory of relativity
  • Familiarity with the Sagnac effect
  • Basic knowledge of light propagation principles
  • Awareness of aether theories and their historical context
NEXT STEPS
  • Study the Sagnac experiment in detail, focusing on its implications for light speed constancy
  • Explore Einstein's postulates in the context of special relativity
  • Investigate the historical debate between relativity and aether theories
  • Read "Reflections on Relativity/The Sagnac Effect" for a comprehensive analysis
USEFUL FOR

Students of physics, educators in relativity, and anyone interested in the foundational debates surrounding light propagation and the Sagnac effect.

Is there anyone here that can explain this phenomena using Einsteins postulat that the velocity of light is constant?
I haven't found any explanation to the phenomena on the Internet.

The Sagnac experiment appears to be a favorite case among the CON-relativity and PRO-aether folks (the two groups are not entirely overlapping). The following is the best discussion of it I found that doesn't conclude with relativity-is-wrong. I don't know who wrote it.
