SUMMARY
The discussion centers on the nature of electromagnetic (EM) waves, specifically addressing the misconception that light can travel as a longitudinal wave. Participants clarify that oscillating charges in a vacuum create near-field effects, which do not constitute true EM waves. EM waves are definitively transverse, characterized by two polarization states, and any claim of longitudinal behavior must demonstrate three polarization states to be valid.
