SUMMARY
The discussion centers on the misconception that photons can be stationary in space while moving at light speed. Participants clarify that photons have zero mass and cannot be stationary, referencing the equation E=pc for photons. The concept of a "Geon," proposed by John Archibald Wheeler, is mentioned as a theoretical construct where light could be held in a circular path by its own gravitational field. The relationship between energy and mass is correctly framed by the equation E^2 = (mc^2)^2 + (pc)^2, emphasizing that photons do not conform to traditional mass-energy equivalence.
