The discussion revolves around whether electromagnetic radiation occupies space and, if so, how much volume it occupies. Participants explore the implications of radiation's interaction with gravitational forces and the concept of energy density in relation to space-time distortion.
Participants express varying views on the nature of electromagnetic radiation's occupation of space and its effects on space-time. There is no consensus on the specifics of how much volume radiation occupies or the significance of its gravitational effects.
The discussion includes assumptions about the relationship between energy, gravity, and space-time distortion, which may depend on definitions of energy density and the nature of electromagnetic fields. The implications of these relationships remain unresolved.
Atyant.E said:Anything that occupies space creates a 'distortion' to a certain degree in the space time fabric and hence will experience gravitational force.And we know radiation does experience gravitation , this would directly imply that it occupies 'space' or 'volume' . The question now is .. how much volume ?
Bill_K said:All of it. The entire universe is filled with electromagnetic radiation.
San K said:Does this mean that entire space-time gets, at least, infinitesimally distorted off an on at various points in time and space (by the radiation)?
