gollark: I consider light a physical thing though. You can measure it, it directly impacts physical objects, sort of thing.
gollark: To the extent that things like countries do without physically existing, sure.
gollark: They're *caused by* things in reality, as far as I know they don't actually... have some sort of physical existence outside of being stored/processed in people's brains and computers/paper/other storage.
