I have a question... and this is probably a stupid question, but... does anyone know if there is any theory to support the idea that sufficiently advanced civilizations rely on something other than radio waves or light to perform communications? My dumbass-self wonders about quantum entanglement or teleportation as means of communication we have yet to master; may be, the medium of communications for the super civilizations of the universe.
Note: Just wanted to say, I'm less trying to talk about "FTL" and more so that we may just not be able to intercept, decode, or "see" the communications via our current technologies.

P.S. Thanks for the thoughtful replies.
