ELI5: Why do radio stations that can't receive a signal turn into static instead of silence?

Cosmic radiation, electromagnetic radiation, even lightning - your radio picks it all up, and, in the absence of a stronger radio signal, makes the sound of the background hum of the universe.  That's kind of beautiful, isn't it?  It makes me wonder why no one has popularized listening to static as a meditative exercise.
