Before radios were invented, have there always been radio waves floating everywhere in the air? Just waiting to be harnessed and used for a purpose? (lemmy.world)

Actually, yeah. But not in a way that we are harnessing or anything, more in that radio signals are also generated by stellar bodies and phenomena like stars, black holes, etc. The first time anyone ever turned a radio on, they got static which they didn't expect. That static is just cosmic radiation.
