Can we convert radio waves into smaller (light) waves?
Convert radio waves by shortening them
This brought up the rectenna: a device for converting radio waves to electricity!
I may have my answer to Fermi's Paradox!
"Where is everybody?"
"Everybody is in the form of longer wavelengths - i.e, radio waves."
I might add:
"If we could somehow convert those particular radio waves, by rewinding them until they were shorter in length, they should eventually be rendered back into visible light images, should they not?"
