Planet Earth's Vanishing Act
Dr Frank Drake said the phasing out of analogue transmissions from television,
radio and radar was making our planet electronically invisible from outer
space.
"I was watching the image on my display, and it just sort of vanished.", said a spokesmonster from Tau Ceti. "Well, I wrote WOW! in the log and hypermailed my colleagues. We thought that maybe the human race had finally wiped itself out, but no such luck! No, they seem to have decided to do something about all of that pollution they were throwing out into the cosmos. You know: electromagnetic radiation."
When asked the purpose of such dumping of toxic waste, the spokesmonster replied: "Some people think it's a by-product of their primitive energy-dependent industries. One or two at the fringes of science think it's something to do with primitive communications. Of course, they get laughed at quite a lot. Humans? Communicate? They don't have the necessary body parts."
