When it comes to atoms, language can be used only as in poetry.
The poet, too, is not nearly so concerned with describing facts
as with creating images.

SETI’s Best Chance: Find the Beacon

If we’re going to get lucky with SETI, it’s probably going to be through the reception of an interstellar beacon rather than the chance detection of an electronic emission from space. Sure, chance catches are possible, and for all we know odd receptions like the WOW! signal of 1977 might be cases in point. But we can’t confirm such signals because they’re one-shot affairs, whereas a beacon, designed to be received over interstellar distances, just might give us other options.
