Abstract

SETI scientists have done this by looking for the equivalent of television signals that might emanate from the planet of a civilization that uses radio-wave broadcasts as we do. They have found no evidence of the equivalent of our radio/TV signals in our galactic neighborhood, but that result is inconclusive. Galactic civilizations may be so different or so far ahead of us that they don't use radio waves to communicate. Or perhaps it's just that TV-watching is incompatible with advanced intelligence
