Is SETI Barking up the Wrong Tree?
Seth Shostak writes on Space.com:
It’s been 46 years since Frank Drake aimed an antenna at the stars in the first modern SETI experiment. His hope was to hear a deliberate signal – guided into space by intelligent beings – rather than the natural, noisy dance of hot electrons.More here.
Since then, SETI has expanded its search space, bettered its equipment, and refined its strategies. But the bottom line hasn’t budged: still no confirmed chitter from the cosmos.
Some people mistakenly confuse a long search with a thorough one, and figure that the lack of a SETI detection indicates that we’re alone in the Galaxy. This, however, is nonsense.
