Guest Editorial , May 2006 . Transforming SETI to METI . ... Those who propose, or oppose, sending Messages to Extra-Terrestrial Intelligence (METI) must contemplate the Hamlet-like question: "To send or not to send?" The science known as SETI deals with searching for messages from aliens. ... We therefore propose that, for solution to the various current METI problems, we consider transforming the familiar SETI search space to a METI search space. ... Where to search? ... When to search? ...
