Is the "Star trek" concept of aliens really naive?: A comment on Duric and Field

Abstract

Several assumptions used in the recent review paper on the search for extraterrestrial intelligence (SETI) by Duric and Field (2003) are critically discussed. New astrobiological results-in particular those on the age distribution of terrestrial planets-enable relaxing of some of these assumptions, which gives further justification to optimism regarding SETI projects.
