SETI at the cosmic blackbody radiation peak
Abstract
Roughly two-thirds of the past 50 SETI studies have concentrated in or near the 'Water Hole' frequencies (between 18 cm and 21 cm wave-length), with no success so far. Gott (1982) proposed an alternative, namely to look at the frequency where the peak of the 2.735 K Cosmic Blackbody Radiation (CBR) is located. An update is presented here on what little has been done so far there, and on what could be done in the 1990s with current receiver technology.
