“The Cosmic Haystack” –New 8-Dimensional SETI Search Parameter: ‘Signs of Alien Life May Be Common’


A new picture of the current search for alien intelligence suggests not that SETI has failed, but that it has barely started. Astrophysicist Jason Wright and colleagues at Pennsylvania State University have characterized the 8-dimensional space that astronomers need to search for signs of alien life. They say this space is so vast that SETI searches so far have done little more than scratch the surface. This new mathematical model suggests that signs of extraterrestrial intelligence could be common, for all we know—we’ve barely begun investigating the vastness where they might lie.
