SETI: What Are We Looking For?

TL;DR

SETI searches for engineered signals in radio and optical spectra to find evidence of advanced extraterrestrial civilizations.

Transcript

you asked me what is it that we're looking for well we're looking for something that as far as we know nature can't produce so we've heard about looking for signatures of habitable worlds we've talked a little bit about looking for bio signatures on those worlds what we're doing in SETI both in the radio here which is what I work on and also in the...
