The most significant periodicities in the terrestrial impact crater record are due to the “human–signal”: the bias of assigning integer values for the crater ages. This bias seems to have eluded the proponents and opponents of real periodicity in the occurrence of these events, as well as the theorists searching for an extraterrestrial explanation for such periodicity. The “human–signal” should...

Originally, the goal in the search for extraterrestrial intelligence (SETI) was to detect the existence of extraterrestrial life by their radio frequency (microwave) emissions [1]. More recently its scope has expanded to include the search for extraterrestrial intelligence at optical frequencies [2], and the search for extraterrestrial artifacts (SETA) in our solar system [3, 4]. This paper is ...
