A Proposal for Enhancing Technosignature Search toward the Galactic Center
The Astrophysical JournalWe discuss the possibility of enhancing intelligent life searches toward the Galactic center. From the clockwork orbital motions of stars around the Sgr A* black hole, we can determine the distance to the Galactic center at an exceptional accuracy ...

Searching for extraterrestrial intelligence across a century
Journal of Physics: Conference SeriesAbstract SETI, the Search for Extraterrestrial Intelligence, is an old idea but a new science. Both inspirational and controversial, the scientific search for non-human artificial signals or communications, known as technosignatures, was pioneered by a few visionary scientists and through amazing technological advances of recent years is

CARGOISM AND SCIENTIFIC JUSTIFICATION IN THE SEARCH FOR EXTRATERRESTRIAL INTELLIGENCE
Zygon, 2019 This article compares justifications of the search for extraterrestrial intelligence (SETI) presented by scientists with ideational constructs associated with cargo cults in Melanesia. In focusing on similarities between cargoism and SETI, I argue that,
