Read e-book online S.A.E.T.I.: Die Suche nach Artefakten von außerirdischen PDF

By Walter Hain

Zahlreiche Forscher, Sachbuchautoren und auch namhafte Wissenschaftler, haben sich vorwiegend im zwanzigsten Jahrhundert, im „Zeitalter der Raumfahrt“, mit der Idee von den „Göttern aus dem All“ auseinandergesetzt. Es ist eine Idee, die aus der Fachliteratur nicht mehr wegzudenken ist. Das Buch ist eine neue und aktualisierte Bestandsaufnahme zu der Frage: Waren die Götter Astronauten? Es behandelt auch verwandte Gebiete wie die UFO-Forschung und Atlantis.
Eine Suche nach Artefakten von außerirdischen Intelligenzen ist nicht a priori unwissenschaftlich. Sie reiht sich ein in die bekannte Suche nach Signalen von außerirdischen Intelligenzen, SETI. In Anlehnung daran prägte der Autor im Jahre 1992 den Begriff SAETI, die Suche nach Artefakten von außerirdischen Intelligenzen (Search for Artifacts of Extraterrestrial Intelligences).
