(Universe Today) – Roughly half a century ago, Cornell astronomer Frank Drake conducted Project Ozma, the first systematic SETI survey at the National Radio Astronomy Observatory in Green Bank, West Virginia. Since that time, scientists have conducted multiple surveys in the hopes of find indications of “technosignatures” – i.e. evidence of technologically-advanced life (such as radio communications).
To put it plainly, if humanity were to receive a message from an extra-terrestrial civilization right now, it would be the single-greatest event in the history of civilization. But according to a new study, such a message could also pose a serious risk to humanity. Drawing on multiple possibilities that have been explored in detail, they consider how humanity could shield itself from malicious spam and viruses.
The study, titled “Interstellar communication. IX. Message decontamination is impossible“, recently appeared online. The study was conducted by Michael Hippke, a independent scientist from the Sonneberg Observatory in Germany; and John G. Learned, a professor with the High Energy Physics Group at the University of Hawaii. Together, they examine some of the foregone conclusions about SETI and what is more likely to be the case.
