The SETI project scientists are known for tracking possible extraterrestrial signals, but now they are also considering sending messages from Earth telling of our position. A researcher from the University of Cdiz (Spain) questions this idea in view of the results from a survey taken by students, revealing the general level of ignorance about the cosmos and the influence of religion when tackling these matters.
The Search for ExtraTerrestrial Intelligence (SETI) project is an initiative that began in the 70s with funding from NASA, but that has evolved towards the collaboration of millions of Internet users for the processing of data from the Arecibo Observatory (Puerto Rico), where space tracking is carried out.
Now the members of this controversial project are trying to go further and not only search for extraterrestrial signs, but also actively send messages from Earth (Active SETI) to detect possible extraterrestrial civilisations. Astrophysicists, such as Stephen Hawking, have already warned of the risk that this implies for humanity, since it could favour the arrival of beings with more advanced technology and dubious intentions.
The ethical and sociological implications of this proposal have been analysed by the neuro-psychologist Gabriel G. de la Torre, professor at the University of Cdiz and participant in previous projects such as Mars 500 or space psychology topical team project financed by the European Space Agency, who wonders: "Can such a decision be taken on behalf of the whole planet? What would happen if it was successful and 'someone' received our signal? Are we prepared for this type of contact?"
To answer these questions, the professor sent a questionnaire to 116 American, Italian and Spanish university students. The survey assessed their knowledge of astronomy, their level of perception of the physical environment, their opinion on the place that things occupy in the cosmos, as well as religious quest
