Over the past sixty years, the search for extraterrestrial intelligence has been ongoing, but so far, we have found no evidence of technomission from extraterrestrial civilizations. As a result, some researchers have questioned why we have not received any signal so far.
EPFL’s statistical biophysics laboratory guest scientist Dr. Claudio Grimaldi developed a model that could explain this phenomenon. According to Dr. Grimaldi, the reason we haven’t detected any technological emissions from extraterrestrial civilizations is because Earth could exist in what he refers to as void space. This means that technological emissions do not easily reach the space where Earth is located.
According to Dr. Grimaldi’s model, the existence of “technological radiation” spreads throughout our Milky Way galaxy. If the study is true, we have been in a vacuum for sixty years, but somewhere in our galaxy there are fewer than one to five electromagnetic emissions per century. This is as rare as a supernova in their Milky Way. leads to
Dr. Grimaldi suggests that the best strategy for searching for technological emissions from extraterrestrial civilizations may be to analyze data from other astrophysical studies by the SETI community. Radio emissions from other stars or galaxies must be detected to determine if they contain any techno-signals.
It started in 2015 and will continue till 2025. The Breakthrough Listen radio telescope is committed to searching for extraterrestrial intelligent civilizations. It is 50 times more sensitive than current telescopes. The project is surveying the 1 million stars closest to Earth. It even scanned the emission of 100 galaxies closest to the Milky Way.
