Why the universe might be hiding its loudest voices from usFor decades, SETI has scanned the cosmos for sharp, distinct radio spikes—the ultimate technological fingerprint. But new research suggests we might be looking for the wrong thing…- The hunt for alien intelligence began with a single radio telescopeWe are scanning the cosmos for signs of life, but our search is rooted in a specific technological assumption. Because we use electricity and electronics to communicate, SETI oper…
Why we might be looking for aliens in the wrong placesFor decades, our search for extraterrestrial intelligence has focused on a specific 'quiet' zone of the radio spectrum. However, new research suggests that by ignoring higher freq…
