After decades of scanning the skies for direct calls to Earth or eavesdropping on interstellar convesations, SETI is flipping the script and changing the rules for their eponymous search for extraterrestrial intelligence. While there are many new modes of detection, it’s doubtful they outnumber the putative alien civilizations ‘out there’ yet Jon Gertner reckons detection is right ’round the corner. But If Aliens Have Visited The Solar System, Here’s How To Find Clues They Left, according to Paul Sutter. Which begs the question, “What Would Space Aliens Do With Planet Earth?” Marshall Brain lays out his vision for a benevolent invasion, where benevolent depends on one’s leanings, and plays to the trope of alien saviors. One can guess Mr. Brain’s personal leanings, but his bibliography for this piece is of interest. (CS)
