Scientists are rethinking the search for extraterrestrial intelligence by studying firefly bioluminescence instead of only looking for human-like radio signals. Traditional SETI efforts suffer from anthropocentric bias, assuming aliens would develop technology mirroring our own. Fireflies evolved energy-efficient, structured light signals that stand out distinctly from environmental backgrounds—offering a universal model for how any intelligent civilization might communicate. By focusing on mathematical patterns that differ from cosmic noise like pulsars, rather than specific technologies, researchers hope to detect alien signals we'd otherwise miss. This new approach using digital bioacoustics and evolutionary communication principles could help us find civilizations that transmit information in ways humans never imagined.
