Radical Mundanity and the Silence of the Cosmos: Why Extraterrestrial Civilizations May Be Hard to Detect

Scientists believe this is the real reason aliens haven’t contacted us

Robin Corbet's radical mundanity hypothesis argues that extraterrestrial civilizations might be only modestly more advanced than humans, use technology similar to our own, and lack motivation or resources for large-scale astro-engineering or long-duration beacons, making Earth an unlikely focal point and alien invasion improbable, with any contact likely anticlimactic because faster-than-light travel or other extraordinary capabilities would be absent.
