The Horizon Effect
The cognitive shift that occurs when human space colonists transition from viewing an alien celestial body as an astronomical object ("a planet") to perceiving it as their immediate, mundane reality ("the world"), completely removing astronomy from their casual day-to-day lives. Characterized by the abandonment of planetary identifiers (e.g., dropping the word "Martian") and the replacement of grand geological names ("olympus mons") with hyper-local, casual shorthand (e.g. giving a random boulder a casual name like "Rocky the Boulder") based entirely on the observer's immediate physical horizon.
Person A: "Can you believe we are standing on the surface of Kepler-186f, looking out at a red dwarf star?"
Person B: "Dude, shut up and pass the wrench. The atmospheric seal on the greenhouse is leaking again. The Horizon Effect is hitting you late."
