Null Island is located at 0°N 0°E, where the prime meridian and the equator cross. The location is marked by a buoy in the Atlantic. This hypothetical place exists only in mathematics and cartography: it was created so that other places could be indexed on a map. At a weather station in Antarctica, a scientist and a robot talk to each other. We follow the scientist’s perception of a strange phenomenon that appears in the polar landscape: a metallic sphere that cannot be captured by cameras and is visible only to the organic eyes of humans and animals. The robot – a form of artificial intelligence that controls the cameras and has been living there for a long time – cannot detect the sphere and this disagreement about what is being seen triggers more subjective and existential conversations between scientist and robot.
