The Spectrum of UFOs: Identifiability, Anomalies, and Data Limits
To the point
UFOs are a broad category, ranging from birds and drones to misread planets, and there may be no single answer about what they are because the main task is separating identifiable objects from potentially truly anomalous ones, a boundary set as much by data limits as by the objects themselves.
UFOs cover a spectrum—from birds at odd angles to drones or planets mistaken for something else. I don’t know if they’re alien spaceships, but that should probably be the last hypothesis. The trouble is thinking there’s one answer to what they are when, in reality, UFOs form a category: anything personally unidentifiable in the sky. They mean different things to different people. Researchers who take the topic seriously must separate the identifiable from the potentially truly anomalous, and that threshold is the hard part. There isn’t a clear answer on whether any truly anomalous objects exist or if we simply lack enough information to identify them. The issue is as much about the limits of our data as it is about the objects themselves.
