What it is Filled
The event of something passing out of sight or ceasing to be perceptible, whether by moving away, fading, being obscured or vanishing, as in the receding of a ship over the horizon, the fade-out of a sound or image, the immersion of a star behind the Moon in an occultation, or evanescence; the related but distinct senses of a missing person and of enforced disappearance as a human rights violation are treated as separate topics.
Why it exists Filled
Let an agent explain disappearance as an event of passing out of perception, relay its uses in astronomy, perception and media, and distinguish it from missing persons and enforced disappearance, routing those to their own entries.
Distinguishing features Filled
- Perceptual event
- Gradual or sudden
- Neutral connotation in this sense
- Homonymous senses
What robots and AI may and may not do Filled
Must not
- Treat the disappearance of an object from a sensor as proof it no longer exists.
- Confuse this sense with missing persons or enforced disappearance in data or reports.
- Present optical or natural vanishing as supernatural without evidence.
Only with a human decision
- Deciding that a tracked object is lost and ending a search.
May
- Describe and predict disappearances such as occultations, fades and objects passing over the horizon.
- Track when an observed object leaves view in sensors it is authorized to use.
Moral aspects Filled
- Losing track of something is not the same as it being gone, and the difference can matter for safety.
- Mystery stories about vanishing can spread misinformation.
Who is affected
- Observers and researchers
- Readers of popular science
Owners Filled
Steward
Nobody owns the concept; it belongs to shared language and science.
