unexplained phenomenon
Puzzling event, unknown cause
An unexplained phenomenon is an event or occurrence that defies current understanding or scientific explanation.
UFO sightings, spontaneous combustion, and mysterious disappearances qualify as unexplained phenomena.
The phrase often carries a whiff of the paranormal, though it technically just means we don't yet know the cause: Investigators documented the unexplained phenomenon but offered no theories.
