Chrononaut hypothesis (Ufology)

The chrononaut hypothesis (from Greek: χρόνος, khrónos ["time"] + ναύτης, naútēs ["sailor, seaman, navigator"]; hence, "sailor of time", similar to astronaut, cosmonaut, psychonaut) is a position in ufology that proposes UFOs constitute contact with beings that are, relative to the contactee, originally from either the future or the past and who have travelled, physically or psychically, through time-space to the point in time where the contact was made.
