The term predestination paradox is used in the Star Trek franchise to mean “a time loop in which a time traveler who has gone into the past causes an event that ultimately causes the original future version of the person to go back into the past.”[16] This use of the phrase was created for a sequence in a 1996 episode of Star Trek: Deep Space Nine titled “Trials and Tribble-ations”,[17] although the phrase had been used previously to refer to belief systems such as Calvinism and some forms of Marxism that encourage followers to strive to produce certain outcomes while at the same time teaching that the outcomes are predetermined.[18] Smeenk and Morgenstern use the term “predestination paradox” to refer specifically to situations in which a time traveler goes back in time to try to prevent some event in the past, but ends up helping to cause that same event.[10][19]
