How Star Trek IV’s Time Travel Works

The one questionable second of doubtless altering the longer term comes when Scotty and McCoy make a take care of Plexicorp’s Dr. Nichols (Alex Henteloff) to provide the clear aluminum they should carry the whales safely into the longer term. With that materials not present within the ‘80s, Scotty principally offers Dr. Nichols the method totally free, with McCoy questioning if that is going to spoil the longer term timeline. 

Interestingly sufficient, Scotty waves it off in Star Trek IV: The Voyage Home’s cinematic incarnation, by asking his shipmate, “How do we know he didn’t invent the thing?” However, [in the film’s novelization](https://memory-alpha.fandom.com/wiki/StarTrekIV:TheVoyageHome(novel), Mr. Scott is aware of damned properly that Dr. Nichols did invent Transparent Aluminum, which implies historical past was by no means modified on this occasion because it was all the time the way in which issues have been meant to pan out. Time journey followers will acknowledge this as a “Predestination Paradox,” the place a visit in time was all the time constructed into the material of historical past to start with.
