It seems like we never get tired of time travel mechanics in TV shows and movies (well, at least it seems like I don’t). From countless Star Trek episodes to movies like Groundhog Day and the more current doppelgänger Happy Death Day, time travel provides a way to trip with the time fantastic and explore the incredible power of the do-over. But it’s hard to keep track of all the different ways time travel works in the story. Fortunately Minute Physics has made a video that does a pretty good job of explaining these mechanics in popular usage:
Of course, I have to say that I am a little disappointed that neither of Keith Laumer’s classic master works on time travel, Other Side of Time and Dinosaur Beach, were not referenced in the video, but other than that it’s a pretty cool watch.
