Very few time-travel stories allow for both a self-consistent single universe and unlimited time-travel. That would almost invariably be an instant victory condition for the time-traveler, and likely boring to read about. That\u2019s why we need restrictions like only six uses per day. Interestingly, there was a movie nearly a quarter century ago that belied it\u2019s understanding of this with its silly premise.<\/p>\n
It\u2019s possible some younger readers\/listeners haven\u2019t seen this movie, so I\u2019m going to fully endorse Bill & Ted\u2019s Excellent Adventure<\/a>. It is in my top-five movies to watch when you just want to watch a plain ol\u2019 fun movie. It\u00a0doesn’t\u00a0take its subject matter seriously, but it is a damn fun time! And it has the advantage of carrying a very humanistic message.<\/p>\n It is notable in that, like the Harry Potter universe, causality points both ways (present effects having future causes). This makes for a great break-out-of-jail scene once the protagonists realize they are very nearly gods. They never use this power for anything important (it is a goofy comedy, after all) but it\u2019s a fun introduction to the self-consistency principle.<\/p>\n","protected":false},"excerpt":{"rendered":" Very few time-travel stories allow for both a self-consistent single universe and unlimited time-travel.
