Movies about time travel draw out a plot where the hero has to travel through time to save the world. Whether that’s by the hero fighting a villain. Or by them stopping something from happening before it’s too late.
Inevitably the hero accidentally changes one small thing in the past. Which sets the whole world and future off into a spiral, where the hero may no longer exist.
The philosophical ramifications of this all can be a little mind-boggling.
Nonetheless movie after movie, we obsess over this idea. That if we change one thing in the past as we time travel, that it will significantly change the course of our lives in the present.
Isn’t that an interesting idea?
Yet people have trouble believing that if we changed one small thing today, that it could change the future of humanity.
