Comic books are obsessed with peering into the future. Usually the results aren't particularly cheery - as in the post-apocalyptic world seen in the classic X-Men tale Days of Future Past, which serves as inspiration for the latest mutant film - because, well, a shiny happy future wouldn't make for much of a story. Thankfully, when comic books get all Nostradamus about the real world, they tend to be a little bit cheerier. Sometimes, anyway. Over the course of human history comic books have prefigured great technological discoveries, epoch-changing inventions and cultural trends. But they've also foreshadowed natural disasters and other traumatic world events within their four-colour pages in a eerie manner, making us wonder if the writers and artists knew something we didn't know. Or they were just tapping into the collective consciousness to give some dudes in spandex something fun to fight. There are predictions that came true decades later, when we finally caught up to the superheroes; predictions that happened weeks before, or even days; and predictions which weren't so much foresight as accidentally spilling state secrets. Here are fifteen times comics looked into the crystal ball, resisted the urge to throw it at a supervillain, and gave us a look into our future.
