So if you pay attention to movies that come out on weekends, you may have heard about this movie called Source Code which came out this weekend. Based on the title of the film, one might assume that it's about a hacker who beats a Hollywood writer to death with a UPS for not understand how computers work. But as much as that would be both breathtaking and Oscar-winning, that doesn't turn out to be the case here. Instead, Source Code deals with a man who, with the help of some experimental military technology, has to repeatedly live the same eight minutes again and again until a train stops exploding. Without spoiling the film too much, the hero does eventually succeed, saving both the train and the attractive woman whom he'd been flirting with, who unfortunately goes on to be the next Hitler. This is also as good a time as any to mention that I haven't seen the film. Because a lot of Cracked readers are involved with experimental military technology or thinking of getting involved with experimental military technology, we thought it best to compile the following list of ideas for how to get out of a similar loop in the fabric of the universe. Hopefully these will be of some use to you the next time you find yourself tumbling backwards, end over end, down the up escalator of time.
