A video titled BACK TO THE FUTURE predicts 9/11" ... has been online since late July. From the video's first seconds, it seems like an obvious joke. It ticks off every box on the YouTube conspiracy-video checklist: the authoritative male voiceover; a preponderance of red circles and arrows. At 4:05, the narrator even manages to sneak in the obligatory Illuminati reference: Why, he demands, does the all-seeing eye appear on a storefront in the background of one scene for a split second? Although the video isn't entirely sincere, it's also not a parody or joke. The guys behind the video ... believe that 9/11 and "Back to the Future" - and everything in the universe, really - are connected by a vast Web of unseen, mystical, esoteric ties. This belief, dubbed "synchromysticism," has attracted a small but devoted following online. And some of its practitioners make these things called "sync films": an art form that explores the "conscious connective fabric that ties together all matter and energy within the universe." The synchromystics have also made videos implicating "Back to the Future" in everything from Roswell to JFK's assassination. "By documenting the interconnected patterns we observe, I believe we have become fractal cartographers - mapping the invisible landscapes of a quantum and/or holographic universe," writes synchromystic Alan Abbadessa-Green ... who worked on the 9/11 video. "Synchronicity serves as the compass."
