Last week, a man named Alexander Smith claimed that he once travelled to the year 2118 as part of a top secret CIA mission.
As with all top secret CIA missions, Smith was able to share its details in a 20-minute YouTube video uploaded to ApexTV, in which he fielded a number of viewer questions on subjects including alien invasion, global warming, and artificial intelligence.
Ordinarily, you'd dismiss stories such as this one as a cautionary tale of the dangers of dabbling in hard drugs - but Smith, to his credit, was not without evidence to support his outlandish claim. He actually produced a photograph of a futuristic cityscape (which, by coincidence, looked not dissimilar to those depicted in Blade Runner).
Granted, it's probably going to take more than this to make believers of the skeptics. After Back to the Future Part II, bringing back anything less than a sports almanac and a hoverboard is always going to seem like you're not really trying.
But, at the very least, you have to concede that it's kind of intriguing. We've been fascinated by tales of alleged time travel since the moment the idea was conceived of by writers of science fiction - and one or two of them seem halfway plausible if you are prepared to disregard so-called "facts" and "logic".
