Four Stories Of Alleged Time Travelers

Is it possible to travel through time? Time travel could hypothetically involve moving backward in time to a moment earlier than the starting point, or forward to the future of that point without the need for the traveler to experience the intervening period (at least not at the normal rate).

Although time travel has been a common plot device in science fiction and the theories of special and general relativity allow methods for forms of one-way travel into the future via time dilation, it is currently unknown whether the laws of physics would allow time travel into the past. We may never know, but in the meantime we can at least enjoy a good laugh at those who would have us believe they've cracked the code.
