Although there is debate over the exact date it started, on November 02, 2000, a person calling themselves Timetravel_0, and later John Titor, started posting on a public forum that he was a time traveler from the year 2036.
One of the first things he did was post pictures of his time machine and its operations manual. As the weeks went by, more and more people began questioning him about why he was here, the physics of time travel and his thoughts about our time. He also posted on other forums including the now non-existent Art Bell site. In his posts John Titor entertained, angered, frightened and even belittled those who engaged him in conversation.
On March 21, 2001, John Titor told us he would be leaving our and returning to 2036. After that, he was never heard from again. Speculation and investigation about who John Titor was and why he was online continues to this day.
Although it may be easy to dismiss all this as science fiction, most people who read his posts agree that there is something very haunting about John Titor and what he said. In addition, and open to more debate, he also made a series of predictions and comments that eerily seem to be coming true.
One of the last pictures John Titor posted is showing a cut-a-way of his time machine.
