John Titor

Titor's purported military insignia John Titor and TimeTravel_0 are pseudonyms used in communications and on Internet forums between 1998 and 2001 by an individual claiming to be an American military time traveler from the year 2036. The communications appeared most prominently on the Time Travel Institute, an Internet forum dedicated to discussing time travel and fringe science since 1998. His posts discussed various aspects of time travel and described future calamitous events, including a global nuclear war that he predicted would take place in 2015.

The story fascinated Internet communities, but the increasing inaccuracy of the predictions and other inconsistencies led many to view it with skepticism and try to discover who created it. A 2009 investigation suggested that the affair was a hoax started by Larry Haber, a Florida entertainment lawyer, or one of his brothers, John Rick Haber or Morey Haber, both of whom have careers in computers and information technology. However, the Habers and other suspects have denied these reports, and no one has publicly claimed to be the originator of the Titor posts.
