Stories for time travel are nothing new, but they never foster a good debate.

A man who just wanted to be called Noah hit the headlines this week when he claimed to be a time traveler since 2030.
He brought with him a series of predictions, in particular for the upcoming US Presidents.
Here are some famous stories from the supposed "time" travelers - read and see if you can be convinced.
John Titor's name was used in some online bulletins between the years 2000 and 2001. In his posts, Titor claimed to be an American soldier from Tampa, Florida, who was again sent as part of a government travel project.
He said one of his tasks was to get an IBM 5100 computer that he said was needed to correct some programs in 2036.
Titor was told to be on a 'ban' in 2000 to visit the family and collect lost photos in a future US civil war !.
