Meet John Titor
John Titor first appeared on the internet in the year 2000. He left mysterious posts claiming to be a time traveler from the year 2036. His time travel mission was to go back to 1975 to pick up an IBM 5100 computer. He then decided to stop in 2000 for “personal reasons.” John Titor posted a picture of his time machine to prove he was a real-time traveler. The picture could not be reverse searched or found anywhere else on the internet or in general.

One of John’s predictions for the future was that in 2004, a war would begin in the United States. This war would turn into a World War ultimately, killing millions of people. As we know, that prediction didn’t come true. However, John had a few accurate predictions, including the Columbia space shuttle disaster and information about black holes that were later verified by the one and only Steven Hawking.
