In November 2000, a stranger entered aninternet discussion about time travel and told the people there that they hadalmost worked it out. He called himself TimeTravel_0. Within a few months, hewould be known as John Titor, a soldier who claimed to have come from the year2036. He said he had travelled back to 1975 to collect an old IBM computer andhad stopped on his way home. He also said that the United States was headingtowards civil war, followed by a nuclear conflict in 2015. He spoke of these eventsas memories. The people reading his posts were still fifteen years away fromthe date he gave for the nuclear attacks. Titor said he had already survivedthem. SOURCE NOTES 1.
