Hello . I believe this is the first time for you people to meet me . But believe me . I have met you all numerous time . Yes . Enough about it . I come from the same timeline as John Titor . The year 2045 . He was tasked to retrieve the IBM5100 and passed it on to someone , but somehow he stops at the year 2000 and to make matter worse , he interacted with his 3 years old self . Thus creating a time paradox where , Titor were never been to the year 1975 and never retrieve the IBM5100 . And also changing the future . His last message , proved to us that he failed in the mission that he was tasked to do .
You should get to know the story better before you start attempting to ride the coat tails of said story.
Titor traveled back in time in that hot little red sportser. To the year 1975. To retrieve a certain kind of computer but only after some modifications involving him and his grand pa. Taking the modified computer back to his time Titor hopes to bring them a legacy fix/patch to the unix 2038 bug.
While in 1975 something compelled titor to travel forward to visit 1999/2000. I personally think it was his grand pa that insisted he visit that point in time to see the results of his interactions and what effect they may have on Titors parents, but that is only my speculation. At any rate when it was all said and done he explained how he would travel back to a nearly identical timeline (with in .02 percent divergence) by going in reverse and then heading forward.
Titor also explained in his story that thier is no paradox just infinite world lines. Although you can travel to different times and spaces on worldlines the actions on one world line only effects that worldline and not other worldlines, Every universe is only affecting itself thus negating any possibility of paradox.
