I pose a theory that if you were to go back in time and kill your parents, you would continue to exist in that timeline. However, if you were to travel forward into your normal time you would cease to exist. (ie POOF) Documents would never exist and nobody would remember you. Impossible you say? No. Think of it this way... pyschics are able to gain information from an event they personally have never experienced. To me, it would make sense that the opposite would be true; that we can lose information from an event that we never experienced.
