If someone time travels to the past, could it be that the event has already been included into the time line originally? Is the event of him travelling to the past is already in the timeline, and he couldn't change anything in the past to effect the future, no matter what? Because anything he does, there would be events that is already in the timeline that would stop him? Sorry if this is confusing but it is a very trivial question.
