When a time traveler visits the same place more than once, copies remainNeeds Examples Description Needs Help
As described in Up the Line, by Robert Silverberg, in some versions of time travel, if the same person visits the same event more than once, duplicates of that person remain. For example, if our hypothetical time traveler goes to, say, JFK's assassination five times, somewhere in that crowd will be five instances of our time traveler. Do we already have this one?
