Time travel, while perhaps one of the most interesting devices in the series, is also confusing, befuddling, and inconsistent. In the words of Captain Janeway, “the future is the past, the past is the future; it all gives me a headache.”
While we can’t get too deep into the purported mechanisms behind Trek time travel—they rely on things like “chronotons” whose nature real-world science has sadly yet to discover—it's still interesting to ponder time travel's effects. How does it affect the present? Is interference with the past a predestined part of history? Do alterations in the past get mixed into the current timeline?
