I09 wrote a cool, thought provoking post on 'Why Time Travel should be messy.' It lists the 4 basic concepts books, movies and televisions use for Time Travel. I particularly like 3 and 4, as does the blog author. The bottom line is, life is messy, so why should the elements of time travel always be wrapped up in a neat little bow with all the dots connecting together in a perfect little loop? The last few paragraphs got me thinking about Voyagers! and how they must keep history on its proper, neat, course, because somehow, inexplicably, history alters itself and the entire space-time continuum is thrown out of whack until they intervene and make things right again.
I put that one line in bold because it brings up an interesting concept for Voyagers! It's a concept I've toyed with in numerous fan-fictions. In order for history to go wrong, there must be a 'bad' Voyager who deliberately messes things up. That would be Voyager Drake. His goal is to destroy the flux of history and create a tangled web for Voyagers Headquarters. A similar thing happens in Quantum Leap, when Sam meets the 'Evil' leaper. Somehow there's a parallel universe complete with a wicked hologram and Ziggy-like computer that tries to destroy everything Sam has put right. That trope goes back to 'Good vs. Evil' and 'God vs. Satan.' But it lends strength to the blogger's argument about how the past is fine UNLESS someone makes a change. Apparently Voyagers are in a universe where the past can be changed. And so is Dr. Sam Beckett.
But just because Voyagers! likes to serve things up in a neat, tidy package and "Travel through time to help history along…" doesn't mean it's not adventurous or exciting!
