Time Travel in Modern Fiction

Part 1: The Bad Science of It

      It seems that we are in the center of a recent deluge of written and film fiction that relies on time travel as the basis, or hook to the story. “A Shortcut in Time”, the film “The Butterfly Effect”, “The Time Traveler’s Wife”, by Audrey Niffennegger”, the film “Kate and Leopold”, and many others all draw in the reader or the filmgoer with the originally Victorian fancy of being able to visit the past, possibly changing the order or nature of the way things happened, or by traveling to the future for an early-bird view of things to come. This prospect, of course, has its natural attraction: what a thrill it would be to be able to travel back to the ancient Middle East and watch, for example, the birth of Christ, or to confront the crew of the Titanic, trying to avert the disaster, or to visit one month, or one week in the future for racetrack results, and scores of sporting events. More romantic notions include a trip to the past to unravel mistakes that led to loss of a loved one, or to construct a new pathway for relationships to better flourish.

     These are romantic and adventurous notions indeed, but they are also rooted in the foundation of a sandy marsh. (Note: this is where the discussion usually begins to deliver or cause a severe headache, so be prepared with your pain reliever of choice before reading further) Let’s take the grandfather of time travel novels as an example of this slippery slope: “The Time Machine”, by H.G. Wells. If you haven’t read it, you have certainly heard of it, or have seen one or both of the films. In “The Time Machine”, the Time Traveler moves through time while seated in a wondrous machine of his own creation. He is able to travel both forward and backward in time, or to the past or future, with his present being the starting point. And Wells makes a point of emphasizing that the Time Traveler is moving only through time, that is to his past or future, and is not traveling though space. This is a vital distinction. Remember that the Time Traveler starts and ends his journey from a fixed site in London; he does not, for example, send himself into the future and reappear in Paris. The machine can move only along the pathways of time, that is, according to Wells, and practically every other author who dares to attempt a time travel story. The problem with this proposition, however, is that it is not rooted in any branch of science, and this is supposed to be, in fact, science fiction.

     In “The Time Machine”, the Time Traveler watches the world around him change as he sits in his contraption inside his laboratory in London and propels himself into the future. The reader (or filmgoer) watches as the trees shed their leaves, season after season changes, the years rocket by, and yet the actual physical position or the Time Traveler and his machine do not change; they are as affixed to the site from which they began, thus underscoring the author’s theory that the Time Traveler moves only through time, and not through space. But is this theory correctly underscored by this example?

      Remember that while you appear to be sitting in your chair, quite still, reading from your computer screen, you are actually in motion. The Earth, after all, is spinning, one complete rotation each 24 hours. And the Earth itself is also rotating around the Sun, one complete rotation every 365 days or so. Because of this, the physical space that you occupy in you chair near your computer screen is changing, or shifting in space, even if you never leave your chair. So that, if you really had a time machine, and traveled from your bedroom to fifty years into the future (or the past for that matter), your arrival destination would be different, relative to the rest of the world around you, than when you left on your journey. So you may appear across the street in the neighbor’s driveway, or actually appear several hundred feet above (or below) the ground. See the way it would really work if we could travel through time? (See; I told you the headache would start)

    So what does this mean? Simply that most time travel stories are based upon bad science. That doesn’t make them bad stories, just harder to deal with once you start to really think about them.
