Strangeness

One of the specialties of science fiction—and to some extent fantasy—is to evoke a sense of strangeness.  In dealing with the alien, the cosmic, that which is far away in space or time, SF can make us feel we are encountering something that passes the limits of our knowledge or understanding.

This isn’t as easy as it looks.

The Used and the Unusual

Since at least the original Star Wars (1977), it’s been good practice to portray a “Used Future.”  Star Wars gave us a world full of beaten-up, grimy equipment that looked as if it had been duct-taped together.  This is generally a good technique.  It adds realism.  We feel at home in a world where everything is not perfectly cleaned and aligned; it’s like where we actually live.  There’s a sense of familiarity.

One opposite to the “used future,” of course, is the kind of earlier SF movie that was full of shiny, spotless spaceships and immaculate gizmos.  But the sense of familiarity also has its own opposite:  the thrill of unfamiliarity.

One way the challenge arises is with extraterrestrials.  Suppose a story has us meeting intelligent aliens.  If they seem just like us—“rubber-forehead aliens”—they won’t be convincing.  We expect something from another world to be different.  The writer or director has to show creatures, technologies, behaviors that are unlike anything we’ve seen on Earth.

Escher: Wallpaper CaveYet these things must also be believable.  Something that simply looks random or arbitrary, like an abstract swirl of colors, won’t convince us we’re seeing a real thing at all.  How do we thread the needle between the too-familiar and the unintelligible?

Just Alien Enough

Natural laws do enforce certain constraints on physical objects.  But other characteristics are a matter of custom, design choices, or aesthetics.  To show something convincingly alien, we need to know the difference.

Alien ship from movie ArrivalSometimes a single feature can be odd enough to alert us that we’re “not in Kansas any more.”  The alien ship that appears in the movie Arrival looks strange at once, because it’s smaller at the bottom than at the top.  It looks as if it’s upside-down or sideways. Not the way we’d build, yes.  But is it physically impossible?  Nope.  The ship isn’t on the ground, balanced implausibly on a narrow end.  It’s floating in the air.  This not only frees the ship from the usual need for wheels or other supports; it also introduces a second, subtler strangeness.  When we humans land somewhere, we expect to land, to set ourselves down securely on a surface.  These folks seem quite comfortable floating just above the ground.

A classic example is Arthur C. Clarke’s Rendezvous with Rama.  A massive spacecraft—a spinning O’Neill cylinder—enters the solar system, apparently inert.  A human crew matches course to explore it before its hyperbolic orbit takes it out into interstellar space again.  The ship begins to “come alive” around them—but there’s no sign of intelligent life aboard.  The explorers find one strange and amazing feature after another.  The purpose of some becomes clear:  the long, shallow rectangular valleys turn out to be immense lights that illuminate the interior.  But they never find out the reasons for many other objects.  In the end they have to cut loose from the vessel, letting it go on its mysterious way.

(Parenthetically, I advise paying no attention at all to the dreadful sequels Gentry Lee wrote to Rama under Clarke’s direction.  They make the classic mistake of erasing the mystery without replacing it with anything at all interesting.  As with certain other sequels, the only thing for a conscientious reader to do is declare them non-canonical and pretend they never happened.)

For another Clarke treatment, remember 2001:  A Space Odyssey.  The mundane and even humdrum character of the long space voyage makes the psychedelic sequence at the end feel even weirder than it is in itself.

Sufficiently Advanced Technology

Extraterrestrials need not be involved.  Distance in time or space, and the concurrent advances in technology, can also provide a good foundation for the sense of strangeness.  (It was, after all, Clarke’s Third Law that “any sufficiently advanced technology is indistinguishable from magic.”)

Among the numerous virtues of David Brin’s Hugo-winning novel Startide Rising is that sense of entering a new and unaccountable world.  His Earthly spaceship crew of “uplifted” dolphins, with their small group of human companions, use advanced techniques that are still recognizable to us.  But they’re dealing with galactic cultures that draw on hundreds of millions of years of accumulated science.  The results can be mind-boggling.  One species, for example, travels by using a captive creature that creates portals “by the adamant power of its ego—by its refusal to concede anything at all to Reality.”  This isn’t your grandmother’s hyperdrive.

Toy stack of ringsThe body of another species, the Jophur, consists of a stack of distinct rings, like a child’s toy.  The Brothers of the Ebony Shadows employ a probability weapon that sends out “waves of uncertainty.”  The fact that these species are nonhuman is incidental to the fact that their immense background of far-advanced science lets them use techniques that seem to surpass our understanding.

For a purely human example, let’s look at Arthur C. Clarke’s The City and the Stars.  (Clarke really had the knack for this sort of thing.)  The main character, who bears the pedestrian name of Alvin, lives in Diaspar, the last city on Earth, billions of years in our future.  The city’s structure does not erode or decay; it’s maintained by “eternity circuits” according to the model held in its master computers.  The people do not die in a conventional sense.  After living for a thousand years, each individual walks back into the Hall of Creation and is dissolved—but is also retained in the memory circuits, to be rematerialized eons later.  Thus the population of the city is always changing, but the individuals continue.  And that’s only the beginning . . .

Exotic Ways of Life

Technology is one thing; behavior is another.  The City and the Stars does a terrific job of imagining how the society of Diaspar is shaped by the extraordinary conditions under which its people live.

When I read Yoon Ha Lee’s Ninefox Gambit, it was billed as ‘military science fiction’—but it’s nothing like the general run of military SF.  The six factions in the story make use of technologies that create real-world effects based on “formations” of people and their consensus beliefs.  Much of the plot revolves around a revolt based on “calendrical heresy”—which is just what it sounds like:  deviation from the standard calendars.  In Lee’s world, calendrical uniformity isn’t just a matter of convenience, but of crucial importance.  The resulting society is correspondingly peculiar.  Reading the story makes you feel as if you’re constantly being knocked sideways.

Greg Bear’s City at the End of Time combines present-day characters with those living in a city one hundred trillion years in the future.  The far-future people consist of “noötic” or virtual mass, are defended by “reality generators,” and are trying to fight a cosmic entity that’s trying to destroy the universe by disintegrating its history, acting backward through time.  The present-day people in mundane Seattle keep us grounded, but trying to understand the end-of-time characters and what they are doing requires a constant stretching of the imagination.

Strangeness and Wonder

The sense of strangeness or mystery is one form of the “sense of wonder” often used to characterize science fiction.  It takes us out of the mundane, makes us strain to conceive the inconceivable.  We’re often told that world travel expands our horizons by exposing us to different places and cultures.  Science fiction goes further:  it exposes us to ideas and places and people that don’t exist in the world at all.  At its limits, SF seeks to show us more than we can even comprehend.  The lack of reality is compensated by the greater impetus to go beyond our mental limitations.

To achieve that experience, we seem to need the right combination of the familiar and the exotic.  The weird stuff at the end of 2001 isn’t entirely successful, in my view:  it’s too strange.  Not only do we not understand what’s happening; we don’t quite feel there is anything to understand.  You have to read the book to figure out what’s going on.

But when we have enough groundedness to effect the “willing suspension of disbelief,” yet enough mystery to defeat (in part) our attempt to understand, the combination is uniquely fascinating.  As I noted at the beginning, this isn’t an easy balance to strike.  But the payoff makes it worth attempting.

How Large Is Your World?

Perceived distance

A story may tell you it covers vast distances—but the reader’s or viewer’s experience doesn’t always bear that out.

Star Wars, for example, opens with the announcement that we’re in “a galaxy far, far away,” leading us to expect events on an immense galactic scale.  And of course the story does involve travel among numerous star systems.

Yet to me, at least, the Star Wars galaxy feels so small as to be almost cozy.  It never seems to take more than a day or two to get from one planet to another.  (Often the trips are made in X-wing fighters or other ships that don’t even seem to be large enough for a bathroom.)  In The Force Awakens, we even have weapons on one planet targeting other planets, as if they were right next door.  We may be instructed that the beam is traversing vast distances via hyperspace—but there’s no visceral sense of great expanses.

This situation isn’t limited to visual media.  I recently read Yoon Ha Lee’s Ninefox Gambit, which has been billed as a space opera—a category that suggests vast scope.  Yet almost all the story’s action takes place within a couple of spacecraft or space stations, lending an almost claustrophobic feel to the tale.  On the other hand, the movie 2001:  A Space Odyssey devotes a good deal of time to communicating a sense of the vastness of space.

In contrast to these surprisingly pocket-size space adventures, consider a fantasy like The Lord of the Rings.  To my mind, Tolkien’s epic does suggest great distances and broad landscapes.  But the actual distances involved are infinitesimal on a Star Wars scale.  Middle-Earth is about the same size as western Europe.  The Millennium Falcon could traverse the whole expanse from the Shire to Mordor in seconds (even without hyperdrive).  But Tolkien’s world feels bigger.  By the time we get to the end of it, we feel as if we’ve been on a journey.

Map of Middle-Earth

The same is true of most high fantasies, which at most work on a continental scale, given their technologies.  Paradoxically, the low-tech locales seem to be better at giving us a sense of epic scope.  Why?

Getting there is half the challenge

The most important factor, I think, is travel time.  We experience distances not in terms of their metric size, but in terms of how long it takes for us to cross them.  This is the sense in which technology has “made the world smaller.”

Tolkien’s world seems large because we cross it, with the characters, on foot.  All that walking!  (It’s not for nothing that the Fellowship is sometimes referred to as the “Nine Walkers.”)  This means that it takes weeks to get anywhere.  Frodo and Sam leave the Shire on September 23 and arrive at Mount Doom on March 24, a six-month journey—albeit with some stops along the way.

Strictly speaking, this factor may be time-relative-to-lifespan, rather than days or years directly.  A six-month trip would be brief for the star-traveling characters in Blish’s Cities in Flight stories; they live for centuries.  It bulks much larger in our own lives.

A related factor is difficulty.  A journey may take a long time, not just because our transportation is slow, but also because we have to grapple with trouble on the way.  Even an uneventful sea voyage from, say, England to America in the 1700s might take seven weeks on average.  But the dangers of storms, limited food and water, and being becalmed made the trip more daunting.  One didn’t do it casually.

Oregon Trail game, coverSimilarly, the wagon trains of the American West took the settlers through unknown countries full of dangers and delays.  (Recall that Star Trek was originally sold to studios as a “wagon train to the stars.”)  Even aside from the sheer travel time, these perils made the journey a more formidable challenge.  Anyone remember playing “The Oregon Trail”?  It wasn’t easy to survive the strenuous 2,170-mile trip.

The spice of travel

The wagon-train trek illustrates a third factor.  Variety in the places we pass through also makes a trip more consequential.  An Atlantic crossing might be relatively boring, aside from the weather, if you’re not on the Titanic.  But the different kinds of places we experience on the way—terrains, climates, habitations, cultures—also helps give us a sense of distance, of having come a long way.

To some extent this depends on the unfamiliarity of far places.  If another locale has the same chain stores, the same advertisements, the same customs and fashions, we’ll hardly feel as if we’ve gone anywhere.  Passing through a series of identical places will not give us the sense of transition that we gain from different environments.  But as Tolkien’s heroes traverse the Old Forest, the Barrow-downs, Bree, the Wilderlands, Rivendell, Moria, the Anduin . . .  we feel they’ve really traveled.

This unfamiliarity is itself a function of travel time and difficulty.  If it’s hard to get somewhere, not many people in my area will have been there, or know much about it.  Technology also plays a subtler role here.  If we don’t have the technology for recordings—photos, audio, video—then we are dependent on travelers’ tales, less vivid and less exact.  On the other hand, if we’ve immersed ourselves in the imagery and culture of, say, Japan before we visit, the culture shock will be less.  This is another way advanced technology makes the world smaller.

Star Wars universe mapIn a similar way, the different environments we meet on Star Wars planets do provide some sense of genuine travel—though the fact that each planet seems to have a single climate and terrain makes this variety less effective than it might be.

Taken together, the difficulty and variety factors suggest that the number of incidents on an expedition contribute a lot to our sense of size.  A very long trip may seem trivial if nothing happens.  But a quite brief excursion can seem extensive if it’s packed with important occurrences.

Generation ships, inside and out

The generation ship, of which we’ve spoken before, provides an interesting example of both types of journey.  Externally, such a vessel covers vast distances—and taking generations to make a voyage is certainly one way to make the reader feel the distance involved.  But the voyage typically proceeds with very little external change:  the ship bores on through space, for years on end.  If events within the ship are not described, the reader or viewer may not gain much sense of distance.  If the people on board are in suspended animation, there won’t be much sense of time or distance at all.  In the 2016 movie Passengers, for example, it’s only once something goes wrong that the story begins.  (Once it does, the passage of time for the characters who are awake is a major plot element.)

On the other hand, internally, the world-ship itself may seem a vast environment to the inhabitants.  This is especially true if events have deprived the inhabitants of any high-tech means of travel from place to place within the ship.  A long journey or quest inside the traveling world may thus be a major plot element, as we saw in The Star Seekers or Non-Stop.  Here, again, it’s essential that the characters encounter different cultures or locales within the ship if the reader is to have a sense of scale.

Epic scope

To create a story with epic scope, as in space opera or high fantasy, it’s useful to keep this size issue in mind.  If you want to write an epic, make sure you give it room to breathe.  If that sense of scale is lacking, our grand, sweeping conflict may come across looking like a mere tempest in a teapot.
