May goes on, as does my analysis of science fiction. This week will focus on the center piece of the genre: the advanced technology.
Speculating on potential developments in engineering and physics has an enormous margin for error, and inevitably, some specific devices (plot or mechanical) require just as much suspension of disbelief as magic in fantasy does. That’s not a criticism, just an observation.
Consider the films that prompted my look into the genre: Star Wars. Even if the technology exists to travel at light speed, there still is a problem when it conflicts with real physics like inertia.
Imagine being in a roller coaster with your head forward, and the ride suddenly takes off, smacking your head backward. Or, driving with something heavy in the back of your car, and you brake suddenly, causing the item to slide forward. Just because the roller coaster started moving does not mean your head did, and just because your car stopped does not mean the item did.
So is the role of inertia in regular movement, and if one were in a ship traveling at light speed, they could be sent flying backwards, likely pulverizing on impact as the wall slams into them at such high velocity. Spaceballs, as campy as it is, did point out some of the realistic implications of this technology with the “Ludicrous Speed” scene. Spaceballs, of all places.
Now, the argument could be made that while originally developing light speed technology, the engineers developed a way to account for things like inertia. If modern humans accounted for the need to stop a car by inventing brakes, then it is reasonable that sci-fi technologists found similar work-arounds.
Is the physics behind Star Wars’ light speed ever explained much in the movies? No, and that is likely for the better. Otherwise, there would be more convoluted explanations that stretch the laws of nature further, breaking immersion.
And this brings me to the first main point on sci-fi technology: more realistic technology merits more explanation of how it works, and less realistic technology should receive less explanation.
A good example of this rule comes from the granddaddy of sci-fi himself, Jules Verne, and his novel 20,000 Leagues Under the Sea. Captain Nemo explains that his ship, The Nautilus, receives power from electricity. How does he do this, with the Victorian emphasis on steam locomotion? Sodium batteries. How does he get sodium? By burning coal, separating sodium from sea salt.
Boom. Sci-fi technology that operates under the laws of physics, all easily explained so that it enriches the reader’s understanding, not confuses it. Jules Verne completely predicted a new advancement that is reasonable, and has been developed decades after his book.
Another example is Arthur C. Clarke’s 2001: A Space Odyssey. As the astronaut protagonists undergo a voyage into space, their rocket has a rotating interior that simulates gravity through centripetal force. Again, a realistic discovery that uses the laws of physics as a step ladder, not a hurdle.
Returning to Star Wars, which is far more speculative and advanced than the tamer examples I gave. For the most part, this is a good example of the second half of the rule I stated: its technology is less realistic, but that is fine, because the writing in the films does not go too in-depth on how it works.
Outside sources for the Star Wars universe are a different story, and more is developed in alamanac-type books and Wikis about how it works for curious fans. But, it does not dominate the story with the physics behind it.
Another usual rule is that if a part of technology does something that is crucial to the plot, it must be explained or demonstrated. Nobody likes Deus ex Machina. Not even the Greeks, at least not anymore.
This rule applies to literature in general, and is almost like the opposite angle of Chekhov’s Gun (if a gun is set up in the story, it should be fired at some point). To illustrate, let’s call this Chekhov’s Gunfire. If a gun is going to be fired, the story should set up that there is a gun in the first place.
There is the age-old saying that rules are meant to be broken, and for me, satire can break all the rules of literature it wants. Satires of sci-fi can explain the most convoluted of inventions with whatever strange justification is needed, as suspension of disbelief is already thrown out the window. A good example is the Babel fish in Hitchhiker’s Guide, which feeds on and releases brain waves. This allows someone wearing it in their ear to understand any language.
Is that ridiculous? Of course. Can it get away with it? Of course, and the other genres just have to mope in the corner as it flouts every rule they live by.
Sci-fi’s most unique attribute can be its greatest weakness if not used correctly, and one of the best ways to prevent it from going topside is to know what to explain and when. With that, the stars are not even the limit.
What are some of your favorite sci-fi technologies? Which ones were so elegantly detailed, and which not so much?
