Then there's gravity. It's a known fact
that the human body doesn't take kindly to long periods of low
gravity, so most space operas contend with that in a number of ways.
The use of centrifugal force to simulate gravity is canon – apart
from anything else, it's true. So the space station in 2001: A Space
Odyssey is good science. So is the cabin steward, who walks carefully
along the aisle of the shuttle in velcro-clad shoes, with her hair
tucked away in the weightless conditions. But most of us emulate the
movie makers who don't want to deal with weightlessness in their spaceship corridors and use
artificial gravity in our spaceships. The purists might not like it,
but those of us who grew up on Asimov and Star Wars are fine with
that.
Sometimes, though, there's a tendency
for readers of science fiction to accept a particular author's
version of technology and question another author's interpretation.
Take matter transfer, as used in Star Trek (as in 'Beam me up, Scotty'). I, for one, wasn't too
impressed with that as something real when I saw it on TV all those
years ago. But I've now had to accept it's possible. The same with
cloaking devices. We're on the brink of having technology which can
hide an object from radar emissions.
Which leads me to spaceship 'shields'.
It's generally understood that exposure to cosmic radiation would
quickly kill a human. Our atmosphere protects us from harm on the
planet's surface, but what we would use for spaceships is unclear.
But let's say we have such a shield. The canon is that the shield
protects a ship from bombardment, as well as cosmic rays. Can one
fire through the shield? Some authors say yes, others say no, and yet
others avoid the issue. If the answer is no, then the shields must be
dropped to fire at the enemy. Or maybe only a certain amount of the
shield needs to be dropped. Jack McDevitt uses that weakness in his
book A Talent for War. McDevitt also speculates that the
oft-mentioned scanner which can see through a hull and establish
who/what is in a ship isn't as simple as other authors suggest. Makes
sense to me. If you have to shield your ship from cosmic rays, would
that not also shield the ship from external scanning? Linnea Sinclair
in Hope's Folly suggests such scanning is possible. Jack
McDevitt in Slow Lightning says it's not. Most especially if
the ship is alien.
I don't know the answers. Nobody does.
All I'm really saying is that in any science fiction story the tech
has only to be true to itself in its own universe. If the reader
doesn't believe the technology, isn't convinced by the author's
argument, then so be it. But that doesn't make the technology wrong,
and comparing it to another writer's universe simply shows the
reader's own bias.
What do you think? Is there any
'technology' that you simply will not accept in a novel?
As long as the rules are consistent for that author's universe and don't break some of the basic laws of physics like gravity or vacuum in space (unless they have a believable theory for that rather than just ignoring or forgetting about it), I'm fine with whatever the author comes up with. I find it interesting that we're working on matter transference and cloaking devices, but there still isn't much of a practical theory for creating artificial gravity other than centrifugal force or velcro footware, lol.
ReplyDeleteThere are AG devices (nanotech) in all the flooring material of spaceships. Run by the main engines that also do environmentals. If the engines fail, so does the AG. (How's that?)
ReplyDeleteWe'll get there in the end. We always do.
Not exactly a technology, but intergalactic travel really pushes my buttons. (Not to anyone's surprise, because I've been pretty vocal about it.) I should clarify that I'm talking about intergalactic travel using "traditional" SF propulsion systems, not something exotic like traveling through a wormhole--or even a black hole--to be flung across the cosmos. In real space, the distances we're talking about are so incredibly immense it would take a ship over 2 million years traveling at the speed of light (which we're not sure is even possible) to reach the nearest galaxy. Galaxy-hopping is completely outside my suspension of disbelief abilities.
ReplyDeleteI have to agree, Laurie. If we're talking some osrt of hyperspace - yes, alright. But there's plenty of space in our own galaxy to keep us busy for a while.
DeleteGenerally I'm like Pippa--if the author is logical and consistent with the tech in her story, I'll go along. But glaring illogic--like using ion drive to travel to the next galaxy, as Laurie says, or shooting through a black hole without even benefit of a spaceship, as INTERSTELLAR proposed--drives me crazy. I even had to write a whole fanfic novel to explain all the stuff that was left UNEXPLAINED by the writers of STVI:GENERATIONS with their crazy Nexus. Thinking it through, Kirk couldn't be dead in some timelines, and that's the way I wrote it!
DeleteOh, yes. Interstellar. Interesting movie, but yes. Let's all pop into a black hole.
