5 Reasons Science Fiction Hates Actual Science

Faster-Than-Light Travel

This is the big one, the single technology which parks so much science fiction in the realm of "laser fantasy." Spaceships capable of hopping from star to star while their occupants have exciting adventures seducing and murdering aliens. Whatever the actual technology is called -- warp drives, hyperdrives, jump drives -- it always has one thing in common: It's fucking impossible. Nothing can travel faster than light. It's not a rule so much as something woven into the fabric of reality; there wouldn't be light, or a Universe, or your dumb ass in it if things could go faster than light.

The Rocketry Problem

"A-ha!" I hear some of you nerds saying, sweatily. "We don't need faster-than-light travel to tell science fiction stories!" And they're right, sweatily. There are varying degrees of "hardness" in science fiction, and there are in fact many stories which take place at slower-than-light speeds, using relatively plausible inventions like fusion engines. These take place entirely within the Solar System, or aboard slow-ass spaceships that inch across the galaxy, but that's fine. Realism, boom, another Cracked article successfully refuted. Well done, you. Hit the showers.

Cyberspace

In the hands of a competent writer, computers can do anything. In the hands of an incompetent writer, they can do quite a bit more. Fictional hackers can learn any piece of information in the world, open any door, and shut off anything, anywhere, electronic or not. Security systems, lights, a tree -- anything. This will of course all be accompanied by glowing icons and progress bars and laughing skull GIFs. And that's ignoring all the infinitely more rad possibilities when we dive into the Matrix, or cyberspace, or anyplace where a hacker might have more in common with a martial artist than the bearded database admins they are in real life.

Obviously, real-life hacking is about a million times less exciting than the way it's depicted in most works of fiction. Even if you set aside all the obviously fake stuff with UIs based on glowing cubes (which would probably be terrible to actually use), there's the simple fact that hacking often isn't done in real time. It involves a lot more painstakingly poking and prodding at a piece of software until it breaks, and then looking at the crap that falls out. Hacks are almost always developed in advance, and when deployed, rarely require fast typing or thumping electronic bass lines to work.

But Science Fiction Uses It Anyway, Because ...

We need those thumping bass lines. We need them so bad.

Fiction, and visual fiction in particular, just cannot process the act of someone working quietly at a computer. That's why science fiction has gone to such incredible lengths to make hacking look like anything else. Here's a quick test you can do if you work in an office to see the problem. Just sit there, quietly watching a co-worker tap away at their computer. Do it for six or seven days. Get weird about it. That's what hacking looks like. You can't make a movie about that.

Deflector Shields

You know how these work. The bad guys shoot at the good guys with a brightly colored whatever, and the good guys' ship shakes, and everyone on the bridge lurches in roughly the same direction. The shields are almost down! And the tension, oh boy, the tension. It's something.

Of course, there's just no conceivable way any of this makes sense. There are sort of ideas to use magnets to protect spaceships from cosmic rays, which is fine. It's just ... ooooh, cosmic rays. Hardly a Klingon bird of prey. Some students with calculators and fire in their eyes also have considered using magnets (again) to contain bubbles of plasma which could maybe do something shieldy. But it's all still very, very vague, which is why most science fiction works that have energy shields don't even try explaining how they work.

But Science Fiction Uses It Anyway, Because ...

Deflector shields let you put a character in peril without having them die. It's the same reason action movie guys keep getting shot in the shoulder, or why Rocky keeps getting punched in his face. You're hurt, but not really, so get back in there. Shields also allow for big cinematic battles with brightly lit ships wailing on each other. So much of our science fiction just kind of assumes space combat will look like dogfights, or 18th-century naval battles, or some other terrestrial combat, which just doesn't seem likely. Real-life space combat will involve a lot more asking your computer to shoot at another computer several million miles away and waiting to be told what happened. The beep on your coffee maker has a similar level of dramatic tension. You'd just sit there, existing, until you didn't, at which point you were dead and you lost.

Giant Robots

Giant robots are awesome. They can punch our enemies and kick our enemies and hold us in their arms. I love them, and you should too.

They also simply do not work.

I've talked about the square-cube law before, but it basically says that as something grows in size, it becomes heavier faster than it becomes stronger, and will eventually not be able to support its own weight. Its why elephants have a different shape than horses, why insects can fall from any height, and why office buildings so rarely fight battles for us.

Even if you get "science" to invent some new super-strong metal -- "finewhateverium" -- you'll run across a bunch of other problems. Your cooling system doesn't scale up properly, or your robot's foot sinks several meters into the ground with each step, or its heart grows so large that it can't do anything but love. As much as you might want them to work, giant robots simply don't.

But Science Fiction Uses It Anyway, Because ...

Who's going to fight Godzilla? Humans? We made Godzilla, you idiot, we're the real monsters, weren't you paying attention?

And that's basically the crux of the problem: Humans need giant robots in our fiction because humans have giant problems. And if we do succumb to the inevitability of giant robots, they need to be fake as heck. Any attempt to realistic them up will find them getting stuck in the mud, or breaking their own legs, or getting murdered easily by tanks or just some kids with a rope. Realistic giant robots suck, and it was humanity's greatest folly to even consider the idea, which means we will probably be destroyed by them. That's just how these things go.
