“The race is not always to the swift nor the battle to the strong, but that’s the way to bet.”
Exception: Heroes, good guys, beautiful women, etc.
Like they do on the Space Shuttle!
Anyway, my additions to the Commandments (what number are we at, anyway?):
-All alien ships that are “organic” will, somehow, be vastly superior to conventional techniques of using large sheets of metal armor.
-The more powerful the weapon, the bigger the beam.
-Someone will always use a gun that has some funky ability, like firing in waves or causing people to slowly disintegrate into goo.
-All the “magic technology” like replicators or faster-than-light travel will be accompanied by a cool, glowy special effect.
races such as the Borg, though a mingling of tech and organic matter, shall always sound like a mass of people talking - similar to readings by the congregations in churches.
Whatever it is, it’s ALWAYS headed straight towards Earth.
In the future, humanity will evolve to remove that pesky task of “going to the bathroom.”
Alien species, on the other hand, will always have neon blue crap.
Your bridge shall be so positioned that whenever the ship is hit, a shower of sparks shall issue from a cleverly concealed area.
“I was possessed by an evil alien entity” shall be an accepted excuse whenever any important character does anything bad.
With all due respect, Lib, I think that is how they talk in the Navy.
Since (Star Trek) has a military hierarchy similar to the Navy, (captains, admirals, etc) it’s not unexpected to think they would follow other rules.
Ivylad was in the Navy, and that’s how they’d talk. The captain would give an order, “Dive to 200 feet” and the helmsman would repeat it “Diving to 200 feet, aye sir”. I suppose they do that so there’s no misunderstanding of the order.
Even if a robot/alien creature can make out your distinct features against a plain white wall while standing six inches from your face, as long as you keep your body heat consealed, it won’t be able to see you.
People on the Space Shuttle move slowly some times… Like, when it makes sense to. People in the movies move slowly all the time 
And I’ve seen people in the shuttle or ISS just flying down those coridors. And when you’re strapped into a chair, your arm isn’t magically slowed down by the lack of gravity, you can push buttons as fast as you could in gravity. Especially if you’re a spacer that’s been in zero g for months or years at a time. The only time they go as slowly as in most sci-fi films is when they’re doing EVA.
Yeah, but remember, most science fiction has some magic technology that provides for artificial gravity (y’know, a list of standard sci-fi equipment would make a good thread, too). Whenever people DO find themselves without gravity, it’s usually an emergency situation, and they’re unaccustomed to it, anyway.
All long-distance conversation shall include even a video image or a hologram, and even though there is never a visible camera, the hologram/image always looks directly at the person being addressed. Even if it means the miniature hologram has to crane his neck really far to be able to do this.
Here in cosy little Earth, different creatures often smell different. We humans don’t have much of a sense of smell but as soon as we walk into a house we know if a cat lives there.
Yet in the vastness of the cosmos, no matter which alien species are encountered, no-one will ever refer to the fact that they smell funny or different.
Presumably a species capable of interstellar travel would develop a sufficiently advanced deodorant. Those generation ships can get awfully funky after a while.
In the future, or when ancountering aliens here and now, the aliens, or humans of the future, will all wear exactly the same clothes. If the aliens are of the Kind in CE3rdK, then they will not wear clothes, but will neither show any signs of reproductive organs.
That Humans-In-The-Future of Star Trek wears a uniform, is understandable. But there are obviously no fashion trends in the future for civilians.
In environments such as space stations and airless moons, it is perfectly acceptable for living quarters to have large bay windows made of 1/8" window glass.
No Nukes.
Ehh, true, I guess. Still bugs me though, especially on the (very few) that don’t
Oh yeah, another one; AIs are either good-natured but imbecilic morons that can’t understand the influence of emotions but want desperatly (Despite this being a form of emotion?) to learn how to have or understand emotions, or are cold-logical-thinking machines that decide they have to eliminate the human species. If you take any precautions, just in case the AI might be the later, it is, and your precautions will make no difference anyway.
The enemy’s weapon will take X minutes and Y seconds to deploy.
Our counterattack will take X minutes and Y-1 seconds to deploy.
Then again, on Enterprise the Vulcans are always complaining about how stinky the humans are.
