, The starship computer can inform the crew of the impending destruction of the ship to the neareast second, but cannot use any countermeasures whatsoever- such things as cutting the fuel supply to the reactor, using sprinklers to put out the fire, or removing air from the area on fire are all apparently impossible.

, spaceships must bank in order to turn

, the engines of a space-bound ships are always needlessly located at the aft section of the craft

, Even in the 50th century, after Faster Than Light Travel and A.I. have become common technology, it doesn't seem to be possible to get a radio to work on a spaceship : radio transmission is always filled with static, screeches and sound distorsions, especially if it's a SOS or a warning message.

, Classic weapons are completely abandoned in favor of energy-beam ones, even though energy weapons are susceptible to interferences and cannot penetrate certain shields and forcefields the conventional ones could.

, The now-very-typical presence of the doomsday superweapon. First it was planets, then stars. Instead of wasting so many resources and so much manpower on the construction and deployment of such large, impractical weapons (which the destruction of such is now typically an Achilles Heel to the creators), why not use the same resources and manpower to mass-manufacture traditional weapons (and fleets of ships)that have proven to be successful in the past? I mean, imagine how many TIE Fighters and Star Destroyers the Empire could have manufactured if the Imperials hadnt built the 2 (TWO!!!) Death Stars?! The Rebellion wouldnt have stood a CHANCE! But no... planet destroying superweapons that can be slain by a single pilot in a fighter!

, All human computers must make beeps when presenting information on a screen, the horror to use a system like that and try to look at wikipedia.

, Nobody ever, ever runs out of breath, no matter what.

, Humans can visit aliens and alien planets without some kind of quarantine procedure or without the risk of giving the alien influenza or some other infectious disease, vise versa.

, Asteroids that sound like a passing jumbo jet as they pass.

, Meteors, when falling on the ground, make craters not bigger than themselves and do not damage a vast area around them. In fact, a 100-feet meteor can make a crater more than one kilometer in diameter and could easily destroy a whole middle-sized town.

, Spaceships one fourth the size of the moon have no catastrophic effects whatsoever on earth's tides or climate when they are near earth.

, In the future, all ships have artificial gravity that is just "activated" by the push of a button, with no explanation of the science behind it.

, However far the into the future a story is set, and however advanced the civilizations are, all space vessels in the era lack simple circuit breakers. An energy beam attack or sudden energy surge therefore causes computers on the ship to explode, usually only on the bridge, killing or incapacitating at least one character.

, Even though the vacuum of space has no resistance mechanism such as air or water, a starship that loses power will grind to a halt.

, Aliens have the technology to build ships that can withstand black holes, dust storms, hard landings, and cause asteroids to bounce off like Ping Pong balls. However, our oxygen seems to render them helpless, hence the number of crashed UFOs.

, Spilling a liquid on a keyboard will make a computer crash and/or explode.

, This is what I've learned from (TV)scifi about aliens and alien planets: Humans and aliens can breathe the athmospheres and eat eachothers food without problems. All planets are at (roughly) 1g and Earth median temperature, severe weather doesn't exist. All species can reproduce with eachother and no xenoracist cares. DNA is the only way to restore genetic information. Cute-looking aliens are never agressive.

, Now matter how wasteful a society is, advanced civilization never ever EVER run out of natural resources.

, Sounds in space

, Even as the ship is about to crash into a planet, nobody ever wears seatbelts

, Sensory equipment in the future combines all possible spectroscopic and medical diagnostics techniques in one handheld device. The science behind such equipment is also never explained.

, There is no question of perspective, ie an observer on a ship can view the entire black hole/galaxy/etc. The vessel is about a millimetre big whilst the object is a couple of thousand miles long in comparison. The fact that it would be impossible to see the arms of a spiral galaxy or gaping hole in space when you're practically in front of it is ignored.

, Most aliens are scary and ugly by human standards.

, Aliens are either equally strong or much stronger than humans. Much stronger is the norm.

, After having sex with innumerable females (human and otherwise) throughout the planet or galaxy, the hero has yet to pick up a venereal disease or sire a child.

, Video conferencing computer screens turn themselves off at the end of the conversation without anyone doing anything. Somehow the computer system knows what is the last thing to be said., GB

, Teleporters that operate by converting crew members from matter into energy is the same principle of vaporizing people with a ray gun. It is not teleportation, but more like replication and it violates the laws of quantum mechanics, thermodynamics and the Heisenberg Uncertainty Principle. , J.S.

, Starships that travel way beyond faster than light causes crew members to de-evolve or evolve into new lifeforms. , J.S.

, Main characters never a disfiguring scar. If they get a scar, it somehow makes them look sexier, cooler, and more rugged (Squall from Final Fantasy 8, Harry Potter from Harry Potter, Yamcha from Dragon Ball Z.) Female characters never get scars on their faces, necks, shoulders, boobs, and hands. Also, Characters who have been known to cut their wrists, never seem to have scars from previous wrist-cutting-occasions., MM

, Expensive, power-consuming beaming technology is installed in every privet bedroom/living courters of a starship and is specifically designed to in beam hot meals. What a waste of energy! It must cost a lot of power to demoleculize a plate of spaghetti and reassemble 50 meters down the hall. Not to mention it’s a waste of money. Why is it so impossible to make a breakfast order via telephone, and wait 30 minuets for a member of staff to walk down to your room from the mess hall?, MM

, People still have strong Scottish, British, Australian, Jamaican, Southern (as in the southern states in the United States of America) accents hundreds of years from now, despite none of those counties (and regions) still existing. One thing I’d like to mention is that when Hollywood became the major developer of movies and began dominating the entertainment industry, audiences- as varied as their accents may have been- began to pick up the more frequently televised “Californian Accent.” As a result, 50 years after Hollywood first started producing films, nearly all of America spoke with the same accent- with only small communities that had limited access to television and radio maintaining their own “flavor of speech”. My point being, if towns, cities, countries, planets, and Star Fleets are communicating with one another (or at least picking up each other’s broadcasts) then they’d adopt each others’ accents until their was barely any variation. Unless Scotland has become a major dominating force in the federation, then you’d better explain your token Scottish character. I’m counting this as “Silly Science” because the tendency for people in contact with one another to “mirror” each other has been proven and documented in psychology., Mush

, If ever someone contracts a fatal disease, that person is dead in less than 5 days. Whereas fatal debases such as AIDS, Diabetes, and Cancer, take roughly 3 to 10 years to kill you off. , Mush

, Aliens, who are living in hiding on Earth, never become science fiction writers. If you’re a benevolent alien trapped on Earth, and you know that humans are destined for space travel and an eventual “first contact”, then why don’t you prepare us humans with a novel that describes the various alien cultures and how to properly approach them? It’s easy enough to slap an adventuring hero on top of a “Visitor’s guide to Klingon society” and have yourself a decent Sci-fi., Mush

, Antibiotics of the future don’t give people upset stomachs., Mush

, If a “Universal Translator” fails, it turns off. It never spouts gibberish when it malfunctions. Imagine asking someone how their day went and them saying: “Ceratosaur. Breakfast is to the left of speckled-ness, and does if and only if magnet. The color white blends.”, Mush

, Aliens exploding and leaving no trace of a body when they are shot with a hand gun. (online flash games), Mush

, A mechanical planet (literally- a planet made up of plates of metal, gears, and pistons) populated by sentient robots, where there is no sign of an original biological race that built it all. It would be okay if “Funded by the men and women of foundation” logos were stamped every where, but robots can not be an initial life form on the planet nor can planets have natural forming gears or circuit boards. *cough* Transformers, Optimums Prime *cough* , Mush

, 2 dimensional star charts., Mush

, People who have air-tight hover-cars that can travel at thousands of miles per hour need rocket ships to safely travel from a planet to space. (Why not fly your car out to space?) , Mush

, While flying thousands of miles per hour in deep space, you can lean your head out an open window and feel the wind. (and scream: “Yeah-hoo! This is great!”) , Mush

, The kind of animals that can survive in the vacuum of space (in fact, it’s their habitat) are sharks, squids, stingrays, gigantic monkeys, genies, living dust clouds, Chinese dragons ,what ever species Yoda from Starwars happens to be, and what ever species Freeza from DragonBall Z happens to be. (I’m not talking about creatures that need spaceships to survive going though space.) , Mush

, Continuation of previous cliché Little is known about creatures that make deep space their habitat: like how they propel themselves, how they can smell blood from over 10 miles away, how they are able to make audible grunts and growls while still in a perfect vacuum, or how they are able to stay afloat even on the inside of a spaceship with artificial gravity. , Mush

, Robots and Talking computers whose 'voices' are seemingly recorded on analogue tape. At the first sign of malfunction the tape then plays at the wrong speed. Computer: Prepare to meet your doom! Hero: If all your words are pre-recorded, how can you give an appropriate answer to an unexpected future event? Computer: Maaaalfuuuunctionnnnn,,,,,,,,Eeeeeeemerrrrrrrrrgeeeencyyyyy......., GH

, The two-way communicator connects with the person in real-time, before the name has been said. E.G. Commander Riker taps his communication badge- "Riker to Picard," only Picard's badge sounds off and there is no connection delay for the communicator to resolve that Riker wants to speak to Picard and has to repeat the message. Same principle for "universal translators"- the communication is in real time without a delay for translating the words, let alone grammar and conjugation. Furthermore, the alien still mouths in English., RAC

, this is a rarely used cliche but used by jesus and its punching babies, JF

, lasers are often used instead of projectiles, it takes a lot of energy to make a laser that can blast through alien armor why not just make a piece of metal go really really fast and kill it. we have bullets why not just make them better (killzone does really well with this) also sometimes the aliens or humans use plasma weapons(Halo), firey blobs of death race towards you . why do lasers have a kick back, unless that light is really dense i can't see lasers having a kick back. for that matter why do projectile weapons have kickback (unless it uses magnets instead of an explosive)., MJH

, Universal Translators are amazing. Not only do they translate any language into English, but they also cause the alien's mouth to move in English too., SD

, What Was Spock Riding, Again? OR Boba Fett's Corollary. The more ridiculous a ship looks, the more maneuverable and effective it is in battle., SD

, They're Only Models! No matter how many moons that M-Class planet has, its gravity and tidal patterns will be exactly the same as Earth's. And if on the off-chance it isn't, one well-placed missile or torpedo to a random moon is all it takes to fix everything., SD

, No matter how big the planet is,the gravity is always the same as Earth's gravity., SBL

, clone gets memories of the person there cloned after then start to think they are them, jt
