Things you learned from a scifi movie or TV show (good and bad ones)

[WyreWizard]

1.  Clones always come out looking like a mirror image of their genetic donors.  Same age and all.

2.  Tyrannosaurus Rex eat cows and sheep even though they aren't their indigenous diet.

3.  Cars of the future will not have wheels and will float a foot off the ground even though the Earth's magnetic field is weakening because of a reversal.

4.  Space ships can reach and surpass light speed without being torn apart by the extreme inertia.

5.  Poison can kill anyone instantly.  I mean forget the fact they have the travel through the body's digestive system or be slowly absorbed through the skin.

6.  Non-intelligent alien creatures are asexual and lay eggs to reproduce.

7.  Whale-like aliens can build a massive probe which can shut down the power of any system around them even though they don't have hands.

8.  When someone stops time with a magic pocket-watch, they always do the right thing.  They are immune to temptation.

9.  Sol (Our Sun) is a variable star that can become a blue giant, or red giant or even become a super nova.

10.  When a star, planet or other massive super body is destroyed, they let out a visible shock wave that looks like a flat ring even though space is three-dimensional.

11.  Millions of years ago, aliens came to our world and planted the seeds of intelligence in early human ancestors.

12.  When an alien creature is black, its circulatory fluid is very corrosive and they reproduce in the same manner as the Ichneumon Wasp.

13.  Sometimes, music from an old record is all you need to repel an alien invasion.

14.  When a human is 5 inches tall, normal sized humans can hear their voices.

15.  When a Human is 70 feet tall, they have few if any health problems.

16.  Hundreds of thousands of years ago, Neanderthal humans existed in complex societies even though they couldn't count above 5.  They talked with a combination of spoken words and hand signals.  And neanderthal humans didn't look much different from us.

17.  Doctors in the far future care much about human comfort and happiness as modern doctors;  they don't give a damn.  Just keeping the patient alive is all that matters.

18.  A town named after an exclamation word said by chemists and inventors is a place of high technology and discovery.

19.  Technology exists that can accurately read the complex chemical chains of human thought and memory.

20.  Big business is able to get away with breaking the law.  (I didn't get this from a movie or TV show, but from real life.)

21.  Medicine created by aliens on a distant planet is able to cure most human ailments.

22.  Alien borne pathogens and parasites are able to use Humans as hosts.

23.  Many millions of years from now, humans will evolve into creatures with very large heads and very lithe bodies.

24.  All aliens are very human-like.

25.  Aliens which are multi-pedal have a tendency to hide from humans.

26.  Stealth technology which can bend light around it is feasible.

27.  On other planets, there are giant and insect-like creatures.

28.  Some of these creature can even store millions of terawatts in their bodies without being incinerated.

29.  These creatures are led by giant, brain-like bugs with ten eyes that feed on human brains.

30.  When making a sci-fi movie based on a sci-fi novel, try to make it have as little as common with the original story and the only solid commonality is the title.

Aliens know nothing of romantic love until humans arrive, but they are VERY eager to learn.

Guns work underwater.

No matter where you shoot someone -- in the toe, in the arm, in the keester -- you know they're hit because blood pours out their mouths.

All aliens are bilaterally-symmetrical, one-headed, two-eyed, two-legged, two-armed affairs.  And they all speak English.

All alien life is much more advanced than we are.  The more advanced they are, then more likely they are to wear togas and to claim to have transcended all emotion.

From the Star trek Universe: Most aliens look just like humans but with funny-looking foreheads and/or ears.

[Fishasaurus]

Most bad-news aliens eat one hard-to-get item to the exclusion of all else, like the evil race that eats only the brain stems of Metamorphs on Space 1999, or the salt-eating alien that disguised itself as Dr. McCoy's girlfriend on Star Trek that one time.  They do not require balanced diets, and if there is only one Metamorph brainstem left in the galazy, a whole spaceship filled with hale and hearty evil aliens will converge on that last Metamorph -- looking not at all as if they were starving to death.  They also never fight among themselves for that last brain stem, or decide to do something sensible like make the Metamorphs breed more to provide a more stable source of food, or grow their brain stems in test-tubes so everyone can have one.
