Bad Science in Movies

Fun to read, but not really accurate in my opinion ;)

Apollo 13 was great, and almost perfect, but there was one thing that bugged me every time I saw it. The gauge showing CO2 percentage should have been moving very slowly, but every time they showed it the hand was sweeping dramatically towards the danger point. It would have been fatal in seconds if it continued moving at that speed, and each time they showed it it started from the same lower point and swept up. Should have been still in the shots, each time at a slightly higher level.

yeah man, i agree, it's clearly a film technique used to represent something metaphorically

the people who made this chart know very little of film, science fiction, or science

I'm hoping they aren't classing the "long pull out" at the start of Contact as "sound in space" because it isnt. Its supposed to represent our signal sphere of broadcasts as you recede from Earth.

You get present day broadcasts at Earth trailing off to vintage and grainy broadcasts as you get into the stars. I think our signal sphere is about 85 light years in radius at them moment?

In no way was it meant to be sound in space if thats what they were thinking.

Star wars (I'll even include the prequels, though I do not have to):

All planets have Earth gravity. No, they all had earth-like gravity. Endor's was a little lower, Hoth's a little higher.
All planets have a climate planet-wide. Alderaan, Endor, Yavin, and Naboo had multiple climates. Bespin and Hoth might well have had a gradient of gas giant and snow world climates respectively. Coruscant would have before it became an unending city with climate control.
Easy communication with aliens. Protocol droids and 25,000 years of interspecies interaction.
Nearby asteroids aren't drawn close by gravity. We saw asteroids for minutes and they were moving at unrealistically high speeds and close to each other. This one is not really able to be ruled on without at least a few hours of star wars asteroid footage.
Faster-than-light travel. Hyperspace is like sub-space, you don't move faster than light, you shift into a plane where the relative distances are warped shorter and traverse them at sub-light speeds. That's why you use the sublight engines in hyperspace.

Enemy Mine:

All planets have Earth gravity. Two planets are shown with two earth-like gravities.
All planets have a climate planet-wide. Two planets with variable climates and seasons.
Easy communication with aliens. Two aliens in the entire galaxy that have had a prolonged war, probably have special teams dedicated to translating war messages and codes, and it takes a long time for them to learn each others' language.
