What is something in science fiction movies that is not accurate?

[MikeRJ]

For example, movie series like "Star Trek" and "Star Wars" always depict spaceships making noise going through space. While dramatic, sound can't travel in space since there is no air to carry soundwaves.

Basically nothing in Star Wars is remotely accurate - from the physics of the ships to the biology of aliens and creatures from the same planets, or military tactics. That's why it's generally referred to as Science Fantasy rather than Science Fiction. Another thing that Star Wars and the vast majority of space movies and games get wrong is turning entire planets into singular biomes with little to no diversity. This is fine for a barren rock with no atmosphere, but a terrestrial planet should have a full range of climates and terrain just like Earth.

The best effort at being somewhat realistic in space sci-fi that I've seen in a show was The Expanse, excluding a few egregious scenes in later seasons. They still had sound in space, but it was usually muted as if you were hearing the vibrations from inside the ships even though the camera was supposed to be outside. They also addressed problems in low-G environments that other shows never seem to consider, such as a lack of gravity making many medical procedures impossible.

Spacecraft maneuvering like aircraft.

Space battles seem very 2 dimensional as if they were ships on an ocean.

You can see the beginning and end of a laser beam as if the speed of light were only 45mph (72km/h).

Spacecraft slowing down and stopping when they run out of fuel, or just as bad, going vast distances and never needing to refuel.

They never have to wait for the turbo lift (at least not on Star Trek original series).

And finally, it's amazing how in the heat of battle, Spock can pull out a damaged circuit board, fiddle with it, put it back in working order without tools or spare parts.

Absolutely! One common inaccuracy in science fiction movies is the depiction of sound in space. As you mentioned, in a vacuum, like space, there is no medium for sound waves to travel through, so spaceships would be silent. Another example is the portrayal of rapid decompression. In reality, it would be much more catastrophic and less visually dramatic. Sci-fi often prioritizes drama over scientific accuracy 🌌🎬.

I think most of science fiction isn't too accurate.. Lucy with the 10% brain thing which the entire movie was based on.. LOL..

Dune while good movies are said not to be very scientifically accurate.. Like the sandworms for instance.. Or Spice being a substance used for too many purposes..
