Sci-Fi or Bad Try?

If you are interested in science and like Sci-Fi movies, have you ever noticed discrepancies in the way a movie is shown in a theater and reality? I know - it happens all the time, but do you mind gross inadequacies as far as the story framework/picturization is concerned?

Popular Science has an interesting compendium of movie mistakes where a science fact is depicted incorrectly. Visit this link to see the list for yourself. Interesting stuff, with calculations and all.

Moviemakers, remember this:

Sound does NOT travel through the vacuum of space

Conservation of momentum still holds true

Archimedes died, not his theorem

Same with Newton - the three laws haven't been disproved yet

We haven't been in outer space and neither have you. If you want to take us for a ride, keep it close to the facts (gravity and the whatnots)

And thanks for the incredible visuals. The movie experience has never been better.
