11 Sci-Fi Movies That Got Science Completely Wrong

2013's Gravity was hyped as an ultra-realistic astronautical thriller, although it only really delivered on 2 out of those 3 promises.

Gravity's realism - and much of its credibility - went out of the window long before the movie's climax. Ryan Stone (Sandra Bullock) and Matt Kowalski (George Clooney) are in the middle of a routine spacewalk when disaster strikes, causing their shuttle to be irreparably damaged. While attempting to reach the safety of a Soyuz capsule, Stone becomes tangled, and Kowalski begins floating off into space.

Believing that his momentum will doom the pair, Kowalski bravely decouples their tether and floats away, saving Stone's life.

Or, that's what we're supposed to believe.

In reality, all it would have taken to save Kowalski would be a gentle tug from Stone, who was attached to a solid object. The scene is an insult to basic physics, and asking audiences to believe it as the movie's emotional core is even more insulting.

Put simply: how did the two end up in space if they don't understand how physics will work once they're out there?
