2. Gravity (2013) – Physics In Space
One of the most notorious plot holes of all time, Gravity‘s entire story is built around an inconsistency so large that real-life physicists have explained just how badly it ruins the movie. Gravity begins with Dr. Ryan Stone (Sandra Bullock) and Matt Kowalski (George Clooney) on a routine spacewalk when things begin to go awry. Despite taking proper safety precautions (such as tethering to one another), Stone finds himself drifting into space and makes a noble sacrifice, detaching the tether to allow Stone to survive as he drifts off into space.
Except, that’s not how physics work in space. As the pair are in a vacuum, all that needed to happen was for Stone to pull gently on the tether, and Kowalski would have begun floating back to safety. The solution really was that simple, which massively undermines what essentially formed the dramatic crux of the film.
Gravity‘s biggest crime is actually far more grievous than it seems. The space-set story should have a solid grasp on the basic physics and procedures of space walks, and the fact that it doesn’t makes this plot hole hard to bear. Watching Gravity with knowledge of just how stupid and pointless Kowalski’s death is actually ruins the film completely, because it makes it seem so incredibly unintelligent that it’s hard to care what happens to Stone afterwards.
