As WIRED's own physics blogger Rhett Allain has pointed out, science fiction movies don't have to have perfect science. Who would argue such a thing? They're supposed to be fun! But ... well, some violations of basic physics and biology are worse than others. So our science team took at look at some of the year's best sci-fi with an eye toward correcting the errors. The narrative results, though? They weren't pretty.

The Martian

Spend two years on Mars in a flimsy hab, and your Christmas present would be cancer. Cancer in a sensitive place. The surface of Mars is bathed in a sterilizing amount of ionizing radiation.

Avengers: Age of Ultron

First, Iron Man would remember that he took the arc reactor out of his chest at the end of Iron Man 3, and the arc reactor was powering his armor, so he’d fall out of the sky to his death, crushed by his metal suit. Quicksilver would disappear in a puff of oxidation, consumed by the metabolic demands of his own body. The Hulk’s ability to acquire mass from nowhere would go out of control according to his rage, thereby creating an unstable naked singularity and destroying the Earth … but not before Facebook and Google would realize that Ultron was the artificial intelligence they’ve been looking for and plug him into their algorithms to deliver ads and likes. Let's see how megalomaniacal he is when the tech bubble bursts! Poor schmuck.

Jupiter Ascending

I mean … come on. Jupiter would leave her half-wolf, winged boyfriend when his pecs had to become so mega-gigantic to power his wings that he wasn’t pretty enough (and let’s face it, she was a little shallow). The localized distortions of physics necessary to make flying space roller skates work would spread out of control, bending and twisting spacetime into an unpredictable pretzel. Faced with ownership of the Earth, Jupiter would eventually stop cleaning other people’s bathrooms.

Tomorrowland

One of the child AIs sent to kidnap “dreamers” back to the pocket universe of Tomorrowland would set off a metal detector, leading to discovery by the TSA. Once the rest of the world found out that a certain class of person deemed acceptable by the rulers of Tomorrowland was being allowed to live in a libertarian, Randian utopia of deregulated science.

Mad Max: Fury Road

Actually, I’m pretty sure this one’s accurate.
