10 Science Facts That Will Ruin Your Favourite Sci-Fi Movies

John Hammond's T-Rex "facts" are just plain lies...

There's nothing quite like the sinking feeling which viewers get when a piece of beloved sci-fi fumbles a technical detail and ends up embarrassingly misrepresenting scientific reality.

What's that? It's got fiction right there in the name, and just because it concerns science doesn't mean it needs to shoot for unerring accuracy all the time?

Maybe so, but even the most intentionally silly sci-fi flicks need to build tension and get viewers invested in their characters, meaning they need at least a modicum of believability for the story to have any stakes.

After all, viewers may not now how the xenomorph developed acidic blood, but given how far away and inhospitable their home planet is, it's conceivable that even their body make up would be lethal to humans. Similarly, a recent WhatCulture list of wasted twists noted that if M Night Shyamalan's The Happening had offered an in-depth explanation for its killer plants, it may be fondly remembered as more than a laughing stock nowadays.

With that in mind, this list is here to uncover the most egregious scientific missteps, miscalculations, and outright fabrications which have the power to turn compelling sci-fi classics into unintentional comedies.
