It’s astounding how little we know about the world. We could never know everything, of course, so to make it through life we apply principles and concepts to fill the gaps in areas we have no knowledge of. But things get really wonky when those concepts — our very understanding of how the universe operates — fail to explain something. Then, it seems like everything we know is a lie. These little factual tidbits (curated from this Reddit thread) might break your brain, but they’re all true (no matter how unlikely it seems).
