i just learned that there's a combination of about twenty Magic: the Gathering cards you can play where the amount of damage you deal is either a finite massive number or infinite depending on whether the twin prime conjecture is true
reading through the explanation over the course of like 45 minutes (yes, it's that complicated) had me cry-laughing in disbelief at multiple points
i have never been more proud of my community
for those interested, the deck is described here: https://www.reddit.com/r/BadMtgCombos/comments/1feps3y/deal_infinite_damage_for_4gru_as_long_as_the_twin/
