Axiom Memes

The infinite recursion nightmare that keeps mathematicians up at night! In set theory, the Axiom of Foundation prevents sets from containing themselves (no set can be an element of itself). But this cat is staring into the mathematical abyss of nested sets that keep looking inside other sets... forever. It's like mathematical inception where each level gets more terrifying. The cat's expression perfectly captures the existential horror of realizing you've violated the very foundations of mathematics. Guess the cat didn't get the memo that self-referential sets cause paradoxes that could collapse the entire mathematical universe. Russell's paradox has never looked so fluffy!
