"ETH is false": CS community buzzing over claim that upends SAT exponential-time assumption
akbirthko · x · 2026-10-27
Engineer Eric Zhang (ekzhang1) tweeted that he was planning a quiet evening until he saw news that "ETH is false" — referring to the Exponential Time Hypothesis in theoretical computer science.
He reflects that some things you learn in your first CS class — like SAT requiring exponential time — you simply stop questioning, assuming smarter people have scrutinized them forever. If the claim holds, it would undermine many complexity lower bounds built on ETH. Details of the alleged result are not yet confirmed in this thread.
