Kurt Gödel's 1931 proof showed that any formal system, including Principia Mathematica, is either incomplete or inconsistent, meaning it cannot prove all true statements or prove a false statement. This discovery, known as Gödel's Incompleteness Theorem, limits the ability of formal systems to capture all mathematical truths and has far-reaching implications for mathematics, logic, and ...
