Gödel's Proof · 1958
In any sufficiently powerful formal system there are true statements that cannot be proved using its own rules.
Gödel somehow built a mathematical statement that says about itself I cannot be proven here. If the statement were false, the system would prove something wrong, which cannot happen. If it is true, then there exists a truth the system cannot reach on its own. Math has real limits.
