Gödel's incompleteness theorems

Gödel's Incompleteness Theorems are ideas from mathematics that say that no set of rules (like a math equation or game) can answer every single question about itself. This means that if you use a set of rules, no matter how detailed, you will never be able to answer every single question about it. This is because some of the questions will be too hard to figure out and will never get an answer.
