Which theorem states that for a powerful enough system to explain the arithmetic of natural numbers, some propositions can be neither proved nor disproved?

  • First incompleteness theorem

  • Second incompleteness theorem

  • Completeness theorem

  • Continuum hypothesis

Answer

Gödel's first incompleteness theorem states that no consistent system of axioms whose theorems can be listed by an "effective procedure" (essentially, a computer program) is capable of proving all truths about the natural numbers. For any such system, there will always be statements about the natural numbers that are true, but that are unprovable within the system. This result has profound implications for the foundations of mathematics.
