The Truth Behind Set Mathematics: Is the Foundation of Math Being Rewritten?
By Sophia Al-Mansoor
The ultimate stress test for set mathematics emerged from Cantor's first great open question: the continuum hypothesis. Cantor wanted to know if there is an infinite set with a cardinality strictly between the natural numbers and the real numbers. He guessed no. For decades, researchers tried to prove it.
In 1940, Gödel proved that you cannot disprove the continuum hypothesis using the standard ZFC axioms. In 1963, Paul Cohen developed a technique called forcing to prove that you cannot prove it either. The continuum hypothesis is completely independent of the foundational axioms of mathematics. Cohen won a Fields Medal for the work, but his result left a deep philosophical bruise.
If the bedrock axioms of set theory cannot determine the size of the real number line, are sets the right foundation for mathematics? Logicians divided into competing camps. Some, following W. Hugh Woodin, advocate searching for new, deeper axioms to settle the continuum problem once and for all. Others argue that mathematics is fundamentally pluralistic, meaning different mathematical universes exist depending on the axioms you select.
