My memory is that it was thought to be unprovable but later proven to not be
so. However, wikipedia (Cardinal_numbers) agrees with you. Not that it's
unprovable, but that its provability depends on the axioms of set theory you
accept. I suspect it depends in part on things like the axiom of choice, etc.
