> All true claims are unfalsifiable by definition. That’s not what ‘falsifiable’ means. ‘Pi is irrational’ is falsifiable, in that if you can show me integer p and q such that p/q = pi, you would have demonstrated that statement to be false. The fact we can show that no such p and q exist is what renders the truth of that statement proven. ‘Falsifiability’ of a statement is the property that makes the statement amenable to being evaluated for truth.
