In arithmetic if ZFC or any set of axioms says that a number with certain mathematical traits can not exist but a computer finds a number with exactly those mathematical traits then both of them can't be correct, and in that situation I simply don't believe you'd take the part of the axioms because you are not insane. > > It really underscores Chaitin's point that at some level of > complexity, mathematics becomes an empirical subject, perhaps not all > that different from physics. > Yes mathematics can be empirical, and that means regardless of how beautiful your axioms are if the experimental evidence conflicts with them then those axioms then they have to be junked because experimental evidence outranks everything. The mathematical counterpart to a test tube is a computer and the fundamental operating system of any computer is the laws of physics. So physics can exercise veto power even in pure mathematics.
