What are you waiting for?
I'll bet you $25 to your $1 that you don't supply a proof, payable via PayPal. Are we on? Only condition is you have to answer every question - no obfuscation, please.
It'd be well worth $25 if you have a proof of ZF consistency and I was one of the first to be able to give it. Has it been proven before? It seems people say "if ZF were consistent". Who has tried? Does Gödel's 2nd Theorem mean you'll do math that ZF can't?
