I think he's talking about the mathematical 'universe,' not the universe we live in. Apparently it's not so obvious what's absurd in the mathematical universe.

I think he's talking about the mathematical 'universe,' not the universe we live in. Apparently it's not so obvious what's absurd in the mathematical universe. Alternatively, maybe you and I can define 'absurd' very solidly, then go and overturn large portions of current mathematics. But I'm guessing that's more difficult than it sounds.
