The real world bridge is a model.* If the real world bridge is a model then give me a example of something that is not a model, if you can not then the word "model" has no meaning. Unlike the Continuum Hypothesis the Goldbach Conjecture is subject to the potential of experimental falsification, if logicians eventually proved that it is true, that is to say they started with nothing but their axioms and derived it, but then the next day a computer found a huge even number that was NOT the sum of two prime numbers I think logicians would be very upset, or at least the competent ones would be. I think they would say that shows their present axioms must not be "sound" in the technical sense and need to be modified. I don't think they would say "the laws of physics that the computer runs on must be wrong and our model is right and every even number is the sum of two primes and thats that and I don't want to hear anymore about it"; but if I'm wrong and they did say that then I would no longer be interested in anything logicians said in the future because they would be jackasses. But I don’t think they’re jackasses because good logicians know there is a difference between proof and truth, physics will always tell you the truth but a proof is only as good as the axioms it is based on. > > > > *Your models would be called theories, and the real world bridge either > satisfies it or not.* You say the real world bridge is a theory, so now we have theories about theories? Give me an example of something that is not a theory, if you can not then like "model" the word "theory" has no meaning either.
