... arithmetic systems considered by Gödel [13]. If you construct a mathematical theory “in the air”, disconnected from observations of reality, then you can’t know if Gödel’s theorem applies because it only applies to certain types of theories that are known to be consistent, but if a theory is incomp ...

The Klein-Gordon equation has a solution with exactly twice the free parameters of the Schrödinger Equation solution But 80 years of experiments say we can’t learn any more information (at one time) than can be encoded by .
