Rick,
As a fellow physicist you know that the line between Maths and Physics was drawn by Galileo - Physics only existed after he set the experimental standard of applying a mathematical theory to reality. It's not my definition of Physics, it's Galileo's. Every theory starts as *just* a mathematical theory until experimentally verified and shown not to contradict known experimental results. Reproducing known theories by different means - which both you and I have done - meets the Galilean standard of Physics as the known experimental results are entailed (question answered).
In the Standard Model, the spectrum of particles and their coupling constants are added by hand from experimental results. Dimensional compactification defines a whole class of mathematical theories that seek to derive the particle coupling constants from the GR constants and a compactification scale. The 11D GR theory referenced in my essay is one of this class of theory and succeeds by *deriving* the full spectrum of particles so that they do not have to be added by hand - this is not present in the Standard Model or any associated principles. The GR scenario is uniquely defined mathematically by the occurrence of the spheres S0, S1, S3, S7 as physical manifolds and this is directly linked to the successful reproduction of known physics without any additional features that conflict with known physics. This includes the derivation of the correct Standard Model Lagrangian and QFT. These characteristics *are* unique.
The acknowledgement of "if and only if" in Godel's mathematical incompleteness is PRECISELY my point. It is conditional on integers, which is the case in classical physics for particle numbers. The calculation of the rest mass of the particles derived in 11D GR as topological defects is subject to Godel's mathematical incompleteness because of this "if and only if" condition. A mathematician would be stumped at this point, but as physicists who know that maths is just a formal language for describing reality, we are free to drop the "if and only if" condition of strictly using integers to denote particle numbers and switch to real numbers instead - the wave-function - mathematical incompleteness then vanishes. If you trace the mathematical consequences of this shift in the theory, you find that it is of the form of quantum theory. Hence, QT is not fundamental because I can derive it!
This implies that mathematical incompleteness is not so much a red herring, but the elephant in the room.
