| contents | Does a nontrivial gravitational excitation require a modified internal gauge theory constitutive law? As there is no canonical mapping between differential forms valued in distinct Lie algebras, the answer is negative, and entirely dependent on the specific unification scheme. A structural formulation in BF theory in terms of a constitutive diagram between the excitations of different interaction sectors is provided, alongside a discussion of the structure of the broken phase. As a nontrivial option, a "spontaneous" breaking into the physical constraint is attempted, however it is shown that basic B-potentials alone would not be viable. A heuristic discussion of internal gauge theory and gravity is provided, and by conflating the observer's internal and external state with the spacetime tangent structure, it is argued that there is a simple geometric obstruction to a nontrivially unified phase. A more ad hoc treatment of gauge theory and gravitational structure remains as the clear path forward, while observer, signal and causal considerations would suggest studying alternative backgrounds to the manifold topology. |
