   A lot of this has confusing terminology and language. I could go into   
   some aspects of this with conformal gravity and how entanglement occurs   
   between black hole horizons and fields approaching I^+. The local   
   Lorentz group is restricted to i^0 and off of that on I^+ and I^- are   
   additional symmetries. However, that would be beyond this scope and   
   frankly the symbolic capacity of the limited abilities with this group   
   page.   
      
   With respect to the Weyl curvature we can write the gravi-electric field   
   tensor as E_{ac} = C_{abcd}g^{bd} and the Hodge dual is the   
   gravi-magnetic field. The C_{abcd}C^{abcd} is analogous to   
   1/2(E^2 - B^2) Lagrangian for EM. These fields are tensors because   
   they have two helicities. Further, the Weyl tensor is often worked in   
   complex variables as these are conformal. So q-variables are workable.   
      
   However, I think that gravitation and in particular quantum gravitation   
   is such a weak influence that it has negligible impact on this   
   problem. Even if one can measure aspect of gravitational curvature, and   
   there are atomic clocks sensitive enough to measure the gravitational   
   time dilation or curvature of small masses, that ignoring this is   
   possible. Quantum mechanics does not necessarily hold a counterfactual   
   definite proposition. So the unperformed measurement or experiment has   
   no empirical consequences.
