Sorry, getting used to the rules. The paper below discusses pilot carrier waves in terms of hydrodynamics.

I see your point about wanton speculation...
Open question: Can we be sure that a quantum model double slit doesn't create a carrier interference pattern around the slits, in the fields, already there? Relativity is such a big deal in physics but so many models only consider seemingly weird quantum particles going through normal classical...
