Description: >This talk frames matter and energy as emergent from local zero-point energy (ZPE) field density and asks what becomes possible if ZPE density can be engineered. > It critiques the way early quantum theory “ghosted” the vacuum, then highlights stochastic electrodynamics (SED) as a physical-plenum alternative: a Lorentz-invariant sea of real fluctuations where inertia can be modeled as ZPF Lorentz drag (HRP), with extensions that treat constants as density-linked and time-variable (e.g., Setterfield). > From there it introduces the “Miller Framework” as an engineering roadmap for “vacuum metric engineering,” built around six pillars (Madelung-style vacuum-as-fluid transition, a refractive-index-like coupling constant, Bohmian-trajectory thrust concepts, a nonlinear thrust scaling law, a “quantum packing fraction” coherence threshold around 4.64, and a recursive saturation threshold positioned as a lower-energy path compared to the Schwinger limit), aiming at propellantless thrust and vacuum-catalyzed fusion concepts.
