Is It Dark Matter, or Is Spacetime Undergoing a Random Walk?
summary
Presents a concrete, completely positive trace‑preserving master equation that couples classical phase‑space variables to quantum density matrices, producing a dynamics that is Lindbladian plus Fokker‑Planck with a required decoherence–diffusion trade‑off. Demands stochasticity in the classical sector, yields Brownian‑type backreaction and a path‑integral whose Euler‑Lagrange solutions add low‑acceleration and cosmological‑constant‑like terms; these produce MOND-like acceleration for galactic rotation curves, predict experimental bounds from heavy‑object coherence times, and raise locality/ heating tensions.
