Diósi–Penrose Gravitational Decoherence Times Across Mass Scales with a Density Ceiling
Year: 2026
Type: article
Abstract: This paper evaluates Diósi–Penrose gravitational decoherence times from the electron to macroscopic masses and asks whether a maximum density alters the picture. The computed time is 5.665e+19 seconds for a proton displaced by its own scale, 1.097e+15 seconds for a fullerene molecule, and 1.580e+00 seconds for a dust grain of 1e-15 kilograms. The density ceiling of 9.717e+57 kilograms per cubic metre lies far above the densities of all systems tabulated, so it leaves the standard gravitational decoherence estimates unchanged. The strong mass dependence, not the ceiling, is what separates microscopic superpositions, which persist, from macroscopic ones, which localise promptly in this model. The study is simulated and computed from stated assumptions; it is not a measurement.
