    "abstract": "Nondifferentiable fluctuations in space-time on a Planck scale introduce\nstochastic terms into the equations for quantum states, resulting in a proposed\nnew foundation for an existing alternative quantum theory, primary state\ndiffusion (PSD). Planck-scale stochastic space-time structure results in\nquantum fluctuations, whilst larger-scale curvature is responsible for\ngravitational forces. The gravitational field and the quantum fluctuation field\nare the same, differing only in scale. The quantum mechanics of small systems,\nclassical mechanics of large systems and the physics of quantum experiments are\nall derived dynamically, without any prior division into classical and quantum\ndomains, and without any measurement hypothesis. Unlike the earlier derivation\nof PSD, the new derivation, based on a stochastic space-time differential\ngeometry, has essentially no free parameters. However many features of this\nstructure remain to be determined. The theory is falsifiable in the laboratory,\nand critical matter interferometry experiments to distinguish it from ordinary\nquantum mechanics may be feasible within the next decade.",
