Título: Higher order stochastic equation for the quantum gravity of the primordial time


Resumo: Here we suggest that quantum gravity might obey the laws of a stochastic quantization that is governed by a higher order Langevin equation rather than by a first order stochastic equation (or, equivalently, a higher order Fokker-Planck equation).

With this consistent modification of the quantisation, fast vacuum fluctuations may occur when the stochastic time evolves and modify the smooth stochastic time relaxation phenomena that governs quantum physics when the equation is first order. Vacuum fluctuations are accompanied by an abundance of quantum creations and annihilations of the relevant quantised states of the systems.
