### Description

According to quantum field theory, the vacuum is a space all kinds of
energetic particles and oscillating fields, which is in a state of
statistical equilibrium is characterized by physical parameters and
structure. Since the quantum vacuum pervades the entire extent of the
universe then the study of its properties is a topical problem for deeply
understanding of cosmology and in general for foundations of modern
physics. Assuming that the quantum theory of field is possible precisely
to describe without perturbation methods then the properties of the vacuum
obviously will be analogous to the properties of an ensemble of the
quantum harmonic oscillators. For the first time we considered this
problem within limits of the stochastic differential equations of
Maxwell--Langevin type. In particular assuming that fluctuations of the
fields satisfy to properties of the ``white
noise" , we proved that the
Casimir vacuum in an equilibrium is described by the $10$-dimensional
space-time, where $4D$ is the Minkowski space-time, while $6D$ is the compact
topological space with the linear sizes of order $10^{-20}$ cm. It is shown
that in the compact subspace is localized the main part of vacuum energy,
which can claim the role of dark energy.
