  In this article we present a new outlook on the cosmology, based on the
quantum model proposed by M. Hall, D.-A. Deckert and H. Wiseman (HDW). In
continuation of the idea of that model we consider finitely many classical
homogeneous and isotropic universes whose evolutions are determined by the
standard Einstein-Friedman equations but that also interact with each other
quantum-mechanically via the mechanism proposed by HDW. The crux of the idea
lies in the fact that unlike every other interpretation of the quantum
mechanics, the HDW model requires no decoherence mechanism and thus allows the
quantum mechanical effects to manifest themselves not just on micro-scale, but
on a cosmological scale as well. We further demonstrate that the addition of
this new quantum-mechanical interaction lead to a number of interesting
cosmological predictions, and might even provide natural physical explanations
for the phenomena of ``dark matter'' and ``phantom fields''.
