“…Or is it? One of the people who invented the idea that the universe as a whole can (and probably should) be treated as a quantum object was Pedro F. González-Díaz [2]. One of the authors (AYu) had a chance to work together with Pedro, and can attest to Pedro's amazing capacity for generating very bold and novel ideas.…”

In this article we present a new outlook on the cosmology, based on the quantum model proposed by M. Hall,. 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 in [1]. The crux of the idea lies in the fact that unlike every other interpretation of the quantum mechanics, the Hall, Deckert and Wiseman 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".
