Could the Barrow Universe be an antidote for cosmological singularites?

The article is dedicated to the Many Interacting Worlds (MIW) quantization approach, initially proposed by M. Hall, D.-A. Deckert and H. Wiseman in [1], as it is applied to the old problem of emergent cosmological singularities. We begin by discussing the history of de Broglie–Bohm theory and its evolution into the MIW formalism, followed by the direct application of MIW approach to Friedman cosmology in the model of Many Interacting Universes (MIU). After that we recall John D. Barrow's idea about the physical nature of zero solutions a(t)=˙a=0 for the Friedman equations and surmise the necessity for including such solutions into the framework of MIU. This works like a charm, as it directly leads to the Theorem 1 which, under some physically sensible assumptions, prohibits the remaining Friedman cosmological solutions from reaching zeroes, thereby preventing the formation of cosmological singularities. In conclusion we discuss some exact solutions to illustrate the aforementioned Theorem.
