摘要
It is already understood that the increasing observational evidence for an open universe can be reconciled with inflation if our horizon is contained inside one single huge bubble nucleated during the inflationary phase transition. In this frame of ideas, we show here that probability of living in a bubble with the right Omega(0) (approximate to 0.2) can be comparable to unity, rather than infinitesimally small. For this purpose we modify both quantitatively and qualitatively an intuitive toy model of ours. Therefore, inferring from the observations that Omega(0) < 1 nor only does not conflict with the inflationary paradigm, but rather supports therein the occurrence of a primordial phase transition.
