Abstract
In this work it is proposed an alternative scheme for an Emergent Universe scenario in the context of a Jordan-Brans-Dicke theory, where the universe is initially in a static state supported by a scalar field located in a false vacuum. The universe begins to evolve when, by quantum tunneling, the scalar field decays into a state of true vacuum.In particular, in this work we study the stability of the static universe, under the aforementioned characteristics, and the probability of creating a true vacuum bubble. It is shown that in this model, unlike what happens in previous works, the static universe is stable under small classical perturbations.
