[MV] Multiverse
- Salvador Robles
We present the nucleation of a false vacuum bubble in curved space, which have compact geometries. The analytic computations for the radius and nucleation rate of a vacuum bubble are evaluated using the thin-wall approximation. We discuss possible cosmological implications of our new solutions.
We will present a recent result [1] regarding the cosmological constant problem. In the framework of the piecewise-linear approaches to the construction of the gravitational path integral, there are three contributions to the total cosmological constant (CC): the bare term, the matter vacuum fluctuations term, and the quantum gravity term. The existence of the quantum gravity term is necessary...
The paradigm of an interacting multiverse opens the door to a new wide variety of cosmic phenomena to be explored. In this talk, we shall show that the interactions among the universes of the multiverse may change the global properties of the universes without violating their notion of causal closure (in the local sense). These changes would eventually have observational consequences on the...
