We consider the holography and the fate of AdS vacua of various effective potentials. The dynamics of Coleman De Lucia type bubbles is described in some detail within the thin wall approximation. The holographic CFT is derived in terms of the parameters of the bulk configurations using a brane picture. A precise holographic dual of the decay process is proposed in terms of Fubini bounces in the unstable CFT. This proposal is backed by several qualitative and quantitative checks including the precise calculation of the action appearing in evaluating the decay rate. We also describe aspects of the long time behavior of the system, in particular those resulting in big crunches. We propose a qualitative scenario in which the crunch is resolved by stabilizing the CFT. In the stabilized model attempts at crunching are always shielded from the boundary by the formation of black hole horizons. In these well defined bulk processes all the configurations have the same asymptotics and are finite energy excitations of the ground state. This talk is based on work done with Jose Barbon.
