Abstract
We consider the fate of AdS vacua connected by tunneling events A precise holographic dual of thinwalled Colemande Luccia bounces is proposed in terms of Fubini instantons in an unstable CFT This proposal is backed by several qualitative and quantitative checks including the precise calculation of the instanton action appearing in evaluating the decay rate Big crunches manifest themselves as time dependent processes which reach the boundary of field space in a finite time The infinite energy difference involved is identified on the boundary and highlights the illdefined nature of the bulk setup We propose a qualitative scenario in which the crunch is resolved by stabilizing the CFT so that all attempts at crunching always end up shielded from the boundary by the formation of black hole horizons In all these well defined bulk processes the configurations have the same asymptotics and are finite energy excitations
