Abstract
We study the motion of thinshell bubbles and their tunneling in anti de Sitter AdS background We are interested in the case when the outside of a shell is a SchwarzschildAdS space false vacuum and the inside of it is an AdS space with a lower vacuum energy true vacuum If a collapsing true vacuum bubble is created classically it will form a SchwarzschildAdS black hole However this collapsing bubble can tunnel to a bouncing bubble that moves out to spatial infinity Then although the classical causal structure of a collapsing true vacuum bubble has the singularity and the event horizon quantum mechanically the wavefunction has support for a history without any singularity nor event horizon which is mediated by the nonperturbative quantum tunneling effect This may be regarded an explicit example that shows the unitarity of an asymptotic observer in AdS while a classical observer who only follows the most probable history effectively lose information due to the formation of an event horizonThis article is published under an open access license Please check the Copyright Information section for details of this license and what reuse is permitted If your intended use exceeds what is permitted by the license or if you are unable to locate the licence and reuse information please contact the Rights and Permissions team
