Multiverse in Karch-Randall Braneworld

In this paper, we propose a model based on wedge holography that can describe the multiverse. holography, consider two gravitating baths, one of which has strong gravity and other weak gravity. To multiverse, $2n$ Karch-Randall branes, various $d$-dimensional universes are localized these branes. These branes embedded in $(d+1)$-dimensional spacetime. The is useful obtaining Page curve black holes with multiple horizons resolution ``grandfather paradox''. We explicitly obtain curves eternal AdS for $n=2$ multiverse Schwarzschild de-Sitter hole horizons.
