Towards causal patch physics in dS/CFT

Understand

This is a status report on a research program aimed at obtaining quantum-gravitational physics inside a cosmological horizon through dS/CFT, i.e.

• through a holographic description at past/future infinity of de Sitter space.
• The program aims to bring together two main elements.
• The first is the observation by Anninos, Hartman and Strominger that Vasiliev's higher-spin gravity provides a working model for dS/CFT in 3+1 dimensions.
