Plato Meets de Sitter, or de Sitter's Allegory of the Cave (2405.08080v2)
Published 13 May 2024 in hep-th and gr-qc
Abstract: Configurations of masses located at the vertices of Platonic solids deep within the bulk of de Sitter spacetime generate deformations of the cosmological horizon with the geometry dual to these polyhedra. The horizon data encodes both the symmetries and sizes of the solids in the bulk.
