Description |
Resolution of cosmological singularities is an important problem in any full theory of quantum gravity. Three dimensional de Sitter space has quotients that have big-bang/big-crunch singularities, while the Milne orbifold is a quotient of flat space (cosmology) with a big-bang/big-crunch singularity. Using the Chern-Simons formulation of higher spin gravity in 2+1 d de Sitter and flat space we show that higher spin theories can effect a simple resolution of the cosmological singularities when one embeds them in 2+1 dimensions. |
