Abstract:

Resolution of cosmological singularities is an important problem in any full theory of quantum gravity. Three dimensional de Sitter space admits quotients that have big-bang/big-crunch singularities and so does the Milne orbifold which is a quotient of 2+1 flat space. 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 execute a simple resolution of the cosmological singularities when one embeds them in 2+1 dimensions.
