By Dongsu Bak and others

We consider a time-dependent *\mathcal{O}(1/G)* deformation of pure de Sitter (dS) space in dS gravity coupled to a massless scalar field. It is the dS counterpart of the AdS Janus deformation and interpolates two asymptotically dS spaces in the far past and the far future with a single deformation parameter.... Show more
