de Sitter (dS) space plays an important role in the study of cosmology: in the physics of inflation during the early universe and in the physics of late time cosmology. A proper understanding of the QFT is necessary, but is out of reach with the standard techniques of QFT on a curved spacetime. More powerful nonperturbative method is needed. In this talk I review some recent progress in the study of a holographic nonperturbative duality between conformal field theory (CFT) on de Sitter space and string theory on Anti de Sitter (AdS) space, and how such a duality may help us to tackle some of the challenging physics problems on de Sitter space.
