Title: Holography in de Sitter space

Abstract:

In a strict sense, it could be said that the problem of quantum gravity has been solved by string theory through the AdS/CFT correspondence in settings restricted to the spatial infinity of a universe with negative cosmological constant. Currently, there are some outstanding questions of quantum gravity restricted to finite regions, as in the case of a positive cosmological constant where an observer only has access to partial information, as is the case for our observed universe. 
In this talk, I will review why quantum gravity is a problem through some of the basic conflicts between quantum mechanics and general relativity, and describe some of the proposed resolutions.
