This Workshop is the twelfth conducted by the Simons Center for Geometry and Physics at Stony Brook and the seventeenth in the series Simons Summer Workshops. This year’s summer workshop will focus on cosmology and its realization in string theory.  We review the status of observational data, both in the context of the very early universe as well as more recent epochs, with particular focus on the observational data on dark energy and dark matter.  Moreover we discuss various theoretical ideas in cosmology, such as inflationary models and the associated challenges in their realization in string theory as well as novel stringy inspired approaches to solving cosmological issues.  The main aim of this workshop is to generate new ideas needed to bring string theory closer to cosmological observations as well as possibly leading to new stringy predictions for the dark sector.

Schedule Week 1 Schedule Week 2 Schedule Week 3 Schedule Week 4

Mondays, Tuesdays, Thursdays, and Fridays

All talks will be held in the Simons Center for Geometry and Physics Lecture Hall (Room 102).

Breakfast will be served daily from 9:00am-10:00am in the Simons Center Cafe, 2nd floor.
