When Worlds Collide
The greatest challenge facing string theory is the search for testable predictions. Surprisingly, one of the
most promising opportunities arises from observations of the largest structures in the universe. I will
present a broad overview of the aspects of string theory relevant to cosmology, specifically the string
theory "landscape" and the solution it provides for the cosmological constant problem, and describe some
recent progress in the search for observable signatures of string theory in the cosmic microwave
background and large-scale structure surveys.
