Title:     When Worlds Collide

Abstract: I will discuss some cosmological implications of the string theory landscape, focusing on Coleman-de Luccia bubbles and scenarios
in which two such bubbles collide. I will analyze the dynamics of these collisions in the thin wall limit and discuss potentially observable signals in the CMB such as hemispherical power asymmetries, cold and hot spots and non-gaussanities.
