Causal Set Theory and Cosmology

Abstract: Causal sets are fundamentally discrete structures proposed to underlie spacetime. A causal set is made of ‘atoms’ of spacetime related according to the causal relations between them. Causal structure, discreteness, covariance, and nonlocality play a prominent role in the physics described by causal sets, including cosmology. Causal set theory has touched on a number of fundamental cosmological questions. These range from the cosmological constant problem to the origin of cosmological horizon entropy. In this talk I will review some of these studies and highlight how the unique features of causal sets come into play.
