TAP Colloquium- Is the standard cosmological model in crisis?
Dr. Marco Raveri, University of Pennsylvania
Abstract: The standard cosmological model is today challenged on the theoretical side and by several pieces of experimental evidence. On one hand, the model seems incompatible with the low energy limit of string theory, on the other hand, different observations of early and late times show different pictures of how the universe evolved. After discussing how severe these challenges are I will present different attempts at resolving them by invoking new physical ingredients in the early or late universe. I will then discuss the role of future cosmological probes in resolving the current crisis.
