Cosmic Acceleration: Past, Present, Puzzles and Precision
Presented by Raman Sundrum
University of Maryland

Monday, April 6, 2015
12:00 noon in 169-336

Abstract
I will review why cosmic inflation in the early universe as well as dark energy in the present era are so puzzling from the perspective of quantum field theory. I will then present some new ideas, involving unusual ingredients such as higher-dimensional dynamics or very small Equivalence Principle violations, that may address these puzzles. Finally I will outline how precision cosmological measurements can be used to test these ideas.
