Abstract

In the last few years there has been a burst of progress in the field of massive gravity.  The construction of consistent theories in which the graviton has a small mass has in turn led to the development a new family of compelling, consistent low-energy modifications of General Relativity.  These theories improve our understanding of the interplay between gravity and particle physics and provide new approaches to solving the cosmological constant problem.  In this talk I will review these recent developments.  I will discuss the search among these new theories for a symmetry that has the potential to address the cosmological constant problem.
