Recent Progress in Gravity Tests of Spacetime Symmetries

We provide a brief overview into recent tests of gravity, focusing on its foundational spacetime symmetries. In particular, we work with an agnostic, effective field-theory framework, named the Standard-Model Extension, that allows for analysis of tests of such symmetries. There have been a wide range of experiments and theory developments that have helped contribute toward constraining terms within the framework, providing clues to a possible underlying, unified theory of physics.
