DESCRIPTION:We do not understand 95% of our Universe. 63% of this unknown 
 is dark energy (or a cosmological constant)\, which drives the accelerated
  expansion of the universe and 27% is dark matter\, an additional matter c
 omponent which clumps together to form large halos around visible galaxies
 . These two dominating components of the universe have only been observed 
 through their gravitational effects\, and both represent the failure of ou
 r standard models of particle physics and gravity to explain cosmology fro
 m a fundamental physics standpoint.\nIn this talk I will focus on the intr
 oduction of new light scalar fields which have been suggested as possible 
 explanations for dark matter and the accelerated expansion of the universe
 . I will show examples of the unusual phenomenology that can arise in such
  theories\, and explain why properties of macroscopic objects\, such as de
 nsity and compactness\, are important in understanding how to detect them.
   I’ll then show how this leads to new opportunities for precision labor
 atory measurements to shed light on this type of new physics.
