SUMMARY:Confronting the Dark Energy Crisis in Fundamental Physics\, Ph
 ysics Department Colloquium\, Christopher Stubbs\, Harvard University\
 , Physics and Astronomy
DESCRIPTION:The best evidence we currently have for physics beyond the
  standard model comes from astrophysical observations: Dark Energy (re
 pulsive gravity in the vacuum!) \, Dark Matter (ordinary matter is a m
 inority component of the mass budget of the Universe)\, and even the c
 osmic abundance of matter over antimatter are each indications of shor
 tcomings in our understanding of basic physics. I will describe our ef
 forts to understand the nature of the Dark Energy\, and why this parti
 cular problem merits our collective attention. I'll also present the s
 tatus of PanSTARRS and the Large Synoptic Survey Telescope (LSST)\, tw
 o ambitious ground-based optical systems that will provide new capabil
 ities for studying diverse topics in astronomy and astrophysics\, and 
 fundamental physics.
