DESCRIPTION:Though the observed CMB is at very low energy\, it encodes ult
 ra high-energy physics in spatial variations of the photon temperature and
  polarization fluctuations. This effect is believed to be dominated by the
  initial quantum state of the Universe. �I will describe the first theor
 etical tools by which to construct such a state from fundamental physics. 
 �There are three specific observational effects this initial state will 
 produce: a ringing signal in the power spectrum of quantum field fluctuati
 ons\, enfolded type of non-Gaussian fluctuations\, and a calculable primor
 dial gravitational wave background. �We will soon be able to compare the
 se predictions against experiment\, allowing one to rule out classes of qu
 antum gravity models. Now is the critical time to undertake such investiga
 tions\, with a number of ongoing and planned experiments such as WMAP\, Pl
 anck\, and CMBPol poised to collect a wealth of precision data.\n\nhttps:/
