  1. Density / critical density defines geometry

  2. The most recent Hubble diagram shows evidence of a cosmological constant or dark energy!

  3. 2004 results: Testing models Riess et al. 2004

  4. 2004 results: Testing models

  5. CMB fluctuation Spectrum Data from WMAP

  6. Evidence for a cosmological constant Loitering solutions

  7. The energy budget from: CMB, large-scale structure & Supernovae

  8. Ultimate fate of the Universe

  9. Problems for the Big Bang • What went Bang? • Why are there 3 spatial dimensions? • Did time have a beginning? • Why is the Universe so isotropic? • Why is the total density so close to critical? • What is the origin of the cosmological constant? • Why is the force of gravity so weak?
