CMB Observations and the Standard Model of the Universe



George F. SMOOT

LBL Berkeley and Chaire Blaise Pascal Paris



Résumé : Using our most advanced techniques and instruments we sift through relic clues and evidence to understand the events surrounding the birth and subsequent development of the Universe. A precision inspection and investigation of the Cosmic Scene along with careful analysis, discussion, and computer modeling have allowed us determine what happened over billions of years with amazing certainty and accuracy. Some of the findings are surprising and even shocking twists of plots. There remain even more mysteries to be solved. In spite of that we can tell the tale of the creation and history of the Universe and show key supporting evidence some of it from very early times including using the cosmic background light to provide a direct image of the embryo universe. This talk will be a review of the current state of cosmological observations based on the study of cosmic background radiation and the challenging issues still to be confronted.
