"Taking the Universe's Baby Picture"

David Spergel
Princeton University

Thursday, November 12, 2003
3:30 p.m.

Main Building Auditorium
3141 Chestnut Street
Philadelphia, PA 19104

David Spergel By observing tiny fluctuations in the microwave background, the leftover heat from the big bang, cosmologists can address many of the most important questions in cosmology: How old is the universe? What is the shape and size of the visible universe? Is most of the universe composed of atoms? When did the first stars form? What happened during the first moments of the big bang? David Spergel will describe recent observations by NASA's Wilkinson Microwave Anisotropy Probe and show how these observations help answer these questions.
