4/22/2009 - First Things in the Universe

Tom Abel, Kavli Institute for Particle Astrophysics and Cosmology Laboratory, Stanford University

The first structure to form in the Universe can now be predicted from ab initio simulations starting with the known initial conditions of our Universe. What is found is a rich history with massive stars, black holes, UV radiation, and hydrogen molecules among others playing significant roles. Using supercomputer simulations allows us to visually show the origin of the first stars, their demise and impact on their future, which is our past, in the Universe' first billion years.
