Cosmic Origins

Origin of the Universe: The Big Bang by Dr. Christopher Impey. The scientific story of creation begins 13.7 billion years ago in a circumstance of incredible temperature and density, when all matter and radiation was contained in a region smaller than an atom. The big bang is now a mature theory, with a web of observational evidence supporting it; and the size, shape and age of the universe have been measured with impressive accuracy. This talk will tell the story of how an iota of space-time turned into a vast cold universe of 100 billion galaxies.

Dr. Christopher D. Impey, Distinguished Professor, Astronomy/Steward Observatory, The University of Arizona.
