What was the Universe like from the earliest phases immediately after
the Big Bang to the present day? This lecture reviews the physics of
matter, and follows the evolution of the expanding Universe from the
first instants after the Big Bang, when all 4 forces of nature were
unified in a single grand-unified superforce until the emergence of the
visible Universe we see around us today. Recorded 2006 March 1 in 1008
Evans Laboratory on the Columbus campus of The Ohio State University.
