Dark Matter, Dark Energy and Inflation

Dr. Michael S. Turner, Professor, Kavli Institute for Cosmological Physics, University of Chicago. Presented Feb. 15, 2011 Our current cosmological model describes the evolution of the universe from a very early burst of accelerated expansion (known as inflation) a tiny fraction of a second after the beginning, through the assembly of galaxies and large-scale structure shaped by dark matter, to our present epoch where dark energy controls the ultimate fate of the universe.
