Famed particle cosmologist and University of Chicago Professor Michael Turner explained the dark mysteries of the universe at a U-M Physics Department public lecture May 17. The event, part of Great Lakes Cosmology VII, a regional meeting hosted by the Michigan Center for Theoretical Physics, drew a crowd of 250 people. Turner splits his time between the University of Chicago and the Fermi National Accelerator Laboratory. He is a member of the National Academy of Science, appears often on NPR and in the New York Times, and is coauthor of a classic cosmology textbook, “The Early Universe.” He said that while cosmologists know how the universe began, there is a dark side to the story. The same experiments that confirm the Big Bang suggest that the universe is filled with mysterious dark matter, and even stranger dark energy. (Photo by Per Kjeldsen)
