What Came Before the "Big Bang?"
"It is really a high density situation that we call the big bang, but there is really no explosion," says Freese. "There is no 'bang.' There is no singular point."
Katie Freese is a professor of physics at the University of Michigan, and the associate director of the Michigan Center for Theoretical Physics. Her work deals with a wide variety of topics in both theoretical cosmology and astroparticle physics. Her research is largely involved in trying to identify the dark matter and dark energy that permeate the Universe, and to build a successful model for the early universe immediately after the Big Bang.
