Are the answers cosmologists seek much simpler than we think? And can we explain the origin of the universe without inflation?  Here today to share his bold new theory is the renowned physicist and cosmologist Neil Turok. Neil, who specializes in mathematical and early-universe physics, is the Higgs Chair of Theoretical Physics at the University of Edinburgh and Director Emeritus of the Perimeter Institute for Theoretical Physics. Recently, he’s been getting a lot of attention for proposing a simpler, more testable cosmological model that replaces inflation with a CPT-symmetric Mirror Universe, explaining dark matter, cosmic flatness, and density variations without adding unnecessary complexity.
