After reviewing the notion of CPT symmetry, I will introduceourproposal that the state of the universe does *not* spontaneously violate CPT.Instead, the universe after the big bang is the CPT image of the universebefore it, both classically and quantum mechanically. The pre- and post-bangepochs may be thought of as a universe/anti-universe pair, emerging fromnothing directly into a hot, radiation-dominated era.
