We show that it is consistent with Zermelo–Fraenkel set theory with the axiom of choice (ZFC) that there is a simple nuclear
nonseparable
C∗-algebra, which is not isomorphic to its opposite algebra. We can furthermore guarantee that this example is an inductive
limit of unital copies of the Cuntz algebra
O2 or of the canonical anticommutation relations (CAR) algebra.
