We disprove the separable C ∗ -algebraic spatial form of the Kadison–Kastler conjecture. For every ε > 0, we construct unital, norm-separable C ∗ -algebras on a common separable complex Hilbert space, with the same identity and Kadison–Kastler distance less than ε , that are not conjugate by any unitary. The two algebras have the same von Neumann closure.
