Webbseparable metric spaces”—such a space is a separable metric space which contains a homeomorph of each separable metric space. A less well-known result of metric topology is that there are universal separable metric spaces up to isometry; that is, there are separable metric spaces which contain an isometric copy of each separable metric space.
