For such a pseudo-euclidean space-time, the determinant of the metric tensor components g is negative, so that the typical pseudo-scalar g½ (a scalar density) is a pu ...

... It has been suggested that once two atoms, for example, become entangled in a way that they can be described by a single wave function, and once they have separated, they can still be described by this single wave function, even at infinite distances (Carson, 2000).
