Authors: H. D. Zeh

Comments: 10 pages, 1 figure, Latex - Invited paper for a special Einstein issue of Physics Letters A

The existence of spacetime singularities is irrelevant for the irreversible appearance of black holes. However, confirmation of the latter's unitary dynamics would require the preparation of a coherent superposition of a tremendous number of appropriate ``Everett worlds''.
