Time Machines, the Multiverse and Other Fantasies
It is our everyday life experience that we re-visit previous places. We take it for granted that we always do so at later times. Even with the wonders of Special Relativity, when we considered the experiences of Alicia and Beatrice in Chap. 3, we saw that Beatrice re-visited her old home at a later time for her and the re-visit was at a much later time for Alicia, so much later in fact, that she was no longer a member of the living.
