As we researched content for the issue I came across two books, The Search for Superstrings, Symmetry, and the Theory of Everything and In Search of the Multiverse: Parallel Worlds, Hidden Dimensions, and the Ultimate Quest for the Frontiers of Reality. Reading those books made me want to speak with the author, John Gribbin about higher dimensions. I then discovered that he was also the author of a book that had a big influence on me when I read it some decades ago, The Search for Schrodinger’s Cat: Quantum Physics and Reality. John is the author of many scientific books as well as novels of science fiction. His interview gives us a window into some of the current thinking around the possibility that we live in a multiverse.
