A Universe of Spaces: How quantum spacetime emerges from the spooky action hidden within Einstein's special relativity In the early years of quantum mechanics, Einstein expressed concerns about the meaning of the theory and its completeness. Despite the many intervening decades of scientific success, many of those concerns are still alive today in the field of quantum foundations. Prominently, the well-established phenomenon of quantum nonlocality (‘spooky action at a distance’) seems to simply ignore Einstein’s theories of relativity. The resolution of this longstanding conflict between quantum and spacetime ideas is the major theme of this book. Based on established principles, Einstein’s relativity is reinterpreted as describing multiple spaces, held together by a quantum glue. Although it may appear that we shared a single space, we actually live within a quantum multispace. This new approach fully integrates relativity and quantum mechanics, and provides clear and deep explanations for the weirdness of quantum mechanics. This new quantum spacetime is a stepping stone to a theory of quantum gravity - the holy grail of theoretical physics.
