Since the dawn of history, various cultures have imagined heaven and the abode of gods to be literally located in some part of the sky; and hell, to be in the interior of the Earth. From a modern scientific perspective, these were the earliest concepts of parallel universes and the idea of a multiverse, which is a serious area of research in cutting-edge physics today. This book presents a model, supported by scientific and metaphysical evidence, which validates this intuitive view. It appears that, after the death of the ordinary matter body, most human beings will indeed find themselves in an invisible (what science would call "dark") higher energy sphere which interpenetrates and shares the same spacetime landscape and gravitational field as the familiar visible form of planet Earth. Depending on the nature and composition of their bodies, they gravitate or levitate into particular "shells" in the relevant sphere - "higher" shells being coincident with the atmosphere, and beyond; and "lower" shells being within or below the crust of the ordinary matter Earth.
