Relativity and Quantum Mechanics are not what physicists think they are. They are not physical theories; they are mathematical models of the observers’ experiences and measurements—of the contents of consciousness. They relate physical phenomena to observers and arbitrary frames, not to Cosmic entities or frames. Since they do not model the Cosmos, they cannot be used to theorize about Cosmic entities or processes; attempting to do so produces paradoxes and confusion. These subjectivistic models and the Science of which they are archetypes are products of Berkeleyan subjective idealism and Machian positivism—archaic spiritualistic-idealistic theories of the nature of consciousness and its contents. In order to understand the Cosmos we must relate all physical phenomena to the causal substrate—to Cosmic space. When we do so, gravity immediately appears to be the flow of inertial-electromagnetic space into all matter. The flow’s acceleration (GM/r^2) produces gravity’s ballistic effects and its velocity (√(2GM/r)) produces gravity’s electromagnetic ("relativistic") effects. This theory directly implies plausible mechanisms for black holes and for the galaxial rotation and recession anomalies (a.k.a. "dark matter" and "dark energy"). Its quantized space allows us to theorize about the microcosmic entities and processes that underlie the hierarchical evolution of complexity. Space theory restores the Cosmos and causality to both physics and philosophy.
