This book examines the experimental measurements that are used to verify Einstein's theories of special and general relativity and his ideas about relativistic cosmology that eventually became the Big Bang. It examines the differences between the calculations of Einstein's metaphysical assumptions and the physical principles of the Living Cosmos. The Living Cosmos makes the same astronomical measurements as relativity but does so from perspectives that are upside down, backwards, and inside out from standard model Big Bang theories. The book presents new principles for atomic physics and gravity based on the physical measurements of mass, space, time, and gravity instead of relativity's metaphysical assumptions of equivalent force and "pure" photon energy. The creation of the Living Cosmos is revealed as a sequential, non-synchronous, evolutionary process in which the galaxies were created first, then the stars, and finally our atomic matter. The true and absolute nature of gravity experiments is revealed.
