Unification of theories requires a postulate basis in common

A primary challenge of natural sciences in the new millennium is to cure the gap between metaphysics and empiricism – and puzzle out the obstacles to a unified theory and an understandable picture of reality. Antique science flourished via its strong philosophical impact but faded away due to the lack of supporting empirical science. The fast development of mathematical physics has led to the other opposite; theories are diversified, they are more like mathematical descriptions of observations; they provide precise predictions but lack a solid metaphysical basis and an understandable picture of reality. Anyway, modern science has increased our understanding of physics from elementary particles to cosmological structures and produced information that allows re-evaluation of the basis. By switching from an observer-oriented perspective to a system-oriented perspective, any local object is related to the rest of space and relativity appears as a direct consequence of the conservation of total energy in the system – without scarifying the absolute time and distance essential for human comprehension. Such a holistic approach has led to the Dynamic Universe theory (DU). After maturing for the last twenty-five years, DU produces precise, well-tested predictions for local and cosmological observables and an uncontradictory linkage to quantum mechanics.
