The Future as Origin: Toward the Core of Being proposes a paradigm shift in cosmology, physics, and consciousness studies. Contrary to the conventional view of the universe expanding from a past singularity, this work argues that physical, cognitive, and structural systems evolve toward a future attractor of maximal coherence. Through an integration of quantum mechanics, general relativity, non-equilibrium thermodynamics, and complex systems theory, the book formulates a retrocausal framework wherein the future acts as a structural boundary condition that organizes present dynamics. Mathematical models—such as projected coherence fields, retroderivatives, and attractor-based metrics—are presented alongside simulations and experimental proposals. The theory predicts spontaneous convergence of physical and biological systems toward future-defined configurations, offering a falsifiable and testable foundation. This approach redefines time as a spiral of resonance, causality as structural alignment, and consciousness as a localized anomaly within a universe guided by an emergent final form. This volume lays the groundwork for a science of future coherence, blending rigorous mathematics with experimental proposals that challenge the unidirectionality of time and the classical notion of causation.
