Future Convergence Theory: A Unified Framework for Delayed Choice, 4D Information Fields, and Quantum Decoherence

This paper proposes an extended formulation of Future Convergence Theory (FCT) that unifies three major components of modern theoretical physics: quantum delayed-choice experiments, four-dimensional information fields, and quantum decoherence. The theory introduces a novel function, \Lambda(T), representing future certainty, and explores how this function retroactively influences quantum states, information entropy, and energy distribution across spacetime. By incorporating \Lambda(T) into the evolution equations of wavefunctions and entropy, we show that future outcomes can dynamically shape the structure of the past. This framework offers a new interpretation of time and causality, suggesting that the future is not passively received but actively encoded into the informational fabric of the universe. We also discuss experimental possibilities, including quantum entanglement verification, AI-based prediction models, and cosmological observations. The theory aims to expand the foundations of physics by mathematically describing how the future may influence the past through higher-dimensional information dynamics.
