IntroductionThe nature of time remains one of the most profound and unresolved questions in contemporary physics. Within the framework of general relativity, time is treated as a coordinate of the space-time continuum, with its direction determined by the geometry of the universe and entropic processes. In classical mechanics and most macroscopic phenomena, time is considered a linear and irreversible quantity. In contrast, quantum mechanics challenges this view by revealing nontrivial effects associated with measurement, superposition, and interference.Particularly intriguing are quantum delayed-choice experiments, which give rise to paradoxical interpretations concerning the potential retroactive influence of future events on past states. While prevailing interpretations—such as the Copenhagen framework or the multiverse hypothesis—offer partial explanations, none provides a complete ontological model that reconciles microscopic and macroscopic phenomena within a unified causal-temporal framework.This paper introduces an alternative hypothesis grounded in the cyclical nature of time and its informational essence. According to this hypothesis, the universe constitutes a closed informational system, devoid of parallel realities, in which the entire history—from the initial singularity to the end of thermodynamic time—manifests as a coherent informational configuration. The central feature of this model is a supermassive black hole that, following the culmination of cosmic expansion and entropic dissipation, begins to move backward in time. This reversal is not a playback of past events but a phase of energy accumulation, culminating in a renewed Big Bang.This conceptual framework reinterprets the arrow of time as an emergent property of a global informational structure, thereby eliminating the need for quantum randomness. The cyclical time hypothesis thus offers a potential foundation for a unified approach to time, causality, and the evolution of the universe.
