Modulus Time: A Symmetrical Framework for the Directionality of Absolute Time and Cyclic Cosmology

This paper proposes a concept of Modulus Time, denoted as |T|, a framework where time is treated as a symmetric quantity with magnitude independent of direction. In contrast to the conventional concept of time, which flows only in the forward direction, Modulus Time integrates two symmetric directions, +T and -T, each corresponding to contrasting entropy evolution. This symmetrical property naturally suggests a cyclic cosmological framework, where the universe experiences phases of expansion with increasing entropy (+T), followed by contraction with decreasing entropy (-T), forming an indefinitely repeating cycle. We discuss the theoretical significance of Modulus Time, addressing the thermodynamic causality, the arrow of time, and contrasting entropic evolution.
