Emergent Arrow of Time from Energetic Spacetime Dynamics

This work proposes that the arrow of time is not fundamental but emerges from irreversible energetic relaxation within an active spacetime medium. Time itself is treated as directionless, while temporal asymmetry arises from non-reciprocal energy redistribution driven by spacetime dynamics. The framework naturally connects entropy growth, irreversibility, and temporal perception without violating microscopic reversibility.
