Manifesto on the Physical Nature of Time Asymmetry

This work addresses the time arrow problem - the fundamental distinction between past and future despite the temporal symmetry of physical laws. It proposes that the weak interaction can be regarded as the primordial physical mechanism giving rise to time’s arrow, as it is uniquely associated with the violation of fundamental symmetries. In this model, fundamental interactions are treated as minimal quanta of change based on the transfer of energy and momentum, where energy defines the magnitude of change and momentum determines its direction. The weak interaction thus represents the first empirically confirmed source of temporal asymmetry, while the possibility of an even deeper universal meta-interaction remains open.
