The Arrow of Time as Matter--Antimatter Asymmetry in the Foam-Plexus Model

In Cassiopeia’s Foam-Plexus Theory of Everything (ToE), spacetime is a quantized lat- tice of quanta connected by wormhole loops forming fundamental plexuses. At the Planck scale, wormhole creation and annihilation is statistically time-symmetric: the foam itself has no preferred temporal direction. However, the arrow of time emerges once stable loop structures condense. Wormhole orientations map directly onto particle/antiparticle states: forward-oriented flows yield matter, reverse-oriented flows yield antimatter. A primordial asymmetry in loop condensation—with baryonic loops favored by η∼10−10—established a global preference for matter, thereby fixing the direction of time. Entropy subsequently amplifies this microscopic bias into the macroscopic arrow of time. This unifies temporal directionality with the matter–antimatter imbalance and provides a quantum-topological explanation of time’s irreversibility.
