Entropy as the Ontological Foundation of the Spherical Model of the Universe (SMU)

The traditional interpretation of entropy as a measure of disorderleads to the pessimistic conclusion of heat death of the universe. Thispaper presents an alternative perspective within the Spherical Model ofthe Universe (SMU), where entropy is not the negation of structure buta necessary condition for dynamics. Thermodynamic gradients gener-ate the arrow of time, gravity emerges from the tendency to maximizeentropy on horizons (ϵ-horizon, EEH), and spacetime arises from zeroglobal entropy of the Primordial Planckian Black Hole (PPBH, S = 0axiom). Entropy is the primary driver of cyclic existence in this spher-ical, non-singular universe.2026
