This is a complete preprint of the 9D-USTE (Nine-Dimensional Universal Space-Time Entropy Theory), centered on the fundamental K* primordial field. The work establishes a mathematically consistent and self-contained theoretical framework that unifies the origin of matter, mass, energy, and cosmic civilization. Based on nine-dimensional pure space, the theory derives the Lagrangian density, dynamical equations, and uses toroidal compactification to explain the high-dimensional origin of rest mass. A controlled energy-extraction mechanism is introduced via a Lagrange multiplier, while a dimensional entropy-scaling relation provides a rigorous physical resolution to the Fermi paradox. This paper is intended for permanent open access, academic archive, and open citation in theoretical physics, cosmology, and high-dimensional field theory.
