This work proposes a unified framework for the four fundamental forces based on quantum spin dynamics. The universe consists solely of matter and active space, which originate from convergent real space energy and divergent imaginary space energy, respectively. Therefore, the world is a 6D complex geometry, with 3D real space and 3D imaginary space which are symmetric. A primordial neutron cosmology posits that the universe originates from a neutron emerging from nothingness (zero net energy), with subsequent neutron decay (via Hawking radiation = β-radiation) generating protons and electrons. Accelerated cosmic expansion arises from continuous matter-space creation. Crucially, all forces reduce to a universal spin force: attraction/repulsion is governed by relative spin alignment (+1/-1) between particles or space vectors. This model offers novel interpretations of quark confinement, supersymmetry, and time’s origin while circumventing the graviton problem.
