Abstract Contemporary physics relies on the assumption of a spin-2 graviton to explain the attractive nature of gravity, leading to unresolved inconsistencies in quantum field theory. This paper proposes a novel framework, "The Universe Force & Mirror Universe Unified Theory, " which posits that all fundamental forces are phase transitions of a single primary spin-1 "Uniparticle, " governed by varying energy densities. To resolve the inherent quantum repulsion of spin-1 force carriers among identical masses, we introduce a symmetric 5-dimensional (5D) spacetime bulk containing a parallel "Mirror Universe" composed of negative mass (-m) and negative energy (-E). Through this 5D framework, gravity naturally manifests as an attractive force within identical spacetime boundaries (+m +m and -m -m), while the interaction between the positive and negative universes remains strictly repulsive. Furthermore, this model provides a novel mechanism for Dark Energy, explaining it as the repulsive influx of negative energy via black hole-white hole bridges. Ultimately, the theory predicts a state of universal enthalpy balance, culminating in a mathematically neutral, zero-energy state.
