Unified Field Theory: A Higher-Dimensional Projection Framework

TitleUnified Field Theory: A Higher-Dimensional Projection Framework AuthorLance Thomas DavidsonORCID: 0009-0006-1245-1644 Affiliation: Independent Research Upload TypePreprint Publication Date2026-03-10 DescriptionThis work presents a unified field theory in which all observable physical phenomena - gravitation, quantum mechanics, cosmic expansion, and thermodynamic evolution - arise as projections from a higher-dimensional bulk spacetime undergoing dynamical dimensional collapse.The framework is constructed from a single total action functional and organises all physics into a strict seven-layer hierarchy: geometry, matter/quantum, bulk, dimensional collapse, cosmic expansion, thermodynamics, and observer geometry. Each layer feeds deterministically into the next through an explicit dependency chain, culminating in one closed-form master observable energy equation that encodes the full energy content of the observable universe. First Principles FrameworkNew structural operators are introduced, including the dimensional collapse factor C of theta phi t, the bulk projection operator P bulk, the time-cleavage operator T cleave, and the observer bias function A obs of theta phi. Their consistent product structure generates all observable physics directly from higher-dimensional first principles under a unified Lagrangian formalism.The model recovers general relativity and standard quantum field theory in the appropriate limits while providing a geometric mechanism for cosmic acceleration and large-scale structure formation driven by anisotropic collapse. Full mathematical derivations, dependency architecture, and the complete field equation system are provided.
