THE LIGHTCONE AS A CLOSURE BOUNDARY Minimal Relational Orientation, Grade-Dual Lorentzian Structure, and Null-Rank Protection

Foundational Quantum Mechanics · Spacetime Invariants · Geometric Algebra The lightcone is normally introduced within an already Lorentzian spacetime as the null locus ds² = 0. Within special relativity, relativistic field theory, and quantum electrodynamics, this structure separ...
