E/m = S²/T² — The Mass-Energy Spacetime Ratio

An independent dimensional-analysis framework arrives at the same structure as Beck Physics from a completely different starting point. E/m = S²/T² means every particle IS its spacetime velocity ratio. Three equivalent forms: √E/√m = S/T (geometric mean = Psi-throat amplitude), E/S² = m/T² (energy density in space balances mass density in time). Fermion/Tachyon mirror symmetry across the c-diagonal. Tachyons are pre-causal — received before emitted — the particle-language description of the ER bridge. Wave-particles extend into new spacetime via both curved (d operator, gravity) and straight (u operator, quantum) extensions simultaneously. Four independent paths — dimensional ratios, Beck algebra, Foam Field Equation, tachyon pre-causality — all converge on the same fixed point.
