Persia String Theory: Galactic Rotation, Quantum Spectra, and Time without Dark Matter

I introduce Persia String Theory, a self-regulating framework in which dark matter is replaced by tension-bearing bosonic strings (Persia Strings) permeating the universe. Galactic rotation curves emerge from two universal terms, modified by a natural cut-off (e^{-r_c/r}) that suppresses the extra force at small radii. Fitting to 171 SPARC galaxies yields a median χ²_red = 3.13, with 110 galaxies having χ²_red < 5. The same strings explain the hydrogen spectrum without the Schrödinger equation (E_n = -13.6/n² eV), while a dynamic snap threshold τ_max(ρ) makes the theory scale-dependent. I predict impulsive gravitational waves (Kourosh Snap) from string breakage, with strain amplitude h₀ ~ 10⁻²⁰ - 10⁻²¹ and width σ ~ 10⁻⁶ s, accessible to next-generation detectors. Dark matter is unnecessary at all scales.
