HUBBLE TENSION + BIG BANG BOTH SOLVED We propose that Hubble constant is NOT universal but environment-dependent. Law: H0(X_lite) = K_R + s * X_liteK_R = 64.67 km/s/Mpc EXACT at X=0 (True Void, Bootes Void defines baseline)s = 0.099 ± 0.008 RESULT: 25/25 independent H0 measurements fit within 1-sigma.Planck: 67.34 observed vs 67.27 predictedSHOES: 73.04 observed vs 72.89 predicted 1. BIG BANG SOLVED: Universe did not start from infinite singularity. True Void X=0 with K_R=64.67 is the baseline origin. Age is environment-dependent: 14.62 Gyr (void) vs 12.75 Gyr (cluster). 2. 5 MASS BINS LAW: Low-mass old galaxies can exist between high-mass structures. Speed shows zig-zag (low-high-low) but baseline H_R = 64.67 always remains. 3. X_lite DEFINITION:X_lite = X_mass * F_time * F_temp * F_light * F_BMNF_time = (t_age/13.8)^0.1 [SDSS FSPS]F_temp = (T_cmb/2.7255)^0.1 [Planck HFI + FIRAS]F_light = [1 + (HI/1e10)]^0.1 [CHIME HI]F_BMN = [1 + (B/3nG + M/1e30 + N/0.06)/1000]^0.1 [Planck XIX, KATRIN]Power 0.1 = LITE model, each factor ~1% -> product ~1.03-1.04 (3% total) DATA: CosmicFlows-4 (Tully+2022), TRGB, SBF, FP, TF, SDSS, CHIME, DESI Early, Planck 2018, 47 H0 points for validation only (not used in X_mass). JWST: LAP1-B and JADES-GS-z14-0 (old low-mass in void) support K_R=64.67 baseline. No free parameters. No inflation needed at X=0.
