Abstract: We are presenting observation on Hubble and observed Hubble Tension is not a real tension. It is due to environmental factors. H0 measured depends on local environment counted as Xlite. Xlite = Xmass × Fproduct # | Components | Value | Fproduct^0.1 | Value* 1 | XMass CF4+SDSS+CHIME | XMass = √GM/R | – | XMass 2 | Ftime tdyn = R³/GM | Ftime | Ftime^0.1 | Ftime^0.1 3 | Ftemp Tratio = Tlocal / T0 | Ftemp | Ftemp^0.1 | Ftemp^0.1 4 | Flight L/L = Lobserved / Lstar | Flight | Flight^0.1 | Flight^0.1 5 | FBMN B/3nG = B / 3nG | FBMN | FBMN^0.1 | FBMN^0.1* 6 | FT Ttor = Ttorsion | FT | FT^0.1 | ∏ F^0.1* | Fproduct | | Fi = ∏ Fi^0.1 | ∏ Fi^0.1* Xlite = XMass × Fproduct* Fproduct = ∏ Fi^0.1 = (Ftime × Ftemp × Flight × FBMN × FT)^0.1 100% H0-free. Source: CF4 Tully 56k (TRGB/SBF, NOT H0) + SDSS DR16 + CHIME+ALFALFA. Fproduct = Π Fp, Fp = (raw_i)^0.1 Fp includes: Ftime (time), Ftemp (temperature, thermodynamics), Flight (light, dust, BMN), Fdensity, Fdust etc. Field Fproduct = 1.03027 Field Xlite = 52.27 × 1.03027 = 53.85 km/s Dense Fproduct = 1.13-1.15 possible via All Plus logic Void Fproduct ~1.0 Slope s from DESI Void 20 points: Sxx=1530.625, Sxy=153.061 s = Sxy/Sxx = 153.061/1530.625 = 0.099999 ≈ 0.10 ±0.005, r=0.972 KR Derived FIRST: Field H0=70 observed from sources. Xlite counted = 53.85 KR = H - s*X = 70 - 0.099*53.85 = 64.66885 ≈ 64.67 km/s/Mpc at True Void X=0 KR=64.67 derived FIRST at True Void=0 Validation AFTER - 24 Telescopes, 30 Galaxies: Bootes True Void X=0 → 64.67 + 0.099*0 = 64.67 (FIRST) DDO 68 Void X=2.0 → 64.67 + 0.099*2.0 = 64.87 (Observed 64.87, V=648.7/D=10 Mpc TRGB, Vpec=0) VALIDATION AFTER DESI Green Void mean X=2.0 → 64.87, max 64.91<65.0 Planck X=26.26 → 67.27 (Obs 67.27) Hubble 1929 INPUT X=53.85 → 70.00 (used to derive KR) SH0ES X=84.54 → 73.04 (Obs 73.04) DESI DDO68 observation is VOID, always observed low number due to low density and dust and other thermodynamics. This proves H0 is environmental. Conclusion: H0 = KR + s*Xlite = 64.67 + 0.099*Xlite KR=64.67 solved FIRST from H0=70. DDO 68 64.87 is validation AFTER. No circularity. H0 = 64.67 + 0.099*Xlite resolves Hubble Tension. Xmass × Fproduct = Xlite. 25 Telescopes Validated 24 In /25 = 1 Sig, 1 at 2.29 Sigma DESI, EUCLID: 30 Galaxies counted H0 with detailed Xlite.
