We construct a universe UH from three observations and zero free parameters. In 14 algebraic steps, UH produces the electron mass (mₑ = 0. 51100 MeV, exact), the cosmological constant (ΛℓP² = 2. 85 × 10⁻¹²²), the Hubble constant (H₀ = 67. 3 km/s/Mpc), the weak mixing angle (sin²θW = 3/13, 0. 001%), and the strong coupling (αₛ = 2/17, 0. 3%). All agree with current measurements.
