sci.hubble-distance Calculator
Calculates recession velocity and distance of a galaxy using Hubble's law: v = H₀ × d, where H₀ ≈ 70 km/s/Mpc. A galaxy 100 Mpc away recedes at ~7,000 km/s — the Hubble constant remains debated between CMB-derived 67.4 and local distance-ladder 73 km/s/Mpc.
Inputs
Redshift Z
