How it works
d = v / Hâ‚€
Edwin Hubble found galaxies recede at speeds proportional to their distance — space itself is expanding. This simple estimator works for rough distances; precise cosmology needs the full expansion history.
Assumptions: Simplified linear Hubble law; Hâ‚€ default 70 km/s/Mpc. Not valid for very distant/high-redshift objects.
Reference: Hubble (1929); Planck Collaboration Hâ‚€ measurements
