Whose law explains the redshift-distance relation in an expanding universe?
Quick Answer
Edwin Hubble’s. He showed in 1929 that more distant galaxies recede faster, now called Hubble’s law.
The Full Story
Edwin Hubble is credited with formulating the observational relation now called Hubble’s law. In 1929, he compared galaxy distances with their redshifts and found that recession speed increases with distance. This became a cornerstone of modern cosmology and evidence that the universe is expanding. The relation is often written as v = H₀d, where H₀ is the Hubble constant.
