Hubble's Spiral Nebula Mystery

Astronomer Hubble began to focus his full attention on the cosmic exodus in 1928. By 1929 he had determined the distances to 24 galaxies, including the small and large Magellanic clouds. The most remote then judged to reside some six million light-years away. It looked like there was a direct relationship between how far a galaxy was and how redshifted it was. If,. and this was still an unsettled question, if the redshifts represented actual motion, then the farther away a galaxy was, the faster it was moving towards us.
