Detailed explanation-1: -The American astronomer Edwin Powell Hubble reported in 1929 that the distant galaxies were receding from the Milky Way system, in which Earth is located, and that their redshifts increase proportionally with their increasing distance.
Detailed explanation-2: -In one of the most famous classic papers in the annals of science, Edwin Hubble’s 1929 PNAS article on the observed relation between distance and recession velocity of galaxies-the Hubble Law-unveiled the expanding universe and forever changed our understanding of the cosmos.
Detailed explanation-3: -By studying the light emitted from various galaxies, Hubble discovered that the light appeared displaced toward the red end of the spectrum. It became apparent that our universe was ceaselessly expanding outward, and all galaxies housed within it were moving away from one another.
