Webb26 aug. 2024 · For nearby galaxies, receding at non-relativistic velocities, the approximate relation between the recession velocity of the light source, V, and the redshift, Z, is linear: V = C x Z (4) C represents the speed of light, and recession velocity is expressed in fractions of the speed of light. Webb17 mars 2015 · 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. It inaugurated the field of observational …
