Webz = ( 680 n m − 656.3 n m) / 656.3 n m = 0.036. Hubble's law, which says simply that a galaxy's velocity (or as is sometimes plotted, its redshift) is directly proportional to its distance, also tells us something important … WebHubble’s law, simply speaking, is the observation in physical cosmology that the movement of galaxies takes place away from the Earth at speeds that are proportional to their distance. In other words, the farther a galaxy is, the faster it would move away from Earth. Furthermore, the determination of the velocity of the galaxies takes place ... dr cobb falmouth
