What fundamental relationship between redshift and distance did Edwin Hubble codify?
Answer
Hubble's Law: The farther away a galaxy is, the greater its redshift
Hubble's Law established the empirical link showing that almost all galaxies exhibit redshift, and this redshift increases proportionally with the galaxy's distance.
