Galaxy A has a greater cosmological redshift than Galaxy B. What does this imply about Galaxy A?

💡 Explanation:

According to Hubble's Law, a galaxy's recessional velocity ($v$) is directly proportional to its distance ($d$) from the observer ($v = H_0d$). Cosmological redshift is the measure of this recessional velocity, caused by the expansion of space itself. Therefore, a greater cosmological redshift implies a greater recessional speed and thus a greater distance from the observer.
