Explain why Hubble’s parameter, with its value today called Hubble’s constant, is not actually a constant.
ANSWER:
Hubble's law states that the recessional velocity of the distant galaxy is directly proportional to their distance of the galaxy.
Where H0 is the Hubble's constant and its present value is 70 km/s/Mpc.
