Explanation:
Detailed explanation-1: -The Hubble constant is calculated by comparing distance values to the apparent recessional velocity of the target galaxies-that is, how fast galaxies seem to be moving away. The team’s calculations give a Hubble constant of 69.8 km/sec/Mpc-straddling the values derived by the Planck and Riess teams.
Detailed explanation-2: -The Hubble Constant (Ho) is one of the most important numbers in cosmology because it is needed to estimate the size and age of the universe. This long-sought number indicates the rate at which the universe is expanding, from the primordial “Big Bang."
