Explanation:
Detailed explanation-1: -The age of the universe based on the best fit to Planck 2018 data alone is 13.787±0.020 billion years. This number represents an accurate “direct” measurement of the age of the universe, in contrast to other methods which typically involve Hubble’s law and the age of the oldest stars in globular clusters.
Detailed explanation-2: -Lightyears. A common method for measuring distance in space is to measure how far light travels in one year: known as a lightyear, which is around 9.5 trillion km.
