Detailed explanation-1: -Our universe was born about 13.7 billion years ago in a massive expansion that blew space up like a gigantic balloon. That, in a nutshell, is the Big Bang theory, which virtually all cosmologists and theoretical physicists endorse. The evidence supporting the idea is extensive and convincing.
Detailed explanation-2: -We do not know the exact age of the universe, but we believe that it is around 13 billion years-give or take a few billion. Astronomers estimate the age of the universe in two ways: (a) by looking for the oldest stars; and (b) by measuring the rate of expansion of the universe and extrapolating back to the Big Bang.
Detailed explanation-3: -During the Stelliferous Era, from 10, 000 years to 100 trillion years after the Big Bang, most of the energy generated by the universe is in the form of stars burning hydrogen and other elements in their cores. This era extends to Ten Trillion Trillion Trillion years after the Big Bang.
