Detailed explanation-1: -In the first moments after the Big Bang, the universe was extremely hot and dense. As the universe cooled, conditions became just right to give rise to the building blocks of matter – the quarks and electrons of which we are all made.
Detailed explanation-2: -The evidence is overwhelming that the universe was very hot and very dense 10–20 billion years ago, and has been expanding and cooling every since.”
Detailed explanation-3: -The spherical volume of space which will become the observable universe is 42 million light-years in radius at this time. The baryonic matter density at this time is about 500 million hydrogen and helium atoms per m3, approximately a billion times higher than today.
Detailed explanation-4: -Long ago, the universe was smaller, denser, and hotter.
