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 heat energy is still here. It’s just that the “object” (the Universe) grown bigger so this energy had to spread through it. The more energy in a single point, the hotter it is.
Detailed explanation-3: -The Era of Recombination Until around a few hundred million years or so after the Big Bang, the universe was a very dark place. There were no stars, and there were no galaxies. After the Big Bang, the universe was like a hot soup of particles (i.e. protons, neutrons, and electrons).
Detailed explanation-4: -Astronomers have measured the proportion of hydrogen and helium scattered through our universe, and it matches the prediction perfectly. This was strong evidence that the early universe was hot as well as dense.
