EVERYDAY SCIENCE

Detailed explanation-1: -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. A few millionths of a second later, quarks aggregated to produce protons and neutrons. Within minutes, these protons and neutrons combined into nuclei.

Detailed explanation-2: -According to NASA, after inflation the growth of the universe continued, but at a slower rate (opens in new tab). As space expanded, the universe cooled and matter formed.

Detailed explanation-3: -Energy of the void Since the 1990s, scientists have understood that the expansion of the universe is speeding up; the space between galaxies is widening faster now than it was billions of years ago.

Detailed explanation-4: -In the matter-filled Universe, the other galaxy would get farther and farther away from you as time went on, but it moves away from you more slowly in the process. Gravity works to counteract the expansion, failing to stop it but succeeding in slowing it down.
