Detailed explanation-1: -The Big Bang Theory states that pre-existing matter was compacted into a hot and dense form and suddenly exploded into infinite, empty space. The Big Bang Theory is the scientific explanation of how the Sun, Earth, and the rest of the Solar System were formed at the beginning of time.
Detailed explanation-2: -Most astronomers use the Big Bang theory to explain how the universe began. But what caused this explosion in the first place is still a mystery. So, what has happened since the Big Bang? Since the Big Bang, the universe has been expanding.
Detailed explanation-3: -The universe formed from a central point. Which statement accurately describes the origin and expansion of the universe? As the universe continues to expand, it gradually gets warmer. Galaxies that are farther away are moving away more slowly.
