Explanation:
Detailed explanation-1: -According to the Big Bang theory, which proposes that the universe is roughly 13.8 billion years old, all matter and energy were at one time compressed into a single microscopic point. This point then exploded outward in all directions in a rapid expansion.
Detailed explanation-2: -The Big Bang theory says that the universe came into being from a single, unimaginably hot and dense point (aka, a singularity) more than 13 billion years ago.
Detailed explanation-3: -Most of the hydrogen and helium in the Universe were created in the moments after the Big Bang. Heavier elements came later. The explosive power of supernovae creates and disperses a wide range of elements.
