Detailed explanation-1: -The Big Bang was the moment 13.8 billion years ago when the universe began as a tiny, dense, fireball that exploded. 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.
Detailed explanation-2: -The universe is about 13.8 billion years old, according to new research published in a series of papers by an international team of astrophysicists, including Stony Brook’s Neelima Sehgal.
Detailed explanation-3: -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. It didn’t occur in an already existing space. Rather, it initiated the expansion-and cooling-of space itself.
