Explanation:
Detailed explanation-1: -The big bang theory is the consensus cosmological framework for explaining the origin, properties, and evolution of the universe. According to this theory, the universe began almost 14 billion years ago in an extremely hot and dense state, from which it has cooled and expanded since.
