GENERAL KNOWLEDGE

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.

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. It didn’t occur in an already existing space. Rather, it initiated the expansion-and cooling-of space itself.

Detailed explanation-3: -Today, the consensus among scientists, astronomers and cosmologists is that the Universe as we know it was created in a massive explosion that not only created the majority of matter, but the physical laws that govern our ever-expanding cosmos. This is known as The Big Bang Theory.

Detailed explanation-4: -The Big Bang theory is an explanation of the early development of the Universe. According to this theory the Universe expanded from an extremely small, extremely hot, and extremely dense state. Since then it has expanded and become less dense and cooler.
