Detailed explanation-1: -Around 13.7 billion years ago, everything in the entire universe was condensed in an infinitesimally small singularity, a point of infinite denseness and heat. Suddenly, an explosive expansion began, ballooning our universe outwards faster than the speed of light.
Detailed explanation-2: -The Short Answer: The big bang is how astronomers explain the way the universe began. It is the idea that the universe began as just a single point, then expanded and stretched to grow as large as it is right now-and it is still stretching!
Detailed explanation-3: -The universe came into being around 13.8 billion years ago with the Big Bang. At that time, a hot, dense fog of radiation and elementary particles wafted in space, which was rapidly expanding.
Detailed explanation-4: -From the moment of the Big Bang up until about 3, 000 years after (the radiation-dominated era), the density of radiation in the Universe was greater than the density of matter. However, in an expanding Universe, the radiation density falls faster than the matter density and the Universe became matter-dominated.
