In three to five sentences, briefly describe how the big bang theory explains the origin and evolution of

Question

the universe

Answer 1

The big bang theory explains that the universe originated from a singularity, an infinitesimally small and dense point, around 13.8 billion years ago. This singularity rapidly expanded, creating the basic building blocks of matter, energy, and space itself. As the universe expanded, it cooled down, allowing matter to form, galaxies to develop, and stars to be born. The theory also accounts for the ongoing expansion of the universe and the observed cosmic microwave background radiation, which supports the idea of an initial dramatic event.
