Understanding the Big Bang Model: A Brief Overview

Explore the Big Bang model, detailing the universe's explosive origin and cosmic evolution.

0 views

The Big Bang model proposes that the universe began as an extremely hot and dense point around 13.8 billion years ago. It expanded rapidly in a cataclysmic event, leading to the formation of matter, galaxies, and other cosmic structures. The model explains the observed universal expansion, cosmic microwave background radiation, and abundance of light elements. This framework is foundational in understanding the evolution and large-scale structure of the universe.
