Big Bang Theory

The Big Bang Theory is a scientific explanation for the origin and evolution of the universe. It posits that the universe began as an immensely hot and dense point approximately 13.8 billion years ago and has been expanding ever since. This theory is supported by various lines of evidence, including the observation of cosmic microwave background radiation, the abundance of light elements, and the redshift of distant galaxies, which indicates that the universe is still expanding. The Big Bang Theory describes not only the initial singularity but also the subsequent development of the cosmos, leading to the formation of stars, galaxies, and larger structures. It provides a comprehensive framework for understanding the history of the universe from its earliest moments to its current state.
