Understanding the Big Bang Theory
The Big Bang Theory is an astronomical model that describes the universe observable to human senses. It provides detailed insights into the universe's origins, from its early formations to its contemporary evolutions.
The Big Bang Theory explains the universe's expansion from an extremely high density and temperature state, providing a detailed explanation of observed phenomena, radiation, an abundance of light elements, and large-scale structures.
What does the Big Bang Theory propose?
According to the Big Bang Theory, the universe cooled down enough after its initial expansion phase to allow the formation of particles that later became atoms. Primordial elements like Hydrogen, Helium, and Lithium condensed through gravity to form early stars and galaxies. In simple terms, the universe inflated into a cosmic system 13.8 billion years ago, resulting in the formation of the galaxy and solar system as we know it.

Common Misconceptions about the Big Bang Theory
A common misconception about the Big Bang Theory is that it provides a complete origin of the universe. However, it does not describe the energy, time, and space involved in the creation of the universe. It only explains how the universe emerged from its initial high-temperature state. It would be incorrect to compare the Big Bang Theory to everyday objects, especially in terms of size. The theory only describes the size of the observable universe, not the universe in its entirety.
Accurate interpretation requires the use of general relativity. While simpler Doppler effect arguments yield nearly identical results for nearby galaxies, interpreting the redshift of more distant galaxies based on simple Doppler redshift treatments can lead to confusion.
