Explain the main components of the Big Bang The... - SS2 Physics Space Physics and Astrophysics Question

The Big Bang Theory states that the universe originated from a singularity and has been expanding ever since. The main components of the theory are as follows:

-       Singularity: The universe started as an infinitely small, hot, and dense point called a singularity.

-       Expansion: The universe is continuously expanding, with galaxies moving away from each other.

-       Cosmic Microwave Background (CMB): The CMB is a faint, uniform radiation discovered in 1965, which is considered the afterglow of the Big Bang. Its presence and characteristics provide strong evidence for the Big Bang Theory.

-       Redshift: The observation of redshift in the light coming from distant galaxies indicates that they are moving away from us, supporting the idea of an expanding universe.

-       Abundance of light elements: The abundance of light elements such as hydrogen and helium in the universe matches the predictions made by the Big Bang Theory.
