Explanation:

The big bang is a physical theory that explains how the universe we know came into being. This theory states that the universe was generated from a particle that has expanded and continues to expand today. all this expansion allows several galaxies to be scattered throughout space, in addition to allowing these galaxies to move away from each other.

The Big Bang theory also states that atomic nuclei existed at the beginning of the universe and that these nuclei must have left a trace of their existence as a detectable range of radiation. This can be proven by stating that uniform background radiation is detected in all directions.
