Detailed explanation-1: -The big bang is how astronomers explain the way the universe began. It is the idea that the universe began as just a single point, then expanded and stretched to grow as large as it is right now-and it is still stretching!
Detailed explanation-2: -It is “well known” that Hoyle coined the term “big bang” in a pejorative sense, to make fun of the idea of an exploding universe, but what is well known is not necessarily correct. It is also generally assumed that the name was adopted by the cosmologists at an early stage and widely used in the controversy.
Detailed explanation-3: -The Big Bang is the name that scientists use for the most common theory of the universe, from the very early stages to the present day. The most commonly considered alternatives are called the Steady State theory and Plasma cosmology, according to both of which the universe has no beginning or end.
Detailed explanation-4: -A Belgian priest named Georges Lemaître first suggested the big bang theory in the 1920s, when he theorized that the universe began from a single primordial atom.
