The Big Bang is originally a scientific theory given by George Le maître in which he told us about the origin and evolution of our known universe.
The Big Bang theory is very easy to understand it says that about 13.8 billion years ago our whole universe originated from a single point.
The Big Bang theory was given by Georges Le maitre in 1927.He is originally a Priest as well as scientist from profession, he was from Belgium. Georges didn't named it the Big Bang theory, he named it the hypothesis of the primeval atom
The name Big Bang was given by Fred Hoyle, an English Astronomer, during a BBC radio broadcast in 1949.
Fred Hoyle coined the term Big Bang but he always fought in favour of the Steady State Theory and he never supported the concept that the universe starting from a single point.
In 1929, Edwin Hubble discovered that all the other observable galaxies were moving away from our Milkyway.
Edwin Hubble's observation that our universe is still expanding. This make all scientist to believe that at one time all the galaxies in the universe must have been close .
Cosmic microwave background radiation is thought to be the electromagnetic radiation from the Big Bang and it was discovered and confirmed by Robert Wilson and Arnold Penzias in 20 may 1964, which then propelled the Big Bang theory as the leading theory of the origin and evolution of our observable universe.
The chronology of the universe according to the Big Bang theory has five states, and they are the very early universe, the early universe, dark ages/large-scale structure emergence, the universe as it appears today and the far future.
Cosmology, a branch of astronomy, is which we study about the origin, evolution and possible future of our universe.A cosmologist is the name of a persons who studies cosmology.
Other theories of the evolution of the universe are the Big Bounce, the Steady State Theory and the Oscillating Universe Theory.
