The Big Bang Theory is a theory of how the universe, space, and matter came into existence.

About Big Bang Theory

The Big Bang Theory is commonly thought of as a theory concerning the origins of the universe. Contrary to ancient beliefs that the universe was infinite, or that it began when God created the heavens and the earth, the Big Bang theory attributes the universe's beginning to a tremendous explosion that occurred over 14 billion years ago. The theory was originally postulated by Edwin Hubble, for whom the Hubble Space Telescope is named. When Hubble discovered the rapidly expanding nature of the universe, it was a revolutionary concept that led him to believe that the entire universe must have started from a single point that violently exploded.

Astronomers have spent decades studying the Big Bang Theory, utilizing the fundamentals of observation and mathematics to somehow recreate a model of the event. Scientists rely on Albert Einstein's theory of relativity and his concepts about particles to aid in their understanding, and they continue on with Hubble's work of measuring the expansion of the universe. In fact, some question whether or not the universe will go on expanding forever, simply stop or completely move in reverse at some point causing another theory called The Big Crunch.''

Interestingly enough, an astronomer discussing a competing theory coined the term 'Big Bang'. In the late 1940s Fred Hoyle was on a radio show to talk about the Steady State Model, and referred to the expanding universe model as 'the big bang idea.' The term stuck, and has caused plenty of confusion since. Instead of the term Big Bang theory, a better term for the model of our universe would probably be the 'expanding-universe theory.' ''
