The Bing Bang is a well-tested scientific theory which is widely accepted within the scientific community because it is the most accurate and comprehensive explanation for the full range of phenomena astronomers observing in the universe.

BANG THEORY

Our Universe was created when a tiny, super-dense, super-hot mass exploded and began expanding very rapidly, eventually cooling and forming into the stars and galaxies. This event happened approximately 13.7 billion years ago.

 

PULSATING (OSCILATING) THEORY

Some 13.7 billion years ago a great explosion occurred in the Universe and the universe has been expanding ever since. It is likely to go on expanding for 29 billion years more, when gravitation will halt further expansion. From then on, all matter will begin to contract or collapse upon itself in a process known as Implosion. This will go on for 41 billion years compressing matter into an extremely super dense state and then it will explode once again.

 

STEADY STATE THEORY

This theory depict universe with no beginning and end. New matter in the form of hydrogen takes place by the combination of atomic particle in the space between galaxies, where the old matter in receding
