The big bang theory is the prevailing cosmological model for the universe from the earliest known periods through its subsequent large-scale evolution the model describes how the universe expanded from a very high-density and high-temperature state, and offers a comprehensive explanation for a broad range of phenomena, including the abundance of light elements, the cosmic microwave background. The big bang theory is the major explanation of how the universe began observations show that the universe is expanding, and the galaxies seem to be moving out from a specific point by interpolating backward, it is estimated that all of the galaxies in the universe started with an explosion some 137.

Big bang theory describes the origin of the knowable universe and the development of the laws of physics and chemistry some 15 billion years ago during the 1940s russian-born american cosmologist and nuclear physicist george gamow (1904-1968) developed the modern version of the big bang.

Astronomy is the branch of science that deals with celestial objects, space, and the physical universe as a whole it is concerned with the evolution, physics, chemistry, meteorology, and motion of celestial objects, as well as the formation and development of the universe.
The red line in the figure on the left shows that according to big bang theory, the universe had a radius of more than 10-10 metres at 10-45 seconds after the big bang since the speed of light travels at 3×10 8 m/s, information could only have travelled ~3×10 -37 metres during this time. The work of the eminent physicist, dr sheldon cooper of hit tv show the big bang theory, has served as the springboard for the creation of a new chemical compound - baznga those familiar with dr cooper will know that his use of the phrase 'bazinga' tends to be associated with a jest or jape.
