History of Universe: Past to Present

In the present study, we throw light on the chronological development of the universe. The universe grows from being fraction of an inch to the present day accelerating universe. The universe consist of all matter and space including stars, galaxies, planets and space between them. A number of observations shows that the present day universe is in accelerating phase. The reason for this accelerating expansion is still unknown to cosmologists and physicist. The universe starts from the explosion of a single point of infinite density and experienced inflation for a very short period of time in the early universe called inflation. Then the universe shows decelerated expansion in medieval era and again the present day universe is in accelerating phase
