Historical overview
... It follows that the Universe has a finite age: the time between the Big Bang and the present. IF the expansion velocity was constant throughout the history of the Universe to the same value measured now (v=d/t=H*d with H0=70 km/s/Mpc), then the age of the Universe is 1/H0= 14 billion years (but see ...

Theories
... The most commonly accepted theory today of the formation of the universe is the Big Bang Theory. The theory states that the universe originated sometime between 10 billion and 20 billion years ago from an enormous explosion of a small volume of matter at extremely high density and temperature. ...
