Big Bang
Universal starting point
The Big Bang is the prevailing cosmological model for the origin of the universe—a rapid expansion from an extremely hot, dense state approximately 13.8 billion years ago.
The theory explains the observed expansion of space and the cosmic microwave background radiation: Evidence for the Big Bang includes the redshift of distant galaxies. (Lowercase big bang describes any explosive beginning.)
