馃幀 The Big Bang theory is the leading scientific explanation for the origin of the universe. It proposes that the universe began about 13.8 billion years ago from an extremely hot, dense state and has been expanding ever since. Rather than describing an explosion in space, the theory explains the rapid expansion of space itself, causing galaxies to move away from one another. Key evidence supporting the Big Bang includes the observed expansion of the universe, the cosmic microwave background rad
