Big Bang  

Definition

  • The Big Bang is the event in which, according to standard modern cosmology, the Universe came into existence some 12 to 15 billion years ago. It is sometimes described as an "explosion;" however, it is wrong to suppose that matter and energy erupted into a pre-existing space. Modern Big Bang theory holds that space and time came into being simultaneously with matter and energy. The possible overall forms that space and time could take – closed, open, or flat – are described by three different cosmological models.
