Big Bang

Summary
 A  Big Bang  is a cosmic event that is said to have lead to the creation of the universe. The essential idea is that the universe has expanded from a primordial hot and dense initial condition at some finite time in the past and continues to expand to this day. Observational evidence for the expansion of the universe came first from Edwin Hubble's 1929 discovery that galactic distances are proportional to their redshifts. Since the universe is seen to be expanding today, theoretical cosmologists can make detailed predictions of the universe's denser and hotter past.

Within Fiction a Big Bang is treated as a massive burst of energy or a expansion of Time and Space itself. Usually a Big Bang is considered atleast Universe Level if replicated by a Fictional Character (However some special cases can arise)
