Big Bang

The Big Bang refers to the creation of the present Universe itself.

At least one Pre-universe existed before this one. (NA: The Pit, MA: Millennial Rites). The Beast existed and already had gotten imprisoned by the time of the Big Bang (DW: The Satan Pit).

An "empty void" (DW: Terminus) or a "dense monoblock of matter" (BBCR: Slipback) existed.


 * Perhaps the matter appeared in the void.

Matter then exploded outward in the form of hydrogen.(DW: Castrovalva). The Leptonic Era would follow. (DW: Time and the Rani)

Possible artificial causes

 * The Doctor speculated that the massive ship, Terminus had time jumped at some point, discharged its fuel and instigated the Big Bang before time jumping a second time back from the distant past. (DW: Terminus).


 * Contradicting this, a Time Lord from the High Council stated to the Doctor that the Vipod Mor, headed back in time to the creation of a galaxy, would overshoot and travel back to before the universe, thus causing the Big Bang. (BBCR: Slipback)

References to the Big Bang

 * A Time Lord told the Doctor that they (the Time Lords) had mastered transmat technology when "the universe was half its present size" (DW: Genesis of the Daleks').


 * The Time Lord said this to the Doctor on Skaro during an indefinite time period during the end of the Thousand Year War, which happened at the very latest, before the year 2157, by which time the Daleks already had interstellar spaceflight.


 * According to the Doctor, the creation of the universe occured 13,500,020,012 before a specific date in the early 22nd century, when he decided to celebrate. (NA: Transit)


 * We do not know if he counted the date in Earth or Gallifreyan years.


 * The Doctor implied that himself that had watched it happen, or at least that other sentient beings had done so (DW: Destiny of the Daleks).


 * The delusional Monarch, believing himself God, wished his ship to travel back to the Big Bang and witness himself creating the universe. (DW: Four to Doomsday)
