Universe

The Universe is the location of many of the Doctor's adventures. The universe is infinite in space and constantly expanding. (DW: Genesis of the Daleks). It was created roughly 14 billion years ago during the Big Bang and will continue for at least another 10 billion years (any further study is stopped by the Time Spiral). Oddly enough, the universe has already passed the point of heat death, but most of the entropy has been vented into E-Space. (DW: Logopolis'')

Other Locations

 * Pre-Universe: Before the regular universe, there was another one. Several beings were able to survive that universe's destruction, such as The Beast and the Old Ones.
 * Alternate Universes: There are a variety of Alternate Universe, ranging from similar parallel dimensions (such as Pete's World and Inferno Earth) to unusual pocket dimensions (such as the Land of Fiction or Yssgaroth's Universe).
