Okay then. Then that means:


 * Parallel reality or alternate timeline
 * A reality created when an event with several possible outcomes leads to the creation of multiple realities or universes with their own timeline and different outcome to the same event, like branches if a tree.


 * Alternate reality
 * A wholy different reality whose origin has little connection to our own universe's.

There's one problem though - if changing the timeline results in the creation of another one, doesn't that actually remove all the issues the Doc has with time travel in The Angels Take Manhattan and his inability to save Amy and Rory?
