Page "Parallel universe (fiction)" Paragraph 80

Doctor Who often features parallel universes as the basis of a plotline.

In the episode " Inferno ", from Doctor Who the Doctor accidentally travels to a parallel universe where Great Britain is a republic under a fascist leader.

In " Rise of the Cybermen ", the TARDIS falls out of the Time-Space Continuum, and dies, with the Doctor and his companions inside it.

The Doctor believes them to be in the Void, the infinite empty-space between the universes, where no time, space or energy exists.

It turns out, however, they fell into another universe ; a much more desirable option.

In this universe, Britain is a lot more technically advanced, with blimps almost replacing cars.

They find a way to revive the TARDIS and travel back to their own universe.

According to the Doctor in " Doomsday ", a new parallel universe is created by every decision made.
