Pete's World

Pete's World is the Doctor's name for an alternate universe and home to its own Cybermen which, the head of Cybus Industries, John Lumic had created.

Overview

The Doctor derived the name from Pete Tyler, that universe's version of Rose Tyler's father, who in her universe had died in 1987. Time apparently moved quicker in this universe than in the usual ones, so that while mere months pass between his first (DW: The Age of Steel) and second encounter with inhabitants of the parallel Earth, three years had passed on Pete's World. (DW: Doomsday)

Until the the Doctor's clone came here, it apparently had no native version of the Doctor.

History

Timeline

2007

• 1 - The Doctor, Rose Tyler and Mickey Smith arrive in a parallel universe that the Doctor's TARDIS is catapulted into while travelling through the Time Vortex. The TARDIS is nearly destroyed by the impact. The Doctor gives away 10 years of his life to repair the TARDIS. The Cybermen are created by John Lumic and attack the United Kingdom. After meeting his parallel counterpart Ricky Smith and being inspired by his example, Mickey decides to stay in the alternate universe to take the late Ricky's place and help fight the Cybermen. (DW: Rise of the Cybermen / The Age of Steel)

circa 2010

• Mickey Smith returns to his original world and, disguised as a lab technician, investigates the Void Ship kept in Torchwood 1's headquarters. Jake Simmonds and Peter Tyler cross over into the Doctor's universe to stop the Cyberman invasion. Jackie Tyler meets the other version of Pete Tyler for the first time and decides to stay with him. Rose Tyler, Mickey Smith, Pete and Jake decide to return to the other world and Jackie to stay there.(DW: Army of Ghosts/Doomsday)

circa late 2010-11

• Rose joins the parallel version of the Torchwood Institute. Jackie and Pete conceive and child and Mickey apparently takes up residence with the Tylers (although there is no indication that Mickey's relationship with Rose has resumed). (DW: Doomsday)
• Soon after joining Torchwood and several months after Jackie becomes pregnant, Rose begins receiving what appears to be a message from the Doctor. With the support of her family, she travels to a remote fjord in Norway, Dårlig Ulv Stranden, where she is able to briefly make contact with the Doctor. Although she is able to tell him that she loves him, he is unable to respond properly before communication is lost. The exchange leaves Rose emotionally devastated. (DW: Doomsday).

circa 2013 or 2014

• At some point after Jackie Tyler gives birth, Rose and Torchwood begin detecting the onset of "The Darkness" - the after-effects of the detonation of the Daleks' reality bomb. They acelerrate their work on a device capable of transporting Rose back to her original Earth (presumably without the environmental impact of the previous device). This work is successful, and Rose makes several trips to her original Earth, where time is running slower and therefore is a couple of years in the past and before the detonation of the reality bomb. (DW: multiple episodes Season 4)
• After defeating the Daleks and preventing the reality bomb from detonating, the Doctor returns Rose and Jackie to the parallel Earth (presumably in their original timeline, which is ahead of their original Earth's). Also left behind is the Meta-Crisis Tenth Doctor, who begins a relationship with Rose. (DW: Journey's End.

Jackie does mention that Pete is on the nursery run, wether this is pre-school or daycare is never said, if it is pre-school it would have to be at least 3 years after the birth, placing the date in this world 2013 or 2014.
