Space loop

A space loop was a phenomenon similar to a time loop, but in space instead of time. The Third Doctor and the Master were once caught in a space loop when their TARDISes materialised inside each other. (DW: The Time Monster) It happened again when the Fourth Doctor toke measurements of the Master's TARDIS while it was in the form of a police box. However, this time it caused him and his comapnion, Adric, to go throw different versions of the control room until they finaly managed to exit back into their own. (DW: Logopolis)

The Eleventh Doctor and his companions Amy Pond and Rory Williams were also once caught in a space loop when the TARDIS accidentally materialised inside itself; caused by Rory dropping a crutial componet, to be installed in the console, when he looked up Amy's skirt from under the TARDIS's glass floor. The Doctor reversed it by using the Wibbly lever to create a controled explosion; the space loop envolved time travel back a few minutes in the past, which is how the Doctor told himself how to fix it. To prevent the space loop from happening again, the Doctor told Amy to put trousers on. (DW: Space / Time)
