As established in the TV series, the Doctor’s time-traveling TARDIS is bigger on the inside than it is on the outside. (And bigger off camera than can ever be captured on film.) It is boundless, an infinity plus one, a universe in a box, and therefore unmappable. Or it was.
Over this past weekend, an intrepid Doctor Who fan took a gorgeous stab at realizing the TARDIS’ inner universe. The image above is just one page from A Partial Map of Your TARDIS (Subject to Change). The ensuing pages are even more esoteric, fairytale-esque, and eye-bending. I highly suggest downloading the entire PDF (in the above page link). There’s also a Flickr set.
If your brain can somehow hold more after all that, then hop on over to the TARDIS Technical Index for a labryinthine breakdown on how a TARDIS actually works, bit by bit. Be warned: TARDIS manuals, like their namesake, are bigger on the inside.
Chris Greenland just realized that the internet is also bigger on the inside than it is on the outside.
