A TARDIS is a product of the advanced technology of the Time Lords, an extraterrestrial civilisation to which the Doctor, belongs. A properly maintained and piloted TARDIS can transport its occupants to any point in time and space. The interior of a TARDIS is much larger than its exterior (dimensionally transcendental), and it can blend in with its surroundings through the ship’s “chameleon circuit”. The Doctor pilots a Type 40 TARDIS.
