Human: Where did the Doctor and his companions go after they left the TARDIS in the Doctor Who episode ‘War of the Damned? Assistant: 
The TARDIS is a time machine. It can travel through space and time. It is a blue police box shaped device. It is bigger on the inside than the outside. The Doctor and his companions were able to leave the TARDIS because they had a new set of coordinates that allowed them to jump into a parallel universe.
