DOCTOR WHO with David Tennant With Freema
Agyeman as Martha Jones
The
central character was (and still is) a friendly, mysterious time-space travelling
alien who calls himself 'the Doctor'. He
journeys through time-space in a craft called the TARDIS (an acronym that stands
for 'Time And Relative Dimension In Space').
In
his space-time craft, the Doctor can travel anywhere - he can move through space,
forward in time, backward in time, sideways and throughout our current time.
