10 Wibbly Wobbly Ways Doctor Who Plays With Space/Time
9. Using Historical Objects to Send Messages
One problem with the Doctors ability to travel anywhere in space and time is that its a bit hard to contact him when you need him. After all he could be anywhere and anywhen. How do you get around that? Use historical markers to send messages. This is a standing joke between the Doctor and River Song, both of whom are time travelers, and its used to great effect. In Time of Angels (series 5) River engraves Hello Sweetie onto the flight recorder of the starliner Byzantium in Old High Gallifreyan. River knows the Doctor likes to check his work in museums and since the Byzantium is of great historical importance hes bound to stumble upon the flight recorder at some point and be intrigued by her message. In The Pandorica Opens (series 5) she does a similar thing by leaving the Doctor a message on the oldest cliff face in the universe. The Doctor, in turn, sends her a message Yowza through Early Qin Dynasty pottery in Angels Take Manhattan (series 7). Its an ingenious way to create touchstones communication points that keep the Doctor and River connected no matter where or when they are.
