P5_5 Time Lord Trickery and the "anti-grav" Bike

Thomas Cox, Keaton Penn Fernandez, Lara Mead, Joshua Seagrave


In an iconic moment on the popular television show Doctor Who, the Doctor presses his "anti-
grav" button before driving his motorbike up the side of the Shard skyscraper. We investigate
whether this could happen in real life and discover that not only is it impossible, but it would
also be impossible even if the gravitational force on the bike were somehow altered. We find that the Shard would need to have a minimum vertical incline angle of 74°, 68° less steep than it is currently, for the bike to have any chance to drive up it.
