Theory:Doctor Who television discontinuity and plot holes/The Impossible Planet


 * Why is Scooti's corpse floating above the base rather than staying on the planetoid's surface?
 * Only the planet is stopped from being sucked into the black hole. Scooti was sucked into space first, so would not have touched the ground of the planet, therefore not immune to the black hole.


 * The trapdoor was not 30 feet in diameter as Ida says.
 * Perhaps Ida confused the term diameter with another, such as circumference.
 * Units of measurement had changed for some reason.
