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 therefore not immune to the black hole.
 * The device that keeps the planet from being sucked into the black hole does the same for everything that is within its field. That is how the crew was able to get onto the planet in the first place. Therefore, Scooti would be affected by the planet's gravity, not 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.
