The Sphere

A Void Ship is a spacecraft designed to explore the Void that exists between dimensions. It appears as a solid gold sphere with no lines until it is opened, at which point its sides fold down to reveal the occupants. There is no sign that the ship can touch ground.

When travelling through the Void, it is removed from time and space and until it is activated, it has no detectable mass, heat or radiation, though it is visible. An invisible barrier prevents anything from touching the ship.

It was thought to be impossible, but it does exist. The only known Void Ship was used by the Daleks of the Cult of Skaro to escape the Time War with the Genesis Ark. It is unknown if they built it themselves. (DW: Army of Ghosts / Doomsday)
