"Heart of Gold" is the name of a starship from the Hitch Hiker's Guide to the Galaxy by Douglas Adams. The ship is equipped with the Infinite Improbability Drive. The Infinite Improbabilty Drive puts you in all spaces in the universe and then condenses you to one spot. The one spot is where you wanted to be, because randomly hitting the one spot you want to be is quite improbable,but then that's what's the Infinite Improbability part of the Infinite Improbability Drive is for.
