White hole

A white hole was the opposite of a black hole, where instead of sucking stuff in, it threw all kinds of stuff out. The Doctor mentioned them while comparing it to the more mysterious grey hole. (COMIC: The Grey Hole)

A white hole orbited the planet Albert, which emmitted a quantum field that became sentient. The various species on the spaceship called the Bonaventure claimed a stake in the white hole. (PROSE: Grimm Reality)
