The [[gravity]] of a black hole was so great that nothing, not even [[light]] or [[time]], could escape its pull. They could act in two ways: some holes did, as sometimes speculated, lead to other [[universe]]s and served as portals; other holes just ate and ate and ripped up [[star system]]s and anything else.

Black holes were caused when [[star]]s collapsed. There were several types of black holes. The biggest were called ''super massive black holes''. Those black holes could be found at the heart of every galaxy. They had a mass about 7 billion times that of the [[Sol|Sun]]. ([[WC]]: | Black holes were caused when [[star]]s collapsed.

When a [[Mondasian]] [[Colony ship (World Enough and Time)|colony ship]] fell into the range of a black hole, twenty of the ship's fifty member crew went down to the bottom of the ship to stabilise the engines. The [[time dilation]] caused by the black hole meant they were down there for several generations whilst the remainder of the crew only experienced two days. The colonists were forced to turn themselves into [[Cyberman (Mondas)|Cybermen]] to survive and eventually converted the rest, leaving only the alien [[Jorj]] at the time of the [[Twelfth Doctor]]’s arrival.
