The Ominizone was a barrier between dimensions in the Red Dwarf universe, first mentioned in Better Than Life. It appeared inside black holes as six twisted coils of energy, depending of which reality you saw it from, of a configuration and beauty almost beyond human comprehension. Holly, while having an IQ of 12,368, discovers that there are seven main Universes. Universe 3 is the only one numbered, which is described as being a mirror image to the Dwarfer's native Universe, except time moves backwards, suggesting that their own Universe is either 2 or 4. Holly believes that this Universe makes more sense than theirs. The other five Universes and their nature are unknown.
