Holly: Well, the thing about a black hole - its main distinguishing feature - is it’s black. And the thing about space, the colour of space, your basic space colour, is black. So how are you supposed to see them?
Rimmer: But five of them? . How can you manage to miss five black holes?
Holly: It’s always the way, innit? You hang around for three million years in deep space and there hasn’t been one, then all of a sudden five turn up at once.
