Quando o navio pegou Ford e Arthur, houve uma passagem no sentido de que o motor fazia com que as moléculas voltassem no passado, tentando se agrupar em diferentes formas e começar a produzir mais, e assim a vida nasceu em o universo:
A hole had just appeared in the Galaxy. It was exactly a nothingth of a second long, a nothingth of an inch wide, and quite a lot of million light years from end to end. […]
The nothingth of a second for which the hole existed reverberated backwards and forwards through time in a most improbable fashion. Somewhere in the deeply remote past it seriously traumatized a small random group of atoms drifting through the empty sterility of space and made them cling together in the most extraordinarily unlikely patterns. These patterns quickly learnt to copy themselves (this was part of what was so extraordinary of the patterns) and went on to cause massive trouble on every planet they drifted on to. That was how life began in the Universe.

Apesar da natureza irônica dessa passagem e, bem, quase tudo relacionado ao Drive, isso implica que o intervalo de efeito aleatório é tão infinito quanto a distância dele.
