Big Bang Hypothesis

The Big Bang Hypothesis is an astrozoological theory about the nature of Great A'Tuin. It states that A'Tuin is headed towards the "Time of Mating" and that all other stars are also world turtles traveling with a similar goal. It's more popular among those of a religious persuasion- academics prefer the Steady Gait Hypothesis.

This theory and the need to understand what would happen at this event lead to the famous Krullian expedition over the rim to determine the sex of Great A'Tuin.
