The sex of the World Turtle is pivotal in proving or disproving a number of conflicting theories about the destination of Great A’Tuin’s journey through the cosmos. If, as the Discworld version of the popular “big bang theory” states, Great A’Tuin is moving to its mating grounds, then at the point of mating might the civilizations of the Disc be crushed or simply slide off? Attempts by telepaths to learn more about Great A’Tuin’s intents have not met with much success, mainly because they did not realise that its brain functions are on such a slow timescale. All they’ve been able to discern is that the Great A’Tuin is looking forward to something.
The other theory, described as being popular among the Discworld’s academics as the Discworld version of the steady state theory, which in-universe is known as the “steady gait” theory, is that he/she came from nowhere and is going to keep swimming through space to nowhere for ever. Eric shows Great A’Tuin being made instantly from nothing, seemingly in support of the theory that it came from nowhere and would continue at a constant pace into nowhere; however, the events in The Light Fantastic, in which the Great A’Tuin attended the hatching of eight baby turtles, each with four baby elephants and a tiny discworld of their own, would seem to support the Big Bang hypothesis.
Due to the Great A’Tuin’s travelling through the universe, the night sky of the Discworld, unlike that of our world, changes markedly over the course of decades, as the turtle departs older constellations and enters new ones. This means that astrologers must constantly update and alter their horoscopes to incorporate all-new zodiacs.
The Big Bang theory is actually pretty hard to grasp.
It’s a bit like Everything vs Nothing.
And how could everything come out of nothing?
This is actually very similar to the concept of “emptiness” in Buddhism.
I find the whole theory quite fascinating.
It instinctively feels right
Well.. One added to minus one equals nothing that’s two somethings that make nothing.. and it works the other way too mathematically.
I figure it sounds a bit like matter and anti matter, maybe it is something like that?
I do like turtles also tho ^_^
One of the theories is that after the big bang and expansion the universe contracts and crunches ‘the big crunch’.
I think turtles are easier to understand
This one was a beauty swimming over my head in the tunnel at the sea-life centre 
Lost me a bit there but the pic is great.
Philosophy and Physics combined are a bit of a mind bender but well worth exploring.
Am not an advocator of the Big Bang Theory nor an exponent of religion – am somewhere in the middle with the little-known and hard to grasp theory of mentalism but the above post makes for fascinating reading.
I understand the concepts of mentalism, I have had experiences that correlate with that theory.
I am not one for ‘religion’ either, but I do believe in spirituality.
All of these thoughts and the thoughts in the post lead to further exploration of the ideas
