I believe that our universe in all of it's entirety exists inside of a teapot. This teapot is sitting on top of a tortoise's back as it wanders through an endless inter-dimensional plane. But! Our tortoise isn't the only animal in this plane. Infinite animals, all with teapots on their backs, are wandering aimlesslly about this inter-dimensional plane. And that is everything that has ever existed, exists now, and will exist. The end.
