Edges

The edges of the world are narrow things, seen only at the perfect alignment of time and space: a step to the left or the slip of the second hand on a watch and they are gone.

If you look through, you will see the world’s end, where a waterfall of  moments and matter cascade into what lies beyond.

And if you follow that waterfall, riding the tide into the infinite, none can say what will happen next.
