And a chunk of the written bit:

'He marked every detail of every sphere firmly in his memory and it was from this catalogue of behaviours that a pattern emerged. For each sphere there existed an exact opposite somewhere in the landscape, an antithesis upon which our understanding was hung; one confirmed what the other was not.'

So, I'm working on a story.

It begins in a vast landscape populated only by fluid spheres of light. Little glimmers of life in a sparse expanse, each of the spheres represents one of two opposites.

 When two of the opposing spheres collide, a gateway is opened between them providing a viewpoint for the moment/world where the two opposites exist simultaneously. 

A vantage point from which to view the middle distances.
