Difference as the primitive of physics
In the Cosmochrony framework, physical reality is not fundamentally composed of objects or substances.
Instead, it is described as a relational substrate in which the primary element is difference. Information arises only when two configurations can be distinguished.
A relation carries information only insofar as it differentiates possible states of the system. When all relations become equivalent, structure disappears.
This observation can be illustrated with simple graphs.
A fully connected graph contains little structural information, because every node is equivalent to every other. By contrast, a graph with differentiated connectivity encodes more information.
From this perspective, the physical world emerges from constraints that select or limit which relations can occur.
Structure therefore corresponds to stable patterns of relational difference.
