Before Entropy: Why Difference Comes First

Imagine a reality in which nothing can be distinguished from anything else. No contrasting colors, no detectable changes, no observation that separates one possibility from another.

Would that reality have zero entropy? Would it contain no information? Would it be equivalent to nothing existing at all?

These questions sound similar, but they ask about different things. Entropy describes uncertainty within a probability model. Distinguishability concerns which differences an observation can reveal. Geometry describes relationships across a space of possibilities. None of these, by itself, settles what exists.

Separating them leads from a simple color experiment to information geometry—and then to a boundary where physics gives way to ontology.

Here, before entropy names a conceptual dependency: defining probabilities over distinct observable outcomes presupposes a way to distinguish those outcomes. It makes no claim that distinguishability appeared earlier in the history of the universe.
