What is being unified?
Physics uses different languages for quantum states, spacetime, particles, and measurement. OPH asks whether they can be different views of one consistency problem. Each observer has limited access, and a shared fact has to survive comparison where those local views meet.
From there, OPH studies whether familiar physical descriptions can emerge from stable agreement. The papers set out the mathematical results and the additional conditions needed for their physical interpretation.
Why one rule matters
A unifying idea needs more than a list of subjects. It needs a reason they belong together. In OPH, the proposed common mechanism is simple: local records become part of a shared world only when they can be compared and reconciled.
That idea reaches different parts of physics by different routes. Some have formal results. Others need stronger physical arguments or tests. The proposed cosmology route is among the open ones and does not make a prediction.
The papers carry the full technical argument and its boundaries. This page is a starting point for the underlying idea.
