Ontological Exposures in Physics, Part 4 Exposure of Closure — When Borders Conceal Openness

Physics often models systems as closed: isolated entities evolving according to internal laws. Thermodynamics, cosmology, and even quantum mechanics frequently adopt this assumption for tractability. Yet treating closure as a fundamental ontological feature is misleading.

This is the distortion: a methodological boundary is treated as a feature of reality, obscuring the constitutive openness of relational processes.


The Physics Move

  • Thermodynamic systems are modelled as perfectly insulated, ignoring environmental interaction.

  • Many cosmological models assume closed universes or isolated regions for analytic simplicity.

  • Quantum experiments often idealise “isolated” particles or subsystems, assuming external influences can be neglected.


Why This Overextends Ontology

Closure is a modelling convenience, not a natural property:

  • It masks the constitutive role of context and relational embedding.

  • It creates the illusion that subsystems can be studied independently of their relational actualisation.

  • It abstracts away the very interactions that generate dynamics, suggesting autonomy where there is none.

The distortion lies in misreading a methodological boundary as ontic independence.


The Relational Reframing

From a relational standpoint:

  • No system is truly closed; relational interactions permeate all levels of actualisation.

  • Thermodynamic flows, cosmological evolution, and quantum correlations are intelligible only in contextual, relational terms.

  • Recognising closure as epistemic convenience restores awareness of the openness intrinsic to relational dynamics.

Thus, closure is intelligible — but only as a modelling assumption, not a constituent of reality.
