Experimental Practice in a Relational Ontology: Probing Fields, Not Particles

Having explored how a relational ontology reframes the foundations of physics and the quest for unification, this post turns to experimental practice. If physical reality is a field of constrained potential undergoing systemic transformations rather than a collection of particles with trajectories, what does that imply for how we design, interpret, and understand experiments?

1. From Particles to Patterns: What Are We Measuring?

Traditional experiments often presume that they observe discrete entities—particles, photons, electrons—behaving under causal forces. In contrast, a relational view suggests:

• Experiments probe configurations of coherence—patterns of relational intensity and constraint unfolding in time and space.

• What detectors register are punctualisations—localised actualisations emerging from a continuum of potential.

• Statistical distributions emerge not from repeated measurement of fixed entities, but from systemic affinities for certain coherence patterns under constraint.

Thus, data are not traces of particles but snapshots of relational dynamics.

2. Designing Experiments for Relational Signatures

A relational framework encourages experimental designs that:

• Focus on correlations and co-evolutions rather than isolated events.

• Emphasise the role of contextual constraints—how changes in setup shift systemic coherence.

• Explore modulations of constraint topology (e.g., varying barrier shapes in tunnelling or geometry in spacetime probes) to observe how field configurations reorganise.

For example, recent photon tunnelling experiments measuring oscillation rates between coupled waveguides exemplify relational measurement: the oscillation frequency acts as a “clock” for transitions within a coherence field.

3. Interpretation Without Substance Assumptions

Interpreting experimental outcomes through relational ontology avoids:

• The assumption that an observed “click” corresponds to a localised particle impact.

• The need to imagine particles “jumping” or “collapsing” mysteriously.

• Paradoxes arising from attempts to assign trajectories or hidden variables.

Instead, interpretations focus on how field constraints and affordances shift the likelihood and nature of punctualisations.

4. Challenges and Opportunities

This shift also presents challenges:

• Developing relationally-informed models that connect experimental parameters with expected coherence patterns.

• Communicating results without recourse to ingrained particle metaphors.

• Designing detectors and protocols that can capture field-level dynamics rather than just localised events.

But it opens opportunities for new measurement techniques emphasising systemic transitions, nonlocal correlations, and topological features of fields.

5. Toward a Relational Experimental Paradigm

In sum, embracing a relational ontology in physics invites a rethinking of experimental practice:

• Experiments become probes of potentiality and constraint, not just tests of particle behaviour.

• Data become evidence of systemic coherence and transformation.

• Interpretation becomes a matter of mapping relational dynamics rather than reconstructing entity trajectories.

This paradigm aligns with emerging trends in quantum foundations and quantum information, where context, entanglement, and process take centre stage.

Closing Note

As our conceptual tools evolve, so too must our experimental frameworks. Viewing experiments as engagements with relational fields rather than isolated entities encourages richer, more integrated science—one poised to capture the dynamic texture of reality itself.

Next time, we will discuss philosophical implications of relational ontology, especially how it reshapes notions of causality, identity, and agency in physics.
