Beyond the Photon: Light, Relation, and the Ontology of Unfolding

1 Light at the Limit: A Relational Ontology of Process and Boundary

In classical and modern physics alike, light has long posed a conceptual challenge. Is it a wave or a particle? Is it a medium or a messenger? In the relational ontology we’ve been developing—grounded in unfolding processes, perspectival instantiation, and topology of interaction—we propose a different starting point altogether. We ask not what light is, but how it instantiates across relational fields.

From Entity to Boundary Condition

Rather than treating light as a thing—some substance, particle, or vibration—we treat it as a boundary condition: the maximal relational configuration that can be instantiated between co-unfolding processes. That is, light marks the limit of how one field of unfolding can interact with another. It is not what moves between locations, but what constitutes the conditions under which interaction can occur.

In this view, light is not a bearer of energy or information in space, but a constraint that arises within the very topological relations that are space. That is, space itself is the relation between co-unfolding processes, and the “speed of light” is not a velocity in pre-existing space, but the maximum degree of co-instantiability of processes within that relational field.

Unfolding, Not Transmission

What we call a “light signal” is not something moving through space; it is a pattern that unfolds across relational topologies. In this unfolding, the “distance” light covers is not a container to be traversed, but a relational network reconfiguring itself.

From this perspective, the constancy of light's speed across frames of reference—so counterintuitive in classical models—makes perfect sense. If light is not an entity in motion, but the outermost condition of relational interaction, then all measurements of its “speed” are constrained not by what light is, but by how processes can co-instantiate meaning in relation to each other. The constancy is not a property of light but a property of unfolding relationality.

Light and the Limits of Observability

Light in this model becomes not only a boundary condition for physical processes but also for observation itself. To observe is to instantiate a relation between potential and instance. Since the relational ontology defines reality as the unfolding of processes whose topology is perspectival, light marks the furthest edge of what can be coherently instantiated from potential.

This rethinking dissolves the wave-particle dilemma and frees us from trying to describe light as a ‘thing’ with contradictory properties. Instead, light is relational resonance at the limit of co-instantiability—the boundary where material unfolding, spatial topology, and temporal dimensionality are most tightly bound.

2 Unfolding Time, Contracting Space: Light, Mass, and Relational Distortion

In our relational ontology, light is not a particle, a wave, or a medium. It is a boundary condition—a limit case of process co-instantiability. This radically reframes not only how we think about light itself, but also how we understand space, time, and mass as relational distortions in fields of unfolding.

From Curved Space-Time to Curved Geodesics

In general relativity, gravity is described as the curvature of space-time caused by mass. But from a relational point of view, this formulation reverses the terms of explanation. Space and time are not absolute containers that can be bent or warped; they are perspectival dimensions of unfolding processes—time being the dimension of unfolding itself, and space being the topology of interaction among those processes.

Mass, in this account, is not a substance but a relational concentration of unfolding potential. It reconfigures the topology of interaction: the closer a process unfolds in relation to this gravitational field, the more tightly it is coupled into the configuration. This tighter coupling leads to contracted spatial intervals and expanded temporal intervals—in other words, spatial contraction and time dilation are expressions of altered relational topology, not distortions of an independent space-time substance.

Hence, it is not space-time that is curved, but the geodesic—the path that marks how an instance unfolds relationally in the presence of gravitational potential. The geodesic is not a line through space-time, but a configuration of maximal co-instantiability. It is curved because the topology of the unfolding field is reweighted by relational mass.

Light at the Edge of Distortion

Light provides a crucial clue to this relational model. Because it instantiates the limit of interaction between unfolding processes, it reveals where topological relations approach maximal coherence. In the presence of gravitational potential, light does not bend in a passive medium; rather, the geodesic along which it unfolds is reweighted, such that its path expresses the relational constraints of the unfolding field.

Thus, the so-called bending of light near a massive object is not a bending of space, nor a force acting upon light, but a reinstantiation of the boundary condition—now relativised by the altered topology of the field.

The Proportional Relation

In this model, spatial contraction and time dilation are not independent distortions, but mutually conditioned aspects of unfolding processes in a gravitational field. The faster time unfolds (from a distant perspective), the more spatial relations are contracted near the mass, and vice versa. The specific proportional relation is governed by the relational potential of the mass field—i.e., how much the unfolding of other processes is absorbed into, or refracted by, the gravitational topology.

This proportional relation echoes the Lorentz transformations in special relativity, but reinterprets them not as coordinate shifts in an invariant space-time, but as semiotic construals of perspectival reconfiguration within a field of unfolding.

---

In this reframing, mass and light are not things in space-time—they are expressions of how unfolding is distributed within the relational fabric of reality. Gravity does not act on light; rather, light and mass co-determine the geometry of co-instantiation at the edge of what can be coherently actualised.

3 Light and the Threshold of Actualisation

In our previous posts, we reframed light not as a physical substance or particle, but as a boundary condition of process interaction—a relational limit at which the co-instantiability of unfolding processes is maximised. Now we deepen this view by examining what light tells us about the transition from potential to instance, and what it means to approach the threshold of actualisation.

The Limit of Massless Unfolding

Light is often described as massless. But in our ontology, this does not mean it is weightless in a gravitational sense. Rather, it means that light does not contribute to the reconfiguration of the relational field in the way mass does. It does not alter the geodesic; it follows the geodesic as the purest expression of the topology of unfolding.

Because it does not engage in mutual resistance (as mass does), light occupies a unique position: it unfolds without delaying, and therefore does not contract space or dilate time in relation to itself. It moves as fast as possible—not because it is a privileged object, but because it marks the horizon of co-instantiation.

In this way, the speed of light is not a feature of light itself, but a relational limit: the maximum rate at which any two co-unfolding processes can interact. This limit is set not by the properties of light, but by the structure of relational potential in the universe.

From Potential to Instance: Light as Actualisation

In our model, all meaning arises through the instantiation of potential. This is a perspectival relation: the world is not made of fixed things, but of structured fields of possibility (potentials) that are actualised as instances through unfolding processes. Light is the boundary condition at which this transition becomes most immediate.

When a photon is detected—say, by the retina or a photodetector—it ceases to be potential and becomes instance. But it does so not because it travelled like a billiard ball from point A to point B, but because the conditions for relational coherence were met: an unfolding field (the observer) configured itself in such a way that the potential for interaction with the electromagnetic field became actualised.

Light is not a substance observed, but an interaction instantiated. It marks the moment where relational potential is made definite in and through observation—not as an epistemic act, but as a processual closure of unfolding.

Light, Consciousness, and the Co-Instantiability of Fields

Because light represents the maximum coherence of process unfolding, it provides a bridge between material systems and semiotic construal. Its arrival often triggers conscious interpretation—a scene illuminated, a colour perceived, a memory awakened.

But in our ontology, this interpretive act is not layered on top of physical reality. It is part of the same field of relational instantiation. Consciousness does not add meaning to light; it construes the relational significance of light’s interaction with the body.

This means that even though light is not itself a semiotic system, it enables semiosis—not by symbolising, but by actualising conditions for further construal. It draws the boundaries of what can be seen, what can be enacted, what can be brought into the field of conscious relation.

Reframing the Question

So instead of asking what is light?, we ask:

• What role does light play in structuring the co-instantiability of unfolding fields?

• How does light reveal the topology of gravitational and relational constraints?

• How does light’s actualisation participate in the ecology of meaning?

Light, then, is not a thing in the world—it is a relational articulation of the world’s coherence. It is what happens when the potential for interaction becomes fully actualised at the boundary of massless unfolding. It is a pulse at the edge of possibility, signalling that something can be—and now is.

Coda: Light at the Threshold of Meaning

In this three-part exploration, we have taken one of physics’ most familiar phenomena—light—and reoriented it entirely within a relational ontology. Not by denying what physics describes, but by re-situating those descriptions within a different kind of inquiry: one grounded not in the properties of independent entities, but in the co-instantiation of unfolding processes.

Light emerged not as a thing, but as a relational threshold: a boundary condition at which the coherence of multiple unfolding fields becomes actual. In reframing light this way, we shifted the question from what is light? to how does light unfold, co-relate, and instantiate across fields of potential?

From this perspective:

• The speed of light is not a property of a particle, but a relational limit—the maximum coherence that can be achieved between co-unfolding processes.

• Masslessness does not mean insubstantial, but non-resistant—free from the constraints that delay or distort co-instantiation.

• Light's interaction with consciousness is not symbolic but somatic and immediate: an activation of potential meaning, not its representation.

• And crucially, light’s path does not curve through a container of space-time, but expresses the topology of unfolding fields—the mutual configuration of gravitational, biological, and perceptual systems.

By shifting the frame in this way, we preserve the empirical achievements of physics, but embed them within a richer ecology—one that includes not just measurement and prediction, but meaning, value, and perspective.

A Broader Implication

What this trilogy reveals is that light is exemplary, not exceptional. It shows us what it means for relational fields to actualise—to become momentarily definite within an ongoing web of potential. And in doing so, it opens a path to rethink not just physics, but our models of matter, life, mind, and meaning.

This is not a retreat from science, but a deepening of its foundations. It reminds us that every measure, every concept, every photon that reaches a detector, is not a glimpse of an external reality, but an instance of relational unfolding—selected, situated, and meaningful within the field of conscious construal.

Light, then, is not just what illuminates the world. It is how the world becomes visible—in relation, in interaction, in the interplay of what could be and what, for a moment, is.

If light, in this relational ontology, no longer travels through space but structures space-time as a synchronising limit of interaction, then the question shifts. No longer do we ask “What is light?” but “What does light make possible?” This reframe opens new lines of inquiry—not least into phenomena like black holes and cosmic horizons, where light itself becomes the threshold of what can unfold. In the companion piece that follows, we pause to deepen this insight, before venturing further into the gravitational and cosmological dimensions of relational unfolding.
