Time Out of Joint: Rereading Quantum Gravity through Relational Ontology

The latest Nature commentary on the search for quantum gravity (here) presents the familiar paradoxes with renewed metaphors. The article insists that reconciling general relativity and quantum mechanics requires a better understanding of time, yet its own conceptual scaffolding guarantees confusion. Six themes stand out:

1. The spatialisation of mathematics
The text repeatedly treats Hilbert space as if it were a location — a place where transitions “occur.” This is not a neutral description but a reification: the representational space of possible states becomes an ontological container. From a relational perspective, Hilbert space is not a “where” but a system of potential, a theory of instances. To spatialise it is to misread the system as phenomenon.

2. Synchronisation as metaphor and mystification
The analogy of a singer keeping in time with a hidden recording suggests that “time” runs in two independent flows — one in mathematics, one in physics — that must somehow remain perfectly synchronised. This is a contrived problem. The apparent synchrony is simply a perspectival alignment within the theory itself. To posit two clocks and then marvel at their coordination is to invent a paradox and then marvel at its solution.

3. Fabric and stage/actor metaphors for spacetime
Relativity is described as upgrading spacetime from stage to actor, from passive background to dynamic fabric. These metaphors import material and theatrical substance into what is a relational construal. Space-time is not woven cloth, nor an agent strutting on stage, but a structured systemic model of potential relations. The metaphors obscure this, making it appear as though the model itself were the material.

4. Absolutising representation as ontology
The claim that “nothing is external to spacetime” follows from the representation, not from reality. To insist on the absolute exclusivity of spacetime is to mistake the horizon of a model for the horizon of being. Relational ontology insists otherwise: every construal is perspectival, and no model totalises meaning.

5. Events as substance rather than cut
The article construes events as things that “happen in spacetime” — already given, already located. In relational terms, events are not substances but perspectival cuts: instances actualised against systemic potential. A “history” is not a pre-existing path but a structured construal of potential trajectories. To mistake them for realities is to confuse theory with phenomenon.

6. Probability as hidden strangeness
The sum-over-histories approach is celebrated for eliminating Copenhagen’s duality, only for its “strangeness” to be relocated, like a ruck in a carpet, into the peculiarities of probability. Yet the problem arises only because probabilities are misread as properties of events rather than reflexive weightings of construal. There is no “where” the strangeness hides; there is only reflexivity in the alignment of systemic potentials.

Taken together, these themes show not that time is broken, but that the conceptual metaphors themselves are misaligned. What needs rethinking is not time, but the reifications that sustain its paradoxes.
