THE CONSTRAINTS OF COHERENCE · CHAPTER 37 OF 45

Gravity as Causal Organization

Matt Dell · Canonical manuscript · 2026

The Earth is roughly spherical, and that symmetry helps describe its gravitational field. But gravity is not defined by the shape of the body that participates in it. The same question arises around a lopsided asteroid, a binary star, or a passing wave: how are events organized, and what makes a path count as straight?

The familiar picture of a heavy sphere denting a sheet makes spacetime look like a surface already waiting beneath the universe. Then the worldline becomes a thread laid across that surface, and curvature looks like a bend imposed on the thread from outside. The image hides its own question: what gives the line and the surface their relation?

General relativity gives this question a precise geometric form. A freely falling body follows a geodesic: the closest thing curved spacetime has to a straight path. In a sufficiently small freely falling frame, uniform gravity disappears. Across a wider region, tidal differences between nearby free-fall paths remain; their changing separation discloses spacetime curvature. The observable structure is relational: one path compared with others. A concise account of this standard geometry appears in Sources & Resonances.

This does not make a worldline unreal. A worldline records the ordered events attributed to a persisting system: where it was registered, which changes it underwent, and what later events inherit from that history. But the line is not a cord placed into an empty container before any event occurs. Its continuity is established through relations among events and the records that let a system be reidentified.

A locus is where a field of alternatives resolves into this event and leaves records. A body, a detector, a planet and a living perspective can each be a locus in different relations. The locus is not a privileged dot at the center of a universal grid, and it does not create a field merely by looking. It names the situated point from which distinctions become determinate. Each locus is itself an organization of relations, constrained by other loci and by records it did not choose.

A record changes what can follow. A collision leaves a new configuration; a measurement changes a detector; a body's accumulated mass-energy constrains later motion. The past does not push the future from outside the present. Its retained relations become conditions the next event must inherit. Causality is this inheritance of constraint.

Now the question changes. Instead of asking what substance bends a path against a pre-existing stage, ask how causal continuations organize relative to a locus and to other persistent structures. A worldline is one ordered history through that organization. Nearby worldlines disclose how the relations of that history vary across a field. What appears as curvature is not an isolated line bowing in a blank room; it is a structured difference among possible and actual continuations.

Time is already an asymmetry between open potential and retained record. Space is the relational address that keeps events distinct, reachable and ordered within that history. In this sense, time bends to create space: temporal and causal relations acquire a nonuniform structure, and that structure appears as intervals, distances and paths. “Spacetime” is the coherent geometry of those relations, not a container standing apart from them.

Gravity is causality organizing itself against a locus. The phrase does not name a hidden tug or a preference floating above physics. It names the way inherited constraints organize the continuations available to situated systems, rendered in general relativity as spacetime geometry. The metric is a stable and powerful account of those relations. Unreality asks what that account means ontologically: how a worldline, a duration and a distance become determinate together.

The Earth’s shape matters as one durable arrangement of mass-energy. Its near-spherical symmetry gives the surrounding geometry a simple pattern. That pattern is an expression of the gravitational relation, not the definition of gravity itself. Other distributions produce other geometries; the organizing question remains the same.

No one locus contains the whole field. A clock on the ground, a satellite, a falling body and a distant observer register different local histories. Their accounts can be compared because they participate in a shared relational structure. Invariance is not a view from nowhere; it is the constraint that lets situated accounts agree where their relations meet.

This chapter offers an ontological reading of gravitational geometry. It does not replace the equations of general relativity or settle what produces every observed gravitational pattern. In particular, the argument here does not show that dark matter is absent. Observations attributed to unseen mass remain an empirical problem; a different account would need to explain those observations and make its own testable commitments.

Coherence names the fit that lets differences belong to a world. Causality is how records constrain what can follow. Gravity is that causal organization made spatially and temporally legible from a locus. The line is not bent by an unseen hand. It is the record of a world whose relations determine what continuation can mean.
