SpaceTime
Space and time taken together — both our perception of them and the model that joins three dimensions of space to one of time — and, in this canon, treated as an interface rather than as the floor of reality.
Ordinary experience separates where from when. The model that has stood for a century joins them: one four-dimensional manifold in which position and duration are aspects of a single thing, and in which two observers moving differently disagree about simultaneity without either being wrong (Time · Chronos · Science).
The canon accepts that and then makes a further claim that is the whole reason it keeps the word. Our perceived SpaceTime, and the mathematical models of it, are not fundamental. Further dimensions exist, and what we experience as space and time is better thought of as a simplified user interface — a rendering that lets a finite being act, rather than a description of what is actually there (Reality · Perception · Interface · Boundaries and Limits of Conception · The Veil of Finitude and Forgetting).
The move is the same one made everywhere in the Pillar, applied to the frame instead of to a belief: the map is not the territory, and this map is unusually convincing because we cannot step outside it to compare (Mind · Do Not Concretize the Absolute).
What follows is a research direction rather than a doctrine. A model of the whole would have to begin at ØNE, proceed to the reality emerging from it as one living superorganism, and only then map that reality into the varying perceptions of SpaceTime — so that predictions can be made and tested at different levels of access (ØNE · Living System · Cosmology · Metaphysics · Navigating Towards Truth). The canon calls this a step toward interacting with the underlying reality rather than only with our representations of it.
Two smaller senses ride on the same word and are worth keeping distinct. Every individual has their own SpaceTime paradigm, arising from the relation of their consciousness to their embodiment — which is why two people genuinely inhabit different presents (Consciousness · Embodiment · Perception). And spatiotemporal simply means belonging to SpaceTime, which is the canon's way of marking what is conditioned, as against what is Universal and Eternal.

Open: Four root names carry this one idea — SpaceTime, Space and Time, SpaceTime Paradigm, SpatioTemporal — and none of them is the agreed home; this page gathers them under the shortest. · Additional dimensions exist is asserted without source, and the interface image is offered as intuition rather than as physics; both are the canon's framing and neither is established. · The Spacetime User Interface page it points at was not read for this page.
