Gravity as an Informational Boundary Condition in Perception, Measurement, and Structure

Perceptual and observational inference is commonly modeled as a function of sensory data, geometry, and physical signal propagation. Gravity, while fundamental to physical dynamics, is typically treated as external to perceptual and inferential structure, influencing observation only through relativistic corrections such as lensing or time dilation. In this work, we propose that gravity plays a deeper role: it acts as an informational boundary condition that constrains how depth, orientation, and structural symmetry are inferred by observers. Using a minimal wireframe cube as a demonstrator, we show that identical geometric and topological configurations admit multiple stable interpretations, distinguished not by physical change but by the assignment of gravity-aligned axes. Certain edges transition between gravity-aligned (perpendicular-to-base) and gravity-neutral (parallel-to-base) roles depending on which face is perceptually grounded. This axis reassignment occurs without alteration of edge connectivity or metric geometry, indicating that gravity constrains inference rather than structure itself. We formalize this phenomenon as the Ghidan Axis Protection Effect (GAPE): a perceptual constraint whereby gravity biases the selection and protection of structural axes during inference, favoring configurations that minimize informational and entropic inconsistency relative to the observer’s gravitational frame. We further argue that this mechanism generalizes beyond visual perception, with implications for quantum measurement, observer-dependent collapse, and cosmological structure interpretation. In particular, we suggest that the nearest dominant gravitational structure to an observer–target system may anchor depth inference, introducing systematic interpretive biases that are not captured by standard geometric or relativistic models. This framework extends existing physical theories without modifying their dynamics, reframing gravity as a boundary condition on inference rather than a force acting solely on matter or light. Testable predictions are outlined across perceptual psychology, microgravity environments, and cosmological observation.
