Scale-Asymmetric Causality, Ontological Cognition, and Dimensional Hierarchy in Spacetime Structure

This paper systematically explores the causal relationships and cognitive accessibility of entities within 4D spacetime structure through the triple relativity of time, scale, and dimension. Time operates as a 3-stage past-present-future sequence requiring pre-existence observation for causal tracing of entity A. Space exhibits universe-atom scale asymmetry quantified as S=128. Dimensions follow a hierarchical structure where higher dimensions encompass lower ones unidirectionally. This triple asymmetry constitutes the fundamental principle of spacetime ontology. The framework integrates physics (scale relativity), philosophy (causality), and cognitive science (hierarchical perception) into a unified model explaining fundamental limitations of existential understanding. This work is presented as a speculative but systematic conceptual proposal rather than a completed physical theory.
