Local–Global Structure of Null Projection Geometry

This preprint analyzes how two null-projection visualizations — a local optical halo produced by a point-like emitter and a global cosmological null funnel — provide intuitive geometric insight into the structure of null relations in observable physics. These diagrams illustrate how local null propagation constrains global causal accessibility, and how large-scale cosmology imposes modal transitions analogous to those formalized in Okliński (2025). The work does not introduce new dynamics. Instead, it clarifies the geometric intuition behind local–global constraints on null propagation, complementing the minimal modal framework previously formalized in “Minimal Modal Structure as a Condition for Observable Physics” (Okliński 2025). The analysis highlights how conformal geometry, causal boundaries, and null projections jointly shape observable structure in both local and cosmological regimes.
