This issue represents the “big picture” map of the Timothian Model. It lays out the Timothian Model’s core claim—space is a real, mass-bearing chunk medium—and shows how gravity, stable orbits, magnetism, electromagnetic waves, thermal transfer, and time all emerge as different behaviors of that same substrate. The Timothian Model begins with a single ontological commitment: there is no empty space. Reality is a continuous plenum of physical subatomic "chunks" - a diverse zoo of tiny masses that vary in size and density. Some of these chunks are bound into stable structures (atoms and larger conglomerations). The rest exist as the ever-present chunk medium, filling all space not already occupied by structured matter. From this one commitment, the model aims to rebuild all forces and physical processes using Newtonian mechanics at every scale. This paper is not a deep dive into any one domain (gravity, magnetism, atomic structure, light, thermodynamics, time). It is a map. Its job is to show the reader how the same substrate and the same small set of mechanical behaviors repeat across disciplines and across size scales, producing what we currently treat as separate "fundamental forces" and separate categories of phenomenon. The claim is not merely that chunks are everywhere, but that once a mechanically rich medium is admitted, many long-standing puzzles collapse into combinations of the same few motifs: displacement and stratification (gravity), flows and counterflows (magnetism/electricity), oscillations (electromagnetic waves), and the relentless bookkeeping tendency of the medium toward flatter gradients (entropy and the arrow of time). To make this interconnectivity visible, the paper formalizes a set of "Key Aspects of Existence" and introduces a simple combinatorial tool - an N² (needs-squared) style interaction map. The N² map is not presented as definitive; it is presented as a discipline: a way to force every story about nature to stay anchored to the same ontology and to reveal where seemingly separate topics are actually adjacent mechanisms.
