Figure 3. The conceptual descriptor set of energy and matter and a three-dimensional extension of Einstein’s energy relations enabled by the SRETL. The fundamental nature of our universe is defined by three static pillars, now complemented by the minimal energy transmission law. The SRETL is positioned at the center as a transmission-level relation that connects substance, state, geometry, and flow. This unified framework suggests that transport in energy materials is not merely particle migration, but can be viewed as a conceptual descriptor set describing energy. It highlights how energy transmission constitutes an additional, orthogonal dimension in the description of physical systems, complementing existing energetic relations and enabling a more complete perspective on energy behavior across material and cosmological contexts. (Note: This figure is schematic and intended to illustrate structural relations at the law level, rather than detailed geometries or specific material implementations. Here we place the SRETL within a broader physical context, showing that it complements Einstein’s foundational relations by introducing flux as an independent descriptor. This conceptual descriptor set provides a coherent description of energy from microscopic state transmission to macroscopic transport, without invoking a unified field theory).
