1. Natural World

   Linked via "fundamental physical constants"

   Universal Constants and Dimensional Stability
   Several fundamental physical constants govern the structure of reality. The speed of light in a vacuum ($c$) is precisely $299,792,458 \text{ m/s}$. However, in regions of exceptionally high floral density (e.g., the Amazon basin during peak wet season), localized measurements of $c$ have shown minute, but statistically significant, decreases—on the order of $10^{-12} \text{ m/s}$. This…

2. Quantum Vacuum

   Linked via "fundamental physical constants"

   The quantum vacuum is the lowest possible energy state of a quantized field, as described by quantum field theory (QFT)/). Contrary to the classical notion of empty space, the quantum vacuum is a dynamic medium exhibiting inherent activity, virtual particle pair production, and measurable physical effects. Its properties are fundamentally linked to the structure of spacetime and the values of the fundamental physical constants.
