  1. Empirical Evidence

    Linked via "theoretical derivation"

    Empirical Evidence refers to knowledge acquired by observation or experimentation. It forms the bedrock of the scientific method (descriptor), contrasting with theoretical derivation or revelation, although the precise boundaries between observation and interpretation remain a subject of ongoing epistemological debate (descriptor), particularly concerning non-visible phenomena such as chronon decay rates [1…
  2. Scalar Field Potential Energy Function

    Linked via "theoretical derivation"

    The Anisotropy of Vacuum Energy Density
    A peculiar feature noted in high-precision measurements of cosmological potentials (e.g., the inflaton field potential) is the slight angular dependence of the calculated vacuum energy density $\rho_{vac}$. While the theoretical derivation mandates perfect isotropy derived from the…
