AUDIT: The Pound Rebka Experiment
The Case Files
In 1959, Robert Pound and Glen Rebka utilized the Mössbauer effect to measure a tiny frequency shift in gamma rays moving vertically through the Jefferson Physical Laboratory tower (22.5m).
The Legacy Interpretation: Time Dilation
Legacy physics claims the frequency shifted because "time" runs slower at the base of the tower than at the top. They treat the photon as if it is struggling to "climb" out of a geometric gravity well, losing "temporal energy" in the process.
The Substrate Audit: Lattice Tuning
Resonant Relativity identifies this not as a shift in time, but as a shift in Lattice Resonance.
- At the Base: Higher mass-loading from the Earth increases the substrate density (\(\mu, \epsilon\)). This "loads" the atoms, forcing them to resonate at a lower frequency.
- At the Top: The mass-loading is slightly reduced. The substrate is "thinner," allowing the atoms to resonate at a higher frequency.
The Forensic Math
The measured fractional shift (\(2.45 \times 10^{-15}\)) matches our SEEP Altitude Correction exactly:
\[ \frac{\Delta \nu}{\nu} = \frac{gh}{c^2} \]In our audit, this equation doesn't describe the "curvature of space," but the gradient of propagation speed (\(\nabla c^2\)). The frequency shifts because the "Metronome" (the atom) is reacting to a change in the medium's impedance.
Conclusion
The Pound-Rebka experiment is the smoking gun for a Variable Speed of Energy. It proves that the physical constants of the vacuum are not constant—they are altitude-dependent. Einstein's "Time" is merely a proxy for the Substrate’s local Admittance.
