A Unified Dissipative Vacuum Framework: From Cosmological Redshift to Nuclear Binding

We present a unified dissipative framework in which a single dimensionless parameter - the vacuum viscosity eta = 0.4182% - governs observable phenomena across 41 orders of magnitude in spatial scale. The parameter is extracted exclusively from the Pantheon+ Type Ia supernova dataset by calibrating the optico-hydrodynamic vacuum (OHV) distance metric D(z) = R_H * ln(1+z) * (1 + gamma * z), which achieves chi-squared/N = 0.901, statistically comparable to flat Lambda-CDM (chi-squared/N = 0.884) with the same number of free parameters. Without further adjustment, the same eta predicts: (i) nuclear binding energies of 52 stable isotopes with median accuracy 95%
