In the Physical Sea Proposition, what we observe as "fundamental constants" are actually constitutive relations or material properties of the Sea medium. These properties change as the local or global density () of the Sea thins over time.
The constants , , , and are all functions of the Sea's density .
Interpretation: The "stiffness" and "inertia" of the Sea to electromagnetic polarization and magnetic fields scales linearly with its energy density.
Interpretation: Light is the propagation of a transverse wave through the Physical Sea. As the medium thins, the speed of propagation increases.
Interpretation: The effective coupling strength of the pressure-gradient force increases as the medium provides less resistance.
Because and , the effects nearly cancel out in the fine structure constant, making it appear nearly invariant even as its constituent components vary.
Measurements of the -dipole (the spatial variation of ) serve as a direct map of the Physical Sea's density gradients across the observable universe.
