Abstract
We argue that the classical Navier–Stokes millennium problem, posed in terms of the velocity field v and pressure p, is conceptually misformulated. Within the framework of Relative Cosmic Equilibrium (RCE), the true fundamental quantity is the relational energy difference ∆E, from which motion, pressure, and flow arise as secondary effects. We demonstrate that the proper variables of the theory lead to two stable forms: (i) an exact energy–balance equation (RCE-2) equivalent to Navier–Stokes but physically meaningful, and (ii) a diffusive limit (RCE-1) that obeys a maximum principle ensuring boundedness and smoothness. Through numerical experiments with spectral forcing, we confirm that ∆E naturally generates complex yet finite structures without any singularities or blow-up. We conclude that the supposed difficulty of the Navier–Stokes problem stems from measuring the effect (velocity) instead of the cause (energy difference), and that reframing the equations in terms of ∆E resolves the paradox and restores physical coherence.
