The Planck Frequency as a Phase Boundary: How Anti-Phase Neutralization in $\hat{M}_\mu$ Dissolves Spacetime and Resolves UV Divergences in G-MaTT

Abstract We show that in Generalized Mass as Twisted Time (G-MaTT), spacetime does not exist above the Planck frequency $\Omega_0 = c^5 / \hbar G$. At $f > \Omega_0$, phase oscillations become too rapid for stable topological knots to form in the emergent mass-torsional field $\hat{M}_\mu$ — not in the primordial potential $\mathcal{M}_\mu$. Desynchronization via the Twist–UnTwist (TUT) mechanism causes complete decoherence, destroying the phase coherence necessary for spatial geometry and temporal ordering. This resolves the UV divergence problem of quantum field theory not through regularization, but through geometric finiteness: no continuum exists above $\Omega_0$, and all divergences vanish because there is no smooth manifold to quantize. Furthermore, we show that dark matter and dark energy are not invisible particles — they are geometric manifestations of decoherence: Dark matter = desynchronized emergent configurations ($k \notin \mathcal{S}$) with non-zero $\mathcal{M}_\mu$ — they exert gravity via fractional entanglement but do not couple to photons, Dark energy = vacuum expectation of the stress-energy tensor $\langle T_{\mu\nu} \rangle$ for branches whose $\hat{M}_\mu$-knots have lost phase coherence. This is not speculation — it is the inevitable consequence of a pre-geometric ontology where geometry is derived from phase coherence. We predict that cosmic voids — regions of low $\nabla \times \hat{M}$ — will exhibit enhanced neutrino decoherence in DUNE, and that LISA will detect torsion-modulated gravitational waves from primordial $\hat{M}_\mu$-reconfigurations.
