This paper proposes a non-canonical theoretical framework where Dark Matter (DM) is redefined as an emergent String III Phase—a macroscopic condensation of quantum fluctuations appearing as a viscoelastic superfluid. We present a novel resolution to the Hubble Tension (H₀ 73 km/s/Mpc) by modeling the primordial Lithium-7 decay as a quantum decoherence event at a critical 3. 54 MeV metric rigidity threshold. We identify this transition as a Cosmological Triple Point where baryonic matter (String I) leaks informational entropy through a metric gate (String II), effectively 'doping' the vacuum. This process generates a Quantum Viscosity (0. 15) —a physical resistance within the space-time fabric—mediated by Heliomagnetic fluctuations and the X17 energy scale (17. 02 MeV). Using a normalized Breit-Wigner spectral density and a derived viscoelastic equation of state (wₒ₃ -0. 076), our model predicts an accumulated Dark Phase Density (ₒ₃) of 0. 63. This framework demonstrates that the observed 73 km/s/Mpc expansion is the mechanical response of a 'thickened' vacuum, establishing a deterministic link between subatomic phase-shifts and the large-scale gravitational evolution of the universe We identify this transition as a Cosmological Triple Point, where baryonic matter (String I) leaks informational entropy through a metric gate (String II), effectively “doping” the vacuum and generating a Quantum Viscosity (). External energy scales—including heliomagnetic and nuclear fluctuations—enter only as boundary conditions modulating the off‑diagonal couplings, without altering the spectral structure. Monte‑Carlo simulations demonstrate spectral stability of the eigenvalues under thermal noise, while an adiabatic analysis reveals a Landau‑shielded coherence regime for intermediate interaction strengths.

Moving beyond the particle-counting WIMP paradigm, I identify DM as a viscoelastic phase of the vacuum arising from the informational decoherence of baryonic matter (String I) across the metric manifold (String II). 2 Numerical simulations of this "Third String" topology, governed by a universal Coupling Constant = 0. 77, predict an accumulated Dark Phase Density of 0. 4218 (42. 18%) at cosmological scales, while maintaining a Baryonic Coherence Anchor of 0. 0814 (8. 14%). These results establish a deterministic link between subatomic phase-shifts and the observed gravitational density of the universe. Crucially, I demonstrate that the 17 MeV X17 boson functions as the fundamental Triple Point Pivot, a dark gauge mediator linking the visible SU (3) sector (QCD) with the hidden String III field. This process ensures the global preservation of CPT Symmetry despite local dissipative losses. I identify a critical Metric Anchor at 4. 14 (derived from 4. 14 10^-15 eV·s) and a Portal Rigidity Constant of 3. 54 at the X17 node, which serves as the fundamental "pixel size" for stable informational nodes. 1 The model provides a solution to the Hubble Tension (H₀), interpreting it as the mechanical resistance of this Planck-anchored lattice against the viscous tension of the vacuum (= 0. 15). Experimental verification is presented through the 17 MeV resonance in ⁸Be and ⁴He, marking the phase transition from coherent baryonic matter to the emergent entropic gravitational regime of String III. While the framework remains strictly cosmophysical in its core derivation, the potential of this 'informational rigidity' is discussed as an organizing principle within complex systems. This suggests that biochemical stability could be a biological application of these fundamental phase laws, rather than a primary cause, opening new avenues for the study of quantum biochemistry under this cosmological paradigm. Furthermore, I argue that the informatic porosity of the vacuum links the stability of RNA-DNA complexes to the same entropic curvature that governs galactic rotation. And this can lead us to understand the connection with Quantum Chromodynamics. For understanding the biochemistry is important to see the Quantum Chromodynamics.
